[0033] like Figure 2 and Figure 3 As shown, the welding part clamping mechanism 4 includes a connecting sleeve rod 401, the top of the connecting sleeve rod 401 is fixed to the bottom end of the fixed rod 3, and the bottom of the connecting sleeve rod 401 is provided with a rotation slot 409, and the inner side of the rotation slot 409 is plugged with a first rotation adjustment ball 408 for damping rotation. The bottom of the first rotation adjustment ball 408 is fixed with a rotating connecting rod 402, and the bottom end of the rotating connecting rod 402 is slidably installed with a first sliding link 411, and the outer side of the bottom end of the rotating connecting rod 402 is plugged with a first anti-slip screw 403 through a threaded rotation, and the end of the first anti-slip screw 403 passes through the rotating connecting rod 402 and contacts the outer surface of the first sliding link 411, and the bottom end of the rotating connecting sleeve 404 is damped. The second rotating adjustment ball 410 is connected to the rotating card, and a positioning U-shaped plate 405 is fixed to the bottom of the second rotating adjustment ball 410. Both sides of the positioning U-shaped plate 405 are connected with clamping screws 407 through threads. Two welding fixing clips 406 are provided on the inner side of the positioning U-shaped plate 405. One end of the clamping screw 407 is rotated and inserted into the inside of the welding fixing clip 406. The position of the positioning U-shaped plate 405 and the welding fixing clip 406 is changed by the first sliding connecting rod 411. The angles of the positioning U-shaped plate 405 and the welding fixing clip 406 are adjusted by the first rotating adjustment ball 408 and the second rotating adjustment ball 410 to clamp and fix the front connecting plates of automobiles of different sizes and shapes.

[0034] like Figures 6 to 9 As shown, the first rotating adjustment ball 408 can be removed from the inside of the rotating slot 409, and the extended splicing rod 8 can also be detachably installed on the inside of the rotating slot 409. The bottom end of the extended splicing rod 8 is detachably connected to the first rotating adjustment ball 408. The extended splicing rod 8 is added between the connecting sleeve 401 and the first rotating adjustment ball 408 to change the overall length of the welding part clamping mechanism 4 and the position adjustment range of the positioning U-shaped plate 405 and the welding part fixing clip 406, and improve the angle adjustment degree of the positioning U-shaped plate 405 and the welding part fixing clip 406.

[0035] The extended splicing rod 8 includes a middle connecting rod 801, a first rotating connecting ball sleeve 802 is fixed to the top end of the middle connecting rod 801, and a second rotating connecting ball sleeve 803 is fixed to the bottom end of the middle connecting rod 801. The outer diameter of the first rotating connecting ball sleeve 802 is consistent with the inner diameter of the rotating slot 409, and the inner diameter of the second rotating connecting ball sleeve 803 is consistent with the outer diameter of the first rotating adjustment ball 408, ensuring that after the first rotating connecting ball sleeve 802 is connected to the rotating slot 409 at the bottom of the connecting sleeve rod 401, and after the second rotating connecting ball sleeve 803 is connected to the first rotating adjustment ball 408, the first rotating connecting ball sleeve 802 can rotate with damping inside the rotating slot 409, and the first rotating adjustment ball 408 can rotate with damping inside the second rotating connecting ball sleeve 803.

The first buffer gap 8022 between the first elastic arc-shaped petals 8021 and the first elastic arc-shaped petals 8021 enables the adjacent first elastic arc-shaped petals 8021 to bend toward the axis of the middle connecting rod 801 to ensure that the first rotating connecting ball sleeve 802 smoothly enters the inner side of the rotating slot 409.

[0037] The second rotating connecting ball sleeve 803 includes a plurality of second elastic arc-shaped petals 8031 ​​rotating in a circular array around the axis of the middle connecting rod 801, and a second buffer gap 8032 is provided between two adjacent second elastic arc-shaped petals 8031. The top end of the second elastic arc-shaped petal 8031 ​​is fixedly connected to the first rotating connecting ball sleeve 802. The first buffer gap 8022 between the second elastic arc-shaped petals 8031 ​​and the second elastic arc-shaped petals 8031 ​​enables the adjacent second elastic arc-shaped petals 8031 ​​to bend toward the outside of the middle connecting rod 801 to ensure that the first rotating connecting ball sleeve 802 is smoothly clamped on the outside of the first rotating adjustment ball 408.

[0038] like Figure 4 and Figure 5As shown, electromagnetic adsorption support frames 5 are provided on both sides of the center ring 1, and the electromagnetic adsorption support frames 5 include two rotation adjustment rods 501. The outer surface of the center ring 1 is provided with a rotation groove 6. The bottom surface and the upper surface of the center ring 1 are penetrated by two symmetrically distributed guide grooves 7. One end of the rotation adjustment rod 501 is rotatably connected to the inner side of the rotation groove 6. The end of the rotation adjustment rod 501 located on the inner side of the rotation groove 6 is penetrated and fixed with an adjustment short rod 512. The top and bottom ends of the adjustment short rod 512 are slidably inserted in On the inner side of the guide groove 7, the top and bottom ends of the adjusting short rod 512 are both threadedly installed with fastening screws 513, and the end of the rotating adjusting rod 501 and the center ring 1 are connected by the adjusting short rod 512, and the rotating adjusting rod 501 can rotate around the axis of the center ring 1 to change the angle between the two rotating adjusting rods 501, and the fastening screws 513 fix the position of the adjusting short rod 512 and the center ring 1 to ensure that after the angle of the rotating adjusting rod 501 is adjusted, the position of the end of the rotating adjusting rod 501 cannot be moved.

[0039] The end of the rotating adjustment rod 501 away from the center ring 1 is fixed with an end connecting block 502, and the bottom end of the end connecting block 502 is installed with a guide connecting rod 503, and the bottom end of the guide connecting rod 503 is slidably installed with a second sliding connecting rod 505, and the outer side of the bottom end of the guide connecting rod 503 is connected with a second anti-slip screw 504 through a thread, and the end of the second anti-slip screw 504 is in contact with the outer surface of the second sliding connecting rod 505, and the bottom end of the second sliding connecting rod 505 is fixed with an adsorption electromagnet 506, which is connected and fixed to the front panel of the car by using the adsorption electromagnet 506 to ensure that when the front panel of the car is offset, there will be no relative movement between the front panel connecting plate and the front panel of the car.

[0040] A powered coil 507 is wound around the outside of the adsorption electromagnet 506, and a connecting wire 508 is fixed between the top ends of the two powered coils 507. A first wire 509 is fixed to the bottom end of one of the powered coils 507, and a second wire 511 is fixed to the bottom end of the other powered coil 507. A battery 510 is fixed between the first wire 509 and the second wire 511. The battery 510, the first wire 509, the second wire 511 and the connecting wire 508 ensure that current flows inside the two powered coils 507, thereby ensuring that the adsorption electromagnet 506 has additional magnetism and is magnetically adsorbed and fixed to the front panel of the car, thereby ensuring the stability and safety of the device during use.

[0041] Working principle: First, according to the welding position of the automobile front wall connecting plate on the automobile front wall panel and the surface shape of the automobile front wall panel, four suitable points are selected on the automobile front wall panel surface for magnetic adsorption and fixation of the four adsorption electromagnets 506. After the four suitable points are selected, the fastening screw 513 on the top of the adjusting short rod 512 is rotated, and a gap appears between the end of the Shudie fastening screw 513 and the surface of the center ring 1. At this time, the end of the sliding and rotating adjusting rod 501 changes the position of the rotating adjusting rod 501 inside the rotating groove 6 until the position of the adsorption electromagnet 506 reaches just above the selected point, and the fastening screw 513 is rotated in the opposite direction so that the fastening screw 513 contacts the surface of the center ring 1 and locks the adjusting short rod 512 and the end of the rotating adjusting rod 501.

[0042] Then, the second sliding connecting rod 505 is slid and pulled out from the bottom end of the guide connecting rod 503, so that the bottom of the attraction electromagnet 506 is completely in contact with the surface of the car's front panel, and then the second anti-slip screw 504 is tightened so that the end of the second anti-slip screw 504 enters the inside of the guide connecting rod 503 and is pressed against the outer surface of the second sliding connecting rod 505. At this time, the second sliding connecting rod 505 cannot move along the axial direction of the guide connecting rod 503. At this time, the battery 510 transmits current to the inside of the first wire 509. The current forms a current loop through the first wire 509, the energized coil 507, the connecting wire 508, the energized coil 507 and the second wire 511. When the current passes through the inside of the energized coil 507, the attraction electromagnet 506 is magnetically attached and fixed to the magnetic wire of the car's front panel, and the device is fixed.

[0043] Next, the dash panel connecting plate is fitted to the dash panel of the automobile, and the length of the first sliding link 411 is adjusted so that the first sliding link 411 slides out from the bottom of the rotating connecting rod 402, so that the positioning U-shaped plate 405 is close to the top of the dash panel connecting plate of the automobile. Then, according to the top shape and tilt angle of the dash panel connecting plate of the automobile, the first anti-slip screw 403 is tightened so that the first sliding link 411 cannot slide, and the first rotating adjustment ball 408 and the second rotating adjustment ball 410 are rotated to adjust the actual position and angle of the positioning U-shaped plate 405 until the two welding fixing clips 406 are located on both sides of the top of the dash panel connecting plate of the automobile.

[0044] Tighten the clamping screws 407 on both sides of the positioning U-shaped plate 405 so that the two welding fixing clips 406 clamp and fix the top of the automobile front wall connecting plate. Repeat the operation process of the welding clamping mechanism 4 to connect the three positioning U-shaped plates 405 to the automobile front wall connecting plate. Use the three welding clamping mechanisms 4 to clamp and fix the automobile front wall connecting plate to ensure that the bottom of the automobile front wall connecting plate is completely fitted with the automobile front wall plate. Finally, use an automatic or semi-automatic arc or plasma arc welding machine to weld the automobile front wall connecting plate to the automobile front wall plate.
