[0001] The utility model relates to a tooling field, in particular to a clamping tooling for rapid face adjustment machining of end face holes of wheel parts. Background Art

[0002] Due to the advantages of pollution-free and low construction cost, wind power generation has developed rapidly in recent years.

[0003] In a wind power gearbox, for the machining of end face holes at both ends of a wheel part (such as a gear), generally, one end face hole is machined first, then the part is lifted and turned over, and then clamped again to machine the other end face hole. The operation is cumbersome and the efficiency is low. For parts produced in batches and with certain requirements for production accuracy, especially when there are relative position requirements for the holes on both sides, the existing machining methods are difficult to guarantee the accuracy.

The pressing plate presses the upper end face of the screw rod and the upper end face of the square block; on both sides of each square block, there is a set of combinations of sleeve, screw rod, double-headed stud, pressing plate, and nut respectively.

[0012] The height of the upper end face of the screw rod screwed into the screw hole opened on the upper end face of the sleeve is the same as the height of the upper end face of the square block.
