Abstract

The utility model discloses a diesel injector hole fixture which comprises a fixture base 5. A base body 7 is arranged on the fixture base 5 and forms an 18-degree angle in the horizontal direction, and the surface of the base body 7 forms a 12-degree angle in the vertical direction. Two locating pins 6 are arranged on the surface of the base body 7, and 2-6 contour blocks 1 are arranged on the surface of the base body 7. A locating hole 3 is formed in the fixture base 5, and the angle of the base body is fixed. A workpiece is placed on the surface of the base body and is located through the locating pins, the locating hole is aligned before the workpiece is machined, and a workpiece machining original point can be calculated according to the distances from the locating hole to the locating pins. The diesel injector hole fixture is accurate in locating and ensures product quality.

Description

Diesel injector hole fixture
Technical field
The present invention relates to a kind of fixture, belong to the mechanical device field, specifically, particularly a kind of diesel injector hole fixture.
Background technology
In the diesel engine manufacturing, the processing of oil injector hole is cumbersome something always, because oil injector hole is positioned at the diesel engine cylinder cover incline position, during processing, angle is difficult to control, working depth can't guarantee, now along with scientific and technological development, increasing producer is used numerical control machining center to solve this problem, due to oil injector hole X, Y-direction has the angle requirement, cylinder cap needs higher orientation angle when location, and do not have a kind of both accurate positioning fixtures fast in prior art, easily occur that owing to lacking effective location the oil injector hole position is inaccurate in process, the defects such as dimension overproof, have a strong impact on product quality.
Summary of the invention
For addressing the above problem, the invention discloses a kind of diesel injector hole fixture of registration.
For achieving the above object, technical scheme of the present invention is as follows:

As a modification of the present invention, the auxiliary positioning piece is set on described clamp base.
As a modification of the present invention, described matrix surface is provided with 4 isometry blocks.
As a modification of the present invention, described clamp base both sides are provided with 2-6 arc groove.
The invention has the beneficial effects as follows:
Owing to having adopted above scheme, the fixture angle is fixed, and accurate positioning has been avoided the problem that may occur in the process, has improved product quality, has guaranteed stable quality.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The left view that Fig. 2 is Fig. 1;
Reference numerals list:
1 isometry block, 2 auxiliary positioning pieces, 3 locating holes, 4 arc grooves, 5 clamp base, 6 alignment pins, 7 matrixes.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand the following specific embodiment and only for the present invention is described, is not used in and limits the scope of the invention.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of particular elements geometric center.
Diesel injector hole fixture as depicted in figs. 1 and 2, comprise clamp base 5, matrix 7 from the horizontal by 18 ° of angles is set on described clamp base 5, matrix 7 surfaces become 12 ° of angle settings with vertical direction, matrix 7 surfaces are provided with 2 alignment pins 6, matrix 7 surfaces are provided with 2-6 piece isometry block 1, described clamp base 5 is provided with locating hole 3, the clip base angle is fixed, workpiece is placed on matrix surface, by alignment pin, locate, first being processed is found locating hole accurately, utilizes locating hole to go out the workpiece working origin to the distance transform between alignment pin.Adopt above-mentioned fixture, accurate positioning, guaranteed product quality.
As a modification of the present invention, on described clamp base 5, auxiliary positioning piece 2 is set, can find out whether workpiece locates, if there is the inaccurate situation in location to occur, the auxiliary positioning piece can play position-limiting action.
As a modification of the present invention, described matrix 7 surfaces are provided with 4 isometry blocks 1.
As a modification of the present invention, described clamp base 5 both sides are provided with 2-6 arc groove 4, facilitate the stationary fixture base.
The invention has the beneficial effects as follows:
Owing to having adopted above scheme, the fixture angle is fixed, and accurate positioning has been avoided the problem that may occur in the process, has improved product quality, has guaranteed stable quality.
