Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, and in particular relates to a welding device for processing an automobile anti-collision beam. Background Art

[0002] The anti-collision beam is a device used to reduce the impact energy of the vehicle when it is hit. It consists of a main beam, an energy absorption box, and a mounting plate connected to the car. The main beam and the energy absorption box can effectively absorb the energy generated by the collision when the vehicle collides at a low speed, and minimize the damage to the longitudinal beam of the vehicle body, thereby protecting the vehicle. After being protected by the anti-collision beam, the damage to the vehicle is reduced, and the maintenance cost is also reduced.

[0003] In the prior art (the announcement number is CN117600724B, and the patent name is a patent application for a welding device for processing automobile anti-collision beams), a clamping part is designed. After the anti-collision beam is placed on the top of the top plate, the staff moves the arc-shaped clamp block to make the square block on the outer surface of the arc-shaped clamp block plug-in and connect to fix the anti-collision beam. Then, the silicone block material and the tooth-marked groove design are used to increase the fixing effect. Through the magnetic part design, the staff moves the magnetic plate upwards to make the support frame slide on the outer surface of the upright slide rail for structural support. At the same time, the magnetic design of the magnetic plate is used to assist the metal anti-collision beam in magnetic connection and fixation. In this way, the support area of ​​the anti-collision beam is expanded to avoid metal weakness caused by high temperature during welding. In the process of implementing this technical solution, it is found that at least the following problems exist in the prior art.

[0004] When welding the main beam and the energy absorption box, the existing device requires workers to manually remove the welded anti-collision beam, and then install the main beam and the energy absorption box for positioning and fixing. This series of actions is completely manual. After welding, the main beam and the energy absorption box are tightly fixed, which makes it difficult to remove the parts and causes deformation of the workpiece. At the same time, due to the uneven distribution of clamping force, the main beam is easily deformed, affecting product quality and making the installation of the energy absorption box more laborious. The sparks generated during the welding process will form welding slag after cooling. These welding slags remain on the device. If they are not thoroughly removed, they will affect the flatness of the subsequent main beam installation. Summary of the invention

[0018] A welding device for processing an automobile anti-collision beam of the present invention:

[0019] 1. The welding device for processing automobile anti-collision beams needs to place the main beam on the arc-shaped plate. The servo motor drives the conveying rod to rotate, and the conveying rod drives the conveyor belt to move.

Therefore, the traditional welding method has certain limitations in terms of safety and product quality.

At the same time, the ejected gas can clean the welding slag formed by the spark after cooling to prevent the welding slag from affecting the flatness of the subsequent main beam installation.

[0053] The working principle of a welding device for processing an automobile anti-collision beam: when in use, the main beam 401 needs to be placed on the arc plate 206, the servo motor 202 drives the conveying rod 203 to rotate, the conveying rod 203 drives the conveying belt 204 to move, and the conveying belt 204 drives the conveying support plate 205 and the arc plate 206 to move to the welding area. The main beam 401 contacts the horizontal positioning frame 402 and the longitudinal positioning frame 403, and the flatness of the main beam 401 can be adjusted to prevent the main beam 401 from being misplaced during welding. When the arc plate 206 is moved to the welding area, the guide shaft 34 slides in the guide groove 37 on the guide plate 36. When the guide shaft 34 moves from the oblique groove on the guide groove 37 to the straight groove farther away from the arc plate 206, the guide shaft 34 Pull the connecting plate 33 to move, and the connecting plate 33 pulls the arc clamping box 304 to move through the L-shaped pulling plate 31, and the arc clamping box 304 moves toward the main beam 401, so that the arc clamping plate 306 clamps the main beam 401, thereby ensuring the stability of the welding process, improving the uniformity of the welding surface and the welding accuracy, and there is no need to manually position and fix the main beam 401, which greatly simplifies the operation process and makes the entire welding process more convenient and efficient. By reducing the dependence on manual operation, it not only reduces the labor intensity of the staff, but also significantly improves the efficiency and quality of the welding operation. The reset spring 305 makes the arc clamping plate 306 and the main beam 401 evenly stressed, which can effectively prevent the deformation of the main beam 401 when it is limited and fixed, thereby improving the product quality.

[0054] The energy absorbing box 404 is placed on the clamping plate 67, and the cylinder 2 62 pulls the pressing circular plate 63 to retract, and the pressing circular plate 63 pulls the clamping plate 65 to move, and the clamping plate 65 drives the clamping plate 67 to clamp the energy absorbing box 404. When the main beam 401 moves to the welding area, the cylinder 1 602 pushes the push seat 603 to rise, and the push seat 603 pushes the push-pull plate 604 to move, and the push-pull plate 604 pushes the flip plate 607 through the connecting rod 605 to fix the seat 606 is an axis flip, so that the energy absorption box 404 on the clamping plate 67 fits with the main beam 401, and then the mechanical arm 104 drives the welding gun 105 to weld the energy absorption box 404 and the main beam 401. After welding, the arc plate 206 is placed away from the welding area, so that the clamping mechanism 3 automatically releases the clamping of the main beam 401, so that the anti-collision beam after welding automatically falls off without manual handling. This automatic operation cycle can significantly improve the efficiency of the welding operation;

[0055] When the conveyor belt 204 drives the arc plate 206 to move to its bottom, the conveyor rod 203 drives the belt 501 to move, and the belt 501 rotates the rotating rod 502, so that the reciprocating block 504 reciprocates along the reciprocating thread groove 503, and the reciprocating block 504 drives the connecting seat 507 and the rotating rod 508 to reciprocate through the lifting rod 506, so that the rotating rod 508 moves along the arc limiting groove plate 51. Because the gear 52 is engaged with the arc tooth plate 53, the rotating rod 508 rotates during the movement, and the rotating rod 508 drives the cleaning roller 509 and the brush 510 to rotate, completing the surface cleaning of the welding position to prevent welding slag The residue on the device affects the next placement of the main beam 401, improves the subsequent welding quality, the rotating rod 502 drives the turntable plate 701 to rotate, the turntable plate 701 pushes and pulls the push-pull rod 702, so that the push-pull rod 702 drives the piston 704 to reciprocate through the transmission seat 703, and the piston 704 moves in the cylinder 705, so that the piston 704 squeezes the gas in the cylinder 705, and the gas is transmitted to the injection rod 706 and discharged from the injection hole 707. The ejected gas cools down the anti-collision beam after welding, which is convenient for the staff to take out the anti-collision beam. At the same time, the ejected gas can clean the welding slag formed by the spark after cooling to prevent the welding slag from affecting the flatness of the subsequent main beam installation.
