Abstract
An end cover riveted motor comprises a front cover, a rear cover, a start inserting piece and a rotor press-mounting piece. Riveting-hole flanges of the rear cover are respectively inserted into riveting holes of the front cover. The front cover is riveted to the rear cover, so that the stator inserting piece in the front cover and the rotor press-mounting piece in the rear cover are fastened. According to the end cover riveted motor, operation is simple and convenient, materials are saved, the cost is reduced, the motor assembling efficiency is improved, the coaxiality of the motor after assembly is ensured, the electromagnetic air gaps of the motor are uniform, and noise of the motor is low.
Description
Technical field
The utility model relates to machine field, particularly relates to end cover rivet button motor.
Background technology
On household electrical appliance, to use a large amount of motors, the assembling mode of conventional motors, mainly undertaken fastening by the mode of screw, screw is passed to ending cover hole, put plain washer, spring washer, nut, the overall dimension of these 4 parts is all less, when assembling motor, more difficult assembling, every motor need be provided with 4 groups of screws, plain washer, spring washer, nut, and leakiness cartridge screw, plain washer, spring washer, nut a kind of part wherein, complicated operation, inefficiency, wastes a large amount of manpowers, financial resources.On a streamline of motor assembling at present, there is 3-5 people for rigging screw, plain washer, spring washer, nut, use end cover rivet buckle instead and can save 4 procedures, utilize riveting catching groove and the riveting button hole flange on end cap, processed to carry out riveting button, save screw, plain washer, spring washer, 4 parts of nut, only carry out riveting with 1 people and fill just passable.
And traditional mode of operation, when every motor is installed 4 groups of screws, plain washer, spring washer, nut, need tightening respectively with electric wrench a group by a group, motor after tightening is because of stressed inconsistent, axiality does not reach requirement, when motor uses, noise is large, and contaminated environment greatly reduces useful life of motor.
Summary of the invention
The purpose of this utility model will provide end cover rivet button motor exactly, and it can overcome the above problem that prior art exists.The purpose of this utility model is achieved in that end cover rivet button motor, comprises protecgulum, bonnet, stator insertion, rotor press-mounting part, it is characterized in that: the bonnet riveting button hole flange on bonnet inserts in the protecgulum riveting button hole on protecgulum; By the riveting button of protecgulum and bonnet, make to be arranged on protecgulum and tighten together with stator insertion, rotor press-mounting part in bonnet.The utility model is simple to operation, has saved material, has reduced cost, has improved the efficiency of assembling motor, has guaranteed the axiality after motor assembling, and motor electromagnetic air gap is even, and motor noise is little.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail;
End cover rivet button motor, comprise protecgulum 1, bonnet 8, stator insertion 6, rotor press-mounting part 7, it is characterized in that: the bonnet riveting button hole flange 18 on bonnet 8 inserts in the protecgulum riveting button hole 15 on protecgulum 1, riveting button by protecgulum 1 with bonnet 8, makes to be arranged on protecgulum 1 and tightens together with stator insertion 6, rotor press-mounting part 7 in bonnet 8.
On described protecgulum 1, be provided with protecgulum riveting button hole 15, on bonnet 8, be provided with bonnet riveting catching groove 17; The inner side of described bonnet riveting catching groove is provided with bonnet riveting button hole flange 18.
Protecgulum riveting button hole 15 on described protecgulum 1 is corresponding with bonnet riveting button hole flange 18 positions on bonnet 8, and number equates.
Described rotor press-mounting part 7 is made up of rotating shaft 11, rotor die casting component 12 and bearing 13.
When concrete enforcement, at present traditional motor assembling line, stator insertion installing hole is enclosed within on bonnet installing hole flange, rotor press-mounting part is put into the bearing chamber of bonnet; Protecgulum is enclosed within stator insertion installing hole, and a streamline needs 3-5 people to assemble and tightens screw, plain washer, spring washer, nut.Due to motor final assembly requirement, screw specification is M3-M6 substantially, and screw length is only than the high 3-5mm of stator insertion, when assembling, and the more difficult assembling of screw.
Use the motor of end cover rivet button instead, for example: bonnet riveting button hole flange is buckled in protecgulum riveting button hole, put into end cover rivet dress mould, disposable the whole rivetings of 4 bonnet riveting button hole flange are buckled well; Do not need the connection of 4 groups of screws, plain washer, spring washer, nut, ensured the axiality of motor, reduced the noise of motor, motor gas-gap is even, and magnetic is close stable, and motor performance is good, and temperature rise is low; The efficiency of assembling that has improved motor, has reduced manufacturing cost.
The utility model also can be processed protecgulum riveting button hole flange on protecgulum, processes bonnet riveting button hole on bonnet, and protecgulum riveting button hole flange is corresponding with bonnet riveting button hole position, and number equates.
Reach equally installation effect, also in protection range of the present utility model.
