[0002] Automotive parts are the various units that make up a car and the products that serve the car. During the polishing process of automotive body parts, in order to ensure the stability of the parts during polishing and avoid shaking or displacement, a fixing device is required.

[0003] A Chinese patent with authorization announcement number CN221455676U discloses a fixing fixture for processing automotive parts, including a lateral adjustment assembly. An electric push rod is located above the lateral adjustment assembly, and a protective box is fixedly connected to the extended end of each electric push rod. An angle adjustment assembly is located inside the protective box. The angle adjustment assembly includes a second drive motor fixedly connected to the bottom of the protective box cavity. A second bevel gear meshes with a first bevel gear, and a rotating shaft is fixedly connected to the opposite end of each second bevel gear. Clamping plates are fixedly connected to the two rotating shafts. Activating the second drive motor drives the first bevel gear to rotate. Because the first and second bevel gears mesh, the rotating shaft on the second bevel gear rotates, thereby adjusting the angle of the automotive parts clamped in the middle of the clamping plates.

[0004] However, the aforementioned fixing fixture still has some problems. In practical applications, the shapes of car body parts are different, and the existing technology does not make it convenient to change the fixing plate according to the shape of the part. When faced with parts of different shapes, it is impossible to stably fix the parts, which reduces the efficiency of part processing. Therefore, a part processing fixing device is proposed to address the above problems. Utility Model Content

A connecting block is installed at the other end of the limit rod. A locking block is installed on the outer side of the connecting block. A disc is installed on the top side of the support plate outside the rotating shaft. Several locking grooves matching the locking blocks are equidistantly opened inside the disc, realizing the alternating use of the fixing clamps, improving the fixing effect of parts, and adapting to the fixing operation of parts with different shapes.

[0008] Preferably, a placement plate is installed at the center of the top side of the workbench, and the top side of the placement plate is on the same horizontal line as the bottom side of the fixing plate, which facilitates the initial placement of parts on the placement plate and then the fixing operation.

[0009] Preferably, two fixed plates are symmetrically installed on the top side of the worktable. A drive motor is installed on one side of the fixed plate, and a threaded rod is installed at the output end of the drive motor. A slide rail is provided at the inner edge of the top side of the worktable, and a sliding block is slidably installed inside the slide rail. A threaded hole is provided inside the sliding block.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4 As shown, a parts processing fixing device includes a worktable 1. Two support plates 2 are installed directly above the worktable 1. A rotating shaft 3 is rotatably installed inside the top side of the support plate 2. A handle 4 is installed at the top of the rotating shaft 3. Three connecting rods 5 are equidistantly installed on the outer side of the rotating shaft 3. A fixing clamp 6 is installed at one end of each connecting rod 5. The shapes of the fixing clamps 6 are all different. A support frame 7 is installed on the outer side of the rotating shaft 3. A limit rod 8 is slidably installed through one side of the support frame 7. A limit block 9 is installed at one end of the limit rod 8. A spring 10 is fixed between the limit block 9 and the support frame 7. The spring 10 has a small elastic coefficient and is sleeved on the outer side of the limit rod 8. A connecting block 11 is installed at the other end of the limit rod 8. A locking block 12 is installed on the outer side of the connecting block 11. A disc 13 is installed on the top side of the support plate 2 outside the rotating shaft 3. A plurality of locking grooves 14 that match the locking blocks 12 are equidistantly opened inside the disc 13.

[0024] A support column 15 is installed inside the bottom side of the workbench 1. A servo motor 16 is installed at the top of the support column 15. A rotating shaft 17 is installed at the output end of the servo motor 16. A gear 18 is installed on the outside of the rotating shaft 17. Two rectangular slots 19 are symmetrically opened on the inner side of the bottom side of the workbench 1. A movable plate 20 is slidably installed inside the rectangular slots 19. A rack 21 is installed on one side of each movable plate 20. The racks 21 are symmetrically arranged around the central axis and mesh with the gears 18. Two sliding grooves 22 are symmetrically opened on the top side of the workbench 1. The top of the movable plate 20 is slidably installed inside the sliding groove 22. The support plate 2 is fixed to the top side of the movable plate 20.

[0025] A placement plate 23 is installed at the center of the top side of the workbench 1. The top side of the placement plate 23 is on the same horizontal line as the bottom side of the fixing clamp 6. A control panel 34 is installed on one side of the workbench 1. During operation, in practical applications, the shapes of car body parts are different. In the existing technology, it is not convenient to change the fixing clamp 6 according to the shape of the parts. When faced with parts of different shapes, it is impossible to stably fix the parts, reducing the efficiency of part processing. First, the shape of the part is judged. The operator pulls the limiting block 9, so that the limiting rod 8 slides inside the support frame 7. The spring 10 is stretched. As the limiting rod 8 slides, the connecting block 11 and the locking block 12 move out of the slot inside the disc 13. When the rotating shaft 3 is no longer restricted, the handle 4 is turned to rotate the rotating shaft 3, causing the connecting rod 5 and the fixing plate 6 to rotate. The appropriate fixing plate 6 is rotated to the position aligned with the part. When the appropriate fixing plate 6 is rotated to the designated position, the operator loosens the limiting block 9. Under the reaction force of the spring 10, the limiting rod 8 slides in the opposite direction, causing the connecting block 11 and the locking block 12 to be locked again in the slot 14 of the disc 13, thereby fixing the fixing plate 6 in the current position. This completes the selection and fixing of the fixing plate 6, so as to fix the part. It realizes the rotation of the fixing plate 6, improves the fixing effect of the part, and adapts to the fixing operation of parts with different shapes.

[0026] When fixing the parts, the parts are initially placed on the placement plate 23. The servo motor 16 is started, and the servo motor 16 drives the rotating shaft 17 to rotate, causing the gear 18 to rotate accordingly. Since the gear 18 meshes with the rack 21, the rotation of the gear 18 will cause the rack 21 and the movable plate 20 to move linearly inside the rectangular groove 19, thereby causing the support plate 2 to slide inside the slide groove 22. By controlling the forward and reverse rotation and the rotation angle of the servo motor 16, the distance between the two support plates 2 can be precisely adjusted, thereby increasing or decreasing the distance between the two fixed clamping plates 6, realizing the fixing of parts of different sizes and improving the stability of fixing parts of different sizes.

[0027] Please see Figure 1 , 2 As shown in Figure 5, two fixed plates 24 are symmetrically installed on the top side of the workbench 1. A drive motor 25 is installed on one side of the fixed plate 24. A threaded rod 26 is installed at the output end of the drive motor 25. A slide rail 27 is provided at the inner edge of the top side of the workbench 1. A sliding block 28 is slidably installed inside the slide rail 27. A screw hole is provided inside the sliding block 28. One end of the threaded rod 26 passes through the screw hole and is rotatably installed inside the fixed plate 24.

[0028] A fixing frame 29 is mounted on the top side of the sliding block 28, and a cylinder 30 is mounted on the top side of the fixing frame 29. A mounting bracket 31 is mounted on the working end of the cylinder 30. A grinding motor 32 is mounted on one side of the mounting bracket 31, and a grinding roller 33 is rotatably mounted between the two sides of the mounting bracket 31. One end of the grinding roller 33 is connected to the output end of the grinding motor 32. During operation, automotive parts are the various units that make up the whole car and the products that serve the car. In the grinding process of automotive body parts, in order to carry out the grinding operation on the parts comprehensively, the drive motor 25 is started, and its output end drives the threaded rod 26 to rotate, so that the sliding block 28 will move on the slide rail 2. The grinding roller 33 moves laterally along the axial direction of the threaded rod 26 to adjust its lateral position so that it can be aligned with different parts of the part. When the grinding roller 33 moves to the appropriate lateral position, the cylinder 30 is activated. The working end of the cylinder 30 extends or retracts, driving the mounting bracket 31 to move up and down, adjusting the distance between the grinding roller 33 and the part so that the grinding roller 33 can contact the surface of the part, achieving comprehensive and efficient grinding of the part. During grinding, the grinding motor 32 is activated. The output end of the grinding motor 32 drives the grinding roller 33 to rotate. The rotating grinding roller 33 performs grinding operations on the surface of the part, removing burrs, unevenness, etc., and improving the surface performance of the part.

[0029] Working principle: First, based on the shape of the part, the operator pulls the limiting block 9, causing the limiting rod 8 to slide inside the support frame 7. The spring 10 is stretched. As the limiting rod 8 slides, the connecting block 11 and the locking block 12 disengage from the slot 14 inside the disc 13. At this time, the rotating shaft 3 is no longer limited. Then, the handle 4 is turned to drive the rotating shaft 3 to rotate, causing the connecting rod 5 and the fixing plate 6 to rotate. The appropriate fixing plate 6 is rotated to the position aligned with the part. When the appropriate fixing plate 6 is rotated to the designated position, the operator loosens the limiting block 9. Under the reaction force of the spring 10, the limiting rod 8 slides in the opposite direction, causing the connecting block 11 and the locking block 12 to be locked again inside the slot 14 of the disc 13. This fixes the fixing plate 6 in the current position, completing the selection and fixing of the fixing plate 6 for fixing the part. This realizes the rotation of the fixing plate 6, improves the fixing effect of the part, and adapts to the fixing operation of parts with different shapes.

[0030] When fixing the parts, the parts are initially placed on the placement plate 23. The servo motor 16 is started, and the servo motor 16 drives the rotating shaft 17 to rotate, which causes the gear 18 to rotate accordingly. Since the gear 18 meshes with the rack 21, the rotation of the gear 18 will cause the rack 21 and the movable plate 20 to move linearly inside the rectangular groove 19, which will drive the support plate 2 to slide inside the slide groove 22. By controlling the forward and reverse rotation and the rotation angle of the servo motor 16, the distance between the two support plates 2 can be precisely adjusted, thereby increasing or decreasing the distance between the two fixed clamping plates 6, realizing the fixing of parts of different sizes and improving the stability of fixing parts of different sizes.

[0031] Start the drive motor 25, whose output end drives the threaded rod 26 to rotate, causing the sliding block 28 to move laterally along the axial direction of the threaded rod 26 within the slide rail 27. Adjust the lateral position of the grinding roller 33 so that it can be aligned with different parts of the part. When the grinding roller 33 moves to the appropriate lateral position, start the cylinder 30. The actuating end of the cylinder 30 extends or retracts, driving the mounting bracket 31 to move up and down, adjusting the distance between the grinding roller 33 and the part so that the grinding roller 33 can contact the surface of the part, achieving comprehensive and efficient grinding of the part. During grinding, start the grinding motor 32, whose output end drives the grinding roller 33 to rotate. The rotating grinding roller 33 performs grinding operations on the surface of the part, removing burrs, unevenness, etc., and improving the surface performance of the part.
