After the engine cover plate 61 is cleaned, the user can pull the pull rods 21 at both side ends to move the two pull rods 21 away from each other. At this time, the pull rods 21 drive the two long racks 22 to move, and through the meshing between the two long racks 22 and the two rotating flat gears 23, the two rotating flat gears 23 will move synchronously. The two transparent observation plates 25 and the protective frame 24 rotate around the position of the rotating flat gear 23, thereby closing the front and rear side ends of the first U-shaped frame 11.

At the same time, the cooling fan 39 located on the two fan brackets 38 can blow air to the welding area during welding, so as to dissipate heat. The present invention provides the grinding block 14 and the first rotating shaft 13 and the sliding limit block 12 and the guide rod 16, so that the device can immediately grind the engine cover plate 61, effectively remove these spatters, make the surface of the welding area smooth, and improve the overall appearance quality of the engine cover. There is no need for subsequent manual grinding by the staff, which effectively improves the work efficiency of the automobile stamping parts welding.

[0037] Working principle:

[0038] In the first step, when the device is welding and assembling the automobile stamping part, the engine cover plate 61 as shown in the figure, the user rotates the adjusting threaded rod 53, and the adjusting threaded rod 53 is threadedly connected with the fourth U-shaped frame 52 to move the adjusting threaded rod 53 upward, and the adjusting threaded rod 53 will drive the third U-shaped frame 51 to move upward through the bearing when moving, and the third U-shaped frame 51 will drive the two fan brackets 38 and the second fixed ring 37 and the second clamping rotating plate 35 to move upward, and the position between the second clamping rotating plate 35 and the first clamping rotating plate 34 is vacant. At this time, the user places the engine cover plate 61 on the two supporting glues at the upper end of the first clamping rotating plate 34, and then Then, the adjusting threaded rod 53 is rotated in the opposite direction to move downward, thereby driving the second clamping rotating plate 35 and the two supporting rubbers at its lower end to move downward, so that the engine cover 61 can be clamped between the first clamping rotating plate 34 and the second clamping rotating plate 35. At this time, the engine cover 61 is divided into an inner plate and an outer plate, and the side joints are not welded. The fan bracket 38 and the cooling fan 39 provided in the present invention can effectively control the temperature of the welding area, so that the metal material can shrink more evenly during the cooling process. The cooling fan 39 accelerates the air flow to take away the heat, which helps to reduce this deformation, thereby ensuring the shape accuracy of the engine cover and enabling it to be better installed in coordination with other parts of the vehicle body.

[0039] In the second step, before welding, the user turns on the water pump between the cleaning water tank 44 and the water tank bracket 45, and rinses the connection between the inner plate and the outer plate in the engine cover 61 through the water spray assembly in the water tank bracket 45. During the rinsing process, the user controls the second servo motor 32 to work, so that the second servo motor 32 drives the second rotating shaft 33 to rotate through the output shaft, and the second rotating shaft 33 drives the first clamping rotating plate 34 to rotate, and the first clamping rotating plate 34 is rotatably installed in the first fixed ring 36, and at this time, the second clamping rotating plate 35 and the first clamping rotating plate 34 are in a close fit with the engine cover 61, so the engine cover 61 will rotate accordingly, so that the engine cover 61 can be rotated and cleaned, and while cleaning, use Turn on the blower 42 and the electric heating wire of the heating component 43. The blower 42 can blow the heat emitted from the inside of the heating component 43 to the place where the inner plate and the outer plate of the engine cover 61 are connected, so as to dry the water after cleaning, and the cleaning sponge 41 arranged at the lower end of the heating component 43 can wipe the water. The present invention provides a cleaning water tank 44 and a water tank bracket 45 as well as a blower 42 and a heating component 43, so that the device can effectively remove oil stains and impurities on the stamping parts, ensure the purity of the welding molten pool, thereby improving the welding quality and ensuring the welding strength of the outer plate and the inner plate of the engine cover. At the same time, cleaning can also remove the oxide layer, rust, etc. on the surface of the stamping parts. The metal surface after cleaning is smoother, which is conducive to fusion during welding, makes the weld more uniform and dense, and improves the quality of the welded joint.

[0040] In the third step, after the engine cover 61 is cleaned, the user can pull the pull rods 21 at both ends to move the two pull rods 21 away from each other. At this time, the pull rods 21 drive the two long racks 22 to move, and through the engagement between the two long racks 22 and the two rotating flat gears 23, the two rotating flat gears 23 will rotate synchronously, and at this time, the two transparent observation plates 25 and the protective frame 24 will be driven to rotate around the position of the rotating flat gears 23, thereby closing the front and rear side ends of the first U-shaped frame 11. At this time, the user can remove the welding equipment from the two first U-shaped frames 1 1, so that the welding operation hole 18 opened at the side end can be inserted into the welding operation hole 18, so that the connection place of the inner plate and the outer plate in the engine cover plate 61 can be welded. The present invention can effectively block the splashes and prevent them from contacting the operator by setting the rotatable protective frame 24 and the transparent observation plate 25, thereby reducing the risk of injury to the operator. The protective frame 24 and the transparent observation plate 25 are like a barrier to isolate the splashes from the operator. At the same time, the transparent design of the transparent observation plate 25 can facilitate the staff to observe the welding place during welding.

[0041] In the fourth step, while welding, the user turns on the first servo motor 15 to make the first servo motor 15 work. The first servo motor 15 drives the first rotating shaft 13 to rotate through the output shaft, and the first rotating shaft 13 drives the grinding block 14 to rotate. The grinding block 14 is located at the place where the inner plate and the outer plate are connected in the engine cover 61. When the welding equipment completes welding of the engine cover 61, the grinding block 14 can grind the welding place, so that the welded place can be polished at the same time as welding, so as to achieve the effect of removing the barbs at the welding place of the automobile stamping parts. At the same time, the cooling fan 39 located on the two fan brackets 38 can blow air to the welding part during welding, so as to dissipate heat. The present invention provides the grinding block 14 and the first rotating shaft 13 as well as the sliding limit block 12 and the guide rod 16, so that the device can immediately grind the engine cover 61, effectively remove these spatters, make the surface of the welding place smooth, improve the overall appearance quality of the engine cover, and do not need the staff to perform subsequent manual grinding, which effectively improves the work efficiency of the automobile stamping parts welding.

[0042] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description.
