[0003] In the prior art, there is a utility model with a publication number of CN213917200U, which relates to the field of processing of idle gear shafts, specifically a floating tooling clamp for processing idle gear shafts, including a tooling table and a clamp installed on the tooling table, wherein a shaft seat is fixedly installed on the tooling table, a seat hole for placing the idle gear shaft flat is provided on the shaft seat, and a through hole 1 with a hole diameter smaller than the hole diameter of the seat hole is provided on the bottom of the seat hole; a filling slider is slidably installed in the idle gear shaft, a through hole 2 for the drill bit to pass through is provided on the filling slider, and the filling slider is elastically connected to the bottom of the idle gear shaft. The beneficial effect is that the floating tooling clamp of the present application can clamp the idle gear shaft without causing deformation, thereby ensuring the processing accuracy of the drilling, and has good practicality, but during the processing, it is difficult to clamp and position gear shafts of different thicknesses or other shapes, which affects the processing of the equipment.

[0004] In order to solve the problem of difficulty in clamping and positioning gear shafts of different thicknesses or other shapes, the existing technology adopts the method of replacing the processing clamps. However, the new purchase of tooling clamps increases the user's economic expenditure, which in turn leads to the problem of inconvenient use of equipment and low processing efficiency.

By arranging the threaded rod, when in use, the threaded rod cooperates with the nut to position the clamp, which increases the usability of the device and reduces the difficulty of operating the device.
