[0002] With the development of industrial manufacturing, the requirements for the processing accuracy and efficiency of bearings are getting higher and higher. In the mechanical processing process, chamfering of bearings is one of the common processes to improve the quality and assembly performance of bearings. Traditional chamfering methods usually use manual tools or mechanical chamfering machines. These methods have problems such as complex operation and low efficiency. In order to meet the needs of modern industry for high efficiency and high quality, pneumatic chamfering machines came into being. Existing pneumatic chamfering machines usually consist of a driving mechanism and a clamping mechanism. When in use, the bearing to be processed is fixed and clamped by the clamping mechanism, and the driving mechanism is used to drive the tool for chamfering. However, when clamping the bearing, the existing pneumatic chamfering machine often takes a long time to adjust and fix the bearing, which not only affects the processing efficiency, but also may cause inaccurate positioning of the workpiece and affect the chamfering quality. In order to solve the shortcomings of the existing technology, we propose a quick clamping pneumatic chamfering machine. Utility Model Content
