Description

Technical Field

[0001] The invention relates to the technical field of wire harness processing, in particular to a stripping device for processing electronic wire harnesses. Background Art

[0002] Electronic wiring harnesses are used in electronic devices and provide them with power and signal transmission. The wiring harness consists of an outermost sheath, a wire core located inside the sheath, and an insulating skin wrapped around the outside of the wire core. In order to achieve the basis of circuit connection, the stripping process will expose the wire core inside the wire. The exposed conductor can directly contact other components or wires to form a circuit path.

[0003] The patent publication number of the existing patent application is: CN214958382U, and the publication date is November 30, 2021. The name of the patent is "A multifunctional wire stripping mechanism for wire processing". The patent includes a base and a support frame, the upper end of the base is connected to the support frame, the bottom of the base is connected to a universal wheel, and a brake is provided on the universal wheel. A column is connected to the middle position of the upper end of the base, and the end of the column is connected to the guide groove. A ball screw is connected to the upper right end of the base, and the upper end of the ball screw is connected to the inner top of the support frame. The upper end of the ball screw is connected to a nut seat, and one side of the nut seat is connected to a connecting rod. The utility model arranges a lifting cylinder, a cutting tool, a column, a guide groove and a wire stripping knife, and utilizes the mutual cooperation between them, so that the wires can be stripped and cut. It has strong functionality, is easy to use, and has high wire stripping efficiency. Secondly, by arranging universal wheels, it can be easy to move.

[0004] The above application has shortcomings. Although general wire stripping machines have the dual functions of stripping and cutting, their stripping methods are mostly relatively simple, mainly relying on the direct action of the wire stripping knife, and also require multiple independent steps or complex mechanisms to perform linear cutting and circular cutting on the wire harness surface respectively. It is not possible to quickly and flexibly switch between the two stripping methods, resulting in different lengths of the wire cores that need to be exposed on the wire harness, which reduces the processing efficiency. Summary of the invention

[0005] The object of the present invention is to provide a stripping device for electronic wire harness processing to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

A plurality of elastic clamps are distributed in a ring in the ring-cutting and peeling mechanism, and a one-way transmission member is installed between the wire harness guiding mechanism and the ring-cutting and peeling mechanism. When the wire harness guiding mechanism guides the cable to pass through the elastic clamp, the stripping knife cuts the cable skin, and when the wire harness guiding mechanism rotates in the opposite direction, the ring-cutting and peeling mechanism ring-cuts the cable skin and pushes it outward under the drive of the one-way transmission member.

[0008] Preferably, the harness guiding mechanism comprises a driving spindle rotatably connected to both sides of the frame, friction guide rings are symmetrically and coaxially sleeved on the driving spindle, and a bidirectional screw rod respectively connected to two friction guide rings is rotatably mounted on the front surface of the frame.

[0009] Preferably, the circumcision and peeling mechanism includes an L-shaped bracket slidably mounted on the top of the base, a threading sleeve is fixedly connected to the top of the L-shaped bracket, a circumcision blade disc is rotatably mounted on one end of the threading sleeve, and a torsion spring is provided between the two.

[0011] Preferably, an adjusting screw is installed through the thread on the top of the frame, the bottom end of the adjusting screw passes through the lifting and adjusting frame and is installed with an anti-slip nut, the adjusting screw is fixedly connected to a limit ring above the lifting and adjusting frame, a compression spring is installed between the limit ring and the lifting and adjusting frame, a connecting column is installed in the lifting and adjusting frame, and the peeling knife is installed on the connecting column.

[0012] Preferably, both ends of the driving main shaft are fixedly connected with ratchets, the bottom of the lifting and adjusting frame is slidably connected with an abutment rack, one side of the abutment rack is unidirectionally meshed with the ratchet, and a top spring is installed between the other side of the abutment rack and the lifting and adjusting frame.

[0013] Preferably, a plurality of circular cutting blades are movably inserted in the circular cutting cutter disc, and a distance adjusting ring is rotatably sleeved in the circular cutting cutter disc. A slider is fixedly connected to one side of the circular cutting blade, and an arc groove for the slider to move is opened on the distance adjusting ring.

[0014] Preferably, a transmission switching assembly is installed in the frame, and when the lifting and adjusting frame lifts up the transmission switching assembly, the transmission ring is transmission-connected with the distance adjustment ring through the transmission switching assembly.

[0015] Preferably, a ring is nested at the center of the stripping knife, an elastic block plugged with the ring is horizontally installed on the connecting column, and a threaded crimping sleeve that presses the elastic block and the ring in turn is symmetrically sleeved on the connecting column.

[0016] Preferably, the elastic clamping member includes a pressure rod passing through the threading sleeve, the pressure rod is elastically connected to the inner wall of the threading sleeve, and one end of the pressure rod is provided with a roller inside the threading sleeve, and the other end is provided with a guide groove along the axis outside the threading sleeve, and the outer wall of the threading sleeve is slidably connected with a clamping cap adapted to the guide groove.

[0017] In the above technical scheme, a wire harness guiding mechanism is provided to enable the wire harness to be automatically cut when passing through the stripping knife, which is convenient for subsequent stripping. At the same time, a ring-cutting and stripping mechanism is introduced. When the wire harness guiding mechanism rotates in the opposite direction, it can be linked with the ring-cutting and stripping mechanism through a one-way transmission member, making the switching of the two stripping operations easier and faster. After the one-way transmission member plays a linkage role, it can not only push the ring-cut epidermis outward, thereby improving the continuity and efficiency of stripping, but also ensure that the ring-cutting and stripping mechanism can be driven in the correct direction, avoiding the wire harness stripping method. If an error occurs, the forward and reverse rotation of the harness guide mechanism will drive the stripping knife to perform linear cutting or the circular cutting and peeling mechanism to perform circular cutting. Linear cutting can quickly and accurately cut the cable surface, preparing for subsequent circular cutting and peeling, while circular cutting and peeling can quickly and continuously peel off the surface and reduce damage to the internal conductor. If the harness guide mechanism continues to rotate forward to push the harness forward, the circular cutting and peeling mechanism will not perform circular cutting on the harness to ensure the long-distance stripping requirements, so that the two stripping methods can be flexibly switched, and the stripping knife can cooperate with the circular cutting and peeling mechanism.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0034] See also Figure 1-10 A stripping device for electronic wire harness processing provided by an embodiment of the present invention includes a base 1 and a frame 2 installed on the top of the base 1, and also includes a wire harness guide mechanism 3, which is rotatably installed in the frame 2, and a lifting and adjusting frame 7 is movably installed in the frame 2, and a stripping knife 9 is installed in the lifting and adjusting frame 7, and a ring cutting and peeling mechanism 4 is slidably installed on the base 1 and located behind the wire harness guide mechanism 3. A plurality of elastic clamping members 5 are distributed in a ring shape in the ring cutting and peeling mechanism 4, and a one-way transmission member 6 is installed between the wire harness guide mechanism 3 and the ring cutting and peeling mechanism 4. When the wire harness guide mechanism 3 guides the cable to pass through the elastic clamping member 5, the stripping knife 9 cuts the cable skin, and when the wire harness guide mechanism 3 rotates in the opposite direction, the ring cutting and peeling mechanism 4 ring cuts the cable skin and pushes it outward under the drive of the one-way transmission member 6.

[0035] Specifically, the wire harness guiding mechanism 3 is located at the wire harness entrance position on the frame 2, and the stripping knife 9 and the circumcision and peeling mechanism 4 are both behind the wire harness guiding mechanism 3. During the stripping process, the wire harness guiding mechanism 3 is responsible for accurately guiding the cables to the working area of ​​the stripping knife 9 and the circumcision and peeling mechanism 4. The end of the wire harness guiding mechanism 3 is connected to a driving motor 306 for automatically driving the cables forward. The circumcision and peeling mechanism 4 that can slide back and forth on the base 1 is located behind the stripping knife 9, and a plurality of elastic clamping members 5 are distributed in an annular shape inside the circumcision and peeling mechanism 4. These elastic clamping members 5 cooperate to clamp the cables under the action of elastic force, so that the position of the cables is more stable during the cutting and circumcision process. During stripping, the height of the lifting and adjusting frame 7 is adjusted in advance to allow the stripping knife 9 to be in a suitable position, and the electronic wire harness to be processed is placed on the wire harness. On the guide channel of the harness guide mechanism 3, the starting device allows the harness guide mechanism 3 to rotate forward, guiding the cable to move forward to the working area of ​​the stripping knife 9, and the cable skin is cut by the stripping knife 9. As long as the harness guide mechanism 3 continues to guide the external harness forward, the cutting distance will gradually increase, which is convenient for the overall stripping of a section of the harness. When it is necessary to strip only a part of the skin at the end of the harness, first let the stripping area enter the circumferential cutting and peeling mechanism 4, and then hold the harness from the outside of the device, and control the harness guide mechanism 3 to rotate in the opposite direction. Then, the one-way transmission member 6, driven by the reverse rotation of the harness guide mechanism 3, pushes the skin cut by the circumferential cutting and peeling mechanism 4 outward, so that the cut skin and the wire core are staggered, so that after the harness is pulled out, the skin can be quickly separated from the wire core to complete the entire stripping process.

[0036] Compared with the prior art, the embodiment of the present invention sets a wire harness guiding mechanism 3 to enable the wire harness to realize the function of automatic cutting when passing through the skinning knife 9, which is convenient for subsequent skinning, and also introduces a ring cutting and skinning mechanism 4. When the wire harness guiding mechanism 3 rotates in the opposite direction, it can be linked with the ring cutting and skinning mechanism 4 through the one-way transmission member 6, so that the switching between the two skinning operations is simpler and faster. After the one-way transmission member 6 plays a linkage role, it can not only make the skin after skinning be pushed outward, thereby improving the continuity and efficiency of skinning, but also ensure that the ring cutting and skinning mechanism 4 can be driven in the correct direction to avoid wire harness skinning. If the skinning method is wrong, the forward and reverse rotation of the wire harness guide mechanism 3 will drive the stripping knife 9 to perform linear cutting or the circular cutting and peeling mechanism 4 to perform circular cutting. The linear cutting can quickly and accurately cut the cable skin, preparing for the subsequent circular cutting and peeling. The circular cutting and peeling can quickly and continuously peel off the skin and reduce damage to the internal conductor. If the wire harness guide mechanism 3 continues to rotate forward to push the wire harness forward, the circular cutting and peeling mechanism 4 will not perform circular cutting on the wire harness to ensure the long-distance stripping requirements, so that the two stripping methods can be flexibly switched, and the stripping knife 9 can cooperate with the circular cutting and peeling mechanism 4 to work.

[0037] In a further embodiment of the present invention, the wire harness guide mechanism 3 includes a driving spindle 301 rotatably connected to both sides of the frame 2, a driving motor 306 on the outside of the frame 2 is connected to the driving spindle 301, a friction guide ring 302 is symmetrically and coaxially sleeved on the driving spindle 301, one side of the friction guide ring 302 is conical, and the other side is equipped with a bearing, and a bidirectional screw rod 303 connected to the two friction guide rings 302 is rotatably installed on the front surface of the frame 2, and a cross bar is fixedly connected to one side of the bearing, and the bidirectional screw rod 303 passes through the two cross bars and is threadedly connected thereto. Specifically, when stripping Before the skinning operation, first adjust the rotation direction and rotation amount of the bidirectional lead screw 303 according to the diameter of the cable to be processed, so that the cable channel spacing between the two friction guide rings 302 matches the cable diameter, start the motor to drive the main shaft 301 to rotate forward, and the friction guide ring 302 rotates synchronously and guides the cable to move forward to the working area of ​​the stripping knife 9, and the stripping knife 9 then cuts the cable surface. During the cutting process, the cable is clamped by a pair of friction guide rings 302 and each elastic clamping member 5 to prevent the wire harness from slipping out from under the stripping knife 9, thereby ensuring stable cutting.

[0038] In a further embodiment of the present invention, the circumcision and peeling mechanism 4 includes an L-shaped bracket 401 slidably mounted on the top of the base 1, and a threading sleeve 402 is fixedly connected to the top of the L-shaped bracket 401. A circumcision knife disc 403 is rotatably mounted on one end of the threading sleeve 402. The center points of the two overlap, and a torsion spring 404 is provided between the two. Specifically, the threading sleeve 402 is internally designed with a channel for the wiring harness to pass through, which is used to guide the cable to pass through and position it in the working area of ​​the circumcision knife disc 403, and each elastic clamping member 5 clamps the wiring harness in the channel. The circumcision knife disc 403 is rotatably mounted at the entrance end of the threading sleeve 402, and its diameter is slightly larger than the outer diameter of the cable to ensure that the wiring harness can pass through. The circular cutting knife disc 403 enters the threading sleeve 402 in the circular cutting and peeling mechanism 4, and can completely cover the cable skin during the rotary cutting process. The blade of the circular cutting knife disc 403 can cut into the cable skin and cut along the circumferential direction when the circular cutting knife disc 403 rotates. The torsion spring 404 between the circular cutting knife disc 403 and the threading sleeve 402 can reset the circular cutting knife disc 403 when there is no external force, and also ensure that it will not rotate or loosen at will when it is not working. Only when the circular cutting operation is required, the driving mechanism connected to the circular cutting knife disc 403 will drive it to rotate. At this time, the torsion spring 404 is compressed, providing the necessary reset force for the circular cutting knife disc 403 after completing the circular cutting.

[0039] In a further embodiment of the present invention, the one-way transmission member 6 includes a transmission shaft 601 rotatably mounted on the base 1, a transmission ring 602 is rotatably sleeved on the driving spindle 301, a circle of ratchet grooves 603 are provided in the transmission ring 602, an elastic lever 304 abutting and cooperating with the ratchet groove 603 is inserted on the driving spindle 301, the transmission ring 602 and the transmission shaft 601 are connected by a belt 605, a transmission gear 606 is fixedly sleeved on the transmission shaft 601, and a driven rack 405 meshing with the transmission gear 606 is fixedly connected to the bottom of the L-shaped bracket 401. Specifically, a circle of ratchet grooves 603 on the inner side of the transmission ring 602 abuts and cooperates with the elastic lever 304 to realize the one-way transmission function. When the driving spindle 301 rotates forward to guide the wiring harness forward, the end of the elastic lever 304 will rise and fall along the inclined surface of the ratchet groove 603. At this time, the transmission ring 602 will not be in contact with the driving spindle 3 01 rotates synchronously, the circular cutting and peeling mechanism 4 will remain in a fixed state when the peeling knife 9 cuts, and when the driving spindle 301 rotates in the opposite direction, the elastic lever 304 extended under the action of elastic force will press against the notch of the column ratchet groove 603, thereby pushing the transmission ring 602 and the driving spindle 301 to rotate synchronously in the same direction, and the belt 605 is connected between the transmission ring 602 and the transmission shaft 601 as a transmission medium. When the transmission ring 602 rotates, the power is transmitted to the transmission shaft 601 through the transmission action of the belt 605, and the transmission gear 606 and the driven rack 405 are always kept in a meshing state. Therefore, when the transmission gear 606 on the transmission shaft 601 rotates, the meshing action between the teeth pushes the driven rack 405 and the L-shaped bracket 401 to move horizontally along the base 1, and the moving direction is exactly opposite to the direction of wire harness extraction, so as to facilitate the rapid separation of the wire core and the skin at the end of the wire harness.

[0040] In a further embodiment of the present invention, an adjusting screw 701 is installed through the thread on the top of the frame 2, and the bottom end of the adjusting screw 701 passes through the lifting and adjusting frame 7 and is installed with an anti-slip nut 702. The adjusting screw 701 is fixedly connected to a limiting ring 703 above the lifting and adjusting frame 7, and a compression spring 704 is installed between the limiting ring 703 and the lifting and adjusting frame 7. A connecting column 705 is installed in the lifting and adjusting frame 7, and the peeling knife 9 is installed on the connecting column 705. Specifically, the compression spring 704 between the limiting ring 703 and the lifting and adjusting frame 7 provides a certain elastic force, so that the lifting and adjusting frame 7 maintains a suitable initial position or reset state at the bottom of the adjusting screw 701 when no external force is applied. At the same time, the compression spring 704 can also alleviate the impact and vibration during the lifting and adjusting process, improve the stability and service life of the system, and the user changes the vertical height of the lifting and adjusting frame 7 on the frame 2 by rotating the adjusting screw 701, thereby adjusting the relative position between the stripping knife 9 and the cable. When it is adjusted to a suitable position, when the cable is guided to the stripping area by the harness guide mechanism 3, the stripping knife 9 performs a cutting operation along the length direction of the cable until the entire stripping process is completed. The installed compression spring 704 allows the lifting and adjusting frame 7 to have a separate rising interval relative to the adjusting screw 701, so as to prevent the stripping knife 9 from causing blade wear due to hard friction when it contacts the metal on the harness.

[0041] In a further embodiment of the present invention, ratchets 305 are fixedly connected to both ends of the driving spindle 301, and an abutment rack 706 is slidably connected to the bottom of the lifting and adjusting frame 7. One side of the abutment rack 706 is unidirectionally meshed with the ratchet 305, and a top spring 707 is installed between the other side of the abutment rack 706 and the lifting and adjusting frame 7. Specifically, the lifting and adjusting frame 7 serves as a supporting structure of the peeling knife 9. When the driving spindle 301 rotates forward, the ratchet 305 on the driving spindle 301 intermittently pushes the abutment rack 706, and the abutment rack 706 moves toward the ratchet 305 under the action of the top spring 707. When the driving spindle 301 rotates forward, the friction guide ring 302 guides the cable forward. The height of the lifting and adjusting frame 7 is the same as the initial adjustment height, and when the driving spindle 301 rotates in the opposite direction, the ratchet 305 on the driving spindle 301 will gradually push up the abutment rack 706 under the meshing action, so as to lift the lifting and adjusting frame 7 to a corresponding height, so that the stripping knife 9 and the wire harness are separated, so that the circumcision and stripping mechanism 4 will not be affected by the stripping knife 9 during the circumcision and stripping operations, and the contact between the wire core and the stripping knife 9 during the wire harness extraction process is avoided. When the ratchet 305 reaches the highest point against the abutment rack 706, if the ratchet 305 continues to rotate, the ratchet teeth on the ratchet 305 will intermittently push the abutment rack 706 to shake off the remaining dandruff on the stripping knife 9.

[0042] In a further embodiment of the present invention, a plurality of circular cutting blades 406 are movably inserted in the circular cutting knife disk 403. The circular cutting knife disk 403 is a disc-shaped structure with a central hole, and its internal space is used to accommodate and support the circular cutting blades 406. A distance adjusting ring 407 is also rotatably sleeved in the circular cutting knife disk 403. A slider 408 is fixedly connected to one side of the circular cutting blade 406. An arc groove 409 for the slider 408 to move is provided on the distance adjusting ring 407. Specifically, the distance adjusting ring 407 rotates coaxially with the circular cutting knife disk 403, and is rotatably sleeved inside the circular cutting knife disk 403. The distance adjusting ring 407 The main function of 7 is to adjust the relative position of the circular cutting blade 406 in the circular cutting disc 403, so as to change the cutting diameter or depth. Since the sliders 408 on each circular cutting blade 406 are respectively located in the corresponding arc grooves 409 on the distance adjusting ring 407, as the distance adjusting ring 407 rotates, the sliders 408 will slide along the path of the arc groove 409, and drive each circular cutting blade 406 to make corresponding adjustments synchronously, so as to flexibly change the cutting diameter or depth of the circular cutting blade 406 to adapt to cables of different diameters and make the distance between each circular cutting blade and the wiring harness the same.

[0043] In a further embodiment of the present invention, a transmission switching assembly 8 is installed in the frame 2, which is located on the moving path of the lifting and adjusting frame 7. When the lifting and adjusting frame 7 lifts up the transmission switching assembly 8, the transmission ring 602 is connected to the distance adjusting ring 407 through the transmission switching assembly 8. Specifically, when the driving spindle 301 rotates forward and carries the wiring harness forward, since the height of the lifting and adjusting frame 7 will not be lifted upward, the transmission ring 602 and the distance adjusting ring 407 are in a disconnected state. At this time, the position of each ring cutting blade 406 will not cause the wiring harness to contact its blade, thereby facilitating the wiring harness to quickly pass through the threading sleeve 402 after being cut by the stripping knife 9. When the driving spindle 301 rotates in the opposite direction and the abutting rack 706 connected to the lifting and adjusting frame 7 is lifted up by the ratchet 305, the transmission switching mechanism is pushed by the lifting and adjusting frame 7 moving upward a certain distance. The lifted transmission switching assembly 8 will allow the transmission ring 602 to drive the distance adjusting ring 407 to rotate, so that the rotational motion of the two is transmitted to each other. Once a transmission connection is established between the transmission ring 602 and the distance adjusting ring 407, the reverse rotation of the driving spindle 301 will be transmitted to the distance adjusting ring 407 through the transmission ring 602. The rotation of the distance adjusting ring 407 will drive the arc groove 409 thereon to move, thereby changing the position of the slider 408 and the circular cutting blade 406. After the circular cutting blade 406 moves toward the center of the circular cutting disc 403, the arc groove 409 is used to push the slider 408 to twist the entire circular cutting disc 403. The staff does not need to adjust the position of the circular cutting blade 406 separately. They only need to control the rotation direction of the driving spindle 301 to achieve the switching of the transmission path and the automatic adjustment of the circular cutting blade 406, so that the device can quickly switch between individual cutting and circular cutting.

[0044] In a further embodiment of the present invention, the transmission switching assembly 8 includes an air storage chamber 801 installed in the frame 2, a toggle frame 802 is inserted through the air storage chamber 801, the top of the toggle frame 802 is located above the connecting column 705, a piston 803 is installed in the air storage chamber 801 of the toggle frame 802, a return spring 804 is installed between the bottom of the toggle frame 802 and the air storage chamber 801, a connecting shaft 805 is rotatably nested on one side of the air storage chamber 801, the connection between the connecting shaft 805 and the air storage chamber 801 is connected to the air storage chamber 801, the outer end of the connecting shaft 805 is frictionally transmitted with the transmission ring 602, and the threading sleeve 402 is rotatably connected to the adjusting gear 41 on one side. 1. A connecting ring 806 is coaxially slidably sleeved on the connecting shaft 805, a transmission belt 807 is installed between the adjusting gear 411 and the connecting ring 806, and a gear ring 412 meshing with the adjusting gear 411 is fixedly connected to one side of the distance adjusting ring 407. Specifically, in the initial state, the gas storage chamber 801 is filled with gas of a certain pressure, and the piston 803 on the toggle frame 802 is at the bottom of the gas storage chamber 801 under the action of the return spring 804. There is a certain gap between the connecting shaft 805 and the transmission ring 602. Even if the driving spindle 301 rotates in the opposite direction, it is not enough to transmit significant power. However, when the lifting and adjusting frame 7 rises with the connecting column 705, the connecting shaft 805 is connected to the transmission ring 602. The column 705 will push the toggle frame 802 to move upward. The movement of the toggle frame 802 causes the piston 803 to compress the gas in the gas storage chamber 801, so that the gas pressure in the gas storage chamber 801 increases, and the force of the gas pressure is transmitted to the connecting shaft 805, so that the connecting shaft 805 moves in the direction of the transmission ring 602. Since there is a friction transmission relationship between the connecting shaft 805 and the transmission ring 602, the rotation of the transmission ring 602 will drive the connecting shaft 805 to rotate together. At the same time, the rotation of the connecting shaft 805 also drives the connecting ring 806 that slides coaxially outside it. The connecting ring 806 transmits power to the adjusting gear 411 through the transmission belt 807, which in turn drives The gear ring 412 and the distance adjusting ring 407 that are meshed with the adjusting gear 411 are driven to rotate, thereby realizing the power transmission of the transmission ring 602 and the distance adjusting ring 407 on the driving main shaft 301, allowing the various cutting blades 406 in the cutting disc 403 to automatically extend and cut the epidermis on the wiring harness, and when the lifting and adjusting frame 7 descends, the connecting column 705 no longer applies thrust to the toggle frame 802. At this time, the reset spring 804 resets the toggle frame 802 and the piston 803 to the initial position, and the air pressure in the air storage chamber 801 is also reduced accordingly, and the connecting shaft 805 retracts and resets again to ensure that the skinning knife 9 can be used alone without being affected by the cutting blade 406.

[0045] In a further embodiment of the present invention, a collar 901 is nested at the center of the peeling knife 9, an elastic block 709 plugged into the collar 901 is horizontally installed on the connecting column 705, a plurality of jacks matching the elastic block 709 are annularly distributed on the inner wall of the collar 901, and a threaded crimping sleeve 710 that presses against the elastic block 709 and the collar 901 in turn is symmetrically sleeved on the connecting column 705. Specifically, a pair of threaded crimping sleeves 710 are symmetrically sleeved on the connecting column 705, which are located on the outer side of the elastic block 709, and the threaded crimping sleeves 710 are symmetrically sleeved on the connecting column 705. The connecting sleeve 710 can press the elastic block 709 and the ring 901 in turn by rotating and tightening, so that the elastic block 709 is inserted into the corresponding position on the ring 901, thereby further strengthening the connection between the stripping knife 9 and the connecting column 705. When the threaded crimping sleeve 710 is unscrewed to loosen the elastic block 709, the elastic block 709 moves outward under the action of elastic force. This design not only improves the stability of the connection, but also can facilitate the adjustment of the installation position of the stripping knife 9, thereby ensuring the sharpness of the blade part of the stripping knife 9 that contacts the wiring harness.

[0046] In a further embodiment of the present invention, the elastic clamping member 5 includes a pressure rod 501 that passes through the threading sleeve 402, the pressure rod 501 is elastically connected to the inner wall of the threading sleeve 402, and one end of the pressure rod 501 is installed with a roller 502 in the threading sleeve 402, and the other end is provided with a guide groove 503 along the axis of the outer side of the threading sleeve 402, and the outer wall of the threading sleeve 402 is slidably connected with a clamping cap 410 adapted to the guide groove 503. Specifically, the friction between the pressure rod 501 and the cable is reduced by the roller 502, so that the cable can be threaded more smoothly, that is, It can effectively clamp the cable without causing damage to it. The outer wall snap-in cap 410 of the wire threading sleeve 402 can slide toward the guide groove 503. The shape and size of the snap-in cap 410 are adapted to the guide groove 503. When the snap-in cap 410 is inserted into the guide groove 503, the position of the pressure rod 501 is restricted to prevent the pressure rod from falling and at the same time prevent the pressure rod from deflecting, thereby ensuring the consistency of the roller orientation. After the snap-in cap 410 is removed from the guide groove 503, the pressure rod 501 can be removed to ensure that the user can easily load and unload the elastic clamp 5.
