[0002] The frame is a frame structure that spans the front and rear axles of the car, commonly known as the beam, and is the base of the car. It is generally composed of two longitudinal beams and several cross beams, and is supported on the wheels through the suspension device, the front axle, and the rear axle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels.

When the slider 705 on the far side moves toward the boss 404, the slider 705 pushes the assembly of the slide 708 and the arched sleeve 706 or the assembly of the slide 708 and the plug 707 outward, and the springs 709 are squeezed and contracted. When the outermost slider 705 is away from the boss 404, under the elastic action of spring three 709, the assembly of the slide 708 and the arch sleeve 706, and the assembly of the slide 708 and the plug plate 707 move toward the middle of the arch plate 401, keeping the upper side of the end of the slide groove 403 covered.

[0043] When in use, first, two longitudinal beams are placed on the top of two sets of brackets 200, and the motor 1 302 drives the rotating shaft 301 to rotate, and the meshing action of the bevel gear 1 312, the bevel gear 2 313 and the bevel gear 3 314 is coordinated to make the fixed plate 308 and the rotating plate 310 rotate in opposite directions, so that the horizontal plate 1 309 and the horizontal plate 2 311 are deflected in opposite directions and deflected to the top of the bracket 200;

[0044] During the rotation of the rotating shaft 301, the gear 1 303 rotates synchronously, driving the assembly of the two sets of L-shaped clamping plates 304 and the rack plate 306 to slide back to back along the guide groove 305, so that the two sets of L-shaped clamping plates 304 and the two sets of fixed clamping blocks 307 clamp and fix the two sets of longitudinal beams; then, by screwing the threaded rod 1 316, the pressing plate 317 is abutted against the top of the longitudinal beam, so that the pressing plate 317 cooperates with the bracket 200 to clamp and fix the longitudinal beam from the longitudinal direction;

[0045] Then, multiple beams are placed on the top of the arched plate 401, and each beam is placed inside each group of sliders 705; the second motor 504 drives the second threaded rod 503 to rotate, driving the two groups of sliders 502 to move toward each other along the second slide groove 501, thereby driving the two groups of support rods of the scissor fork 505 to deflect, and driving the assembly of the arched plate 401 and the extension plate 402 to move upward;

[0046] During this process, the roller 604 rolls against the guide plate 605, and when passing the inclined portion of the guide plate 605, it drives the two sets of sliding plates 601 to move toward the arch plate 401, drives the two sets of push plates 608 to clamp at the ends of the beam, and pushes the beam to move on the top of the arch plate 401, so that the middle of the beam is aligned with the middle of the arch plate 401;

[0047] Then, the motor 3 704 drives the gear 3 703 to rotate, driving the gear 2 702 and the threaded rod 3 701 to rotate, so that each group of sliders 705 moves toward each other along the slide groove 1 403, clamping the beam and fixing the beam in the left and right directions;

[0048] Afterwards, the lifting drive 500 continues to drive the assembly of the arch plate 401 and the extension plate 402 to move upward, and the assembly of the push plate 608 and the top plate 610 is blocked at the bottom of the longitudinal beam. The cross beam continues to move upward with the arch plate 401 and is inserted between the two longitudinal beams, and then cooperates with the blocking column 406 to block the longitudinal beam from the outside to ensure that the cross beam and the longitudinal beam fit closely to facilitate subsequent welding.

[0049] After welding is completed, the motor 3 704 drives the gear 3 703 to rotate in the opposite direction, which can drive each group of sliders 705 to move in opposite directions, loosening the clamping effect on the crossbeam; the motor 2 504 then drives the threaded rod 2 503 to rotate in the opposite direction, driving the two groups of slide seats 502 to move in opposite directions along the slide groove 2 501, and the two support rods of the scissor fork 505 deflect in the opposite direction, driving the assembly of the arch plate 401 and the extension plate 402 to move downward, so that the end clamp 600 and the crossbeam clamp 700 are separated from the crossbeam and the longitudinal beam;

[0050] Then, the threaded rod 1 316 is screwed in the opposite direction to move the pressure plate 317 upward and separate from the longitudinal beam; the motor 1 302 drives the rotating shaft 301 to rotate in the opposite direction to deflect the transverse plate 1 309 and the transverse plate 2 311 and move away from the longitudinal beam; at the same time, the gear 1 303 drives the two sets of L-shaped clamping plates 304 to move toward each other to release the clamping effect on the longitudinal beam. At this time, the welded transverse beam and longitudinal beam can be removed from the bracket 200.
