Description

Angle and height adjustable clamping device

technical field

The invention belongs to automobile bench test equipment, more specifically, a fixture device for adjusting and positioning the axle assembly in the inspection test of the automobile axle assembly.

Background technique

The axle assembly is an important part of the automobile system. It converts the rotation of the rotating shaft driven by the engine into the rotation of the half shaft and the wheels. Decelerate and increase torque, and make the wheels on both sides form a differential speed. The axle assembly is an important part of the vehicle load, and its fatigue strength largely determines the load-carrying capacity of the vehicle and the safety and stability of driving under various road conditions. It is one of the important contents of automobile testing to carry out relevant tests on the bridge assembly to test its transmission performance and bearing capacity.

In order to align the input shaft of the rear axle with the output shaft of the gearbox, the axle manufacturers process an inclined mounting surface on the rear axle. When testing the rear axle on the bench, since the driving equipment is often fixed, it is required to adjust the installation and positioning of the rear axle so that the input shaft of the rear axle can align with the output shaft of the driving equipment . At present, the commonly used method is to process a gasket with a certain inclination angle, and place the gasket on the bottom of the bridge to be tested, so as to adjust the height and angle of the bridge to be tested. Obviously, this method is cumbersome, and it is necessary for each Bridges of different sizes and specifications need to be equipped with different gaskets, which is time-consuming and labor-intensive, and adds a lot of trouble to design, processing, adjustment and installation.

On the shaft, a hinged form in which the hinge head bolt can rotate relative to the pin shaft is formed.

On the adjustment plate, located at one end of the adjustment plate, a raised positioning block is fixedly set; with the positioning block as a support, a movable block that can move left and right on the adjustment plate is set.

A bolt connection is used between the positioning block and the movable block. The bolt connection is fixedly provided with a long bolt on one side of the movable block. The long bolt penetrates the positioning block and is positioned and locked by a positioning nut. The position of the long bolt in the positioning block.

The invention realizes the adjustment of the angle and height of the adjustment plate with a simple mechanical structure. Compared with the prior art, the beneficial effects of the present invention are reflected in:

1. As a fixture device for bridge assemblies, the present invention can position and clamp various bridge assemblies with different external dimensions and different eccentric angles.

2. The matching structure between the hinge bolt and the adjusting plate provided by the present invention can conveniently adjust the inclination angle and vertical height of the workpiece, and has a simple structure and reliable clamping.

3. In the present invention, the raised positioning stopper on the adjustment plate can ensure reliable positioning of the workpiece, and the setting of the movable stopper can realize further precise adjustment of the position of the workpiece within a small range.

4. The present invention can not only be applied to the positioning and clamping of the axle assembly, but also can be more widely used in the clamping of other workpieces that require both horizontal positioning and adjustment of inclination angle and height.
