The outer wall of the upper end of the bracket 2 penetrates and is slidably connected to a carrier seat 17. The carrier seat 17 provides support for the rotation of the worm 13 and provides support for the rotation of the worm gear 14. The front outer wall of the carrier seat 17 is elastically connected to an insert block 10 through a first spring 9. The setting of the insert block 10 is to fix the carrier seat 17. When the insert block 10 leaves the inner wall of the bracket 2, the carrier seat 17 can be moved to adjust the height of the clamping plate 4. The rear outer wall of the insert block 10 is slidably connected to the inner wall of the front end of the carrier seat 17, and the rear outer wall of the insert block 10 penetrates and is slidably connected to the inner wall of the front end of the bracket 2. One end of the first spring 9 is fixedly connected to the front outer wall of the carrier seat 17, and the other end of the first spring 9 is fixedly connected to the rear outer wall of the insert block 10. The inner wall of the front end of the carrier seat 17 is rotatably connected to a worm 13. The rotation of the worm 13 drives the rotation of the worm gear 14. The left outer wall of the worm 13 meshes with the worm gear 14. The worm gear 14 rotates through the worm 13, thereby driving the connecting frame 3 to rotate. A connecting frame 3 is fixedly connected to the inner wall of the worm gear 14. The connecting frame 3 is used to connect the worm gear 14 and the clamping plate 4. The connecting frame 3 provides support for the rotation of the worm gear 14. The front side outer wall of the bottom end of the connecting frame 3 is rotatably connected to the inner wall of the upper end of the carrier seat 17, and the rear side outer wall of the bottom end of the connecting frame 3 is rotatably connected to the inner wall of the upper end of the carrier seat 17. A clamping plate 4 is fixedly connected to the rear outer wall of the connecting frame 3. The clamping plates 4 are symmetrically arranged. The two clamping plates 4 are used to fix the automotive parts. The outer wall of the bracket 2 is slidably connected to the base 1. The base 1 provides support for the detection device. An adjusting component is fixedly connected to the inner wall of the upper end of the base 1. A fixing frame 6 is fixedly connected to the outer wall of the upper end of the base 1. The fixing frame 6 is arranged in an L shape. The fixing frame 6 provides support for a cylinder 7. The front side outer wall of the bottom end of the fixing frame 6 is fixedly connected to a cylinder 7. The cylinder 7 is used to drive the hardness detector 8 to move. The bottom outer wall of the cylinder 7 is fixedly connected to a hardness detector 8. The hardness detector 8 is used to detect the hardness of the parts.

[0032] Referring to Figure 1 and Figure 4, the cleaning component includes a rotating block 15. The rotating block 15 is arranged to drive the cleaning brush 5 to rotate. The cleaning brush 5 can be rotated by the rotating block 15. The outer wall of the rear end of the rotating block 15 is rotatably connected to the inner wall of the front end of the fixing frame 6. The outer wall of the left end of the fixing frame 6 is elastically connected to the cleaning brush 5 through a second spring 16. Pull the cleaning brush 5 to the left to stretch the second spring 16. When the cleaning brush 5 is not in use, the second spring 16 will pull the cleaning brush 5 back. The cleaning brush 5 is used to remove the surface cleaning on the side of the part tape. The outer wall of the cleaning brush 5 penetrates and is slidably connected to the inner wall of the left end of the rotating block 15. One end of the second spring 16 is fixedly connected to the outer wall of the left end of the rotating block 15, and the other end of the second spring 16 is fixedly connected to the outer wall on the right side of the cleaning brush 5.

The threaded rod 11 rotates as the double-shaft motor 12 operates, driving the bracket 2 to move. The inner wall of the rear end of the threaded rod 11 is fixedly connected to the output shaft of the double-shaft motor 12.

[0034] Working principle: Rotate the worm 13 to drive the worm wheel 14 to rotate. The rotation of the worm wheel 14 drives the clamping plate 4 to rotate through the connecting frame 3, and the angle of the clamping plate 4 is adjusted according to the angle of the part clamping surface. After the angle adjustment is completed, move the insert block 10 forward so that the insert block 10 leaves the inner wall of the front end of the bracket 2, and then the carrier seat 17 can be moved to adjust the height of the clamping plate 4. After the adjustment is completed, start the double-shaft motor 12 to drive the bracket 2 to move through the threaded rod 11. Clamp the automotive parts with the clamping plates 4 on both sides, and then pull the cleaning brush 5 to clean the surface to be measured of the parts. Subsequently, the hardness detector 8 can be driven by the cylinder 7 to move down to detect the hardness of the parts.
