Zusammenfassung: | The utility model relates to a processing positioning tool of motor brush rod, in particular to a comb teeth milling tool of motor brush rod, which solves the problems that the milling tool of the prior art has big positioning error, bad stability of assistant supporting and comparatively high reject ratio of processed brush rod. The utility model comprises a base which is provided with two milling bodies between which a supporting rod is arranged; one milling body is penetrated with a clamping screw; a supporting jaw rod is arranged between the supporting rod and the milling body; the other milling body is penetrated with a column positioning pin and a trimming positioning pin. The utility model solves the problem that the suspended part of the motor brush rod deforms in the processing so as to cause reduction to the processing precision, which changes the original positioning clamping bolt into the design of the column positioning pin and trimming positioning pin so as to improve the positioning precision o |
