[0025] Through the provision of an automatic grounding device for a CO2 welding machine in the embodiments of the present application, the problem that before welding, it is necessary to manually ground the welding machine, but there is a situation of human negligence resulting in forgetting to ground, leading to major accidents, is solved. By rotating the lead screw 203, the moving seat 201 is driven to move, so that the moving seat 201 is separated from the pusher on the support frame 1. At this time, it is convenient to install a wire spool in the wire feeding mechanism on the moving seat 201, enabling normal welding. When the moving seat 201 moves, the rotating rod 302 is driven to rotate, causing the displacement seat 301 to move accordingly, and the rotating seat 304 to move downward, driving the grounding rod 305 to contact the ground to complete automatic grounding.

[0026] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation modes.

[0027] The embodiments of the present utility model disclose an automatic grounding device for a CO2 welding machine.

[0028] According to the attached Figures 1-3 As shown, it includes a support frame 1 and a moving unit 2. The moving unit 2 is located on the support frame 1.

[0029] The moving unit 2 includes a fixed seat 202 fixedly connected to the support frame 1. A lead screw 203 is rotatably connected to the inner wall of the support frame 1. One end of the lead screw 203 is rotatably connected to the fixed seat 202. By rotating the lead screw 203, the moving seat 201 is driven to move, so that the moving seat 201 is separated from the pusher on the support frame 1. At this time, it is convenient to install a wire spool in the wire feeding mechanism on the moving seat 201, enabling normal welding.

[0030] A rotating unit 3 is provided in the moving unit 2. The rotating unit 3 includes a displacement seat 301. The displacement seat 301 is located between the fixed seat 202 and the moving seat 201. A grounding rod 305 is provided below the displacement seat 301. When the moving seat 201 moves, the rotating rod 302 is driven to rotate, causing the displacement seat 301 to move accordingly, and the rotating seat 304 to move downward, driving the grounding rod 305 to contact the ground to complete automatic grounding.

[0031] On both sides of the displacement seat 301, there are fixed units 4. The fixed unit 4 includes a fixing frame 401 fixed on both sides of the displacement seat 301. Below the fixing frame 401, there is a grounding block 403. When the displacement seat 301 moves, it drives the fixing frame 401 to move, and then drives the sliding rod 402 and the grounding block 403 to move. When the grounding block 403 contacts and presses against the ground, at this time, the sliding rod 402 slides along the inner wall of the fixing frame 401, compressing the spring 404. Under the rebound of the spring 404, the grounding block 403 contacts the ground, ensuring the stability of the support frame 1.

[0032] A welding machine main body is fixedly installed on the fixed seat 202, and a wire feeding mechanism is fixedly installed on the moving seat 201. Welding is performed through the welding machine main body. Before welding, by moving the moving seat 201, the wire feeding mechanism is driven to move, and then the wire reel can be installed, facilitating welding.

[0033] Rotating rods 302 are rotatably connected to both ends of the displacement seat 301.

[0034] The other end of the rotating rod 302 is rotatably connected to a connecting seat 303. The connecting seat 303 is fixedly connected to the corresponding fixed seat 202 and moving seat 201. When the moving seat 201 moves, it drives the rotating rod 302 to rotate, driving the displacement seat 301 to move.

[0035] A rotating seat 304 is rotatably connected to the bottom end face of the displacement seat 301. The rotating seat 304 is fixedly connected to the grounding rod 305. Under the movement of the displacement seat 301, the rotating seat 304 moves downward, driving the grounding rod 305 to contact the ground. At the same time, a torsion spring is provided inside the rotating seat 304 to ensure the stability of the contact between the grounding rod 305 and the ground.

[0036] A sliding rod 402 is slidably connected to the inner wall of the fixing frame 401.

[0037] The bottom end face of the sliding rod 402 is fixedly connected to the grounding block 403. When the displacement seat 301 moves, it drives the fixing frame 401 to move, and then drives the sliding rod 402 and the grounding block 403 to move.

[0038] The top end face of the grounding block 403 is fixedly connected to a spring 404. The other end of the spring 404 is fixedly connected to the fixing frame 401. When the grounding block 403 contacts and presses against the ground, at this time, the sliding rod 402 slides along the inner wall of the fixing frame 401, compressing the spring 404. Under the rebound of the spring 404, the grounding block 403 contacts the ground, ensuring the stability of the support frame 1.
