Manufacturing Empire in the Valley

Chapter 70 Extremely Concealed and Deceptive Mechanical Failure
The vibration of the machine tool is generally caused by the loose ground piles, but Chen Jianguo himself knows maintenance techniques, so it is impossible to solve such a simple problem. Fang Dongping thought that the matter should not be so simple, so he hummed: "You Turn on the equipment, let's use the waste to test the machine on the spot."

Chen Jianguo agreed, and after turning on the power, he fixed the defective products produced before to the vise, and then controlled the milling cutter for punching and milling according to the standard operating procedure.

Fang Dongping and Niu Xiaoqiang observed carefully at the side. At the beginning, the machine was running smoothly, and there was no problem at all. However, when the gear was processed to the fifth tooth, the cutter head vibrated obviously.Because the vibration is very violent, it looks like a milling machine is shaking.

Niu Xiaoqiang lacked experience and failed to see the way.Like Chen Jianguo, the first thing he thought of was that the ground stakes of the milling machine were not fixed properly.

Fang Dongping was different. Seeing this scene, he tilted his head and listened for a while, then waved his hand to ask Chen Jianguo to turn off the machine, and said with a slight smile, "Xiao Chen, the cutter head was shaking just now, which caused the milling machine to shake together. The problem should be On the drive shaft, it's not that the mill isn't fastened."

Chen Jianguo asked in surprise, "Is it really a problem with the transmission shaft?"

Niu Xiaoqiang also looked at Fang Dongping with a puzzled look on his face, "Master, if there is a problem with the drive shaft, this milling machine should be reimbursed directly. How could it run so smoothly at the beginning?"

The transmission shaft is a precision part on the machine tool, and any problem will cause serious consequences.The most serious thing is that the mechanical transmission system of the entire machine tool is scrapped, which is not much different from the direct reimbursement of the machine tool.

Fang Dongping taught Niu Xiaoqiang earnestly: "Xiaoqiang, there are more mechanical equipment problems than you can imagine, and many of them are very confusing. You are too inexperienced in this area, so you are right. I am surprised by my conclusion, after I go back this time, I will talk to you about the various existing problems, you should first remember the experience gained by Master, and you will be able to achieve twice the result with half the effort in the actual operation in the future."

Master teaching apprentices is actually the inheritance of experience, especially in maintenance. What Niu Xiaoqiang currently lacks most is relevant experience. Hearing this, he nodded seriously: "Thank you, Master, I will definitely learn it. "

Although Chen Jianguo was surprised by Fang Dongping's conclusion, he still trusted Fang Dongping's technical level. He bent down to open the tool box, "I'll take the equipment apart and have a look."

Without much effort, Chen Jianguo removed the shell of the milling machine, exposing the mechanical transmission equipment inside.

Fang Dongping leaned over to watch carefully, and soon his face showed doubts, and he said to himself: "It's strange, I heard clearly just now, why can't I see the slightest problem now?"

When he said this, he raised his head and told Chen Jianguo: "Xiao Chen, you turn on the machine, I want to see what kind of moth it is."

Chen Jianguo warned: "You must not get too close, or you will be finished if you get caught by the machine."

"Don't worry, I'm not that reckless."

"Okay, I'll turn the machine on now."

Chen Jianguo turned on the power switch again, and under Fang Dongping's guidance, he controlled the operation of the equipment to a very slow level.

Fang Dongping looked at it intently, and after a while he suddenly burst out laughing: "Interesting, really interesting, I've lived for so many years, and I've never seen such tricks before!"

Chen Jianguo and Niu Xiaoqiang were watching from the sidelines just now, but they didn't see anything. Hearing Fang Dongping's laughter at this moment, both of them were at a loss.

Chen Jianguo couldn't help asking: "Fang Gong, what do you mean by that? What kind of deceitful trick?"

Fang Dongping did not answer, but pointed to a transmission gear: "You should observe this gear carefully and see if you can find any problems."

Hearing the sound, the two got closer, and huddled together to observe the transmission gear repeatedly.

Chen Jianguo looked over and over again, but still failed to find the problem.Niu Xiaoqiang was just like him at the beginning, getting more and more confused the more he looked at it, then he suddenly found something and couldn't help shouting: "The specification of this gear is wrong!"

After some observation, Niu Xiaoqiang finally discovered the problem.This transmission gear looks just the right size on the surface and fits perfectly on the drive shaft, but if you look closely, you will find that it has been stolen and someone replaced the original gear with another gear of the same size , resulting in the number of teeth not meeting the specifications of the entire transmission system.

If the number of teeth of the gear does not meet the specifications, there will be problems with the connection with other gears, which will affect the operation of the entire transmission system and eventually cause the vibration of the cutter head.

I have to say that this question is too hidden and extremely deceptive. If Fang Dongping hadn't been rich in experience and had identified the clue earlier by listening to the sound, it would be difficult to find the truth even if he checked it a hundred times.

After being reminded by Niu Xiaoqiang, Chen Jianguo finally understood.He quickly counted the number of teeth on the gear, and after confirming that it was correct, he immediately guessed who did it.I saw him slamming his fist on the machine table, turned his head and walked out, shouting angrily as he walked: "Good job Liu Yuejin! See if I don't beat you to death!"

Fang Dongping stretched out his hand to pull it, but Chen Jianguo's stubborn temper came out, he couldn't hold it back, so he could only verbally persuade him: "Xiao Chen, don't be messy, don't make too much noise!"

While talking, he grabbed Niu Xiaoqiang: "Go, let's try to persuade the fight!"

The two ran out behind Chen Jianguo. Chen Jianguo was tall and strong, and his speed was much faster than them. When they caught up, Chen Jianguo had already pinned the young man on the ground and punched him several times.

He beat and scolded: "How dare you slander me so much! If it wasn't for your sister's sake, I would have kicked you out a long time ago! I won't talk about the bad things in the past, but this time you did too much!" It’s too much! It’s hard to vent my hatred if I don’t teach you a good lesson!”

Chen Jianguo's wife was drying the clothes at first, but when she saw her husband beat her younger brother on the ground, she stopped drying the clothes and ran over crying, "Jianguo, if you have something to say, stop now If you hit it, you will break it!"

Fang Dongping and Niu Xiaoqiang also helped pull Chen Jianguo away after a lot of effort.Liu Yuejin had been beaten until his nose was bruised and his face was swollen. Two streams of blood flowed out from his nostrils, staining the clothes on his chest red.

Chen Jianguo took another kick, and then said bitterly: "Get lost! Never come back!"

His lover protected Liu Yuejin, shedding tears in anxiety: "Yuejin, what did you do? You made your brother-in-law so angry?"

　As always, please collect, ask for recommendation tickets, Weiyu smiles and implore everyone to support, thank you!
