The cam indexing plate is widely used in the manufacture of precision machinery, automotive parts, industrial robots and other fields. Its high precision and stability can meet the needs of various complex processing and assembly. The existing cam indexing plate still has defects and deficiencies in some aspects that need to be improved:

[0003] For example, a dust-proof roller cam indexing plate with application number: CN201721206813.1 includes a device box, four corners of the top of the device box are provided with top fixing holes, the top fixing holes are embedded in the device box, an operating table is provided at the front end of the device box, and the operating table is fixedly connected to the device box, a plurality of fixing holes are provided at the front end of the operating table, and the fixing holes are embedded in the operating table, a transmission shaft is provided at the middle position of the front end of the operating table, and the transmission shaft is embedded in the fixing holes of the operating table, and a top operating table is provided at the middle position of the top of the device box.

[0004] The indexing plates in the above documents are mostly operated by the meshing action between the cam and the roller. The cam and the roller are in contact for a long time, and the cam will be worn to a certain extent, so that the subsequent operation accuracy is not high. However, the existing cam and the driving component are mostly integrated. When the cam is worn out, the entire driving component needs to be replaced, and the steps are relatively cumbersome.
