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

Embodiment Construction

[0017] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0018] The present invention describes a precision machining process for a motor shaft, comprising the following steps:

[0019] 1) Rough machining by milling: First, the raw material is cut off a large amount of surplus material by milling, and processed into blanks by dividing them into different amounts, leaving a small amount of margin;

[0020] 2) Heat treatment: After that, put the blank into the furnace, slowly heat up for a period of time and reach below 450°C, and then heat it to about 700°C at a heating rate of 120°C per hour, and keep the temperature difference of each zone during the heating process in the furnace Not more than 30°C, keep warm in the furnace for 4-6 hours, and finall...

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...
