[0032] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0033] like Figure 1 As shown, a wire harness stripping device of this application includes a stripping cutter 1, a guide wheel assembly 2, a feed roller 3, a limiting plate 4, and a support frame 5. The stripping cutter 1 is used to cut the insulation layer of the wire harness, exposing the internal conductor. The stripping cutter 1 is rotatably mounted on the support frame 5 to achieve effective cutting of the wire harness during the stripping process. It can also move relative to the wire harness through rotational motion, ensuring smooth cutting. This mounting method also helps adjust the stripping depth to accommodate wire harnesses of different specifications. The guide wheel assembly 2 is fixedly mounted on the support frame 5 and located on the inlet side of the stripping cutter 1. This assembly guides the wire harness into the stripping area, ensuring its stability before entering the cutter. The circumferential surface of the guide wheel 21 is provided with a V-shaped groove 31 to adapt to wire harnesses with different cross-sectional shapes, preventing the wire harness from shifting or falling during feeding. Furthermore, a limiting guide groove 22 is fixed on the axial end face of the guide wheel 21 (see details). Figure 3 The feed roller 3, coaxially mounted on the support frame 5 and opposite to the guide roller assembly 21, restricts the circumferential rotation of the wire harness, preventing torsional deformation during passage and thus improving the quality of subsequent processing. The feed roller 3 is rotatably mounted on the support frame 5 and is positioned opposite to the guide roller assembly 2, forming a channel for the wire harness to pass through. This feed roller 3 is connected to the drive motor via a mechanical transmission structure, driving the wire harness forward in a preset direction to ensure continuous and uniform stripping operation. Simultaneously, the distance between the roller and the guide roller assembly 2 can be adjusted by the adjusting screw 23 to accommodate wire harnesses of different diameters, thereby enhancing the applicability of the equipment. The limiting plate 4 is rigidly connected to the support frame 5 and is located on the exit side of the guide roller assembly 2. Its main function is to constrain the radial displacement of the wire harness before entering the stripping cutter 1, preventing lateral offset or jumping during operation, thus ensuring the positional stability of the wire harness during stripping. The support frame 5 is used to support and fix all components, maintaining structural stability throughout operation. Made of metal, it possesses high strength and rigidity, and its compact overall design facilitates equipment installation and maintenance.

[0034] The guide wheel 21 in the guide wheel assembly 2 uses a V-shaped groove 31 on its circumferential surface to accommodate the wire harness, ensuring that the wire harness can pass stably along a predetermined path instead of swinging or bending randomly. Simultaneously, the axially fixed limiting guide groove 22 effectively prevents circumferential rotation of the wire harness during operation, reducing the impact of wire harness torsion. Combined with the guiding function at the front end of the guide wheel assembly 2 and the stable conveying by the feed roller 3, the direction and posture of the wire harness can be effectively controlled, avoiding problems such as equipment jamming, damage, or incomplete stripping caused by wire harness twisting and knotting. Furthermore, the auxiliary positioning of the limiting plate 4 further restricts the lateral displacement of the wire harness, enabling the entire stripping device to maintain high operational accuracy and stability during continuous operation, thus solving the technical problem of preventing wire harness twisting and knotting.

[0035] like Figure 1 and Figure 3 As shown, in one embodiment, the guide wheel 21 of the wire harness stripping device of this application has a V-shaped groove 31 on its circumferential surface with anti-slip texture 24 inside. The anti-slip texture 24 is used to enhance the friction between the guide wheel 21 and the wire harness, improve the stability of the wire harness during feeding, and avoid slippage or twisting due to insufficient friction. At the same time, the guide wheel assembly 2 also includes an auxiliary limiting wheel 25, which is rotatably mounted on the side of the guide wheel 21 and coaxially arranged with the limiting guide groove 22. It is used to apply additional radial constraint to the wire harness to prevent it from deviating during transportation. The guide wheel 21 and the limiting guide groove 22 are fixedly connected to the same end face to ensure that the wire harness maintains a stable posture before entering the stripping cutter 1.

[0036] Specifically, the circumferential surface of the guide wheel 21 is machined to form a V-shaped groove 31, and a textured structure is set inside the groove to increase the contact area and friction coefficient. The auxiliary limiting wheel 25 is mounted on the side bracket of the guide wheel 21 by bearings, so that it can rotate freely with the movement of the wire harness, while maintaining a concentric relationship with the limiting guide groove 22, thereby achieving synchronous limiting and guiding of the wire harness.

[0037] like Figure 3 As shown, in one embodiment, the limiting guide groove 22 of the wire harness stripping device of this application includes a plurality of parallel guide grooves 26, each guide groove 26 having a different size to accommodate wire harnesses of different diameters. By setting guide grooves 26 of different sizes, the displacement of the wire harness in the rotational direction can be effectively limited, thereby ensuring that the wire harness maintains a stable posture during processing. The guide grooves 26 are distributed along the axial end face of the guide wheel 21 and are coaxially mounted with the guide wheel 21, allowing the wire harness to move along the guide path of the guide grooves 26 when passing through the guide wheel 21. The design of multiple guide grooves 26 improves the compatibility of the device with wire harnesses of different specifications, and enhances the practicality and flexibility of the equipment.

[0038] Specifically, the limiting guide groove 22 is composed of multiple parallel groove structures. The width and depth of each groove are set according to the preset wire harness specifications. The grooves are embedded in the axial end face of the guide wheel 21 and are rigidly connected to the guide wheel 21 by bolts or other fixing methods to ensure structural stability and positioning accuracy. The position of the guide groove 26 matches the wire harness channel, so that the wire harness can be guided into the corresponding guide groove 26 when passing through the guide wheel 21, thereby achieving effective control of the circumferential rotation of the wire harness.

[0039] like Figure 5 As shown, in one embodiment, the stripping blade 1 of the wire harness stripping device of this application includes a guide ring 6, which is rotatably sleeved on the outside of the blade to guide the wire harness to maintain a straight feed during cutting and prevent twisting. The guide ring 6 is located in the area where the stripping blade 1 contacts the wire harness and forms a concentric structure with it to ensure that the wire harness can be effectively positioned before entering the cutting area. The guide ring 6 is installed near the front end of the blade and is axially supported and fixed to the outside of the stripping blade 1, ensuring that it can rotate with the blade while guiding the wire harness to prevent deviation or knotting during movement. The guide ring 6 has a simple structure and is easy to manufacture, possessing good wear resistance and guiding stability.

[0040] Specifically, the guide ring 6 is fixed to the outside of the stripping tool 1 via a threaded connection. It is made of metal to improve durability, and the inside of the ring has a groove that matches the shape of the wire harness, so that it applies radial pressure to the wire harness during rotation, thus playing a role in stable guidance. At the same time, a lubrication structure is provided between the guide ring 6 and the tool to ensure that it can rotate flexibly without affecting the overall operating efficiency.

[0041] like Figure 5 As shown, in one embodiment, the stripping blade 1 of the wire harness stripping device of this application is rotatably mounted on the support frame 5, and the tilt angle is adjusted by the angle adjustment mechanism 7 to ensure that the cutting direction is consistent with the wire harness axis. The angle adjustment mechanism 7 is located at the mounting structure of the stripping blade 1, which can effectively reduce the wire harness twisting problem caused by blade angle deviation and improve the stability and accuracy of stripping. This structure, through reasonable arrangement and connection, ensures the flexibility and reliability of the blade during operation.

[0042] Specifically, the angle adjustment mechanism 7 includes an adjustment link hinged to the support frame 5. One end of the adjustment link is connected to the base of the stripping blade 1, and the other end is connected to the adjustment handle by a threaded connection, so that the user can control the tilt angle of the stripping blade 1 by rotating the adjustment handle, thereby adapting to the stripping needs of wire harnesses of different specifications.

[0043] like Figure 4As shown, in one embodiment, the feed roller 3 of the wire harness stripping device of this application has a V-shaped groove 31 on its circumferential surface, which is aligned with the V-shaped groove 31 of the guide wheel 21 to form a continuous wire harness channel, used to cooperate in preventing the wire harness from tangling. The feed roller 3 is made of elastic material and has raised particles 32 distributed on its surface to enhance the clamping force and prevent the wire harness from slipping or twisting during driving. The feed roller 3 is mounted on the support frame 5 and is arranged opposite to the guide wheel assembly 2. It works together with the guide wheel 21 to ensure that the wire harness remains stable during transmission. The limiting plate 4 is set on the outlet side of the guide wheel assembly 2 to limit the radial movement of the wire harness, further improving the stability of the wire harness transmission.

[0044] Specifically, the feed roller 3 is rotatably mounted on the support frame 5 via a bushing and is located at the outlet end of the guide wheel assembly 2. The gap between the feed roller 3 and the guide wheel 21 is adjusted by the adjusting screw 23. A limit guide groove 22 is fixed to the axial end face of the guide wheel 21, and its structure is coaxially arranged with the guide wheel 21 to limit the rotation of the wire harness. The circumferential surface of the feed roller 3 is designed with a continuous V-shaped groove 31, which corresponds to the V-shaped groove 31 of the guide wheel 21, forming a channel for the wire harness to pass through. At the same time, the elastic material and surface protrusions 32 increase the friction with the wire harness.

[0045] like Figure 2 As shown, in one embodiment, a slidable limiting block 41 is provided on the limiting plate 4 of the wire harness stripping device of this application. This limiting block is bolted to the main body of the limiting plate 4 and is used to fine-tune the radial position of the wire harness, preventing distortion caused by displacement. The limiting block 41 is located in the central region of the limiting plate 4, corresponding to the wire harness channel, and can move axially or radially on the limiting plate 4. The limiting block 41 and the limiting plate 4 are slidably engaged via a groove or guide rail, ensuring the limiting block 41 remains stable during adjustment. Simultaneously, the tightening action of the bolts fixes the limiting block 41 in a specific position, thereby effectively limiting the diameter of the wire harness and preventing radial offset from affecting the stripping accuracy.

[0046] Specifically, the limiting block 41 is installed on the surface of the limiting plate 4 through a sliding guide structure set at the top. The guide structure consists of two parallel guide rail grooves. The limiting block 41 is embedded in the guide rail grooves on both sides, and multiple threaded holes are opened on the side wall of the limiting plate 4. Position locking is achieved by screwing in bolts that pass through the through holes on the limiting block 41. This structure enables flexible adjustment of the limiting block 41, while ensuring that it will not shift due to vibration or other external forces during operation.

[0047] like Figure 2As shown, in one embodiment, a torque sensor 42 is connected to the limiting plate 4 of the wire harness stripping device of this application and fixed to the support frame 5. This torque sensor is used to monitor the circumferential rotation of the wire harness in real time and provide feedback control to correct twisting promptly. The torque sensor 42 is mechanically connected to the limiting plate 4 and can sense the torque change experienced by the limiting plate 4 during rotation, thereby determining whether the wire harness has deflected or twisted. The torque sensor 42 is mounted on the support frame 5 to ensure stable operation and prevent interference from other components. This structure helps maintain the stability of the wire harness during the stripping process and improves processing accuracy.

[0048] Specifically, the torque sensor 42 is mounted on the side of the limiting plate 4 near the support frame 5 and is directly connected to the limiting plate 4 via fasteners. Its signal output is connected to the control system to dynamically monitor and adjust the rotation state of the wiring harness. The support frame 5, as the load-bearing foundation of the overall structure, provides a stable mounting platform for the torque sensor 42 and ensures its normal operation. The connection between the sensor and the limiting plate 4 is rigid, ensuring no relative displacement occurs during operation.

[0049] like Figure 2 As shown, in one embodiment, the support frame 5 of the wire harness stripping device of this application is provided with multiple linear guide rails 51, and the guide wheel assembly 2 and the feed roller 3 are slidably mounted on the linear guide rails 51. The linear guide rails 51 extend longitudinally along the support frame 5 to provide a stable sliding path. The guide wheel assembly 2 and the feed roller 3 are connected to the linear guide rails 51 through sliders or slide blocks to realize displacement adjustment along the guide rail direction. This design can flexibly adjust the positional relationship between the guide wheel 21 and the feed roller 3 according to the size changes of the wire harness, thereby adapting to wire harnesses of different specifications and ensuring guiding accuracy and operational stability.

[0050] Specifically, the guide wheel assembly 2 and the feed roller 3 are mounted on the linear guide rail 51 via a sliding member. The sliding member has an embedded ball bearing structure to reduce frictional resistance and facilitate movement. The base of the guide wheel assembly 2 is fixed to the bottom of the sliding member with bolts, while the feed roller 3 is mounted on another sliding member via a bearing, maintaining a certain distance from the guide wheel assembly 2. The linear guide rail 51 is arranged inside the support frame 5 near the inlet and outlet areas, ensuring that the guide wheel assembly 2 and the feed roller 3 maintain good alignment during movement.

[0051] like Figure 2As shown, in one embodiment, an auxiliary guide bracket 52 is fixed on the support frame 5 of the wire harness stripping device of this application, located on the exit side of the limiting plate 4. The bracket includes a pair of guide wheels 21, used to further constrain the radial and circumferential movement of the wire harness and prevent tangling. The auxiliary guide bracket 52 is rigidly connected to the support frame 5 to ensure its stability and positioning accuracy. The bracket is set after the limiting plate 4 and in the same direction as the wire harness, serving to further guide and constrain the portion of the wire harness that has already passed through the limiting plate 4, preventing the wire harness from deviating or rotating in subsequent processes and improving the stability of the stripping process.

[0052] Specifically, the auxiliary guide bracket 52 includes two parallel guide wheels 21, which are respectively installed on both sides of the bracket and rotatably fixed to the bracket body via a rotating shaft. The axial position of the guide wheels 21 is adjusted according to the outer diameter of the wire harness so that the wire harness can pass smoothly without deviation or twisting. At the same time, in conjunction with the structure of the limiting guide groove 22 and the adjusting screw 23, the overall movement trajectory of the wire harness can be effectively controlled.

[0053] In actual operation, when this device is used, the wire harness is guided into the device by the guide wheel assembly 2. The V-shaped groove 31 on the guide wheel 21 can stably accommodate the wire harness and prevent it from deviating. At the same time, the limiting guide groove 22 restricts the circumferential rotation of the wire harness to ensure its smooth delivery. The feed roller 3 and the guide wheel assembly 2 form a channel, and the wire harness is driven forward by rotation. The limiting plate 4 performs radial positioning of the wire harness to prevent it from deviating during movement. The stripping cutter 1 is rotatably mounted on the support frame 5. As the wire harness moves forward, the cutter cuts the insulation layer of the wire harness, thereby completing the stripping operation.

[0054] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
