The transmission semi-ring rack 6 is clamped to the production rack 1 through the limiting semi-circular rack 7. An arc-shaped rack 10 is fixedly connected to the inner side of the transmission semi-ring rack 6. In order to facilitate the rotation of the welding gun 8 along with the transmission semi-ring rack 6, the top end of the fixing member 9 is fixedly connected to the limiting semi-circular rack 7.

[0024] The transmission mechanism includes a transmission column 11, a first belt seat 12 and a transmission gear 13. In order to facilitate driving the transmission semi-ring rack 6 to rotate around the central axis of the semi-circular welding rack 5 on the semi-circular welding rack 5, transmission columns 11 are rotatably connected to the inside of the top end and the bottom end of the semi-circular welding rack 5 respectively. The end of the transmission column 11 away from the production rack 1 is fixedly connected to the first belt seat 12. The first belt seat 12 is meshed with the arc-shaped rack 10, thereby facilitating the rotation of the transmission semi-ring rack 6 in the semi-circular welding rack 5 through the arc-shaped rack 10. The end of the transmission column 11 close to the production rack 1 is fixedly connected to the transmission gear 13.

[0025] The transmission mechanism further includes a first connecting column 14, a first servo motor 15, a second belt seat 16, a second connecting column 17, a third belt seat 18 and a transmission belt 22. The first connecting column 14 is rotatably connected to the inside of the semi-circular welding frame 5 near the fixed frame 4. To facilitate driving the first connecting column 14 to rotate, a first servo motor 15 is fixedly connected to the outer side of the semi-circular welding frame 5 at a position corresponding to the first connecting column 14. The output end of the first servo motor 15 is fixedly connected to the first connecting column 14. A second belt seat 16 is fixedly connected to the ring side of the first servo motor 15. A second connecting column 17 is arranged inside the semi-circular welding frame 5 at a position corresponding to the first connecting column 14.

A transmission belt 22 is arranged between the transmission gear 13, the second belt seat 16 and the third belt seat 18, thereby facilitating the operation of driving the transmission belt 22 by the first servo motor 15.

[0026] During operation, when the welding gun 8 is started to weld the cylindrical workpiece 3 and the corresponding workpiece, by starting the first servo motor 15, the output end of the first servo motor 15 then drives the first connecting column 14 and the second belt seat 16 to rotate, so that the second belt seat 16 drives the transmission belt 22 thereon to rotate between the transmission gear 13, the second belt seat 16 and the third belt seat 18. Then, the second belt seat 16 drives the transmission gear 13 and the transmission column 11 to rotate through the transmission belt 22, so that the transmission column 11 and the first belt seat 12 drive the transmission semi-ring frame 6 and the limiting semi-circular frame 7 to rotate inside the semi-circular welding frame 5. Then, the limiting semi-circular frame 7 drives the welding gun 8 to weld the fixed cylindrical workpiece 3 and the corresponding workpiece.

When the rotated transmission semi-ring frame 6 and the limiting semi-circular frame 7 drive the welding gun 8 to rotate 360°, the welding of the cylindrical workpiece 3 and the corresponding workpiece is completed.

Moreover, its preset circumferential welding track avoids the problems of breakpoints and trajectory deviations in traditional manual welding. While improving the welding efficiency, it improves the yield rate of the welding of the cylindrical workpiece and further reduces the loss cost of the enterprise. Embodiment

[0027] As Figure 7 andFigure 8 As shown, in order to facilitate the adjustment of the tightness of the transmission belt 22 for its transmission, the positioning structure includes a fixed column 19, an adjusting block 20 and a tensioning bolt 21. The end of the second connecting column 17 far from the production frame 1 is slidably connected with the fixed column 19, and the fixed column 19 is fixedly connected with the semi-circular welding frame 5. In order to facilitate the adjustment of the position between the third belt seat 18 and the second belt seat 16, an adjusting block 20 is fixedly connected to the end of the semi-circular welding frame 5 close to the production frame 1 and corresponding to the second connecting column 17. The inner side of the adjusting block 20 is threadedly connected with the tensioning bolt 21, and the end of the tensioning bolt 21 close to the first servo motor 15 is threadedly connected with the second connecting column 17.

[0028] During work, when it is necessary to drive the welding gun 8 to rotate and weld through the transmission belt 22 before welding, by rotating the tensioning bolt 21, the tensioning bolt 21 drives the second connecting column 17 and the third belt seat 18 to move on the fixed column 19 through rotation, and then moves them to the position corresponding to the first connecting column 14, so as to facilitate the first connecting column 14 to drive the transmission belt 22 to operate through the second belt seat 16. Embodiment

[0029] As Figures 1 - 11 shown, in order to facilitate driving the semi-circular welding frame 5 and the welding gun 8 to be adjusted to a suitable welding position, the automatic adjustment assembly includes a transmission screw 23 and a second servo motor 24. The inner side of the production frame 1 is rotatably connected with the transmission screw 23, and a second servo motor 24 is fixedly connected to the inner side of the production frame 1 and at the end far from the welding column 2, so as to facilitate driving the welding column 2 to move through the first L-shaped frame 25. The output end of the second servo motor 24 is fixedly connected with the transmission screw 23.

[0030] The automatic adjustment assembly further includes a first L-shaped frame 25, a second L-shaped frame 26, a limiting column 27 and a limiting ring seat 28.

A plurality of limiting ring seats 28 are slidably connected to the circumferential side of the end of the limiting column 27 far from the welding column 2, and the limiting ring seats 28 are fixedly connected with the second L-shaped frame 26.

[0031] To facilitate the positioning of the cylindrical workpiece 3 to be welded, the supporting and fixing assembly includes a supporting outer column 29 and a supporting inner column 30. The end of the production rack 1 far from the welding column 2 is fixedly connected with the supporting outer column 29. The inner side of the supporting outer column 29 is slidably connected with the supporting inner column 30. The end of the second L-shaped frame 26 far from the transmission screw 23 is fixedly connected with the supporting inner column 30. Thus, when driving the movement of the welding column 2 through the first L-shaped frame 25, it simultaneously drives the movement of the supporting inner column 30 through the second L-shaped frame 26.

Thus, it is convenient to stably support and position the cylindrical workpiece 3 from its interior through the cooperation of multiple groups of first support frames 31 and second support frames 32.

[0033] During work, when the position of the cylindrical workpiece 3 and the external welding workpiece is determined and the cylindrical workpiece 3 is sleeved on the supporting inner column 30, by starting the second servo motor 24, the output end of the second servo motor 24 drives the transmission screw 23 to rotate. Then, under the limitation of the limiting column 27, the first L-shaped frame 25 drives the semi-circular welding frame 5 and the welding gun 8 to move towards the welding point on the cylindrical workpiece 3 through the welding column 2. The second L-shaped frame 26 drives the supporting inner column 30 to move towards the semi-circular welding frame 5 in the supporting outer column 29. While the supporting inner column 30 is moving, it drives the first support frame 31 and the second support frame 32 to rotate, making the supporting top piece 33 fit with the inner wall of the cylindrical workpiece 3, so as to support and position the cylindrical workpiece 3. By adopting the internal support method for the cylindrical part, the contact between its exterior and the workpiece is reduced. While facilitating the welding, it is also convenient for the cleaning efficiency of its exterior after welding is completed. Embodiment
