[0002] The compressor is a fluid machine whose main function is to compress low-pressure gas into high-pressure gas. It is the core component of the refrigeration system and is also widely used in other industrial fields. The transmission wheel plays an important role in the compressor. It is used to transmit motion and torque to ensure the normal operation of the compressor. Therefore, in the production process of the compressor, the transmission wheel is an important component. Its processing accuracy and quality directly affect the performance of the entire equipment.

[0003] After searching, the patent number "CN212635117U" mentioned in the text that "the utility model relates to the technical field of gear processing equipment, specifically a fixture for gear production, including a workbench, a chip dropping hole, a positioning ring, a clamping device and a clamp head. Two clamp heads are symmetrically arranged about the chip dropping hole. The clamp heads are arc-shaped structures. The inner walls of the clamp heads close to each other are provided with a positioning tooth group. The side of the clamp head close to the chip dropping hole is also welded and fixed with an arc-shaped support plate for supporting the gear." It clamps and supports the transmission wheel through the support plate of the arc structure, but in use, the transmission wheels have different sizes, and the fixed support plate cannot meet the diverse clamping requirements. At the same time, the transmission wheel has different process requirements in processing and production, and there will be different textures or pits on its surface, resulting in uneven force points during clamping, which makes the clamping force insufficient, which may cause the workpiece to shift during processing and affect the processing quality.

[0004] To this end, we provide a clamp for producing a transmission wheel to solve the above problems. Utility Model Content

[0028] Furthermore, the rotating assembly 22 includes a rotating seat 221 and a clamping and fixing platform 222. The rotating seat 221 is installed on the top of the lifting installation platform 212, and the top slot of the rotating seat 221 is connected to the clamping and fixing platform 222.

[0029] Furthermore, the positioning assembly 23 includes a positioning mounting platform 231 and a positioning pin rod 232. The top center screw of the clamping and fixing platform 222 is connected to the positioning mounting platform 231, and the top slot of the positioning mounting platform 231 is connected to the positioning pin rod 232. When the rotating wheel is placed on the clamping and fixing platform 222, the rotating wheel can be positioned by the positioning pin rod 232 to avoid the rotating wheel from being offset and causing unstable clamping.

[0030] Furthermore, the adjustment component 24 includes an electrically controlled adjustable telescopic rod 241 and an adjustable top plate 242.

Offset, the third step, after completing the placement of the rotating wheel, lower the clamping spindle 252, drive the clamping fixing plate 253 to fall onto the clamping fixing platform 222, and clamp and fix the transmission wheel of the compressor. The fourth step, during clamping, the clamping auxiliary spring 32 will first contact the rotating wheel, and the clamping auxiliary spring 32 will be forced to contract to clamp the transmission wheel.
