Description

A kind of device of realizing jump ring and motor shaft clamping

Technical field

The utility model relates to a kind of device of realizing jump ring and motor shaft clamping.

Background technology

Existing external rotor electric machine, in structural design, shaft room in motor shaft one end and outer rotor is interference fit, the other end of motor shaft and middle cover axle sleeve are also interference fit, do not prevent raising one's hat fixing, motor shaft and outer rotor axle sleeve, middle cover axle sleeve one are expanded with heat and contract with cold by affecting of environment temperature, and therefore the phenomenon that motor shaft comes off inevitably occurs.For above-mentioned phenomenon, application number is that the patent document of CN200920197493.7 has adopted the shaft room in motor shaft one end and outer rotor to adopt jump ring clamping, complete the program of above-mentioned jump ring clamping, need on the axle journal of motor output shaft, mill out the groove that two groove bottom are parallel to each other, this groove is referred to as jump-ring slot, jump ring is stuck in jump-ring slot, but the direction due to the flat mouthful of very difficult control flume of groove position, by craft, place opening jump ring to jump-ring slot position, the artificial Circlip tongs that adopts is large by jump ring support, accompanying drawing 3 has been shown a kind of Circlip tongs, but the whole jump ring of realizing supports large process, owing to receiving the big or small impact of artificially exerting oneself, that jump ring opening may be supportted is too large, cause jump ring deformation excessive, affect jump ring installation quality, the efficiency of installment work is simultaneously low.For the defect of the problems referred to above, the automatic crimping device of the opening jump ring that application number is 201320687346. 4, can snap fit onto opening jump ring in the jump-ring slot on motor shaft, replace manually, but we scrutinizes the technical scheme of this patent.

This patent mainly comprise for Coaxial Superimposed store jump ring material storage mechanism, compression joint mechanism and for by axial workpiece to be assembled along Nogata to fixing detent mechanism; Described compression joint mechanism comprise jump ring push pedal and for drive jump ring push pedal along continuous straight runs away from or near the crimping unit of axial workpiece to be assembled, described jump ring push pedal is provided with for holding the draw-in groove of jump ring near the plate end place of axial workpiece one side to be assembled, and the notch of this draw-in groove is towards axial workpiece to be assembled; Described detent mechanism is positioned to the jump-ring slot on axial workpiece to be assembled and corresponding section, draw-in groove position; Jump ring axis in described material storage mechanism is vertically arranged, jump ring can be along material storage mechanism landing to jump ring push pedal and between axial workpiece to be assembled gripper shoe place, between the lower end of described material storage mechanism and gripper shoe, be provided with gap, this clearance height is greater than the thickness of a jump ring and is less than the thickness of two jump rings, and jump ring push pedal pushes to the jump ring in gripper shoe in jump-ring slot.

Still the problem existing is: this device of the first, adopt jump ring push pedal and for drive jump ring push pedal along continuous straight runs away from or near the crimping unit of axial workpiece to be assembled, show that it is by Level Promoting jump ring that jump ring snaps fit onto in the jump-ring slot of motor, complete the clamping of jump ring and motor jump-ring slot, enough large (opening of jump ring is stretched and just can completes clamping until be greater than the diameter of jump-ring slot) that the opening of this process jump ring will support, accompanying drawing 1, 2 have shown two kinds of jump rings, for the jump ring of accompanying drawing 1, can apply this device and complete jump ring clamping operation, for the jump ring of accompanying drawing 2 because of its jump ring opening less, by this device, jump ring support is completed greatly to too large (jump ring opening is stretched and recycles the restorable ability of self deformation is limited) that jump ring clamping operation can cause the support of jump ring opening, cause jump ring deformation excessive, can not realize well the jump-ring slot interference fit with motor shaft.

Its two, this device adopted for Coaxial Superimposed store jump ring material storage mechanism, compression joint mechanism and for by axial workpiece to be assembled along Nogata to the fixing mechanisms such as detent mechanism, overall structure is comparatively complicated, cost is higher.

Utility model content
