[0002] In the motor assembly production line, in order to facilitate the assembly of the motor in subsequent application scenarios, it is necessary to drill holes on the connecting ring of the motor casing. The existing drilling method is to drill holes in the outer wall of the casing one by one through a drill bit, which is too inefficient and the positions of each drilling cannot be accurately controlled. During the drilling process, coolant will be flushed to the drilling position through an external pipe to cool the drilling area. The heat generated by the drilling hole is high, and the coolant is flushed on it. In order to avoid interfering with the drilling operation, the coolant outlet is far away from the drilling position, which has a poor cooling effect on the casing drilling hole.
