Abstract

The utility model discloses a motor case with a process clamp position, relating to a motor case structure. A circular shell is a hollow cylinder; and the excircle of the hollow cylinder is extended with a wiring box in a connecting manner, the circumference of the hollow cylinder is uniformly distributed with longitudinal thin rib pieces, and the two end surfaces of the hollow cylinder are respectively and uniformly distributed with four bosses. The motor case is characterized in that outer steps are also turned at the outer sides of the outer end surfaces of the four bosses at one end surface of the hollow cylinder, the height of each outer step is 5mm-8mm, the radial width of each outer step surface is 3mm-8mm, the axial surface of the outer step is an outer arc surface, and the four outer arc surfaces are in the same axis line. The motor case has the advantages that firstly, spigots of the four bosses are tuned, then hydraulic clamps are used for clamping the spigots of the four bosses so as to turn the upper spigots, the lower spigots, the upper ends and the lower ends, one-time clamping is achieved, all machined surfaces are in the same axis line, and the end surfaces are parallel so as to guarantee geometric accuracy.

Description

A kind of motor case with technology folder position

Technical field:

The utility model relates to motor casing structure, particularly a kind of motor case with technology folder position.

Background technology:

The structural member of motor stator core outsourcing partly is called for short casing, and casing structure is described then with this Figure of description shape and is: a from top to bottom and hollow cylinder that certain-length is arranged, and hollow cylinder has certain thickness; This outside has been covered with the random geometry of the thin muscle sheet of heat sinking function according to certain rule.Uniform respectively four boss in cylinder cylindrical two ends and end covers at two sides have locking effect.The circle two ends need be processed into the internal diameter of seam up and down of coaxial inner conductor respectively and end cap that parallel each other seam face end face is cylindrical plays location effect with one heart in the hollow cylinder.Processing of two seams middle part and the concentric interior circle cylindrical section concentric that press-fits iron core assurance iron core of the seam at two ends with seam.Motor gas-gap after the assembling evenly can not cause the electromagnet pull magnetic noise of decentraction like this, guarantees that simultaneously motor shaft does not produce circular runout.

Conventional traditional processing process of casing be in looking for earlier with motor case blank coarse positioning after, black skin and locking end cap lug clamping work pieces processing casing one end face, seam, iron core shelves outside casing, turn around then recruitment assembling close seam that motor case processed and compress after car other end, another seam, seam plane again, this processes exist blank look in again clamping time long-acting rate slow, because of the mode that clamps causes the clamping work pieces distortion that comes loose after the processing.Turn around to adopt frock to cooperate processing to have two ends seam, iron core shelves axial line deviation, two seam planes are not parallel.Exist motor shaft extension circle to beat after the casing assembling of this processes and do not satisfy standard-required, generally in 0.05mm～0.08mm scope (standard is generally in 0.03mm).Can not guarantee simultaneously the stability of noise of motor, the decentraction motor rotation also exceeds standard because of the inhomogeneous meeting generation of air gap electromagnet pull sound causes noise of motor to exceed standard and vibrates.Its process equipment is common economy numerically controlled lathe or the engine lathe and the frock that turns around.

Electromechanics trade does not have the good machine shaft circle that solves after assembling to beat and the noise of motor problem for a long time.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned defective, and a kind of motor case with technology folder position is provided.

Scheme of the present utility model is: the motor round casing is a hollow cylinder, hollow cylinder cylindrical disjunctor extends a terminal box, some vertical muscle sheets, each uniform four boss of both ends of the surface of approaching of ring Zhou Junbu, it is characterized in that: return the car and be shaped on outer step in the outside, four boss outer faces of an end face of hollow cylinder, outer shoulder height is 5mm～8mm, outer step surface radial width is 3mm～8mm, outer step axial vane surface is an exterior arc surface, four exterior arc surface coaxial inner conductors.

Advantage of the present utility model is: four boss seams of driving system earlier, reach clamping No. one time with seam end face, last seam, iron core shelves, following seam, following seam end face on hydraulically operated fixture and four boss seam car systems of special tooling gravity direction clamping then, all machine work face coaxial inner conductors, end face is parallel, guarantees the space geometry precision of motor case.

Embodiment:

Structural electromotor round casing of the present utility model is a hollow cylinder 1, hollow cylinder 1 cylindrical disjunctor extends a terminal box, some vertical muscle sheets 2, each uniform four boss 3 of both ends of the surface of approaching of ring Zhou Junbu, it is characterized in that: return the car and be shaped on outer step 4 in the outside, four boss 3 outer faces of 1 one end faces of hollow cylinder, outer step 4 highly is 5mm～8mm, outer step 4 face diameters are 3mm～8mm to width, outer step 4 axial vane surfaces are 5, four exterior arc surface 5 coaxial inner conductors of exterior arc surface.

During the outer step 4 of car system, be with reference to axial line car system,, but do not influence the axiality and the depth of parallelism of machined surface self in the subsequent handling even have deviation with reference to axial line and the theoretical axial line of motor round casing with motor round casing axial line.

Four outer steps 4 of motor round casing are placed on four hydraulically operated fixture heads that correspondence position is fixed on the vertical type numerically controlled machine rotary table by deadweight down during clamping, then the hydraulically operated fixture head tightens up to axial line, clamp four exterior arc surfaces, 5 location of outer step 4, last seam end face, seam, iron core shelves internal diameter, following seam, following seam end face that the startup lathe is processed casing respectively according to technological process process at one time the taking-up workpiece.
