[0024] Reference Figure 1-Figure 4 A front and rear axle test fixture comprises a chassis 1, one side of the chassis 1 is fixed with two symmetrically distributed guide frames 2 by bolts, one side of the guide frame 2 is an inclined surface, one side of the chassis 1 is provided with a power assembly for driving the axle to move, the upper surface of the chassis 1 is fixed with two fixing frames 8 by bolts, the opposite sides of the two fixing frames 8 are provided with a clamping mechanism for fixing the axle, one side of the two fixing frames 8 is provided with a slide groove 13, and the slide groove 13 is detachably connected with a clamping frame 14 by a fixing mechanism, the axle is pushed from the inclined surface of the guide frame 2 to contact with the fixing frame 8 by the power assembly, and then the position of the axle is fixed by the fixing mechanism to prevent the axle from falling from the fixing frame 8, and then the clamping mechanism is used to clamp and fix the axle, so as to test the axle without using other tools, thereby improving the efficiency of installation and removal of the axle.

[0025] Among them, the power component includes a avoidance groove 7, which is opened on both sides of the base frame 1, and a rotating plate 9 is rotatably connected between the inner walls of the two sides of the avoidance groove 7. Two hydraulic cylinders 6 are fixed to one side of the rotating plate 9 by bolts, and the extending ends of the two hydraulic cylinders 6 are fixed with rotating blocks 17, and one end of the rotating block 17 is rotatably connected to the pulling frame 4. The two hydraulic cylinders 6 are started at the same time, and the hydraulic cylinders 6 contract to drive the two pulling frames 4 to move at the same time, so that the pulling frame 4 drives the axle to move on the inclined surface of the guide frame 2. A connecting ring 5 is welded on one side of the two pulling frames 4. When one of the hydraulic cylinders 6 is damaged, the two pulling frames 4 can move synchronously to prevent the axle from deflecting and falling during the movement, thereby improving the convenience of the device.

[0026] Among them, the clamping mechanism includes a connecting block 12, which is rotatably connected to one side of the fixing frame 8. A sliding hole penetrating the connecting block 12 is opened on the top of the connecting block 12. A sliding rod 11 is slidably connected in the sliding hole, and the sliding rod 11 is fixed to the connecting block 12 by screws. A pressure plate 10 is welded to the top of the sliding rod 11.
