Abstract
The invention discloses a tooth shaping work fixture which comprises a main body of a workpiece, wherein teeth are arranged on the upper end of the main body of the workpiece, a flange is arranged on the lower end of the main body of the workpiece, an elastic core fixing sleeve is sheathed outside the lower end of the main body of the workpiece and fixedly connected with the flange, and a fastening ring is sheathed outside the elastic core fixing sleeve. The tooth shaping work fixture has the advantages of high positioning accuracy, convenience and simplicity for clip installation, and high efficiency. The effect of a positioning gap is eliminated, recalibration is not needed after clip installation, and the tooth shaping quality completely reaches process requirements that Fr is less than 0.03, and Fbeta is less than 0.011. The rejection rate is greatly reduced, and the manufacturing cost is reduced.
Description
Technical field
The present invention relates to a kind of gear shaping frock clamp.
Background technology
The needs that have in the existing gearbox are used the structure of 5-linked gear shaft, and the 5-linked gear shaft is to be difficult to processing, especially insert the 2# tooth; Main cause is that this 5-linked axle is a top gear, the accuracy of gear is required height, and can not adopt on the structure to roll and shave technology; When inserting the 2# tooth, Working position is far from locating surface, by the requirement of 2# tooth; Fr＜0.03, F β＜0.011.Be difficult to the requirement that reaches such with conventional gear shaping method.If use scroll chuck, scroll chuck is contained on the workbench of gear shapping machine, clamp and roughly ground on Φ 34 cylindricals of workpiece, the 2# tooth is inserted in the face grinding location, and its shortcoming is: because workpiece is elongated, still must proofread and correct behind (1) clamping workpiece; (2) location clamps inconvenience, and efficient is low; (3) gear shaping can't meet the quality requirement, and the workpiece clamping and positioning is unstable, Fr behind the gear shaping＞0.08, F β＞0.03.
Summary of the invention
The technical problem that the present invention mainly solves provide a kind of simple in structure, easy to assembly, positioning accuracy is high, the gear shaping frock clamp that can reduce the number of rejects and seconds rate, reduces production costs.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of gear shaping frock clamp is provided, comprises the workpiece main body, said workpiece main body upper end is provided with tooth; Said workpiece main body lower end is provided with flange; The workpiece main body is arranged with the elasticity core sleeve outside the lower end, and said elasticity core sleeve is fixedly connected with flange, and said elasticity core sleeve is arranged with tight loop outward.
In preferred embodiment of the present invention, offer some open slots on the said elasticity core sleeve.
In preferred embodiment of the present invention, be fixedly connected through screw between said elasticity core sleeve and the flange.
In preferred embodiment of the present invention, be fixedly connected through screw between said elasticity core sleeve and the tight loop.
In preferred embodiment of the present invention, said elasticity core sleeve is an elastic caoutchouc.
The beneficial effect of gear shaping frock clamp of the present invention is:
(1) positioning accuracy is high, owing to be elastic construction, has eliminated the influence in gap, location;
(2) convenient mounting and clamping is simple, need not behind the clamping to proofread and correct again, and efficient is high;
(3) the gear shaping quality reaches technological requirement fully, Fr＜0.03, F β＜0.011;
(4) percent defective greatly reduces, and has reduced production cost.
Description of drawings
Fig. 1 is the perspective view of gear shaping frock clamp one preferred embodiment of the present invention;
The mark of each parts is following in the accompanying drawing: 1, workpiece main body, 2, tooth, 3, flange, 4, the elasticity core sleeve, 5, tight loop, 6, screw.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of gear shaping frock clamp; Comprise workpiece main body 1; Said workpiece main body 1 upper end is provided with tooth 2, and said workpiece main body 1 lower end is provided with flange 3, and the workpiece main body is arranged with elasticity core sleeve 4 outside 1 lower end; Said elasticity core sleeve 4 is fixedly connected with flange 3, the said elasticity core sleeve 4 outer tight loops 5 that are arranged with.
Offer some open slots on the said elasticity core sleeve 4, wherein two open slots are 120 degree, play centering, positioning action; Other two is 60 degree; Lower by 0.5 than locating surface, play clamping action, workpiece main body 1 is in clamping process like this; Do not influence its location, positioning accuracy height and workpiece main body 1 can not walked about.
Be fixedly connected good fixing effect, easy installation and removal through screw between said elasticity core sleeve 4 and the flange 3.
Be fixedly connected through screw 6 between said elasticity core sleeve 4 and the tight loop 5, through tight loop 6 elasticity core sleeve 4 be positioned on the workpiece main body 1 effectively, the location better.
Said elasticity core sleeve 4 is an elastic caoutchouc, and cost is lower, and is easy to make, and it is convenient to change.
During assembling,, elasticity core sleeve 4 is set in workpiece main body 1 lower end earlier at workpiece main body 1 lower end mounting flange 3; And elasticity core sleeve 4 is fixed on the flange 3 with screw; Sheathed tight loop 5 outside elasticity core sleeve 4 then, and fixing with screw 6, at last can be in workpiece main body upper end gear shaping 2.
This gear shaping frock clamp not only production efficiency is very high, and production cost greatly reduces, by present batch process, but 2000 yuan/month of direct saving.After this gear shaping frock clamp used, the operative employee was easy to use, if the required precision of workpiece gear shaping is not very high words also to be extended on other gear shapping machines and use, more can on axle type gear gear shaping operation, be widely used.
Compared with prior art, gear shaping frock clamp of the present invention has following advantage:
(1) positioning accuracy is high, owing to be elastic construction, has eliminated the influence in gap, location;
(2) convenient mounting and clamping is simple, need not behind the clamping to proofread and correct again, and efficient is high;
(3) the gear shaping quality reaches technological requirement fully, Fr＜0.03, F β＜0.011;
(4) percent defective greatly reduces, and has reduced production cost.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
