Shearing tool for insulation paper of rotor slot of miniature motor

Abstract

The invention discloses a shearing tool for the insulation paper of a rotor slot of a miniature motor. The shearing tool comprises a tool holder and a tool bit. The tool bit has a zigzag structure with three teeth which comprises a middle entire tooth with cutting edges and two half teeth on the two sides of the entire tooth, wherein the two half teeth are symmetrical about the middle entire tooth; the inner sides of the two half teeth are provided with a cutting edge respectively; and the width of the tooth root of the entire tooth is equal to the length of a sandwiched arc of an outer circle between two adjacent slots of a rotor. When the shearing tool for the insulation paper of the rotor slot of the miniature motor is used, the two half teeth of the tool are arranged between the insulation paper and the outer circle of a rotor core respectively, the middle entire tooth is arranged on the outer circle of the rotor core, the tool holder applies a thrust to the tool, and the tool bit moves forwards along the outer circle of the rotor core to cut off the insulation paper at the two ends of the rotor slot at the same time. Compared with the prior art, the shearing tool shortens process time for removing the insulation paper of the rotor slot of the miniature motor to be 1 / 3 of original process time, improves labor productivity and decreases the production cost of an enterprise.

Description

technical field [0001] The invention relates to an auxiliary production equipment for a micro-motor, in particular to a shearing tool for removing insulating paper from a slot of a micro-motor rotor. Background technique [0002] At present, after the winding of the micromotor rotor is completed, the insulating paper covering the outer surface of the rotor core must be removed. The removal method in the prior art is to cut the insulating paper from the middle with scissors, and then separate the insulating paper along the left and right walls of the groove. Cut off the insulating paper. According to this method, workers must repeat the operation three times to remove a slot of insulating paper. Therefore, the traditional removal method has the disadvantages of high labor intensity, low labor efficiency and high production cost. Contents of the invention [0003] The purpose of the present invention is to provide a micro motor rotor slot insulating paper shearing tool, whic...
