Description

technical field [0001] The invention relates to the field of motor devices, in particular to a precision machining process for a motor shaft. Background technique [0002] When the motor is in use, it must obtain a large output torque on the shaft, and the space outside the shaft is strictly limited. It is difficult to set the arm in the slender space, which reduces the mechanical efficiency. At the same time, the motor shaft needs to be perforated because of the lead wire. The bearing capacity is relatively weak, which weakens the mechanical strength. In addition, in the production process, due to the need to use external machinery to perform operations such as milling, cutting, and drilling on the motor shaft, it is easy to affect the strength of the motor shaft, thereby destroying the internal structure of the motor shaft and shortening the use of the motor shaft. life. In addition, in the process of processing, various parts that are difficult to process are often enco...

Problems solved by technology

[0002] When the motor is in use, it must obtain a large output torque on the shaft, and the space outside the shaft is strictly limited. It is difficult to set the arm in the slender space, which reduces the mechanical efficiency. At the same time, the motor shaft needs to be perforated because of the lead wire. The bearing capacity is relatively weak, which weakens the mechanical strength

In addition, in the production process, due to the need to use external machinery to perform operations such as milling, cutting, and drilling on the motor shaft, it is easy to affect the strength of the motor shaft, thereby destroying the internal structure of the motor shaft and shortening the use of the motor shaft. life

In addition, in the process of processing, various parts that are difficult to process are often encountered, thereby reducing the processing efficiency, wasting a lot of manpower and material resources, and the work effect is poor.
