The insertion rod 73 can position the adjustment plate, so as to prevent the adjustment disk 71 from rotating after adjustment. The arc plate 72 can be moved upward to drive the insertion rod 73 to separate from the adjustment disk 71.

[0025] refer to Figure 3 A connecting block 8 is fixedly connected to the top of the fixing plate 5 , and a connecting column 9 is fixedly connected to the front side of the connecting block 8 . The connecting column 9 and the first clamping plate 31 are on the same horizontal line.

[0026] As a technical optimization solution of the utility model, by setting the connecting block 8 and the connecting column 9, the upward movement of the fixed plate 5 can drive the connecting block 8 to move upward, and the upward movement of the connecting block 8 can drive the connecting column 9 to move upward. At the same time, the transmission rod 11 can drive the first clamping plate 31 and the second clamping plate 32 to move upward.

[0027] refer to Figure 3 A servo motor 10 is fixedly installed on the rear side of the connecting block 8, and a transmission rod 11 is fixedly connected to the output end of the servo motor 10.

The transmission rod 11 is movably connected to the connecting block 8 and the connecting column 9.

[0028] As a technical optimization solution of the present utility model, by providing a servo motor 10 and a transmission rod 11, starting the servo motor 10 can drive the output end of the servo motor 10 to drive the transmission rod 11 to rotate. The rotation of the transmission rod 11 can drive the first clamping plate 31 and the second clamping plate 32 to rotate, thereby facilitating the user to adjust the welding angle of the welding torch.

[0029] Reference Figure 2 , on the left and right sides of the front side of the arc plate 72, sliders 12 are fixedly connected. On the left and right sides of the bottom of the rear side of the support frame 2, sliding grooves 13 are opened. The surface of the slider 12 is slidably connected to the inner wall of the sliding groove 13.

[0030] As a technical optimization solution of the present utility model, by providing the slider 12 and the sliding groove 13, when the arc plate 72 moves upward, it can drive the slider 12 to move upward inside the sliding groove 13. The sliding groove 13 can limit the slider 12 and the arc plate 72 in the front, rear, left, and right directions, thereby improving the stability of the arc plate 72 driving the insertion rod 73 to move.

[0031] Reference Figure 1 , at the top of the front side of the support frame 2, a mounting plate 14 is fixedly connected. At the bottom of the mounting plate 14, a fan 15 is fixedly installed. At the rear side of the surface of the adjusting disc 71, a handle 16 is fixedly connected.

[0032] As a technical optimization solution of the present utility model, by providing the mounting plate 14, the fan 15, and the handle 16, the mounting plate 14 can fixedly limit the fan 15. By starting the fan 15, the welding torch clamped inside the first clamping plate 31 and the second clamping plate 32 can be cooled. The handle 16 facilitates the user to rotate and adjust the adjusting disc 71.

[0033] The working principle and use process of the utility model are as follows: when in use, the gun head of the welding robot welding gun is first placed on the inner side of the first clamping plate 31 and the second clamping plate 32, and then the first clamping plate 31 and the second clamping plate 32 are brought close to clamp and position the welding gun head by rotating the adjusting rotary rod 33. When the height of the welding gun head needs to be adjusted, the output end of the electric telescopic rod 4 is first started to drive the fixed plate 5 and the connecting block 8 to move upward. The upward movement of the connecting block 8 can use the connecting column 9 and the transmission rod 11 to drive the first clamping plate 31 and the second clamping plate 32 to move upward, thereby achieving the effect of height adjustment. When the welding angle of the welding gun head needs to be adjusted, , the servo motor 10 can be started so that the output end of the servo motor 10 drives the transmission rod 11 to rotate, and the rotation of the transmission rod 11 can drive the first clamping plate 31 and the second clamping plate 32 to rotate. When the horizontal angle of the welding gun needs to be adjusted, the arc plate 72 is first moved upward to make the insertion rod 73 disengage from the bottom plate 1 and the inside of the adjustment disk 71, and then the adjustment disk 71 is driven by the handle 16 to rotate to drive the support frame 2 to rotate. The rotation of the support frame 2 can drive the first clamping plate 31 and the second clamping plate 32 to rotate with the support frame 2 as the center, and the adjustment effect is better. At the same time, by starting the fan 15, the welding gun head inside the first clamping plate 31 and the second clamping plate 32 can be quickly cooled down.

[0034] To sum up: this welding robot welding gun fixing frame, by setting the electric telescopic rod 4 and the fixing plate 5, by starting the electric telescopic rod 4, the output end of the electric telescopic rod 4 can drive the fixing plate 5 to move upward, and the upward movement of the fixing plate 5 can drive the clamping mechanism 3 to move upward, which solves the problem that the existing welding gun fixing frame cannot adjust the gun head after positioning the welding gun, so that the welding gun can only weld the workpiece in a single direction, and the purchase and use of multiple welding guns for work will lead to increased economic costs, so it is inconvenient to use.
