Description

Technical Field

[0001] This invention relates to the field of cable processing equipment technology, and in particular to a flexible floating adjustable wire stripping mechanism. Background Technology

[0002] During cable processing, it is usually necessary to strip the outer insulation layer, shielding layer, or sheath layer of the cable to meet the requirements of subsequent welding, crimping, or connection processes.

[0003] Current wire stripping equipment generally uses a fixed cutter head structure, relying on manual adjustment of the cutter position to adapt to the cutting needs of different cable specifications. However, existing technology has the following three main drawbacks: 1. Poor wire diameter adaptability and easy damage to the inner core: Existing equipment mostly uses rigid fixed cutter heads, which makes it difficult to accurately control the cutting depth when processing cables of different diameters or multi-layer structures. It is very easy to damage the internal conductor due to excessive cutting or to fail to peel due to insufficient cutting.

[0004] 2. Poor consistency in stripping length: Traditional equipment usually relies on manual visual positioning or rough setting of distance to control the stripping length, lacking a precise physical limiting structure, resulting in inconsistent stripping lengths of cables produced in batches.

[0005] 3. Complex mechanism adjustment and low processing efficiency: For multi-layer complex cables such as coaxial cables and shielded cables, existing equipment often requires frequent machine stops to change tools or repeatedly adjust the tool holder spacing, which is cumbersome and difficult to meet the requirements of high-efficiency production. Summary of the Invention

[0006] The present invention aims to at least improve one of the technical problems existing in the prior art. To this end, the present invention proposes a flexible floating adjustable wire stripping mechanism.

[0007] The technical solution of the present invention is as follows: A flexible floating adjustable wire stripping mechanism, mounted on a frame, includes: The drive assembly is mounted on the rack; A rotary connecting flange is installed on the output section of the drive assembly; A guide assembly for limiting and introducing the cable, the guide assembly having a guide sleeve fixing bracket, which is mounted on the rotary connection flange; The elastic support structure has a floating tool holder, which is installed at the inlet end of the guide assembly away from the rotary connection flange, and can float and offset radially along the cable under the driving force of the drive assembly. A wire stripping blade, mounted on one side of the floating blade holder, is used for circumferentially cutting the cable; The length limiting component is installed on the guide sleeve fixing frame and the distance between it and the stripping blade is adjustable, which is used to limit the axial feed depth of the cable.

[0008] In one possible technical solution, the guiding component further includes: A guide sleeve is installed at the end of the guide sleeve fixing frame away from the rotary connection flange to serve as the inlet end of the guide assembly, forming a receiving space with the guide sleeve fixing frame. The guide sleeve has a guide hole for the cable to be limited to pass through the guide hole and extend into the receiving space. The guide sleeve has two cavities that are symmetrical about the guide hole.

[0009] In one possible technical solution, there are further two floating tool holders, which are movably connected to the guide sleeve and located in the two cavities of the guide sleeve respectively. Each floating tool holder has a mounting groove on its surface. The elastic support structure also includes: Two elastic elements are respectively installed in each of the mounting slots to provide a deflection preload that brings the two floating tool holders closer to each other.

[0010] In one possible technical solution, the guide sleeve fixing bracket further includes two symmetrically distributed support rods, each support rod having symmetrically positioned adjusting screw holes, and the length limiting component includes: A limiting block is sleeved on the support rod. The limiting block has two wing plates, each wing plate has a strip groove. The limiting block can be locked by a bolt passing through the strip groove and cooperating with the adjusting screw hole, thereby limiting the axial feed depth of the cable.

[0011] In one possible technical solution, the guide sleeve further comprises: The main body has a rectangular cavity with multiple mounting holes on both sides; A crossbeam is installed in the middle of the main body to divide the rectangular cavity into two cavities for mounting a floating knife holder. A guide hole is provided in the middle of the crossbeam for cable to pass through the guide hole and extend into the receiving space.

[0012] In one possible technical solution, the crossbeam further has a slope, and the thickness of the crossbeam gradually decreases along the direction of the receiving space.

[0013] The slope provides clearance for the deflection of the floating blade holder. When the floating blade holder is deflected by the pressure of cables with different outer diameters, it can follow the slope to complete the swing, avoiding rigid collision with the crossbeam. This ensures that the blade holder can adaptively adjust the clamping angle according to the outer diameter of the cable, maintaining stable support for the stripping blade.

[0014] In one possible technical solution, the main body further includes an extension portion with an abutment groove. The abutment groove is disposed opposite to the slope of the crossbeam to deflect the angle of the wire stripping blade, facilitating oblique cutting into the cable.

[0015] In one possible technical solution, the elastic support structure further includes: A pin passes through the floating tool holder and is movably connected to the guide sleeve, used to install the floating tool holder.

[0016] In one possible technical solution, the slope angle is further defined as 5–15°.

[0017] This angle range provides sufficient deflection space for the floating tool holder while ensuring the structural strength of the crossbeam itself. It avoids insufficient thickness in the middle of the crossbeam and reduced support rigidity due to excessive slope angle, thus balancing the structural mechanical performance and the functional requirements of floating adjustment.

[0018] In one possible technical solution, the elastic support component further includes a spring, which is sleeved on the outer periphery of the pin, with one end abutting against the floating blade holder and the other end abutting against the inner wall of the guide sleeve, providing an adaptive deflection elastic support force for the floating blade holder. The elastic force can be automatically adjusted according to the outer diameter of the cable to ensure that the stripping blade always fits against the outer sheath of the cable insulation layer.

[0019] In one possible technical solution, the driving component further includes: A motor mounting bracket is installed on the frame; The drive motor is mounted on the motor mounting base and fixed by the motor end cover pressure block; A motor mounting plate is fixedly connected to the motor mounting base. The motor mounting plate has a through hole for axially restricting the drive motor.

[0020] The elastic floating adjustable wire stripping mechanism according to the present invention has the following beneficial effects: 1. Highly adaptable to various wire diameters, preventing damage to the inner core: By utilizing the elasticity of the spring and the size of the guide hole in the guide sleeve, the mechanism can adapt to different wire diameters. Based on the cooperation between the compression spring and the floating blade holder, it can automatically and elastically fit according to the wire diameter, controlling the cutting depth of the blade and fundamentally reducing the risk of cutting the inner wire core.

[0021] 2. Precise and consistent wire stripping length control: By setting an adjustable limit block in the length limiting component, positioning is achieved by the physical contact between the cable end and the limit block. The operation is intuitive and the limiting is precise, which greatly improves the dimensional consistency of batch wire stripping.

[0022] 3. Simplified structure and convenient operation, facilitating multi-layer stripping: The overall mechanism abandons complex electronic control adjustments, adopting a purely mechanical elastic floating and stop limit logic. For multi-layer cables, simply replacing the guide sleeve, spring, or adjusting stop can quickly achieve graded stripping of the insulation and shielding layers, resulting in low manufacturing costs and easy application.

[0023] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0028] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Example 1 like Figures 1 to 6 As shown, this embodiment provides an elastically floating adjustable wire stripping mechanism, mounted on a frame 100, comprising: The drive assembly is mounted on the rack 100; Rotary connecting flange 2 is installed on the output part of the drive assembly; A guide assembly for limiting and introducing the cable 200, the guide assembly having a guide sleeve fixing bracket 31, which is mounted on the rotary connecting flange 2; The elastic support structure has a floating knife holder 41, which is installed at the inlet end of the guide assembly away from the rotary connecting flange 2, and can float and deflect radially along the cable under the driving force of the drive assembly. The wire stripper 5 is installed on one side of the floating blade holder 41 and is used to circumferentially cut the cable 200. The length limiting component is installed on the guide sleeve fixing frame 31, and the distance between it and the wire stripping blade 5 is adjustable, which is used to limit the axial feed depth of the cable.

[0031] It should be noted that, in this embodiment, the guiding component further includes: The guide sleeve 32 is installed at the end of the guide sleeve fixing frame 31 away from the rotary connecting flange 2, so as to serve as the inlet end of the guide assembly and form a receiving space with the guide sleeve fixing frame 31. The guide sleeve 32 has a guide hole 320 for cable to be limited to pass through the guide hole 320 and extend into the receiving space. The guide sleeve 32 has two cavities that are symmetrical about the guide hole 320.

[0032] It should be noted that in this embodiment, there are two floating tool holders 41, which are movably connected to the guide sleeve 32 and are respectively located in the two cavities of the guide sleeve 32. Each floating tool holder 41 has a mounting groove 410 on its surface. The elastic support structure also includes: Two elastic elements 42 are respectively installed in each of the mounting slots 410 to provide a deflection preload force for the two floating tool holders 41 to move closer to each other. Specifically, the elastic element 42 is a compression spring.

[0033] It should be noted that, in this embodiment, the guide sleeve fixing frame 31 has two symmetrically distributed support rods 310, and the support rods 310 are provided with symmetrically positioned adjusting screw holes 3101. The length limiting component includes: The limiting block 6 is sleeved on the support rod 310. The limiting block 6 has two wing plates 61, and each wing plate 61 has a strip groove 62. The limiting block 6 can be locked by bolts passing through the strip groove 62 and cooperating with the adjusting screw hole 3101, thereby limiting the axial feed depth of the cable.

[0034] It should be noted that, in this embodiment, the guide sleeve 32 includes: The main body 321 has a rectangular cavity and multiple mounting holes on both sides; A crossbeam 322 is installed in the middle of the main body 321 to divide the rectangular cavity into two cavities for installing a floating knife holder 41. A guide hole 320 is provided in the middle of the crossbeam 322 for cable to be limited to pass through the guide hole 320 and extend into the receiving space.

[0035] It should be noted that in this embodiment, the crossbeam 322 has a slope, and the thickness of the crossbeam 322 gradually decreases along the direction of the accommodating space.

[0036] This slope can avoid the elastic floating range of the floating tool holder, and at the same time provide limiting support for the floating tool holder to prevent excessive displacement during the floating process, ensuring that the tool is always aligned with the center of the cable and improving the stability of wire stripping.

[0037] It should be noted that in this embodiment, the main body 321 is provided with an extension 3210, and an abutment groove 3211 is provided on the extension 3210. The abutment groove 3211 is arranged opposite to the slope of the crossbeam 322 and is used to adjust the deflection angle of the wire stripping blade 5 so that it can cut into the cable at an angle.

[0038] This structural design allows the wire stripper blade to maintain the optimal cutting angle when cutting the insulation layer of cables with different diameters, avoiding damage to the cable conductor due to an excessively large cutting angle or failure to effectively cut the insulation layer due to an excessively small cutting angle, thereby further improving the adaptability and processing quality of wire stripping.

[0039] It should be noted that, in this embodiment, the elastic support structure further includes: A pin 43 passes through the floating tool holder 41 and is movably connected to the guide sleeve 32, used to mount the floating tool holder 41. This pin 43 provides a rotation axis for the floating tool holder, ensuring that the floating tool holder can deflect at a certain angle around the pin axis, enabling adaptive angle adjustment in conjunction with the elastic component. The diameter of the pin and the mounting hole on the floating tool holder are fitted with a clearance fit, ensuring smooth rotation of the floating tool holder without jamming or hindering angle adjustment, and also preventing excessive clearance from causing large-scale wobbling during deflection, thus ensuring controllable deflection accuracy.

[0040] It should be noted that in this embodiment, the slope angle is 5 to 15°. This angle range can meet the deflection requirements of the floating blade holder to adapt to cables of different diameters, without compromising the overall structural strength of the crossbeam due to an excessive slope angle. At the same time, it can control the adjustment range of the wire stripping blade within a reasonable range, avoiding excessive deflection angle that would cause the blade to deviate from its cutting position.

[0041] To verify the beneficial effects of the present invention, the following comparative experiment was designed. Control group 1: Traditional rigid fixed veneer cutting machine; Control group 2: Ordinary shearing wire stripper; This invention relates to an elastically floating adjustable wire stripping mechanism.

[0042] Basic experimental conditions: Environment: Room temperature 25±2℃, humidity 45%~55%; Test cable: SYV-75-2-1 coaxial cable, 300 cables per group. Wire stripping was performed, and the stripping data for each group is shown in the table below. Table 1. Comparison of wire stripping effects between the present invention and existing equipment. Comparative analysis shows that this application has the following advantages: ① Significantly improved damage resistance: Compared with traditional rigid rotary cutting, the damage rate of the inner conductor of this mechanism is reduced by 92.6% and the damage rate of the shielding layer is reduced by 96.8%; the shearing process has no elastic adaptive structure, and the extrusion cutting is very easy to damage the internal structure of the cable, and the damage index is much higher than the previous two rotary cutting schemes.

[0043] ②Significant advantage in wire stripping dimensional accuracy: Relying on adjustable physical limit blocks and elastic floating blade holders, the wire stripping length deviation is controlled within 0.12mm, and the dimensional consistency of batch processing is far superior to that of rigid rotary cutting and shearing equipment.

[0044] ③ Optimal stripping and cutting quality: The elastic blade adapts to the outer diameter of the cable, resulting in a smooth circumferential cut without tearing and insulation stripping without residue; the traditional rigid blade head is easily fixed by elasticity, which can lead to insufficient cutting depth and residual insulation. The shearing process relies on extrusion to tear the insulation, resulting in severe burrs and deformation of the cut, with a pass rate of less than half.

[0045] ④ Adaptable to multi-layer cable processing: This mechanism can replace springs with different elastic coefficients to adapt to multi-layer insulation. However, the existing rigid rotary cutting is cumbersome to adjust and the shearing process cannot complete the graded stripping, making it difficult to meet the needs of batch precision processing of coaxial and shielded cables.

[0046] It should be noted that, in this embodiment, the driving component includes: The motor mounting bracket 11 is installed on the frame 100; The drive motor 12 is mounted on the motor mounting base 11 and fixed by the motor end cover pressure block 13; The motor mounting plate 14 is fixedly connected to the motor mounting base 11. The motor mounting plate 14 has a through hole for axially restricting the drive motor 12.

[0047] The elastic floating adjustable wire stripping mechanism according to the present invention has the following beneficial effects: 1. Highly adaptable to various wire diameters, preventing damage to the inner core: By utilizing the elasticity of the spring and the size of the guide hole in the guide sleeve, the mechanism can adapt to different wire diameters. Based on the cooperation between the compression spring and the floating blade holder, it can automatically and elastically fit according to the wire diameter, controlling the cutting depth of the blade and fundamentally reducing the risk of cutting the inner wire core.

[0048] 2. Precise and consistent wire stripping length control: By setting an adjustable limit block in the length limiting component, positioning is achieved by the physical contact between the cable end and the limit block. The operation is intuitive and the limiting is precise, which greatly improves the dimensional consistency of batch wire stripping.

[0049] 3. Simplified structure and convenient operation, facilitating multi-layer stripping: The overall mechanism abandons complex electronic control adjustments, adopting a purely mechanical elastic floating and stop limit logic. For multi-layer cables, simply replacing the guide sleeve, spring, or adjusting stop can quickly achieve graded stripping of the insulation and shielding layers, resulting in low manufacturing costs and easy application.
