This inspector, who looks like he is in his early thirties, should be a skilled worker recruited. He has several years of relevant work experience and has recorded the measured values ​​of these bearing inner holes one by one. He also measured the journal size of the turbine shaft and recorded the measured values.

Then there is calculation and calculate the interference amount based on these measured values. Li Tianfeng found that the inspector was quite skilled in his business and quickly settled the results. Then he selected a set of the most appropriate ones and made records of the turbine shaft and the corresponding bearing pairing.

Therefore, the pairing record form records the part number and the measured value of the inner hole of the bearing, and the measured value of the turbine shaft and the measured value of the shaft journal.

Looking at the entire process, Li Tianfeng nodded and thought to himself that the inspector's professional level is not bad. At the same time, Li Tianfeng is quite satisfied with Hu Xiao, the Minister of Human Resources Department. Hu Xiao is responsible and leads the recruitment of the personnel, and his quality and level are good.

After looking at the inspection area, Li Tianfeng saw that many parts of the "tfwz0...01" type turboshaft engine are being inspected and prepared before assembly.

In addition, in the component assembly area, Li Tianfeng saw that some parts had begun to be assembled. Li Tianfeng saw a middle-aged worker with a young worker assembling the turbine rotor, and couldn't help but walk over.

Seeing Li Tianfeng, the middle-aged worker took the initiative to say hello to Li Tianfeng: "Hello, Mr. Li."

Li Tianfeng nodded gently with a gentle smile and asked with concern: "Master, your surname?"

The middle-aged worker said: "Mr. Li, please don't have your surname Liu. This is my apprentice Xiao Chen."

Tianfeng Technology has gradually formed a tradition of teaching and helping. Young employees who have entered the factory usually sign a master-apprentice contract with an old employee who has been in the factory for more than one year, forming a situation where the old leads the new. After the half-year period expires, the apprentice can get started alone after the master is released, and gradually he can stand alone.

The apprentice Xiao Chen, led by Master Liu, is a new employee of the factory. He has only been two or three months since joining Tianfeng Technology Company. However, before joining Tianfeng Technology Company, Xiao Chen was an assembler in a large domestic aviation industry enterprise. He has three years of experience in aircraft assembly and is not a novice.

The two of them are more skillful in cooperation, and Master Liu will correct or remind them one by one without reservation.

Li Tianfeng asked with concern: "Master Liu, are there any problems during the assembly process?"

Master Liu is assembling the turbine rotor of the "tfwz001" type turbine shaft engine. To be specific, the turbine disc and turbine blades are now being assembled, and the turbine blades are loaded into the tongue and groove of the turbine disc. Then lock them with the lock plate.

Master Liu said: "Mr. Li, the assembly is quite smooth, but there is not much number of blades, so there is little room for choice. However, it can barely meet the assembly requirements."

Before installing the turbine blades on the turbine disc, the blades must be weighed, and the weight of each blade must be weighed one by one using high-precision electronic weighing. It is recorded and assembled according to the weight of the blades when assembling.

The tongue and groove of the turbine disc has a number. A small word "1" is marked with electrolytic mark next to the tongue and groove No. 1, and then according to the clock direction, it is 2, 3, 4, 5, etc. However, these tongue and grooves are no longer marked with numbers, and count them from the tongue and groove No. 1, to confirm it in the clock.

Li Tianfeng nodded. This is the truth. The number of turbine blades is really not large. Some of them are used for various tests. The number of turbine blades in the warehouse is only enough for two or three engines.

Li Tianfeng said: "It is temporary that the number of blades is not large. After our first verification machine, we will increase production investment. At that time, there will be more room for choice."

Master Liu said: "Mr. Li, our turbo disc is so beautiful. It adopts a new design structure. I have been working in assembly for twenty years and I have hardly seen such a turbo disc."

Li Tianfeng said: "This is a new design, the first in China. Such a turbine disk structure design is not only lighter in mass, but also more powerful."

While the two chatted, Master Liu did not stop working, and he seemed very skilled. Originally, Li Tianfeng was a little worried about whether chatting with him would affect the assembly quality, but seeing Master Liu so skillful, Li Tianfeng knew that his worries were unnecessary.

Master Liu numbered the blades according to their weight, and installed them into the turbine disc tenon one by one. The blades are naturally locked and the locked blades are used to lock the blades.

He held a small hammer in one hand and a small copper rod in the other hand, gently tapped it, bent the lock pieces, locked the blades, a turbine disc, and 31 lock pieces. Master Liu skillfully completed the skills of the two of them talking.

When Li Tianfeng saw such skillful techniques, he couldn't help but nodded secretly. Then he saw Master Liu start to use a special measuring tool to measure the amount of blade swing one by one, while Xiao Chen recorded it aside, recording the measured amount of blade swing one by one on the table.

What Li Tianfeng was also slightly surprised was that the blade swing was all qualified, and all passed at one time. Li Tianfeng, who knew the difficulty, was slightly surprised.

Generally speaking, suitable turbine blades should be selected before assembly. Experienced assembly masters can judge whether the swing volume of this blade will be qualified after locking the lock plate. Like Master Liu, it is very rare that all of them can be qualified at one time.

Li Tianfeng praised: "Master Liu, he is good at a good level and passes all at once."

Master Liu grinned, and Xiao Chen next to him said proudly: "Mr. Li, my master is a senior aviation engine assembly technician, and he has a lot of assembly skills."

Upon hearing this, Li Tianfeng was happy. He was actually a senior technician. This is a very amazing talent. Hu Xiao is not bad, and such talents have also been dug up.

Li Tianfeng knew that the assembly of aircraft engines is very different from the machining of parts. Part machining can clarify detailed process steps and reasonable process parameters in the process regulations. Workers operate according to the machining process regulations. As long as the worker's level is not too bad, they can generally process qualified parts. If the worker is more serious and has a higher level, they can also process excellent parts.

There is a little difference between the assembly of aircraft engines. The process regulations clearly define detailed process steps and reasonable process parameters are only one of them. In addition, the quality of assembly is largely related to the technical level of the assembly workers.

For example, the turbine blade assembly just now depends on the skillful assembly technology of workers to a large extent. If the technical level is not good, it may take half a day to assemble, and there may be repeated disassembly and repeated assembly to meet the technical requirements.

For the assembly workshop, every high-level technical worker is a huge wealth. The more wealth and the stronger the assembled aircraft engine, the higher the quality and smoother the entire assembly process.

Li Tianfeng praised Master Liu and watched the assembly of the combustion chamber in the component assembly area, and kept watching it for a long time.

The assembly of the combustion chamber is also very technical and has high assembly requirements. During the assembly process, workers have to constantly check the technical requirements of assembly parts such as jumping, coaxiality, etc. Once they fail, they may be disassembled and reinstalled.

The assembly of an aircraft engine is not just about assembling each part, but has many technical requirements, which require inspection and measurement while assembling.

In addition, the assembly of aircraft engines is also very detailed. Each assembly process has a large number of special record forms, which record the batch number and part number of each part assembled. In addition, the assembly sizes of each part must be recorded one by one.

Even after assembling a part, if there are technical requirements, such as jumping requirements, coaxiality requirements, etc., these technical requirements must be accurately recorded one by one.

There are many assembling of an aircraft engine, including various records, various information, and various forms. After the aircraft engine is assembled, these things must be sorted and bound into a book. Generally, each aircraft engine has a thick book.

These materials, plus the relevant materials for the test run, and these things are combined, they become the resume book of the aircraft engine and a thick book.

Each aircraft engine has its own thick resume book. Such resume book must be specially preserved and stored for more than 20 years. In the future, once the aircraft engine has quality problems, they can check these resume books.

Li Tianfeng has been watching the aircraft assembly workshop for a long time. The current assembly workshop has basically not been perfect, and there are only more than 100 employees, which is far from full-staffed, but it can already be assembled by aircraft engines.

When he came out of the assembly workshop, Li Tianfeng was full of expectations and was full of expectations for his first verification machine, looking forward to assembling it earlier and then conducting a series of test drive verifications.

………

In his office, Li Tianfeng sat down comfortably and took a sip of warm tea. Just now, Li Tianfeng went to the information room of the technical center.

The data room stores all kinds of design and technical data, has very high construction standards and is strictly confidential. It is thick electronic doors. It is entered with a combination of fingerprints and passwords. Li Tianfeng attaches great importance to the data room.

The data room not only has a large area, but also occupies three floors of the south building of the technical center. It can store a large amount of design and technical information in the future, and also has formulated very strict confidentiality measures.

Corresponding to the information room is the reading room. If necessary, technicians can check the information here. Although the confidentiality here is not so strict, there are many cameras installed and accessed by their own employee cards.

Li Tianfeng went to the information room in person, just now he inspected it himself, put forward some rectification and improvement opinions. Li Tianfeng dared not relax at all about confidentiality work.

After returning to his office, taking a sip of tea, and just about to turn on the computer, Liu Wei knocked on the door and came in.
