Description

Technical Field

[0001] The utility model relates to the technical field of automobile wire harness production, in particular to a wire twisting device for automobile wire harness production. Background Art

[0002] An automobile wire harness is the network main body of an automobile circuit. Without a wire harness, there would be no automobile circuit. A wire harness refers to a component formed by crimping contact terminals made of copper materials to electric wires and cables, and then molding an insulator outside or adding a metal shell, etc., and bundling the wire harness to form a connected circuit. The wire harness industry chain includes electric wires and cables, connectors, processing equipment, wire harness manufacturing and downstream application industries. The wire harness is widely used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc. The body wire harness connects the entire body and generally has an H shape. Currently, when producing an automobile wire harness, it is often necessary to twist the core wire of the wire harness. However, when fixing one end of the wire harness with the existing wire twisting device, it often requires manual fixing by workers, resulting in low production efficiency. Moreover, the existing wire twisting device is not convenient to adjust the wire twisting processing distance according to the lengths of different wire harnesses, bringing inconvenience to the use of workers and having low practicability.

[0003] For example, in the utility model with the application number 20212200230.9, a wire twisting device for automobile wire harness production is disclosed. The utility model provides a wire twisting device for automobile wire harness production. By opening rotating shaft grooves on both sides of the conveying support plate, the two driving sleeves are rotatably sleeved, thereby driving the conveying chain plate to rotate. A plurality of connecting plates are fixedly installed on the outer wall of the conveying chain plate, thereby fixedly connecting the two wire harness clamping plates. Secondly, clamping rubber pads are fixedly installed on one side of each wire harness clamping plate to sequentially convey a plurality of automobile wire harnesses, and then quickly and conveniently twist a plurality of automobile wire harnesses.

[0004] The current situation similar to the above application still has deficiencies:

[0005] This kind of wire twisting device for automobile wire harness production can adjust and adapt the processing position according to wire harnesses of different lengths. However, during the wire twisting process of the wire harness, there will be frictional losses during the continuous rotation of the driving components, reducing the transmission efficiency. During long-term use, it is necessary to lubricate manually regularly, which is not only inconvenient to operate but also affects the normal working efficiency.

[0006] Therefore, a wire twisting device for automobile wire harness production is designed to optimize the above problems. Content of the Utility Model

[0007] The main purpose of the utility model is to provide a wire twisting device for automobile wire harness production to solve the related technical problems mentioned in the above background art.

[0008] The object of the utility model can be achieved by adopting the following technical solutions:

An adsorption cotton is fixed at the bottom of the dropper. The output shaft of the motor is fixed with a rotating shaft. A cam is fixed outside the rotating shaft, and the cam is movably connected with the T-shaped rod. One end of the rotating shaft is fixed with a first gear.

Sliding rods are slidably installed on both sides of the U-shaped plate, and one ends of the sliding rods all penetrate and extend into the inside of the U-shaped plate. A sleeve is sleeved on one end of each sliding rod. Second springs are sleeved outside the sliding rods, and two ends of each second spring are respectively fixed to one side of the sleeve and the inner side wall of the U-shaped plate. The bottom ends of the sliding rods are all rotatably installed with limiting rollers.

[0011] Preferably: A fixing plate is installed at the bottom of the fixed table. Fixing rods all penetrate through the fixing plate. Third springs are sleeved outside the fixing rods. Bases are fixed at the bottom ends of the fixing rods. Buffer blocks are fixed at the bottom of the fixing plate and the top of the bases respectively.

[0017] Through the combined use of a sliding seat, a U-shaped plate, a sliding rod, a collar, a second spring and a limiting roller, after one end of multiple clusters of wire harnesses is fixed on the first clamping member, the other end of each cluster of wire harnesses is sequentially placed into the inside of the U-shaped plate. Under the elastic force of the second spring, the limiting roller limits the outside of the wire harness, and then the sliding seat is pushed to the right, so that the U-shaped plate pulls the wire harness to the second clamping member, and then each cluster of wire harnesses is fixed by the second clamping member, thus facilitating the wire twisting work of the staff;

Under the elastic force of the third spring, the vibration frequency is slowed down and part of the vibration is offset. At the same time, the buffer block further improves the damping effect, thereby improving the stability of the wire twisting device for actual automobile production.

[0025] Embodiment 1

[0026] As Figures 1-4 shown, this embodiment provides a wire twisting device for automobile wire harness production, including a fixed table 1. A fixed frame 2 is installed at the top of one end of the fixed table 1. A motor 3 is installed inside the fixed frame 2. A storage bin 6 is installed on the inner top wall of the fixed table 1. A T-shaped rod 7 is slidably installed at the bottom of the storage bin 6. A first spring 8 is sleeved on the outer side of the T-shaped rod 7. A dropper 9 is fixed at the bottom of one end of the storage bin 6, and the dropper 9 is communicated with the storage bin 6. An adsorption cotton 10 is fixed at the bottom of the dropper 9. The output shaft of the motor 3 is fixed with a rotating shaft 4. A cam 5 is fixed on the outer side of the rotating shaft 4, and the cam 5 is movably connected with the T-shaped rod 7. One end of the rotating shaft 4 is fixed with a first gear 11. Inside the fixed frame 2 and on the left and right sides of the first gear 11, second gears 12 are respectively rotatably installed, and the second gears 12 are meshed with the first gear 11. Clamping members one 13 are installed on one side of the second gears 12 and the first gear 11. A clamping member two 20 is slidably installed on the fixed table 1. A sliding seat 14 is slidably installed on the top of the fixed table 1. A U-shaped plate 15 is fixed on the top of the sliding seat 14. Slide bars 16 are slidably installed on both sides of the U-shaped plate 15, and one ends of the slide bars 16 penetrate and extend into the U-shaped plate 15. A collar 17 is sleeved on one end of the slide bars 16. Second springs 18 are sleeved on the outer sides of the slide bars 16, and both ends of the second springs 18 are respectively fixed to one side of the collar 17 and the inner side wall of the U-shaped plate 15. Limiting rollers 19 are rotatably installed at the bottom ends of the slide bars 16.

[0027] Put one end of the wire harness into the clamping member one 13 to fix it, and put the other end of the wire harness into the clamping member two 20 to fix it. Start the motor 3 to drive the rotating shaft 4 and the cam 5 to rotate, and then drive the clamping member one 13 and the wire harness to rotate simultaneously through the second gear 12 to twist the wire harness. At the same time, the rotating shaft 4 drives the cam 5 to rotate, so that the cam 5 pushes the T-shaped rod 7 upward, and the lubricating liquid inside the storage bin 6 enters the dropper 9 and wets the adsorption cotton 10 to lubricate the outer side of the rotating first gear 11.
