[0002] Bearings are an indispensable key component in mechanical equipment. The main function of bearings is to support mechanical rotating bodies, reduce friction and rolling resistance, and thus reduce power loss. They are widely used in various mechanical equipment, and different types of bearings are suitable for different working environments and requirements.

[0003] The inner diameter boring production of bearings is a common bearing manufacturing process, which is mainly used to produce bearing parts with special geometric shapes. When boring the inner diameter, if the fixture is not firmly fixed to the bearing part to be processed, it may lead to insufficient processing accuracy, unqualified products, and even damage to the bearing parts. In addition, due to the fixing problem, the machining accuracy of the inner diameter of the bearing may be insufficient, resulting in excessive bearing clearance, affecting the rotation accuracy and service life of the bearing. Movement or vibration may also occur during the processing. Therefore, we propose a bearing boring inner diameter cutting positioning device to ensure the correct alignment and tight fixation of the fixture and the bearing parts. Utility Model Content
