Siheyuan starts from a better life

Chapter 238, start working

In the following time, Engineer Shen looked at the drawings and asked Jiang Yan without listening, and Jiang Yan took the trouble to look at the drawings and explain to him.

Jiang Yan also called Master Sun over from time to time to explain the difficulty of making parts and repairing parts to Engineer Shen.

Between this and that, the two of them communicated for almost half an hour, and there were quite a few problems on the blueprint.

The others were confused, but Wang Tianlai and Zhang Xiang, who were listening to Jiang Yan and Engineer Shen's exchange, benefited a lot and updated their views on the installation drawings.

The conversation was almost done. Jiang Yan said to Engineer Shen: "Mr. Shen, we are communicating in private about other situations. The most important thing now is to install this precision machine."

Hearing Jiang Yan's reminder, Engineer Shen, who was in the middle of a chat, came back to his senses.

Today I came here to learn how to install and repair precision forging machines, not to discuss too much.

He said a little embarrassedly: "I'll help you, and by the way, I'll also learn from Jiang Gong."

"Learn from each other, learn from each other."

After being humble, Jiang Yan began to direct the workers and engineers in the workshop to install the precision segment machine.

The workers chanted and lifted the base of the [-]-kilogram lathe. Under Jiang Yan's command, these bases were spliced ​​together like building blocks.

In less than half an hour, the machine base of the precision section machine was completely spliced ​​together.

Next, it needs to install other corresponding parts on it. The installation of these parts is the most important and the most delicate, so Jiang Yan can only do it himself.

Bearings: Support the existence of the entire mechanical system to ensure its efficient and safe operation.

Bearing is an indispensable element in mechanical system, it is an important guiding device, used to support mechanical device and coordinate its movement.Normally, the bearing has a load-bearing function, and its failure directly affects the safe operation of the transmission system.

The old shafts in this finishing machine had already been damaged, and the shafts made by the lathe were not up to standard. After rough machining, Sun Deshui led his two apprentices to finish machining.

Just to build a qualified axis like this, Sun Deshui took his two apprentices to work for three days.

Its precision and polishing degree are much higher than those installed on it before.

Under Jiang Yan's command, two workers carried the shaft and installed it into the corresponding slot according to Jiang Yan's command.

After installation, Wang Tianlai hurried forward with a ruler to measure whether the installation location was correct and whether it deviated from the planned track.

After the measurement, Wang Tianlai gave everyone a thumbs up. Seeing Wang Tianlai's thumbs up, Jiang Yan was relieved.

The installation of the shaft is the most important step of this machine. If this step is wrong, basically everything will go wrong.

The other parts were installed one after another under Jiang Yan's command.

"Wang Gong, turn this screw three times, and then return it half a turn."

"Shen Gong, Zhang Gong, and the screw installation are all in accordance with the standard I mentioned."

Seeing Wang Tianlai and the others tighten all the screws, Jiang Yan hurriedly opened his mouth.

"Isn't the tighter the better?" Wang Tianlai asked Jiang Yan puzzled.

Hearing Wang Tianlai's question, the other two engineers also looked at Jiang Yan with puzzled expressions.

Seeing their puzzled eyes, Jiang Yan explained the intention of Hans Guo's engineer to turn the screw back half a turn.

"It turns out that this is the reason. This country of Hans is indeed a country that can produce top-notch machine tools. It really has something unique. It even pays so much attention to installing a screw. Jiang Gong, if you don't tell us, we really don't know. You know, there are twists and turns."

The reason why Hans Country can own so many top machine tool companies and produce the world's top machine tools is inseparable from their accumulation in the field of heavy industry.
It is also directly related to the early research and development of high-end machine tools by Hans Country.Hansguo began to develop machine tools around the 19s, and by 80, his machine tool exports had already ranked first in the world.

Hansiguo Machine Tool not only developed earlier, but also has a layout for the entire industrial chain of the machine tool industry. A large number of domestic enterprises are directly or indirectly engaged in the machine tool industry, and a large amount of funds and manpower are also invested in scientific research.

Therefore, Hansland Machine Tool is not only leading the world, but also in the process of continuous development.

Even if the later generations of Zhonghua have the ability to develop machine tools, they are still inferior to Hans Country in the field of high-precision machine tools.

With the addition of various parts, the machine tool has gradually become fuller, and the speed of the three people can't help but increase.

Seeing that it was already noon, Jiang Yan and the others showed no intention of stopping.

Zhao Changche waved to his secretary, and the secretary ran over.

"Xiao Sun, go to the cafeteria and give them an extra meal." After saying this, he took out a few meal tickets from his pocket and handed them to him.

After seeing his secretary took over the meal ticket, Zhao Chang turned his head and said to Guo Jianjun: "Xiao Guo, you also go to help, bring all the food here, I will see if it will be finished in a while."

After Guo Jianjun responded, he followed Secretary Sun out.

"Jiang Gong, what should we install next?"

Engineer Shen asked Jiang Yan with a slightly excited tone.

As a technical idiot, he was very happy today. Not only did he see the detailed installation drawings of this fine segment machine, but he was also taught by Jiang Yan. He felt that he really made a lot of money this time. sent.

There are not many such precision machines in the country. He has been thinking about dismantling it for a long time, and this time he really got his wish.

When Jiang Yan heard Engineer Shen's question, he didn't say a word. He took a ruler and measured the installed machine again. The installation error was within his own design.

"Wang Gong, prepare the screw rod installation." Jiang Yan directly gave orders to Wang Tianlai who was standing there.

Hearing Jiang Yan's order, Wang Tianlai directly took the prepared screw and put it on the table.

The installation of the screw rod is another key point in the whole precision segment machine.It is related to the precision of the whole machine.

Although it is said that the screw has been tested to be accurate after manufacture, it is not certain that there will be no problems after the parts are installed.

To put it simply, although each part is within the allowable range of error calculated by itself, after assembling all the parts, this allowable error will be further expanded.

That is to say, the error tolerance of two parts can be superimposed or increase the tolerance. To a large extent, this tolerance affects the overall performance of the machine, and even affects the life and precision of the machine.

Fortunately, the newly produced parts were completed by Sun Deshui and his two apprentices, and the parts they produced were better than the original ones.

Therefore, the worst result that Jiang Yan had calculated did not appear here.

Therefore, a skilled worker plays an irreplaceable role in the repair of parts. Jiang Yan decided that he only needs to stay in this factory for one day, and the repair of parts must be handed over to Sun Deshui and the others.
