Protective automatic dismounting device for electric vehicle motor

Abstract

The invention relates to the relevant field of electric vehicle power devices, and discloses a protective automatic dismounting device for an electric vehicle motor. The protective automatic dismounting device for the electric vehicle motor comprises a main box body, wherein a dismounting cavity with a forward opening is formed in the main box body; the lower side of the dismounting cavity communicates with a falling cavity; the outer side of the falling cavity communicates with an annular box body cavity formed in an annular mode; the side wall of the annular box body cavity is connected withan annular box body in a rotating fit manner; the tail end of the upper side of the side wall of the annular box body cavity outwards communicates with an annular inner gear ring cavity; the annularbox body drives a knocking block to rotate, so that uniform knocking at each part of the motor in the circumferential direction is realized; the motor is loosened relative to a hub; and the motor canbe favorably dismounted in the subsequent process; an impact block impacts the upper end surface of a motor main shaft under the effect of an impact spring; dismounting of the motor is realized; and the magnitude of accumulated force of the impact spring is changed by adjusting the position of an impact magnet, and the damage to the motor due to excessive dismounting force is avoided as much as possible.

Description

technical field [0001] The invention relates to the related field of electric vehicle power devices, in particular to a protective automatic disassembly device for electric vehicle motors. Background technique [0002] The current electric vehicle motor is usually disassembled and repaired manually. During the disassembly process of the motor, due to the high tightness of the motor assembly, if the motor is disassembled directly by impact, it is easy to cause damage to the motor. Usually, it is necessary to manually repair the motor. On the other hand, after knocking the motor, the work intensity of manual disassembly of the motor is still relatively high, and at the same time it is difficult to control the impact force, and it is easy to damage if the force is too high Insufficient strength of the motor will reduce work efficiency. Contents of the invention [0003] The object of the present invention is to provide an electric vehicle motor protective automatic disassemb...
