Abstract

The invention, which belongs to the field of manufacturing en electronic vacuum pump for en electric vehicle, relates to a clearance adjusting mechanism for a stator and a rotor of an electric vacuum pump. A motor base, a motor bracket, a rotary cylinder and a clearance adjusting head limiting base are fixedly connected to a base. The bottom of a motor main body is arranged on the motor base; an upper flange is arranged on the motor bracket; and the bottom of a mould is arranged on the motor bracket. A rotor is connected with a motor output shaft; a stator is arranged between the mould and the rotor; and an adjusting clearance is formed between the mould and the stator. A spring self-adjusting rod device is installed at one side of the mould and an error removing lever and a clearance adjusting lever are installed at the other side of the mould. The top of the rotary cylinder is in rotating connection with a clearance adjusting head having a tapered head part. The clearance adjusting mechanism has the following advantages: the structure is novel; the taper of the clearance adjusting head is used for measurement, so that the assembling processes of the stator and the rotor are simplified substantially; the operation is simple and convenient; the clearance can be adjusted; the consistency is high; the product quality is guaranteed; and the production take time is increased.

Description

technical field [0001] The invention belongs to the field of electronic vacuum pump manufacturing for electric vehicles, and is a tool for assembling a stator and a rotor on an electronic vacuum pump assembly line. Background technique [0002] At present, in the process of assembling the stator and rotor on the assembly line of the electronic vacuum pump, a tire is fixed on the main body of the vacuum pump. The fixing of the tire needs to be manually fixed with 3 M3 screws, and then the stator and rotor are put into the tire and assembled. Afterwards, the gap between the stator and the rotor is adjusted with the adjusting rods with ratchets on both sides of the tire, and the size of the gap is measured with a feeler gauge. SUMMARY OF THE INVENTION [0003] The invention provides an electric vacuum pump stator and rotor gap adjustment mechanism, so as to solve the problems that the gap adjustment between the stator and the rotor is cumbersome and affects the production rhy...
