Abstract
The utility model relates to a fixture, in particular to a special fixture for repairing and grinding of an overrun clutch star body, and belongs to the field of bearing machining. The special fixture for repairing and grinding of the overrun clutch star body comprises a manually-operated backup cap, a self-made pad, a shaft, a support body, a pad and a nut, wherein the shaft is assembled on the support body, a through hole is formed in the support body, the shaft is assembled on the support body through the through hole in the support body and is fixed to a jackscrew through the pad and the nut, the overrun clutch star body is arranged on the shaft and is fixed through the pad and the manually-operated backup cap, a shaft shoulder is arranged between the overrun clutch star body and the shaft and is used for positioning, and gaps exist between the shaft shoulder and the support body and between the shaft shoulder and the overrun clutch star body. The special fixture for repairing and grinding of the overrun clutch star body has the advantages that the problems that due to the fact that a large number of star bodies are used in an automatic pin roller cold header and an automatic cutting and feeding mechanism of a press machine, spar parts of the star bodies are scrapped are solved, the situation that the star bodies are scrapped after being used once is changed, the star bodies can be used repeatedly, the amount of investment of the high-cost star bodies with the spare parts complicated in structure is greatly reduced, production cost is reduced, and working efficiency is improved.
Description
Technical field
The utility model is provided with a kind of fixture, specifically relates to a kind of freewheel clutch celestial body reconditioning special fixture, and it belongs to bearing machining field.
Background technology
Before freewheel clutch celestial body reconditioning special fixture is used, due to plane that cannot five tooth lobes of the worn out celestial body of reconditioning, celestial body has all been scrapped substantially, and the most multiplex file finds the flat too large problem that also can't resolve simply.A large amount of celestial bodies that use in Z31-13, Z31-25 roller automatic cold header and 100T forcing press blank automatic feed mechanism freewheel clutch, long-term production causes some celestial body spare parts to scrap, and celestial body cost of manufacture is high in addition, wastes quite serious, must innovate, to reduce costs.
Summary of the invention
In view of the problem that prior art exists, the purpose of this utility model is to provide a kind of surface grinding machine magnechuck that depends on that the bottom surface of support is adsorbed in after workbench and the freewheel clutch celestial body reconditioning special fixture of work.
To achieve these goals, the technical scheme that the utility model adopts is freewheel clutch celestial body reconditioning special fixture, and it comprises: manually standby cap, self-control pad, axle, stake body, pad and nut; Axle is assemblied on support, described stake body is provided with through hole, axle is assemblied on support by the through hole on support, and fix by pad and nut and jackscrew, freewheel clutch celestial body is assemblied on axle, and fix with pad and manually standby cap, between freewheel clutch celestial body and axle, there is a shaft shoulder location, the shaft shoulder has gap between stake body and freewheel clutch celestial body.
Described direction of principal axis is identical with movable workbench direction.
Described freewheel clutch celestial body and axle are matched in clearance.
The thickness of described pad is greater than common pad.
The described manual rotation for cap 1 is fastening is inserted manually and is realized for cap side opening by spanner lever.
Use the course of work of the utility model processing freewheel clutch star to be: the magnetic suction disc work top of surface grinding machine is cleaned out, then whole clamp body is put thereon, clamp body bottom surface is fully contacted with the work top of grinding machine, described clamp body is axially identical with movable workbench direction, open magnetic suction disc power supply, make clamp body firmly be adsorbed in work top.Axle is assemblied on support, utilize the acting in conjunction of right side pad, nut and jackscrew be fixed and prevent rotation, then loading onto celestial body makes by flat surface grinding centering, get self-control pad and manually standby cap ready location clamping again, each free degree that has limited celestial body obtains the duty of grinding, movable workbench direction should be axially consistent with special fixture, finally does grinding work.After plane of grinding, then unclamp manually standby cap rotation celestial body and do next flat surface grinding work, operate according to this, complete the reconditioning task of 5 equal portions planes of celestial body.
Of the present utility modelly be a little: solved a large amount of celestial bodies that use in roller automatic cold header and forcing press blank automatic feed mechanism freewheel clutch, the celestial body spare part causing is scrapped, changed the disposable situation of scrapping of celestial body, can repeated multiple timesly use, this spare part complex structure, investment that cost is high are significantly reduced, saved production cost, operating efficiency is provided.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, manually standby cap 2, self-control pad 3, celestial body 4, axle 5, stake body 6, pad 7, nut.
The specific embodiment
In order further to understand this freewheel clutch celestial body reconditioning special fixture, below in conjunction with accompanying drawing, be described as follows.
It comprises: manually standby cap 1, self-control pad 2, axle 4, stake body 5, pad 6 and nut 7, part 3 is work piece celestial body.Axle 4 is assemblied on stake body 5, and stake body is provided with through hole, and axle is assemblied on support by the through hole on support, axle 4 and stake body 5 by padding 6, nut 7 and jackscrew fix.Freewheel clutch celestial body 3 is assemblied on axle 4, the assembly relation of celestial body and axle adopts more loose matched in clearance, and fixing with self-control pad 2 and manually standby cap 1, use self-control pad and the difference of common pad to be that self-control pad can strengthen thickening, with enlarge active surface, promote frictional force and gain in strength, fastening must the need in a manually standby cap side opening of auxiliary spanner lever insertion of rotation of manually standby cap 1.Between freewheel clutch celestial body and axle, there is a shaft shoulder location, and with this, increase frictional resistance and prevent that celestial body from rotating on axle, it is mainly to make empty cutter that the shaft shoulder leaves gap between stake body and celestial body, to wheel grinding, provide process conditions, when five tooth lobes of part 3 celestial body are ground, the moving direction of emery wheel is the axial of part 4 axles, there will not be celestial body rotation or move axially phenomenon, the corresponding increase that reduces to depend on wedge rollers size that the plane of five tooth lobes of celestial body is ground rear size supplements, and can not affect result of use.
Use the whole course of work of this fixture processing freewheel clutch celestial body to be: before five tooth lobe flat surface grindings of freewheel clutch celestial body, should first the magnetic suction disc work top of M131 surface grinding machine be cleaned out, then whole clamp body is put thereon, clamp body bottom surface A is fully contacted with the work top of grinding machine, attention should make described clamp body axially identical with movable workbench direction, open magnetic suction disc power supply, make clamp body firmly be adsorbed in work top.Then load onto freewheel clutch celestial body fastening as stated above, on the left of being just drilled with locating hole and the shaft shoulder while making due to celestial body right side, alignment pin is housed, so can make soon to want roll flute lobe plane positioning, five tooth lobe plane rotation grinding action patterns are identical, the flat surface grinding amount that it is worth mentioning that five tooth lobes wants consistent, is convenient to like this unification of supporting roller size.Open power supply and the cooling fluid of grinding machine and cut down door, grinding program starts, the like.
