[0002] The machining of bearing seats refers to the process of changing the external dimensions or performance of bearing seats through one or more mechanical devices. The main machining methods of bearing seats include: turning, where the bearing seat rotates on a lathe and the turning tool moves linearly or curvilinearly in a plane for cutting; milling, where the milling cutter of a milling machine rotates as the main motion and the movement of the bearing seat or the milling cutter is the feed motion; drilling, where a drill bit is used to machine holes in solid materials; and grinding, where a grinding tool processes the surface of the bearing seat at a high linear speed, enabling high precision and low surface roughness. Machining has the following important characteristics: high precision, capable of achieving precision at the micron or even nanometer level to meet the manufacturing requirements of high-precision parts; high efficiency, with the use of automation and numerical control technology to significantly improve production efficiency; repeatability, where the same machining process and parameters can ensure the consistency and interchangeability of parts.
[0003] In some existing bearing seat machining fixtures, when machining a bearing seat, the bearing seat is placed on the fixture, and then the bidirectional lead screw is rotated by a rotating pulley, and the bidirectional lead screw drives the clamping blocks to move towards each other to clamp the bearing seat.
