Description

Technical Field

[0001] The utility model relates to the technical field of vehicle front transmission shaft processing, in particular to a vehicle front transmission shaft fixing processing device. Background Art

[0002] In the current machinery manufacturing industry, the transmission shaft is the core component of vehicle power transmission. Its processing accuracy and quality are directly related to the performance and safety of the vehicle. The transmission shaft is one of the main parts of the machine parts. All transmission parts that perform rotary motion must be installed on the transmission shaft to transmit motion and power. The main function of the transmission shaft is to transmit moment and torque. During the processing of the transmission shaft, it is usually necessary to use a fixture to fix the transmission shaft for subsequent processing operations;

[0003] However, this fixing method has obvious shortcomings. First, when the other side of the drive shaft needs to be processed, the drive shaft must be removed from the fixture and then re-fixed. This process is cumbersome and time-consuming, which seriously affects the processing efficiency. Secondly, multiple loading and unloading operations not only increase the labor intensity of workers, but may also cause damage to the drive shaft, affecting its processing accuracy and service life. Therefore, we proposed a fixing processing device for the front drive shaft of the vehicle to solve the above problems. Utility Model Content
