Description

Technical Field

[0001] This utility model relates to the field of cutting technology, specifically to an adjustable cutting device for automotive wiring harness production. Background Technology

[0002] With the continuous development of the automotive industry and the increasing sophistication of automotive functions, the demand for wiring harnesses has increased significantly, while the requirements for the precision and versatility of wiring harness processing are also constantly rising. In the wiring harness production process, the cutting process is an indispensable and crucial step, but traditional automotive wiring harness cutting methods have many shortcomings.

[0003] In existing technologies, most cutting devices simply cut the wire harness by moving the blade. However, due to the lack of effective buffering and stabilizing auxiliary structures, the blade is prone to shaking or deviating at the moment of contact with the wire harness and during the cutting process due to factors such as uneven force and excessive impact, which can lead to problems such as uneven cuts and damage to the core wires inside the wire harness. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: an adjustable cutting device for automotive wiring harness production, comprising: a cutting device, with scale rods slidably connected to both sides of the cutting device, a fixed base fixedly connected to the end of the scale rods away from the cutting device, a lower clamping plate fixedly connected to the inner side of the fixed base, an upper clamping plate slidably connected to the inner side of the fixed base, and a locking screw rotatably connected to the top of the upper clamping plate. By pulling the fixed base, the scale rods are slidably moved along the cutting device, thereby adjusting the position of the fixed base and flexibly adjusting the spacing between the fixed bases according to the requirements of the wiring harness length, position, etc.

[0005] A wire stripping device is used to strip the wire from the ends of a wire harness after it has been cut by a cutting device. The two sides of the cutting device are fixedly connected to the outside of the wire stripping device. The wire stripping device can be used to strip the wire from the ends of the cut wire harness.

[0006] The cutting device includes a base, a drive motor fixedly connected to the outer side of the base, a positive and negative lead screw fixedly connected to the output end of the drive motor, a cutting blade threaded to the outer wall of the positive and negative lead screw, connecting plates fixedly connected to both sides of the cutting blade, a limit rod slidably connected to the inner wall of the connecting plate, a clamping plate fixedly connected to the outer side of the limit rod, and a compression spring fixedly connected to the outer side of the clamping plate. When the drive motor on the outer side of the base is started, the output end of the drive motor drives the positive and negative lead screw to rotate. When the positive and negative lead screw rotates, the cutting blade moves along the axial direction of the positive and negative lead screw. At the same time, the two cutting blades move closer to each other.

[0007] Preferably, the outer side of the scale rod is slidably connected to the inner walls of both sides of the base, the outer wall of the upper clamping plate is slidably connected to the outer wall of the lower clamping plate, and the inner wall of the top of the fixing seat is threadedly connected to the inner wall of the locking screw. Rotating the locking screw causes the upper clamping plate to move downward, cooperating with the lower clamping plate to clamp and fix the wire harness.

[0008] Preferably, the two ends of the positive and negative lead screws are rotatably connected to the inner side of the base, the inner side of the base is slidably connected to the bottom of the cutting blade, and the end of the compression spring away from the clamping plate is fixedly connected to the outer wall of the connecting plate. Under the action of the compression spring, the clamping plate can play a certain role in buffering and assisting in stabilizing the movement of the cutting blade.

[0009] Preferably, the wire stripping device includes an annular fixing block, an annular turntable is rotatably connected to the outer side of the annular fixing block, an adjusting screw is rotatably connected to the outer side of the annular turntable, a sliding frame is threadedly connected to the outer wall of the adjusting screw, and a wire stripping knife is fixedly connected to the bottom of the sliding frame. The relative position of the wire stripping knife and the wire bundle is precisely adjusted by adjusting the position of the sliding frame so that it can accurately cut into the outer sheath of the wire bundle.

[0010] Preferably, a lever is fixedly connected to the outer side of the annular turntable. The levers are arranged in a ring along the central axis of the annular turntable, and the operator can rotate the annular turntable along the annular fixed block by moving the levers.

[0011] Preferably, the outer side of the sliding frame is slidably connected to the outer wall of the annular turntable, and the outer side of the annular fixing block is fixedly connected to both sides of the base. When the adjusting screw is rotated, the sliding frame will move up and down along the outer wall of the annular turntable.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a scale rod to adjust the position of the fixed seat by pulling the fixed seat and causing the scale rod to slide along the cutting device. This allows for flexible adjustment of the spacing between the fixed seats according to the length and position of the wire harness. After placing the wire harness on the lower clamping plate, the locking screw is rotated to move the upper clamping plate downwards, which, together with the lower clamping plate, clamps and fixes the wire harness. Then, the cutting device can be used to cut the automotive wire harness to the required length.

[0014] 2. This utility model, by setting a cutting device, allows the compression spring to be gradually compressed as the cutting blades on both sides approach each other during the cutting process of the wire harness. This forces the limiting rod to slide along the surface of the connecting plate. During the movement of the cutting blade, the clamping plates on both sides first contact the surface of the wire harness. Under the action of the compression spring, the clamping plates can provide a certain buffer and auxiliary stabilization for the movement of the cutting blade, ensuring that the cutting blade smoothly cuts the wire harness to the required length.

[0015] 3. This utility model incorporates a wire stripping device. When the adjusting screw is rotated, the sliding frame moves up and down along the outer wall of the annular turntable. This allows for precise adjustment of the relative position of the wire stripper and the wire harness by adjusting the position of the sliding frame, ensuring accurate cutting into the outer sheath of the wire harness. After adjusting the position of the wire stripper, operating the wire stripping device causes the wire stripper to cut the outer sheath at the end of the wire harness, thus completing the wire stripping operation and removing the outer sheath from the end of the wire harness, achieving the purpose of wire stripping.

[0022] Example: Please refer to Figure 1 - Figure 4 This utility model provides a technical solution: an adjustable cutting device for automotive wiring harness production, comprising:

[0023] The cutting device 1 has scale rods slidably connected to both sides of it. A fixed base 3 is fixedly connected to the end of the scale rods 2 away from the cutting device 1. A lower clamping plate 4 is fixedly connected to the inner side of the fixed base 3, and an upper clamping plate 5 is slidably connected to the inner side of the fixed base 3. A locking screw 6 is rotatably connected to the top of the upper clamping plate 5. A wire stripping device 7 is used to strip the wire ends cut by the cutting device 1. The two sides of the cutting device 1 are fixedly connected to the outer sides of the wire stripping device 7. The outer sides of the scale rods 2 are slidably connected to the inner walls of both sides of the base 11, and the outer walls of the upper clamping plate 5 and the lower clamping plate 4 are slidably connected. The sliding connection is achieved by threading the inner wall of the top of the fixed seat 3 with the inner wall of the locking screw 6. By pulling the fixed seat 3, the scale rod 2 is driven to slide along the cutting device 1, thereby adjusting the position of the fixed seat 3. This allows for flexible adjustment of the spacing between the fixed seats 3 according to the requirements of the wire harness length and position. After placing the wire harness on the lower clamping plate 4, the locking screw 6 is rotated to move the upper clamping plate 5 downwards, which, together with the lower clamping plate 4, clamps and fixes the wire harness. Then, the cutting device 1 can be used to cut the automotive wire harness to the required length. Subsequently, the wire stripping device 7 is used to strip the cut wire harness ends.

[0024] The cutting device 1 includes a base 11. A drive motor 12 is fixedly connected to the outer side of the base 11. A positive and negative lead screw 13 is fixedly connected to the output end of the drive motor 12. A cutting blade 14 is threadedly connected to the outer wall of the positive and negative lead screw 13. Connecting plates 15 are fixedly connected to both sides of the cutting blade 14. A limit rod 16 is slidably connected to the inner wall of the connecting plate 15. A clamping plate 17 is fixedly connected to the outer side of the limit rod 16. A compression spring 18 is fixedly connected to the outer side of the clamping plate 17. The two ends of the positive and negative lead screw 13 are rotatably connected to the inner side of the base 11. The inner side of the base 11 is slidably connected to the bottom of the cutting blade 14. The end of the compression spring 18 away from the clamping plate 17 is fixedly connected to the outer wall of the connecting plate 15. When cutting the wire harness, the base 11 is activated. The outer drive motor 12 drives the positive and negative lead screws 13 to rotate. When the positive and negative lead screws 13 rotate, the cutting blade 14 moves along the axial direction of the positive and negative lead screws 13. At the same time, as the two cutting blades 14 approach each other, during the cutting process of the cutting blades 14 on the wire harness, the compression spring 18 is gradually compressed, forcing the limit rod 16 to slide along the surface of the connecting plate 15. During the movement of the cutting blade 14, the clamping plates 17 on both sides first contact the surface of the wire harness. Under the action of the compression spring 18, the clamping plates 17 can play a certain role in buffering and assisting in stabilizing the movement of the cutting blade 14, ensuring that the cutting blade 14 smoothly cuts the wire harness to the required length.

[0025] The wire stripping device 7 includes an annular fixing block 71, an annular turntable 72 rotatably connected to the outer side of the annular fixing block 71, an adjusting screw 74 rotatably connected to the outer side of the annular turntable 72, a sliding frame 75 threadedly connected to the outer wall of the adjusting screw 74, a wire stripper 76 fixedly connected to the bottom of the sliding frame 75, a lever 73 fixedly connected to the outer side of the annular turntable 72, the lever 73 being arranged annularly along the central axis of the annular turntable 72, the outer side of the sliding frame 75 being slidably connected to the outer wall of the annular turntable 72, and the outer side of the annular fixing block 71 being connected to the base 1. The two sides of the device are fixedly connected. After the cutting operation is completed, the wire harness end can be stripped. The operator can rotate the annular turntable 72 along the annular fixed block 71 by turning the lever 73 to perform subsequent adjustment operations. When the adjusting screw 74 is rotated, the sliding frame 75 will move up and down along the outer wall of the annular turntable 72. The bottom of the sliding frame 75 is fixedly connected to the wire stripper 76. In this way, the relative position of the wire stripper 76 and the wire harness can be precisely adjusted by adjusting the position of the sliding frame 75 so that it can accurately cut into the outer sheath of the wire harness. After the position of the wire stripper 76 is adjusted, the wire stripping device 7 is operated so that the wire stripper 76 cuts the outer sheath of the wire harness end, thereby completing the wire stripping operation and removing the outer sheath of the wire harness end to achieve the purpose of wire stripping.

[0026] Working principle: In use, by pulling the fixed seat 3, the scale rod 2 is slid along the cutting device 1 to adjust the position of the fixed seat 3. The spacing between the fixed seats 3 can be flexibly adjusted according to the length, position and other requirements of the wire harness. After the wire harness is placed on the lower clamping plate 4, the locking screw 6 is rotated to move the upper clamping plate 5 downward, which works with the lower clamping plate 4 to clamp and fix the wire harness. Then the cutting device 1 can be used to cut the automotive wire harness to the required length. Then the wire stripping device 7 is used to strip the wire ends of the cut wire harness.

[0027] When cutting the wire harness, the drive motor 12 on the outside of the base 11 is started. The output end of the drive motor 12 drives the positive and negative lead screws 13 to rotate. When the positive and negative lead screws 13 rotate, the cutting blade 14 will move along the axial direction of the positive and negative lead screws 13. At the same time, as the two cutting blades 14 approach each other, during the process of the cutting blades 14 cutting the wire harness, the compression spring 18 is gradually compressed, forcing the limit rod 16 to slide along the surface of the connecting plate 15. During the movement of the cutting blade 14, the clamping plates 17 on both sides first contact the surface of the wire harness. Under the action of the compression spring 18, the clamping plates 17 can play a certain role in buffering and assisting in stabilizing the movement of the cutting blade 14, ensuring that the cutting blade 14 smoothly cuts the wire harness and cuts the wire harness to the required length.

[0028] After the cutting operation is completed, the wire harness end can be stripped. The operator can rotate the annular turntable 72 along the annular fixed block 71 by moving the lever 73 to perform subsequent adjustment operations. When the adjusting screw 74 is rotated, the sliding frame 75 will move up and down along the outer wall of the annular turntable 72. This allows for precise adjustment of the relative position between the wire stripper 76 and the wire harness by adjusting the position of the sliding frame 75, ensuring accurate cutting into the outer sheath of the wire harness. After adjusting the position of the wire stripper 76, the wire stripping device 7 is operated to cut the outer sheath of the wire harness end, thereby completing the wire stripping operation and removing the outer sheath of the wire harness end to achieve the purpose of wire stripping.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
