Description

Technical Field

[0001] The utility model belongs to the technical field of detection fixtures, and in particular relates to a detection fixture for an automobile differential housing. Background Art

[0002] The automobile differential is the main part of the drive axle. Its function is to transmit power to the half-axles on both sides while allowing the two half-axles to rotate at different speeds, so that the wheels on both sides can travel in unequal distances in a pure rolling form as much as possible, reducing the friction between the tires and the ground. After the automobile differential is produced, the internal or end face dimensions of the differential need to be inspected.

[0003] During the existing inspection of automobile differential housing, most of them are placed on a small platform and then measured. However, these methods cannot fix the differential housing well, which not only wastes measurement time but also affects the measurement accuracy. Therefore, we propose a detection fixture for automobile differential housing. Utility Model Content

[0004] The utility model aims to provide a detection fixture for a vehicle differential housing, so as to solve the problem that the existing vehicle differential housing lacks a certain fixing mechanism during the detection period proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a detection fixture for an automobile differential housing, comprising a base, a mounting seat is provided on the top of the base, a support plate is provided on the top of the mounting seat, a limiting hole is provided on the top surface of the support plate, a cylinder is provided on the top of the base, a top plate is provided on the top of the cylinder, an output shaft is provided on the top of the top plate, a connecting block is provided on the top of the output shaft, a connecting groove is provided on the inner side of the connecting block, a cross bar is provided on the inner side of the connecting groove, a fixing block is provided on the bottom of the support plate, a connecting rod is provided on the top of the fixing block, and a limiting rod is provided on the bottom of one end of the cross bar.

[0006] Preferably, a mounting seat is fixedly connected to the middle of the top of the base, a support plate is fixedly installed on the top of the mounting seat, and limiting holes are fixedly provided on the top surface of the support plate and the surface of the mounting seat.

[0007] Preferably, a cylinder is fixedly installed on the top of the base near the edge. There are four cylinders, which are respectively installed at the four corners of the top of the base. The top of the cylinder is fixedly connected to a top plate, and an output shaft is slidably connected to the top surface of the top plate. The bottom end of the output shaft is fixedly connected to the top output end of the cylinder.

[0008] Preferably, a connecting block is fixedly connected to the top end of the output shaft, and a connecting groove is fixedly opened on the inner side of the connecting block.

[0009] Preferably, a cross bar is rotatably connected to the inner side of the connecting groove, and a fixing block is fixedly connected to one side of the bottom of the supporting plate. Four fixing blocks are provided, and the bottom of the fixing block is fixedly connected to the top of the top plate.

[0010] Preferably, the top of the fixed block is rotatably connected to a connecting rod, the top end of the connecting rod is rotatably connected to the bottom end of the cross bar, and the bottom end of one end of the cross bar is fixedly connected to a limiting rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The device can drive the output shaft to pull one end of the cross bar through the operation of the cylinder. The cross bar uses the top of the connecting rod as a support point. When the output shaft drives one end of the cross bar to move downward and rotate, the limit rod at the other end of the cross bar will tilt upward. At this time, the car differential is in a loose state. When the output shaft drives one end of the cross bar to move upward, the limit rod at the other end of the cross bar rotates downward, thereby achieving a fixed clamping effect on the car differential on the surface of the support plate, which is convenient for detection.
