Description

Technical Field

[0001] This invention relates to the field of wire stripping machine technology, and in particular to a wire end stripping machine for wiring harnesses in new energy vehicles. Background Technology

[0002] The wire stripping machine for new energy vehicle wiring harnesses is a device specifically designed for processing wiring harnesses for new energy vehicles. New energy high-voltage wiring harnesses often contain multiple layers (such as outer sheath, aluminum foil shielding layer, braided shielding mesh, and inner insulation), which need to be stripped layer by layer, requiring high processing capabilities and precision from the wire stripping machine. Therefore, in scenarios where wire specifications change frequently, especially in field repair, sample wire harness production, low-frequency wire harness processing, and complex wire harness handling, small handheld wire strippers can achieve single or multiple layer stripping by changing the blade or adjusting the cutting depth, avoiding damage to the internal core wires. They can be carried to the repair site without moving the wire harness or equipment, and can directly operate on the fault point. They are highly flexible in operation and can quickly adapt to different needs. In standard wire stripping scenarios, the blade angle of the wire stripper is usually fixed during the initial setting according to the wire specifications (such as wire diameter and sheath material). Once the blade angle is set, it cannot be rotated or adjusted during the processing of wires of the same specifications. When circumferential cutting is required, the only way is to first remove the wire, fix the blade angle to 90°, adjust the blade to a vertical cutting state, and then use a clamp to rotate the wire 360° while the blade presses down to complete the circumferential cutting. This operation is relatively cumbersome. Some devices that support rotating blades or multi-axis linkage can achieve dynamic circumferential cutting by controlling the blade angle and rotation speed through a program, but such devices are more expensive. Summary of the Invention

[0003] The purpose of this invention is to address the problem that the blade angle of wire stripping machines is usually fixed according to the wire specifications during initial setting, and once the blade angle is set, it cannot be rotated or adjusted during the processing of wires of the same specifications. When circumferential cutting is required, the operation is relatively cumbersome, and some equipment that supports rotating blades or multi-axis linkage is expensive. Therefore, this invention proposes a wire end stripping machine for new energy vehicle wiring harnesses.

[0004] To achieve the above objectives, the present invention employs the following technology: a wire stripping machine for wiring harnesses in new energy vehicles. The device includes a wire stripper housing and a wire inlet head mounted on the wire stripper housing. The wire stripper housing and the wire inlet head have a wire channel in the middle for inserting the cable. The wire stripper housing is provided with at least one cutting mechanism. The cutting mechanism includes a positioning rod that is rotatably disposed in the wire channel and abuts against the cable, and a blade that cuts into the wire sheath disposed on the positioning rod. An eccentric wheel is disposed on the positioning rod, and a steering rod is installed on the eccentric end of the eccentric wheel. The angle of the blade is adjusted by a steering mechanism set inside the wire stripper housing. The steering mechanism includes a rotating ring that is rotatably embedded in a mounting groove on the surface of the wire stripper housing. The rotating ring has several steering grooves on its surface for the steering rod to pass through. When the rotating ring rotates, the steering grooves guide the blade to deflect around the positioning rod as an axis. The cutting angle of the cutting mechanism increases or decreases according to the direction of rotation.

[0005] Further description of a wire stripping machine for wiring harnesses in new energy vehicles, as described above: An installation ring is detachably installed in the installation groove. A bracket is provided in the middle of the installation ring. A rotating ring is rotatably positioned in the gap between the installation ring and the bracket. An installation groove for the cutting mechanism is provided on the surface of the bracket.

[0006] Further description of a wire stripping machine for wiring harnesses in new energy vehicles, as described above: The mounting groove has through holes on both sides, and a knob connected to the rotating ring is rotatably installed in the mounting groove. The knob passes through the through hole and fits against the outer wall of the wire stripper housing.

[0007] Further description of a wire stripping machine for wiring harnesses in new energy vehicles, as described above: The cutting mechanism also includes a rotating seat that is rotatably embedded in the mounting slot, an eccentric wheel that is rotatably mounted at the outer end of the rotating seat, and a cutting blade that is mounted at the inner end of the rotating seat via a lifting mechanism connected to the eccentric wheel.

[0008] Further description of a wire stripping machine for wiring harnesses in new energy vehicles, as described above: The lifting mechanism includes a groove on the outer wall of the rotating seat, a guide rod is slidably embedded in the groove, the inner end of the guide rod is connected to a lifting rod slidably embedded in the rotating seat, and the blade is fixedly installed on the lifting rod. At least one limiting groove is provided on the inner wall of the lifting rod. The limiting groove is connected to the connecting rod located at the center of the lifting rod through a limiting block that is slidably embedded inside. The eccentric wheel is connected to the connecting rod.

[0009] Further description of a wire stripping machine for wiring harnesses in new energy vehicles, as described above: The guide rod moves horizontally along the length of the slide groove via an adjustment mechanism. The adjustment mechanism includes a rotating plate that is rotatably disposed in the gap between the mounting ring and the bracket. A guide groove is provided on the surface of the rotating plate for the guide rod to pass through. When the guide groove rotates, it pushes the guide rod to move horizontally.

[0010] Further description of a wire stripping machine for wiring harnesses in new energy vehicles, as described above: The wire inlet head can also be rotatably mounted on the wire stripper housing. The adjustment mechanism also includes a mounting cavity opened on the wire inlet head and a through hole opened on the mounting ring. The wire inlet head is provided with a connecting piece that passes through the through hole and is connected to the rotating plate.

[0011] Further description of a wire stripping machine for wiring harnesses in new energy vehicles, as described above: The knob and the wire inlet are fixed by a locking mechanism provided on the wire stripper housing. The locking mechanism includes an adjustment groove provided on the wire stripper housing and a mounting bracket rotatably embedded in the adjustment groove. The mounting bracket has a fixed cavity and a movable cavity fixedly installed inside the mounting bracket. Both the fixed cavity and the movable cavity are equipped with retractable insert plates via spring telescopic rods, and pushers that penetrate the fixed cavity and the movable cavity are installed on the insert plates; The wire stripper housing, wire inlet, and knob are all provided with equally spaced slots for inserting the insert plate.

[0012] Further description of a wire stripping machine for wiring harnesses in new energy vehicles, as described above: The fixed cavity and the movable cavity are slidably connected by a sliding connection part provided on the surface. The mounting bracket is set on the fixed cavity and is not connected to the movable cavity. After the insert plate set on the movable cavity is retracted into the movable cavity, the insert plate can be lowered to the inner edge of the mounting bracket to abut.

[0013] One of the above technical solutions has the following advantages or beneficial effects: 1. Through the established steering and cutting mechanisms, during wire stripping, the cable is inserted into the cable routing channel between the wire end and the stripper housing. A positioning rod restricts the cable's position, ensuring stable movement and reducing cutting tolerances during stripping. The blade's tilt angle is 10°-30° to minimize the contact area between the blade and the wire sheath, reducing cutting resistance and preventing cable deviation. As the cable slides through the routing channel, the blade cuts into the sheath from the wire end. Just before reaching the designated circumferential cutting position, the knob is rotated, positioning it in the mounting groove. Under the constraint, the rotating ring rotates in the gap between the mounting ring and the bracket. At this time, the rotating ring abuts against the steering rod through the steering groove and pushes the steering rod. The steering rod drives the eccentric wheel to rotate under the constraint of the rotating seat. At this time, the rotating seat drives the blade and the positioning rod to deflect. The included angle of the blade gradually increases to 60°-80°, and the cutting width increases at the same time. When the included angle of the blade is gradually adjusted to 90°, the blade cuts the wire insulation perpendicularly, which can ensure a flat cut and complete cutting of the wire insulation, making it easy to peel off the insulation later. This achieves the purpose of rotating the blade to adjust the angle during the cutting process, which is simple to operate. 2. With the locking mechanism in place, when the position of the positioning rod and the angle of the blade are both adjusted, and the angle of the blade no longer needs to be adjusted during the stripping process, the knob and the wire feed head are fixed by the locking mechanism set on the wire stripper housing to prevent accidental contact with the knob and the wire feed head during operation. Under the push of the spring telescopic rod, the insert plate moves horizontally in the fixed cavity and the movable cavity and inserts into the slots opened on the surface of the wire feed head and the knob. Under the restriction of the insert plate and the slots, the wire feed head and the knob cannot be rotated for adjustment. Attached Figure Description

[0016] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a wire stripping machine for wiring harnesses of new energy vehicles. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] To address the issue that the blade angle of wire stripping machines is typically fixed during initial setup based on wire specifications, making it impossible to rotate or adjust the blade angle when processing wires of the same specification, resulting in cumbersome operation when circumferential cutting is required, and the high cost of some devices supporting rotating blades or multi-axis linkage, this invention proposes a wire end stripping machine for new energy vehicle wiring harnesses. Figure 1 - Figure 18 As shown: The stripper includes a wire stripper housing 11 and a wire inlet head 12 mounted on the wire stripper housing 11. A wire routing channel 13 for cable insertion is provided in the middle of the wire stripper housing 11 and the wire inlet head 12. The wire stripper housing 11 contains four cutting mechanisms 30 and a steering mechanism 20 for adjusting the angle of the cutting mechanisms 30. Figures 3-8As shown, the steering mechanism 20 includes a rotating ring 25 that is rotatably embedded in a mounting groove 21 on the surface of the wire stripper housing 11. The rotating ring 25 has four steering grooves 27 for the steering rod 35 to pass through. A mounting ring 22 is detachably installed in the mounting groove 21. A bracket 23 is provided in the middle of the mounting ring 22. The rotating ring 25 is rotatably positioned in the gap between the mounting ring 22 and the bracket 23. The bracket 23 has mounting slots 24 on its surface for the cutting mechanism 30 to be installed. like Figures 8-10 As shown, the cutting mechanism 30 includes a positioning rod 32 rotatably disposed in the cable routing channel 13 and abutting against the cable, and a blade 33 disposed on the positioning rod 32 to cut into the cable sheath. An eccentric wheel 34 is disposed on the positioning rod 32, a steering rod 35 is mounted on the eccentric end of the eccentric wheel 34, and a rotating seat 31 is rotatably embedded in the mounting slot 24. The eccentric wheel 34 is rotatably mounted at the outer end of the rotating seat 31. The blade 33 is disposed at the inner end of the rotating seat 31 through a lifting mechanism 40 connected to the eccentric wheel 34. To facilitate operation, rotate the rotating ring 25, such as Figures 1-3 As shown, through holes are provided on both sides of the mounting groove 21. A knob 26 connected to the rotating ring 25 is rotatably installed inside the mounting groove 21. The knob 26 passes through the through hole and fits against the outer wall of the wire stripper housing 11. Rotating the knob 26 will drive the mounting ring 22 to rotate. During wire stripping, the cable is inserted into the wire end 12 and the wire routing channel 13 opened in the wire stripper housing 11. The position of the cable is restricted by the positioning rod 32 to keep the cable moving stably during the stripping process and reduce the cutting tolerance. At this time, the inclination angle of the blade 33 is 10°-30° to reduce the contact area between the blade 33 and the wire sheath, reduce the cutting resistance, and prevent the cable from deviating. As the cable slides in the wire routing channel 13, the blade 33 cuts into the wire sheath from the wire end and cuts into the wire sheath just before reaching the designated position. When the ring cutting position is reached, start rotating the knob 26. Under the constraint of the mounting groove 21, the knob 26 drives the rotating ring 25 to rotate in the gap between the mounting ring 22 and the bracket 23. At this time, the rotating ring 25 abuts against the steering rod 35 through the steering groove 27 and pushes the steering rod 35. The steering rod 35 drives the eccentric wheel 34 to rotate under the constraint of the rotating seat 31. At this time, the rotating seat 31 drives the blade 33 and the positioning rod 32 to deflect. The included angle of the blade 33 gradually increases to 60°-80°, and the cutting width increases at the same time. When the included angle of the blade 33 is gradually adjusted to 90°, the blade 33 cuts the wire insulation vertically, which can ensure a flat cut and complete cutting of the wire insulation, making it easy to peel off the insulation later. This achieves the purpose of rotating the blade 33 to adjust the angle during the cutting process, which is simple to operate. Furthermore, when it is not necessary to cut the wire sheath by circumferential cutting, the clamp of the blade 33 can be adjusted and fixed within the angle range of 15°-45°, with its cutting direction into the wire sheath forming an angle with the wire axis. During the cable conveying or moving the stripper housing 11, the lateral force of the blade 33 on the wire sheath will drive the cable to rotate around its own axis. When the angle of the blade 33 and the wire conveying speed are matched, the cable can be self-rotating and cutting, forming a continuous spiral cut. After the high-voltage wiring harness of new energy vehicles adopts spiral cutting, the spiral cut allows the wire sheath to slide slightly, avoiding stress concentration and improving fatigue life.

[0018] The rotating seat 31 is rotatably installed in the mounting slot 24, and the eccentric wheel 34 is rotatably installed at the outer end of the rotating seat 31. To enable the positioning rod 32 to fix cables of different diameters within a certain range, such as... Figure 8 , Figures 9-12 As shown, the blade 33 is disposed at the inner end of the rotating seat 31 via a lifting mechanism 40 connected to the eccentric wheel 34. The lifting mechanism 40 includes a groove 41 opened on the outer wall of the rotating seat 31. A guide rod 42 is slidably embedded in the groove 41. The inner end of the guide rod 42 is connected to a lifting rod 43 slidably embedded in the rotating seat 31. The blade 33 is fixedly installed on the lifting rod 43. At least one limiting groove 44 is opened on the inner wall of the lifting rod 43, the same number as the groove 41. The limiting groove 44 is connected to a connecting rod 46 located at the axis of the lifting rod 43 via a limiting block 45 slidably embedded inside. The eccentric wheel 34 is connected to the connecting rod 46. When the position of the positioning rod 32 needs to be adjusted, the guide rod 42 is pushed so that it moves horizontally along the length of the slide groove 41 under the restriction of the slide groove 41. The guide rod 42 drives the lifting rod 43 to slide under the restriction of the connecting rod 46. At the same time, the lifting rod 43 drives the limiting groove 44 to slide under the restriction of the limiting block 45. The position adjustment of the positioning rod 32 and the blade 33 is completed.

[0019] Furthermore, in order to achieve synchronous adjustment of the positions of the four positioning rods 32 and the blades 33, and to avoid damage to the copper core caused by different cutting depths of the four blades 33 into the cable, such as... Figure 8 , Figures 13-15The wire inlet head 12 is rotatably mounted on the wire stripper housing 11. The guide rod 42 moves horizontally along the length of the slide groove 41 via an adjustment mechanism 50. The adjustment mechanism 50 includes a rotating plate 53 rotatably mounted in the gap between the mounting ring 22 and the bracket 23. The rotating plate 53 has a guide groove 54 for the guide rod 42 to pass through, a mounting cavity 51 on the wire inlet head 12, and a through hole 55 on the mounting ring 22. The wire inlet head 12 is provided with a connecting piece 52 that passes through the through hole 55 and connects to the rotating plate 53. By rotating the wire inlet head 12... 2. The wire inlet head 12 drives the connector 52 to slide under the restriction of the through hole 55. When the connector 52 drives the rotating plate 53 to rotate, the rotating plate 53 abuts against the guide rod 42 through the opened guide groove 54. Under the push of the guide groove 54, the guide rod 42 moves horizontally along the length direction of the slide groove 41. When the connector 52 moves from one end of the through hole 55 to the other end, the guide rod 42 also moves from one end of the guide groove 54 to the other end. At this time, the positioning rod 32 and the blade 33 extend from the position farthest from the axis of the wire channel 13 to the closest position.

[0020] When the position of the positioning rod 32 and the angle of the blade 33 are both adjusted, and the angle of the blade 33 no longer needs to be adjusted during the wire stripping process, in order to avoid accidentally touching the knob 26 and the wire feed head 12 during operation, such as Figures 16-17 As shown, the knob 26 and the wire inlet 12 are fixed by a locking mechanism 60 provided on the wire stripper housing 11. The locking mechanism 60 includes an adjustment groove 64 provided on the wire stripper housing 11. The mounting bracket 63 is rotatably embedded in the adjustment groove 64. The mounting bracket 63 has a fixed cavity 61 and a movable cavity 62 fixedly installed inside. Both the fixed cavity 61 and the movable cavity 62 are provided with a retractable insert plate 65 by means of a spring telescopic rod 67. The insert plate 65 is equipped with a pusher 68 that penetrates the fixed cavity 61 and the movable cavity 62. The wire stripper housing 11, the wire inlet 12 and the knob 26 are all provided with slots 66 at equal intervals around the insert plate 65 for insertion. Driven by the spring telescopic rod 67, the insert plate 65 moves horizontally within the fixed cavity 61 and the movable cavity 62. The insert plate 65 is inserted into the slots 66 on the surfaces of the adjusted inlet head 12 and the knob 26. Under the restriction of the insert plate 65 and the slots 66, the inlet head 12 and the knob 26 cannot be rotated for adjustment. At the same time, when adjusting, by pushing the pusher 68, the pusher 68 causes the insert plate 65 to press against the spring telescopic rod 67. The spring telescopic rod 67 retracts and moves the insert plate 65 out of the slot 66. At this time, the mounting bracket 63 is rotated, causing the mounting bracket 63 to rotate the fixed cavity 61 and the movable cavity 62 under the restriction of the adjustment groove 64. This causes the position of the insert plate 65 to no longer correspond to the slot 66. The insert plate 65 is abutted, preventing the spring telescopic rod 67 from elastically deforming and recovering. The inlet head 12 and the knob 26 can always remain in a rotatable and adjustable state.

[0021] like Figure 18 As shown, the fixed cavity 61 and the movable cavity 62 can also be slidably connected by a sliding connection part 69 provided on the surface. The mounting bracket 63 is set on the fixed cavity 61 and is not connected to the movable cavity 62. With this design, the movable cavity 62 can lock the inlet head 12 with the insert plate 65 provided in the fixed cavity 61, while pushing the insert plate 65 in the movable cavity 62 to move out of the slot 66. After the insert plate 65 is fully retracted into the movable cavity 62, by pulling the movable cavity 62, the movable cavity 62 drives the insert plate 65 to descend under the guidance of the sliding connection part 69 to abut against the inner edge of the mounting bracket 63, so that the insert plate 65 cannot pop out of the movable cavity 62. At this time, the fixed cavity 61 and the insert plate 65 provided inside cooperate with the slot 66 to lock the inlet head 12. When the diameter of the cable remains unchanged, the positioning rod 32 can always fix the cable. At the same time, the restriction of the rotating ring 25 by the movable cavity 62 and the insert plate 65 provided inside is released. At this time, the angle of the blade 33 can be continuously adjusted by rotating the rotating ring 25 during the wire stripping process.

[0022] Working principle: The cable to be stripped is inserted into the cable routing channel 13 opened in the middle of the cable stripper housing 11 and the cable inlet head 12. The positioning rod 32 in the cutting mechanism 30 abuts against the cable to restrict the position of the cable, ensuring that the cable remains stable during the stripping process and reducing cutting tolerance. The blade 33 initially cuts into the wire sheath at an inclination angle of 10°-30° to reduce the contact area between the blade 33 and the wire sheath, reduce cutting resistance, and prevent the cable from shifting. When the cable slides close to the designated circumferential cutting position, the knob 26 is rotated to drive the rotation... The rotating ring 25 rotates in the gap between the mounting ring 22 and the bracket 23. The steering groove 27 on the surface of the rotating ring 25 pushes the steering rod 35, which in turn drives the eccentric wheel 34 to rotate under the restriction of the rotating seat 31. The rotation of the eccentric wheel 34 causes the blade 33 and the positioning rod 32 to deflect. The included angle of the blade 33 gradually increases to 60°-80°, and the cutting width also increases accordingly. When the included angle of the blade 33 is adjusted to 90°, the blade 33 cuts the wire insulation vertically to ensure a flat cut and complete cutting of the wire insulation, which facilitates subsequent stripping operations. When circumferential cutting is not required, the angle of the blade 33 can be adjusted and maintained within the range of 15°-45° so that the direction of cutting into the wire sheath forms an angle with the wire axis. During the process of cable conveying or moving the stripper housing 11, the lateral force of the blade 33 on the wire sheath drives the cable to rotate around its own axis, forming a continuous spiral cut. The spiral cut allows the wire sheath to slide slightly, avoids stress concentration, and improves fatigue life. The positions of the positioning rod 32 and the blade 33 are adjusted synchronously. By rotating the wire inlet head 12, the connector 52 is driven to slide in the through hole 55, which in turn drives the rotating plate 53 to rotate. The guide groove 54 on the surface of the rotating plate 53 pushes the guide rod 42 to move horizontally along the length of the slide groove 41, so as to realize the synchronous adjustment of the positions of the four positioning rods 32 and the blade 33, and avoid damage to the copper core caused by different cutting depths. When the position of the positioning rod 32 and the angle of the blade 33 are adjusted and no further adjustment is needed during the wire stripping process, the locking mechanism 60 is used to fix the knob 26 and the wire inlet 12. The spring telescopic rod 67 pushes the insert plate 65 into the slot 66 opened on the surface of the knob 26 and the wire inlet 12 to prevent accidental operation from causing the knob 26 and the wire inlet 12 to rotate.

[0023] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art who makes equivalent substitutions or modifications to the wire end stripping machine for new energy vehicle wiring harnesses and its inventive concept according to the present invention within the scope of the technology disclosed in the present invention should be covered within the scope of protection of the present invention.
