Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a stripping tool for multi-core cable processing. Background Technique

[0002] The stripping tool plays a crucial role in multi-core cable processing, and its main functions are as follows: 1) Improve cutting accuracy: Due to the complexity of its structure, multi-core cables have high requirements for cutting accuracy. Through precise mechanical design and positioning devices, the stripping tool can ensure that each wire core reaches extremely high dimensional accuracy during cutting, avoiding the decline or failure of cable performance caused by dimensional deviation. 2) Simplify the stripping process: For multi-core cables, stripping is a cumbersome and error-prone process. The stripping tool integrates a stripping mechanism, which can automatically or semi-automatically complete the stripping of the cable outer sheath while protecting the internal wire cores from damage. This not only improves work efficiency but also reduces the quality problems and safety hazards that may be brought by manual stripping. 3) Improve production efficiency: Compared with traditional manual cutting and stripping methods, the stripping tool can achieve automated or semi-automated operations, significantly improving the processing speed. 4) Ensure processing quality: By optimizing the cutting and stripping processes, the stripping tool can ensure that the cut surface and stripping opening of each wire core are flat and smooth, reducing defects such as burrs and scratches caused by improper manual operation. This not only improves the appearance quality of the cable but also ensures the stability of its electrical and mechanical properties. 5) Adapt to different specifications of cables: The stripping tool usually has adjustability and can adapt to the processing requirements of multi-core cables with different specifications and materials. This flexibility enables the tool to play an important role in different production scenarios, improving the adaptability and flexibility of the production line.

[0003] It is found that the traditional stripping tool for multi-core cable processing has deficiencies in use. For the processing of multi-core cables, a gas stripping machine is generally used to cut and strip each core wire to the required length. For example, for a three-core cable, three gas stripping machines are required, and multiple workers are needed during the gas stripping process, resulting in low efficiency and high manufacturing costs of the product. Therefore, it is necessary to optimize and improve the traditional stripping tool for multi-core cable processing. Content of the Utility Model

The nut of the first ball screw 4 is installed on the first slider 6, and the first slider 6 can slide along the first horizontal guide rail 5. A first mounting plate 7 is installed on the first slider 6. A clamping cylinder 8 and an ear seat 10 are installed on the first mounting plate 7. Several groups of jaws 11 distributed in parallel are rotatably supported in the ear seat 10.

[0031] In this embodiment, the stripping knife assembly includes a second motor 12, a second ball screw 13, a second horizontal guide rail 14, a second slider 15, a second mounting plate 16, a stripping knife motor 17, a double-thread ball screw 18, a vertical guide rail 19, a third slider 20, a stripping knife mounting seat 21, and a stripping knife 22. The output shaft of the second motor 12 is connected to the screw of the second ball screw 13 through a coupling. The nut of the second ball screw 13 is installed on the second slider 15, and the second slider 15 can slide along the second horizontal guide rail 14. A second mounting plate 16 is installed on the second slider 15, and a stripping knife motor 17 is installed on the second mounting plate 16. The output shaft of the stripping knife motor 17 is connected to the double-thread ball screw 18 through a coupling. There are two nuts on the double-thread ball screw 18 that can displace relative to each other. The nuts are installed on the corresponding third sliders 20, and the third sliders 20 can slide along the vertical guide rail 19. The third sliders 20 are installed with stripping knives 22 through the stripping knife mounting seats 21.

[0032] In this embodiment, the first motor 2 in the clamping assembly and the second motor 12 in the stripping knife assembly are fixed on the back side of the mounting frame 1. The first ball screw 4 and the first horizontal guide rail 5 in the clamping assembly are arranged in parallel on the front side of the mounting frame.

[0033] In this embodiment, the number of clamping cylinders 8 and pressing blocks 9 is equal to the number of groups of clamping jaws 11.

[0034] In this embodiment, a guide groove for facilitating the linear displacement of the pressing block 9 is provided in the first mounting plate 7.

[0035] In this embodiment, each group of clamping jaws 11 is composed of two oppositely arranged clamping jaws.

One end of the clamping jaw 11 close to the pressing block 9 is used as the contact end, and the other end of the clamping jaw 11 is used as the clamping end. Anti-slip clamping ridges are provided on the inner side of the clamping jaw 11 at the clamping end.

[0037] In this embodiment, a sharp corner is provided on the side of the pressing block 9 close to the clamping jaw 11. When the pressing block 9 displaces towards the clamping jaw 11, the pressing block 9 can drive the contact end of the clamping jaw 11 to flip outwards from the inside, and the clamping ends of the two clamping jaws 11 flip inwards accordingly to clamp the cable together.

[0039] A specific application of this embodiment is as follows: After the core wire of the cable reaches the processing position, the clamping cylinder 8 in the clamping assembly drives the pressure block 9 to slide outwards, and the corresponding group of clamping jaws 11 close to clamp the corresponding core wire. Then, the first horizontal displacement system composed of the first motor 2, the belt transmission member 3, the first ball screw 4, the first horizontal guide rail 5, and the first slider 6 drives the first mounting plate 7 and the clamping jaws 11 thereon to translate. During the translation process, the clamping jaws 11 are loosened in sequence from long to short (more waste wire will be cut off for the one with a longer pulled-out distance, and the remaining will be shorter. The loosening position can be set to control the size and meet the product requirements). The stripping knife displacement system composed of the stripping knife motor 17, the left and right hand ball screw 18, the vertical guide rail 19, and the third slider 20 drives the stripping knife mounting seat 21 and the stripping knife 22 thereon to approach and close to cut off the excess core wire, and then open; the second horizontal displacement system composed of the second motor 12, the second ball screw 13, the second horizontal guide rail 14, and the second slider 15 drives the second mounting plate 16 and the stripping knife 22 thereon to move forward as a whole (the distance is based on the requirements of riveting terminals). The stripping knife 22 closes to a suitable size according to the core wire diameter, and the second mounting plate 16 and the stripping knife 22 thereon move backward as a whole to strip the insulation layer of the core wire; after the above actions are completed, the translation fixture on the equipment takes away the wire, and each part returns to the initial position to wait for the next processing.

[0040] Control the retraction of the clamping cylinder 8, that is, the loosening time of the clamping jaws 11 according to the length requirement, pull out different lengths of multiple core wires, and cooperate with the stripping knife 22 to process long and short wires according to the requirements. The stripping knife 22 is controlled by the stripping knife motor and the left and right hand ball screw, and the opening and closing size of the knife edge can be set arbitrarily. The translation of the entire stripping knife assembly is also completed by the cooperation of the motor and the screw, and the length of stripping the insulation layer can be controlled arbitrarily, so as to cooperate with the next step of riveting the terminal. The illustrated structure is for three-core wires and can be compatible with two-core wires. At the same time, if there are more core wires, it can be achieved by increasing the number of clamping jaws 11 and customizing the stripping knife 22.
