Transmission friction plate tooth profile aligning and centering tool

The utility model relates to a transmission friction plate tooth profile aligning and centering tool which comprises a positioning frame, a round bar and a conical block, one end of the round bar is vertically connected to the positioning frame, the other end of the round bar is provided with the conical block, the middle of the positioning frame is arranged on a clutch shaft in a sleeved mode, and the conical block is arranged on the middle of the positioning frame. The clutch shaft is vertically arranged in the middle of the clutch outer hub, a friction plate is assembled on the clutch outer hub, and the round bar and the conical block abut against inner teeth of the friction plate. The tool replaces a traditional method for manually shifting and aligning the friction plates, centering of the friction plates is achieved through the contact force action of the round bar in the loading process and during rotation, the effect can be guaranteed, the consistency is good, follow-up friction plate tooth-shaped mat
