The first fixed frame 1 is fixedly mounted with a transverse guide rail fixed frame 2, and the guide rail fixed frame 2 is mounted with a first screw guide rail 3 and a second screw guide rail 4 arranged in parallel, the first screw guide rail 3 is connected to the first fixed assembly 5, the first clamping assembly 7 is fixedly mounted on the first fixed assembly 5, the second screw guide rail 4 is connected to the second fixed assembly 6, the second clamping assembly 8 is fixedly mounted on the second fixed assembly 6, and the first clamping assembly 7 and the second clamping assembly 8 are both fixedly connected with special-shaped clamping claws 9.

[0022] The movement of the first fixed component 5 and the second fixed component 6 are controlled respectively by the first screw guide rail 3 and the second screw guide rail 4, so that the distance between the first fixed component 5 and the second fixed component 6 changes. The distance between the first clamping component 7 and the second clamping component 8 is controlled by controlling the distance between the first fixed component 5 and the second fixed component 6, so that the wire harness clamped by the first clamping component 7 and the second clamping component 8 is bent due to the change in the distance between the first clamping component 7 and the second clamping component 8, thereby realizing the bending and U-forming of the wire harness.

[0023] The first screw guide rail 3 and the second screw guide rail 4 have the same structure, and both include a servo motor 31, a motor fixing plate 32, a rotating fixing seat 33, a threaded rod 34 and a guide rail 35. A connecting hole is fixedly opened on the rotating fixing seat 33, and a rotating bearing 36 is fixedly installed in the connecting hole. The two ends of the threaded rod 34 are respectively fixedly connected to the inner annular surface of the rotating bearing 36 of the rotating fixing seat 33, and one end of the threaded rod 34 passes through the rotating bearing 36 and is fixedly connected to the output end of the servo motor 31. The servo motor 31 is fixedly installed on the motor fixing plate 32. The guide rail 35 is arranged on one side of the threaded rod 34, and the guide rail 35 and the threaded rod 34 are parallel to each other.

[0024] The threaded rod 34 is driven to rotate by the servo motor 31 , thereby driving the first fixed component 5 and the second fixed component 6 to translate through the rotation of the threaded rod 34 , and the guide rail 35 is used to guide the translation of the first fixed component 5 and the second fixed component 6 .

[0025] The first fixed component 5 and the second fixed component 6 have the same structure, and both include a fixed mounting plate 51, a threaded sleeve 52, a slide block 53 and a lifting cylinder 54. A threaded sleeve 52 is fixedly mounted on one side of the fixed mounting plate 51, and a threaded through hole is fixedly opened on the threaded sleeve 52. The threaded sleeve 52 is sleeved on the threaded rod 34 through the threaded through hole, and the transmission is achieved by engaging the internal thread of the threaded through hole with the external thread of the threaded rod 34. Slide blocks 53 are provided on both sides of the threaded sleeve 52. The slide block 53 is fixedly mounted on the fixed mounting plate 51, and the slide block 53 is slidably connected to the guide rail 35. A lifting cylinder 54 is fixedly mounted on the other side of the fixed mounting plate 51. The lifting cylinder 54 is used for lifting and lowering the first clamping component 7 and the second clamping component 8.

[0026] The first material clamping assembly 7 and the second material clamping assembly 8 have the same structure, and the first material clamping assembly 7 and the second material clamping assembly 8 are symmetrically arranged. The first material clamping assembly 7 and the second material clamping assembly 8 both include a rotating motor 71, a clamping fixing seat 72 and a clamping cylinder 73. The rotating motor 71 is fixedly installed on the upper end of the clamping fixing seat 72, and the output end of the rotating motor 71 is fixedly connected to the clamping cylinder 73 through the clamping fixing seat 72.

[0027] The clamping cylinder 73 drives the clamping claws to clamp the wire harness, and the rotating motor 71 cooperates with the adjustment of the distance between the first clamping component 7 and the second clamping component 8 to achieve the bending and U-forming of the wire harness.

[0028] A limiting assembly 61 is provided between the first fixing assembly 5 and the second fixing assembly 6 . The limiting assembly 61 includes a limiting male head and a limiting female head. The limiting male head and the limiting female head are fixedly mounted on the first fixing assembly 5 and the second fixing assembly 6 , respectively.

[0029] The limiting assembly 61 is used to prevent the first material clamping assembly 7 from colliding with the second material clamping assembly 8 and the moving parts of the two assemblies, thereby improving operation safety.

[0030] The specific operation steps are as follows: after the wire harness is loaded to the designated area, the two servo motors 31 are controlled to rotate through the program, thereby controlling the two clamping components to reach the designated position and clamp the wire harness. After clamping, the servo motor 31 rotates to move the wire harness clamp to the designated position. During this period, the distance between the first clamping component 7 and the second clamping component 8 becomes smaller, and the rotating motor 71 drives the clamp to rotate to achieve the bending and U-forming of the wire harness. After the product reaches the designated position, the wire harness has been U-formed, and the lifting cylinder 54 controls the wire harness to reach the designated height, and releases the wire harness to place the wire harness in the clamping station.
