Description

Fixtures for processing the inner hole and center height of the drive axle housing

technical field

The utility model relates to a fixture for processing a drive axle casing of a forklift, in particular to a fixture for processing the inner hole of the mouth surface and the center height of the drive axle casing.

Background technique

The inner hole of the mouth surface and the center height of the forklift drive axle housing are the two most important dimensions in the entire axle housing. The dimensional accuracy of the inner hole of the mouth surface directly affects the assembly accuracy of the gearbox, and the dimensional accuracy of the center height directly affects the half shaft. Assembly precision. In the prior art, when processing the forklift drive axle housing, it is difficult to control the inner hole size and center height of the above-mentioned axle housing, and it is easy to produce defective products during processing, which not only wastes manpower and material resources, but also produces The finished product is also prone to large dimensional deviations in the forklift drive axle in the subsequent installation process, so it is necessary to improve.

Contents of the invention

The purpose of the utility model is to provide a clamp for processing the inner hole of the mouth surface and the center height of the drive axle housing in order to overcome the disadvantages of the background technology.

In order to achieve the above object, the technical solution of the utility model is: a fixture for processing the inner hole of the mouth surface of the drive axle housing and the center height, which is characterized in that it includes a base, two support mechanisms arranged symmetrically at intervals, and the support The mechanism includes a support block installed on the base, a hinge screw installed on the front end of the support block and on the base, a hinge pull rod on the rear end of the support block and installed on the base, a hinge pressure plate above the support block, and a support block The upper end is equipped with a V-shaped block, and the upper end of the V-shaped block is provided with a first V-shaped groove for placing the axle casing half shaft sleeve. One end of the hinge pressure plate is hinged to the upper end of the hinge pull rod, and the other end of the hinge pressure plate is placed on the hinge screw. Both the lower end of the hinge pull rod and the lower end of the hinge screw are hinged to the base through the hinge seat.

In the above technical solution, a blanking through hole is provided at the center of the base.

In the above technical solution, an open slot is provided at the lower end of the base, and the open slot communicates with the blanking through hole and is located at the lower end of the blanking through hole.

In the above technical solution, the support block is provided with a knife relief groove at the bottom end of the first V-shaped groove.

During actual work, the staff need to place the utility model on the workbench of the vertical lathe first, then place the half-axis bushings at both ends of the axle housing on the first V-shaped groove, and then press the axle housing tightly with the hinge pressing plate The ends are pressed tightly so that the mouth of the axle housing faces upwards and is parallel to the working table, and then the drive axle housing can be processed for the inner hole of the mouth and the center height.

The blanking through hole can reduce the weight of the utility model, which not only facilitates handling, but also reduces the cost. The open slot can reduce the contact area between the bottom of the base and the workbench, and can largely avoid the problem of uneven installation caused by small debris on the workbench. Allowing the knife groove can make the staff more convenient to process the V-shaped block to produce the first V-shaped groove.

The utility model can more conveniently process the inner hole and center height of the drive axle, and make the dimensional accuracy of the inner hole of the mouth surface and the dimensional accuracy of the center height meet the requirements of actual work. At the same time, the utility model reduces the time used for processing the drive axle housing, reduces the processing cost, reduces the generation of defective products, and improves the quality of the product to a large extent.
