[0026] Specifically: the lead screw mechanism 301 is driven to rotate by the stepper motor 9, and a bearing structure is provided on the other side. The lead screw mechanism 301 can drive the guide frame 4.

[0027] An insulating sleeve 21 is fixedly connected to the outside of the welding torch tee assembly 19. Two clamps 24 are symmetrically locked on the outside of the insulating sleeve 21. One side of the clamp 24 is fixedly connected to the output end of the reducer 29.

[0028] Specifically: Rotating the small corrugated handwheel 13 allows for fine adjustment of the angle of the conductive rod holder 24.

[0029] The clamp 24 is capable of clamping the welding torch tee assembly 19.

[0030] The inner side of the constraint block 25 is threaded with a third bolt 26, and the lower end of the third bolt 26 is correspondingly locked with a constraint shaft clamping plate 23. The constraint shaft clamping plate 23 and the output end of the reducer 29 are in contact with each other.

[0031] Specifically: the third bolt 26 can be used to install and adjust the constraint shaft clamping plate 23.

[0032] A handwheel 13 is provided on the other side of the reducer 29. A second bolt 22 is threaded between one side of the handwheel 13 and the reducer 29. The handwheel 13 and the input end of the reducer 29 are fixedly connected.

[0033] Specifically: the second bolt 22 is used to lock the handwheel 13.

[0034] Two shims 6 are symmetrically arranged on both sides of the adjusting plate 14. A first bolt 12 is arranged on one side of the shim 6. The first bolt 12 is threadedly connected to the outer side of the fixed shaft 28.

[0039] Specifically: The proximity switch 10 is a position switch that can be operated without direct mechanical contact with moving parts. When an object approaches the sensing surface of the switch 10 to the operating distance, the switch can be activated without mechanical contact or pressure, thereby driving DC electrical appliances or providing control commands to computer devices. The proximity switch 10 is a switch-type sensor (i.e., a contactless switch). It has the characteristics of limit switches and micro switches, as well as sensing performance. It is reliable, stable, has a fast frequency response, long service life, strong anti-interference ability, and is waterproof, shockproof, and corrosion-resistant. When the proximity switch 10 detects the signal of the distance to the adjustment plate 14, it feeds back to the stepper motor 9. The rotation of the stepper motor 9 drives the lead screw mechanism 301 in the hand-cranked slide 3, thereby driving the guide frame 4 to move left and right, so that the guide wheel 17 always tracks the weld.

[0040] A floating joint 7 is fixedly connected to the lower end of the cylinder 5, and the floating joint 7 is fixedly connected to the upper end of the moving block 2.

[0041] Specifically: the floating joint 7 is connected between the cylinder 5 and the guide arc frame moving block 2.

[0042] Working principle: First, the angle of the conductive rod holder 24 is manually fine-tuned using the small corrugated handwheel 13. The conductive rod insulating sleeve 21 is fixed on the conductive rod holder 24, ensuring that the conductive nozzle inside the welding torch tee assembly 19 and the guide wheel 17 are in a straight line. The constraint shaft clamp 23 is fixed on the reducer 29. By adjusting the third bolt 26, the constraint block 25 of the reducer 29 is tightened, thereby limiting the shaft rotation of the reducer 29 output shaft due to internal gear clearance, thus ensuring the stability of the welding torch tee assembly 19 and the guide wheel 17. Two proximity switches 10 are fixed on the fixed frame 8. When the proximity switch 10 detects the signal of the distance of the adjustment plate 14, it feeds back to the stepper motor 9. The rotation of the stepper motor 9 drives the screw mechanism 301 in the hand-cranked slide table 3, thereby driving the guide frame 4 to move left and right, so that the guide wheel 17 always tracks the weld seam. The linear guide rail 20 is installed on the guide frame 4, the cylinder 5 is installed on the guide frame 4, and the slider 1 is installed on the guide arc frame movement. On block 2, the floating joint 7 is connected between the cylinder 5 and the guide arc frame moving block 2. The piston in the cylinder 5 moves up and down according to the height of the weld seam to ensure that the welding torch tee assembly 19 and the guide wheel 17 are at the same height. This device is a flexible mechanism. Two springs 11 are threaded on the fixed shaft 28, which is fixed to the connecting plate 27. The adjusting plate 14 is fixed to the reducer 29 fixed plate 18. The first bolt 12 adjusts the distance between the shims 6. The fixed plate 18 is fixed to the upper and lower connecting transition piece 15, which is connected to the connecting piece 16. According to the straightness of the weld seam, the two guide wheels 17 swing left and right, thereby driving the adjusting plate 14 to swing left and right. This causes the shims 6 to compress the two springs 11 to generate flexible constraints. When the distance deviation of the adjusting plate 14 is large, the two proximity switches 10 provide feedback signals to drive the stepper motor 9 to perform the action. The entire welding torch tee assembly 19 and the guide wheel 17 maintain consistency in height and direction, thereby achieving a stable weld seam tracking effect.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
