Description

Technical Field

[0002] The drive shaft is a high-speed, low-support rotating body, mainly used to transmit the power generated by the motor to the reducer and other equipment. Due to the high-speed rotation of the drive shaft and the large output force, the shaft is required to have a certain hardness. Traditional drive shafts are usually made of metal, but with the development of technology, carbon fiber drive shafts have appeared. The shaft tube part of the carbon fiber drive shaft will have burrs on the outside after production, and it needs to be ground to make the outside smooth, and then connected with the telescopic sleeve and the universal joint to form a complete drive shaft. The drive shaft is an important component for transmitting power in the automobile transmission system.

[0003] For example, a Chinese patent document with publication number CN213225453U discloses a flash grinding device for transmission shaft processing, which records that "it includes a circular frame, a first electric telescopic rod is fixedly connected to the top of the circular frame, and the protruding end of the first electric telescopic rod extends into the circular frame and is fixedly installed with a mounting seat, a driving motor is fixedly installed at the bottom of the mounting seat, a non-slip hard rubber block is fixedly connected to the bottom end of the output shaft of the driving motor, a rotating shaft rotatably mounted on the inner wall of the bottom of the circular frame is provided below the protective hard rubber block, and a fixed plate is fixedly sleeved on the rotating shaft". Through the cooperation of the driving motor and the telescopic rod, the device can quickly remove the workpiece sleeve that needs to be replaced, and automatically complete the grinding of the outer side of the transmission shaft tube workpiece, with high flash and burr grinding efficiency.

This flash grinding device for processing a transmission shaft solves the problems of low processing efficiency and inconvenience in clamping transmission shafts of different specifications in existing flash grinding devices for processing transmission shafts.
