The movement of the connecting rod will push the pressure plate to move, so as to press and fix the steel plate. Fixing the steel plate can effectively prevent displacement caused by thermal expansion during the welding process and ensure the accurate position and alignment of the welding joint.

[0007] According to the above technical solution, a first torsion spring is provided between the cross bar and the sliding table. The first torsion spring is provided to drive the cross bar back to its original position. A first spring is provided between the push plate and the placement table. The first spring is provided to drive the push plate back to its original position. The upper surface of the workbench is fixedly installed with a slideway.

The scraping plate is fixedly installed at one end of the second hydraulic rod away from the second hydraulic cylinder. The knocking rod is rotatably installed on one side of the scraping plate close to the long plate. When the knocking rod contacts the welded surface, it will be continuously bounced up because the welded surface is too rough. After the knocking rod is bounced up, it will be quickly pulled back by the third torsion spring to strike the welded surface, which can effectively remove the welding slag during the welding process. Appropriate knocking can improve the toughness of the metal, making it less likely to undergo brittle fracture under stress.

[0012] According to the above technical solution, the first hydraulic cylinder and the second hydraulic cylinder are connected through a hose. A second spring is provided between the first hydraulic cylinder and the first hydraulic rod. The second spring is provided to drive the first hydraulic rod back to its original position.

[0014] The present invention provides an auxiliary tooling for welding a decoration bracket. It has the following beneficial effects: (1)When welding steel plates, place the steel plates to be welded on the surface of the placement table. After the steel plates are placed, start the telescopic table. Starting the telescopic table will pull the placement table downward. The downward movement of the placement table will drive the push rod to move. The movement of the push rod will push the push plate to slide, straightening the placed steel plates, aligning the two steel plates to be welded together. Aligning the steel plates can effectively reduce the deformation caused by thermal expansion during welding, ensuring the stability of the structure and the dimensional accuracy after welding. The push rod will press the cross bar to rotate. The rotation of the cross bar will drive the short rod to rotate. The rotation of the short rod will push the connecting rod to move. The movement of the connecting rod will push the pressing plate to move, pressing and fixing the steel plates. Fixing the steel plates can effectively prevent displacement caused by thermal expansion during welding, ensuring the accurate position and alignment of the welded joints.

[0015] (2)When placing the steel plates, one side of the steel plate needs to be attached to the long plate. When pressing the steel plates, the cross bar will rotate. The rotation of the cross bar will drive the first gear shaft to rotate. The rotation of the first gear shaft will push the rack to move. The movement of the rack will push the second gear shaft to rotate. The rotation of the second gear shaft will drive the square rod to rotate. The rotation of the square rod will drive the long plate to rotate towards the inside of the sliding table. The rotation of the long plate will drive the rotating rod to rotate. By attaching the steel plates to the long plate, the two steel plates can be attached together during welding, ensuring uniform stress distribution, thereby improving the strength and durability of the overall structure. The rotation of the long plate will release the block on the steel plate to avoid affecting welding. When the long plate rotates into the sliding table, it will push the L-shaped plate to slide. The sliding of the L-shaped plate will drive the baffle to move. The movement of the baffle will release the contact with the slideway groove, enabling the sliding table to drive the steel plate towards the center of the workbench without being blocked by the baffle during welding, effectively avoiding welding the steel plates when they are not pressed and aligned, which will have a certain impact on subsequent welding.

[0016] (3)When the L-shaped plate slides, it will drive the sliding rod to move. The sliding rod will contact the inclined surface of the inclined block, and then the sliding rod will push the inclined block to move. The movement of the inclined block will push the first hydraulic rod into the first hydraulic cylinder. The increase in the liquid in the second hydraulic cylinder will push the second hydraulic rod away from the second hydraulic cylinder. The movement of the second hydraulic rod will push the scraper to move. The movement of the scraper will clean the excess impurities on the surface of the steel plate. A clean surface helps to form a stronger welded joint, improving the strength of the weld and the durability of the overall structure. When the knocking rod contacts the welded surface, it will be continuously bounced up due to the roughness of the welded surface. After being bounced up, the knocking rod will be quickly pulled back by the third torsion spring to knock on the welded surface, effectively removing the welding slag during welding. Appropriate knocking can improve the toughness of the metal, making it less likely to undergo brittle fracture under stress. Brief Description of the Drawings

The first gear shaft 201 is fixedly installed on the right side of the cross bar 15. The rack 202 is slidably installed on the inner wall of the sliding table 6. The second gear shaft 203 is rotatably installed on the inner wall of the sliding table 6. The square rod 204 is fixedly installed at one end of the second gear shaft 203 away from the sliding table 6. The rotating rod 205 is rotatably installed on one side of the placing table 7 close to the second gear shaft 203.

When the long plate 206 rotates into the sliding table 6, it will push the L-shaped plate 207 to slide. The sliding of the L-shaped plate 207 will drive the baffle 208 to move. The movement of the baffle 208 will release the contact with the slideway groove, so that when welding is required, the sliding table 6 drives the steel plate to move towards the center of the workbench 1 without being blocked by the baffle 208, which can effectively avoid welding the steel plate when it is not pressed and aligned, having a certain impact on subsequent welding.

[0025] The rack 202 meshes with the first gear shaft 201 and the second gear shaft 203 respectively. A second torsion spring is provided between the baffle 208 and the L-shaped plate 207. The second torsion spring is provided to drive the baffle 208 back to its original position to seal the sliding groove. The baffle 208 is in contact with the slideway groove.

The sliding rod 301 is fixedly installed on one side of the L-shaped plate 207 close to the square rod 204. The inclined block 302 is slidably installed at the bottom of the inner wall of the sliding table 6. The first hydraulic cylinder 304 is fixedly installed on the inner wall of the sliding table 6.

The knocking rod 308 is rotatably installed on one side of the scraper 307 close to the long plate 206. When the knocking rod 308 contacts the welded surface, it will be continuously bounced up because the welded surface is too rough. After the knocking rod 308 is bounced up, it will be quickly pulled back by the third torsion spring to strike the welded surface, which can effectively remove the welding slag during the welding process. Appropriate knocking can improve the toughness of the metal, making it less likely to undergo brittle fracture under stress.

[0027] The first hydraulic cylinder 304 and the second hydraulic cylinder 305 are connected through a hose. A second spring is provided between the first hydraulic cylinder 304 and the first hydraulic rod 303 to drive the first hydraulic rod 303 back to its original position.

[0029] When this embodiment works: When placing the steel plate, one side of the steel plate needs to be attached to the long plate 206. When pressing the steel plate, the cross bar 15 will rotate. The rotation of the cross bar 15 will drive the rotation of the first gear shaft 201. The rotation of the first gear shaft 201 will push the rack 202 to move. The movement of the rack 202 will drive the rotation of the second gear shaft 203. The rotation of the second gear shaft 203 will drive the rotation of the square rod 204. The rotation of the square rod 204 will drive the long plate 206 to rotate towards the inside of the sliding table 6. The rotation of the long plate 206 will drive the rotation of the rotating rod 205. The rotation of the long plate 206 will release the blockage of the steel plate to avoid affecting the welding. When the long plate 206 rotates into the sliding table 6, it will push the L-shaped plate 207 to slide. The sliding of the L-shaped plate 207 will drive the movement of the baffle 208. The movement of the baffle 208 will release the contact with the slideway groove.

[0030] When the L-shaped plate 207 slides, it will drive the sliding rod 301 to move.

The movement of the first hydraulic rod 303 will compress the second spring to store energy. When the first hydraulic rod 303 moves into the first hydraulic cylinder 304, it will squeeze the liquid inside the first hydraulic cylinder 304 to move through the hose into the second hydraulic cylinder 305. The increase in the liquid inside the second hydraulic cylinder 305 will push the second hydraulic rod 306 to move away from the second hydraulic cylinder 305. The movement of the second hydraulic rod 306 will push the scraper 307 to move, and the movement of the scraper 307 will clean the excess impurities on the surface of the steel plate. When the sliding rod 301 continues to move and loses contact with the inclined block 302, the second spring will push the first hydraulic rod 303 back to its original position. When the first hydraulic rod 303 returns to its original position, it will pump the excess liquid inside the second hydraulic cylinder 305 back into the first hydraulic cylinder 304. The decrease in the liquid inside the second hydraulic cylinder 305 will pull the second hydraulic rod 306 back to its original position. When the steel plate is welded, the telescopic platform 8 will slowly move upward, then the long plate 206 will slowly move back to its original position. The movement of the long plate 206 back to its original position will drive the sliding rod 301 to move. When the sliding rod 301 moves and contacts the inclined surface of the inclined block 302 again, it will push the scraper 307 again to scrape the welded surface. When the scraper 307 moves, it will drive the knocking rod 308 to move. When the knocking rod 308 contacts the welded surface, it will be continuously bounced up because the welded surface is too rough. After the knocking rod 308 is bounced up, it will be quickly pulled back by the third torsion spring to knock on the welded surface, which can effectively remove the welding slag during the welding process.
