[0013] 1. The present utility model is provided with a cleaning assembly. The mother-magic tape on the cleaning cotton ring is adhered to the sub-magic tape on the limiting roller, so that the cleaning cotton ring can be covered on the limiting roller. After the bottom end of the limiting roller moves to contact the upper end of the thin plate, the driving motor is started. The driving motor drives the bidirectional screw rod to rotate. The rotation of the bidirectional screw rod drives the two threaded sleeves to move towards or away from each other. The movement of the threaded sleeve drives the U-shaped frame to move. The movement of the U-shaped frame drives the limiting roller to rotate and move. The rotation and movement of the limiting roller drive the cleaning cotton ring to rotate and move.

[0023] Embodiment 1

[0024] Please refer to Figures 1-6 , the present invention provides the following technical solutions: A welding auxiliary device for thin plate welded parts, including a workbench 1. An elevating plate 4 is arranged inside the workbench 1. An elevating mechanism 7 is arranged between the workbench 1 and the elevating plate 4. Limiting rollers 5 are arranged at both ends below the elevating plate 4. A cleaning component 3 is arranged between the elevating plate 4 and the limiting rollers 5. Support plates 2 are arranged on both sides inside the workbench 1 and below the limiting rollers 5. Pressing components 8 are arranged at the mutually remote ends of the two support plates 2. A driving mechanism 6 is arranged between the workbench 1 and the support plates 2.

A driving member 35 is arranged between the U-shaped frame 31 and the elevating plate 4.

[0026] By adopting the above technical solution, after placing the thin plate welded part on the support plate 2, the driving member 35 is used to drive the U-shaped frame 31 to move. The movement of the U-shaped frame 31 drives the limiting roller 5 to rotate and move. The rotation and movement of the limiting roller 5 drive the cleaning cotton ring 32 to rotate and move. During the rotation and movement of the cleaning cotton ring 32, the thin plate welded part can be cleaned, ensuring the cleanliness of the surface of the thin plate welded part, and thus ensuring the welding effect of the subsequent thin plate welded part.

[0027] Specifically, the driving member 35 includes a bidirectional screw 351, a moving cavity 352, a threaded sleeve 353, and a driving motor 354. One end of the elevating plate 4 is connected to the driving motor 354. The output end of the driving motor 354 is connected to the bidirectional screw 351. A moving cavity 352 is arranged on the elevating plate 4 at a position corresponding to the bidirectional screw 351. A threaded sleeve 353 is connected to the outer periphery of the bidirectional screw 351 on the side of the U-shaped frame 31 close to the elevating plate 4.

[0028] By adopting the above technical solution, start the driving motor 354. Use the driving motor 354 to drive the bidirectional screw 351 to rotate. The rotation of the bidirectional screw 351 drives the two threaded sleeves 353 to move towards or away from each other inside the moving cavity 352. The movement of the threaded sleeve 353 drives the U-shaped frame 31 to move.

[0029] Specifically, the cleaning component 3 further includes a male magic tape 33 and a female magic tape 34. The male magic tape 33 is connected to the outer sidewall of the limiting roller 5, and the female magic tape 34 is connected to one side of the cleaning cotton ring 32 close to the male magic tape 33.

[0030] By adopting the above technical solution, the female magic tape 34 on the cleaning cotton ring 32 is adhered to the male magic tape 33 on the limiting roller 5, so that the cleaning cotton ring 32 can be laminated onto the limiting roller 5, facilitating the disassembly and assembly operations of the cleaning cotton ring 32.

[0031] When this embodiment is in use, the female magic tape 34 on the cleaning cotton ring 32 is adhered to the male magic tape 33 on the limiting roller 5, so that the cleaning cotton ring 32 can be laminated onto the limiting roller 5. Then, the two thin plates to be welded are respectively placed on the upper ends of the two side support plates 2, and one side of the thin plate is in contact with the vertical part of the support plate 2. Then, the lifting mechanism 7 is used to drive the lifting plate 4 to move. The movement of the lifting plate 4 drives the bottom end of the limiting roller 5 to move into contact with the upper end of the thin plate. Then, the driving motor 354 is started, and the driving motor 354 is used to drive the bidirectional screw 351 to rotate. The rotation of the bidirectional screw 351 drives the two threaded sleeves 353 to move towards or away from each other inside the moving cavity 352. The movement of the threaded sleeve 353 drives the U-shaped frame 31 to move. The movement of the U-shaped frame 31 drives the limiting roller 5 to rotate and move. The rotation and movement of the limiting roller 5 drive the cleaning cotton ring 32 to rotate and move. During the rotation and movement of the cleaning cotton ring 32, the thin plate welded part can be cleaned, ensuring the cleanliness of the surface of the thin plate welded part, and further ensuring the welding effect of the subsequent thin plate welded part. Then, the driving mechanism 6 is used to drive the support plate 2 to move. The movement of the support plate 2 drives the two thin plates to move. When the ends of the two thin plates are mutually attached, the driving mechanism 6 is stopped, facilitating the cleaning and limiting operations of the two thin plate welded parts, and assisting the operator to complete the welding operation of the two thin plate welded parts.

[0032] Embodiment 2

[0033] The difference between this embodiment and Embodiment 1 lies in that the pressing component 8 includes a connecting spring 81, a pushing block 82, a pressing block 83, and a pushing cavity 84. A pushing cavity 84 is provided on the inner sidewall of the support plate 2. The pushing block 82 is inserted into the pushing cavity 84. A connecting spring 81 is connected between the pushing block 82 and the pushing cavity 84. One end of the pushing block 82 is connected with a pressing block 83.

[0034] Specifically, the pressing component 8 further includes an end block 85 and a tightening screw 86. An end block 85 is connected to one end of the support plate 2 and above the pushing cavity 84. A tightening screw 86 is connected inside the end block 85.

[0035] By adopting the above-mentioned technical scheme, after the clamping block 83 is used to clamp the thin plate weldment, the clamping screw 86 is rotated to rotate and move along the end block 85. When the clamping screw 86 moves to fit the side wall of the clamping block 83, the rotation of the clamping screw 86 is stopped, and the clamping screw 86 is used to clamp the clamping block 83 to ensure the clamping effect of the clamping block 83 on the thin plate weldment.

[0036] When the present embodiment is used, the pressing block 83 is moved upward, and the pressing block 83 moves upward to drive the pushing block 82 to move upward along the pushing cavity 84. The pushing block 82 moves upward to squeeze the connecting spring 81, and then the two thin plates to be welded are placed on the upper ends of the support plates 2 on both sides, and one side of the thin plate is in contact with the vertical part of the support plate 2, and then the pushing block 82 is released, and the connecting spring 81 loses the external force and restores its original appearance, driving the pushing block 82 to move downward inside the pushing cavity 84, and the pushing block 82 moves downward to drive the pressing block 83 to move downward. When the pressing block 83 moves to fit the thin plates After the upper surface of the welded part is reached, the clamping screw 86 is rotated again to make it rotate and move along the end block 85. When the clamping screw 86 moves to fit the side wall of the clamping block 83, the rotation of the clamping screw 86 is stopped, and the clamping screw 86 is used to perform a clamping operation on the clamping block 83 to ensure the clamping effect of the clamping block 83 on the end of the thin plate welded part. This can prevent the end of the thin plate welded part close to the vertical part of the support plate 2 from tilting when the limiting roller 5 is used to limit the other end of the thin plate welded part, thereby affecting the stability of the placement of the thin plate welded part.

[0037] The driving motor 354 in the present invention is an existing disclosed technology, and the selected model is TCB6334.

When in use, the double-threaded screw is driven to rotate by the handle, and the rotation of the double-threaded screw drives the threaded block to move toward or away from each other.

[0039] The structure and principle of the lifting mechanism 7 composed of a telescopic rod, a threaded barrel and a screw rod in the utility model have been disclosed in a clamping auxiliary device for thin plate welding disclosed in Chinese patent application No. 202122120583.X, and its working principle is: the threaded barrel is rotatably arranged on the top plate of the workbench 1, and a bearing is arranged at the connection between the threaded barrel and the workbench 1, and a swivel is arranged on the outer fixed sleeve of the threaded barrel, and a screw rod is connected to the inner thread of the threaded barrel, and the bottom end of the screw rod is connected to the top end of the lifting plate 4, and a telescopic rod is connected between the workbench 1 and the lifting plate 4. When in use, the threaded barrel is rotated to drive the screw rod to move, and the movement of the screw rod drives the lifting plate 4 to move, and the movement of the lifting plate 4 drives the telescopic rod to extend and retract.

[0040] The working principle and use process of the utility model are as follows: the utility model adheres the female Velcro 34 on the cleaning cotton ring 32 to the sub Velcro 33 on the limiting roller 5, so that the cleaning cotton ring 32 can be covered on the limiting roller 5, and the pressing block 83 is moved upward. The pressing block 83 moves upward to drive the push block 82 to move upward along the push cavity 84, and the push block 82 moves upward to squeeze the connecting spring 81, and then the two thin plates to be welded are placed on the upper ends of the support plates 2 on both sides, and one side of the thin plate is in contact with the vertical part of the support plate 2, and the push block 82 is released, and the connecting spring 81 loses the external force and returns to its original state. The pushing block 82 moves downward in the pushing cavity 84, and the pushing block 82 moves downward, driving the pressing block 83 to move downward. When the pressing block 83 moves to fit the upper surface of the thin plate weldment, the tightening screw 86 is rotated to make it rotate and move along the end block 85. When the tightening screw 86 moves to fit the side wall of the pressing block 83, the rotation of the tightening screw 86 is stopped, and the tightening screw 86 is used to tighten the pressing block 83 to ensure the tightening effect of the pressing block 83 on the end of the thin plate weldment, thereby avoiding the subsequent use of the limiting roller 5 to limit the other end of the thin plate weldment. The end of the thin plate welding part close to the vertical part of the support plate 2 is tilted, affecting the stability of the placement of the thin plate welding part, and then the lifting mechanism 7 is used to drive the lifting plate 4 to move, and the movement of the lifting plate 4 drives the bottom end of the limiting roller 5 to move and contact the upper end of the thin plate, and then the driving motor 354 is started, and the driving motor 354 is used to drive the bidirectional screw 351 to rotate, and the rotation of the bidirectional screw 351 drives the two threaded sleeves 353 to move toward or away from each other in the moving cavity 352, and the movement of the threaded sleeve 353 drives the U-shaped frame 31 to move, and the movement of the U-shaped frame 31 drives the limiting roller 5 to rotate and move The limiting roller 5 rotates and moves, driving the cleaning cotton ring 32 to rotate and move. During the rotation and movement of the cleaning cotton ring 32, the thin plate welded parts can be cleaned to ensure the cleanliness of the surface of the thin plate welded parts, thereby ensuring the welding effect of the subsequent thin plate welded parts. Then the driving mechanism 6 is used to drive the support plate 2 to move, and the movement of the support plate 2 drives the two thin plates to move.
