Siheyuan: I can simplify skills

The structure inside was something Xu Yang couldn't see from the data.The machine tools Xu Yang saw in the Mechanical Department's data room were often obsolete designs.Even this machine tool is still far behind the world's most advanced level.

Everyone looked serious.

This is the first time for everyone to see the internal structure of this precision imported equipment.

It will take a lot of time to fully understand the technology of this machine tool.Not to mention looking for faults inside.

The machine tool was slowly disassembled, and each step was photographed first to ensure that there would be no problems with subsequent installation.

The Superman in Xu Yang's memory, after just one glance, he can remember all the structures inside.After all, Xu Yang has independently designed many sets of equipment.Although the core uses the structure of Da Mao machine tools.But these internal structures are basically universal.

Although this machine tool is more advanced than the Da Mao machine tool, many transmission devices are similar in principle, so Xu Yang can still understand it.

After the machine tool is dismantled, each component is inspected.But no problem was found.

It was previously suspected that there was a problem with the servo motor, but during testing, the servo motor seemed to be normal.

"Reinstall it and process it to see where the problem is." Director Ma said.

Everyone started installing machine tools again.This time it is much slower than the disassembly speed.Always check the photos to make sure there are no problems during installation.

During disassembly, the parameters of each part have been measured, and the structure can be drawn later and even copied.Of course, it is difficult to say whether the accuracy can reach this level.

After reinstallation, perform a power-on test.But the problem still exists.

They can't find the problem, which gives these experts a headache.

Even if it is true that someone else has tampered with the machine tool and you can't find it, it's still in vain.

Chapter 112 Crazy liver skills

In the previous process, Xu Yang only wore ears and not a mouth.No comments were made.He has been observing silently from the sidelines.

He has completely digested the design of this machine tool, and the entire inside of the machine tool has been imprinted in Xu Yang's mind.It is indeed more precise to say that it is precise, and it is even more precise than the latest machine tool he designed.The upper limit of accuracy of machine tools is also much higher.

However, precision instruments and equipment also have their shortcomings. Maintenance costs are high and maintenance is difficult.Once a problem occurs, maintenance time will be relatively long.It is also very difficult to repair.Unlike the machine tools designed by Xu Yang himself, the maintenance is simple and the operation is stable, but the accuracy is a bit lacking.

If you were asked to design a similar machine tool, how would you combine the advantages of the two machine tools?

This is a question Xu Yang has been thinking about these days.

When the expert group encountered difficulties, Xu Yang finally spoke.

"Teacher, is it possible that the problem is caused by unstable fixtures? I looked at the fixtures for this kind of machine tool before, and they seem to be specially designed for general-purpose parts. When clamping special-shaped workpieces, they may not fit properly. .During the operation, affected by the vibration of the machine tool, the workpiece will deviate slightly, eventually leading to processing failure. On our assembly line, the fixtures of each machine tool are different and are completely designed based on your workpiece. This is to solve the problem of processing stability," Xu Yang said.

"Hey, it's really possible." Professor Wei said.

Director Ma immediately laughed and scolded: "You kid, have you discovered this problem a long time ago? Are you just raising it now?"

Xu Yang chuckled: "I didn't dare to confirm whether this was the problem before."

"I think you want to see the real internal structure of this imported machine tool. But that's good, this trip is not in vain." Director Ma said with a smile.

Xu Yang took advantage of the absence of Beigang's people to express his views.

The expert team returned to the Beigang Machine Tool Workshop and began to carefully inspect the fixtures on the machine tools.Sure enough, as Xu Yang said, there has been a certain degree of wear on the fixture.This shows that during the processing, the workpiece did indeed slide.

"Director Ding, the problem may have been found. During the break just now, Xiao Xu suggested that the processing failure may be caused by the unstable fixture. We just checked and found that the fixture is indeed somewhat worn, indicating that the workpiece may be damaged during the processing. There is a deviation. There is no problem with the machine tool. But the fixture is only suitable for general parts. If you want to process our batch of workpieces, you need to specially design the corresponding fixture. This is not difficult for Mr. Li," Director Ma said.

Li Zhiliang nodded: "The fixture is easy. I will design a set of fixtures immediately. Then I will test the machine."

At the request of factory director Ding Kecheng, the experts from the mechanical department still stayed at Beigang.Xu Yang writes and draws in his notebook every day.There was no delay when the time came.

"Xiao Xu, luckily I brought you here this time. Who would have thought that the problem would appear on the fixture? So, you technicians on the front line of production are the easiest to find problems. Let you stay in the steel rolling mill to complete it. The research topic is on the right track,” Director Ma said.

It would be a bit embarrassing if so many experts from the mechanical department came here and couldn't even find out the problem.

"Beigang's engineers were too rough and failed to discover such an obvious problem. We were also misled by them, always guessing the problem inside the machine tool, but ignored this simplest possibility," said Professor Wei.

"Actually, if I hadn't designed specifically for your batch of workpieces, I wouldn't have thought of the fixture problem. Because when designing this batch of machine tools, the accuracy didn't actually improve much. My purpose is to improve the machine tools. The stability enables our machine tools to reach the upper limit of accuracy. Therefore, I made an article on the fixture~" "Xu Yang said.

"This is the benefit of your background as a fitter. You have been a fitter yourself, so you naturally know where the most likely problems are during the machining process. That's why you have a special design of the clamp. Otherwise, it is really difficult to find this problem today. "Director Ma said.

Li Zhiliang, the chief engineer of Beigang, still had two brushes. He quickly designed the fixture and replaced the original fixture introduced into the machine tool.That batch of high-precision workpieces is then processed again.There were no problems with the products processed this time.But the quality is still not as good as that of steel rolling mills.Just qualified.

But there is no problem with the machine tool, but the operator still needs to improve his operating proficiency.

Beigang specially prepared a farewell banquet for the mechanical department team.

"Xiao Xu, what do you think of our Beigang?" Ding Kecheng asked.

"It's very good. The scale is much larger than our steel rolling mill. The factory building is also spacious and bright, and there are so many imported equipment." Xu Yang said.

"After you graduate from graduate school, are you interested in coming to us?" Ding Kecheng asked.

"I can't come. My staff has always been in the steel rolling mill, and I'm still getting paid at the steel rolling mill. If I want to run away, our Secretary Yang can chase me with a wrench and hammer me!" Xu Yang shook his head.

Everyone laughed.

Director Ma smiled and said: "Don't mention it, Lao Yang is really capable of doing such a thing."

Secretary Yang is a person who came down from the combat army. He has experienced hundreds of battles and is straight forward. Now that he is in the company, his temper has changed a lot, but when he is angry, his temper is still very bad.

"Don't be afraid, don't be afraid. As long as you are willing to come, I will definitely be able to get you over." Ding Kecheng said.

Xu Yang shook his head: "Everywhere I work, I contribute to the country. I'm used to the steel rolling mill, but I'm really not used to it in a different place."

On the way back, Professor Wei said to Xu Yang: "Your choice is right. Although Beigang is stronger than the rolling mill, it is not suitable for you. They already have a general manager. If you go there, I will be the vice president at most. The work is over. Li Zhiliang is only in his 40s, and it will take more than ten years before he retires. If you go to the steel rolling mill, with your ability, you will be the chief engineer in a few years."

Director Ma also agreed: "Besides, you have a relatively high degree of freedom in the steel rolling mill. Secretary Yang will probably support whatever you want to do. If you want to go to Beigang, you must first pass Li Zhiliang's test."

"The most important thing is that you are in the steel rolling mill, which is close to our school. You can come over and help us solve problems in the future." Professor Wei said with a smile.

"That's what Professor Wei said." Director Ma laughed.

"When I go back this time, I will definitely be scolded by Secretary Yang. If we solve the problem for them, our factory's orders will be reduced by half." Xu Yang said.

"You don't have to worry about this. If the workpieces processed by Beigang are not of high quality, we won't want them. If there are good parts, let me use the bad ones, unless there is something wrong with my brain." Director Ma said.

"If Beigang wants to produce high-quality products, it is estimated that the furniture will have to be redesigned," Xu Yang said.

"Why didn't you tell me in Beigang?" Professor Wei said.

Director Ma smiled: "If Xiao Xu had told her, Li Zhiliang might not only not be grateful, but would actually hold a grudge."

Professor Wei immediately understood what was going on: "Li Zhiliang is indeed not very broad-minded."

It wasn't that Xu Yang was worried about offending Li Zhiliang, but there was no need to say it.If Beigang cannot even solve this small problem, it will not be worthy of competing with the steel rolling mills for orders.At this time, Xu Yang did not need to be selfless.

When I returned to the steel rolling mill, Secretary Yang called me over.

"Boy, will you help our competitors?" Secretary Yang smiled and "criticized" Xu Yang.

"Director Ma and the others didn't notice this small problem at the time. If I didn't mention it, our Department of Mechanical Engineering would lose face. Moreover, the imported equipment that the country spent so much money on introduced cannot be wasted," Xu Yang said.

"You did a good job. Beigang is really useless. The imported equipment that they spent huge sums of money to introduce is a waste in their hands. It is better to give it to our factory." Secretary Yang was not without gloating.

Peers are enemies.The rolling mill and Beijing Steel compete in business.Previously, Beigang had always had an absolute advantage. Every time the ministry competed for interests, the steel rolling mill always suffered.

This time, it fell to Beigang to import equipment, and Secretary Yang was very unconvinced. After all, the results of the steel rolling mill during this year were much more impressive than those of Beigang.

But Beigang is much larger in scale, and the ministry often tilts its resources towards Beigang.The superiors thought it was normal, but Secretary Yang felt very angry.

Beigang finally stabilized the quality by redesigning the fixture.

But the quality is not [-]% controlled to be excellent. About [-]% of the products are qualified, and even about [-]% of the products are unqualified.

Compared with the [-]% high-quality products in the improved workshop of the rolling mill, the gap is huge.

Therefore, the rolling mills were hardly affected.

Xu Yang's influence in the steel rolling mill is naturally increasing day by day.

What surprised Xu Yang was that he had not seen Yu Haitang for so long after returning to the steel rolling mill.

I heard that Yu Haitang is studying hard and preparing to take the college entrance examination.It seemed that she still listened to Xu Yang's words.

The reason Yu Haitang didn't go to Xu Yang was because she felt a little inferior now and felt that she was not worthy of Xu Yang at all.Therefore, she wants to enter college and become a college student, so that she can be a good match for Xu Yang.

But what she didn't expect at all was that Xu Yang meant that she would have a chance to get into college when the college entrance examination resumed after the strong wind blew.Instead of taking the college entrance examination now.

The college entrance examination is still very difficult at this time.The number of enrollment in colleges and universities is relatively small and it is very difficult.Moreover, with strong winds, the college entrance examination will be cancelled.Even if Yu Haitang wanted to take the exam, he wouldn't have a chance.

After the college entrance examination is cancelled, the worker-peasant-soldier college student system will come into being.When the time comes, college students will not rely on exams, but on recommendations.

However, in the original drama, Yu Haitang was also an activist during the great turmoil.Maybe there will be an opportunity to become a worker, peasant, and soldier college student.

Xu Yang didn't know if Yu Haitang would change in this world, but for the time being, he didn't want to have anything to do with Yu Haitang.His main energy is still focused on research topics.He wants to complete his research project while the university is still open and strive to get a postgraduate diploma.

If the university is suspended, he, a graduate student, doesn’t know when he will be able to graduate.

Moreover, Professor Wei and others have never appeared in the original drama, and Xu Yang does not know whether they have been affected.

Professor Wei has already sent Xu Yang information on microelectronics and semiconductors.All materials are in foreign languages.

After Xu Yang got it, he felt like he had found a treasure.I spent a few days forgetting food and sleep to digest all this information.

Acquired several skills.

Microelectronics Engineering Skills: Getting Started (0/200)

Semiconductor Engineering Skills: Getting Started (0/200)

Integrated Circuit Skills: Getting Started (0/200)

Because they are self-taught skills, all these skills can be learned directly.

On that day, Xu Yang simplified semiconductor technology.

"?瀥?Ｄ?祧ku??�??yingＤ?祧kubi?LINQin褤?軣￠?

This one is quite simple.Diodes are found in radios.Xu Yang directly used a multimeter to measure the resistance on it.Skill proficiency keeps rising.

Xu Yang's understanding of semiconductor technology became more and more profound, and a large amount of semiconductor technology knowledge poured into Xu Yang's mind.This is the magic of the system. A lot of knowledge is not in the materials Xu Yang has read, and it can be created out of nothing.

And as the level increases, many technologies that transcend the times also enter Xu Yang's mind.

Before going to bed that night, Xu Yang had already mastered this skill.

The next day, Xu Yang used the energy points refreshed that day to simplify the inherited circuit skills.

"Integrated circuit skills are being simplified...Simplified successfully...Integrated circuit skills → Homemade simple integrated circuits."

Simple integrated circuits are actually very easy, not to mention the system gave Xu Yang a suggested integrated circuit.Xu Yang only needed to find a few very simple diodes to make an integrated circuit.

Xu Yang can directly obtain these parts from used radios.You can also buy it from regular stores.But the price will definitely be more expensive.
