[0032] The following combines the attached drawings in the embodiments of the present utility model Figures 1-4 , and clearly and completely describes the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Please refer to Figures 1-2, An anti-deviation positioning tooling for plate roller welding, including a base 1. In the middle of the upper outer surface of the base 1, a U-shaped mounting plate 2 is fixedly connected. Electric telescopic rods 1 3 are fixedly connected to both the upper and lower outer surfaces of the U-shaped mounting plate 2. The other end outer surface of the electric telescopic rod 1 3 is fixedly connected to a moving plate 4. The electric telescopic rod 1 3 penetrates through the inner wall of the U-shaped mounting plate 2. A clamp 5 is arranged on the outer surface of the moving plate 4. Through the two groups of electric telescopic rods 1 3, the two groups of moving plates 4 can be driven to move relatively, so that the clamp 5 can position and clamp the plate roller, facilitating welding. A telescopic damper 10 is fixedly connected to one side outer surface of the moving plate 4. A shock-absorbing spring 11 is sleeved on the outer wall of the telescopic damper 10. The upper outer surface of the telescopic damper 10 is fixedly connected to the clamp 5. The moving plate 4 is elastically connected to the clamp 5 through the telescopic damper 10 and the shock-absorbing spring 11. By setting the telescopic damper 10 and the shock-absorbing spring 11, the vibration generated by the rotation of the plate roller can be dampened, improving the stability of the plate roller and the welding effect.

[0034] Refer to Figures 1-2 , An electric telescopic rod 2 6 is fixedly connected to one side of the upper outer surface of the base 1. The upper outer surface of the electric telescopic rod 2 6 is fixedly connected to a fixing plate 7. One side outer surface of the fixing plate 7 is movably connected with a plug clamping mechanism 8 through a bearing. By the electric telescopic rod 2 6, the fixing plate 7 can be driven to rise and fall, so that the plug clamping mechanism 8 rises and falls, making the plug align with the plate roller.

[0035] Refer to Figures 1-3 , A clamping and rotating assembly 9 is fixedly connected to the other side of the upper outer surface of the base 1. The clamping and rotating assembly 9 includes a mounting plate 12, a constant-speed motor 13, a rotating connecting rod 14, a driving gear 15, a driven gear 16, a driving motor 17, an adjusting screw 18, a connecting disc 19, a connecting support rod 20, a through groove 21, a moving ring 22, a movable connecting rod 23, a connecting plate 24, a clamping block 25 and an anti-slip pad 26. Through the clamping and rotating assembly 9, it is convenient to clamp and rotate one end of the plate roller, facilitating the automatic rotation of the plate roller during welding and improving the welding efficiency. The mounting plate 12 is fixedly connected to one side of the upper outer surface of the base 1. A constant-speed motor 13 is fixedly connected to one side outer surface of the mounting plate 12. The constant-speed motor 13 can adjust the rotation speed to make the plate roller rotate at a constant speed. One end outer surface of the constant-speed motor 13 is movably connected with a rotating connecting rod 14. The rotating connecting rod 14 penetrates through the other side outer surface of the mounting plate 12. The other end of the rotating connecting rod 14 is fixedly connected to a driving gear 15. The driving gear 15 meshes with the driven gear 16. The driven gear 16 is movably connected to one side outer surface of the mounting plate 12. By starting the constant-speed motor 13, the rotating connecting rod 14 and the driving gear 15 are driven to rotate. Since the driving gear 15 meshes with the driven gear 16, the driven gear 16 can be driven to rotate simultaneously while the driving gear 15 rotates.

[0036] Refer toFigure 3 and Figure 4 , a driving motor 17 is fixedly connected to the middle of the outer surface of one end of the driven gear 16. The outer surface of the other end of the driving motor 17 is movably connected to an adjusting screw rod 18. The adjusting screw rod 18 can be rotated by the driving motor 17. The outer surface of the other end of the adjusting screw rod 18 is movably connected to a connecting disc 19. A connecting support rod 20 is fixedly installed between the connecting disc 19 and the driven gear 16. The connecting disc 19 can be fixed to one end of the driven gear 16 through the connecting support rod 20. A through groove 21 is formed in the outer surface of one end of the connecting disc 19, and the through groove 21 penetrates through the outer surface of the other end of the connecting disc 19. A moving ring 22 is threadedly connected to the outer wall of the adjusting screw rod 18. The outer wall of the moving ring 22 is movably connected to a movable connecting rod 23. The outer surface of the other end of the movable connecting rod 23 is movably connected to a connecting plate 24. A clamping block 25 is fixedly connected to the outer surface of one side of the connecting plate 24. The connecting plate 24 is slidably connected to the inner wall of the through groove 21. The rotation of the adjusting screw rod 18 can make the moving ring 22 move on the outer wall of the adjusting screw rod 18. When the moving ring 22 moves, it drives the movable connecting rod 23 to change the angle, so that the connecting plate 24 moves on the inner wall of the connecting disc 19. At this time, the clamping block 25 moves to clamp the plate roller. An anti-slip pad 26 is fixedly connected to the outer surface of one side of the clamping block 25. The anti-slip pad 26 makes the clamping of the plate roller more stable and can play an anti-slip role. The movable connecting rod 23, the connecting plate 24, the clamping block 25 and the anti-slip pad 26 are all in four groups. Through the four groups of movable connecting rods 23, connecting plates 24, clamping blocks 25 and anti-slip pads 26, one end of the plate roller can be clamped, and the clamping is more stable and can rotate better.

[0037] The implementation principle of the present utility model is as follows: When a deviation-preventing positioning tooling for plate roller welding is in use, first, the plate roller is positioned and fixed. The plate roller is placed between the jigs 5, and two groups of electric telescopic rods 1 are started to make the two groups of moving plates 4 move relatively until the jigs 5 clamp and position the plate roller. At this time, the plug is clamped and fixed through the plug clamping mechanism 8. The electric telescopic rod 2 is started to lift and lower the plug clamping mechanism 8 to align the plug with the central axis of the plate roller. After alignment, the staff can carry out welding. During the welding process, the plate roller needs to be rotated. First, the other end of the plate roller is clamped. The adjusting screw 18 is rotated by starting the driving motor 17. The rotation of the adjusting screw 18 enables the moving ring 22 to move on the outer wall of the adjusting screw 18. When the moving ring 22 moves, it drives the movable connecting rod 23 to change the angle, so that the connecting plate 24 moves on the inner wall of the connecting disc 19. At this time, the clamping block 25 moves to clamp the outer wall of the plate roller. A non-slip pad 26 is fixedly connected to the outer surface of one side of the clamping block 25. The non-slip pad 26 makes the clamping of the plate roller more stable and can play a role in preventing slipping. After clamping the plate roller, the uniform-speed motor 13 is started to drive the rotating connecting rod 14 to rotate at a uniform speed, so that the driving gear 15 rotates. Since the driving gear 15 meshes with the driven gear 16, when the driving gear 15 rotates, the driven gear 16 rotates, and the driven gear 16 drives the whole connecting disc 19 to rotate, so as to automatically rotate the plate roller, without the need for the staff to manually rotate it, which is more convenient and improves the welding efficiency.

Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
