[0038] In specific application, the third motor 142 drives the telescopic structure 144 to rotate, and then the telescopic structure 144 drives the second fixed rod 143 to rotate around the third motor 142, and then the second fixed rod 143 drives the first fixed rod 13 to reciprocate through the annular sleeve 141, and then the first fixed rod 13 drives the middle block 12 to swing back and forth.

[0039] like Figure 5 , Figure 8 and Fig. 9 As shown, the telescopic structure 144 includes a first connecting cavity plate 1441, a second connecting plate 1442, a support plate 1443, a worm 1444, a fourth motor 1445, a turbine 1446 and a first rotating plate 1447; the driving end of the third motor 142 is fixedly connected to the first connecting cavity plate 1441, the inner cavity of the first connecting cavity plate 1441 is slidably connected to the second connecting plate 1442, the second connecting plate 1442 is rotatably connected to the second fixing rod 143, and the inner cavity side wall of the first connecting cavity plate 1441 is fixedly connected to two supporting plates 1443 parallel to each other.

[0040] In specific application, the fourth motor 1445 is started, and then the fourth motor 1445 drives the turbine 1446 to rotate through the worm 1444, and then the turbine 1446 drives the second connecting plate 1442 to slide through the first rotating plate 1447, and then the second connecting plate 1442 drives the second fixed rod 143 to move, thereby adjusting the distance between the second fixed rod 143 and the third motor 142, and then adjusting the swing amplitude of the welding gun 18.

[0041] like Figure 3 , Figure 6 and Figure 7 As shown, the offset measuring assembly 19 includes an offset base 191, a second rotating plate 192, a spring 193, a third rotating plate 194 and a rotating disk 195; two symmetrically distributed rotating disks 195 are rotatably connected between the two fixed blocks 21, and an angle sensor (not shown in the figure) is fixedly connected to the rotating disk 195; two symmetrically distributed offset bases 191 are fixedly connected to the outer wall of the fixed ring tube 17, and the offset bases 191 are rotatably connected to the second rotating plate 192, and a spring 193 is fixedly arranged between the second rotating plate 192 and the outer wall of the fixed ring tube 17, the second rotating plate 192 passes through the through slot 16 and is rotatably connected to the third rotating plate 194, and the other end of the third rotating plate 194 is rotatably connected to the rotating disk 195.

[0042] Furthermore, the inner bottom end of the through groove 16 is coplanar with the axial center line of the offset base 191, and the second rotating plate 192, the spring 193 and the through groove 16 cooperate to limit the end of the second rotating plate 192 away from the fixed block 21 to move only in the direction close to the welding gun 18.

[0043] In specific applications, when the second rotating plate 192 collides with the side wall of the workpiece, the end of the second rotating plate 192 away from the fixed block 21 moves toward the welding gun 18, and the other end of the second rotating plate 192 drives the turntable 195 to rotate through the third rotating plate 194, and then the rotation angle of the turntable 195 is measured by the angle sensor.

[0044] like Figure 7 As shown, the verification component 20 includes a slide groove 201, a slide plate 202, a fourth rotating plate 203 and a distance measuring sensor 204; two fixed blocks 21 are respectively provided with two slide grooves 201, the two slide grooves 201 on the same fixed block 21 are symmetrically distributed, and the slide grooves 201 on different fixed blocks 21 correspond to each other, and a slide plate 202 is slidably connected between the two corresponding slide grooves 201 on different fixed blocks 21, and the slide plate 202 is rotatably connected to the fourth rotating plate 203, and the other end of the fourth rotating plate 203 is rotatably connected to the corresponding turntable 195; wherein the inner walls of the two slide grooves 201 are fixedly connected to the distance measuring sensors 204, and the two slide grooves 201 are staggered with each other.

[0045] In specific application, the turntable 195 rotates, and then the turntable 195 pushes the slide plate 202 to slide in the slide groove 201 through the fourth rotating plate 203, so as to adjust the distance between the slide plate 202 and the distance measuring sensor 204, and then be recognized by the distance measuring sensor 204.

[0046] Furthermore, it also includes a controller (not shown in the figure) and a weld detection device (not shown in the figure), and the controller is electrically connected to the three-axis mobile frame 1, the ranging sensor 204, the angle sensor, the first motor 5, the second motor 9, the third motor 142, the fourth motor 1445 and the weld detection device.

[0047] It can be understood that the weld detection device is used to preliminarily identify the position trajectory of the weld; the controller receives the distance between the slide 202 and the distance sensor 204 respectively identified by the two distance measuring sensors 204, and then converts it into the offset angle corresponding to the welding gun 18 according to the difference between the two distances, and then compares it with the rotation angle of the angle sensor measuring turntable 195 received by the controller. If they are the same, it means that the rotation angle of the angle sensor measuring turntable 195 is correct, and then the controller controls the three-axis moving frame 1 and the third motor 142 to make the welding gun 18 rotate to the weld; if they are different, welding is stopped.

[0048] The working principle of the present invention is: the weld detection device preliminarily identifies the position trajectory of the weld, and then transmits it to the controller, and then controls the third motor 142 to drive the telescopic structure 144 to rotate, and then the telescopic structure 144 drives the second fixed rod 143 to rotate around the third motor 142, and then the second fixed rod 143 drives the first fixed rod 13 to reciprocate through the annular sleeve 141, and then the first fixed rod 13 drives the middle block 12 to swing back and forth, and then the middle block 12 drives the fixed ring cylinder 17 to swing perpendicular to the weld through the support frame 15, and then the fixed ring cylinder 17 drives the welding gun 18 to swing perpendicular to the weld, and the controller synchronously controls the second motor 9 to move, and the driving shaft of the second motor 9 drives the fan-shaped plate 8 to rotate along the direction of the weld through the fan-shaped teeth 10, and at the same time the controller three-axis moving frame 1 moves, so that the welding gun 18 is aligned with the weld and moves along the weld; as welding proceeds, the welding gun 18 may rub against or even collide with the workpiece during the welding process, so that the moving trajectory of the welding gun 18 deviates from the weld, To avoid this situation, when the second rotating plate 192 collides with the side wall of the workpiece, the end of the second rotating plate 192 away from the fixed block 21 moves toward the direction close to the welding gun 18, and the other end of the second rotating plate 192 drives the turntable 195 to rotate through the third rotating plate 194, and then the rotation angle of the turntable 195 is measured by the angle sensor, and then the turntable 195 pushes the slide plate 202 to slide in the slide groove 201 through the fourth rotating plate 203, thereby adjusting the distance between the slide plate 202 and the ranging sensor 204, and then it is recognized by the ranging sensor 204, and the controller receives the distance between the slide plate 202 and the ranging sensor 204 respectively recognized by the two ranging sensors 204, and then converts it into the offset angle corresponding to the welding gun 18 according to the difference between the two distances, and then compares it with the rotation angle of the turntable 195 measured by the angle sensor received by the controller. If they are the same, it means that the rotation angle of the turntable 195 measured by the angle sensor is correct, and then the three-axis moving frame 1 and the third motor 142 are controlled by the controller to make the welding gun 18 rotate the weld. In addition, when the swing amplitude needs to be adjusted, the fourth motor 1445 is started, and then the fourth motor 1445 drives the turbine 1446 to rotate through the worm 1444, and then the turbine 1446 drives the second connecting plate 1442 to slide through the first rotating plate 1447, and then the second connecting plate 1442 drives the second fixed rod 143 to move, thereby adjusting the distance between the second fixed rod 143 and the third motor 142, and then adjusting the swing amplitude of the welding gun 18.
