[0015] A steel cylinder welding frame for fire extinguisher production and a method for using the same, comprising the following steps:

[0016] Step 1: welding, setting the second half-body bottle sleeve on the outside of the centering component, then buckling the first half-body bottle with the second half-body bottle, starting the motor, the motor drives the rotating shaft to rotate, the rotating shaft drives the cross sleeve to rotate, the cross sleeve drives the cross plate to rotate, and at the same time starting the electric telescopic rod, the electric telescopic rod squeezes the cross plate, so that the cross plate drives the sliding rod to move and rotate, and the sliding rod drives the extrusion shell to move and rotate. When the extrusion shell moves, it will contact the side wall of the first half-body bottle, squeeze the first half-body bottle and the second half-body bottle, and drive the first half-body bottle and the second half-body bottle to rotate at the same time. At this time, start the welder to weld the connection between the first half-body bottle and the second half-body bottle;

[0017] Step 2: Improve the buckle effect. When the two arc-shaped clamping plates clamp the outer wall of the first half body bottle, the arc-shaped clamping plates will drive the round frame rod to slide along the outer wall of the moving frame due to the reaction force of the first half body bottle. The arc-shaped clamping plates are elastically deformed by the third spring, which can prevent the first half body bottle from being over-clamped. At the same time, the extrusion shell moves toward the cross plate, and the moving frame is limited by the cross bar and will not move, so that the moving frame drives the arc-shaped clamping plates in the clamping assembly to slide along the outer wall of the first half body bottle, pushing the outer wall of the first half body bottle, thereby improving the buckle stability of the first half body bottle and the second half body bottle;

[0018] Step three: improving the rotation stability, when the first half body bottle is squeezed by the extrusion shell, the first half body bottle drives the semicircular block to move, the semicircular block drives the sliding frame to slide along the inner wall of the working shell, the sliding plate is blocked by the working shell, and the sliding plate slides along the outer wall of the sliding frame, so that the sliding plate and the semicircular block approach each other, the sliding plate drives the second rotating rod and the semicircular block drives the first rotating rod to approach each other, and the four concave shells move away from each other due to the limitation of the concave shell, the concave shell drives the support frame to move, the support frame drives the cooling shell to move, and the four cooling shells move away from each other, so as to prop up the inner wall of the second half body bottle, so that the second half body bottle and the first half body bottle are aligned and supported;

[0019] Step 4: Auxiliary welding. The cooling shell is no longer blocked during the movement of the movable plate. Due to the setting of the cooler, the cooler cools the inside of the first half body bottle and the second half body bottle to prevent the temperature from being too high during the welding process, thereby improving the welding effect of the welder. In addition, when the first half body bottle drives the second half body bottle to move, the second half body bottle will contact the side wall of the sliding plate and be blocked by the sliding plate, thereby improving the cooling effect inside the first half body bottle and the second half body bottle.

[0020] The present invention has the following beneficial effects:

[0021] (1) In the present invention, the second half-body bottle sleeve is arranged on the outside of the centering component, and then the first half-body bottle and the second half-body bottle are buckled, and the motor is started, the motor drives the rotating shaft to rotate, the rotating shaft drives the cross sleeve to rotate, the cross sleeve drives the cross plate to rotate, and at the same time, the electric telescopic rod is started, the electric telescopic rod squeezes the cross plate, so that the cross plate drives the sliding rod to move and rotate, and the sliding rod drives the extrusion shell to move and rotate. When the extrusion shell moves, it will contact the side wall of the first half-body bottle, squeeze the first half-body bottle and the second half-body bottle, and drive the first half-body bottle and the second half-body bottle to rotate at the same time. At this time, the welding machine is started to weld the first half-body bottle and the second half-body bottle. The welding work is performed at the connection between the first half body bottle and the second half body bottle. When the extrusion shell contacts the first half body bottle, the reaction force of the first half body bottle causes the extrusion shell to move toward the cross plate, and the extrusion shell drives the sliding rod to slide along the inner wall of the cross plate, and the cross plate drives the rotating plate to move. The rotating plate is limited by the cross bar, and the rotating plate drives the moving frame to move along the outer wall of the cross bar. The moving frame drives the round frame rod to move, and the round frame rod drives the arc clamping plate to move. The two arc clamping plates approach each other, thereby clamping the outer wall of the first half body bottle, improving the rotation stability of the first half body bottle and the second half body bottle, and laterally improving the welding effect of the welder on the connection between the first half body bottle and the second half body bottle.

[0022] (2) According to the present invention, when the two arc-shaped clamping plates clamp the outer wall of the first half body bottle, the arc-shaped clamping plates will drive the round frame rod to slide along the outer wall of the moving frame due to the reaction force of the first half body bottle, and the elastic deformation of the third spring can prevent the first half body bottle from being over-clamped. At the same time, the extrusion shell moves toward the cross plate, and the moving frame will not move due to the limitation of the cross bar, so that the moving frame drives the arc-shaped clamping plates in the clamping assembly to slide along the outer wall of the first half body bottle, pushing the outer wall of the first half body bottle, thereby improving the buckle stability of the first half body bottle and the second half body bottle, preventing the first half body bottle and the second half body bottle from having a gap at the connection during the rotation process, and indirectly improving the welding effect of the welder.

[0023] (3) According to the present invention, when the first half body of the bottle is squeezed by the extrusion shell, the first half body of the bottle drives the semicircular block to move, and the semicircular block drives the sliding frame to slide along the inner wall of the working shell. The sliding plate is blocked by the working shell, and the sliding plate slides along the outer wall of the sliding frame, so that the sliding plate and the semicircular block approach each other, and the sliding plate drives the second rotating rod and the semicircular block drives the first rotating rod to approach each other. The four concave shells are limited by the concave shell, and the four concave shells move away from each other. The concave shell drives the support frame to move, and the support frame drives the cooling shell to move, and the four cooling shells move away from each other, so as to prop up the inner wall of the second half body of the bottle, so that the second half body of the bottle and the first half body of the bottle are aligned and propped up, so as to prevent the deviation during the rotation process and improve the rotation stability of the second half body of the bottle and the first half body of the bottle.

[0024] (4) According to the present invention, when the cooling shell moves, it is subjected to the reaction force of the second half body bottle, and the cooling shell drives the support frame to slide along the inner wall of the concave shell. The cooling shell and the concave shell approach each other, so that the rotating bar rotates slightly along the concave shell. Due to the limitation of the cooling shell, the rotating bar drives the moving plate to slide along the inner wall of the cooling shell, and the moving plate drives the pushing block to move. During the movement of the pushing block, the pushing block will contact the inner wall of the second half body bottle, so that the second half body bottle moves toward the first half body bottle, further improving the snapping effect of the first half body bottle and the second half body bottle, and the cooling shell is no longer blocked during the movement of the moving plate. Due to the setting of the cooler, the cooler cools the interior of the first half body bottle and the second half body bottle to prevent the temperature from being too high during the welding process, thereby improving the welding effect of the welder. During the movement of the second half body bottle driven by the first half body bottle, the second half body bottle will contact the side wall of the sliding plate and be blocked by the sliding plate, thereby improving the cooling effect of the interior of the first half body bottle and the second half body bottle.

[0052] Step 3: Improve the rotation stability. When the first half-body bottle 574 is squeezed by the extrusion shell 555, the first half-body bottle 574 drives the semicircular block 572 to move, and the semicircular block 572 drives the sliding frame 571 to slide along the inner wall of the working shell 2. The sliding plate 573 is blocked by the working shell 2, and the sliding plate 573 slides along the outer wall of the sliding frame 571, so that the sliding plate 573 and the semicircular block 572 are close to each other. The sliding plate 573 drives the second rotating rod 577 and the semicircular block 572 drives the first rotating rod 576 to approach each other. The four concave shells 579 are limited by the concave shell 579, and the four concave shells 579 move away from each other. The concave shell 579 drives the support frame 581 to move, and the support frame 581 drives the cooling shell 582 to move, and the four cooling shells 582 move away from each other, so as to support the inner wall of the second half-body bottle 575, so that the second half-body bottle 575 and the first half-body bottle 574 are aligned and supported;

[0053] Step 4: Auxiliary welding. During the movement of the movable plate 584, the cooling shell 582 is no longer blocked. Due to the setting of the cooler 583, the cooler 583 cools down the inside of the first half body bottle 574 and the second half body bottle 575 to prevent the temperature from being too high during the welding process, thereby improving the welding effect of the welder 4. In addition, during the movement of the second half body bottle 575 driven by the first half body bottle 574, the second half body bottle 575 will contact the side wall of the sliding plate 573 and be blocked by the sliding plate 573, thereby improving the cooling effect inside the first half body bottle 574 and the second half body bottle 575.

[0054] When in use, the second half body bottle 575 is sleeved on the outside of the centering component 57, and then the first half body bottle 574 and the second half body bottle 575 are buckled, and the motor 3 is started. The motor 3 drives the rotating shaft 51 to rotate, and the rotating shaft 51 drives the cross sleeve 52 to rotate, and the cross sleeve 52 drives the cross plate 53 to rotate. At the same time, the electric telescopic rod 54 is started, and the electric telescopic rod 54 squeezes the cross plate 53, so that the cross plate 53 drives the sliding rod 553 to move and rotate, and the sliding rod 553 drives the extrusion shell 555 to move and rotate. When the extrusion shell 555 moves, it will contact the side wall of the first half body bottle 574, squeeze the first half body bottle 574 and the second half body bottle 575, and drive the first half body bottle 574 and the second half body bottle 575 to rotate. At this time, the welder 4 is started to weld the connection between the first half body bottle 574 and the second half body bottle 575. During welding, when the extrusion shell 555 contacts the first half body bottle 574, the reaction force of the first half body bottle 574 is applied, and the first half body bottle 574 causes the extrusion shell 555 to move toward the cross plate 53, and the extrusion shell 555 drives the sliding rod 553 to slide along the inner wall of the cross plate 53, and the cross plate 53 drives the rotating plate 562 to move. Limited by the cross bar 561, the rotating plate 562 drives the moving frame 563 to move along the outer wall of the cross bar 561, and the moving frame 563 drives the round frame rod 564 to move, and the round frame rod 564 drives the arc clamping plate 566 to move, and the two arc clamping plates 566 approach each other, thereby clamping the outer wall of the first half body bottle 574, improving the rotation stability of the first half body bottle 574 and the second half body bottle 575, and laterally improving the welding effect of the welder 4 on the connection between the first half body bottle 574 and the second half body bottle 575.

[0055] When the two arc-shaped clamping plates 566 clamp the outer wall of the first half body bottle 574, the arc-shaped clamping plates 566 will drive the round frame rod 564 to slide along the outer wall of the moving frame 563 due to the reaction force of the first half body bottle 574. Under the elastic deformation of the third spring 565, it can prevent the first half body bottle 574 from being excessively clamped. At the same time, the extrusion shell 555 moves toward the cross plate 53, and the moving frame 563 is limited by the cross bar 561 and will not move, so that the moving frame 563 drives the arc-shaped clamping plates 566 in the clamping assembly 56 to slide along the outer wall of the first half body bottle 574, pushing the outer wall of the first half body bottle 574, thereby improving the buckle stability of the first half body bottle 574 and the second half body bottle 575, preventing the first half body bottle 574 and the second half body bottle 575 from having a gap at the connection during the rotation process, and the side surface improves the welding effect of the welder 4.

[0056] When the first half-body bottle 574 is squeezed by the squeezing shell 555, the first half-body bottle 574 drives the semicircular block 572 to move, and the semicircular block 572 drives the sliding frame 571 to slide along the inner wall of the working shell 2. The sliding plate 573 is blocked by the working shell 2, and the sliding plate 573 slides along the outer wall of the sliding frame 571, so that the sliding plate 573 and the semicircular block 572 are close to each other, and the sliding plate 573 drives the second rotating rod 577 and the semicircular block 572 drives the first rotating rod 576 to move relative to each other. The four concave shells 579 move away from each other and are limited by the concave shell 579. The concave shell 579 drives the support frame 581 to move, and the support frame 581 drives the cooling shell 582 to move. The four cooling shells 582 move away from each other, thereby propping up the inner wall of the second half body bottle 575, so that the second half body bottle 575 and the first half body bottle 574 are aligned and propped up to prevent deviation during rotation, thereby improving the rotation stability of the second half body bottle 575 and the first half body bottle 574.

[0057] When the cooling shell 582 moves, it is subjected to the reaction force of the second half-body bottle 575, and the cooling shell 582 drives the support frame 581 to slide along the inner wall of the concave shell 579, and the cooling shell 582 and the concave shell 579 approach each other, so that the rotating bar 585 rotates slightly along the concave shell 579, and is limited by the cooling shell 582. The rotating bar 585 drives the moving plate 584 to slide along the inner wall of the cooling shell 582, and the moving plate 584 drives the pushing block 586 to move. During the movement of the pushing block 586, it contacts the inner wall of the second half-body bottle 575, so that the second half-body bottle 575 moves toward the first half-body bottle 574, and further The buckling effect of the first half body bottle 574 and the second half body bottle 575 is further improved, and the cooling shell 582 is no longer blocked during the movement of the movable plate 584. Due to the setting of the cooler 583, the cooler 583 cools the inside of the first half body bottle 574 and the second half body bottle 575 to prevent the temperature from being too high during the welding process, thereby improving the welding effect of the welder 4. In the process of the first half body bottle 574 driving the second half body bottle 575 to move, the second half body bottle 575 will contact the side wall of the sliding plate 573 and be blocked by the sliding plate 573, thereby improving the cooling effect of the first half body bottle 574 and the second half body bottle 575.

At this time, the welding device (4) is started to weld the connection between the first half body bottle (574) and the second half body bottle (575); Step 2: improving the snap-fit ​​effect. When the two arc-shaped clamping plates (566) clamp the outer wall of the first half-body bottle (574), the arc-shaped clamping plates (566) are subjected to the reaction force of the first half-body bottle (574), and drive the round frame rod (564) to slide along the outer wall of the moving frame (563).
