Abstract

The utility model relates to a machining fixture, particularly to a special fixture for universal joint machining. The fixture comprises a workbench, a press screw rod, a boss, V-shaped blocks, springs, a platen, stand columns, nuts and screws, wherein the platen is fixed with the workbench through the stand columns and the nuts, the press screw rod is connected onto the platen, the boss is placed in a counter bore in the center of the workbench, the two V-shaped blocks are placed in corresponding grooves in the workbench respectively through the screws, and the springs are placed in counter bores in bottoms of the grooves of the workbench. When the fixture is used for machining universal joints with different specifications, all that is required is to replace the boss and the press screw rod with proper sizes; when the fixture is not used for machining the universal joints, the V-shaped blocks cannot fall off under the action of the screws. The fixture is convenient in clamping, reliable in clamping and high in positioning accuracy.

Description

A kind of cross axle Special Fixture for Machining

Technical field

The utility model relates to a kind of clamp for machining, especially relates to a kind of cross axle Special Fixture for Machining.

Background technology

Cross axle is the critical component of the universal driving device of automobile driving system, the flatness of perpendicularity, symmetry and each axis of cross axle four axle journals requires very high, the balance of its processing precision direct influence universal driving device and service life, the Design and manufacture level of its machining accuracy and fixture is closely related.In order to ensure crudy, must make cross axle Special Fixture for Machining, existing cross axle process equipment is horizontal borer milling machine, fixture is cross keyway calibration locator.Location is complicated, and working (machining) efficiency is low, is difficult to guarantee part processing precision.

Utility model content

In order to overcome the deficiency that location complexity, working (machining) efficiency that existing Universal joint pin machining fixture exists are low, be difficult to guarantee part processing precision, the utility model provides a kind of cross Special Fixture for Machining.

The utility model for the taked technical scheme that achieves the above object is: a kind of cross axle Special Fixture for Machining, comprise workbench, clamping screw, boss, vee-block, spring, platen, column, nut, screw, platen is fixed by column and nut and workbench, clamping screw is connected on platen, boss is placed in the counterbore of workbench center, two vee-blocks are placed on respectively on workbench in corresponding with it groove by screw, and spring is placed in the counterbore of workbench bottom portion of groove.

On workbench, there is the groove matching with boss, vee-block.

The bottom portion of groove matching with vee-block at workbench is provided with the counterbore matching with spring

On vee-block, be processed with keyway.

The beneficial effects of the utility model are:

(1) adopt boss, vee-block and clamping screw can ensure positioning precision.

(2) spring between vee-block and workbench groove, can ensure that vee-block contacts with the reliable of cross axle.

(3), while processing the cross axle of different size, only need to change boss and the clamping screw of suitable dimension.

(4) do not add man-hour, due to the effect of screw, vee-block can not drop.

In figure: 1: workbench, 2: clamping screw, 3: boss, 4:V shape piece, 5: spring, 6: platen, 7: column, 8: nut, 9: screw, 10: cross axle.

Detailed description of the invention

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

If Fig. 1 is tool structure schematic diagram of the present utility model, Fig. 2 is boss of the present utility model, spring, screw rod coordinates schematic diagram with workbench, a kind of cross axle Special Fixture for Machining, comprise workbench 1, clamping screw 2, boss 3, vee-block 4, spring 5, platen 6, column 7, nut 8, screw 9, platen 6 is fixing with workbench 1 by column 7 and nut 8, clamping screw 2 is connected on platen 6, boss 3 is placed in the counterbore of workbench 1 center, two vee-blocks 4 are placed on respectively on workbench 1 in corresponding with it groove by screw 9, spring 5 is placed in the counterbore of workbench 1 bottom portion of groove.

Add man-hour, cross axle 10 tops are compressed by clamping screw 2, in the counterbore of workbench 1 center, pack into boss 3, ensure that cross axle 10 is placed in the center of workbench 1, locate with vee-block 4 at cross axle 10 axle journal places, between vee-block 4 bottoms and workbench 1 upper groove, spring 5 is installed, and ensures that vee-block 4 fully contacts with cross axle 10, and the height that ensures cross axle 10 end face directions determines by boss 3, and be not subject to the impact of vee-block 4.Vee-block 4 riding positions are parallel or perpendicular to the axis direction of milling head slide unit, with a side end face and the milling cutter place plane parallel of guaranteeing that cross axle 10 is processed.In the time need to processing the cross axle of different size, only need to change boss and the clamping screw of suitable dimension.Do not add man-hour, due to the effect of screw 9, vee-block 4 can not drop.

Below schematically the utility model and embodiment thereof are described, this description does not have restricted, is one of embodiment of the present utility model shown in accompanying drawing yet, and actual apparatus structure is not limited to this.So those of ordinary skill in the art can also do other and change in the utility model spirit, these variations of making according to the utility model spirit certainly, all should be included in the desired scope of the utility model.
