During the process, the motor can be turned on to make the transmission support roller drive the welded tank body to rotate, so that the welded tank body can rotate synchronously with the conical head to adjust the welding position. At the same time, the welding detection camera can be used to observe the welding condition of the connection between the conical head and the welded tank body. When a defect occurs, the defect can be aligned with the welding head by controlling the direction of the motor output end to perform the repair welding operation.

[0024] (4) According to the present invention, after the conical end cap is sleeved on the movable arc clamp and the welded tank body is placed on the transmission support roller, the electric push rod can be controlled to retract its output end, so that the movable arc clamp can clamp the conical end cap and at the same time drive the first positioning wheel and the second positioning wheel to press on the welded tank body, thereby positioning the welded tank body and preventing the welded tank body from being offset during the welding process.

While welding, turn on the motor 901 to make the conical head 7 and the welded tank body 11 rotate synchronously to change the welding position. At the same time, the welding detection camera 3 can be used to observe the welding condition of the connection between the conical head 7 and the welded tank body 11.

[0041] S6. During the welding process, by controlling the reciprocating movement of the output end of the multi-stage electric push rod 801, the slag removal steel brush 2 1303 can be driven to brush the weld of the conical head 7 to brush off the welding slag at the weld. When the motor 901 is turned on, the L-shaped threaded plate 1301 can drive the slag removal steel brush 1 1302 to reciprocate and brush the welding between the conical head 7 and the welding tank body 11 to brush off the welding slag at the welding place between the conical head 7 and the welding tank body 11, thereby improving the welding quality.

[0042] The working principle is: when welding the conical head 7, first adjust the angle of the movable arc clamp 603, refer to Figure 3When adjusting, the electric push rod 609 is turned on, and the output end of the electric push rod 609 will drive the T-shaped slide bar 608 to slide on the inner wall of the base 1. The sliding T-shaped slide bar 608 will drive the push plate 607 to move, so that the push plate 607 drives the linkage rod 606 to slide on the inner wall of the rotating shaft 601. When the linkage rod 606 slides, it will push the connecting plate 605 to move. When the connecting plate 605 moves, it will drive one end of the connecting rod 604 to rotate and move, so that the other end of the connecting rod 604 rotates on one side of the movable arc clamp 603, and at the same time, it will pull the movable arc clamp 603 to rotate on the rotating shaft 601, so that the angles of multiple movable arc clamps 603 can be adjusted at the same time, so that the movable arc clamps 603 can keep the water level. The conical head 7 is in a flat state, at this time, the conical head 7 can be put on the movable arc clamp 603, so that the outer surface of the conical head 7 is fitted with the arc clamping plate 602. At this time, the electric push rod 609 is controlled to move its output end in the opposite direction, so that the movable arc clamp 603 is flipped and reset, and the reset movable arc clamp 603 will fit with the inner wall of the conical head 7, so that the movable arc clamp 603 and the arc clamping plate 602 clamp the conical head 7 to position the conical head 7. By arranging rubber pads on the movable arc clamp 603 and the arc clamping plate 602, the clamping stability can be improved. Then, the reciprocating screw rod 902 can be driven to rotate by turning on the motor 901, and the rotating reciprocating screw rod 902 can drive the gear 9 03 rotates, so that gear one 903 drives the rotating shaft 601 and the linkage rod 606 to rotate by meshing with gear two 904, and at the same time, the rotating rotating shaft 601 drives the arc clamping plate 602 and the movable arc clamp 603 to perform circular motion, thereby driving the clamped conical head 7 to rotate, so that the position of the weld of the conical head 7 can be adjusted, so that the weld of the conical head 7 is located below the welding head 4. At this time, the welding gun 2 can be turned on to use the welding head 4 to weld the weld of the conical head 7. During the welding process, the multi-stage electric push rod 801 can be turned on, and the output end of the multi-stage electric push rod 801 can drive the movable frame 802 to move, and the movable frame 802 can drive the two sides when moving. The horizontal slider 807 slides in the two horizontal slide grooves 806 respectively, thereby limiting the moving direction of the movable frame 802. The continuously moving movable frame 802 will drive the welding gun 2 to move, and during the movement of the welding gun 2, the guide bevel blocks 805 on both sides will be driven to slide in the corresponding bevel grooves 804 respectively. At the same time, the welding gun 2 will be affected by the bevel grooves 804 and move vertically on the movable frame 802, so that the welding head 4 on the welding gun 2 can move and retract along the weld of the conical head 7. A welding inspection camera 3 is set to observe the welding condition of the conical head 7. If there is a defect at the welding place, the multi-stage electric push rod 801 can be used to control the welding head 4 to move to the defect for repair welding.

[0043] When it is necessary to weld the conical head 7 and the welding tank body 11, the welded conical head 7 can be placed on the movable arc clamp 603, and the welding tank body 11 can be placed on two transmission support rollers 1003. At this time, the electric push rod 609 is also turned on to move the T-shaped slide bar 608 to clamp the conical head 7. At the same time, the moving T-shaped slide bar 608 can drive the L-shaped extrusion plate 1201 to move, and the L-shaped extrusion plate 1201 will drive the movable rod 1202 to move, and the movable rod 1202 will drive the positioning wheel 1205 on the roller frame 1204 to contact one side of the welding tank body 11, and the auxiliary spring 1206 can be compressed and adapted according to the movement degree of the L-shaped extrusion plate 1201, so that the positioning wheel 1205 can move the welding tank body 11. The tank body 11 is pushed toward the conical head 7 to make it fully contact with the conical head 7. At the same time, the continuously moving L-shaped extrusion plate 1201 can drive its inclined surface to be extruded on the inclined surface of the inclined surface resistance block 1209, so that the inclined surface resistance block 1209 is extruded and drives the movable rod 1207 to slide and descend on the support frame 5. The descending movable rod 1207 will drive the inclined surface resistance block 1209 to descend and stretch the tension spring 1212. The continuously descending inclined surface resistance block 1209 will drive the positioning wheel 1211 on the roller frame 1210 to press on the welding tank body 11, which is used to limit the position of the welding tank body 11 and prevent it from deviating during the welding process. At this time, the multi-stage electric push rod 801 can be used to adjust the position of the welding head 4 to make it aligned with the conical head 7 and the welding tank body. 11 corresponds to the connection point, and then the conical head 7 and the welding tank body 11 can be welded. While welding, the motor 901 is turned on. Under the action of the motor 901, the reciprocating screw rod 902 and the conical head 7 can be rotated. At the same time, the rotating reciprocating screw rod 902 will drive the transmission wheel 2 1006 to rotate. While the transmission wheel 2 1006 rotates, it can drive the two transmission wheels 1 1004 to rotate at the same time through the transmission cooperation with the transmission belt 1005, so that the transmission wheel 1 1004 drives the connecting shaft 1002 to rotate, and the connecting shaft 1002 drives the transmission support roller 1003 to rotate. The transmission support roller 1003 can drive the welding tank body 11 above to rotate, so that the welding tank body 11 and the conical head 7 can be rotated and adjusted synchronously to change their welding. The position of the welding seam can be detected by the welding inspection camera 3. The welding point position of the welding tank body 11 and the conical head 7 can be adjusted by controlling the output end of the motor 901 to rotate forward and reverse, so that the welding head 4 can perform the repair welding operation. After the welding is completed, the motor 901 can be turned off, and the output end of the electric push rod 609 can be controlled to drive the T-shaped slide bar 608 to reset, so that the movable arc clamp 603 is separated from the clamping of the conical head 7, and the T-shaped slide bar 608 will drive the L-shaped extrusion plate 1201 to reset, so that the positioning wheel 1205 is separated from the contact with the welding tank body 11, and the L-shaped extrusion plate 1201 will be separated from the extrusion of the inclined surface block 1209. At this time, the tension spring 1212 in the stretched state will pull the inclined surface block 1209 to rise and reset.Then the positioning wheel 2 1211 is driven to disengage from the squeeze on the welding tank body 11, thereby releasing the restriction on the welding tank body 11 and the conical head 7, so that it can be taken out and replaced for subsequent welding operations.

[0044] By controlling the multi-stage electric push rod 801 to drive the welding gun 2 to move back and forth, the welding gun 2 can drive the slag removal steel brush 2 1303 to brush back and forth at the weld of the conical head 7, so as to brush off the welding slag of the weld of the conical head 7. When the conical head 7 and the welding tank body 11 are welded, when the motor 901 is turned on, the rotating reciprocating screw rod 902 can drive the L-shaped threaded plate 1301 to move back and forth through the thread cooperation with the L-shaped threaded plate 1301. The reciprocating L-shaped threaded plate 1301 will slide in the limiting slide groove 1304, thereby limiting the moving direction of the L-shaped threaded plate 1301. The continuously moving L-shaped threaded plate 1301 will drive the slag removal steel brush 1 1302 to brush the welding point between the conical head 7 and the welding tank body 11 to brush off the welding slag. By brushing off the welding slag, the welding quality is improved.
