Abstract
The utility model discloses a trimming and positioning clamp for the fracture channel surface of an outer ring fractured thin-wall bearing, and belongs to the technical field of bearing machining. The trimming and positioning clamp comprises a compressing screw, an annular positioning clamp and a positioning screw, and is characterized in that the outer-diameter surface of the annular positioning clamp is provided with a V-shaped groove; the positioning screw is arranged below the V-shaped groove; one side of the annular positioning clamp is provided with a crescent compressing sheet; the diameter of a central hole of the annular positioning clamp is the same as the outer diameter of a machined outer ring. The trimming and positioning clamp for the fracture channel surface of the outer ring fractured thin-wall bearing is simple in structure, is convenient to operate, can be used for rapidly and effectively trimming the outer ring fracture channel surfaces of a small batch of outer ring fractured thin-wall bearings, and has a remarkable effect and high working efficiency. The requirements of the bearing on vibration and noise are not influenced by the channel surface, thereby prolonging the service life of the bearing.
Description
Technical field
The utility model belongs to technical field of bearing processing, relates in particular to the finishing positioning fixture of a kind of outer ring breaking type thin-wall bearing fracture channel surface.
Background technology
At present, the outer ring fracture of outer ring breaking type ball bearing is after finished product lasso is examined eventually, on the axial direction of external diameter, slots, and then adopts special frock to make its fracture.Specifically bearing outer ring is inserted in to an axle with tapering, pressure ring is pressed on cycle surface, pressure ring is applied to power, in the time that the large end of axle is passed through in outer ring, cause that at bottom land stress is concentrated due to the shape of groove, lasso just can be along the fracture of fluting direction, the tapering of axle will draw through test of many times, should make outer ring fracture, can not cause again the radial plastic deformation of lasso, due to the impact of various factors, can there is the defects such as out-of-flatness in the post-rift fracture in outer ring, affect the normal use of bearing, so must repair fracture channel surface.
Summary of the invention
The utility model provides the finishing positioning fixture of a kind of outer ring breaking type thin-wall bearing fracture channel surface, can repair fast and effectively the outer ring fracture channel surface of the outer ring breaking type thin-walled ball bearing of small lot, make channel surface not affect the requirement of bearing to vibration and noise, thus the service life of improving bearing.
In order to achieve the above object, the technical scheme that the utility model adopts is: the finishing positioning fixture of a kind of outer ring breaking type thin-wall bearing fracture channel surface, comprise housing screw 1, circular orientation fixture 2, dog screw 3, the outer diametric plane of circular orientation fixture 2 is provided with V-shaped groove, below V-shaped groove, be provided with dog screw 3, a side of circular orientation fixture 2 is provided with crescent clamping piece.
Concrete, described circular orientation fixture 2 center-hole diameters are identical with the external diameter of processed outer ring.
The beneficial effects of the utility model are: the finishing positioning fixture of a kind of outer ring breaking type thin-wall bearing fracture channel surface, it is simple in structure, easy to operate, can repair fast and effectively the outer ring fracture channel surface of the outer ring breaking type thin-walled ball bearing of small lot, successful, operating efficiency is high, makes channel surface not affect the requirement of bearing to vibration and noise, thus the service life of improving bearing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
1. housing screws in figure, 2. circular orientation fixture, 3. dog screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, the finishing positioning fixture of a kind of outer ring breaking type thin-wall bearing fracture channel surface, comprise housing screw 1, circular orientation fixture 2, dog screw 3, the outer diametric plane of circular orientation fixture 2 is provided with V-shaped groove, below V-shaped groove, be provided with dog screw 3, a side of circular orientation fixture 2 is provided with crescent clamping piece.
Concrete, described circular orientation fixture 2 center-hole diameters are identical with the external diameter of processed outer ring.
When work, circular orientation fixture 2 lies on workbench, processed outer ring is put into the endoporus of circular orientation fixture 2, makes dog screw 3 enter breaking groove, and the datum end face of outer ring is concordant with the datum end face of circular orientation fixture 2, then compresses with housing screw 1; Circular orientation fixture 2 entirety are placed on the tire of end face location, adjust lower support piece, make the center of circular orientation fixture 2 and lathe (emery wheel) center contour, V-shaped groove coordinates with rear bearing block; Then the upper magnetic of energising, fixes whole circular orientation fixture 2 and processed outer ring, adjusts the axial location between emery wheel and outer ring raceway, the finishing of carrying out outer ring fracture channel surface is exited emery wheel after having repaired, demagnetization, take down circular orientation fixture, unclamp housing screw, take out the outer ring being trimmed.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
