Abstract

The invention discloses an energy-saving and efficient motor housing with high positioning accuracy. The motor housing comprises an upper shell and a lower shell, wherein positioning marks are arranged on the upper shell and/or the lower shell; pawls are arranged at the inner sides of the side wall surfaces of the upper shell and the lower shell and are punched from outer circular rings on the side wall surfaces; and the inner circumferences of the outer circular rings are taken as turnover connection edges. The energy-saving and efficient motor housing has the advantages that (1) individual positioning plate and cover board are not needed; component parts of the motor housing are reduced; and the positioning marks are directly arranged on the shell, so that the positioning accuracy of assembly is directly improved; the assembly welding procedure is removed; and the production efficiency is greatly improved; (2) the pawls are directly punched from the outer circular rings on the side wall surfaces of the shells, so that scattered scraps are not generated; and reserved middle disc areas of the side wall surfaces can be taken as fixed points of a motor shaft and can also be integrally removed for other purposes; and (3) compared with an existing product, the material consumption is reduced by 30%-40%; the power consumption for production is reduced by about 60%; and the manufacturing cost is significantly reduced.

Description

A kind of energy-conservation, efficient, motor housing that positioning precision is high

Technical field

The present invention relates to a kind of motor housing.

Background technology

What use in the MOD of refrigerator is all micromachine, as shown in Figure 1, motor housing mainly comprises location-plate 1-1, upper shell 2-1, lower house 3-1, cover plate 4-1, upper shell 2-1, lower house 3-1 has pawl 5-1, during assembling, location-plate 1-1 and upper shell 2-1 is welded and fixed, be wound with the skeleton 6-1 of coil between upper shell 2-1 and lower house 3-1, upper shell 2-1, pawl 5-1 on lower house 3-1 and the pawl 6-2 on skeleton 6-1 matches respectively, finally cover plate 4-1 is fixed on outside lower house 3-1, the motor housing assembled is connected with outside miscellaneous part by other positioning marks such as the reference column 1-2 on location-plate 1-1.

Visible, when location-plate welds with upper shell, there is one-time positioning deviation, when the outside miscellaneous part of positioning mark and motor housing is located by connecting, there is again one-time positioning deviation, this will cause deviations to accumulate, and locates all there is certain impact for the goodness of fit between pawl, motor housing and outside miscellaneous part, cause positioning precision to reduce, assembly structure is not meticulous.This unfavorable factor, in the product that this volume of MOD is little but drive disk assembly is many, transmission mechanism is many, can highlight its negative effect brought product quality on the contrary.High to the requirement of assembly crewman, make-up machinery, or require high to the accuracy of manufacture of parts, to reach the object reducing deviation as far as possible, but to this with regard to very little parts, the obvious difficulty of these methods is larger.

Pawl on upper shell, lower house as shown in Figure 2, is that starting point forms to external radiation punching by side wall surface with the center of circle, and after punching, the scattered unnecessary material that side wall surface produces needs to remove, and is waste material, there is larger waste, is unfavorable for controlling cost.

Summary of the invention

Goal of the invention: for the problems referred to above, the object of this invention is to provide a kind of motor housing saved material, improve efficiency of assembling, reduce accumulation deviations, can energy efficient, reduces product cost.

Technical scheme: a kind of energy-conservation, efficient, motor housing that positioning precision is high, be made up of upper shell, lower house, described upper shell and/or described lower house has positioning mark, inside the side wall surface of described upper shell, described lower house, there is pawl, described pawl is from the outer ring annulus punching of described side wall surface, take the inner periphery of described outer ring annulus as the turnover fillet of described pawl.

The width of described outer ring annulus is more than or equal to described pawl height.

Described side wall surface is retained as cover plate from the disc area that the inner periphery of outer ring annulus is inside.

Described side wall surface is removed from the disc area that the inner periphery of outer ring annulus is inside.

Beneficial effect: compared with prior art, advantage of the present invention is: 1, without the need to independent location-plate and cover plate, decrease the building block of motor housing, positioning mark is set directly on housing, not only reduce place's deviations, directly enhance the positioning precision of assembling, importantly eliminate erection welding operation, significantly improve production efficiency; 2, pawl is from the direct punching of outer ring annulus of case side wall, does not produce scattered waste material, and the intermediate disc region of the side wall surface of reservation can be used as the fixing point of motor shaft, also can whole removing use except separately doing him; 3, compared to existing product, decrease the material usage of 30% ~ 40% and the productive power energy consumption of about 60%, manufacturing cost significantly reduces.

Embodiment

Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.

The motor housing energy-conservation, efficient, positioning precision is high, is made up of upper shell, lower house.

As shown in accompanying drawing 3,4, upper shell and/or lower house have positioning mark 1, and positioning mark can be the forms such as reference column, location hole, limited bayonet, has pawl 3 inside the side wall surface 2 of upper shell, lower house.

Inwardly determine that one fixed width D obtains outer ring annulus 5 with the excircle 4 of side wall surface 2, inner periphery 6 to the center of outer ring annulus 5 obtains disc area 7, pawl 3 forms from outer ring annulus 5 punching, with the turnover fillet that inner periphery 6 is pawl 3, after punching, surplus material on outer ring annulus 5 still connects together, and does not have scattered particle, waste material, does not affect housing.Pawl height in the height of pawl 3 and motor housing on skeleton should match, and the width D of outer ring annulus 5 is at least equal with the height of pawl 3, and the height being a bit larger tham pawl 3 is best.

After punching, disc area 7 is retained, and remains to connect together with outer ring annulus 5, and as lower house, disc area 7 can be used as the fixing point of motor shaft, be equivalent to the effect of existing product cover plate.As upper shell, disc area 7 whole removing can be removed, all can remove pawl punching is forward and backward, disc area 7 has certain area, and material is complete, still can utilize.

Compared to existing product, The present invention reduces independent location-plate and these two parts of cover plate, save the material of quite a few, save manufacture energy consumption, decrease location-plate and this link of upper shell erection welding, eliminate place's deviations simultaneously, directly enhance the positioning precision of assembling.
