Tool for machining motor shell

The invention relates to the technical field of motor machining, in particular to a motor shell machining tool which comprises a containing frame, a clamping device and a cooling device, a limiting mechanism is arranged on the containing frame, a filling mechanism is connected to the limiting mechanism, and the cooling device comprises a blocking mechanism used for blocking cooling liquid. A cooling mechanism used for cooling the grinding position is installed on the blocking mechanism. The filling mechanism is matched with the blocking mechanism, in the motor shell end polishing process, internal and external synchronous blocking is carried out on the motor shell, cooling liquid is effectively blocked, the situation that follow-up assembly of the interior of the motor shell and the follow-up heat dissipation effect of the heat dissipation fins are affected due to the fact that the cooling liquid flows into the interior of the motor shell and the heat dissipation fins on the outer surface of the motor shell i
