Abstract
The utility model relates to a positioning structure for a drilling jig. The drilling jig is provided with a mandril matched with a through hole in a to-be-machined product, symmetrical positioning grooves are formed in the side wall of the through hole in the to-be-machined product, and the mandril of the drilling jig is provided with positioning element rests matched with the positioning grooves opposite to the positioning grooves. According to the scheme, the problems of poor product quality and relatively high production cost caused by instable mold striping angle of a product due to inconsistence of product positioning and drilling positioning in a machining process are solved.
Description
Technical field
The utility model relates to the sintered metal product field, relates in particular to a kind of location structure that is used for the boring tool of sintered metal product.
Background technology
In the powder metallurgy industry, to the product that needs boring, usually utilize the tooth of product self to cooperate and carry out location drilling with tool.Shown in Fig. 1～3, the plug 2 on the tool 1 is holed at the needs position with after through hole 4 on the processed product 3 cooperates the location.In production; Because it is machined that product lateral aperture and upper end face need; But because himself tooth of each batch product is different with the position, upper surface; And the angle of twice moulding of intrinsic localization part of product has very big deviation, so bore angle armrest sense affirmation can't accurately guarantee bore angle.At product in when location boring, itself since product orientation partly incomplete same, thereby every batch of product bore angle fluctuation is very big.When the bore angle of product fluctuates when excessive, then have following adverse consequences: 1. a lot of product bore angles can't satisfy instructions for use; 2. need to increase full inspection angle engineering; 3. every batch products scrappage is too much.Increase production cost, influenced product quality.
Therefore, how to solve thisly in process, bore angle is unstable during because of the inconsistent product depanning that causes in product orientation and boring location, thus the product quality of bringing bad with the production cost problem of higher, be the content that the utility model will be studied.
Summary of the invention
The utility model provides a kind of location structure of the tool of holing; Its objective is that solution is in process; Product depanning angle instability during because of the inconsistent product depanning that causes in product orientation and boring location angle unstable, thereby the product quality of bringing bad with the production cost problem of higher.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of location structure of the tool of holing, said boring tool be provided with processed product on the plug of through hole coupling; Offer the detent of at least one on the sidewall of the through hole on the said processed product, the corresponding said detent of the plug of said boring tool is provided with the location convex tendon that cooperates with it.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said detent is two of symmetry, and said location convex tendon is corresponding with it, also is two of symmetry.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
1, because the utility model is provided with earlier detent on processed product, and on the plug of boring tool, the location convex tendon that matches with detent is set, thereby the orientation angle when having unified that product is holed is that the orientation angle precision is enhanced.Solve the accurate problem of bore angle during powder metallurgy is produced, simultaneously stability and the product percent of pass that improves product size had significant effect.

In the above accompanying drawing: 1, boring tool; 2, plug; 3, processed product; 4, through hole; 5, detent; 6, location convex tendon.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment:
Shown in Fig. 4～7, a kind of location structure of the tool of holing, said boring tool 1 be provided with processed product 3 on the plug 2 of through hole 4 coupling; Offer the detent 5 of at least one on the sidewall of the through hole 4 on the said processed product 3, the plug 2 corresponding said detents 5 of said boring tool 1 are provided with the location convex tendon 6 that cooperates with it.Said detent 5 is two of symmetry, and said location convex tendon 6 is corresponding with it, also is two of symmetry.
Stability for the bore angle that guarantees processed product 3 every batch of depannings; Detent 5 is set on processed product 3 earlier; And the location convex tendon 6 that setting matches with detent 5 on the plug 2 of boring tool 1; Thereby the orientation angle when having unified product boring is that the orientation angle precision is enhanced.Solve the accurate problem of bore angle during powder metallurgy is produced, simultaneously stability and the product percent of pass that improves product size had significant effect.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
