[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 3 , the utility model provides a technical solution:

[0020] A positioning fixture for wire harness production includes a base 1, a support frame 2 symmetrically installed above the base 1, and an upper fixture 3 and a lower fixture 4 installed between the support frames 2. A slide groove 5 is provided on one side of the support frame 2, and a moving mechanism for adjusting and driving the distance between the upper fixture 3 and the lower fixture 4 is installed inside the slide groove 5. A plurality of arc grooves are provided on one side of the upper fixture 3 and the lower fixture 4, and an arc clamp 6 is slidably installed in the arc grooves.

[0021] When in use, the wiring harness is placed in sequence above the arc-shaped clamp 6 located on the lower clamp 4, and then the distance between the upper clamp 3 and the lower clamp 4 is adjusted by adjusting the moving mechanism, so that the wiring harness can be clamped and fixed between the two arc-shaped clamps 6, thereby achieving the purpose of fixing wiring harnesses of different sizes. The structure is simple, the operation is convenient, and the production cost is reduced.

[0022] The moving mechanism includes a bidirectional threaded rod 7 rotatably mounted inside the slide slot 5 and a slider 8 sleeved on both ends of the bidirectional threaded rod 7 and connected to the bidirectional threaded rod 7 by spiral transmission. Both ends of the upper clamp 3 and the lower clamp 4 are connected to the slider 8 respectively.

[0023] A threaded hole is provided at one end of the support frame 2, one end of the bidirectional threaded rod 7 passes through the threaded hole and extends into the slide groove, and a knob is installed at the other end. The bidirectional threaded rod 7 is driven to rotate by manually turning the knob in forward and reverse directions, so that the slider 8 moves toward or relative to the outside of the bidirectional threaded rod 7. When relative movement occurs, the arc-shaped clamping plate 6 is driven to move to clamp the wiring harness. When opposite movement occurs, the arc-shaped clamping plate 6 is driven to leave the wiring harness and release its fixation.

[0024] A plurality of chambers 9 are provided inside the upper clamp 3 and the lower clamp 4 and on one side of the arc groove, a through hole is provided between the chamber 9 and the arc groove, a T-bar 10 is provided for internal sliding connection, one end of the T-bar 10 passes through the through hole and extends into the arc groove to be connected with the arc clamp 6, and a spring 11 is provided between the other end and the inner wall of the chamber 9. When the two arc clamps 6 clamp the wire harness, the arc clamp 6 will squeeze the wire harness, and the wire harness will also squeeze the arc clamp 6 at the same time. Under the action of the elastic force of the T-bar 10 and the spring 11, the stability of clamping is improved.

[0025] A rubber wear-resistant pad is installed on one side of the arc-shaped clamping plate 6 to further enhance the firmness of the clamping of the wire harness.
