[0024] Specifically, first place the workpiece to be processed on the top of the support 2, then, through the output end of the cylinder 4, the two ends of the slide bar 5 slide inside the bottom plate 3, and use the sliding of the slide bar 5 to push one end of the scissor-type bracket 6 to move. As the scissor-type bracket 6 gradually extends, the support 2 moves up and down inside the workbench 1, thereby realizing the height positioning of the workpiece, and then the output end of the motor 8 drives the gear 9 to rotate. Due to the close engagement between the gear 9 and the rack 10, the rack 10 moves with the rotation of the gear 9. In this process, the L-shaped connecting plate 11 plays a key role, connecting the rack 10 and the fixed plate 13, thereby driving the fixed plate 13 and the welding head to move together. In order to ensure the accuracy and stability of the movement, the whole process is guided by the guide rail 12, and finally, by driving the support frame 7 to slide on the top of the workbench 1, the final positioning of the welding head is realized, ensuring the efficiency and accuracy of the welding process.

[0025] Reference Figure 1 and Figure 4 The bottom of the support frame 7 is fixedly connected with a triangular fixing seat 14, the interior of the support 2 is fixedly connected with a fixing plate 2 15, the interior of the fixing plate 2 15 is fixedly connected with a motor 2 16, the output end of the motor 2 16 is fixedly connected with a driving wheel 17, the interior of the fixing plate 2 15 is rotatably connected with a double-sided gear ring 18, the double-sided gear ring 18 is meshed with the driving wheel 17, the interior of the fixing plate 2 15 is rotatably connected with a driven wheel 19, the driven wheel 19 is meshed with the double-sided gear ring 18, the interior of the fixing plate 2 15 is slidably connected with a rack 20, the rack 20 is meshed with the driven wheel 19, the outer wall of the rack 20 is fixedly connected with a connecting seat 21, the upper surface of the connecting seat 21 is fixedly connected with a clamping plate 22, and the outer wall of the clamping plate 22 is fixedly connected with a rubber pad 23;

[0026] Specifically, the output end of the motor 2 16 is tightly connected with the driving wheel 17. When the motor 2 16 is started, its power will be transmitted to the driving wheel 17 through the output end, causing it to start rotating. Then, through the engagement with the double-sided gear ring 18, the double-sided gear ring 18 is further driven to rotate inside the fixed plate 2 15, thereby realizing the power transmission from the driving wheel 17 to the driven wheel 19. As the double-sided gear ring 18 rotates, the three driven wheels 19 inside the fixed plate 2 15 also start to rotate. The driven wheel 19 cooperates with the rack 20. When the driven wheel 19 rotates, the rack 20 will slide inside the fixed plate 2 15. Next, the rotation of the driven wheel 19 drives the movement of the clamping plate 22 through the connecting seat 21, converting the rotation of the driven wheel 19 into the linear motion of the clamping plate 22. Finally, during the movement of the clamping plate 22, the rubber pad 23 is used to clamp the workpiece.

[0027] Working principle: When the positioning device for powder plasma welding is needed, the workpiece is first placed on the upper surface of the support 2, and then the output end of the cylinder 4 drives the two ends of the slide rod 5 to slide inside the bottom plate 3, thereby pushing one end of the scissor-type bracket 6 to move, so that the scissor-type bracket 6 gradually extends, and then pushes the support 2 to move up and down inside the workbench 1 to achieve the height positioning of the workpiece, and then the output end of the motor 8 drives the gear 9 to rotate. Due to the meshing of the gear 9 and the rack 10, the rack 10 moves with the rotation of the gear 9, thereby driving the fixed plate 13 to move through the L-shaped connecting plate 11, and then driving the welding head The moving process is guided by the guide rail 12, and finally the support frame 7 can be driven to slide on the top of the workbench 1, so as to realize the positioning of the welding joint, and then the output end of the motor 2 16 drives the driving wheel 17 to rotate, thereby driving the double-sided gear ring 18 to rotate inside the fixed plate 2 15, and then the rotation of the double-sided gear ring 18 drives the three driven wheels 19 inside the fixed plate 2 15 to rotate, and then drives the three racks 20 to slide inside the fixed plate 2 15, and then the driven wheel 19 drives the clamping plate 22 to move through the connecting seat 21, and finally cooperates with the rubber pad 23 to clamp the workpiece, thereby achieving a fixing effect.
