Description
Technical field
The present invention relates to frock clamp fields, especially part essence control stress peening process frock clamp.
Background technology
When metal parts are corroded in the work environment by cyclic stress, alternating load and chemical stress, the component
Fatigue life is there is, nowadays shot peening strengthening can improve the stress structure of product surface, be used by being implanted into residual compressive stress
The cyclic stress generated under the working environment of product is resisted, so as to fulfill the fatigue life of product is improved.
The gain that shot peening strengthening is brought is very considerable, and along with the progress of industry, requirement of the market to product is also got over
Come higher.Traditional shot-peening mode of this gear is exactly all to be exposed under shot-peening environment, the surface of product all by after shot-peening,
The noise for leading to gear-box is very big, and is found by engine bench test, and the failure for product of changing products is occurred from the root of groove.
Invention content
The technical problem to be solved by the present invention is to：Part essence control can not be carried out to gear in order to solve existing shot-peening operation
The deficiency of shot-peening, the present invention provides a kind of part essence control stress peening process frock clamp, by being carried out to not needing to shot-peening
Masking, to carry out the shot-peening operation of part essence control.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of part essence control stress peening process frock clamp, including protective folder is specific, filling chip shield, bottom are fixed
Seat, involute teeth, slot position one, slot position two, head cover and tooth hub, protective folder particularly be equipped with slot position one and slot position two, slot position one with
Slot position two is adjacent, the specific internal chamber wall of protective folder be equipped with the corresponding involute teeth of tooth hub external tooth, set in shield jig body
There are filling chip shield and tooth hub, a filling chip shield, specific two of protective folder are designed between adjacent two tooth hubs
Opening is respectively equipped with head cover and fixed seat at bottom.
Specifically, the protective folder is particularly set there are three slot position one and three slot positions two, and slot position one and slot position two are mutual
Parallel, the spacing between slot position one and slot position two is identical.
Specifically, the outer ring sideline of the filling chip shield is equipped with and the matched fillet of tooth hub.
Specifically, the filling chip shield is polytetrafluoroethylene (PTFE) material.
The beneficial effects of the invention are as follows：The present invention provides a kind of part essence control stress peening process frock clamps, pass through
It is covered to not needing to shot-peening, to carry out the shot-peening operation of part essence control.

Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows composition related to the present invention.
Fig. 1 is the structure diagram of the present invention, and Fig. 2 is the state diagram when protective folder of the present invention is specifically closed, and Fig. 3 is this
The specific vertical view of protective folder of invention, Fig. 4 are the specific stereograms of protective folder of the present invention, and Fig. 5 is the tooth hub of the present invention
Stereogram.
A kind of part essence control stress peening process frock clamp, including protective folder is specific 1, filling chip shield 2, bottom are solid
Reservation 3, involute teeth 4, slot position 1, slot position 26, head cover 7 and tooth hub 8, protective folder specific 1 are equipped with slot position 1 and slot position two
6, slot position 1 is adjacent with slot position 26, the internal chamber wall of protective folder specific 1 be equipped with the corresponding involute teeth 4 of 8 external tooth of tooth hub,
Filling chip shield 2 and tooth hub 8 are equipped in protective folder specific 1, a filling protection is designed between adjacent two tooth hubs 8
Washer 2, specific 1 two openings of protective folder are respectively equipped with head cover 7 and fixed seat at bottom 3.The protective folder specific 1 is equipped with
Three slot positions 1 and three slot positions 26, slot position 1 and slot position 26 are mutually parallel, the spacing between slot position 1 and slot position 26
It is identical.The outer ring sideline of the filling chip shield 2 is equipped with and 8 matched fillet of tooth hub.The filling chip shield 2 is poly-
Tetrafluoroethene material.
Protective folder specific 1 is equipped with slot position 1 of different size and slot position 26, and slot position 1 and slot position 26 are to use respectively
Carry out the groove between the adjacent flank of tooth of corresponding teeth hub 8.The center line of slot position 1 and slot position 26 is in 30 degree of angles, along the center of circle
Third indexing distribution.When needing to carry out 8 loading of tooth hub, a piece of filling chip shield 2 is first put into, then the external tooth of tooth hub 8
Involute teeth 4 on corresponding good specific 1 internal chamber wall of protective folder so that tooth hub 8 can be located in protective folder specific 1, filled out at this time
It fills chip shield 2 to fit with 8 end face of tooth hub, and the fillet for filling 2 outer ring sideline of chip shield is matched with tooth hub end face,
