It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] like Figure 1-5 As shown, the present invention proposes a vehicle drive axle test fixture, which includes a fixed platform 1 and a drive axle bracket 5. The drive axle bracket 5 is symmetrically arranged at both ends of the fixed platform 1. The drive axle bracket 5 has a guide groove 6 in its inner cavity, and a locking clamp 7 is slidably provided in the inner cavity of the guide groove 6.

[0028] A drive motor 8 is installed on the outer wall surface of the drive axle bracket 5. The power output end of the drive motor 8 is connected to a drive worm 9. A worm wheel groove 10 is opened on one side of the outer wall surface of the locking clamp 7. The worm wheel groove 10 is connected to the drive worm 9.

[0029] The locking clamp 7 has a threaded hole through the middle, which is located on one side of the worm gear groove 10. A clamping screw 11 is threadedly connected to the threaded hole, and a clamping plate 12 is movably connected to the bottom of the clamping screw 11.

[0030] It should be noted that the drive axle is hoisted and supported at both ends by the drive axle bracket 5. The drive motor 8 drives the drive worm 9, which is connected to the worm wheel groove 10 on the surface of the locking hoop 7. The locking hoop 7 can rotate in the guide groove 6 under the drive of the drive worm 9. After the locking hoop 7 rotates, it forms a closed structure with the drive axle bracket 5. The limit seat 14 and the positioning plate 15 can play a limiting role for the locking hoop 7. After the locking hoop 7 rotates, the clamping screw 11 rotates to the middle of the drive axle bracket 5. The clamping screw 11 is rotated, and the clamping screw 11 pushes the clamping plate 12 down under the action of the surface thread, and the clamping plate 12 abuts against the surface of the drive axle, realizing the quick clamping and fixing of the drive axle.

[0031] In this embodiment, as Figure 4 As shown, both the locking clamp 7 and the drive axle bracket 5 have a C-shaped structure.

[0032] It should be noted that both the locking clamp 7 and the drive axle bracket 5 have a C-shaped structure, which allows the locking clamp 7 to rotate within the guide groove 6 and form a closed structure with the drive axle bracket 5.

[0033] In this embodiment, as Figure 2 As shown, the fixed platform 1 has an adjustment groove 2 on its surface. The adjustment groove 2 is symmetrically arranged on the surface of the fixed platform 1. An adjustment seat 4 is slidably provided in the inner cavity of the adjustment groove 2. The bottom of the drive bridge bracket 5 is installed on the adjustment seat 4 by bolts. An adjustment screw 3 is rotatably provided in the inner cavity of the adjustment groove 2. The adjustment screw 3 is threadedly connected to the adjustment seat 4.

[0034] It should be noted that the bottom of the drive axle bracket 5 is bolted to the adjusting seat 4. The adjusting seat 4 is slidably connected to the adjusting slide 2. By rotating the adjusting screw 3, the adjusting screw 3 pushes the adjusting seat 4 to move in the adjusting slide 2 under the action of the surface thread, so that the distance between the two sets of drive axle brackets 5 can be adjusted so that different models of drive axles can be clamped during use.

[0035] In this embodiment, as Figure 5 As shown, a universal ball joint 13 is fixed on the surface of the clamping plate 12, and the universal ball in the universal ball joint 13 is connected to the bottom of the clamping screw 11.

[0036] It should be noted that the clamping plate 12 is movably connected to the clamping screw 11 via the universal ball joint 13, and the angle of the clamping plate 12 can be adjusted during use so that the clamping plate 12 can fit tightly against the surface of the drive axle, thereby improving the stability of clamping the drive axle.

[0037] In this embodiment, as Figure 4As shown, a positioning plate 15 is fixedly provided on the outer wall of the drive axle bracket 5. The positioning plate 15 is located on one side of the drive motor 8. A limiting seat 14 is provided at one end of the outer wall of the locking clamp 7.

[0038] The working principle and usage process of this utility model are as follows: The bottom of the drive axle bracket 5 is bolted to the adjusting seat 4. The adjusting seat 4 is slidably connected to the adjusting slide 2. By rotating the adjusting screw 3, the adjusting screw 3 pushes the adjusting seat 4 to move within the adjusting slide 2 under the action of the surface thread, which can adjust the distance between the two sets of drive axle brackets 5 so as to clamp different models of drive axles during use. The drive axle is lifted and supported at both ends by the drive axle bracket 5. The drive motor 8 drives the drive worm 9. The drive worm 9 is connected to the worm wheel groove 10 on the surface of the locking clamp 7. The locking clamp 7 can move under the drive of the drive worm 9. Rotating into the groove 6, the locking clamp 7 rotates and forms a closed structure with the drive axle bracket 5. The limiting seat 14 and the positioning plate 15 cooperate to limit the locking clamp 7. After the locking clamp 7 rotates, the clamping screw 11 rotates to the middle of the drive axle bracket 5. Rotating the clamping screw 11, the clamping screw 11 pushes the clamping plate 12 down under the action of the surface thread, and makes the clamping plate 12 abut against the surface of the drive axle. The clamping plate 12 is movably connected to the clamping screw 11 through the universal ball joint 13. The angle of the clamping plate 12 can be adjusted during use so that the clamping plate 12 can fit tightly against the surface of the drive axle, thereby improving the stability of clamping the drive axle.
