Abstract
The utility model provides an expansion positioning pin, which includes a main body part, an inserting part arranged at the lower end of the main body part, and an inserted pin matched with the main body part, wherein a tapered hole is arranged in the main body part; the inserted pin is matched with the tapered hole; and the inserted pin includes a head part, and a tapered part extending from the head part and matched with the tapered hole. In the utility model, as the tapered hole is arranged in the main body part and the inserted pin is matched with the tapered hole, the main body part can be expanded and enlarged through inserting the inserted pin, so that the main body part can be tightly matched and firmly connected with a work piece, and looseness is avoided; and the expansion positioning pin has the advantages of stable operation, high finished product ratio and low cost.
Description
Technical field
The utility model relates to a kind of expansion locating stud.
Background technique
At present, known common locating stud, all less than fluting, be used for joining work pieces after, in the process that workpiece uses, can occur rocking, thereby cause locating stud loosening, make job insecurity, the machining accuracy step-down, yield rate is low, thereby has increased cost.
Summary of the invention
The technical problem that the utility model will solve provides a kind of working stability, and yield rate is high, the expansion locating stud that cost is low.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: comprise main part, and be arranged on the insertion part of main part lower end, and the latch that cooperates with main part; Be provided with cone shape hole in the said main part, said latch cooperates with cone shape hole.
Further, said latch comprises head, and is extended the tapered portion that matches with cone shape hole by head.
The expansion locating stud of the utility model, owing to be provided with cone shape hole in the said main part, said latch cooperates with cone shape hole; Through inserting latch, can main part be expanded becomes big, thereby cooperates closely with workpiece; Be connected firmly the situation that can not occur becoming flexible, its working stability; Yield rate is high, and cost is low.
Description of drawings
Fig. 1 is the schematic representation that the utility model expansion locating stud cooperates with workpiece.
Embodiment
In the present embodiment, with reference to Fig. 1, said expansion locating stud comprises main part 1, and is arranged on the insertion part 2 of main part 1 lower end, and the latch 3 that cooperates with main part 1; Be provided with cone shape hole 10 in the said main part 1, said latch 3 cooperates with cone shape hole 10.Can main part 1 be expanded becomes big, thereby cooperates closely with workpiece, be connected firmly, and the situation that can not occur becoming flexible, its working stability, yield rate is high, and cost is low.
Wherein, said latch 3 comprises head 30, and is extended the tapered portion 31 that matches with cone shape hole 10 by head 30.
The expansion locating stud of the utility model, owing to be provided with cone shape hole in the said main part, said latch cooperates with cone shape hole; Through inserting latch, can main part be expanded becomes big, thereby cooperates closely with workpiece; Be connected firmly the situation that can not occur becoming flexible, its working stability; Yield rate is high, and cost is low.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
