Description

Technical Field

[0001] This invention relates to the field of cable fixing technology, and more specifically, to an adjustable cable fixing clamp device. Background Technology

[0002] In the field of cable processing, especially in the cable cutting process, the stability and adaptability of cable fixing devices directly affect the processing accuracy and the quality of finished products.

[0003] Existing cable clamping devices generally suffer from the following drawbacks: Firstly, traditional clamping devices mostly employ fixed clamping structures, making it difficult to adaptively adjust to cables of different diameters. When dealing with cables of varying thicknesses, frequent clamp replacements or manual adjustments to the clamping position are necessary, which is not only cumbersome but also prone to causing the cable clamping center height to shift during adjustment, affecting the alignment accuracy of subsequent cutting equipment and resulting in cutting dimension deviations. Secondly, the clamping force of existing devices is mostly fixed and cannot be automatically adjusted according to cable thickness: when clamping thick cables, insufficient clamping force can easily lead to slippage; when clamping thin cables, excessive clamping force can cause damage to the outer sheath or internal structure. Furthermore, the rigid contact method of the clamping components in traditional structures cannot simultaneously meet the protection requirements of different cables, significantly limiting processing efficiency and cable yield. Therefore, an adjustable cable clamping device is urgently needed to solve the above problems. Summary of the Invention

[0013] Preferably, a horizontal plate is fixedly connected to one side of the inner wall of the box, and a round hole is opened at the top of the horizontal plate. The threaded rod passes through the inside of the round hole and is rotatably connected to the horizontal plate.

[0014] Preferably, the clamping assembly includes a first clamping roller and a second clamping roller. There are two first clamping rollers, which are arranged in an isosceles triangle with one second clamping roller. A vertical plate is fixedly connected to the top outer wall of the lifting rod. The vertical plate is rotatably connected to the second clamping roller. The first clamping roller is rotatably connected to one end of the clamping arm.

[0015] Preferably, the outer circumferential wall of the first pressing roller is provided with mounting grooves that are evenly spaced and distributed in a circle. A movable shell is slidably connected inside the mounting groove. Springs that are evenly distributed are fixedly connected to one inner wall of the movable shell. The other end of the spring is fixedly connected to one inner wall of the mounting groove. A pressing column is fixedly connected to one end of the movable shell away from the mounting groove. The pressing column is pressed against the outer circumferential wall of the cable body by the spring.

[0016] Preferably, the outer circumferential wall of the plurality of pressing columns is provided with conical grooves, the cross-section of the conical grooves is an isosceles triangle, and the pressing columns provided with conical grooves are distributed in a fan shape on the outer circumferential wall of the first pressing roller.

[0017] Preferably, the gear-changing assembly includes a first rotating shaft fixedly connected to both ends of the first pressing roller, an extension plate fixedly connected to one side outer wall of the clamping arm, the first pressing roller being rotatably connected to the extension plate, a second gear disk fixedly connected to the circumferential outer wall of the first pressing roller, a first gear disk meshing with the circumferential outer wall of the second gear disk, a gear ring meshing with the circumferential outer wall of the first gear disk, and both the first gear disk and the gear ring being rotatably connected to one side outer wall of the extension plate.

[0018] Preferably, toothed rings are fixedly connected to both sides of the housing, and the toothed rings mesh with the gear rings.

[0019] Preferably, annular covers are fixedly connected to the inner walls of both sides of the housing, and the annular covers are fixedly connected to the toothed ring strip.

[0020] The beneficial effects of this invention are:

[0021] This invention provides an adjustable cable clamping device. Through an adjustable assembly, when the cable body needs to be fixed during processing, the operator rotates a handle to rotate a rotating rod. The rotating rod drives a second helical gear to rotate synchronously. Simultaneously, the second helical gear meshes with a first helical gear, transmitting the rotational motion to the first helical gear, which in turn drives a threaded screw to rotate. The threaded screw meshes with a threaded hole in an extension block. Because a guide post is provided on one side of the extension block, the lifting rod moves vertically along a slide formed by the fixing block. The ramps on both sides of the lifting rod move up or down accordingly. The ramp surfaces of the ramps push the transmission rollers to roll. The transmission rollers, through a movable arm, drive the rotating arm to rotate around a second rotating shaft, causing the first clamping roller at the end of the clamping arm to perform a circular motion. At this time, the two first clamping rollers and the second clamping roller on the vertical plate are distributed in an isosceles triangle. Regardless of how the lifting rod is adjusted, the clamping center height formed by the three remains constant, ensuring that the center position of cables of different diameters remains constant when clamped. This provides a precise positioning reference for subsequent cutting processing, avoiding cutting errors caused by center offset.

[0022] The present invention provides an adjustable cable clamping device. Through the clamping assembly and the tooth changing assembly, during the rotation of the clamping arm, the gear ring on the extension plate meshes with the toothed ring strip on the outside of the housing. When the gear ring moves with the clamping arm, it drives the first gear disk to rotate. The first gear disk then meshes with the second gear disk, causing the first pressure roller to rotate around the first rotating shaft. If the cable body diameter is large, after the first pressure roller rotates, the fan-shaped distribution of the pressure columns with conical tooth grooves rotates to the contact position. When the isosceles triangular cross section of the conical tooth groove is in contact with the outer wall of the large cable, the tooth structure can effectively increase the friction force. At the same time, the spring provides elastic clamping force through the movable shell, thereby ensuring that the large diameter cable can still be firmly clamped. Since the outer strength of the large cable sheath is high, the conical tooth groove is not easily damaged.

[0023] If the cable body diameter is small, the tooth-changing assembly drives the first clamping roller to rotate, so that the clamping column without tapered tooth groove on the outer wall of the first clamping roller rotates to the contact position. At this time, the elastic deformation of the spring buffers the clamping force, preventing the thin cable from being deformed due to rigid compression. The clamping column slides in the mounting groove through the movable shell, which can adaptively fit the cable surface with different curvatures, ensuring that the clamping force is evenly distributed.

[0024] This invention provides an adjustable cable clamping device that achieves three functions—"diameter-adaptive clamping, constant center height, and graded clamping force adjustment"—through the mechanical linkage between the adjustment component and the tooth-changing component. Simultaneously, the adjustment component, driven by a lead screw and linked to the ramp block, causes the clamping component to perform circular motion to adapt to different cable diameters, thus maintaining a constant center height for accurate alignment with subsequent processing equipment. Furthermore, the tooth-changing component drives the first pressure roller to rotate via a gear transmission chain, automatically switching between pressure columns with or without conical tooth grooves based on the cable thickness. This ensures secure clamping of thicker cables while preventing damage to thinner cables, thereby improving the stability and yield rate during cable processing and cutting.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0037] Please see Figures 1-8 An adjustable cable clamp device includes a housing 1, and further includes:

[0038] Clamping assembly 4 for clamping and fixing the cable body 2;

[0039] Adjustment component 5; the vertical movement of adjustment component 5 drives clamping component 4 to perform circular motion to clamp and fix cable body 2. Adjustment component 5 includes fixing blocks 508 fixedly connected to the inner walls of both sides of box 1. A slide is formed between the two fixing blocks 508. A lifting rod 507 is slidably connected inside the slide. Inclined blocks 509 are fixedly connected to the outer walls of both sides of the lifting rod 507. Rotating grooves 511 are opened on both sides of box 1. A second rotating shaft 502 is rotatably connected to the inner walls of both sides of the rotating groove 511. A rotating arm 504 is fixedly connected to the outer circumference of the second rotating shaft 502. A clamping arm 501 and a movable arm 505 are fixedly connected to both ends of the rotating arm 504, respectively. A transmission roller 506 is rotatably connected to one end of the movable arm 505. The transmission roller 506 is in rolling connection with the slope surface of the inclined block 509.

[0040] The tooth-changing component 3, used to adjust the clamping force of the clamping component 4, achieves the triple functions of "diameter adaptive clamping, constant center height, and graded adjustment of clamping force" through the mechanical linkage between the adjusting component 5 and the tooth-changing component 3. At the same time, the adjusting component 5 is linked with the inclined block 509 through the screw drive, so that the clamping component 4 makes a circular motion to adapt to different cable diameters, thereby keeping the center height of the clamping component 4 constant, which is convenient for the precise alignment of subsequent processing equipment. The tooth-changing component 3 drives the first pressure roller 401 to rotate through the gear transmission chain, and automatically switches the pressure column 404 with or without conical tooth groove 406 according to the cable thickness, which not only ensures the clamping firmness of thick cables, but also avoids damage to thin cables, thereby improving the fixation stability and yield during cable processing and cutting.

[0041] Base frame 6 is fixedly connected to housing 1.

[0042] Furthermore, rotating rods 516 are rotatably connected to the inner walls of both sides of the housing 1. A second helical gear 515 is fixedly connected to the outer circumference of the rotating rod 516. A first helical gear 514 meshes with the outer circumference of the second helical gear 515. A threaded screw 512 is fixedly connected to the inner circumference of the first helical gear 514. Extension blocks 513 are fixedly connected to both sides of the lifting rod 507. One extension block 513 has a threaded hole that meshes with the threaded screw 512. When the operator turns the handle 503, the rotating rod 516 rotates synchronously and drives the second helical gear 515 to rotate. The second helical gear 515 meshes with the first helical gear 514, and the rotational motion is transmitted to the first helical gear 514, which in turn drives the threaded screw 512 to rotate. The threaded screw 512 and the threaded hole of the extension block 513 form a threaded transmission structure. Combined with the cooperation of the extension block 513 on the other side and the guide post 510, the lifting rod 507 can be precisely controlled to make vertical lifting motion along the slide formed by the fixed block 508. Thus, the rotational motion can be converted into linear motion through the transmission combination of the helical gear and the threaded screw 512, providing a stable power input for the subsequent ramp block 509 to push the transmission roller 506.

[0043] Furthermore, another extension block 513 has a through hole inside, and a guide post 510 is fixedly connected inside the housing 1. The guide post 510 passes through the through hole, and a handle 503 is fixedly connected to one end of the rotating rod 516. The guide post 510 passes through the through hole of the extension block 513, forming a rigid limit on the movement trajectory of the extension block 513, ensuring that the lifting rod 507 can only move in the vertical direction under the drive of the threaded screw 512, avoiding the lifting rod 507 from shifting or rotating due to the radial force during threaded transmission. The handle 503 allows the operator to manually rotate and drive the movement of the entire adjustment assembly 5, making the adjustment process of the cable clamp center height more convenient and controllable.

[0044] Furthermore, a horizontal plate 517 is fixedly connected to the inner wall of one side of the housing 1. A round hole is opened at the top of the horizontal plate 517, and a threaded rod 512 passes through the inside of the round hole. The threaded rod 512 is rotatably connected to the horizontal plate 517. The horizontal plate 517 provides a support point for the threaded rod 512 through the round hole, so that the threaded rod 512 remains horizontal and coaxial during rotation, effectively avoiding bending deformation caused by uneven force, ensuring the accuracy of the lifting rod 507 when moving vertically, and providing reliable reference support for the subsequent circumferential movement of the clamping assembly 4.

[0045] Furthermore, the clamping assembly 4 includes a first clamping roller 401 and a second clamping roller 402. There are two first clamping rollers 401, which are arranged in an isosceles triangle with one second clamping roller 402. A vertical plate 403 is fixedly connected to the top outer wall of the lifting rod 507. The vertical plate 403 is rotatably connected to the second clamping roller 402. The first clamping rollers 401 are rotatably connected to one end of the clamping arm 501. The two first clamping rollers 401 and the second clamping roller 402 form an isosceles triangle clamping structure. When the lifting rod 507 moves the vertical plate 403 up and down, the clamping arm 501 adjusts the position of the first clamping rollers 401 through the circumferential motion of the rotating arm 504. No matter how the lifting rod 507 is adjusted, the clamping center formed by the three always maintains a constant height. This geometric layout ensures that when cables of different diameters are clamped, their center position is always on the same reference plane, providing a stable positioning basis for the precise alignment of the subsequent cutting equipment and effectively avoiding cutting size errors caused by center offset.

[0046] Furthermore, the outer circumferential wall of the first pressure roller 401 is provided with mounting grooves 408 that are evenly spaced and circularly distributed. A movable shell 405 is slidably connected inside the mounting groove 408. Springs 407 that are evenly distributed are fixedly connected to one inner wall of the movable shell 405. The other end of the springs 407 is fixedly connected to one inner wall of the mounting groove 408. A pressure column 404 is fixedly connected to the end of the movable shell 405 away from the mounting groove 408. The pressure column 404 is pressed against the outer circumferential wall of the cable body 2 by the springs 407. The springs 407 inside the mounting groove 408... 07 provides elastic support for the clamping column 404. When the cable diameter changes, the movable shell 405 can slide in the mounting groove 408, causing the clamping column 404 to adaptively conform to the curvature of the cable surface. The buffering effect of the spring 407 can automatically adjust the clamping force according to the cable thickness, thereby providing sufficient clamping force to prevent slippage for thick cables, and reducing rigid compression through elastic deformation for thin cables to avoid damage to the outer sheath or internal structure. This elastic clamping structure ensures that the clamping force is evenly distributed on the cable surface, improving the adaptability of the device to different cables.

[0047] Furthermore, the outer circumferential walls of multiple clamping columns 404 are provided with conical grooves 406. The cross-section of the conical grooves 406 is an isosceles triangle. The clamping columns 404 with conical grooves 406 are distributed in a fan shape on the outer circumferential wall of the first clamping roller 401. The fan-shaped distribution of the conical grooves 406 clamping columns 404 can be switched to the clamping position by rotating the first clamping roller 401. When clamping a thick cable, the isosceles triangular structure of the conical grooves 406 fits against the outer wall of the cable. The toothed surface can significantly increase the friction force. Combined with the elastic clamping force of the spring 407, it ensures that the large-diameter cable is firmly clamped. Since the outer sheath of the thick cable has high strength, the toothed structure of the conical grooves 406 will not damage it. On the contrary, it can enhance the stability of the clamping and solve the problem of insufficient clamping force of traditional fixing devices for thick cables.

[0048] Furthermore, the gear-changing assembly 3 includes a first rotating shaft 306 fixedly connected to both ends of the first pressing roller 401. An extension plate 305 is fixedly connected to one side of the outer wall of the clamping arm 501. The first pressing roller 401 is rotatably connected to the extension plate 305. A second gear disk 307 is fixedly connected to the outer circumference of one of the first pressing rollers 401. A first gear disk 304 meshes with the outer circumference of the second gear disk 307. A gear ring 303 meshes with the outer circumference of the first gear disk 304. Both the first gear disk 304 and the gear ring 303 are rotatably connected to one side of the outer wall of the extension plate 305. When the clamping arm 501 rotates, the extension plate 306... The gear ring 303 on the extension plate 305 meshes with the gear ring 302 on the outer side of the housing 1. As the clamping arm 501 moves in a circular motion, the gear ring 303 drives the first gear disk 304 to rotate, which in turn drives the first pressing roller 401 to rotate around the first rotating shaft 306 through the meshing second gear disk 307. This gear transmission chain forms a linkage mechanism of "automatic gear switching upon diameter detection", which can realize the automatic rotation and switching of the first pressing roller 401 to the corresponding clamping surface (conical groove 406 surface or smooth surface) according to the change of cable diameter, realizing graded adjustment of clamping force, and adapting to cables of different thicknesses without manual intervention.

[0049] Furthermore, toothed ring bars 302 are fixedly connected to both sides of the housing 1. The toothed ring bars 302 mesh with the gear rings 303. The toothed ring bars 302 are fixed to both sides of the housing 1, forming a meshing transmission structure with the gear rings 303. When the clamping arm 501 moves the extension plate 305, the gear rings 303 roll along the toothed ring bars 302. Its rotational motion is transmitted to the first pressure roller 401 through the first gear disk 304 and the second gear disk 307, so that the gear changing assembly 3 and the adjusting assembly 5 form a mechanical linkage. This can convert the change in cable diameter into the rotational motion of the gears, thereby automatically switching the clamping surface of the pressure column 404, realizing the function of "diameter adaptive adjustment of clamping force", and ensuring that the device can maintain a good clamping effect under different working conditions.

[0050] Furthermore, annular covers 301 are fixedly connected to the inner walls on both sides of the housing 1. The annular covers 301 are fixedly connected to the gear ring 302. While fixing the gear ring 302, the annular covers 301 form a protective shell for the gear transmission structure, which can effectively prevent cable debris, dust and other debris generated during the processing from entering the gear meshing gap, and avoid transmission failure caused by foreign objects jamming.

[0051] In summary, with the aid of the above-mentioned technical solution of the present invention, when the cable body 2 needs to be fixed during processing, the operator rotates the handle 503 to drive the rotating rod 516 to rotate. The rotating rod 516 drives the second helical gear 515 to rotate synchronously. At the same time, the second helical gear 515 meshes with the first helical gear 514, thereby transmitting the rotational motion to the first helical gear 514, which in turn drives the threaded screw 512 to rotate. The threaded screw 512 meshes with the threaded hole of the extension block 513. Since the extension block 513 is provided with a guide post 510 on one side (the guide post 510 passes through the through hole of the extension block 513, restricting its rotation), the lifting rod 507 moves vertically along the slide formed by the fixing block 508. Meanwhile, the ramp blocks 509 on both sides of the lifting rod 507 move up or down accordingly. The ramp surface of the ramp block 509 pushes the transmission roller 506 to roll. The transmission roller 506 drives the rotating arm 504 to rotate around the second rotating shaft 502 through the movable arm 505, so that the first pressing roller 401 at the end of the clamping arm 501 makes a circular motion. At this time, the two first pressing rollers 401 and the second pressing roller 402 on the vertical plate 403 are distributed in an isosceles triangle. No matter how the lifting rod 507 is adjusted, the clamping center height formed by the three remains unchanged, ensuring that the center position of the cable body 2 of different diameters is constant when it is clamped, providing a precise positioning reference for subsequent cutting processing and avoiding cutting errors caused by center offset.

[0052] During the rotation of the clamping arm 501, the gear ring 303 on the extension plate 305 meshes with the gear ring 302 on the outer side of the housing 1. When the gear ring 303 moves with the clamping arm 501, it drives the first gear disk 304 to rotate. The first gear disk 304 then meshes with the second gear disk 307, causing the first pressing roller 401 to rotate around the first rotating shaft 306. If the diameter of the cable body 2 is relatively large, after the first pressing roller 401 rotates, the pressing column 404 with conical tooth grooves 406 distributed in a fan shape rotates to the contact position. When the isosceles triangular cross section of the conical tooth groove 406 fits against the outer wall of the thick cable, the tooth structure can effectively increase the friction. At the same time, the spring 407 provides elastic clamping force through the movable shell 405, thereby ensuring that the large-diameter cable can still be firmly clamped. Since the outer strength of the thick cable is high, the conical tooth groove 406 is not easily damaged.

[0053] If the cable body 2 has a small diameter, the tooth-changing assembly 3 drives the first clamping roller 401 to rotate, causing the clamping column 404 without the tapered tooth groove 406 on the outer wall of the first clamping roller 401 to rotate to the contact position. At this time, the elastic deformation of the spring 407 buffers the clamping force, preventing the thin cable from deforming due to rigid compression. The clamping column 404 slides in the mounting groove 408 through the movable shell 405, which can adaptively fit the cable surface with different curvatures, ensuring that the clamping force is evenly distributed. The entire device achieves "diameter adaptive clamping, constant center height, and clamping force" through the mechanical linkage between the adjusting assembly 5 and the tooth-changing assembly 3. The three functions of "gradual adjustment" are as follows: the adjustment component 5 is linked with the inclined block 509 through the screw drive, so that the clamping component 4 makes a circular motion to adapt to different cable diameters, thereby keeping the center height of the clamping component 4 unchanged, which is convenient for the precise alignment of subsequent processing equipment. The gear changing component 3 drives the first pressure roller 401 to rotate through the gear transmission chain, and automatically switches the pressure column 404 with conical groove 406 or without conical groove 406 according to the cable thickness. This ensures the firm clamping of thick cables and avoids damage to thin cables, thereby improving the fixation stability and yield during cable processing and cutting.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
