Abstract

The utility model discloses a slow -witted tool is prevented in three dowelling jig holes of engine piston only, including the tool body, the left side of tool body is the inclined plane, and the right side of tool body is the plane, the inclined plane is 167 degrees with the contained angle of horizontal plane, be equipped with first location pinhole and second location pinhole on the tool body right side, be equipped with the locating pin in first location pinhole and the second location pinhole respectively, the upper surface of locating pin is higher than planar surface, be equipped with the hole of stepping down on the tool body right side, hole site in the right side of first location pinhole of stepping down. The utility model discloses simple structure, effectual solved that preceding process hole does not drill through and the quality has been improved to the bad problem that flows.

Description

A kind of engine piston body three hole drilling Anti-stopping fixture
Technical field
This utility model relates to engine piston field, refers more particularly to a kind of engine piston body three hole drilling Anti-stopping fixture.
Background technology
At present, because there being three holes on engine piston body, when causing boring hole when not drill through the most in process of production due to some problem, this operation can not effectively be detected, and then flows into subsequent processing, causes product bad.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art to provide a kind of simple in construction, practical engine piston body three hole drilling Anti-stopping fixture.
This utility model realizes in the following way:
A kind of engine piston body three hole drilling Anti-stopping fixture, it is characterized in that: include jig body 1, the left side of described jig body 1 is inclined-plane 11, the right side of jig body 1 is plane 12, described inclined-plane 11 is 167 degree with the angle of horizontal plane, is provided with the first dowel hole 13 and the second dowel hole 14 on the right side of described jig body 1;It is respectively equipped with alignment pin 2 in described first dowel hole 13 and the second dowel hole 14;The upper surface of described alignment pin 2 is higher than the surface of plane 12;Being provided with resigning hole 15 on the right side of described jig body 1, described resigning hole 15 is positioned at the right side of the first dowel hole 13.
The centrage of described first dowel hole 13 and the centrage of the second dowel hole 14 are on same vertical line.
The beneficial effects of the utility model are: simple in construction, by two alignment pins, effectively solve front operation hole and do not drill through and the bad problem that flows out, improve quality.
Accompanying drawing explanation
Fig. 1 this utility model structural front view;
Fig. 2 this utility model structure top view.
Detailed description of the invention
In conjunction with accompanying drawing in detail, this utility model detailed description of the invention is described in detail:
As shown in Figure 1 and Figure 2, a kind of engine piston body three hole drilling Anti-stopping fixture, including jig body 1, the left side of jig body 1 is inclined-plane 11, the right side of jig body 1 is plane 12, inclined-plane 11 is 167 degree with the angle of horizontal plane, is provided with the first dowel hole 13 and the second dowel hole 14 on the right side of jig body 1;It is respectively equipped with alignment pin 2 in first dowel hole 13 and the second dowel hole 14;The upper surface of alignment pin 2 is higher than the surface of plane 12;Being provided with resigning hole 15 on the right side of jig body 1, resigning hole 15 is positioned at the right side of the first dowel hole 13.
The centrage of this utility model the first dowel hole 13 and the centrage of the second dowel hole 14 are on same vertical line.
During use, engine piston body 3 is placed in jig body 1, match with alignment pin 2 in two holes on engine piston body 3, can detect whether on engine piston body 3 two holes drill through, effectively solve front operation hole not drill through and the bad problem that flows out, improve quality.
