Motor pressing device

Abstract

The invention discloses a motor press-fitting device which comprises a mould base, a positioning mechanism and a press-fitting mechanism, wherein the mould base comprises a horizontally arranged lower mould base, an upper mould base which is positioned above the lower mould base and is parallel with the lower mould base, and a guide column used for connecting the lower mould base and the upper mould base, wherein the upper mould base can move towards the lower mould base along the guide column under the action of ambient pressure; the positioning mechanism is arranged on the top of the lower mould base and used for positioning a motor component to be press-fitted; and the press-fitting mechanism is arranged at the bottom of the upper module seat, positioned above the positioning mechanism and used for press-fitting the to-be-press-fitted motor component between the press-fitting mechanism and the positioning mechanism by taking the positioning mechanism as a benchmark. According to the motor press-fitting device, the pressure on the motor component to be press-fitted is uniform, impact during press fitting is reduced, shaft noise and product rejection rate are effectively reduced, and production cost is saved.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a motor pressing device. Background technique [0002] Traditional motor press-fitting devices, such as figure 1 As shown, it is mainly composed of upper tooling 010 and lower tooling 020 which are independent of each other. During press-fitting, the lower tooling 020 is fixed on the base plate of the air press, and each assembly part 030 of the motor is correspondingly placed on the lower tooling 020 . see figure 2 , the motor components to be pressed are the lower end cover 031, the rotor assembly 032, the stator 033 and the upper end cover 034. After manual positioning, put the upper tooling 010 on the upper end cover 034, and start the air machine to press down on the upper tooling 010. Realize motor pressing. [0003] When the traditional motor pressing device is in use, the concentricity between the upper tooling 010, the lower tooling 020 and the motor assembly...

AI Technical Summary

Problems solved by technology

[0003] When the traditional motor pressing device is in use, the concentricity between the upper tooling 010, the lower tooling 020 and the motor assembly parts 030 is low, the force is uneven, and the positioning accuracy cannot be guaranteed, so that the air compressor passes through the upper tooling 010 When it acts on the stator, the impact force is relatively large, and the shaft noise caused by it is above 15000PPM

Therefore, the scrap rate of motor products assembled by traditional motor press-fitting devices is high, which greatly increases production costs
