Abstract

The utility model discloses a positioning die used for a gasket drilling hole, which is formed by an upper die and a lower die that are movably hinged with each other through a screw rod and a hexagonal nut which is matched with the screw rod, and the side walls at the corresponding sides of the upper die and the lower die are respectively fixed with long handles, the lower end surface of the upper die and the middle part of the upper end surface of the lower die are respectively provided with limiting grooves, and the upper end surface of the upper die is evenly provided with 6 vertical downward positioning through holes, and corresponding drain holes are arranged at the lower die under the positioning through holes. The advantages of the utility model are as follows: the gasket can be fixedly clamped between the upper die and the lower die for positioning, and the clamping and the moving of the gasket to be processed are convenient, and the deviation of the drilling location is prevented.

Description

The boring jig of a kind of pad

Affiliated technical field

The utility model relates to a kind of mining machinery parts die for processing, is specifically related to the boring jig of a kind of pad.

Background technology

The pad that existing a kind of mining machinery is used, its profile is special, on the round barrel shape main body lateral wall of pad, be provided with the annular table that is designed to one, need to bore 6 uniform holes on the annular table, cannot be placed directly into pad on the workbench of bench drill during boring, and in the boring procedure, the pad temperature raises, be not easy to directly touch, be sought after designing a kind of jig and adapt to the boring needs with hand.

Summary of the invention

The purpose of this utility model provides the boring jig of a kind of pad, the lower surface of patrix and middle part, the upper surface of counterdie are respectively equipped with limited impression, corresponding side sidewall at upper die and lower die is fixed with long handle respectively, uniform 6 positioning through hole on the upper surface of patrix, preventing the bore position deviation, is the difficult problem of pad boring with the solution.

The purpose of this utility model is achieved in that the boring jig of a kind of pad, be movably hinged by screw rod and the hex nut that matches with screw rod by upper die and lower die and form, corresponding side sidewall at upper die and lower die is fixed with long handle respectively, be convenient to clamping and move the pad that to process, described upper die and lower die all are the short cylindrical shape, the lower surface of patrix and middle part, the upper surface of counterdie are respectively equipped with limited impression, the diameter of the limited impression of patrix and the degree of depth are consistent with the round barrel shape main body first half profile of pad, uniform 6 positioning through hole vertically downward on the upper surface of patrix, with the position consistency that needs on the annular table of pad to hole, consistent with the diameter of required boring, counterdie under the positioning through hole is provided with the last hole of corresponding leakage, the diameter of the limited impression of counterdie and the degree of depth are consistent with the Lower Half profile of the round barrel shape main body of pad, during use, the pad clamping last, locate between the counterdie, the utility model is placed on the workbench of bench drill, make the limiting through hole of drill bit patrix, press down the action bars boring of bench drill.

The utility model has the advantages that, the lower surface of patrix and middle part, the upper surface of counterdie are respectively equipped with limited impression, the pad clamping can be located between upper and lower mould, corresponding side sidewall at upper die and lower die is fixed with long handle respectively, be convenient to clamping and move the pad that to process, uniform 6 positioning through hole prevent the bore position deviation on the upper surface of patrix.

Fig. 2 is a patrix vertical view of the present utility model.

Among the figure: 1, patrix; 2, counterdie; 3, screw rod; 4, hex nut; 5, positioning through hole; 6,6 ' limited impression; 7,7 ' handle; 8, leak last hole.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

The boring jig of a kind of pad as depicted in figs. 1 and 2, be movably hinged by screw rod 3 and the hex nut 4 that matches with screw rod 3 by patrix 1 and counterdie 2 and form, corresponding side sidewall at patrix 1 and counterdie 2 is fixed with long handle 7 respectively, 7 ', described patrix 1 and counterdie 2 all are the short cylindrical shape, the middle part, upper surface of the lower surface of patrix 1 and counterdie 2 is respectively equipped with limited impression 6,6 ', the diameter of the limited impression 6 of patrix 1 and the degree of depth are consistent with the round barrel shape main body first half profile of pad, uniform 6 positioning through hole 5 vertically downward on the upper surface of patrix 1, with the position consistency that needs on the annular table of pad to hole, the diameter of the limited impression 6 ' of counterdie 2 and the degree of depth are consistent with the Lower Half profile of the round barrel shape main body of pad, counterdie 2 under the described positioning through hole 5 is provided with the last hole 8 of corresponding leakage, during use, unclamp hex nut 4, can there be enough spaces to put into pad between patrix 1 and the counterdie 2, fastening hex nut 4, the pad clamping is located between patrix 1 and counterdie 2, hold handle 7,7 ', the utility model is placed on the workbench of bench drill, make the limiting through hole 5 of drill bit patrix 1, press down the action bars boring of bench drill, hold handle 7,7 ' moves the position of pad on workbench, finishes all the other boring work.

Claims

1. boring jig of pad, be movably hinged by screw rod and the hex nut that matches with screw rod by upper die and lower die and form, it is characterized in that: described upper die and lower die all are the short cylindrical shape, the lower surface of patrix and the upper surface of counterdie middle part is respectively equipped with limited impression, is fixed with long handle respectively at the corresponding side sidewall of upper die and lower die.

2. the boring jig of a kind of pad according to claim 1 is characterized in that: uniform 6 positioning through hole vertically downward on the upper surface of patrix, the counterdie under the positioning through hole is provided with the last hole of corresponding leakage.
