Description

Technical Field

[0001] This invention relates to the field of cable processing equipment, and more specifically to a 10kV high-voltage cable stripping device. Background Technology

[0002] With the rapid development of the power industry, the demand for high-voltage cables is increasing. High-voltage cable stripping typically requires high precision and efficiency to ensure cable integrity and safety. Because the cross-sectional shape of a 10kV high-voltage cable is approximately a triangle with rounded corners, existing stripping equipment often suffers from uneven stripping and damage to the cable core when processing 10kV high-voltage cables. These problems severely affect stripping quality and production efficiency.

[0003] Existing high-voltage cable stripping devices, such as the novel medium- and high-voltage cable stripping machine disclosed in Chinese Patent Publication No. CN205335764U and the medium- and high-voltage cable stripping machine disclosed in Chinese Patent Publication No. CN102946073A, have a major drawback: the cross-section of a 10kV high-voltage cable is approximately a triangle with rounded corners, making it impossible to adapt the cutting depth to the shape of the cable's outer surface. Therefore, there is currently no device capable of performing cable stripping with high precision and efficiency.

[0004] In summary, in order to improve the accuracy and efficiency of cable stripping, it is necessary to design a 10kV high-voltage cable stripping device to solve the problems mentioned in the background. Summary of the Invention

[0005] The purpose of this invention is to provide a 10kV high-voltage cable stripping device that can efficiently and accurately strip the outer sheath of a 10kV high-voltage cable while avoiding damage to the cable core.

[0006] The technical solution of the present invention is: a 10kV high-voltage cable stripping device, comprising: a clamping mechanism, a hollow rotating mechanism, a stripping base, a moving mechanism, an adaptive cutting mechanism, and a positioning guide mechanism. The clamping mechanism is connected to one side of the moving mechanism, the hollow rotating mechanism is connected to one side of the stripping base, the stripping base is connected to the slider of the moving mechanism, the adaptive cutting mechanism is connected to the hollow rotating mechanism, and the positioning guide mechanism is connected to both sides of the stripping base.

[0007] Furthermore, the adaptive cutting mechanism includes a cutting mechanism and an adaptive mechanism. The cutting mechanism includes a second mounting plate, a hoop, a brushed motor, a transmission device, a serrated blade, and a cutting depth adjustment plate. The brushed motor is fixedly connected to the second mounting plate using two hoops, and power is transmitted to the serrated blade through the transmission device, driving the serrated blade to rotate at high speed. The cutting depth adjustment plate has an elongated hole in the middle and is mounted on the second mounting plate. The cutting depth adjustment plate can move along the plane of the serrated blade to control the cutting depth of the blade. The adaptive mechanism includes a linear optical axis slider module, a cylindrical pin, a slider sleeve, a first mounting plate, and a telescopic spring. The slider sleeve has a plurality of chutes at one side and is fixedly connected to the first mounting plate at the other side. The linear optical axis slider module is installed in the slider sleeve, has a pin hole at one side and is fixedly connected to the cylindrical pin, and is fixedly connected to the upper part of the second mounting plate at the other side. A telescopic spring is installed between the first mounting plate and the second mounting plate. When there is a bulge on the cable surface, the telescopic spring is compressed; when there is a depression on the cable surface, the telescopic spring resets, driving the linear optical axis of the linear optical axis slider module to move along the slider sleeve, making the cutting depth adjustment plate always fit the cable surface, so as to achieve the adaptability of the cutting mechanism to the irregular surface of the 10 kV high-voltage cable.

[0008] Furthermore, the hollow rotary mechanism includes a circumferential cutting mounting plate, a hollow rotary platform, a reduction gear, and a servo motor. The circumferential cutting mounting plate is in a "convex" shape, has four kidney-shaped holes, is connected to the outer ring of the hollow rotary platform at one side, the other side of the hollow rotary platform is connected to one side of the reduction gear, and the other side of the reduction gear is connected to the servo motor through a coupling.

[0009] Furthermore, the moving mechanism mainly includes a frame, a stepper motor, a coupling, two bearings, a screw-nut mechanism, two linear slide rails, and four sliders. The stepper motor is installed on the frame, and power is transmitted to the screw through the coupling. The two bearings are installed on the frame and arranged at both ends of the screw to play a role in support and reducing friction. The two linear slide rails are symmetrically arranged on both sides of the screw and installed on the frame, and are parallel to the axis of the screw. The four sliders are fixedly connected to the stripping base through bolts and placed on the upper side of the linear slide rails. The moving mechanism is mainly used to achieve the movement of wire stripping.

[0010] Furthermore, the clamping mechanism includes a self-centering bench vice I and a support table. The self-centering bench vice I is fixed at one end of the support table, and the other end of the support table is fixedly connected to the frame in the moving mechanism. This mechanism ensures that the 10 kV high-voltage cable is fixed during the wire stripping process of the wire stripping device.

[0011] Furthermore, the positioning and guiding mechanism includes a clamping and guiding mechanism and a supporting and guiding mechanism. The clamping and guiding mechanism includes a self-centering bench vise II, two support plates, four rolling bearings and two rollers. One end of the support plate is equipped with a roller through two rolling bearings, and the other end of the support plate is fixedly installed on the jaws of the self-centering bench vise II. The two support plates are symmetrically installed. The roller can rotate around its axis, and its surface is provided with an arc-shaped groove, which can be fitted with the surface of the 10kV high-voltage cable. By adjusting the jaws of the self-centering bench vise II, the positioning of the 10kV high-voltage cable can be achieved. The surfaces of the two rollers are fitted with the surface of the 10kV high-voltage cable, and the rotation of the two rollers during the movement can achieve the guiding effect during the cutting process. The supporting and guiding mechanism includes a support frame, a roller and two rolling bearings. The support frame is installed on the left side of the wire stripping base, and a roller is installed above the support frame. The supporting and guiding mechanism supports the 10kV high-voltage cable from below to prevent the cable from sagging and deviating during the cutting process.

[0012] Furthermore, the slider sleeve is provided with a chute, and the chute is distributed in a "rice" shape. The position of the linear cutting chute is parallel to the axis of the cable, the position of the rotary cutting chute is perpendicular to the axis of the cable, and the position of the spiral cutting chute forms a 45° angle with the axis of the cable. The above chutes are all connected with the cylindrical pin to form a moving pair connection, which is used to adjust the cutting angle when the cutting mechanism cuts the 10kV high-voltage cable.

[0013] The advantages of the present invention are as follows: The device can adaptively control the cutting depth according to the change of the outer surface shape of the cable, without damaging the internal conductor of the 10kV high-voltage cable, and improving the wire stripping efficiency and accuracy.

Detailed Implementation Example 1

[0025] Please see Figures 1-7 A 10kV high-voltage cable stripping device includes: a clamping mechanism 1, a hollow rotating mechanism 2, a stripping base 3, a moving mechanism 4, an adaptive cutting mechanism 5, and a positioning guide mechanism 6. The clamping mechanism 1 is connected to one side of the moving mechanism 4, the hollow rotating mechanism 2 is connected to one side of the stripping base 3, the stripping base 3 is connected to the slider 407 of the moving mechanism 4, the adaptive cutting mechanism 5 is connected to the hollow rotating mechanism 2, and the positioning guide mechanism 6 is connected to both sides of the stripping base 3.

[0026] Specifically, the adaptive cutting mechanism 5 includes a cutting mechanism and an adaptive mechanism. The cutting mechanism includes a second mounting plate 506, a hoop 507, a brushed motor 508, a transmission device 509, a serrated blade 510, and a cutting depth adjustment plate 511. Two hoops 507 are used to fixedly connect the brushed motor 508 to the second mounting plate 506, and power is transmitted to the serrated blade 510 through the transmission device 509 to drive the serrated blade 510 to rotate at high speed. The cutting depth adjustment plate 511 has an elongated hole in the middle and is mounted on the second mounting plate 506. The cutting depth adjustment plate 511 can move along the plane of the serrated blade 510 to control the cutting depth of the blade. The adaptive mechanism includes a linear optical axis slider module 505, a cylindrical pin 501, a slider sleeve 502, a first mounting plate 503, and a telescopic spring 504. The slider sleeve 502 has a plurality of chutes at one side and is fixedly connected to the first mounting plate 503 at the other side. The linear optical axis slider module 505 is installed in the slider sleeve 502. One side of the linear optical axis slider module 505 has a pin hole and is fixedly connected to the cylindrical pin 501, and the other side is fixedly connected above the second mounting plate 506. A telescopic spring 504 is installed between the first mounting plate 503 and the second mounting plate 506. When there is a bulge on the surface of the cable, the telescopic spring 504 is compressed; when there is a depression on the surface of the cable, the telescopic spring 504 resets, driving the linear optical axis of the linear optical axis slider module 505 to move along the slider sleeve 502, so that the cutting depth adjustment plate 511 always fits the surface of the cable, for realizing the adaptation of the cutting mechanism to the irregular surface of the 10 kV high-voltage cable.

[0027] Specifically, the hollow rotary mechanism 2 includes a circumferential cutting mounting plate 201, a hollow rotary platform 202, a reduction gear 203, and a servo motor 204. The circumferential cutting mounting plate 201 is in a "convex" shape. Four waist-shaped holes are opened on the circumferential cutting mounting plate 201. One side of the circumferential cutting mounting plate 201 is connected to the outer ring of the hollow rotary platform 202, the other side of the hollow rotary platform 202 is connected to one side of the reduction gear 203, and the other side of the reduction gear 203 is connected to the servo motor 204 through a coupling.

[0028] Specifically, the moving mechanism 4 mainly includes a frame 401, a stepper motor 402, a coupling 403, two bearings 404, a screw-nut mechanism 405, two linear slide rails 406, and four sliders 407. The stepper motor 402 is installed on the frame 401, and power is transmitted to the screw through the coupling 403. Two bearings 404 are installed on the frame 401 and arranged at both ends of the screw to play a role in support and reducing friction. Two linear slide rails 406 are symmetrically arranged on both sides of the screw and installed on the frame 401 and are parallel to the axis of the screw. Four sliders 407 are fixedly connected to the wire stripping base 3 by bolts and placed on the upper side of the linear slide rails 406. The moving mechanism 4 is mainly used to realize the movement of wire stripping.

[0029] Specifically, the clamping mechanism 1 includes a self-centering bench vise 101 and a support table 102. The self-centering bench vise 101 is fixed at one end of the support table 102, and the other end of the support table 102 is fixedly connected to the frame 401 in the moving mechanism 4. This mechanism ensures that the 10 kV high-voltage cable is fixed during the wire stripping process of the wire stripping device.

[0030] Specifically, the positioning and guiding mechanism 6 includes a clamping and guiding mechanism and a support and guiding mechanism. The clamping and guiding mechanism includes a self-centering bench vise 605, two support plates 602, four rolling bearings 603 and two rollers 601. One end of the support plate 602 is equipped with a roller 601 through two rolling bearings 603, and the other end of the support plate 602 is fixedly installed on the jaws of the self-centering bench vise 605. The two support plates 602 are symmetrically installed. The roller 601 can rotate around its axis, and an arc-shaped groove is opened on its surface, which can be fitted with the surface of the 10 kV high-voltage cable. By adjusting the jaws of the self-centering bench vise 605, the positioning of the 10 kV high-voltage cable can be achieved. The surfaces of the two rollers 601 are fitted with the surface of the 10 kV high-voltage cable, and the rotation of the two rollers 601 during the movement can achieve the guiding function during the cutting process. The support and guiding mechanism includes a support frame 604, a roller 601 and two rolling bearings 603. The support frame 604 is installed on the left side of the wire stripping base 3, and a roller 601 is installed above the support frame 604. The support and guiding mechanism supports the 10 kV high-voltage cable from below to prevent the cable from sagging and shifting during the cutting process.

[0031] Specifically, the slider sleeve 502 is provided with a chute, and the chute is distributed in a "rice" shape. The position 7 of the straight cutting chute is parallel to the cable axis, the position 9 of the rotary cutting chute is perpendicular to the cable axis, and the position 8 of the spiral cutting chute forms a 45° angle with the cable axis. The above chutes are all connected with the cylindrical pin 501 to form a moving pair connection, which is used to adjust the cutting angle when the cutting mechanism cuts the 10 kV high-voltage cable. Embodiment 2

[0032] Please refer to Figures 1-8A 10kV high-voltage cable stripping device, using rotary cutting as an example, describes its working principle: First, the 10kV high-voltage cable terminal is passed through the hollow rotating mechanism 2, leaving the required working length. The self-centering vise 101 in the rotating clamping mechanism 1 clamps the 10kV high-voltage cable, simultaneously centering it during clamping. Second, the self-centering vise 605 in the rotating positioning and guiding mechanism 6 ensures that the two rollers 601 are as close as possible to the surface of the 10kV high-voltage cable. After clamping and positioning, the axis of the 10kV high-voltage cable passes as close as possible to the center of the hole in the hollow rotating mechanism 2. Then, based on the required thickness of the outer sheath, armor layer, and inner sheath to be cut, the distance between the cutting depth adjustment plate 511 and the serrated blade 510 in the adaptive cutting mechanism 5 is adjusted so that the serrated blade 510 can precisely cut the thickness of the three layers. After the above preparations are completed, the cylindrical pin 501 is pulled upwards and rotated to a suitable angle to be placed into the slot. When the cylindrical pin 501 in the adaptive mechanism is in the rotary cutting groove position 9 of the slider sleeve 502, the brushed motor 508 in the adaptive cutting mechanism 5 is started to make the saw blade 510 rotate. Then the servo motor 204 of the hollow rotary mechanism 2 is started, which can realize the rotation of the hollow rotary mechanism 2, thus realizing the rotary motion cutting of the 10kV high voltage cable. Example 3

[0033] Please see Figures 1-9 This document describes the working principle of a 10kV high-voltage cable stripping device, using a combination of linear cutting and rotary cutting as an example. The preparatory work has been described in Example 2 and will not be repeated here. After preparation, the cylindrical pin 501 is pulled upwards and rotated to a suitable angle to be placed into the groove. When the cylindrical pin 501 in the adaptive mechanism is at position 7 of the linear cutting groove in the slider sleeve 502, the brushed motor 508 in the adaptive cutting mechanism 5 is activated to rotate the serrated blade 510. Then, the stepper motor 402 in the moving mechanism 4 is activated, enabling the linear movement of the stripping base 3, thus achieving linear cutting of the 10kV high-voltage cable. After the linear cutting reaches the predetermined length, the rotary cutting operation in Example 2 is repeated to complete the stripping of the outer sheath, armor, and inner sheath of the 10kV high-voltage cable. Example 4

[0034] Please see Figures 1-8 , Figure 10This document describes the working principle of a 10kV high-voltage cable stripping device, using a combination of spiral cutting and rotary cutting as an example. The preparatory work has been described in Example 2 and will not be repeated here. After preparation, the cylindrical pin 501 is pulled upwards and rotated to a suitable angle to be placed into the groove. When the cylindrical pin 501 in the adaptive mechanism is at the spiral cutting groove position 8 of the slider sleeve 502, the brushed motor 508 in the adaptive cutting mechanism 5 is activated to rotate the serrated blade 510. Then, the servo motor 204 of the hollow rotating mechanism 2 and the stepper motor 402 of the moving mechanism 4 are activated, enabling the rotation of the hollow rotating mechanism 2 and the linear movement of the stripping base 3, thus achieving spiral cutting of the 10kV high-voltage cable. After spiral cutting to the predetermined length, the rotary cutting operation in Example 2 is repeated to complete the stripping of the outer sheath, armor, and inner sheath of the 10kV high-voltage cable.
