[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The embodiments of the present application disclose an adjustable welding mechanism.

[0023] Reference Figure 1 and Figure 2The adjustable welding mechanism includes a mounting frame 1, a first sliding frame 2 is slidingly connected to the mounting frame 1, a first driving device for driving the first sliding frame 2 to slide is provided on the mounting frame 1, a second sliding frame 3 is slidingly connected to the first sliding frame 2, a second driving device for driving the second sliding frame 3 to slide is provided on the first sliding frame 2, the moving directions of the first sliding frame 2 and the second sliding frame 3 are perpendicular to each other, a support frame 5 is slidingly connected to the second sliding frame 3, a welding machine 4 is arranged on the support frame 5, a cover shell 8 is bolted to the support frame 5, the welding machine 4 is installed in the cover shell 8, an observation port is opened on the cover shell 8, the observation port 24 corresponds to the screen of the welding machine 4, which is convenient for the operator to observe the status information of the welding machine 4 in time, and a lifting device for driving the support frame 5 to rise and fall is provided on the second sliding frame 3.

[0024] Therefore, the first driving device is started to drive the first sliding frame 2 to slide on the mounting frame 1, and the second sliding frame 3 is started to drive the second sliding frame 3 to slide on the first sliding frame 2, so that the welding machine 4 is displaced. Since the moving directions of the first sliding frame 2 and the second sliding frame 3 are perpendicular to each other, multi-directional displacement of the welding machine 4 in the horizontal direction can be achieved. The lifting device is started to drive the support frame 5 to slide on the second sliding frame 3, so that displacement of the welding machine 4 in the vertical direction can be achieved, which increases the adjustable range of the welding machine 4 during welding, makes it more flexible, and improves the welding efficiency of the workpiece.

[0025] Reference Figure 1 and Figure 2 The first driving device includes a first driving motor 6 arranged on the mounting frame 1, and a first screw rod 7 is installed at the output end of the first driving motor 6. The first screw rod 7 is rotatably connected to the mounting frame 1. The outer edge of the first screw rod 7 is threadedly connected to the first nut, and the first sliding frame 2 is arranged on the first nut.

[0026] Therefore, the first drive motor 6 is started, driving the first screw rod 7 at the output end of the first drive motor 6 to rotate, thereby driving the first nut to reciprocate along the direction of the first screw rod 7, thereby achieving horizontal displacement of the first sliding frame 2. In the embodiment of the present application, a slide rail 21 arranged parallel to the first screw rod 7 can be provided on the mounting frame 1. A guide block 22 of matching size with the slide rail 21 is slidably connected to the slide rail 21. The first sliding frame 2 is bolted to the guide block 22. The slide rail 21 acts as a limit on the movement of the guide block 22, thereby reducing the possibility of positional deviation of the first sliding frame 2 and improving the stability of the first sliding frame 2 during movement.

[0027] Reference Figure 1 and Figure 3The second drive device includes a second screw rod 9 rotatably connected to the first sliding frame 2. In the embodiment of the present application, the second screw rod 9 and the first screw rod 7 are arranged perpendicular to each other. The first sliding frame 2 is provided with a second drive motor 10, which is transmission-connected to the second screw rod 9 via a connecting assembly. The outer edge of the second screw rod 9 is threadedly connected to a second nut 11, and the second sliding frame 3 is mounted on the second nut 11. A guide rail 16 is provided in the first sliding frame 2, which is arranged parallel to the second screw rod 9. A slider 17 matching the guide rail 16 is slidably connected to the guide rail 16. The second sliding frame 3 is mounted on the slider 17. The guide rail 16 limits the movement position of the slider 17, reducing the possibility of positional deviation of the second sliding frame 3 and improving the stability of the second sliding frame 3 during movement.

[0028] Reference Figure 1 and Figure 3 The connecting assembly includes a first transmission wheel 12 disposed at the output end of the second drive motor 10, a second transmission wheel 13 mounted at one end of the second screw rod 9, and a conveyor belt 14 tightly wound between the first transmission wheel 12 and the second transmission wheel 13. The outer edges of the first transmission wheel 12 and the second transmission wheel 13 are fixedly connected to a plurality of ribs, and the conveyor belt 14 is tightly wound around the outer edges of the ribs. The ribs reduce the possibility of slippage between the conveyor belt 14 and the first and second transmission wheels 12 and 13, allowing the power of the first transmission wheel 12 to be smoothly transmitted to the conveyor belt 14 and the second transmission wheel 13, thereby improving the stability of the conveyor belt 14 during operation.

[0029] Therefore, the second drive motor 10 is started to rotate the first transmission wheel 12 at the output end of the second motor, driving the transmission belt and the second transmission wheel 13 to rotate synchronously, thereby driving the second screw 9 to rotate, thereby driving the second nut 11 to move back and forth along the direction of the second screw 9, realizing the horizontal displacement of the second sliding frame 3. Since the movement directions of the first sliding frame 2 and the second sliding frame 3 are perpendicular to each other, multi-directional displacement of the welding machine 4 in the horizontal direction can be achieved. In the embodiment of the present application, the second drive motor 10 is located above the first drive motor 6 and the central axes of the two are arranged vertically, which has a compact structure, reduces the usable space occupied by the overall welding mechanism, and further optimizes space utilization by using the connecting assembly, the first drive device and the second drive device to meet the welding needs in a small space.

[0030] Reference Figure 1 and Figure 4 The lifting device includes a third screw rod 18 rotatably connected to the second sliding frame 3. In the embodiment of the present application, the third screw rod 18 is vertically arranged, and the outer edge of the third screw rod 18 is threadedly connected to a third nut. The support frame 5 is bolted to the third nut. A handwheel 20 is rotatably connected to the second sliding frame 3, and the handwheel 20 is fixedly sleeved on the end of the third screw rod 18 away from the first sliding frame 2.

[0031] Therefore, the operator turns the handwheel 20 to drive the third screw rod 18 to rotate, so that the third nut moves back and forth along the direction of the third screw rod 18, realizing the vertical displacement of the support frame 5, facilitating the adjustment of the height of the welding machine 4 and the workpiece on the support frame 5, and having greater flexibility.

[0032] Reference Figure 1 and Figure 4 A mounting plate 19 is provided on the third nut, and a reinforcing rib 23 is provided between the mounting plate 19 and the third nut. The reinforcing rib 23 improves the structural rigidity and load of the mounting plate 19, and improves the stability of the mounting plate 19 when it moves. A waist-shaped hole 15 is opened on the mounting plate 19, and the support frame 5 is provided with a mounting bolt that passes through the support frame 5 and the waist-shaped hole 15 in sequence. The outer edge of the mounting bolt is threadedly connected to the mounting nut, and the mounting plate 19 is tightly pressed between the mounting bolt and the mounting nut.

[0033] Therefore, the operator can use the bolt disassembly method to remove the support frame 5 from the mounting plate 19, which is convenient for subsequent replacement of welding machines 4 of different models and sizes while facilitating the disassembly of the welding machine 4 for subsequent maintenance. Since a waist-shaped hole 15 is provided on the mounting plate 19, it is convenient to adjust the position of the support frame 5 installed on the mounting plate 19.

[0034] The implementation principle of the embodiment of the present application is as follows: the operator rotates the handwheel 20 to drive the third screw rod 18 to rotate, thereby causing the third nut to reciprocate in the direction of the third screw rod 18 to realize the vertical displacement of the support frame 5; starting the first drive motor 6 drives the first screw rod 7 at the output end of the first drive motor 6 to rotate, thereby driving the first nut to reciprocate in the direction of the first screw rod 7 to realize the horizontal displacement of the first sliding frame 2; starting the second drive motor 10 to rotate the first transmission wheel 12 at the output end of the second motor, driving the transmission belt and the second transmission wheel 13 to rotate synchronously, thereby driving the second screw rod 9 to rotate, thereby driving the second nut 11 to reciprocate in the direction of the second screw rod 9 to realize the horizontal displacement of the second sliding frame 3. Since the moving directions of the first sliding frame 2 and the second sliding frame 3 are perpendicular to each other, multi-directional displacement of the welding machine 4 in the horizontal direction can be realized, which improves the adjustable range of the welding machine 4 during welding, is more flexible, and improves the welding efficiency of the workpiece.
