The limit plate 305 is released on one side of the hinged frame 306. The limit plate 305 is an L-shaped plate structure. The top of the limit plate 305 is fixedly connected to the bottom of the welder 5. The inner wall of the hinged frame 306 is rotatably connected to the rotating shaft B307. The outer wall of the rotating shaft B307 is rotatably connected to the hinge block B308. The hinged frame 306 is used to push the rotating shaft B307 and the hinge block B308 through the hinge. When in use, two wire harnesses to be welded are placed between two long rollers B318 on the bottom plate 317, the middle parts of the two wire harnesses are rotated and twisted into a bundle in advance, and then the electric lifter 1 is started to control the welder 5 to be lifted to a specified position, and the welding head 6 under the welder 5 is used to complete the welding of the two wire harnesses; Example 2: Please refer to Figure 1-11 On the basis of the first embodiment, the present invention provides a technical solution: a pressing block 309 is fixedly connected to the bottom of the hinge block B308, the bottom of the pressing block 309 contacts a bottom plate 317, a pad 316 is fixedly connected to the bottom of the bottom plate 317, an electric slider is arranged at the bottom of the pad 316, and the electric slider is fixedly connected to the top of the welding table 2.
[0019] The bottom of the pressing block 309 is slidably connected to the surface of the bottom plate 317 , and an arc groove 310 is provided on the inner wall of the pressing block 309 , and a long roller A311 is rotatably connected to the inner wall of the arc groove 310 .
[0020] The inner wall of the long roller A311 is rotatably connected with a roller 312, one side of the pressing block 309 is fixedly connected with a fixed plate 313, the top of the fixed plate 313 is fixedly connected with a telescopic rod 314, the top of the telescopic rod 314 is slidably connected with a sliding bar 315, and the top of the sliding bar 315 is fixedly connected to the bottom of the welder 5; When the welder 5 descends to weld the wire harness through the welding head 6, the hinge block A301, the rotating shaft A302 and the hinge frame 306 are driven to descend, and the hinge frame 306 drives the hinge block B308 and the pressing block 309 to descend synchronously through the rotating shaft B307. When the pressing block 309 descends, the long rollers A311 inside the two arc grooves 310 are used to press the wire harness and complete the stable welding of the wire harness. At the same time, as the welder 5 continues to descend, the pressing block 309 will be pushed against the bottom plate 317 below, and as the two hinge frames 306 are turned outward, the pressing block 309 will be pushed against the bottom plate 317 below. The angle of the "eight" shape is hinged to open and close on both sides, so that the pressing blocks 309 on the left and right sides press the wire harness and push it to both sides, tightening and straightening the two wire harnesses, thereby fully straightening the part where the two wire harnesses are intertwined to avoid bending. As the welder 5 continues to descend, the welding head 6 below is used to complete the welding work at the intertwined part of the wire harnesses, and then the two wire harnesses are automatically tightened while the wire harnesses are clamped and welded stably, thereby improving the accuracy of wire harness welding, and also completing the welding after the wire harnesses are straightened, thereby avoiding the problem of welding position deviation caused by welding bending and warping; When the two pressing blocks 309 use the long roller A311 to press against the wire harness below and straighten it to both sides, the roller 312 on the long roller A311 will roll on the wire harness, thereby avoiding the friction problem caused by the long roller A311 moving radially on the wire harness, so as to reduce the problem of the wire harness being pulled too much and causing the middle interweaving part to be loosened. While the wire harness is straightened and tightened by a certain pulling force, the stability of the two wire harnesses being interwoven together is also effectively guaranteed; Example 3: Please refer to Figure 1-14 On the basis of the first and second embodiments, the present invention provides a technical solution: the top of the bottom plate 317 is rotatably connected with a long roller B318, the outer wall of the pressing block 309 is provided with a leveling mechanism 4, the leveling mechanism 4 includes a slide plate 401, and the outer wall of the slide plate 401 is slidably connected with the bottom of the pressing block 309.
[0021] A baffle 402 is fixedly connected to one side of the slide plate 401 , a telescopic rod 403 is fixedly connected to one side of the baffle 402 , the other end of the telescopic rod 403 is fixedly connected to one side of the pressing block 309 , and a spring 405 is fixedly connected to one side of the pressing block 309 .
[0022] One end of the spring 405 is fixedly connected to one side of the baffle 402 . A threaded groove 404 is provided on the outer wall of the long roller A311 . The threaded groove 404 is provided on the outer wall of the long roller A311 between the pressing block 309 and the baffle 402 .
[0023] There are two long rollers A311 on the inner wall of the pressing block 309, the thread directions of the two long rollers A311 are opposite to each other, and the thread lead angle of the thread groove 404 is greater than fifty-five degrees; When the pressing block 309 presses against the bottom plate 317 below, the slide plate 401 below the pressing block 309 will replace the pressing block 309 to press against the bottom plate 317, so that the friction between the slide plate 401 and the bottom plate 317 presses against each other, and then the pressing block 309 is pushed downward by the hinge frame 306 and continues to slide in the directions of both sides, and the bottom of the pressing block 309 slides on the top of the slide plate 401, and the bottom of the slide plate 401 remains stationary with the bottom plate 317 through the friction force, so when the pressing block 309 slides, it will move toward the baffle 402. The long roller A311 in the arc groove 310 is moved along with the inner wall of the arc groove 310, and the long roller A311 is rotatably connected to the middle of the inner wall of the arc groove 310, so that one end of the long roller A311 is threadedly rotated on the inner wall of the baffle 402 through the thread groove 404, and the thread lead angle of the thread groove 404 is greater than forty-five degrees, so that the friction force of vertical movement and rotation is very low, and the spiral sliding and rotation in the baffle 402 can be performed, so that the long roller A311 is carried The long roller A311 rotates together with the two long rollers B318, and the long roller A311 drives the roller 312 to rotate in a circle by its axial rotation direction. The roller 312 generates friction with the surface of the wire harness through the axial rotation direction of the long roller A311, thereby driving the wire harness to rotate together. The rotation directions of the two long rollers A311 are consistent, so that the wire harness between the two long rollers A311 and the two long rollers B318 is driven to rotate, and the long roller A311 under the left pressure block 309 is rotated. The rotation direction of 311 is opposite to the rotation direction of the long roller A311 under the right pressure block 309, so that the left and right wire harnesses can rotate synchronously in opposite directions, and are straightened and straightened synchronously with the rotation, so that the wire harnesses are further rotated and interwoven again in the direction of rotation while being straightened, thereby effectively avoiding the loosening of the interwoven parts in the process of straightening and tightening the two wire harnesses, ensuring the welding accuracy and improving the stability of the wire harness welding; Once the two wire harnesses are pushed outward by the friction force and pulled apart when the two pressing blocks 309 move outward, it also indicates that the wire harnesses are interwoven and loose, and they are pulled apart by themselves, thereby realizing the self-checking function before the wire harnesses are welded; After welding is completed, when the welder 5 is lifted, the pressure block 309 is rebounded to its original position by the elastic force of the spring 405, and at this time, the pressure block 309 under the hinge block B308 and the slide plate 401, the baffle plate 402 and the structure thereon are centered at the center of gravity, so that the pressure block 309 maintains a stable horizontal state, and the angle of the hinge frame 306 is reset and stabilized at an "eight" shape because the fixed plate 304 and the rotating shaft A302 are subjected to the elastic force of the spring 303, so that everything is reset and waits for the next lifting and welding work.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
