Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a clamp for processing sliding bearings. Background Art

[0002] Sliding bearings are bearings that work under sliding friction. They work smoothly, reliably and silently. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil without direct contact, which can greatly reduce friction loss and surface wear. The oil film also has a certain vibration absorption capacity. During the bearing processing process, grinding or polishing processes are required, and these processes require the use of fixtures for clamping and fixing.

[0003] Most existing clamps use cylinders to drive clamps to clamp bearings. However, the use of cylinders for clamping is not conducive to precise positioning during processing, and can easily cause the bearing body to deviate from the bottom of the processing device. Frequent adjustment of the cylinder operation is also required. Therefore, a clamp for sliding bearing processing is proposed to solve the above problems. Utility Model Content
