Description

Technical Field

[0001] The utility model belongs to the technical field of automobile wire harness production, and in particular relates to a wire harness or terminal supporting roller structure. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminal (connector) made of copper material, which is crimped with the wires and cables, and then the insulator is plastic-pressed on the outside or a metal shell is added, etc., to form a component that connects the circuit. In the early stage of the wiring harness manufacturing, the cables need to be cut into preset lengths or terminalized by machines such as wire unloading machines and wire crimping machines. However, the conventional operation places the cable roll or terminal roll on the ground, which is extremely easy to be contaminated with dirt and is easy to be messy or stuck. Now, a special placement rack is created for the cable roll or terminal roll to avoid this problem, but the placement rack takes up too much space, which will affect other passers-by or require a larger placement space, resulting in excessively high cost of use.

[0003] In the prior art, the patent document with publication number CN218491152U discloses a wire harness winding device with a cleaning structure, including a bracket, a transmission motor is fixedly connected to the front of the bracket, a winding wheel is movably connected to the inside of the bracket, and the winding wheel is transmission-connected to the transmission motor, an extension plate is fixedly connected to the right side of the bracket, a swing rod is movably connected to the top of the extension plate through a pin, and the inner side of the swing rod and the inner side of the extension plate are both movably connected to a support roller through a pin, and a cleaning structure is arranged on the surface of the support roller, and the cleaning structure includes a sponge sleeve sleeved on the surface of the support roller. The above technical scheme realizes the cleaning of the wire harness, but this is to eliminate pollution interference in the process of manufacturing and winding the cable. In the production of automotive wire harnesses, the cable is used. The use of such a cable will increase the cost investment, and the cable model required by the automobile manufacturer is uncontrollable, and it is impossible to perform secondary winding processing on the cable roll. Therefore, the cable placement position can only be reasonably planned to better avoid contamination of the cable during use. Utility Model Content

A handle 4 is also arranged in the middle of the inclined support handle 2, and a control handle 5 is installed at the end of the handle 4 for controlling the rotation angle of the inclined support handle 2 on the mounting base 1. The mounting base 1 is mounted on the lower surface of the workbench of a machine such as a line-cutting machine through a bolt structure, so the end of the inclined support handle 2 is rotatably mounted on the lower surface of the mounting base 1, and the inclined support handle 2 is arranged tilted downward, but the mounting base 1 can also be arranged on the upper surface of the workbench of a machine such as a line-cutting machine through other connection methods such as welding, and the inclined support handle 2 is arranged tilted upward, but the upper surface of the workbench is generally occupied by other machines, which is not convenient for operation. Therefore, the inclined support handle 2 is tilted downward for easier operation and has a larger activity space. The control handle 5 can be used to control the inclined support handle 2 and the support roller structure 3 to turn to different positions and directions.

[0024] The support roller structure 3 is provided with a transverse support rod 31, which is installed on the inclined support handle 2. A rotating roller 32 and two limit seats 33 are sleeved on the transverse support rod 31. The two limit seats 33 are respectively located at both ends of the rotating roller 32. The rotating roller 32 rotates with the transverse support rod 31, and the limit seats 33 are clamped on the transverse support rod 31.

[0025] The limit seat 33 has a chuck portion and a flange portion. The flange portion is arranged in the middle of one side of the chuck portion, and the other side of the chuck portion contacts the end face of the rotating roller 32. A threaded hole is opened on the flange portion, and a fastening screw 34 is installed in the threaded hole. The fastening screw 34 passes through the threaded hole and is clamped on the transverse support rod 31.

[0026] The middle part of the cable roll or terminal roll is sleeved on the rotating roller 32, and its two end surfaces are limited by two limit seats 33, so that there will be no mess. It only rotates with the production. The structure is simple and is additionally installed on the production workbench, so that the cable roll or terminal roll on the rotating roller 32 is suspended in the air, which can prevent the cable roll or terminal roll from being contaminated by dirt, so that the wiring harness manufacturing quality is better, and the extended inclined support handle 2 and the support roller structure 3 can adapt to the production at different angles according to the rotation angle, and can be easily retracted under the production workbench when not in use, without occupying additional space, and is more convenient to operate, safe and convenient to use, and the two limit seats 33 and the rotating roller 32 are movably sleeved on the transverse support rod 31, and various types of cable rolls or terminal rolls can be adapted by adjusting the distance between the two limit seats 33 and replacing the rotating rollers 32 with different outer diameters and lengths, thereby improving work efficiency.

[0027] The above-mentioned inclined support handle 2 is in the shape of an elongated strip, and three mounting holes 21 are opened on the inclined support handle 2 for mounting the transverse support rod 31, so as to facilitate replacement of different height positions of the transverse support rod 31 to adapt to different operators. More mounting holes 21 can be provided, but it is generally not necessary. The handle 4 is arranged perpendicular to the inclined support handle 2, and the control handle 5 is arranged horizontally for easy operation.

[0028] A rotating shaft seat 11 is arranged in the middle of the mounting seat 1, and a rotating shaft sleeve 22 is arranged at the end of the oblique support handle 2. The rotating shaft sleeve 22 is sleeved on the rotating shaft seat 11, and two spring steel balls 12 are installed inside the rotating shaft seat 11. It can also be four spring steel balls 12 or other numbers. As long as there is space for installation, the more the better. The two spring steel balls 12 are symmetrically arranged, and the structure is more stable. A rolling ring groove 23 is opened on the inner surface of the rotating shaft sleeve 22. The spring steel ball 12 extends out of the outer surface of the rotating shaft seat 11 and rolls with the rolling ring groove 23. A compression spring is provided on the other side of the spring steel ball so that the spring steel ball is always compressed. There is a rolling ring groove 23, and six limiting spherical grooves 24 on the rolling ring groove 23. One spring steel ball 12 corresponds to three limiting spherical grooves 24 respectively. The three limiting spherical grooves 24 correspond to the wire harness production transmission position, the terminal transmission position and the storage position respectively. The spring steel ball cooperates with the rolling ring groove 23 or the limiting spherical groove 24 to limit the rotation position, and the limiting spherical groove 24 has a temporary locking effect. By controlling the handle 5 to bend it forcefully, the spring steel ball can be disengaged from the limiting spherical groove 24, that is, disengaged from the locked position state.
