Siheyuan: Starting from a fitter

Chapter 14 Lathes and Measurement Standards

"Master, what's going on with the German Emmergo machine tool in the utility room?" Li Guocheng has been keeping an eye on it for a long time.

"Hey, it's an old antique from the 30s. It was repaired repeatedly, and it was completely ruined the year before last. It can't be repaired," Zhang Tou said regretfully.

"Master, I want to try Xiu Xiu, do you think it can be done?" Li Guocheng finally showed his fox tail.

"You have to think about it, the technical department has written a 'death notice'. Do you know what this means?"

"I recently read some materials about machine tools in the library, and I want to learn from them. Anyway, they are broken, so they can be reused." The lie came out without blushing at all.

"Well, studying... is supposed to be encouraged, but the tasks you undertake must be completed. If you use your spare time to study, I passed it here. I will ask the director for his opinion later. After all, the broken machine tool is also It is a national asset and any operation requires approval." The master seizes every opportunity to teach his apprentice.

"Don't worry, we will ensure that we complete our daily tasks," Li Guoliang said with a serious salute.

"Master, you must remember to ask the director," Li Guocheng urged eagerly.

"Don't worry, I'll get back to you at noon," Zhang Tou said with disgust.

"Master is mighty", the flattery is given.

"Go away", Zhang Tou showed even more disgust.

In order to "learn", Li Guocheng speeded up the processing slightly, and finally waited for the master's affirmative reply at noon.After completing the tasks undertaken, I dived into the utility room, cleared a space, and prepared to dismantle the machine tool.

First, I looked around the machine tool. It was a standard horizontal two-axis machine tool. The model number was so worn that I could not see clearly, and the motor had also been removed.

Shaking the joystick works fine from top to bottom, with only a less noticeable stutter.Shake the vertical rocker, the start is okay, when it travels 50mm, there is a very obvious freeze, when it travels to almost 100mm, the cutter head bracket has obvious nodding movements up and down, left and right, and the dual-axis To "upgrade to four-axis", which is already "beyond" the world's most advanced machine tool, Li Guocheng had a bad taste in his heart.

"The guide rails were so worn that they were sentenced to 'death'. The level of the previous operator was so high. In my opinion, ordinary fitters can't even complete rough machining with this machine tool," Li Guocheng thought to himself.

No wonder the masters in the workshop have fixed lathes. They are more concerned about protecting their own wives than they are about protecting their own wives. They scrub them morning and night, lubricate them on time, and never lend them out. They are usually so protective that laypeople don't understand.Now I understand that most of the machine tools in the steel rolling mill were left over before liberation, with only a small amount of support from the Far East Empire, and even fewer domestically produced 18 Arhat machine tools. It is a completely multinational machine tool exhibition hall.

This is the great thing about our older generation of fitter masters. Everyone is very familiar with their own machine. They know where to drive and how to operate it. Whether to speed up the cutting or slow down the cutting, they are completely clear about it. Feel in control.

You can imagine what kind of magical skills a level 8 fitter is. He is really good at rubbing Feifei and Hanghang with his hands. Then he can understand the reason why the number of level 8 fitters in the entire steel rolling mill can be counted with one hand, and there are only more than 50 people in BJ. At the same time, he also understands why the steel rolling mill has The factory is a bureau-level administrative level.

I have a general understanding of the characteristics of this old machine tool. It is getting late and I don’t dare to dismantle it directly. I plan to go to the technical department tomorrow to find out if there is any relevant information.If you go by yourself, no one will take care of you, and you will have to trouble the master.

At the same time, it has become clear that the guide rail is seriously worn. Without a level measuring tool, the 1.5-meter-long guide rail can only be maintained roughly, which is not what I want. My main goal is to use the maintenance of this machine tool to explore my own processing capabilities. This will lay the foundation for future development and help you plan your own route.

Of course, it is also to show one's strength to the factory, so as to have the opportunity to access more technical information, accelerate the improvement of technical capabilities, and expand one's influence, so as to gain a status in the scientific and technological field before reform, help future development be more stable, and reduce labor costs. resistance.As a later celebrity said, "When I succeed, I will be surrounded by good people."

After a speechless night, he made his request to the master the next day at work. The master thought about it and asked him to wait where he was before walking to the director's office.Walked out in ten minutes.

"Let's go, the director has called the head of the technical department, we can go directly to Mr. Wang." This is the benefit of having a master. How important is a master who thinks about you, foresight, and "wiping your ass" , to help you expand your network.

On the way, Li Guocheng quietly took out a pack of Hongtashan and a pack of Zhonghua from his satchel, showed it to the master, then directly put his hand into the two pockets of the master's jacket, one pack on each side. It was not obvious and easy to operate. Zuo Zhonghua , Right Tower Mountain.

He opened his head, was stunned for a moment, looked at Li Guocheng, his eyes changed from surprise to relief, shook his head and smiled, but said nothing.

Li Guocheng responded with an understanding smile.

Entering Room 103 on the first floor of the office building, there are two rooms. The large room is more than 100 square meters. There are more than 20 tables. The tabletop is supported by a drawing board. I originally thought that such drawing boards appeared after the 80s and 90s. Unexpectedly It was invented in the 60s.The walls were lined with metal filing cabinets.

"Wait here," Zhang Tou ordered. After saying hello to everyone, he entered the small room. The master is very popular.A few minutes later, two people came out of the small room. The first one was a middle-aged man in his 40s. He wore glasses and had a friendly face.Of course the one at the back is Zhangtou.

"Wang Gong, please help receive Master Zhang and try your best to meet the needs." He said and Li Guocheng smiled and nodded, shook hands with Zhang Tou and entered the inner room.

"Master Zhang, what do you need?" Wang Gong said politely with a chuckle.

"Hello, Mr. Wang, this is my apprentice Li Guocheng. He wants to learn some principles and structures of KT200 and see if you have any relevant information here. In addition, he also wants to see the measurement standard parts of our factory. Please bear with me." Very naturally, he gently put Hongtashan into Wang Gong's open drawer.Wang Gong just smiled and reciprocated, and everyone understood it tacitly.

"It's not important information. Just wait a minute and I'll give it to you."

After flipping through the minutes on each file cabinet, a file bag was brought out in less than 5 minutes, which fully reflects the data archiving capabilities of major domestic manufacturers.

"Come on, Mr. Zhang, please register here. Just come back and sign after reading." He handed the notepad he brought with him to Mr. Zhang. Li Guocheng was very discerning and registered according to the above record pattern. He respectfully handed it to Zhang Tou, who signed it and handed it back to Wang Gong.Gong Wang looked at it.

"Not bad." He glanced at Li Guocheng first, then looked at Zhang Tou with a smile and nodded.

"Come on, the standard parts are in the warehouse."

A red wooden box with copper corner guards was gently placed by Wang Gong on a large solid wood table near the door. He gently opened the lid and saw red silk cloth. There was a sponge on the lid. When he opened the silk cloth, Four standard cubic metal blocks of 1mm, 5mm, 10mm and 20mm are embedded on the red silk cloth.It seems that now everyone does not have the awareness of constant temperature and humidity protection.

"Master Zhang, you can only look, not touch. You need to wear gloves and handle with care when measuring," Gong Wang said seriously.

"Understood, Guocheng, you have to be careful," Zhang Gong also said seriously.

"Yeah", Li Guocheng's eyes were all standard blocks at this time.

Staring around the standard block, Li Guocheng slowly constructed a standard block of the same size in his mind. He pinched his index finger with his thumb to check the length. After several times, the exposed length of his index finger was actually faster than the standard block. Exactly the same.Of course, others can't see this, only Li Guocheng himself is very sure.

I remember that I could build blueprints in my mind before, and then accurately map them to the workpiece, and I felt that I was abnormal enough.But since he woke up the day before yesterday, Li Guocheng found that his sense of distance had become even more abnormal. He could actually use the vernier caliper in the workshop to calibrate it. Considering that the vernier caliper in the workshop had been used for too long and the error was too large, he thought of using standard parts to calibrate it. .

Now Li Guocheng is more in awe of the techniques in the secret realm, and the things from his ancestors feel like a more advanced technological civilization.Just like traditional Chinese medicine, some old traditional Chinese medicine doctors can diagnose the patient's condition by taking the pulse, which can be called human CT.

Zhang Tou and Wang Gong were confused by Li Guocheng. When Li Guocheng stood up and backed away, the two looked at each other, ranging from confusion to weirdness, and then laughed.

"You're an interesting apprentice," Wang Gong said with a playful smile.

"I didn't expect that this kid, who has always been steady, actually knows how to joke today," Zhang Tou said awkwardly.

Li Guocheng didn't explain, and couldn't explain, just followed with a smirk.

On the way, Zhang Tou asked seriously: "Tell me what's going on." Zhang Tou knew Li Guocheng well and would not be easily fooled.

"I don't know why. I have been sensitive to distance since I was a child, so I wanted to try to look at standard parts, hoping to strengthen this feeling," Li Guocheng said speciously.

"You should control it yourself. It's best not to do such nonsense in the future." He obviously didn't believe it, but he didn't delve into it.

"I know, master, I won't do it again." Instantly, my back was covered in sweat, knowing that my master was reminding me.
