Abstract

The utility model relates to a locating punch for making holes. The locating punch comprises a punch head, a punch body and a punch handle, and is characterized in that the punch body has a cylindrical structure, the outer diameter of the punch body is less than the aperture of each prepared hole by 0.1-0.3mm, the top of the punch body is connected with the punch handle through a thread, the punch head is a cone which is arranged at the center of the bottom of the punch body and protrudes outwards, the cone top of the punch head is lower than the plane of the bottom of the punch body by 2-8mm. The locating punch is simple in structure, low in cost, convenient to use and accurate to locate. By adopting the locating punch, not only can the production demand be met, but also the cost can be greatly lowered.

Description

Location punching for preparation hole
Technical field
The utility model relates to the location punching, specifically location punching for a kind of preparation hole.
Background technology
In the manufacture of steel structure field, a large amount of workpiece are connected by securing members such as bolts, need to process various circular holes on workpiece as through hole, counterbore, screw etc., and before the processing of hole, the Yao Duikong center positions.Unified drilling after the workpiece that needs more than two to coordinate is superimposed, the drilling precision is the highest, when the scheme by being unified drilling after superimposed is difficult to carry out, just can only distinguish drilling, i.e. first drilling on a workpiece, then, treating on the workpiece of drilling to rule location, then carry out drilling.Drilling can adopt numerical control device to position by programming respectively, and precision is high but cost is also high; Artificial line location is convenient, but has the measure error and the line error for the treatment of the drilling workpiece of drilling, often exceeds the allowable error scope.Therefore, designing a kind of preparation hole simple in structure, with low cost, easy to use, registration rushes very necessary with location.
Summary of the invention
The purpose of this utility model just is to provide a kind of preparation hole simple in structure, with low cost, easy to use, registration and rushes with location.
For achieving the above object, the utility model adopts following technical scheme: location punching for a kind of preparation hole, comprise drift, rush body and die shank, it is characterized in that punching is as cylindrical-shaped structure, the external diameter that rushes body matches well the little 0.1~0.3mm of aperture, the top that rushes body is connected with die shank by screw thread, and drift is to be arranged at the outside outstanding cone that rushes body bottom centre, and the vertex of a cone of drift is lower than rushing body base plane 2~8mm.
Further, the described top that rushes body is provided with screw, and the bottom of described die shank is provided with screw rod, rushes body and die shank and is connected and is integral by screw and screw rod.
The utility model is simple in structure, with low cost, easy to use, registration.Adopt the utility model, can meet need of production, significantly reduced again cost.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model is used view.
In figure: the 1-drift; 2-rushes body; 2.1-screw; The 3-die shank; 3.1-screw rod.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model:
Location punching for preparation hole shown in figure, comprise drift 1, rush body 2 and die shank 3, rush body 2 for cylindrical-shaped structure, the external diameter that rushes body 2 matches well the little 0.1~0.3mm of aperture, the top that rushes body 2 is connected with die shank 3 by screw thread, drift 1 is for to be arranged at the outside outstanding cone that rushes body 2 bottom centre, and the vertex of a cone of drift 1 is lower than rushing body 2 base plane 2~8mm.
Preferred embodiment is: in such scheme, the described top that rushes body 2 is provided with screw 2.1, and the bottom of described die shank 3 is provided with screw rod 3.1, rushes body 2 and die shank 3 and is connected and is integral by screw 2.1 and screw rod 3.1.
The content be not described in detail in this specification, belong to the known prior art of those skilled in the art.
