DETAILED DESCRIPTION

The double-axis adjustment component is used to accurately adjust the welding position. The double-axis adjustment component comprises a first sliding frame 13 and a second sliding frame 19. The first sliding frame 13 is fixedly connected to the top outer wall of the workbench 1. The middle inner wall of the first sliding frame 13 is rotatably connected to a first screw rod 14. The first screw rod 14 The outer wall of the first nut seat 17 is threadedly connected, the top outer wall of the first nut seat 17 is fixedly connected to the moving platform 18, the second sliding frame 19 is fixedly connected to the top outer wall of the moving platform 18, the middle inner wall of the second sliding frame 19 is rotatably connected to the second screw rod 20, the second screw rod 20 is perpendicular to the first screw rod 14, the outer wall of the second screw rod 20 is threadedly connected to the second nut seat 22, the welding platform 6 is fixedly connected to the top outer wall of the second nut seat 22, and the top outer wall of the welding platform 6 is installed with a fixing component for fixing the welding piece.

[0023] The dual-axis adjustment assembly also includes a first servo motor 15 and a second servo motor 21. The first servo motor 15 is fixedly mounted on an outer wall of one side of the first sliding frame 13, and its output shaft passes through the first sliding frame 13 and is fixedly connected to one end of the first screw rod 14. The second servo motor 21 is fixedly mounted on an outer wall of one side of the second sliding frame 19, and its output shaft passes through the second sliding frame 19 and is fixedly connected to one end of the second screw rod 20.

[0024] The outer wall of the first sliding frame 13 is slidably connected to two first sliders 16, and the two first sliders 16 are fixedly connected to the bottom outer wall of the moving platform 18. The outer wall of the second sliding frame 19 is slidably connected to two second sliders 23, and the two second sliders 23 are fixedly connected to the bottom outer wall of the welding platform 6.

[0025] The fixed component includes an electric cylinder 8 fixedly installed on the top outer wall of the welding platform 6, the output end of the electric cylinder 8 is fixedly connected to an L-shaped movable plate 9, the top outer wall of the L-shaped movable plate 9 is fixedly installed with a cylinder 10, the output end of the cylinder 10 passes through the L-shaped movable plate 9 and is fixedly connected to a pressure plate 11, and the bottom outer wall of the pressure plate 11 is provided with a rubber layer 12.

[0026] A positioning plate 7 is fixedly connected to the top outer wall of the welding platform 6 , and the positioning plate 7 is correspondingly parallel to the L-shaped movable plate 9 .

[0027] The top outer wall of the workbench 1 is fixedly connected to a frame 2 , a lifting mechanism 3 is installed on the outer wall of the frame 2 , and a plasma generator 4 is installed on the outer wall of the lifting mechanism 3 .

[0028] The implementation principle of the plasma welding mechanism for processing a single-head welding piece of a circuit breaker in the embodiment of the present application is as follows: in actual use, firstly, the welding piece to be welded is placed on the welding platform 6, and the electric cylinder 8 is started through the fixing assembly, and the output end of the electric cylinder 8 drives the L-shaped moving plate 9 to approach the welding piece and contact the welding piece to drive the welding piece to move, until the other end of the welding piece is pressed against the outer wall of the positioning plate 7 for limiting, and then the cylinder 10 is started, and the output end of the cylinder 10 drives the pressing plate 11 to press down to press the welding piece, and the rubber layer 12 will contact the welding piece before the pressing plate 11 presses the welding piece, and because the rubber layer 12 has a certain softness and elasticity, it can play a buffering and protective role to prevent the excessive squeezing of the pressing plate 11 from causing the welding piece to bend;

[0029] The two servo motors in the dual-axis adjustment assembly are precisely controlled by an external control unit (not shown in the figure), such as precisely controlling the speed and working state of the motors, and cooperating with two high-precision screws to achieve precise adjustment of the position of the positioning welding platform 6;

[0030] Specifically, by controlling the first servo motor 15 to start, the output shaft of the first servo motor 15 drives the first screw rod 14 to rotate on the inner surface thread of the first nut seat 17, and then drives the first nut seat 17 to slide along the outer wall of the first screw rod 14. At this time, the first nut seat 17 will drive the moving platform 18 to move forward and backward along the Y axis, and then drive the welding platform 6 to adjust the welding position of the Y axis. It is worth noting that when the moving platform 18 moves, it will drive the two first sliders 16 to slide on the outer wall of the first sliding frame 13, which plays a limiting role, so that the moving platform 18 always moves linearly and stably;

[0031] By controlling the second servo motor 21 to start, the output shaft of the second servo motor 21 drives the second screw rod 20 to rotate on the inner surface of the second nut seat 22, thereby driving the second nut seat 22 to slide along the outer wall of the second screw rod 20. At this time, the second nut seat 22 will drive the welding platform 6 to move left and right along the X-axis, thereby driving the welding platform 6 to adjust the welding position of the X-axis. It is worth noting that when the welding platform 6 moves, it will drive the two second sliders 23 to slide on the outer wall of the second sliding frame 19, which plays a limiting role, so that the welding platform 6 always moves linearly and stably;

[0032] After the welding position is located, the welding accuracy can be ensured. At this time, the height of the plasma generator 4 and the welding head 5 can be controlled by the lifting mechanism 3, and then the plasma generator 4 is started. The plasma generator 4 is used to generate a stable plasma arc, and a high-frequency oscillation circuit and a gas supply system are provided inside it (this is the prior art and will not be described in detail here). The high-frequency oscillation circuit generates a high-frequency electric field, so that the gas is ionized under the action of the electric field to form a plasma arc. The welding head 5 is made of a high-temperature resistant and corrosion-resistant alloy material with excellent thermal conductivity and mechanical strength. A plasma nozzle is provided inside the welding head 5 for spraying a plasma arc for welding.
