After placing the plate to be welded on the placement rack 3, the servo motor 8 is controlled to work. When the servo motor 8 drives the winding wheel 26 to rotate, the first pull rope 21 and the third pull rope 25 can be reeled up. The first pull rope 21 can drive the clamping seat 18 to clamp and fix the plate. The third pull rope 25 can drive the second pull rope 22 to rotate the rotating seat 10.

After being controlled by the servo motor 8, the transmission roller 9 can rotate, thereby rotating the swivel 27, and the plate on the placement rack 3 can be flipped. Through the setting, the plate can be quickly flipped, thereby improving the welding efficiency.

[0030] The machine tool 1 is provided with a fixed seat 5, which is cylindrical in shape as a whole, a limit seat 6 is welded on the fixed seat 5, the limit seat 6 is vertically welded on the fixed seat 5, a guide rail 12 is welded on the limit seat 6, the guide rail 12 is annular in shape as a whole, and a slide seat 7 is slidably connected to the guide rail 12.

[0032] During implementation, by arranging a stand 4 on the machine tool 1, the stand 4 can restrict the swivel 27, and the swivel 27 can rotate in the guide groove 13 of the stand 4. After the placement rack 3 is welded on the swivel 27, the placement rack 3 will be vacated, thereby leaving enough space for flipping.

[0033] The inclined rod 31 is vertically arranged on the vertical rod 30, and a pull rod 33 is slidably connected to the inclined rod 31. The pull rod 33 is vertically arranged on the inclined rod 31. The inclined rod 31 and the pull rod 33 are arranged in a cross shape as a whole. The pull rod 33 is arranged in a T shape as a whole. A second pull rope 22 is arranged at one end of the pull rod 33, and a second spring 32 is sleeved on the pull rod 33. The inclined rod 31 can be connected to the vertical rod 30. When the inclined rod 31 is pulled, the vertical rod 30 will rotate, and finally the rotation of the rotating seat 10 is realized, and the transmission roller 9 on the rotating seat 10 can overlap with the rotating ring 27.

[0034] A guide groove 13 is provided on the stand 4, a swivel 27 is rotatably connected in the guide groove 13, a limit groove 28 is provided on the swivel 27, a limit frame 29 is slidably connected in the limit groove 28, the limit frame 29 is welded in the guide groove 13, the placement frame 3 on the swivel 27 is arranged in a herringbone shape as a whole, and a protrusion 17 is provided on the clamping seat 18 of the placement frame 3. The setting of the guide groove 13 can realize the restriction of the swivel 27, and the swivel 27 can be rotated on the stand 4, so that there will be no positional deviation.

[0035] A slide bar 15 is welded to the side frame 14 of the placement frame 3, and the slide bar 15 is horizontally arranged on the inner side of the placement frame 3. A moving seat 20 is slidably connected to the slide bar 15, and the moving seat 20 is welded to the clamping seat 18. The setting of the slide bar 15 can limit the moving seat 20, and the moving seat 20 can move along the slide bar 15. When the first pull rope 21 is connected to the moving seat 20, the moving seat 20 will be driven by the first pull rope 21 and move along the slide bar 15. When the moving seat 20 moves, it will drive the clamping seat 18 to move, and the clamping seat 18 can clamp and fix the plate, thereby limiting the plate and preventing the plate from being dislocated after flipping.

[0036] The movable seat 20 is rotatably connected with a guide wheel 19, which is rotatably connected to the placement frame 3, and a corresponding first spring 16 is sleeved on the slide bar 15 between the movable seat 20 and the side frame 14. By arranging the guide wheel 19 on the movable seat 20, the guide wheel 19 can move with the movable seat 20, and the movable seat 20 will not change position when moving.

[0037] One end of the first spring 16 is hung on the side frame 14, and the other end of the first spring 16 is hung on the moving seat 20. The moving seat 20 and the clamping seat 18 are arranged in an L shape as a whole. The first spring 16 can be arranged to reset the moving seat 20. When the moving seat 20 is pulled, it will squeeze the first spring 16. When the moving seat 20 is not pulled, the first spring 16 can drive the moving seat 20 to reset, thereby achieving the relaxation of the clamping seat 18, and the plate can be removed.

[0038] The clamping seat 18 is overlapped on the placing frame 3, and the protrusion 17 on the clamping seat 18 is arranged in a cone shape as a whole. The protrusion 17 can increase the friction between the plate, so that the plate can be more stable after being clamped.

[0039] In practice, by arranging a ball head 24 on the third pull rope 25, the ball head 24 can be installed on the connecting seat 23 of the second pull rope 22. When the placement frame 3 rotates with the rotating ring 27, the second pull rope 22 and the third pull rope 25 will rotate through the ball head 24, thereby preventing the second pull rope 22 from being entangled. A pull rod 33 is arranged on the second pull rope 22, and a second spring 32 is sleeved between the pull rod 33 and the inclined rod 31. When the second pull rope 22 is driven, the rotating seat 10 can be driven immediately. A space can be left between the pull rod 33 and the inclined rod 31 to prevent the small size from being entangled. When a small-inch plate is clamped, the second pull rope 22 is pulled out too much to prevent the second pull rope 22 from being torn off. The initial position of the transmission roller 9 on the rotating seat 10 is close to the transmission roller 9, so that when the clamping seat 18 moves a small range, the transmission roller 9 will also be connected to the swivel 27 to avoid the situation where the transmission cannot be achieved. A slide seat 7 is provided on the rotating seat 10, and the slide seat 7 can move on the guide rail 12 of the limit seat 6. A reset spring 11 is sleeved on the guide rail 12. The reset spring 11 pushes the slide seat 7 to reset, thereby ensuring that the rotating seat 10 is reset after being pulled, thereby achieving the next activity.

[0040] like Figure 1-7 As shown, a flipping method of a titanium alloy laser welding flipping device comprises the following steps:

[0041] S1: Place the plate to be welded on the placement rack 3, then control the servo motor 8 on the winding wheel 26 to start, and the winding wheel 26 will reel in the first pull rope 21 on the movable seat 20 during its rotation. As the reeling is reeled in, the movable seat 20 will move along the slide bar 15 toward the side frame 14, and the clamping seat 18 will be able to clamp and fix the plate;

[0042] S2: When the winding wheel 26 is wound, the third pull rope 25 will also be wound. After being wound, the third pull rope 25 will pull the second pull rope 22 to move, and the second pull rope 22 can drive the inclined rod 31 to rotate, and the vertical rod 30 on the inclined rod 31 can drive the rotating seat 10 to rotate, and the transmission roller 9 on the rotating seat 10 will move toward the position of the rotating ring 27, and the transmission roller 9 can drive the rotating ring 27 to rotate, and the plate on the placement rack 3 can be turned over.

[0043] The working principle of the present invention is as follows: by setting a stand 4 on the machine tool 1, the stand 4 can restrict the swivel 27, and the swivel 27 can rotate in the guide groove 13 of the stand 4. After the placement frame 3 is welded on the swivel 27, the placement frame 3 will be vacated, thereby leaving enough turning space. The placement frame 3 is provided with a side frame 14, and the servo motor 8 on the side frame 14 can be installed with a winding wheel 26. The winding wheel 26 can drive the first pull rope 21 and the third pull rope 25 to be wound. When the first pull rope 21 is wound, it will drive the clamping seat 18 to clamp the plate. When the third pull rope 25 is wound up, it will drive the second pull rope 22 to move, and the second pull rope 22 will drive the vertical rod 30 to rotate as a whole, and the rotating seat 10 will drive the transmission roller 9 to move to the position of the rotating ring 27, so as to overlap with the rotating ring 27. After overlapping, the servo motor 8 on the transmission roller 9 can be controlled to work, and the transmission roller 9 can drive the rotating ring 27 to rotate, so that the placement rack 3 can be turned over, so as to quickly weld the plates at different positions, thereby improving the welding efficiency. By arranging the ball head 24 on the third pull rope 25, the ball head The second pull rope 22 is connected to the rotating base 10 by the pull rod 33, and the third pull rope 25 is connected to the rotating base 10 by the pull rod 33. When the second pull rope 22 is driven, the rotating base 10 can be immediately driven by the pull rod 33. A space can be left between the pull rod 33 and the inclined rod 31 to prevent the second pull rope 22 from being entangled when clamping a small-sized plate. 2 is pulled out too much to prevent the second pull rope 22 from being torn off. The initial position of the transmission roller 9 on the rotating seat 10 is close to the transmission roller 9, so that when the clamping seat 18 moves slightly, the transmission roller 9 will also be connected to the rotating ring 27 to avoid the situation where the transmission cannot be achieved. The rotating seat 10 is provided with a slide seat 7, and the slide seat 7 can move on the guide rail 12 of the limiting seat 6. The guide rail 12 is sleeved with a reset spring 11, and the reset spring 11 pushes the slide seat 7 to reset, thereby ensuring that the rotating seat 10 is reset after being not pulled, so as to achieve the next activity.
