Description

Technical Field

[0001] This utility model relates to the field of wire stripping machine technology, and more specifically, it relates to a wire stripping machine for wire harness preparation. Background Technology

[0002] In the existing technology, the design of many wire harness preparation stripping machines faces some obvious challenges, especially the inconvenience and shortcomings in the process of fixing and loosening the wires. Specifically, the wire fixing is not effective enough, which leads to instability and inefficiency in the stripping process, while the wire loosening is often a troublesome step, affecting production efficiency and ease of operation.

[0003] In traditional wire stripping machines, the cable fixing device is usually quite simple, using mechanical clamping or spring force to maintain cable stability. Due to the significant differences in cable type and outer diameter, traditional fixing methods may not provide precise fixation for cables of different sizes. If the cable is not clamped evenly during the fixing process, the stripping blade may not cut the outer insulation material evenly, affecting the stripping quality. During high-intensity operation, the cable may shift or loosen, causing the equipment to be unable to continuously and stably perform the stripping work. For example, if the cable experiences even a slight displacement during stripping, it may lead to asymmetrical cutting by the blade or incomplete stripping, potentially damaging the cable in severe cases.

[0004] In traditional wire stripping machines, the cable loosening mechanism is usually quite rudimentary. Most equipment uses mechanical or hydraulic devices to loosen the clamping device, but this process often requires manual operation or relatively complex mechanical adjustments. Most existing equipment involves complicated operating steps when loosening cables, which may require manual adjustment of the clamping device or adjustment of the cable loosening degree through hydraulic cylinders. This increases the difficulty and time cost for operators. Utility Model Content

[0031] Please see Figures 1-5A wire stripping machine for wire harness preparation includes a frame 1, a clamping and stripping mechanism, a cable fixing mechanism, and a fixing auxiliary mechanism. The clamping and stripping mechanism includes a hydraulic push cylinder 2, a clamping liquid cylinder 3, a clamping frame 4, spring-loaded blades 5, and spring guide wheels 6. The hydraulic push cylinder 2 is horizontally mounted on the top end of the frame 1, the clamping liquid cylinder 3 is mounted on one end of the hydraulic push cylinder 2, and the clamping frame 4 is mounted on one end of the clamping liquid cylinder 3. The clamping frames 4 are arranged opposite each other, and the cable to be stripped is clamped between the clamping frames 4. Multiple sets of spring-loaded blades 5 and springs... The guide wheel 6 is mounted on the clamping frame 4. The cable fixing mechanism includes a clamping sleeve 7, an inclined rail 8, an inclined block 9, a linkage frame 10, a spring nail frame 11, and an embedded nail 12. The clamping sleeve 7 is fixedly mounted on the side of the frame 1. The inclined rail 8 is set on the inner wall of the clamping tube. The inclined block 9 is inclinedly slidably mounted on the inclined rail 8. The spring nail frame 11 is mounted on the side wall of the inclined block 9. The spring nail frame 11 can clamp and fix the cable to be stripped. The linkage frame 10 is directionally slidably set on the outer and inner walls of the clamping tube.

[0032] In this embodiment, when the equipment is started, the hydraulic push cylinder 2 begins to push laterally, and the clamping cylinder 3 is responsible for pushing the clamping frame 4 inward to clamp the cable to be stripped between the clamping frames 4, ensuring that the cable is firmly clamped and the cable to be stripped is firmly clamped to ensure the stability of the cable during the stripping process. The hydraulic push cylinder 2 pushes the spring clip 5 and spring guide wheel 6 installed on the clamping frame 4 to start cutting and guiding the outer insulation material of the cable. The spring clip 5 can adapt to different cable outer diameters through the action of the spring, providing a precise and uniform stripping effect. The clamping sleeve 7 is fixedly installed on the side of the frame 1 to provide a reference position to fix the cable. Its function is to ensure that the cable remains stable during the fixing and stripping process. The inclined rail 8 is set on the inner wall of the clamping tube, and the inclined sliding block 9 is inclined and slidably installed on the inclined rail 8. The movement of the tilt block 9 helps to adjust the relative position of the cable, ensuring the correct positioning of the cable between the clamping sleeve 7 and the clamping frame 4. The spring nail frame 11 is installed on the side wall of the tilt block 9, and the embedded nail 12 can firmly clamp the cable to be stripped. Through the spring force, the spring nail frame 11 can apply appropriate clamping force to the cable, ensuring that the cable will not loosen or slip during the entire stripping process.

[0033] The fixed auxiliary mechanism includes a limiting ring 13, a rotating block 14, a rotating ring 15, a pressure groove 16, a fixing frame 17, and a pressure spring 18. The limiting ring 13 is rotatably mounted on the outer wall of the clamping sleeve 7. The rotating block 14 is mounted on the bottom end of the limiting ring 13. The inner wall of the limiting ring 13 is threadedly connected to the linkage frame 10 on the outer wall. The rotating ring 15 is mounted on the rotating block 14. Multiple pressure grooves 16 are set on the rotating ring 15. The fixing frame 17 is fixedly mounted on the outer wall of the clamping tube. The pressure spring 18 is mounted on the fixing frame 17. The pressure spring 18 can extend into the pressure groove 16 step by step, so that the rotating ring 15, the rotating block 14, and the limiting ring 13 rotate stably on the outer wall of the clamping sleeve 7.

[0034] In this embodiment, the limiting ring 13 is installed on the outer wall of the clamping sleeve 7 and connected to the rotating block 14. The function of the limiting ring 13 is to limit the movement range of the rotating block 14 and ensure that the rotating block 14 will not leave the normal working area during operation. The rotating ring 15 is installed on the rotating block 14, and the pressure groove 16 is set on the rotating ring 15. The compression spring 18 can lock the rotating ring 15 in a stable position through compression, so that the rotating ring 15 remains stable during operation. The compression spring 18 is installed on the fixed frame 17. As the compression spring 18 extends into the pressure groove 16 step by step, the rotation of the rotating ring 15, the rotating block 14 and the limiting ring 13 is further stabilized. This design ensures that the clamping sleeve 7 can rotate stably during operation and that the cable is not accidentally loosened during stripping.

[0035] Please see Figures 1-5 As a supplementary embodiment of a wire harness preparation wire stripping machine with a clamping stripping mechanism, a cable fixing mechanism, and a fixing auxiliary mechanism: A connecting frame 19 is installed at one end of the hydraulic push cylinder 2, and a clamping hydraulic cylinder 3 is installed at the bottom end of the connecting frame 19. A guide frame 20 is installed inside the frame 1, and the guide frame 20 can guide the cable to be stripped between the clamping frames 4. A connecting plate 21 is installed at the bottom end of the clamping sleeve 7, and the connecting plate 21 is fixedly installed on one side of the frame 1. A connecting block 22 is installed at the bottom end of the inclined block 9, and the linkage frame 10 at the inner wall end is slidably connected to the connecting block 22. A waste bin 23 is installed at the bottom end of the frame 1, and the waste bin 23 collects the waste material of the cable to be stripped. Support legs 24 are installed around the bottom end of the frame 1.

[0036] More specifically, first, the cable to be stripped is placed between clamping frame 4 and clamping sleeve 7. Clamping sleeve 7 fixes the cable in the appropriate position, ensuring the cable is within clamping frame 4. Hydraulic push cylinder 2 is activated, pushing clamping cylinder 3 to tighten clamping frame 4 and fix the cable. Clamping frame 4 guides the cable through spring clips 5 and spring guide wheels 6. Spring clips 5 begin cutting the outer insulation of the cable, ensuring uniform and undamaged stripping. During the stripping process, the cable remains fixed under the control of clamping sleeve 7 and clamping frame 4, preventing displacement. During stripping, the stripped waste is collected through waste bin 23 at the bottom of frame 1 to prevent waste from scattering and ensure a clean operating environment. After stripping, clamping frame 4 and clamping sleeve 7 are released, and the cable is released. The stripped cable can then be further processed.

[0037] In summary, during the use or operation of the overall equipment: when the clamping and stripping mechanism is in operation, it is responsible for fixing the cable to be stripped and removing the outer insulation layer. When the equipment is started, the hydraulic push cylinder 2 begins to push laterally, and the clamping cylinder 3 is responsible for pushing the clamping frame 4 inward, clamping the cable to be stripped between the clamping frames 4 to ensure that the cable is firmly clamped and to ensure the stability of the cable during the stripping process. The hydraulic push cylinder 2 pushes the spring clip 5 and spring guide wheel 6 installed on the clamping frame 4 to start cutting and guiding the outer insulation material of the cable. The spring clip 5 can adapt to different cable outer diameters through the action of the spring, providing a precise and uniform stripping effect.

[0038] When the cable fixing mechanism is in operation, it is used to fix the cable to be stripped, ensuring its stable position and preventing displacement during the stripping process. The clamping sleeve 7 is fixedly installed on the side of the frame 1, providing a reference position to fix the cable. Its function is to ensure that the cable remains stable during fixing and stripping. The inclined rail 8 is set on the inner wall of the clamping tube, and the inclined sliding block 9 is inclined and slidably installed on the inclined rail 8. The movement of the inclined sliding block 9 can help adjust the relative position of the cable, ensuring the correct positioning of the cable between the clamping sleeve 7 and the clamping frame 4. The spring nail frame 11 is installed on the side wall of the inclined sliding block 9. The embedded nail 12 can firmly clamp the cable to be stripped. Through the spring force, the spring nail frame 11 can apply an appropriate clamping force to the cable, ensuring that the cable will not loosen or slip during the entire stripping process.

[0039] When the auxiliary mechanism needs to be fixed during operation, the limiting ring 13 is installed on the outer wall of the clamping sleeve 7 and connected to the rotating block 14. The function of the limiting ring 13 is to limit the movement range of the rotating block 14 and ensure that the rotating block 14 will not leave the normal working area during operation. The rotating ring 15 is installed on the rotating block 14, and the pressure groove 16 is set on the rotating ring 15. The compression spring 18 can lock the rotating ring 15 in a stable position through compression, so that the rotating ring 15 remains stable during operation. The compression spring 18 is installed on the fixing frame 17. As the compression spring 18 extends into the pressure groove 16 step by step, the rotation of the rotating ring 15, the rotating block 14 and the limiting ring 13 is further stabilized. This design ensures that the clamping sleeve 7 can rotate stably during operation and that the cable is not accidentally loosened during stripping.

[0040] First, the cable to be stripped is placed between clamping frame 4 and clamping sleeve 7. Clamping sleeve 7 secures the cable in the appropriate position, ensuring the cable is within the clamping frame 4. Hydraulic push cylinder 2 is activated, pushing clamping cylinder 3 to tighten and secure the clamping frame 4. Clamping frame 4 guides the cable via spring-loaded blades 5 and spring-loaded guide wheels 6. Spring-loaded blades 5 begin cutting the outer insulation of the cable, ensuring uniform and undamaged stripping. During the stripping process, the cable remains fixed under the control of clamping sleeve 7 and clamping frame 4, preventing displacement. Waste material is collected in the waste bin 23 at the bottom of frame 1 during stripping, preventing spillage and ensuring a clean operating environment. After stripping, clamping frame 4 and clamping sleeve 7 are released, freeing the cable. The stripped cable can then be further processed.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
