Abstract
The invention relates to a fixture, in particular to a special fixture for star body repairing and grinding of an overrunning clutch, belonging to the field of bearing machining. The special fixture comprises a manual backup cap, a self-made pad, a shaft, a bracket body, a pad and a nut. The shaft is assembled on a bracket. A through hole is formed in the bracket body. The shaft is assembled on the bracket through the through hole in the bracket and is fixed with a jackscrew through the pad and the nut. The star body of the overrunning clutch is assembled on the shaft and is fixed with the manual backup cap by using the pad. A shaft shoulder is positioned between the star body of the overrunning clutch and the shaft. The shaft shoulder is provided with a gap between the bracket body and the star body of the overrunning clutch. The special fixture for star body repairing and grinding of the overrunning clutch has the advantages that the problem that star bodies which are largely used in overrunning clutches of cut material automatic feeding mechanisms of roller automatic cold headers and presses are discarded is solved, the situation that the star bodies are discarded after single use is changed, the star bodies can be repetitively used, the investment in spare parts which are complex in structure and high in cost is greatly reduced, the production cost is reduced and the working efficiency is improved.
Description
Technical field
The present invention is provided with a kind of fixture, specifically relates to a kind of freewheel clutch celestial body reconditioning special fixture, and it belongs to the bearing machining field.
Background technology
Before freewheel clutch celestial body reconditioning special fixture is used, due to plane that can't five tooth lobes of the worn out celestial body of reconditioning, celestial body has all been scrapped basically, 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 the 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 objective of the invention is to provide a kind of and depend on that the surface grinding machine magnechuck is adsorbed in the workbench back by the bottom surface of support and the freewheel clutch celestial body reconditioning special fixture of working.
To achieve these goals, the technical solution adopted in the present invention 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, the freewheel clutch celestial body is assemblied on axle, and fix with pad and manually standby cap, a shaft shoulder location is arranged between freewheel clutch celestial body and axle, the shaft shoulder has gap between stake body and freewheel clutch celestial body.
Described direction of principal axis is identical with the 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 rotation of described manually standby cap 1 is fastening is inserted manually and is realized for the cap side opening by the spanner lever.
The course of work of using the present invention to process the freewheel clutch star is: the magnetic suction disc work top of surface grinding machine is cleaned out, then whole clamp body is put thereon, the clamp body bottom surface is fully contacted with the work top of grinding machine, described clamp body is axially identical with the movable workbench direction, open the 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 the flat surface grinding centering, to make again pad by oneself and manually for cap, get location ready and clamp, each free degree that has limited celestial body obtains the duty of grinding, the movable workbench direction should be axially consistent with special fixture, finally does grinding work.Behind plane of grinding, then unclamp manually standby cap rotation celestial body and do next flat surface grinding work, operation, complete the reconditioning task on 5 equal portions planes of celestial body according to this.
Of the present inventionly 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 caused 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
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 the 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 the self-control pad can strengthen thickening, promote frictional force and gain in strength with enlarge active surface, the rotation of manually standby cap 1 is fastening must need an auxiliary spanner lever to insert in manually standby cap side opening.One shaft shoulder location is arranged between freewheel clutch celestial body and axle, and increase frictional resistance with this 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, provide process conditions to wheel grinding, when five tooth lobes of part 3 celestial body are ground, the moving direction of emery wheel is the axial of part 4 axles, not there will be the celestial body rotation or move axially phenomenon, the corresponding increase that reduces to depend on the 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 the movable workbench direction, open the 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 just being drilled with locating hole and the shaft shoulder while making due to the 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.
