Description

Automobile generating machine support machining fixture

Technical field

The utility model relates to jig during a kind of Cutter Body Processing with Machining Center machine components, the jig particularly during a kind of Cutter Body Processing with Machining Center automobile generating machine support.

Background technology

Automobile engine has cylindrical housings, and automobile engine uses automobile current generator support installing on the vehicle frame of automobile.Automobile generating machine support has the arc plate with the circular cylindrical shell mates of automobile engine, two sides of arc plate there is the abduction edge on string face, abduction edge there are four installing holes vertical with string face and multiple connecting hole, the aperture of installing hole and connecting hole is respectively in the inside and outside of arc plate, and there is the circular technology groove that two axis are vertical with string face the inside of arc plate.

When making automobile generating machine support, first make automobile current generator support pressure strand material, then use the endoporus of machining center processing mounting holes and connecting hole on automobile current generator support pressure strand material, on arc plate inside and outside, installing hole processes the installed surface parallel with string face or joint face respectively with the aperture of connecting hole.

During work in-process heart processing parts blank, need part blank to be stuck on the workbench of machining center.Because automobile current generator support pressure strand material out-of-shape, wall unevenness are even, very difficult on workbench automobile current generator support pressure strand material being stuck in machining center, in prior art, do not have automobile current generator support pressure strand material to be stuck in the automobile generating machine support machining fixture on the workbench of machining center.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, proposes a kind of automobile generating machine support machining fixture that automobile current generator support pressure strand material can be stuck on the workbench of machining center.

The utility model realizes with the following method.

Automobile generating machine support machining fixture has base plate, and there is the first jig in the left side of substrate, and there is the second jig on the right side of base plate,

First jig and the second jig have the air clamper of the front and rear at substrate respectively, the cylinder that the air clamper of front and rear has axis vertical with base plate, forward and backward cylinder is other has cylinder saddle respectively, is hinged with double leval jib between the piston rod of cylinder and its bearing

Two elastic positioning pins having axis vertical with base plate between the forward and backward air clamper of the first jig and three alignment pins,

The alignment pin that four axis are vertical with base plate is had between the forward and backward air clamper of the second jig.

The utility model can be made into: two elastic positioning pins of the first jig match with two circular technology grooves inside automobile current generator support pressure strand material; Three alignment pin height of the first jig are equal, wherein have two alignment pins to match with two installing holes of automobile current generator support pressure strand material; Four alignment pins of the second jig match with four installing holes of automobile current generator support pressure strand material; Double leval jib hinged between the piston rod of cylinder and its bearing has lever and fork, lever is connected on the piston rod of cylinder, when the piston rod of cylinder stretches out, lever rises, fork declines, when automobile current generator support pressure strand material is placed on the alignment pin of jig, fork declines and can be pressed in tightly on automobile current generator support pressure strand material.

During use, first base plate of the present utility model is stuck on the workbench of machining center, then automobile current generator support pressure strand material is first placed on the first jig, in two the circular technology grooves allowing two of the first jig elastic positioning pins be inserted in inside automobile current generator support pressure strand material, two installing holes of the inside of automobile current generator support pressure strand material and abduction edge is allowed to be placed on three alignment pins of the first jig, then automobile current generator support pressure strand material is lain on the first jig and can not be rotated, allow before the first jig again, exhaust hood piston rod stretches out, then the fork of double leval jib declines and is pressed on automobile current generator support pressure strand material tightly, automobile current generator support pressure casting bloom stable, be stuck on the first jig securely, with the installing hole of Cutter Body Processing with Machining Center automobile current generator support pressure strand material and the endoporus of connecting hole and the aperture installed surface of installing hole and connecting hole or joint face, realize the processing inside automobile current generator support pressure strand material.

After completing the processing inside to automobile current generator support pressure strand material, allow before the first jig, exhaust hood piston rod is retracted, then the fork of double leval jib rises, remove the thrust to automobile current generator support pressure strand material, automobile current generator support pressure strand material is taken off from the first jig, turn and rear four installing holes are placed on four alignment pins of the second jig, allow before the second jig again, exhaust hood piston rod stretches out, then the fork of double leval jib declines and is pressed on automobile current generator support pressure strand material tightly, automobile current generator support pressure casting bloom stable, be stuck on the second jig securely, with the installing hole of Cutter Body Processing with Machining Center automobile current generator support pressure strand material and the endoporus of connecting hole and the aperture installed surface of installing hole and connecting hole or joint face, realize the processing outside automobile current generator support pressure strand material.

The utility model can be stuck on the workbench of machining center out-of-shape, wall unevenness even automobile current generator support pressure strand material, conveniently uses machining center machining.

Below in conjunction with accompanying drawing, the utility model is further described.
