Description

Technical Field

[0001] The utility model relates to the technical field of drive axle test equipment, in particular to a fixture position adjustment mechanism for a drive axle running-in test bench. Background Art

[0002] Before the automobile drive axle is installed on the vehicle, it needs to be run-in on a special run-in bench. The purpose of the run-in is to test the meshing of the gears, the sealing of each joint surface, the interference of parts, and the performance of the differential. However, since many manufacturers now produce a variety of drive axles with different lengths, the distance between the two V-shaped seats on both sides of the test bench that support the drive axle must be adjusted according to the different drive axles. In the existing test bench, the distance between the two V-shaped seats is mostly adjusted manually by the test personnel, with low accuracy and efficiency. Utility Model Content

[0005] Preferably, the guide rails, V-shaped drag platforms, lead screw nuts and servo motors are symmetrically arranged in two sets.

[0006] Preferably, a pressure bridge buckle is installed on the top of the V-shaped drag platform, and the free end of the pressure bridge buckle can be connected to the V-shaped drag platform by bolts.

[0007] Preferably, an accordion protective cover is provided on the outer side of the guide rail, one end of the accordion protective cover is fixedly connected to the V-shaped drag platform, and the other end is fixedly mounted on the mounting base plate through a bracket.

[0008] Beneficial effect: Compared with the prior art, the beneficial effect of the utility model is that through the setting of the screw nut and the servo motor, the V-shaped drag platforms on both sides can move left and right along the guide rail under the drive of the servo motor and the screw nut, so that the distance between the V-shaped drag platforms can be quickly adapted to different types of drive axles, which is simple to operate and efficient.
