Abstract

Provided is a structure for fixing magnetic tiles to a motor housing. The structure comprises a housing assembly. The housing assembly comprises a cylindrical housing and four magnetic tiles fixedly arranged on the inner wall of the housing and uniformly distributed. Inwardly-recessed ports are formed between every two magnetic tiles such that four inwardly-recessed ports are provided totally. Four clamp springs are also included and disposed in the four inwardly-recessed ports respectively. The clamp springs are formed by processing thin spring steel plates. The two sides of each clamp spring are provided with bent edges in small reel shapes. After the clamp springs are pressed into the inwardly-recessed ports and assembled with the magnetic tiles, the bent edges in small reel shapes on the two sides of each clamp spring and the magnetic tiles are pressed. Therefore, the bent edges in small reel shapes are deformed by force and the clamp springs are in compacted states and simultaneously generate force towards two sides. As a result, the magnetic tiles are fixed. The clamp springs are produced by 62Mn thin steel plates and have thicknesses of 0.25mm. The structure has beneficial effects that the magnetic tiles are reliably fixed by the clamp springs, that an assembling seat is cancelled and size change is easy to monitor, that glue can be clearly cleaned in order that an assembling clamp is prevented from being tightly pasted, and that timely detection can be achieved and batch scrap is prevented.

Description

A kind of motor chassis is magnetic shoe structure fixedly

Technical field

The utility model is a kind of fixedly magnetic shoe structure, and particularly the fixing magnetic shoe structure of a kind of motor chassis, belongs to motor part technical field.

Background technology

The conventional casing of motor and the assembling of magnetic shoe are to adopt fixedly magnetic shoe mode of alone glue, after having put casing on the skin glue, pack magnetic shoe into, put again baking oven baking into, glue reaches and solidifies rear fixedly magnetic shoe, this mode is simple in structure, easy to operate, but shortcoming is because magnetic shoe is without pre-fixing power, casing have enough to meet the need again or bake process in magnetic shoe position be easily shifted; After magnetic shoe assembling, must fix with assembling stand, assembling stand quantity required is large, is difficult for monitoring management; Magnetic shoe surface surplus glue is difficult for removing, and easily clings assembling stand, after taking-up, easily scraps; After must waiting until drying adhesive after magnetic shoe assembling, could detect its quality state, if defective, can cause in batches and scrap.

Utility model content

The purpose of this utility model is for said motor casing fixedly in the prior art of magnetic shoe structure, exist magnetic shoe fixing unreliable, easily displacement, use assembling stand, the variation of inconvenience monitored size, glue is clean unclean, easily sticky dead assembling stand, can not detect in time, can cause the defect of scrapping in batches, fixedly magnetic shoe structure of a kind of motor chassis is provided, can reach magnetic shoe fixing reliable, unshift, cancelled assembling stand, easily monitored size variation, glue can clean totally, prevent sticky dead assembling jig, can detect in time, can not cause the object of scrapping in batches.

The technical scheme that the utility model is taked is to achieve these goals: a kind of motor chassis is magnetic shoe structure fixedly, comprise case component, described case component comprises casing and 4 magnetic shoes, described casing is cylindrical shape, described 4 magnetic shoes are fixedly installed on casing inner wall, are evenly distributed, magnetic shoe is arranged near case component bottom 4 one sides, between every 2 magnetic shoes, forms inner recess, has 4 inner recess;

Also comprise 4 jump rings, described 4 jump rings are separately positioned in 4 inner recess; Jump ring is that thin steel spring plate processes, and the both sides of jump ring are rouleau tubular flanging; Described jump ring is arranged near case component bottom one side, and jump ring front end is inwardly brings shape together, is convenient to assembling; When jump ring be pressed into inner recess, with after magnetic shoe assembling coordinates, the rouleau tubular flanging of jump ring both sides and magnetic shoe push, rouleau tubular flanging stress deformation, jump ring is compacted state, produces the crowded power to both sides simultaneously, and the magnetic shoe of both sides is fixed.

Described jump ring is made by 65Mn sheet metal, and its thickness is 0.25mm.

Compared with prior art, the beneficial effects of the utility model are:

(1) magnetic shoe is fixing reliable: developed fixedly jump ring of a kind of casing magnetic shoe, adopt case component, the jump ring assembly structure of new structure, utilize jump ring that magnetic shoe is pre-fixed in casing, play the effect that prevents that magnetic shoe is shifted in taking-up, taking and placing, turnover, handling process;

(2) cancel assembling stand, only used a set of assembling jig, easily monitored the variation of fixture location dimension;

(3) case component surface surplus glue can clean totally, prevents from gluing dead assembling jig and causes and scrap;

(4) after case component assembling, can detect in time, monitor its quality state, avoid causing the situation of scrapping in batches.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.

If Fig. 1-1 is to as shown in Fig. 2-3, a kind of motor chassis is magnetic shoe structure fixedly, comprise case component, described case component comprises casing 1 and 4 magnetic shoes 2, and described casing 1 is cylindrical shape, and described 4 magnetic shoes 2 are fixedly installed on casing 1 inwall, are evenly distributed, magnetic shoe is arranged near case component bottom 4 one sides, between every 2 magnetic shoes 2, form inner recess, have 4 inner recess, it is characterized in that:

Also comprise 4 jump rings 3, described 4 jump rings 3 are separately positioned in 4 inner recess; Jump ring 3 processes for thin steel spring plate, and the both sides of jump ring are rouleau tubular flanging; Described jump ring 3 is arranged near case component bottom 4 one sides, and jump ring front end 301 is inwardly brings shape together, is convenient to assembling; After jump ring 3 is pressed into inner recess, coordinates with magnetic shoe 2 assembling, the rouleau tubular flanging of jump ring 3 both sides pushes with magnetic shoe 2, rouleau tubular flanging stress deformation, and jump ring 3 is compacted state, produces the crowded power to both sides simultaneously, and the magnetic shoe 2 of both sides is fixed.

Described jump ring 3 is made by 65Mn sheet metal, and its thickness is 0.25mm.

Assembling process: first four magnetic shoes 2 (are not shown in figure by fixture, this fixture is that routine techniques repeats no more) location, put into casing 1, put into again four jump rings 3, by fixture, jump ring 3 is press-fitted in case component, after being press-fitted, jump ring 2 is magnetic shoe 2 positions fixedly, and now operator can take out product from assembling jig and detects in time.

Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out within the scope of technical solutions of the utility model and replacing all should be included in protection range of the present utility model.
