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.

[0022] Example 1:

[0023] Please refer to the following: Figures 1-4 This utility model provides a technical solution: a flipping mechanism for welding automotive parts, comprising a base plate 1 and two rotating plates 2. Two movable plates 3 are movably inserted into the outer surfaces of each of the two rotating plates 2. Support plates 5 are fixedly connected to the opposing outer surfaces of the two rotating plates 2. Extrusion plates 4 are fixedly connected to the outer surfaces of the two movable plates 3. Several teeth 7 are fixedly connected to the outer surface of one of the movable plates 3. A support rod 6 is fixedly connected to the outer surface of the rotating plate 2. A rotating shaft 8 rotatably passes through the outer surface of the support rod 6. A transmission gear 9 is fixedly sleeved on the outer surface of the rotating shaft 8. The outer surfaces of the wheel 9 and the teeth 7 are in movable engagement. Several clamping rods 10 are fixedly connected to the outer surface of the rotating shaft 8. The other ends of the clamping rods 10 are fixedly connected to the clamping heads 11. Specifically, the first motor 16 drives the two extrusion plates 4 to move closer to each other, and the extrusion plates 4 move. The extrusion plates 4 drive the movable plate 3 to move. The teeth 7 on one side of the movable plate 3 engage with the transmission gear 9, causing the transmission gear 9 to rotate. The transmission gear 9 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the clamping rods 10 to rotate, so that the clamping heads 11 press against the top of the automotive parts.

[0024] In this embodiment, two L-shaped connecting plates are fixedly connected to the bottom outer surface of the base plate 1. An adjusting screw 12 is threaded through the outer surface of each of the two L-shaped connecting plates. A knob 13 is fixedly connected to the bottom outer surface of the adjusting screw 12, and an abutment plate 14 is rotatably connected to the top outer surface of the adjusting screw 12. Specifically, by passing the L-shaped connecting plates through both ends of the welding table, the knob 13 is rotated, which drives the adjusting screw 12 to rotate. The rotation of the adjusting screw 12 drives the abutment plate 14 to move, so that the abutment plate 14 abuts against the surface of the welding table with the base plate 1, thereby facilitating the installation of the device on the welding table.

[0025] In this embodiment, two side plates are fixedly connected to the top outer surface of the base plate 1, and a positive and negative lead screw 15 is rotatably connected between the two side plates. A first motor 16 is fixedly installed on the outer surface of the right side plate, and the output end of the first motor 16 is fixedly connected to the positive and negative lead screw 15. Two threaded plates 17 are threadedly connected to the outer surface of the positive and negative lead screw 15. Specifically, the first motor 16 drives the positive and negative lead screw 15 to rotate, and the positive and negative lead screw 15 drives the threaded plates 17 to move, moving the two rotating plates 2 to a position that matches the two automotive parts.

[0026] In this embodiment, electric push rods 18 are fixedly installed on the top outer surfaces of both threaded plates 17. The output end of the electric push rod 18 is fixedly connected to a mounting plate. Specifically, the electric push rod 18 is used to move the automotive parts to a suitable height.

[0027] In this embodiment, a support shaft 22 is rotatably passed through the outer surface of the mounting plate. The other end of the support shaft 22 is fixedly connected to the rotating plate 2. A second motor 21 is fixedly mounted on the outer surface of the mounting plate. A drive gear 23 is fixedly sleeved on the output end of the second motor 21. A driven gear 24 is fixedly sleeved on the outer surface of the support shaft 22. The outer surfaces of the drive gear 23 and the driven gear 24 are movably meshed. Specifically, the second motor 21 drives the drive gear 23 to rotate, which in turn drives the driven gear 24 to rotate, causing the support shaft 22 to rotate. This causes the rotating plate 2 to rotate the clamped automotive parts.

[0028] In this embodiment, L-shaped fixing plates are fixedly connected to both sides of the rotating plate 2. A cylinder 19 is fixedly installed on the outer surface of the L-shaped fixing plate. A pressing plate 20 is fixedly connected to the output end of the cylinder 19. Specifically, the cylinder 19 works and drives the pressing plate 20 to move, pressing the two ends of the automotive parts.

[0029] In this embodiment, two slide rods are fixedly connected between the two side plates, and two threaded plates 17 are respectively movably sleeved on the outer surface of the two slide rods. Specifically, when the positive and negative screws 15 rotate, they drive the threaded plates 17 to slide on the outer surface of the slide rods, so as to prevent the threaded plates 17 from rotating with the positive and negative screws 15.

[0030] In this embodiment, two limiting rods are movably passed through the outer surface of the L-shaped connecting plate. The other ends of the two limiting rods are fixedly connected to the abutment plate 14. Specifically, when the adjusting screw 12 is rotated, the limiting rods move accordingly, thereby limiting the abutment plate 14 and preventing the abutment plate 14 from rotating with the adjusting screw 12.

[0031] Working Principle: In use, the first motor 16 drives the positive and negative lead screws 15 to rotate, which in turn moves the threaded plate 17, moving the two rotating plates 2 to positions that match the two automotive parts. The two automotive parts to be welded are then placed on the two support plates 5. The first motor 16 is then turned on again, causing the two pressing plates 4 to move closer to each other. This movement of the pressing plates 4 moves the movable plate 3, and the teeth 7 on one side of the movable plate 3 mesh with the transmission gear 9, causing the transmission gear 9 to rotate. The transmission gear 9 then drives the rotating plate 3 to rotate. The shaft 8 rotates, which drives the clamping rod 10 to rotate, causing the clamping head 11 to press against the automotive part. The cylinder 19 works, which drives the clamping plate 20 to move, clamping both ends of the automotive part and holding it in place to prevent it from detaching during welding. This increases the stability of the automotive part during welding. Welding is then performed by the welding device. The second motor 21 drives the drive gear 23 to rotate, which in turn drives the driven gear 24 to rotate. The driven gear 24 then drives the support shaft 22 to rotate, thereby rotating the automotive part and performing all-around welding on the automotive part.

[0032] By passing the L-shaped connecting plate through both ends of the welding table, and by rotating the knob 13, the knob 13 drives the adjusting screw 12 to rotate, and the rotating adjusting screw 12 drives the abutment plate 14 to move, so that the abutment plate 14 abuts against the surface of the welding table with the base plate 1, thus making it easy to install the device on the welding table.

[0033] 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.
