[0008] 1. This utility model forms a clamping device by setting up a support column, groove, cylinder, hydraulic push rod, connecting plate, sleeve, slide rod, box, worktable and pressure plate. The start cylinder lowers the connecting plate through the hydraulic push rod, which in turn lowers the box and pressure plate to clamp and fix the welding parts placed on the top of the worktable, preventing the welding parts from shaking up and down, improving the stability of the welding process, facilitating welding and improving the welding effect.

[0009] 2. This utility model forms a fixing device by setting up a housing, bearing 1, rotating shaft, transmission rod, rotating wheel, gear 1, housing, bearing 2, threaded rod, gear 2, slider 1, telescopic rod, connecting rod, support plate, slide groove, slider 2, support block, and push plate. By rotating the rotating wheel, the two push plates move towards the middle position to fix the two sides of the welded part, preventing the welded part from swaying left and right during the welding process and improving the stability of the welding process. At the same time, the fixing device and the clamping device can be used together or independently, which is flexible in operation and can meet the needs of different occasions.

[0013] 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 protection scope of the present utility model.

[0014] Please see Figure 1-2 An aluminum spot welding fixture includes a base 1, a movable box 9 is provided above the base 1, a pressure plate 26 is installed at the bottom of the box 9, and a worktable 20 is provided below the pressure plate 26.

[0015] A support column 2 is installed on the top of the base 1, and the support column 2 has a through slot 3.

[0016] A cylinder 4 is installed on the top of the base 1. The cylinder 4 is located behind the support column 2. A vertically upward hydraulic push rod 5 is installed on the top of the cylinder 4. A connecting plate 6 is installed at the output end of the hydraulic push rod 5. The connecting plate 6 extends forward and passes through the slot 3. The slot 3 restricts the movement range of the connecting plate 6. The front end of the connecting plate 6 is connected to the rear side of the housing 9. Activating the cylinder 4 will cause the output end of the hydraulic push rod 5 to move up and down, and drive the housing 9 to move up and down through the connecting plate 6, and finally move the upper and lower pressure plates 26.

[0017] A sleeve 7 is installed on the top of the base 1. The sleeve 7 is located behind the cylinder 4. A sliding rod 8 is slidably connected inside the sleeve 7. The sliding rod 8 can slide up and down inside the sleeve 7. The front side of the sliding rod 8 is connected to the rear side of the connecting plate 6. When the connecting plate 6 moves up and down, the sliding rod 8 will also move up and down inside the sleeve 7 to support the connecting plate 6 and enhance the stability of the connecting plate 6 and the housing 9.

[0018] Inside the housing 9, a rotating shaft 11 is installed via a bearing 10. A gear 12 is installed at the bottom of the rotating shaft 11. Both sides of the housing 9 have downward-opening shells 13. When the housing 9 moves up and down, the shells 13 will move together. A rotating wheel 28 is installed on the top of the housing 9. The rotating wheel 28 and the rotating shaft 11 are connected by several transmission rods 27. Rotating the rotating wheel 28 will drive the rotating shaft 11 and the gear 12 to rotate through the transmission rods 27.

[0019] A threaded rod 15 is installed inside the housing 13 via a bearing 14. The end of the threaded rod 15 away from the bearing 14 extends toward the housing 9 and passes through the housing wall of the housing 9. A gear 16 is installed at the end of the threaded rod 15 away from the bearing 14. The gear 16 is located inside the housing 9 and is meshed with the gear 12. When the gear 12 rotates, it will drive the gear 16 to rotate together through meshing, and cause the threaded rod 15 to rotate.

[0020] A slider 17 is threadedly connected to the threaded rod 15. A vertically downward telescopic rod 18 is installed at the bottom of the slider 17. A connecting rod 19 is installed at the telescopic end of the telescopic rod 18. There are two connecting rods 19. A push plate 25 is installed at the opposite end of the two connecting rods 19. When the threaded rod 15 rotates, the slider 17 will move on the threaded rod 15 and drive the push plate 25 to move through the telescopic rod 18 and the connecting rod 19 to fix the welded part.

[0021] Support plates 21 are installed on both the left and right sides of the workbench 20. A slide groove 22 is opened on the top of the support plate 21. A slider 23 is slidably connected in the slide groove 22. When the connecting rod 19 moves left and right, the slider 23 will move synchronously in the slide groove 22. A support block 24 is installed on the top of the slider 23. The top of the support block 24 is connected to the bottom of the connecting rod 19 to support the connecting rod 19. When the housing 13 moves up and down, the telescopic rod 19 will extend and retract accordingly, so that the connecting rod 19 and the push plate 25 remain stationary.

[0022] In use, the operator can place the workpiece to be welded on the top of the workbench 20, and then start the cylinder 4 to lower the connecting plate 6 through the hydraulic push rod 5, which in turn lowers the pressure plate 26. The workpiece is fixed by the cooperation of the pressure plate 26 and the workbench 20. If necessary, the push plate 25 can be moved toward the workpiece by rotating the wheel 28 to further fix the workpiece.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
