The high-precision welding of the tank plays a vital role in the performance and safety of the transformer. The tank is usually welded by multiple sections of circular pipes to flexibly adjust the volume of the tank to meet the needs of different transformers. The structure welded by multiple sections of circular pipes can ensure the strength and stability of the oil conservator.

A waist-shaped groove is formed at the other end of the driving rod 232. Guide posts 234 that slide through the corresponding waist-shaped grooves are installed on the rectangular blocks 231. An actuator for driving the two U-shaped plates 230 to move towards each other is arranged on the support plate 11.

[0039] As Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, the driving member 223 includes a spline sleeve 2230. The spline sleeve 2230 is rotatably installed on the support plate 20.

The longitudinal sections of the two U-shaped plates 230 are respectively threadedly connected to the two threaded sections of the bidirectional screw 235, and the bidirectional screw 235 also movably penetrates through the two support plates 20.

[0041] During specific operation, the external clamping device inserts the circular tube into the through hole of the support plate 20, and then the external No. 1 motor installed on the support plate 11 drives the spline shaft 2232 to rotate, and the spline shaft 2232 drives the corresponding No. 1 spur gear 2231 to rotate through the spline sleeve 2230, and the No. 1 spur gear 2231 drives the corresponding external gear ring 220 to rotate. Under the cooperation of the T-bar 2240 and the guide groove 2242, the rotation of the T-tube 4 is restricted, so the external gear ring 220 The rotation will first push the limit plate 222 to move toward the circular tube through the cooperation of the column 2235 and the inclined groove 2234, so that the limit plate 222 squeezes the circular tube. At the same time, the limit plate 222 will drive the T-shaped rod 2240 to move synchronously along the radial direction of the T-shaped tube 4, and the T-shaped rod 2240 slides in the arc waist groove on the outer gear ring 220 to ensure that the T-shaped rod 2240 can move normally along the radial direction of the T-shaped tube 4.

At this time, the external No. 1 motor stops rotating, and then the external No. 2 motor installed on the supporting plate 11 drives the bidirectional screw 235 to rotate, and the bidirectional screw 235 drives the two U-shaped plates 230 to approach each other, and the U-shaped plate 230 drives the driving rod 232 to rotate through the rectangular block 231 and the guide column 234, and the driving rod 232 drives the extrusion block 233 to extrude the circular tube. At this time, the driving rod 232 cannot rotate further, and the bidirectional screw 235 continues to rotate. Drive the corresponding support plates 20 to approach each other through the driving rod 232, thereby making the circular tubes on the two support plates 20 relative to each other. At the same time, the extrusion block 233 extrudes the circular tube and limits the circular tube, and the fixing part 22 extrudes the circular tube to fix it, so as to ensure the stability of the circular tube during the movement and docking process in a double fixing manner.

[0042] like Figure 1 , Figure 2 and Figure 6 As shown, the welding portion 21 includes a slide plate 210, and the opposite surfaces of the support plate 20 are slidably installed with the slide plate 210 up and down, and the upper end surface of the slide plate 210 is symmetrically installed with a shaft column 211, and a rectangular plate 212 is slidably installed on the shaft column 211. A waist groove 213 is provided at a position corresponding to the shaft column 211 on the rectangular plate 212, and a connecting plate 214 is slidably installed at the upper and lower end surfaces of the rectangular plate 212 and the corresponding positions of the slide plate 210, and the connecting plate 214 is fixedly connected to the corresponding two shaft columns 211, and a T-shaped sleeve 215 is provided in the middle of the rectangular plate 212, and the vertical end of the T-shaped sleeve 215 slides through the rectangular plate 212, and a tension spring 216 is provided between the horizontal end of the T-shaped sleeve 215 and the rectangular plate 212, and a welding head 217 is installed in the T-shaped sleeve 215, and an adjusting member 218 for adjusting the position of the welding head 217 is provided on the right side of the rectangular plate 212.

[0043] like Figure 1 , Figure 2 and Figure 8 As shown, the adjusting member 218 includes a stepper motor 2180, and the stepper motor 2180 is fixedly installed on the slide plate 210 on the right side.

A rope 2185 is wound around the winding wheel 2181, and one end of the rope 2185 passes around the guide wheel 2184 and then passes through the rectangular hole to be connected with the stop plate 2183.

[0044] like Figure 6 As shown, a support plate 2150 is fixedly installed at the lower part of the T-shaped sleeve 215, and a guide rod sliding through the rectangular plate 212 is installed on the upper end surface of the support plate 2150, and an axle seat is symmetrically installed in the front and rear ends of the lower end surface of the support plate 2150, and a rotating shaft is rotatably installed at the lower part of the axle seat, and rollers 2151 that fit the outer wall of the circular tube are installed at both left and right ends of the rotating shaft.

On the other hand, it is used to reduce the obstruction to the circumferential rotation of the circular tube and ensure the smoothness and stability of the rotational welding of the circular tube.

[0046] During operation, the external electric telescopic rod installed on the support plate 20 pulls the slide plate 210 to move downward, and the slide plate 210 drives the rectangular plate 212 to move downward through the shaft column 211 and the connecting plate 214, and the rectangular plate 212 drives the T-shaped sleeve 215, the welding head 217 and the roller 2151 to move toward the circular tube until the roller 2151 fits with the circular tube, and then the stepper motor 2180 drives the winding wheel 2181 to rotate, and the winding wheel 2181 winds up the rope 2185, and the rope 2185 pulls the resistance The baffle plate 2183 rotates downward from a horizontal state to a vertical state.

[0047] Afterwards, the external electric telescopic rod pulls the rectangular plate 212 further downward to stretch the tension spring 216, increase the force on the T-shaped sleeve 215, and improve the stability of the welding head 217. Then the external No. 1 motor continues to drive the spline shaft 2232 to rotate, and the spline shaft 2232 drives the outer gear ring 220 to rotate through the No. 1 spur gear 2231, so as to drive the circular tube to rotate while maintaining the extrusion and fixation of the circular tube, thereby ensuring the integrity of the welding. Afterwards, the left end of the welded circular tube is pushed through the through hole on the fixing plate 30 until it contacts the blocking plate 12, thereby releasing the fixation of the circular tube. Then the electric slider (not shown in the figure) drives the supporting plate 11 and the fixing part 22 to move to the right, and the support plate 20 on the right side is separated from the circular tube, so that the external clamping device clamps the circular tube to be welded through the through hole of the support plate 20 on the right side. Hole, then repeat the above operation, fix the circular tube and dock it with the welded circular tube, then the external servo motor installed on the fixing plate 30 drives the corresponding fixing part 22 through the No. 2 spur gear 2233 to clamp, fix and support the left end of the leftmost circular tube after welding, so as to ensure the stability of the tank body after welding, then the welding part 21 adjusts the welding position, and then the external No. 2 motor and the external servo motor synchronously drive the circular tube to rotate for welding, so as to weld the tank body step by step to the required size, release the fixation of the circular tube, clamp and fix the welded tank body by the external clamping device, and then the electric slider drives the two support plates 20 to completely detach from the welded tank body, and then the external clamping device removes the welded tank body, and then the circular tubes to be welded are sent in one by one for welding.
