The number of the clamping mechanisms is eight and they are centrally symmetrically distributed on the top of the test bench 2.

[0022] By adopting the above technical scheme, it is possible to use eight clamping mechanisms and clamps 44 in eight directions to clamp automobile parts of different shapes, and the rotating screw 47 can control the mounting block 42 and drive the clamp 44 to move, so as to clamp automobile parts of different sizes. The limit assembly 46 and the positioning block 45 are used to release the fixation of the clamp 44, so that it is convenient for the staff to regularly replace the clamp 44 that is severely worn, thereby making the clamp 44 more versatile.

[0023] In this embodiment, the clamping mechanism includes a rectangular groove 41, which is opened on the top of the test bench 2. A mounting block 42 is slidably installed inside the rectangular groove 41. A limit strip is fixedly installed on the rear side wall of the inner cavity of the rectangular groove 41. A limit groove is opened on the back of the mounting block 42. The inner wall of the limit groove is slidably connected to the outer surface of the limit strip, so as to limit the mounting block 42 to move left and right only on the outer surface of the limit strip. A mounting box 43 is fixedly installed on the top of the mounting block 42. A clamp 44 for clamping different automotive parts is sleeved on the outer surface of the mounting box 43, which is convenient for clamping automotive parts. Two positioning blocks 45 for fixing the position of the clamp 44 are arranged inside the mounting box 43. Mounting grooves are opened on the left and right sides of the mounting box 43. The two positioning blocks 45 are respectively slidably installed inside the two mounting grooves, so as to limit the positioning block 45 to move only on the mounting groove. A limit assembly 46 for limiting the position of the two positioning blocks 45 is arranged inside the mounting box 43.

[0024] Among them, the limit assembly 46 includes a threaded rod and a limit block, the limit block is threadedly installed on the outer surface of the threaded rod, the left and right sides of the limit block are slidingly connected to the left and right side walls of the inner cavity of the installation box 43 respectively, the threaded rod is rotatably installed between the inner top wall and the inner bottom wall of the installation box 43, one end of the threaded rod passes through and extends to the outside of the installation box 43, and one end of the threaded rod is fixedly connected with a ring handle, which is convenient for rotating the threaded rod to control the limit block to move up, thereby releasing the position restriction on the two positioning blocks 45, and then facilitating the disassembly and replacement of the severely worn clamp 44.

[0025] By adopting the above technical solution, it is possible to control the mounting block 42 to drive the mounting box 43 to move toward the direction of the automobile parts. According to the shape of the automobile parts, an appropriate number of mounting boxes 43 are controlled to drive the clamp 44 to move toward the automobile parts until the automobile parts are clamped on the top of the test bench 2. In addition, it is convenient to rotate the threaded rod in the limit assembly 46 to control the limit block to move upward, thereby releasing the position restriction of the two positioning blocks 45, thereby making it convenient for the staff to disassemble and replace the clamp 44 that is severely worn.

[0026] In this embodiment, a screw rod 47 with one end passing through and extending to the outside of the test bench 2 is rotatably installed inside the rectangular groove 41, and a mounting block 42 is threadedly installed on the outer surface of the screw rod 47. A support assembly 48 for supporting the rotation of the screw rod 47 is provided on the outer peripheral wall of the test bench 2. The support assembly 48 includes a circular groove and a bearing.
