The chassis suspension bracket welding refers to the process of welding the chassis suspension bracket to the vehicle chassis during the automobile manufacturing process. The quality of chassis suspension bracket welding is directly related to the structure and performance of the automobile chassis, so precise control and quality assurance of the welding process are essential. Reasonable welding process and equipment selection, strict quality control can ensure the strength, sealing and durability of the welded joint, and improve the quality and reliability of the whole vehicle.

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] Reference Figure 1-Figure 3, a chassis suspension bracket welding tool, comprising two relatively arranged moving mechanisms, the moving mechanism comprising a driving frame 1, the driving frame 1 is composed of a top plate, a base and four limit columns, the top plate and the base are respectively fixed at the upper and lower ends of the four limit columns, a first motor 2 is fixedly installed on the upper end of the base, the output end of the first motor 2 is coaxially fixedly connected with a vertically arranged first threaded rod 3, the upper end of the first threaded rod 3 is rotatably connected to the lower end of the top plate, a moving sleeve 4 is threadedly connected to the first threaded rod 3, a first fixed block 5 is fixedly sleeved on the moving sleeve 4, the four limit columns of the driving frame 1 are distributed in a rectangular shape, and a "]"-shaped lifting frame 6 is fixedly connected to the side of the first fixed block 5 close to the four limit columns, and the lifting frame 6 is slidably connected to the outside of the four limit columns, when the two first motors 2 simultaneously drive each first threaded rod 3 to rotate in one direction, the moving sleeve 4 threadedly connected to the first threaded rod 3 will drive the first fixed block 5 to move up and down, so that the lifting frame 6 fixedly connected to the first fixed block 5 slides up and down along the track formed by the four limit columns in the driving frame 1. A worm 8 is connected to the front and rear inner walls of the lifting frame 6 for rotation. A second motor 7 for driving the worm 8 to rotate is fixedly installed at the front end of the lifting frame 6, and a rotating shaft 10 is connected to the inner walls of the opposite sides of the two lifting frames 6 for rotation. A worm wheel 9 is fixedly sleeved on the rotating shaft 10, and the upper end of the worm wheel 9 is meshed with the corresponding worm 8. A fixing mechanism is provided between the two rotating shafts 10, and the fixing mechanism includes a welding frame 11 fixedly connected between the two rotating shafts 10. When the two second motors 7 drive each worm 8 to rotate in one direction at the same time, the two worms 8 will drive the worm wheels 9 meshed therewith and the rotating shaft 10 fixedly sleeved on the worm wheel 9 to rotate in the same direction, so that the welding frame 11 fixedly connected between the two rotating shafts 10 rotates. Because the worm wheel 9 and the worm 8 have self-locking properties, when the worm 8 stops rotating, the worm wheel 9 and the rotating shaft 10 fixedly sleeved thereon cannot rotate, so that the welding frame 11 fixedly connected between the two rotating shafts 10 is locked at the adjusted angle.
[0021] The front and rear inner walls of the welding frame 11 are both provided with movable openings 21 transversely, and two second fixing plates 23 symmetrically distributed on the left and right are slidably connected between the two movable openings 21. The two second fixing plates 23 are longitudinally penetrated through the two movable openings 21, and the front and rear ends of each second fixing plate 23 are fixedly connected to the limiting frame 15. The ends of the four limiting frames 15 away from the welding frame 11 are fixedly connected to the second fixing blocks 13, and the two second fixing blocks 13 at the front end are threadedly connected to the two bidirectional threaded rods 14. The rear end of the welding frame 11 is fixedly connected to the sliding rod 22 arranged transversely, and the sliding rod 22 slides through the two second fixing blocks 13 at the rear side. There is a protrusion at the front end of the welding frame 11, and the bidirectional threaded rod 14 penetrates and is rotatably connected with it, so as to separate the threads of the bidirectional threaded rod 14 in two directions. The bottom of the two limit frames 15 located at the front end of the welding frame 11 are fixedly installed with a fourth motor 19, and the output end of the fourth motor 19 is coaxially fixedly connected with the second threaded rod 16, and the other end of the second threaded rod 16 is rotatably connected to the inner top wall of the limit frame 15. The upper and lower inner walls of the two limit frames 15 located at the rear are commonly fixedly connected with a limit slide bar 18, and the two limit slide bars 18 and the second threaded rod 16 are sleeved with a third fixed block 17, and the first fixed plate 20 is commonly fixedly connected between the two third fixed blocks 17 corresponding to the front and rear. The front end of the welding frame 11 is fixedly installed with a third motor 12 that drives the bidirectional threaded rod 14 to rotate. When the two fourth motors 19 simultaneously drive the second threaded rods 16 to rotate in one direction, the first fixing plate 20 threadedly connected to the second threaded rod 16 will move up and down; when the third motor 12 drives the bidirectional threaded rod 14 to rotate in one direction, the two second fixing blocks 13 threadedly connected to the bidirectional threaded rod 14 move toward the middle or both sides at the same time, thereby driving the limiting frame 15, the first fixing plate 20, the second fixing plate 23, the second threaded rod 16, and the third fixing block 17 associated with the second fixing block 13 to move.
[0022] When using the utility model, the first motor 2 drives the first threaded rod 3 to rotate so as to lower the height of the welding frame 11, and the chassis to be welded is placed on the welding frame 11. The third motor 12 drives the bidirectional threaded rod 14 to rotate so as to move the two first fixing plates 20 to the middle to a suitable position, and then the fourth motor 19 drives the second threaded rod 16 to rotate so as to lower the two first fixing plates 20 to a suitable height, thereby fixing the bottom plate on the welding frame 11, and then the first motor 2 drives the first threaded rod 3 to rotate in the opposite direction so as to raise the welding frame 11 to a suitable height. When it is necessary to rotate the welding frame 11 and the chassis fixed thereon, it is only necessary to drive the worm 8 to rotate through the second motor 7, thereby driving the worm wheel 9 to rotate the welding frame 11 fixedly connected between the two rotating shafts 10. When the required angle is adjusted, the second motor 7 is stopped. Due to the self-locking property of the worm gear, the welding frame 11 and the chassis fixed thereon will be locked at the adjusted angle, and the position will be kept stable, thereby realizing multi-directional and multi-angle welding.
[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
