[0024] Embodiment 1

[0025] The utility model provides a circular fuel tank rotary welding equipment, can realize automatic rotary welding procedure to circular oil tank. Figure 1 As shown, the equipment is symmetrically provided with end cover positioning rotary mechanism on both sides, and is provided with barrel body rotary mechanism 10 at the bottom.

[0026] The end cover positioning rotary mechanism comprises a servo system 2, a main shaft 1 drivingly connected with the servo system 2, a rotary plate 3 provided at one end of the main shaft 1 close to the workpiece 9, and an end cover positioning structure fixed on the rotary plate 3. The end cover positioning structure comprises a transverse positioning cylinder 4 provided in the axial direction of the main shaft 1, and a vertical positioning cylinder 6 provided in the radial direction of the main shaft 1 and fixed at the output end of the transverse positioning cylinder 4. The output end of the vertical positioning cylinder 6 is embedded with an end cover positioning block 5 matched with the end cover of the workpiece 9 for mounting and fixing the end cover.

[0027] As shown in Figure 2 , 3 The barrel body rotary mechanism 10 comprises a main frame 22, a driving wheel shaft 16 and a driven wheel shaft 15 are provided in parallel in the axial direction of the workpiece 9 in the main frame 22, a plurality of driving wheels 17 with a netted surface are provided on the driving wheel shaft 16, and a plurality of driven wheels 18 with a smooth surface are provided on the driven wheel shaft 15.

[0028] One side of the driving wheel shaft 16 is connected with the output end of a servo motor 11 through a shaft coupling 12 and is rotatably connected with the main frame 22 through a main fixing block 13; the other side of the driving wheel shaft 16 is rotatably connected with the main frame 22 through a bearing 19. The main frame 22 is provided with adjustable guide rails 20 on both sides in the radial direction of the workpiece 9, a secondary fixing block 21 is movably arranged in the adjustable guide rails 20, and the driven wheel shaft 15 is fixed to the main frame 22 through the secondary fixing block 21.

[0029] The outer sides of the left and right two main shafts 1 are provided with hand wheels 7 for manually adjusting the position of the rotary plate 3. Since the temperature during welding can reach more than 600 degrees, the workpiece 9 and the equipment parts are easily deformed due to heat, especially the vertical positioning cylinders 6 on the left and right sides of the end cover, which are not easy to slide and feed after heat deformation. Therefore, heat insulation plates 8 are added on the side of the two vertical positioning cylinders 6 close to the welding gun.

During the welding process, the position of the welding gun remains unchanged, the main shaft 1 is driven by the rotating servo system 2 on both sides to rotate, the rotating plate 3 is driven to rotate by the main shaft 1, and then the end cover side of the workpiece 9 is driven to rotate by the end cover positioning mechanism installed on the rotating plate 3. The rotating mechanism 10 located below the barrel body of the workpiece 9 is driven by the servo motor 11 through the speed regulator 14 and the shaft coupling 12 to drive the driving wheels 17 and the driven wheels 18 located below the barrel body of the workpiece 9 on both sides to rotate, and then the barrel body is driven to rotate synchronously.
