When the sheet metal is placed on the workbench, the L-shaped block is driven to rotate under the gravity of the sheet metal, so that the arc-shaped spring 2 generates elastic force, thereby driving the roller 2 to move and press the sheet metal. When the L-shaped block rotates, it presses the small rack downward, so that the spring 2 is compressed and generates elastic force, thereby causing the small rack to move downward in the slide groove 1 and drive the rotating shaft 2 to rotate through the pinion, thereby driving the wire wheel to rotate and retracting the rope, thereby The slide plates are pulled closer to each other by ropes to fix the sheet metal. When the slide plates move, they squeeze spring 1 to generate elastic force. When the clamping plate fixes the sheet metal, the spring telescopic rod can prevent the sheet metal from being damaged during clamping.

When the two silicone When the rubber plates are in contact, the piston cylinder on the right side pushes the silicone plate to move through spring three, and the silicone plate drives the arc plate to move through the protruding block on the telescopic rod, thereby squeezing spring four to generate elastic force, so that the arc plate moves to open the middle air outlet pipe, thereby discharging air from the middle air outlet pipe. Because the edge of the silicone plate is softer, when the arc plate moves to the far left, the silicone plate can pass through. Under the action of the elastic force of spring four, the arc plate is reset to block the middle air outlet pipe, thereby discharging air from the left air outlet pipe. When the piston cylinder moves to the left, the air is discharged in this operating mode, which increases the pressure of the air discharge and improves the cleaning effect.

[0014] The present invention has the following beneficial effects: In order to solve the problem that the welding position of the plate is offset when the welding machine is moving, the present invention is provided with a moving mechanism and a clamping assembly inside the equipment. Before use, the gap between the plate and the welding machine is in a horizontal state, and then the motor is started, and the motor drives the height of the L-shaped bracket through the threaded rod. When the L-shaped bracket moves downward, the T-shaped slider moves to the left under the elastic force of the compression spring to prevent the belt from being too long. The L-shaped bracket drives the welding machine to move through the O-shaped plate, so that the welding machine contacts the sheet metal for welding, and then the electric telescopic rod is started, and the electric telescopic rod pushes the O-shaped plate to move to the right to drive the large rack. The strip drives the rotating shaft to rotate clockwise through the large gear, thereby pulling the belt to the right through the pulley, making the left side of the belt shorter and the right side longer, so that the belt drives the rectangular slide and the workbench to move to the left through the arc-shaped fixed block, so that the workbench and the welding machine move in opposite directions; when the electric telescopic rod pulls the O-shaped plate to drive the large rack to move to the left, the large rack drives the rotating shaft to rotate counterclockwise through the large gear, thereby moving the workbench to the right. Through the above operation mode, the moving distance of the sheet metal is reduced, the welding time is shortened, the position displacement of the sheet metal during the movement is prevented, and the welding efficiency is improved.

[0015] The present invention utilizes the gravity of the sheet metal. Under the gravity of the sheet metal, the L-shaped block is driven to rotate so that the arc spring 2 generates elastic force, thereby driving the roller 2 to move and press the sheet metal. When the L-shaped block rotates, it presses the small rack downward, so that the spring 2 is compressed and generates elastic force, so that the small rack moves downward in the slide groove 1 and drives the rotating shaft 2 to rotate through the small gear, thereby driving the wire wheel to rotate and retract the rope, thereby pulling the slide plates closer to each other through the rope, thereby fixing the sheet metal. When the slide plate moves, it squeezes the spring 1 to generate elastic force. When the clamping plate fixes the sheet metal, Under the action of the spring telescopic rod, damage to the sheet metal is prevented during clamping. The fixed block moves downward and drives roller one to move through the H-shaped bracket. When roller one squeezes the sheet metal, roller one rotates through the H-shaped bracket with the fixed block as a fulcrum, thereby flattening the interface between the two sheet metals. When the welding is completed and the sheet metal is taken out, the device is reset under the action of the elastic force of spring one, spring two and arc spring two. Through the above operation mode, the bulge when the sheet metal is connected is reduced, the position of the sheet metal is prevented from being offset during welding, and the quality of welding is improved.

[0016] The present invention utilizes the force of the movement of the arc-shaped fixing block. When the arc-shaped fixing block moves to the left, it drives the piston cylinder to move to the left. The piston cylinder stretches the right piston rod to keep the position of the right piston rod unchanged, thereby exhausting the air in the piston cylinder through the air outlet pipe through the silicone plate on the left piston rod, and blowing off the welding slag on the sheet metal; when the piston cylinder moves to the right, under the action of the right piston rod, the air inside the piston cylinder is pressurized and discharged from the air outlet pipe, and the left piston rod will be stretched to keep the position of the left piston rod unchanged. Under the action of the air exhaust force, the welding slag on the sheet metal is cleaned, so as to prevent cracks from appearing at the welding interface and improve the welding quality.

[0017] The present invention utilizes the force of the piston cylinder moving. When the piston cylinder moves to the right, the piston cylinder is separated by the silicone plate. Therefore, when the piston cylinder moves to the right, the air in the piston cylinder is discharged through the piston rod on the right, and under the action of the silicone plate, the air in the piston cylinder is discharged from an air outlet pipe to increase the pressure of air discharge. When the two silicone plates are in contact, the piston cylinder on the right side pushes the silicone plate to move through the spring three, and the silicone plate drives the arc plate to move through the protruding block on the telescopic rod, thereby squeezing the spring four to generate elastic force, so that the arc plate moves to open the middle air outlet pipe, thereby discharging air from the middle air outlet pipe. Because the edge of the silicone plate is soft, the silicone plate can pass through when the arc plate moves to the leftmost side. Under the action of the elastic force of the spring four, the arc plate is reset to block the middle air outlet pipe, thereby discharging air from the left air outlet pipe. When the piston cylinder moves to the left, the air is discharged in this operation mode, the pressure of air discharge is increased, and the cleaning effect is improved.

[0032] A specific application of this embodiment is as follows: when in use, two sheet metals to be welded together are placed on the workbench 12, and then the position of the welding machine 19 is adjusted by the fixing block 18, and the motor 14 is started. The motor 14 drives the height of the L-shaped bracket 16 through the threaded rod 15. When the L-shaped bracket 16 moves downward, the T-shaped slider 24 moves to the left under the elastic force of the compression spring 25 to prevent the belt 28 from being too long. The L-shaped bracket 16 drives the welding machine 19 to move through the O-shaped plate 17, so that the welding machine 19 contacts the sheet metal for welding, and then the electric telescopic rod 211 is started. The electric telescopic rod 211 pushes the O-shaped plate 17 to move to the right and drives the large rack 210. The large rack 210 moves to the right through the large rack 210. The wheel 29 drives the rotating shaft 26 to rotate clockwise, thereby pulling the belt 28 to move to the right through the pulley 27, making the left side of the belt 28 shorter and the right side longer, so that the belt 28 drives the rectangular slide 21 and the workbench 12 to move to the left through the arc-shaped fixed block 22, so that the workbench 12 and the welding machine 19 move in opposite directions; when the electric telescopic rod 211 pulls the O-shaped plate 17 to drive the large rack 210 to move to the left, the large rack 210 drives the rotating shaft 26 to rotate counterclockwise through the large gear 29, so that the workbench 12 moves to the right. Through the above operation mode, the moving distance of the sheet metal is reduced, the welding time is shortened, the position displacement of the sheet metal during the movement is prevented, and the welding efficiency is improved.

[0033] When the workbench 12 moves, the position of the sheet metal block may change, causing the interface of the two sheet metals to deviate. When the sheet metal is placed on the workbench 12, the L-shaped block 34 is driven to rotate under the gravity of the sheet metal, so that the arc spring 2 36 generates elastic force, thereby driving the roller 2 35 to move and press the sheet metal. When the L-shaped block 34 rotates, it presses the small rack 317 downward, so that the spring 2 318 is compressed to generate elastic force, so that the small rack 317 moves downward in the slide groove 1 316, and drives the rotating shaft 2 312 to rotate through the small gear 315, thereby driving the wire wheel 313 to rotate, and the rope 314 is retracted, so that the slide plate 38 is pulled closer to each other through the rope 314, so that the sheet metal is fixed. When the slide plate 38 moves, the spring 1 311 The extrusion generates elastic force. When the clamping plate 310 fixes the sheet metal, under the action of the spring telescopic rod 39, the sheet metal is prevented from being damaged during clamping. When the fixed block 18 moves downward, it drives the roller 1 32 to move through the H-shaped bracket 31. When the roller 1 32 extrudes the sheet metal, the roller 1 32 rotates with the fixed block 18 as the fulcrum through the H-shaped bracket 31, thereby flattening the interface between the two sheet metals. When the welding is completed and the sheet metal is taken out, the device is reset under the action of the elastic force of the spring 1 311, the spring 2 318 and the arc spring 2 36 to prevent the sheet metal from shifting during welding. Through the above operation mode, the bulge when the sheet metal is connected is reduced, the sheet metal position is prevented from shifting during welding, and the welding quality is improved.

[0034] During welding, welding slag may remain on the sheet metal, which may affect the quality of welding. When the arc-shaped fixed block 22 moves to the left, it drives the piston cylinder 41 to move to the left, and the piston cylinder 41 stretches the right piston rod 44 to keep the position of the right piston rod 44 unchanged, so that the air in the piston cylinder 41 is discharged through the air outlet pipe 42 through the silicone plate on the left piston rod 44, and the welding slag on the sheet metal is blown away; when the piston cylinder 41 moves to the right, under the action of the right piston rod 44, the air inside the piston cylinder 41 is pressurized and discharged from the air outlet pipe 42, and the left piston rod 44 will be stretched, so that the position of the left piston rod 44 remains unchanged, and under the action of the air discharge force, the welding slag on the sheet metal is cleaned to prevent cracks from appearing at the welding interface, thereby improving the quality of welding.

[0035] The pressure of air exhaust may be too low, which may cause welding slag on the sheet metal to remain when cleaning. When the piston cylinder 41 moves to the right, the piston cylinder 41 is separated by the silicone plate 51, so that when the piston cylinder 41 moves to the right, the air in the piston cylinder 41 is exhausted through the piston rod 44 on the right, and under the action of the silicone plate 51, the air in the piston cylinder 41 is exhausted from an air outlet pipe 42 to increase the pressure of air exhaust. When the two silicone plates 51 are in contact, the piston cylinder 41 on the right pushes the silicone plate 51 to move through the spring three 52, and the silicone plate 51 passes through the protruding block on the telescopic rod 55. The arc plate 54 is driven to move, thereby squeezing the spring four 56 to generate elastic force, so that the arc plate 54 moves to open the middle air outlet pipe 42, so that the air is discharged from the middle air outlet pipe 42. Because the edge of the silicone plate 51 is soft, when the arc plate 54 moves to the leftmost position, the silicone plate 51 can pass through. Under the action of the elastic force of the spring four 56, the arc plate 54 is reset to block the middle air outlet pipe 42, so that the air is discharged from the left air outlet pipe 42. When the piston cylinder 41 moves to the left, the air is discharged in this operating mode, thereby increasing the pressure of the air discharge and improving the cleaning effect.
