Cover jacket used in motor rotor coating device of new energy automobile

Abstract

The invention discloses a cover jacket used in a motor rotor coating device of a new energy automobile. The cover jacket comprises a left cover jacket and a right cover jacket, wherein the structuresof the left cover jacket and the right cover jacket are the same; the left cover jacket comprises a round rod and a sleeve; one end of the sleeve is provided with a mounting hole for inserting one endof the round rod; the other end of the sleeve is provided with an insertion hole for inserting a rotating shaft of a motor rotor; after the round rod is inserted into the mounting hole, the round rodand the sleeve are fixedly connected through a plurality of screws; the apertures of the insertion holes in the left cover jacket and the right cover jacket are matched with the diameter of the rotating shaft of the motor rotor; and the end, which is not inserted into the mounting hole, of the round rod is fixedly connected with a baffle plate. According to the cover jacket used in the motor rotor coating device of the new energy automobile, in an epoxy powder electrostatic adsorption process of the motor rotor, a protection effect on the rotating shaft of the motor rotor can be achieved to prevent epoxy powder from being stuck to the end parts of the rotating shaft, and an effect of safely and steadily transporting the motor rotor can be also achieved. The cover jacket is long in servicelife and convenient to clean.

Description

technical field [0001] The invention relates to the technical field of new energy automobile motor production, in particular to a cover used in a new energy automobile motor rotor coating device. Background technique [0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines (including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles, etc.). New energy vehicles generally drive the vehicle through motors. Compared with traditional motors, the motors used in new energy vehicles need to meet a series of special design requirements. During the long-term driving of new energy vehicles, the motor loads a large current and the temperature of the body is very high. Therefore, higher requirements are put forward for the insulation performance of the new energy vehicle motor. The existing motor rotor will use the method of electrostatic adsorption of epoxy powder to add an insulating layer to the motor rotor, the...

Problems solved by technology

However, during the electrostatic adsorption process of the epoxy powder on the motor rotor, epoxy powder will also be adsorbed on the shafts at both ends of the motor rotor. It is necessary to design a special process to wipe the epoxy powder on the shafts at both ends of the motor rotor, which is time-consuming and laborious.
