[0038] The first adjustment component 2 includes two uprights 21, both of which are fixed to the base 1. Slider 22 is slidably mounted on each of the two uprights 21. A fixing block 23 is fixed between the two sliders 22. The first motor 7 is fixed to the fixing block 23. A threaded sleeve 24 is fixed to the bottom of the fixing block 23. A first threaded rod 25 is engaged with the internal thread of the threaded sleeve 24. The bottom end of the first threaded rod 25 is fixed to the output end of the second motor 8.

[0039] Hydraulic rods 27 are fixedly connected to the sides of both sliders 22, and a fixing plate 28 is fixedly connected between the working ends of the two hydraulic rods 27. The spline shaft 29 is rotatably mounted on the side of the fixing plate 28, and a baffle 26 is fixedly connected to the top of both uprights 21.

[0040] The rotating assembly 3 includes a positioning bushing 31, which is fixedly connected to the fixing block 23. The splined hollow shaft 32 is rotatably installed in the positioning bushing 31. A gear ring 33 is fixedly connected to the splined hollow shaft 32. A gear 34 meshes with the gear ring 33, and the gear 34 is fixed to the output end of the first motor 7.

[0041] The second adjustment component 4 includes a hollow beam 41, which is fixed to the end of the spline shaft 29. Extension beams 42 are slidably arranged in the openings at both ends of the hollow beam 41. Multiple positioning holes 43 are evenly distributed on the side of the hollow beam 41. Threaded grooves 44 are opened on the side of the two extension beams 42. A first bolt 45 is threaded into the threaded groove 44, and the first bolt 45 passes through the corresponding positioning hole 43.

[0042] Limiting rods 46 are fixed to the sides of the ends of the two extension beams 42 located outside the hollow beam 41. Mounting blocks 47 are slidably provided on the two limiting rods 46, and the clamping assembly 5 is installed on the side of the mounting block 47.

[0043] Both mounting blocks 47 have threaded holes through their sides, and a second threaded rod 48 is inserted through each of the two threaded holes. The ends of the two second threaded rods 48 are rotatably mounted on the sides of the two extension beams 42, respectively. The ends of the two limiting rods 46 are fixedly connected to a second baffle 49, and the ends of the two second threaded rods 48 are rotatably mounted on the sides of the two second baffles 49, respectively. The ends of the two second threaded rods 48 are fixedly connected to a rotating disk 410.

[0044] The clamping assembly 5 includes a C-shaped member 51, which is fixedly connected to the side of the mounting block 47. A guide rail 52 is provided on the inner wall of the C-shaped member 51, and a sliding plate 53 is slidably arranged on the guide rail 52. A hole is opened through the C-shaped member 51, and a nut 54 is fixedly connected to the opening of the hole. A second bolt 55 is engaged with the internal thread of the nut 54, and the end of the second bolt 55 is rotatably mounted on the sliding plate 53.

[0045] During operation, the existing fixing device is too large, making it inconvenient for workers to operate when processing the middle of parts using machining equipment. This requires workers to stand on the base, increasing the risk of falls and injuries. In this solution, by controlling the rotation of motor 8, the first threaded rod 25 rotates within the threaded sleeve 24, causing it to retract. As the threaded sleeve 24 descends, it slides on the two uprights 21 via the fixing block 23, thereby raising and lowering the component mounted on the first adjusting assembly 2 and lowering the height of the second adjusting assembly 4. The automotive parts are then fixed to the two clamping assemblies 5. Finally, motor 8 is operated again. The fixing block 23 is raised to lift the parts fixed on the two clamping assemblies 5 to a height that is convenient for workers to process. After the automotive parts are lifted, they can be processed by the processing equipment. The first motor 7 is controlled to run. When the first motor 7 runs, it drives the gear ring 33 through the gear 34. When the gear ring 33 rotates, it drives the spline hollow shaft 32 to rotate in the positioning bushing 31. When the spline hollow shaft 32 rotates, it drives the spline shaft 29 to rotate. When the spline shaft 29 rotates, it drives the hollow beam 41 to rotate. When the hollow beam 41 rotates, it drives the two extension beams 42 to rotate as well, so that the clamping assemblies 5 fixed at the ends of the two extension beams 42 are flipped. In this way, the parts fixed on the two clamping assemblies 5 are flipped so that the lower part of the parts can be processed.

[0046] When automotive parts are too large to be easily machined in their middle, the height of the fixed block 23 is adjusted and the hydraulic rod 27 is retracted. When the hydraulic rod 27 retracts, it drives the spline shaft 29 to slide in the spline hollow shaft 32. The spline shaft 29 extends to the side opposite to the first adjustment component 2 and the counterweight 6, thereby adjusting the distance between the second adjustment component 4 and the fixed block 23. In conjunction with rotating the rotating disk 410, the rotating disk 410 drives the second threaded rod 48 to rotate. When the second threaded rod 48 rotates, it drives the mounting block 47 to slide on the limit rod 46, thereby adjusting the distance between the mounting block 47 and the extension beam 42. This allows workers to machine around the parts and allows workers to directly contact the workpiece surface without having to climb to heights.

[0047] By removing the No. 1 bolt 45 from the threaded groove 44 and its corresponding through positioning hole 43, the extension beam 42 can slide telescopically within the hollow beam 41, thereby further adjusting the distance between the fixed parts on the two clamping assemblies 5, further improving the operator's working space for processing, and by retracting the two extension beams 42 into the hollow beam 41, the distance between the two clamping assemblies 5 is reduced, so that the fixed parts on the two clamping assemblies 5 can be spliced ​​together, improving processing convenience, and making it applicable to the processing of parts of different sizes;

[0048] When automotive parts are fixed by clamping assembly 5, the parts are placed inside C-shaped part 51, and then the second bolt 55 is rotated. When the second bolt 55 rotates, it will drive the sliding plate 53 to slide on the guide rail 52. When the sliding plate 53 slides down, the parts can be clamped and fixed by the sliding plate 53 and the side wall of C-shaped part 51.

[0049] This device effectively secures automotive parts and, compared to traditional automotive parts fixing devices, makes it easier to process the parts and effectively prevents accidents caused by workers having to climb to heights.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
