Detailed Description

The utility model is further described with reference to the following figures and examples.

Referring to fig. 1 to 5, a motor assembly structure includes a front end housing 2 and a rear end housing 3, a first protruding ring 21 is disposed on a lower end face of the front end housing 2, a second protruding ring 31 attached to the first protruding ring 21 is disposed on an upper end face of the rear end housing 3, flanges 4 are uniformly distributed on an outer side of the second protruding ring 31 along a circumference of the second protruding ring, and the flanges 4 are press-fitted on an upper end face of the first protruding ring 21. The assembled screw, gasket and nut are not needed, so that the cost of the product is greatly reduced; meanwhile, a plurality of workers do not need to respectively install screws, gaskets, nuts and fix the screws, and the operation can be completed by only one worker operating one machine, so that the high-efficiency and rapid production is achieved, and the production requirements are met.

Specifically, the outward flange of first bulge loop 21 is equipped with a plurality of bellying 22, bellying 22 with turn-ups 4 correspond mutually, through being equipped with bellying 22, can not only realize the location equipment with turn-ups 4, can further strengthen turn-ups 4's pressfitting stability moreover, increase with turn-ups 4's contact, improve the stability of equipment.

Specifically, a plurality of positioning lug seats 5 are correspondingly arranged on the first convex ring 21 and the second convex ring 31, positioning holes 51 are arranged on the positioning lug seats 5, and pins are longitudinally inserted into the two positioning holes 51 to realize rapid positioning.

During assembly:

attaching the front end cover 2 and the rear end cover 3 to each other, attaching the first convex ring 21 and the second convex ring 31 to each other, and inserting the pin into the positioning hole 51 when the positioning lug seats 5 correspond to each other;

and then the flanging 4 is bent upwards by a machine or a person, so that the flanging 4 is forced to be pressed on the upper end surface of the first convex ring 21 to realize fixation.

Furthermore, turn-ups 4 with the terminal surface of the laminating of first bulge loop 21 up end and the up end of first bulge loop 21 is equipped with unsmooth texture respectively, and unsmooth texture can strengthen the contact of turn-ups 4 with first bulge loop 21, but also realizes the effect of location, avoids 4 pressfittings of turn-ups to rock behind first bulge loop 21, guarantees stability.

Furthermore, an upward extending locking portion 211 is arranged on the upper end face of the first convex ring 21, a through groove is arranged on the turned-over edge 4, and the locking portion 211 is inserted into the through groove when the turned-over edge 4 is pressed on the upper end face of the first convex ring 21.
