[0002] The bushing plays a key role in the transmission of the machine, ensuring that there is no reverse offset due to vibration and that the middle part of the bushing passes through the shaft end, thereby ensuring the stable operation of the machine.

[0003] Usually, in the production process of bushings, the raw materials are cut into several bushings by cutting, cutting devices, etc., and the bushings generally need to be installed manually when they are sleeved on the transmission rod. Usually, the edges of the inner walls of the bushings are not chamfered after processing. Therefore, for bushings and transmission rods with high precision requirements, it is necessary to accurately align the inner wall of the bushing with the outer wall of the transmission rod before threading them together during manual sleeve connection. Bushings that are not chamfered are less efficient in alignment, and there are few traditional bushing raw material cutting devices that can complete cutting and chamfering at one time. For this reason, I proposed a bushing raw material cutting device. Utility Model Content
