[0001] This utility model belongs to the field of wire harness stripping technology, specifically a wire harness stripping device. Background Technology

[0002] In wire harness processing in the automotive, electronics, and aerospace industries, wire harness stripping equipment is the core equipment for achieving precise stripping of the insulation layer. The performance of the cutting tools in its stripping components directly determines the quality of the wire harness stripping and production efficiency. However, existing wire harness stripping equipment has significant technical shortcomings in the tool cleaning and maintenance process: When a cutting tool cuts an insulating layer, it produces fine insulating debris. This debris tends to adhere to the tool surface, and the interference from the debris leads to an increase in the error of the subsequent stripping length, a decrease in the flatness of the cut, and even the problem of insulation residue. Long-term high-frequency cutting by the tool and mechanical friction with the insulating layer will accelerate the wear of the cutting edge.

[0003] Therefore, a wire harness stripping device is proposed to address the above problems. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a wire harness stripping device that dynamically removes insulation debris from the blade surface and continuously lubricates and maintains the blade, thus ensuring stripping accuracy, extending blade life, and improving production efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 7 As shown, this utility model provides a wire harness stripping device, including a frame 1, a clamping component 2 installed on the frame 1, a stripping component 3 arranged on the rear side of the clamping component 2, the stripping component 3 being arranged on the frame 1, and a cleaning and maintenance component 4 arranged below the stripping component 3. The cleaning and maintenance component 4 includes a movable frame 41. An electric telescopic rod 42 is connected to the bottom of the movable frame 41 and is mounted on the frame 1. The electric telescopic rod 42 can drive the movable frame 41 to rise and fall, allowing the narrow slit-shaped air outlet 44 and the oil roller 411 to precisely align with the working position of the blade 36, achieving proper alignment for cleaning and maintenance. A horizontal pipe 43 is installed near the top of the inner wall of the movable frame 41. A narrow slit-shaped air outlet 44 is located on the opposite side of the horizontal pipe 43. The upward-sloping air outlet 44 can directionally blow away insulating debris from the surface and surrounding area of ​​the blade 36, preventing debris adhesion from affecting the stripping accuracy. A guide pipe 45 is connected to the bottom of the horizontal pipe 43. The machine is connected to a pipe joint 46, which is connected to an air guide hose 47. An air pump 48 is connected to the end of the air guide hose 47. The air pump 48 is mounted on the frame 1. The airflow provided by the air pump 48 is delivered to the horizontal pipe 43 through the air guide hose 47 and the air guide pipe 45. The airflow is concentrated through the narrow slit-shaped air outlet 44 to efficiently remove debris. An oil box 49 is provided below the horizontal pipe 43. A roller groove 410 is opened on the opposite side of the oil box 49. An oil roller 411 is installed in the roller groove 410. The oil roller 411 passes through the oil box 49. The oil roller 411 can contact the tool 36 with the lifting and lowering of the movable frame 41, so as to evenly coat the lubricating oil in the oil box 49 onto the surface of the tool 36, reduce cutting friction, and extend the tool life.

[0018] Specifically, the clamping assembly 2 includes a fixed clamping seat 21 on the frame 1, and a corresponding movable clamping seat 22 is provided on the right side of the fixed clamping seat 21. A first cylinder 23 is connected to the side of the movable clamping seat 22 away from the fixed clamping seat 21. The first cylinder 23 is located on the frame 1 and is driven by the cylinder to achieve stable clamping of the wire harness, providing reliable positioning for the stripping operation.

[0019] Furthermore, the peeling assembly 3 includes a second cylinder 31 mounted on the frame 1. The piston rod of the second cylinder 31 is connected to a movable frame 32. A fixed seat 33 is provided on the movable frame 32. A corresponding movable seat 34 is provided on the right side of the fixed seat 33. A third cylinder 35 is connected to the side of the movable seat 34 away from the fixed seat 33. The third cylinder 35 is located on the movable frame 32. Cutters 36 are installed on opposite sides of the fixed seat 33 and the movable seat 34. Through the cooperation of multiple cylinders, the precise opening and closing and feeding of the cutters 36 can be achieved, adapting to the peeling requirements of different wire diameters.

[0020] Furthermore, the blade 36 is positioned above the movable frame 41, which has a gap 412 for the blade 36 to enter. This gap 412 allows the blade 36 to be swept by the narrow slit-shaped air outlet 44 and contacted by the oil roller 411 during the opening and closing motion, ensuring that there are no blind spots in cleaning and maintenance.

[0021] It is worth noting that the air outlet 44 is tilted upwards and is located on both sides of the blade 36. The dual-side air outlet design enhances the comprehensiveness of debris removal and avoids blind spots caused by single-side blowing.

[0022] It is worth noting that an oil inlet 413 is installed on the movable frame 41 at a position corresponding to the oil box 49. The oil inlet 413 is connected to the inner cavity of the oil box 49, which facilitates the replenishment of lubricating oil to the oil box 49 and ensures the continuity of lubrication.

[0023] It is worth mentioning that the movable frame 32 has a notch for the movable frame 41 to move, which avoids interference between the movable frame 41 and the movable frame 32 when the movable frame 41 is raised or lowered, and ensures smooth structural movement.

[0024] It is worth emphasizing that the frame 1 has a through slot for the movable frame 41 to pass through, providing space for the lifting and lowering of the movable frame 41 and adapting to the working stroke of the peeling component 3.

[0025] Among them, the first cylinder 23, the second cylinder 31, the third cylinder 35, the electric telescopic rod 42, and the air pump 48 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0026] Working principle and process: First, the wire harness is placed between the fixed clamping seat 21 and the movable clamping seat 22 of the clamping assembly 2. The first cylinder 23 drives the movable clamping seat 22 to move towards the fixed clamping seat 21, completing the clamping and positioning of the wire harness. Then, the second cylinder 31 pushes the moving frame 32, causing the fixed seat 33 and the movable seat 34 to move closer to the wire harness. The third cylinder 35 drives the movable seat 34, causing the cutters 36 on both sides to close and cut the insulation layer of the wire harness. When not in operation, the electric extension of the cleaning and maintenance assembly 4 is activated. The retracting rod 42 raises the movable frame 41, aligning the narrow slit-shaped air outlet 44 with both sides of the blade 36 of the peeling assembly 3, and the oil roller 411 is close to the blade. The airflow output by the air pump 48 is delivered to the horizontal pipe 43 through the air guide hose 47 and air guide pipe 45, and blown out at an angle from the narrow slit-shaped air outlet 44 to remove the blade 36 and surrounding insulating debris. At the same time, the oil roller 411 comes into contact with the blade 36 as the movable frame 41 rises and falls, and evenly spreads the lubricating oil in the oil box 49 onto the surface of the blade 36 to reduce cutting friction.
