The barrel cover is limited by the limiting device 2, and the steel barrel is placed on the top of the support rollers 15 on both sides so that it is located on the right side of the welding device 14. The support rollers 15 on both sides support the steel barrel from the bottom of the steel barrel, and then the first electric push rod 12 drives the top plate 13 to move downward, and drives the side of the top plate 13 to move downward through the top plate 13. The structure set on the surface moves, so that the arc-shaped clamping plate 118 is close to the top of the steel drum, and the first screw 19 is driven to rotate by the second motor 18, and the first movable plate 110 is driven to move by the first screw 19, and the third motor 111 and the first push plate 120 are driven to move by the first movable plate 110, so that the side of the first push plate 120 is against the side of the steel drum. When the first movable plate 110 drives the first push plate 120 to move, the first push plate 120 pushes the steel drum toward the welding device 14, so that the part of the steel drum that needs to be welded is connected to the barrel cover, and then the third motor 111 drives the second screw 112 to rotate, and the trapezoidal plate 113 is driven to move toward the push rod 119 by the second screw 112, so that the side of the trapezoidal plate 113 contacts the push rods 119 on both sides thereof.When the push rod 119 rotates, it rotates at the bottom of the second movable plate 116, and the push rod 119 does not contact the bottom surface of the second movable plate 116, and the arc-shaped clamping plate 118 is rotatably connected to the L-shaped connecting frame 117, so the arc-shaped clamping plate 118 can rotate with the point connected to the L-shaped connecting frame 117 as the center.

The inner side of the arc-shaped splint 118 contacts the surface of the steel drum to limit the surface of the steel drum. The length from the fixed point of the arc-shaped splint 118 and the push rod 119 to the side of the trapezoidal plate 113, plus the thickness of the arc-shaped splint 118 itself, is less than the vertical distance between the top surface of the arc-shaped splint 118 and the bottom surface of the trapezoidal plate 113, so as to reserve enough rotation space to prevent the barrel from shaking when rotating. When the arc-shaped splint 118 contacts the steel drum, the trapezoidal plate 113 cannot be pushed, and the support roller 15 is driven to rotate by the first motor 16, and the support rollers 15 on both sides move to the same The steel drum is rotated in the direction of rotation, driving the top steel drum to rotate, and the steel drum is welded by the welding device 14.

The support rollers 15 on both sides support the steel barrel from the bottom of the steel barrel. Then the first electric push rod 12 drives the top plate 13 to move downward, and the structure set on the side of the top plate 13 is driven to move through the top plate 13, so that the arc splint 118 is close to the top of the steel barrel. The first screw 19 is driven to rotate by the second motor 18, and the first movable plate 110 is driven to move by the first screw 19. The third motor 111 and the first push plate 12 are driven by the first movable plate 110. 0 moves, so that the side of the first push plate 120 is against the side of the steel barrel. When the first movable plate 110 drives the first push plate 120 to move, the first push plate 120 pushes the steel barrel toward the welding device 14, so that the part of the steel barrel that needs to be welded is connected to the barrel cover.

When the side of the trapezoidal plate 113 contacts the push rods 119 on both sides thereof, the push rods 119 can be pushed to rotate. The push rods 119 drive the arc splint 118 to rotate around the connection part with the L-shaped connecting frame 117, so that the inner side of the arc splint 118 contacts the surface of the steel drum, limiting the surface of the steel drum. The length from the fixed point of the arc splint 118 and the push rod 119 to the side of the trapezoidal plate 113, plus the thickness of the arc splint 118 itself, is less than the vertical distance between the top surface of the arc splint 118 and the bottom surface of the trapezoidal plate 113, so as to reserve enough rotation space to prevent the barrel from shaking when it rotates. When the arc splint 118 contacts the steel drum, the trapezoidal plate 113 3 cannot be pushed, the support rollers 15 are driven to rotate by the first motor 16, and the support rollers 15 on both sides rotate in the same direction, driving the top steel drum to rotate, and the steel drum is welded by the welding device 14; when the drum cover is placed on the support rollers 15 on both sides, the first cylinder 21 pushes the movable frame 22 to move downward, and the movable frame 22 pushes the first limiting shafts 23 and the second push plates 24 on both sides to move downward.

When the push rod 119 drives the arc splint 118 to rotate, the side of the arc splint 118 pulls the bottom end of the first return spring 51 to retract. When the side of the trapezoidal plate 113 contacts the push rod 119, the bottom end of the first return spring 51 is retracted. When the rod 119 is separated, the first return spring 51 contracts, pulling the arc-shaped clamping plate 118 to rotate through the bottom end, and the arc-shaped clamping plate 118 drives the push rod 119 to reset, so that the arc-shaped clamping plate 118 can clamp again. The arc-shaped clamping plate 118 resets and rotates around the connection with the L-shaped connecting frame 117. When the arc-shaped clamping plate 118 clamps the barrel body, the surface of the arc-shaped clamping plate 118 does not contact the limit rod 52. When the arc-shaped clamping plate 118 is separated from the barrel body, the arc-shaped clamping plate 118 stops resetting and rotating until the surface contacts the limit rod 52.When the trapezoidal plate 113 moves toward the pushing rod 119, it drives the tension ropes 62 on both sides to move, and the other end of the tension rope 62 drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the turntable 63 to rotate, and the turntable 63 drives the driving shaft 64 to rotate, and the driving shaft 64 drives the moving ring 66 to slide downward on the inner side of the limiting plate 65, and drives the fixed rod 67 to move downward through the moving ring 66, and pushes the second return spring 69 inside through the fixed rod 67 to drive the sliding rod 68 to move downward, and drives the limiting frame 610 to move downward through the sliding rod 68, and drives the second limiting shaft 611 to move downward through the limiting frame 610. , so that the second limiting shaft 611 limits the surface of the stainless steel barrel.
