Motor stator assembling apparatus and assembling method

Abstract

A motor stator assembling apparatus and an assembling method are disclosed. Current motor stator assembling has the following problems: a special press and a hoisting fixture are needed; costs are high; during a pressing process, coil damage or engine base rupture can be easily caused. The motor stator assembling apparatus comprises: a supporting bar, which is provided with a circle on a top; a disc-shaped base plate, which is vertically connected with the supporting bar; a supporting cylinder, which is connected with an outer ring of a seat board; a complex number of locating plates, which are connected with the supporting bar. A middle part of the base plate is connected with a lower end of the supporting bar. The locating plates are parallel to the base plate. The supporting cylinder is arranged above the base plate. The locating plates are arranged above the supporting cylinder. A screw hole, which is used for a screw joint hoisting ring, is arranged on an outer wall of the supporting cylinder. By using a technical scheme of the invention, the coil damage or the engine base rupture can be avoided. The motor stator assembling apparatus possesses a simple structure and good versatility. Equipment and tooling input is low. The special hoisting fixture does not need. The costs are low.

Description

technical field [0001] The invention relates to a motor stator assembly device and an assembly method. Background technique [0002] The motor stator is an important part of the motor. The stator consists of a base and a winding iron core. The base and the iron core adopt interference fit to ensure close contact between the two and increase heat conduction capacity. At the same time, ensure that the inner circle of the iron core is concentric with the notch circle of the machine base. And make the machine base and the iron core have no relative rotation. [0003] At present, the stator assembly method is usually to press the winding iron core into the frame on the press. Such as figure 1 , first hoist the base 2' into the lower workbench 1' of the press, and then use the special flip sling to hoist the winding stator core 3' into the guiding part of the machine base, and then hang the upper pressing cap 4' on the winding stator Iron core 3', and then start the press, s...

AI Technical Summary

Problems solved by technology

[0004] The existing motor stator assembly methods exist: first, a special press must be used, especially when the motor is large, the investment of the special press is very large

Second, each specification requires a special lifting fixture

The third is that due to the rough surface of the iron core, the friction with the machine base is relatively large, and it is easy to cause the punching plate to be skewed in the process of pressing down, resulting in damage to the coil or breakage of the machine base.
