[0025] Please refer to Figures 1-4, the present utility model provides a technical solution: a double-station automatic welding device, including a base 1 and a welding robot 2. The welding robot 2 is installed at the center of the back of the base 1. On both sides of the top of the base 1, positioning components for two-way positioning of welding workpieces are installed. By setting two groups of positioning components, when the workpiece is placed on the base 1, the two groups of positioning components can position it from different directions respectively. In this way, when the welding robot 2 performs welding, the welding stability and welding efficiency are improved.

[0026] Further, the positioning component includes a first adjustment mechanism for longitudinal adjustment. The first adjustment mechanisms are respectively installed on both sides of the top of the base 1. The first adjustment mechanism includes a first housing 3. The first housings 3 are respectively installed on both sides of the top of the base 1. On one side inside the first housing 3, a first lead screw 4 is rotatably installed. One end of the first lead screw 4 rotatably extends to the outside of the first housing 3. A first motor 5 is installed outside the first housing 3. The power output end of the first motor 5 is connected to one end of the first lead screw 4. A first nut 6 is threadedly sleeved on the surface of the first lead screw 4. The top of the first nut 6 is provided with a first connecting block 7. The top of the first connecting block 7 slidably extends to the outside of the first housing 3 and is connected to the bottom of the second adjustment mechanism. By starting the first motor 5, the power output end of the first motor 5 drives the first lead screw 4 to rotate. While the first lead screw 4 rotates, it drives the first nut 6 to move. While the first nut 6 moves, it drives the first connecting block 7 to move.

[0027] Specifically, a second adjustment mechanism for lateral adjustment of the workpiece is installed on the top of the first adjustment mechanism. The second adjustment mechanism includes a second housing 8 installed on the top of the first connecting block 7. On the two sides inside the second housing 8, a second lead screw 9 is rotatably installed. The two ends of the second lead screw 9 rotatably extend to the outside of the second housing 8. A second motor 10 is installed outside the second housing 8. The power output end of the second motor 10 is connected to one end of the second lead screw 9. A second nut 11 is threadedly sleeved on the surface of the second lead screw 9. The top of the second nut 11 is provided with a second connecting block 12. The top of the second connecting block 12 slidably extends to the outside of the second housing 8 and is connected to the bottom of the third adjustment mechanism. By starting the second motor 10, the power output end of the second motor 10 drives the second lead screw 9 to rotate. While the second lead screw 9 rotates, it drives the second nut 11 to move. While the first nut 6 moves, it drives the second connecting block 12 to move.

[0028] Furthermore, a third adjusting mechanism for adjusting the positioning height of the workpiece is installed on the side of the second adjusting mechanism close to the welding robot 2, and the third adjusting mechanism is arranged corresponding to the welding end of the welding robot 2. The third adjusting mechanism includes a cross bar 13 installed on the top of the second connecting block 12. One end of the cross bar 13 close to the welding robot 2 is installed with a third housing 14. A third motor 15 is installed on the top of the inner cavity of the third housing 14. The power output end of the third motor 15 is installed with a third lead screw 16. The bottom of the third lead screw 16 is rotatably connected to the bottom of the inner cavity of the third housing 14. A third nut 17 is threadedly sleeved on the surface of the third lead screw 16. One side of the third nut 17 is installed with a third connecting block 18. One side of the third connecting block 18 slides and extends to the outside of the third housing 14 and is installed with a vertical plate 19.

The top of the bolt 21 is threadedly connected to the bottom of the vertical plate 19. A moving groove 22 adapted to the bolt 21 is formed in the horizontal plate 20. The bolt 21 is slidably inserted into the moving groove 22. By moving the horizontal plate 20, the position of the horizontal plate 20 can be adjusted. When one end of the horizontal plate 20 moves to the outside of the vertical plate 19, the bottom of the horizontal plate 20 can support the bottom of the workpiece clamped by the two vertical plates 19, further improving the stability of clamping the workpiece.

[0029] By starting the third motor 15, the power output end of the third motor 15 drives the third lead screw 16 to rotate. While the third lead screw 16 rotates, it drives the third nut 17 to move. While the third nut 17 moves, it drives the third connecting block 18 and the vertical plate 19 to move, so as to achieve the purpose of adjusting the height of the welded part.

[0030] It should be noted that after the vertical plate 19 and the horizontal plate 20 approach the welded part, they can clamp and position the welded part, thus facilitating the automatic welding of the welding robot 2. By setting the first adjusting mechanism, the longitudinal position movement of the vertical plate 19 and the horizontal plate 20 can be controlled. By setting the second adjusting mechanism, the second adjusting mechanism can control the lateral position movement of the vertical plate 19 and the horizontal plate 20. By setting the third adjusting mechanism, the up and down position adjustment of the vertical plate 19 and the horizontal plate 20 can be controlled, so as to facilitate the welding and positioning of the welded part.
