[0006] Preferably, the outer wall of the first tray is in contact with the inner wall of the first fixing frame, and the outer wall of the second tray is in contact with the inner wall of the second fixing frame.

[0007] Preferably, the first tray is slidably connected to the slide groove via an anti-detachment rod and an anti-detachment groove, wherein the outer wall of the anti-detachment rod is in contact with the inner wall of the anti-detachment groove.

[0008] Preferably, both the first and second fixed frames are provided with an installation mechanism at their tops. The installation mechanism includes a bracket, a pin, an anti-detachment ring, a fixing rod, an installation groove, an installation block, a slot, and a protective plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, this auxiliary equipment for laser welding machines places two metal plates inside the first and second fixed frames, respectively, on top of the first and second support plates. Then, by tightening the bolts, the second support plate is pushed upwards. The first support plate, through the design of anti-disengagement rods and anti-disengagement sliding grooves, moves upwards when the second support plate is lifted, thus clamping and fixing the two metal plates together with the guard plate. Then, a motor drives a bidirectional lead screw, causing the first and second clamping plates to move closer together, thereby clamping and fixing the two metal plates. The clamping mechanism facilitates welding at the connection points. The first and second support plates ensure that the tops of two metal plates of the same thickness are on the same horizontal plane during butt jointing, providing a lifting effect for better connection. When fixing the metal plates, the guard plate increases friction for better clamping and fixation. For long-term use, when the guard plate needs to be replaced, the pin can be pulled upwards. One end of the pin disengages from the pin hole at the top of the fixing rod, allowing the fixing rod to slide out and the other end of the fixing rod to disengage from the slot, thus enabling the replacement of the guard plate. The anti-disengagement ring prevents the pin from being lost. Attached Figure Description

[0017] Example

[0018] Please see Figure 1-4This utility model discloses an auxiliary device for a laser welding machine, comprising a base 1, a fixing groove 2 on the top of the base 1, a bidirectional lead screw 4 rotatably connected to the inner side of the fixing groove 2, and a first clamping plate 5 and a second clamping plate 6 threadedly connected to the outer side of the bidirectional lead screw 4. A clamping mechanism is provided on the top of the first clamping plate 5 and the second clamping plate 6, the clamping mechanism including a first fixing frame 7, a limiting post 8, a first support plate 9, an anti-detachment rod 10, a second fixing frame 11, a bolt 12, a second support plate 13, a sliding groove 14, and an anti-detachment groove 15. The first fixing frame 7 is fixedly connected to the top of the first clamping plate 5, the limiting post 8 is fixedly connected to the inner side of the first fixing frame 7, the first support plate 9 is slidably connected to the outer side of the limiting post 8, and the anti-detachment rod 10 is fixedly connected to the outer side of the first support plate 9. The second fixing frame 11 is fixedly connected to the top of the second clamping plate 6, the bolt 12 is threadedly connected to the bottom of the second fixing frame 11, and the second support plate 13 is rotatably connected to one end of the bolt 12. A groove 14 is provided at the top of one end of the slide 14, and an anti-detachment groove 15 is provided on the inner side wall of the groove 14. In use, two metal plates are placed inside the first fixed frame 7 and the second fixed frame 11, respectively, and placed on top of the first support plate 9 and the second support plate 13. Then, the bolt 12 is turned to push the second support plate 13 upward. The first support plate 9 is slidably inserted into the groove 14 through the anti-detachment rod 10 and the anti-detachment groove 15. When the second support plate 13 is lifted, the first support plate 9 is driven upward, and together with the guard plate 23, the two metal plates are clamped and fixed. Then, the motor 3 drives the bidirectional lead screw 4 to bring the first clamping plate 5 and the second clamping plate 6 closer together, thereby clamping the two metal plates together and facilitating subsequent welding at the connection point. The arrangement of the first support plate 9 and the second support plate 13 can ensure that the tops of the two metal plates of the same thickness are on the same horizontal plane when they are joined, and can also play a supporting role to achieve a better joining effect.

[0019] Furthermore, a motor 3 is fixedly connected to one side of the base 1, and one end of the output shaft of the motor 3 is fixedly connected to one end of the bidirectional lead screw 4. The outer wall of one end of the first clamping plate 5 and the second clamping plate 6 is in contact with the inner wall of the fixing groove 2.

[0020] Furthermore, the outer wall of the first tray 9 is in contact with the inner wall of the first fixing frame 7, and the outer wall of the second tray 13 is in contact with the inner wall of the second fixing frame 11.

[0021] Furthermore, the first support plate 9 is slidably inserted into the slide groove 14 via the anti-detachment rod 10 and the anti-detachment groove 15, with the outer wall of the anti-detachment rod 10 fitting against the inner wall of the anti-detachment groove 15.

[0022] To facilitate the replacement of the protective plate 23, both the first fixing frame 7 and the second fixing frame 11 are equipped with a mounting mechanism at their tops. The mounting mechanism includes a bracket 16, a pin 17, an anti-detachment ring 18, a fixing rod 19, a mounting groove 20, a mounting block 21, a slot 22, and a protective plate 23. The bracket 16 is fixedly connected to the top of both the first fixing frame 7 and the second fixing frame 11. The pin 17 is slidably inserted into the top of the bracket 16. The anti-detachment ring 18 is fixedly connected to the outer side of the pin 17. The fixing rod 19 is inserted into one side of the bracket 16. The tops of both the first fixing frame 7 and the second fixing frame 11 are provided with mounting grooves. 20. A mounting block 21 is inserted into the bottom of the mounting slot 20. A slot 22 is provided on one side of the mounting block 21. A protective plate 23 is integrally formed on the bottom of the mounting block 21. When fixing the metal plate, the protective plate 23 can increase friction and better clamp and fix it. When the protective plate 23 needs to be replaced after long-term use, the pin 17 can be pulled upward. One end of the pin 17 will disengage from the pin hole at the top of the fixing rod 19, and the fixing rod 19 can be slid out. One end of the fixing rod 19 will disengage from the slot 22, thereby replacing the protective plate 23. The anti-disengagement ring 18 can prevent the pin 17 from being lost.

[0023] Furthermore, both the mounting block 21 and the protective plate 23 are made of rubber, and the fixing rod 19 slides into the slot 22.

[0024] Working principle: In use, two metal plates are placed inside the first fixing frame 7 and the second fixing frame 11, respectively, and placed on top of the first support plate 9 and the second support plate 13. Then, the bolt 12 is tightened, which pushes the second support plate 13 upward. The first support plate 9, through the anti-disengagement rod 10 and the anti-disengagement groove 15 slidingly inserted into the sliding groove 14, moves upward when the second support plate 13 is lifted, thereby clamping and fixing the two metal plates together with the guard plate 23. Then, the motor 3 drives the bidirectional lead screw 4, which brings the first clamping plate 5 and the second clamping plate 6 closer together, thereby clamping and connecting the two metal plates for subsequent connection. The welding process, with the first support plate 9 and the second support plate 13, ensures that the tops of the two metal plates of the same thickness are on the same horizontal plane when they are joined, and also provides a lifting effect for better joining. When fixing the metal plates, the guard plate 23 increases friction and provides better clamping and fixing. When the guard plate 23 needs to be replaced after long-term use, the pin 17 can be pulled upwards, and one end of the pin 17 will disengage from the pin hole at the top of the fixing rod 19, allowing the fixing rod 19 to slide out. One end of the fixing rod 19 will disengage from the slot 22, thus allowing the guard plate 23 to be replaced. The anti-disengagement ring 18 prevents the pin 17 from being lost.
