The control handle is hinged to the bottom of the bending work plate. A fixed plate is fixedly connected to the bending work plate, and a track body is provided on the fixed plate; A connector, which is mounted on a fixed plate; A reset unit is disposed between the bending work plate and the control handle, and the reset unit is used to control the control handle to reset. The straightening unit includes an adjusting block slidably connected within a connector, a second spring body fixedly connected between the adjusting block and the inner wall of the connector, and a T-shaped control handle fixedly connected to the adjusting block. The straightening unit is used to straighten the wire harness.

[0006] Preferably, the reset unit includes: The first fixing block is fixedly connected to the bottom of the control handle; The second fixing block is fixedly connected to the bottom of the bending work plate; The first spring body is fixedly connected between the first fixed block and the second fixed block.

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] This utility model discloses a pre-bending clamp for automotive wiring harnesses, according to the attached... Figure 1 As shown, it includes: The bending work plate 1 serves as the core support platform of the fixture, supporting all functional modules and providing an operating reference surface.

[0018] The fixed plate 3 is fixedly connected to the bending working plate 1. The fixed plate 3 is provided with a track body 31, which fixes the straightening unit 6 and guides its linear movement to ensure the stability of the straightening process.

[0019] Connector 4 is mounted on the fixing plate 3; A wire harness stop block 11 and a length ruler 12 are installed on the bending work plate 1. An angle ruler 13 is fixedly connected to the side wall of the bending work plate 1. A support leg 14 is fixedly connected to the bottom of the bending work plate 1.

[0020] Multiple limit clamps 32 are installed on the fixing plate 3. The limit clamps 32 are used to limit the wire harness.

[0021] According to the appendix Figure 2 As shown, further, the bending block 2 is slidably connected to the bending work plate 1, and a control handle 21 is fixedly connected to the bottom of the bending block 2. The control handle 21 is hinged to the bottom of the bending work plate 1. The reset unit 5 is disposed between the bending work plate 1 and the control handle 21. The reset unit 5 is used to control the control handle 21 to reset. Reset unit 5 includes: The first fixing block 51 is fixedly connected to the bottom of the control handle 21; The second fixing block 53 is fixedly connected to the bottom of the bending working plate 1; The first spring body 52 is fixedly connected between the first fixed block 51 and the second fixed block 53. When the control handle 21 is rotated, the first spring body 52 is stretched to store energy; after release, the first spring body 52 returns to its original shape, thereby driving the control handle 21 to reset.

[0022] According to the appendix Figure 3 As shown, the straightening unit 6 further includes an adjusting block 61 slidably connected within the connector 4. A second spring body 62 is fixedly connected between the adjusting block 61 and the inner wall of the connector 4. A T-shaped control handle 63 is fixedly connected to the adjusting block 61. The straightening unit 6 is used to straighten the wire harness. The straightening unit 6 pre-straightens the wire harness to eliminate bending stress and improve bending accuracy.

[0023] The bottom of the connector 4 is fixedly connected to the track block 41, and the track block 41 is slidably connected inside the track body 31.

[0024] The bottom of the adjusting block 61 is provided with an arc-shaped groove 611, which corresponds to the shape of the wire harness. When the wire harness is stuck in the arc-shaped groove 611, the adjusting block 61 is driven by the sliding connector 4 to achieve the purpose of quickly adjusting the wire harness.

[0025] Working principle: The automotive wiring harness pre-bending fixture uses the bending work plate 1 as a base. The straightening unit 6 is constructed by the fixed plate 3 and the track body 31. The connecting piece 4 and the track block 41 realize the lateral positioning of the straightening module. During operation, one end of the wiring harness is placed against the wiring harness abutment block 11, and the other end is passed through the limit clamp 32 and placed into the arc-shaped slot 611 of the straightening unit 6. The T-shaped control handle 63 is pushed to complete the straightening. Then, the control handle 21 is rotated to drive the bending block 2 to slide along the work plate. The bending parameters are controlled with the angle ruler 13 and the length ruler 12. After release, the first spring body 52 of the reset unit 5 drives the control handle 21 to automatically reset, ready for the next operation.

[0026] The pre-bending fixture for this automotive wiring harness adopts a structure in which a straightening unit 6 is set inside the connector 4. When there are many small bends on the wiring harness, the adjusting block 61 inside the straightening unit 6 holds the wiring harness and slides on the fixing plate 3. This allows the entire wiring harness to be straightened before pre-bending. Then, by rotating the bending block 2, the wiring harness is pre-bent at a specific angle, which effectively ensures the aesthetics and practicality of the wiring harness after pre-bending, while reducing the cost of wiring harness pre-bending.
