The rotation of the hexagonal block drives the threaded rod to rotate, and the rotation of the threaded rod will cause the threaded sleeve to move.

The pressing end of the pressing piece is located on the displacement track of one side of the arc of the abutment block. The pressing piece is used to control the welding seam magnetic powder inside the powder storage box to be ejected from the nozzle through the connecting tube and the long tube. When the welding is completed, the hexagonal block is rotated in the opposite direction, so that the threaded rod is rotated in the opposite direction. The reverse rotation of the threaded rod will cause the threaded sleeve to move in the opposite direction. The movement of the threaded sleeve will drive the movable arc plate to move in the opposite direction. The reverse movement of the movable arc plate drives the bidirectional elastic telescopic ring away from the supporting block, so the torsion spring will reset by its own elastic force.

[0009] According to the above technical scheme, an anti-adhesion device is provided on the side of the arc plate located on one side of the movable arc plate, and the anti-adhesion device includes a bracket, the side of the bracket is fixedly connected to the side of the arc plate, the inner wall of the bracket is slidably connected to an arc scraper block, the top of the bracket passes through and slides with a push rod, the bottom of the push rod is fixedly connected to the top of the arc scraper block, the top of the push rod is fixedly connected with a pressing block, and the side of the bracket passes through and slides with a second latch for fixing the arc scraper block. Before the bottom of the tank is adsorbed and fixed by the adsorption hollow disk, the staff pulls open the second latch so that the second latch no longer fixes the arc scraper block, and then presses the pressing block to drive the arc scraper block to move through the push rod.

[0010] According to the above technical solution, the side of the pressing block is fixedly connected with a long plate, the side of the long plate is fixedly connected with a plurality of triangular blocks, the side of the hexagonal block is penetrated and slidably provided with a long rod, the outer wall of the long rod is slidably installed on the inner wall of the threaded rod, one end of the long rod is fixedly connected with a pulling block, the other end of the long rod is fixedly connected with a round block, the outer wall of the round block is fixedly connected with a plurality of elastic plates, a gap is provided between the round block and the threaded rod, a spring is provided between the pulling block and the hexagonal block, the arc-shaped scraping block is in contact with the arc-shaped plate, a gap is provided between the round block and the threaded rod, and when the pressing block moves downward, the pressing block The long board is driven to move downward, and the downward movement of the long board drives the triangular block to move downward. The inclined surface of the triangular block will first hit the elastic plate, causing the elastic plate to deform. At this time, the triangular block will pass over the elastic plate. When the threaded rod has a tendency to rotate in the opposite direction, the right-angle surface of the triangular block will restrict the elastic plate, so that the elastic plate can restrict the movement trajectory of the threaded rod with reverse rotation through the round block, thereby avoiding accidentally touching the hexagonal block and causing inaccurate movement of the moving arc plate. When the moving arc plate needs to be folded up, pull the pull block, and the movement of the pull block drives the long rod to move, and the movement of the long rod drives the round block to move.

[0011] The present invention provides a carbon can production welding device with stable welding. It has the following beneficial effects:

[0012] (1) The present invention enables a certain gap to exist between the two arc plates by means of the coordination of a fixed block, an electric push rod, a cylinder, a U-shaped plate, an adjustment groove, a latch pin, an arc plate, and a hollow arc block. Since the two arc plates are parallel to the welding points of the tank body and the tank bottom, respectively, there is a certain gap at the welding points of the tank body and the tank bottom. The existence of the gap can help compensate for the expansion difference between the tank body and the tank bottom caused by temperature changes, thereby avoiding deformation or structural damage caused by expansion. At the same time, by means of the coordination of a movable arc plate, a placement plate, a threaded rod, a threaded sleeve plate, a finger plate, a hexagonal block, and a scale plate, the movement of the threaded sleeve plate will drive the movement of the movable arc plate. The staff can judge the distance that the threaded sleeve plate pushes the movable arc plate to move by the position pointed by the finger plate on the scale plate, thereby realizing the situation where the gap is adjusted according to the thickness welding of the tank body and the tank bottom.

[0013] (2) The present invention cooperates with the powder storage box, the pressing piece, the limit block, the rotating rod, the resistance block, the torsion spring, the support block and the L-shaped rod so that the rotation of the rotating rod drives the resistance block to rotate. The rotation of the resistance block presses the pressing end of the pressing piece, so that the weld magnetic powder inside the powder storage box is sprayed from the nozzle to the welds of the tank body and the tank bottom through the connecting pipe and the long pipe. When there is a defect in the weld, a leakage magnetic field will be generated, thereby attracting magnetic powder. By observing the distribution of the magnetic powder, it can be determined whether there is a defect in the weld. At the same time, through the cooperation of the resistance block, the torsion spring, the support block and the L-shaped rod, the rotation of the resistance block and the rotating rod will cause the torsion spring to deform. The rotation of the resistance block will no longer be in the same horizontal plane with the pressing end of the pressing piece. Therefore, when the welding assembly is welding the tank body and the tank bottom, it will not be affected by the weld magnetic powder inside the powder storage box.

[0014] (3) The present invention cooperates with the bracket, arc scraper block, push rod, long plate, push block and latch, so that the push block drives the arc scraper block to move through the push rod. The movement of the arc scraper block will clean up the adhesion on the side of the movable arc plate, thereby preventing the adhesion from affecting the docking of the movable arc plate and the hollow arc block, resulting in the gap between the tank body and the tank bottom being difficult to reach the required distance; at the same time, through the cooperation of the triangular block, long rod, round block, elastic plate and pulling block, the movement of the pulling block drives the movement of the long rod, the movement of the long rod drives the movement of the round block, and the movement of the round block drives the movement of the elastic plate, so that the elastic plate and the triangular block are no longer located in the same plane. At this time, the hexagonal block can drive the threaded rod to rotate in the opposite direction. BRIEF DESCRIPTION OF THE DRAWINGS

The side of the arc plate 77 on one side of the fixed component 12 is fixedly connected to a hollow arc block 78. Through the arrangement of the above structure, the movement of the hollow arc block 78 will preferentially contact the other arc plate 77, so that there is a certain gap between the two arc plates 77. Since the two arc plates 77 are respectively parallel to the welding points of the tank body and the tank bottom, there is a certain gap between the welding points of the tank body and the tank bottom. The existence of the gap can help compensate for the expansion difference between the tank body and the tank bottom caused by temperature changes, thereby avoiding deformation or structural damage caused by expansion.

[0027] A movable arc plate 79 is penetrated and slidably provided on the side of the arc plate 77 located on one side of the adsorption hollow disk 13, a placement plate 710 is fixedly connected to the outer wall of the arc plate 77 located on one side of the adsorption hollow disk 13, a threaded rod 711 is penetrated and rotatably provided on the side of the placement plate 710, a threaded sleeve plate 712 is threadedly connected to the outer wall of the threaded rod 711, a side of the threaded sleeve plate 712 is fixedly connected to the side of the movable arc plate 79, a finger plate 713 is fixedly connected to the side of the threaded sleeve plate 712, and a hexagonal block 71 is fixedly connected to one end of the threaded rod 711 away from the placement plate 710 4.

The side of the finger plate 713 away from the threaded sleeve 712 is in contact with the side of the scale plate 715. Through the arrangement of the above structure, the movement of the threaded sleeve 712 will drive the movable arc plate 79 to move. The staff can judge the distance that the threaded sleeve 712 pushes the movable arc plate 79 to move by the position pointed by the finger plate 713 on the scale plate 715, thereby realizing the situation that the gap is adjusted according to the thickness of the tank body and the tank bottom.

[0028] A detection device 8 is provided on the side of the arc-shaped plate 77 on one side of the adsorption hollow disk 13. The detection device 8 includes a powder storage box 81. The side of the powder storage box 81 is fixedly connected to the side of the arc-shaped plate 77. A pressing piece 82 is fixedly connected to the top of the powder storage box 81. A connecting pipe 810 is fixedly connected to the side of the powder storage box 81. The end of the connecting pipe 810 away from the powder storage box 81 is fixedly connected to a long tube 811. The bottom of the long tube 811 is fixedly connected to the inner wall of the arc-shaped plate 77. A plurality of nozzles 812 are fixedly connected to the top of the long tube 811. A limiting block 83 is fixedly connected to the side of the adsorption hollow disk 13. A rotating rod 84 is rotatably connected to the side of the limiting block 83. A resistance block 85 is fixedly connected to the end of the rotating rod 84 away from the limiting block 83. A torsion spring 86 is provided between the resistance block 85 and the limiting block 83. A supporting block 87 is fixedly connected to the side of the resistance block 85. A plurality of L-shaped rods 88 are fixedly connected to the side of the movable arc plate 79. 8. A bidirectional elastic telescopic ring 89 is fixedly connected to one side of several L-shaped rods 88 away from the movable arc plate 79. The support block 87 is located on the movement trajectory of the bidirectional elastic telescopic ring 89. The side of the resistance block 85 away from the support block 87 is set to an arc shape. The pressing end of the pressing piece 82 is located on the displacement trajectory of the arc side of the resistance block 85. The pressing piece 82 is used to control the welding magnetic powder inside the powder storage box 81 to be sprayed out from the nozzle 812 through the connecting pipe 810 and the long tube 811. Through the setting of the above structure, the rotation of the rotating rod 84 drives the resistance block 85 to rotate. The rotation of the resistance block 85 will press the pressing end of the pressing piece 82, so that the welding magnetic powder inside the powder storage box 81 is sprayed from the nozzle 812 to the welding seam of the tank body and the bottom of the tank through the connecting pipe 810 and the long tube 811. When there is a defect in the welding seam, a leakage magnetic field will be generated, thereby attracting magnetic powder. By observing the distribution of magnetic powder, it can be judged whether there is a defect in the welding seam.

[0029] When in use, the tank body and the tank bottom of the carbon canister are fixed by the fixing assembly 12 and the adsorption hollow disk 13 respectively, and then the two electric push rods 10 are started. The telescopic ends of the two electric push rods 10 will drive the tank body and the tank bottom to approach each other through the two drivers 11, and drive the two drivers 11 to make the fixing assembly 12 and the adsorption hollow disk 13 drive the tank body and the tank bottom to rotate, and then the tank body and the tank bottom are welded by the welding assembly 5. After the tank body is fixed by the fixing assembly 12, the pin 76 is taken out from the inner wall of the adjustment groove 75, and then the U-shaped plate 74 is pushed to move the cylinder 73 on the inner wall of the fixing block 72 to fix it. The movement of block 72 drives the arc plate 77 to move, so that the arc plate 77 is parallel to the welding part of the tank body, and the arc plate 77 is also parallel to the welding part of the tank bottom according to the above operation. The telescopic ends of the two electric push rods 10 drive the fixed assembly 12 and the adsorption hollow disk 13 to drive the tank body and the tank bottom to approach each other through the two drivers 11. The telescopic ends of the electric push rods 10 drive the through-hole round frame 71 to move, and the movement of the through-hole round frame 71 drives the fixed block 72 to move, and the movement of the fixed block 72 drives the cylinder 73 to move, and the movement of the cylinder 73 drives the arc plate 77 to move, so that the two arc plates 77 are close to each other, and the fixed block 72 drives the cylinder 73 to move. The movement of the cylinder 73 drives the arc plate 77 to move, so that the two arc plates 77 are close to each other. The arc plate 77 on one side of the component 12 moves while driving the hollow arc block 78 to move. The movement of the hollow arc block 78 will first contact the other arc plate 77, so that there is a certain gap between the two arc plates 77. Since the two arc plates 77 are parallel to the welding points of the tank body and the tank bottom, there is a certain gap between the welding points of the tank body and the tank bottom. The existence of the gap can help compensate for the expansion difference between the tank body and the tank bottom caused by temperature changes, and avoid deformation or structural damage caused by expansion; the hexagonal block 714 is rotated according to the different thicknesses of the tank body and the tank bottom. The rotation of the hexagonal block 714 drives the threaded rod 711 to rotate, and the rotation of the threaded rod 711 causes the threaded sleeve The plate 712 moves, and the movement of the threaded sleeve 712 will drive the finger plate 713 to move on the surface of the scale plate 715. At the same time, the movement of the threaded sleeve 712 will drive the movable arc plate 79 to move. The staff can judge the distance that the threaded sleeve 712 pushes the movable arc plate 79 to move by the position pointed by the finger plate 713 on the scale plate 715, thereby adjusting the gap according to the thickness of the tank body and the tank bottom. Under normal circumstances, the finger plate 713 is adjusted by 0.5 mm on the scale plate 715, so that the movable arc plate 79 just fits the inner wall of the hollow arc block 78. According to the changes in the thickness of the tank body and the tank bottom, the adjustment range is switched between 0.5 mm and 2 mm.

[0030] When the movable arc plate 79 moves 0.5 mm, it will drive the L-shaped rod 88 to move 0.5 mm. The movement of the L-shaped rod 88 will drive the bidirectional elastic telescopic ring 89 to move 0.5 mm. The movement of the bidirectional elastic telescopic ring 89 by 0.5 mm will contact the support block 87, so that the support block 87 drives the rotating rod 84 to rotate through the contact block 85. The rotation of the contact block 85 and the rotating rod 84 will cause the torsion spring 86 to deform. The rotation of the contact block 85 will no longer be located in the same horizontal plane as the pressing end of the pressing piece 82. Therefore, when the welding assembly 5 welds the tank body and the tank bottom, it will not be affected by the magnetic powder of the weld inside the powder storage box 81. After the welding is completed, the hexagonal block 714 is rotated in the opposite direction, so that the threaded rod 711 rotates in the opposite direction. The reverse rotation of the threaded rod 711 will cause the threaded sleeve 712 to move in the opposite direction. The movement of the threaded sleeve 712 will drive the movable arc plate 79 to move in the opposite direction. The movement drives the bidirectional elastic telescopic ring 89 away from the supporting block 87, so the torsion spring 86 will be reset by its own elastic force, and the reset of the torsion spring 86 will drive the resistance block 85 and the rotating rod 84 to reset, so the resistance block 85 will be in the same horizontal plane with the pressing end of the pressing piece 82, and then continue to start the driver 11, the driver 11 will make the adsorption hollow disk 13 rotate, the rotation of the adsorption hollow disk 13 drives the limit block 83 to rotate, the rotation of the limit block 83 drives the rotating rod 84 to rotate, and the rotation of the rotating rod 84 drives the resistance block 85 to rotate, and the rotation of the resistance block 85 will press on the pressing end of the pressing piece 82, so that the weld magnetic powder inside the powder storage box 81 is sprayed from the nozzle 812 to the weld of the tank body and the bottom of the tank through the connecting pipe 810 and the long pipe 811. When there is a defect in the weld, a leakage magnetic field will be generated, thereby attracting magnetic powder. By observing the distribution of the magnetic powder, it is possible to judge whether there is a defect in the weld.

Through the setting of the above structure, the movement of the arc scraper block 92 will clean up the adhesion on the side of the movable arc plate 79, thereby preventing the adhesion from affecting the docking of the movable arc plate 79 with the hollow arc block 78, resulting in the gap between the tank body and the tank bottom being difficult to reach the required distance.

[0032] The side of the pressing block 95 is fixedly connected to a long plate 94, and the side of the long plate 94 is fixedly connected to a plurality of triangular blocks 97. A long rod 98 penetrates and slides through the side of the hexagonal block 714. The outer wall of the long rod 98 is slidably mounted on the inner wall of the threaded rod 711. One end of the long rod 98 is fixedly connected to a pulling block 911, and the other end of the long rod 98 is fixedly connected to a round block 99. The outer wall of the round block 99 is fixedly connected to a plurality of elastic plates 910. A gap is set between the round block 99 and the threaded rod 711. The pulling block 911 and the hexagonal block 714 are connected to each other. A spring is arranged between the blocks 714, the arc scraper block 92 is in contact with the arc plate 77, and a gap is arranged between the round block 99 and the threaded rod 711. Through the arrangement of the above structure, the movement of the pull block 911 drives the long rod 98 to move, the movement of the long rod 98 drives the round block 99 to move, and the movement of the round block 99 drives the elastic plate 910 to move, so that the elastic plate 910 and the triangular block 97 are no longer located in the same plane. At this time, the hexagonal block 714 can drive the threaded rod 711 to rotate in the opposite direction.

[0033] When in use, before the tank bottom is fixed by adsorption of the hollow disk 13, the staff pulls out the second latch 96 so that the second latch 96 no longer fixes the arc scraper block 92, and then presses the pressing block 95 so that the pressing block 95 drives the arc scraper block 92 to move through the push rod 93. The movement of the arc scraper block 92 will clean up the adhesion on the side of the movable arc plate 79, thereby preventing the adhesion from affecting the docking of the movable arc plate 79 with the hollow arc block 78, resulting in the gap between the tank body and the tank bottom being difficult to reach the required distance; when the pressing block 95 moves downward, the pressing block 95 drives the long plate 94 to move downward, and the long plate 94 moves downward and drives the triangular block 97 to move downward, and the inclined surface of the triangular block 97 will first hit the elastic plate 910, thereby causing the elastic plate 910 to deform. Block 97 will pass over the elastic plate 910. When the threaded rod 711 tends to rotate in the opposite direction, the right-angled surface of the triangular block 97 will restrict the elastic plate 910, so that the elastic plate 910 can restrict the movement trajectory of the threaded rod 711 in the opposite direction through the round block 99, thereby avoiding accidentally touching the hexagonal block 714, which causes the movable arc plate 79 to move inaccurately. When the movable arc plate 79 needs to be put away, the pull block 911 is pulled, and the movement of the pull block 911 drives the long rod 98 to move, and the movement of the long rod 98 drives the round block 99 to move, and the movement of the round block 99 drives the elastic plate 910 to move, so that the elastic plate 910 and the triangular block 97 are no longer in the same plane. At this time, the hexagonal block 714 can drive the threaded rod 711 to rotate in the opposite direction.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
