Description

Technical Field

[0001] This utility model relates to the field of wire harness cutting technology, specifically to a clamping and length-cutting tool for automotive wire harnesses. Background Technology

[0002] The automotive wiring harness clamping and length-cutting fixture is a device used to accurately measure and cut the length of automotive wiring harnesses to ensure accuracy and consistency during the production process. The wiring harness is pulled out from the harness reel and placed into the threading holes. A pneumatic clamp holds the wire ends of the harness. The clamp moves a specified distance, and the blade cuts the harness. The clamp then releases, and the harness falls onto the worktable. The clamp moves back to the wire ends, clamps them again, moves a specified distance, and cuts once more.

[0003] When a wire harness is placed in a threaded hole, a clamping device holds the wire end and moves it to a specified distance before a blade cuts it. After cutting, the wire end may momentarily loosen, potentially causing it to detach from the threaded hole. Therefore, a clamping and length-cutting fixture for automotive wire harnesses is needed to solve this problem. Utility Model Content

The worktable 10 is fixed to the lower end of the support platform 11, the upper end of the hydraulic rod 12 is fixed to the upper end of the support platform 11, the knife holder 13 is fixed to the lower end of the hydraulic rod 12 and is located inside the support platform 11, and the wire threading hole 17 is opened at the lower end of the first limiting plate 16 and communicates with the opening 20.

[0028] The workbench 10 and support table 11 provide support. The hydraulic rod 12 provides a power source to control the up and down movement of the tool holder 13 and the blade 14. The tool holder 13 is used to fix the blade 14, and the blade 14 is used to cut the wire harness. The first fixing plate 15 is used to support the wire harness. The first limiting plate 16 is used to limit the movement. The wire hole 17 is used to separate the wire harness into individual strands.

[0029] The first pressing assembly includes an opening 20, a sealing plate 21, a spring column 25, a movable plate 26, a second fixed plate 27, a connecting shaft 28, and a roller 29. The opening 20 is located in the middle of the first limiting plate 16. The sealing plate 21 is fixed to the upper end of the first limiting plate 16. The spring column 25 is fixed to the lower end of the sealing plate 21. The movable plate 26 is fixed to the lower end of the spring column 25.

The threaded hole 210 is opened in the middle of the sealing plate 21, the screw 22 is screwed into the threaded hole 210, and the lower end is rotatably connected to the middle of the upper end of the first support plate 24.

[0031] The first pressing assembly also includes a first limiting hole 211 and a limiting rod 23. The first limiting hole 211 is opened on the sealing plate 21 and is located on both sides of the threaded hole 210. The limiting rod 23 is inserted into the first limiting hole 211 and its lower end is fixed in the first support plate 24.

[0032] The first support plate 24 and the roller 29 are movably connected inside the opening 20 and the threading hole 17;

[0033] The opening 20 is used to install the roller 29, the sealing plate 21 provides support, the threaded hole 210 and the screw 22 provide adjustment, the first limiting hole 211 and the limiting rod 23 provide limiting to prevent the first support plate 24 from shifting position when it moves, the first support plate 24 provides support, the spring column 25 has a telescopic function, the movable plate 26 provides support, and the second fixed plate 27 is used to fix the connecting shaft 28. The connecting shaft 28 facilitates the rotation of the roller 29, and the roller 29 can reduce the resistance when the wire harness moves.

[0034] Working principle:

[0035] The wire harness is inserted sequentially into the threaded hole 17. Rotating the screw 22 in the threaded hole 210 moves the first support plate 24 within the opening 20. Simultaneously, the limiting rod 23 moves within the first limiting hole 211. The movement of the first support plate 24 also moves the movable plate 26 at the lower end of the spring column 25. Meanwhile, the connecting shaft 28 and roller 29 inside the second fixed plate 27 move downwards, pressing against the wire harness. Pulling the wire harness causes the roller 29 to rotate.

[0036] This step prevents the wire harness from coming loose in the wire hole 17 after the wire harness is cut.

[0037] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The second pressing assembly includes a second support plate 30, a coil spring 31 and a pressure plate 34. The second support plate 30 is fixed on both sides of the upper end of the tool holder 13, the upper end of the coil spring 31 is fixed on the lower end of the second support plate 30, and the pressure plate 34 is fixed on the lower end of the coil spring 31.

[0039] The second pressing assembly also includes a second limiting plate 32 and a second limiting hole 33. The second limiting plate 32 is fixed on both sides of the lower end of the tool holder 13, the second limiting hole 33 is opened in the middle of the second limiting plate 32, and the pressure plate 34 is movably connected in the second limiting hole 33.

[0040] The second support plate 30 provides support, the round spring 31 has a telescopic function, the second limiting plate 32 and the second limiting hole 33 provide limiting function, and the pressure plate 34 provides pressing function.

[0041] Working principle:

[0042] The movable end of the hydraulic rod 12 moves, causing the tool holder 13 and the blade 14 to move downwards, and at the same time, causing the second support plate 30 to move downwards. When the pressure plate 34 presses on the wire harness, as the blade 14 moves downwards, the pressure plate 34 is blocked by the wire harness. The second support plate 30 continues to move downwards, causing the coil spring 31 to be compressed. The pressure plate 34 moves along the second limiting hole 33 on the second limiting plate 32. After the cutting is completed, the tool holder 13 and the blade 14 move upwards, and the coil spring 31 extends, so that the pressure plate 34 is still pressing on the wire harness until the blade 14 moves to the uppermost position, at which point the pressure plate 34 is disengaged from the wire harness.

[0043] This step can press and hold both ends of the wire harness at the cut point to prevent the cut point from shifting.
