Description

Technical Field

[0001] This invention belongs to the field of cable processing technology, and specifically relates to a fixed tooling for cable processing. Background Technology

[0002] In the field of cable processing, such as cable cutting, insulation stripping, and joint crimping, the positioning, conveying, and clamping of cables are the core prerequisites for ensuring processing accuracy and efficiency. If the tooling does not effectively constrain the cable, it can easily lead to problems such as processing deviation, cable loss, and low operating efficiency.

[0003] While existing sampling and testing devices in daily life meet users' needs to a certain extent, they still have certain shortcomings in use. Specific problems are as follows: Traditional cable clamping often adopts a step-by-step operation mode such as manually tightening screws and individually moving the clamping arms. The clamping action requires manual intervention and cannot be seamlessly connected with the positioning and lifting processes. The long operation interval makes it difficult to adapt to the continuous processing requirements of the production line. In addition, manual operation is prone to problems such as asynchronous closing of the two clamping arms and inconsistent angles, which makes it impossible to constrain the cable in all directions at the processing center point. Radial deviation is prone to occur during processing, affecting the accuracy of key dimensions such as cutting length and stripping depth. Ultimately, this leads to a high scrap rate of cable processing, increasing production costs. Protective fixing fixtures have become the key direction for solving the above-mentioned industry pain points.

[0004] To address the aforementioned problems, this application proposes a fixing fixture for cable processing. Summary of the Invention

[0013] As a preferred embodiment of the cable processing fixture of the present invention, the clamping base is fixed between two sets of connecting hinge seats, and a limiting slide rod is fixed at each of the four bottom corners of the pressure plate. The limiting slide rod is slidably connected in a limiting slide groove opened on the surface of the clamping base.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. Equipped with a positioning component, it eliminates the need for precise alignment during cable insertion, reducing cable insertion resistance and lowering the operational threshold for manual cable threading. It consistently keeps the cable centered in the guide channel, preventing subsequent positioning errors and processing mistakes due to cable deviation. The positioning is flexible and compatible with multiple cable specifications, eliminating the need for component replacement. It allows for synchronous adjustment of the distance between two sets of positioning wheels, maintaining a symmetrical distribution throughout the adjustment process to prevent unilateral deviation. It accurately adapts to various cable diameters, from small to large, significantly reducing tooling changeover time and improving the efficiency of processing multiple cable specifications. After cable insertion, the guide wheels automatically correct any deviation, guiding the cable directly between the positioning wheels. Once the handwheel is adjusted for positioning, the conveyor motor can be started to begin transport. The entire process requires no cable repositioning or additional adjustments to the relative positions of components. During positioning, the positioning wheels slightly contact the cable surface, ensuring secure positioning while preventing excessive compression that could deform or damage the cable insulation.

[0017] 2. Equipped with a lifting component, it achieves seamless coordination with the positioning component and provides precise and stable height support for the clamping component. The entire process requires no additional power source or manual operation of the lifting component. Positioning adjustment and height adjustment are triggered and completed synchronously, avoiding asynchrony caused by step-by-step adjustments of positioning and lifting. This significantly improves the continuity and efficiency of the overall processing flow. The transmission path is precise and controllable, ensuring no deviation in the height adjustment of the clamping component and higher fitting accuracy. The meshing structure of the worm gear and worm wheel has self-locking properties, so even when bearing the weight of the clamping component and cable after adjustment, it will not slide down on its own, ensuring stable height and avoiding sudden sinking of the clamping component during processing, which could lead to processing deviations. It also ensures that the clamping component remains coaxial with the cable in the positioning component after adjustment, preventing uneven cable stress and misalignment of processing points during clamping due to height deviation.

[0018] 3. Equipped with clamping components, it provides stable constraint for cable processing points while balancing processing flexibility and cable safety, offering crucial assurance for cable processing. The cable self-triggered clamping requires no additional operation, maximizing linkage efficiency. Utilizing a self-triggered design with a cable-pressing pressure plate, it achieves seamless connection between lifting and clamping upon reaching the desired position. The entire process is completed synchronously with the height of the clamping components, reducing operational gaps between positioning, lifting, and clamping, significantly improving the overall processing speed. Both sets of clamping plates close simultaneously at the same angle, and their internal arc-shaped grooves fully conform to the cable surface, firmly constraining the cable at the processing center point, preventing radial displacement during processing, and significantly improving dimensional accuracy and finished product yield. Furthermore, the arc-shaped grooves on the clamping plates are equidistantly arranged... The pulleys convert the sliding friction between the clamping plate and the cable into rolling friction between the pulleys and the cable. When the cable needs to be finely adjusted along the conveying direction, the pulleys can rotate synchronously with the cable, reducing friction loss between the cable surface and the clamping plate. This is especially suitable for cables with thin insulation layers, preventing the insulation layer from being scratched or deformed during clamping or fine-tuning. Secondly, the rubber anti-slip pads bonded to the pulley surface can significantly increase the friction with the cable surface. Even when the cable is in a clamped and fine-tuned state, the anti-slip pads can firmly adhere to the cable surface, preventing the cable from slipping or shifting when subjected to processing force. This ensures both clamping firmness and further buffers the clamping force through the softness of the rubber, avoiding scratches caused by direct contact between the pulley's metal surface and the cable. This achieves the dual requirements of firm clamping and cable protection, reducing the cable scrap rate during processing. Attached Figure Description

[0033] The surface of the fixed flip base 506 is rotatably connected to the flip shaft 515 via a bearing bracket.

The inside of the clamping plate 517 is provided with an arc-shaped groove. The pulleys 518 are arranged at equal intervals and fixed in the arc-shaped groove of the clamping plate 517. The surface of the pulleys 518 is bonded with rubber anti-slip pads.

[0034] The working principle and usage process of this invention: The processing base 1 provides a supporting reference for the overall tooling; the processing frame 2 and its internal processing machine provide the main body for cable processing; the tooling guides and transports the cable through the positioning component 3; the height of the clamping component 5 is adjusted by the lifting component 4 to accommodate cables of different specifications; and finally, the clamping component 5 securely fixes the cable processing point. The three components work together to ensure that the cable does not shift or shake during processing. The positioning component 3 guides, positions, and transports the cable. Before processing, the cable is threaded through two sets of guide frames 301. The guide frames 301 contain... The guide seat 302 slides in conjunction with the guide frame 301 via a guide groove. The guide wheel 303 is mounted inside the guide seat 302 via a rotating shaft. When the cable passes between the guide wheels 303, if there is a slight deviation in the cable, it will push the guide wheel 303 to slide the guide seat 302. At this time, the springs 304 at the four corners between the guide seat 302 and the guide frame 301 will generate a reverse elastic force, resetting the guide wheel 303 and always keeping the cable in the center of the guide channel to prevent the cable from shifting during insertion. Depending on the cable diameter, the handwheel 309 can be rotated. The anti-slip texture on the surface of the handwheel 309 can increase the grip friction. To prevent slippage, handwheel 309 drives one set of bidirectional lead screws 307 to rotate. The two sets of bidirectional lead screws 307 form a transmission structure via sprockets and chain 308. When one set of bidirectional lead screws 307 rotates, it synchronously drives the other set of bidirectional lead screws 307 to rotate via chain 308. Sliding blocks 306 are adapted to the sliding groove inside the processing base 1, and the two sets of sliding blocks 306 on the same side of the bottom are threadedly connected to the surface of the bidirectional lead screws 307. When the bidirectional lead screws 307 rotate, they cause the two sets of sliding blocks 306 on the same side to move closer or further apart synchronously, thereby causing the two sets of positioning wheels 305 to synchronously adjust their spacing. The cable positioning and adaptation are completed when the surface of the positioning wheel 305 is slightly in contact with the surface of the cable. After the spacing adjustment is completed, the conveying motor 310 fixed on the surface of one of the sliding blocks 306 is started. The output end of the conveying motor 310 is directly connected to the shaft of one of the positioning wheels 305, which can drive the positioning wheel 305 to rotate. Since the two sets of positioning wheels 305 are in contact with the surface of the cable, the actively rotating positioning wheel 305 drives the cable to move through friction, while the passive side positioning wheel 305 rotates with the cable, realizing stable and uniform cable conveying and providing continuous cable feed for the processing machine operation.

[0035] Furthermore, the lifting assembly 4 achieves height linkage adjustment of the clamping assembly 5. When the bidirectional lead screw 307 in the positioning assembly 3, which adjusts the spacing of the positioning wheels 305, rotates, it drives the worm gear 402 to rotate through the bevel gear pair 403. The worm gear 402 meshes with the worm wheel 404, thereby driving the worm wheel 404 to rotate. The worm wheel 404 is fixed at the end of one set of transmission shafts 405. Both sets of transmission shafts 405 are rotatably connected inside the lifting frame 406, and the transmission gears 407 on the surfaces of the two sets of transmission shafts 405 mesh with each other, ultimately achieving synchronous reverse rotation of the two sets of transmission shafts 405 and transmission gears 407. The two sets of transmission gears 407 mesh with two sets of lifting racks 408 respectively, and the lifting racks 408 are slidably connected in the sliding groove inside the lifting frame 406. When the transmission gears 407 rotate synchronously in opposite directions, they drive the two sets of lifting racks 408 to slide synchronously in the same direction. The top ends of the opposite sides of the two sets of lifting racks 408 are fixed to two sets of push-pull blocks 409. 9 is also slidably connected in the internal groove of the lifting frame 406. Therefore, when the lifting rack 408 slides, it will drive the push-pull block 409 to slide synchronously, thereby driving the push-pull frame 410 fixed to the push-pull block 409 to move. The lifting hinge rod 412 consists of two sets of connecting rods that are hinged to each other. The bottom hinge of the two sets of connecting rods is hinged to the fixed hinge seat 411 fixed to the top of the lifting frame 406, and the middle hinge of the two sets of connecting rods is hinged to the push-pull frame 410. When the push-pull frame 410 moves with the push-pull block 406, the lifting rack 408 slides in the groove inside the lifting frame 406. 9. When sliding, it will push the two sets of connecting rods of the lifting hinge rod 412 to rotate around the central hinge point, so as to raise or lower the lifting hinge rod 412 as a whole. At the same time, the top of the two sets of connecting rods of the lifting hinge rod 412 are fixed with intermeshing linkage gears 414 to ensure that the rotation angle of the two sets of connecting rods is consistent and to avoid deviation. The two sets of linkage gears 414 are hinged to the inside of the connecting hinge seat 413 through the hinge rod, and finally drive the connecting hinge seat 413 to rise and fall synchronously, providing a height adaptation base for the clamping assembly 5.

[0036] Furthermore, the clamping assembly 5 achieves synchronous clamping and protection of the cable processing point. When the pressure plate 502 rises below the cable along with the clamping base 501, the cable will press down on the pressure plate 502. The limiting slide rods 503 at the four corners of the bottom of the pressure plate 502 slide along the limiting slide grooves on the surface of the clamping base 501, ensuring that the pressure plate 502 only moves up and down without lateral displacement. At the same time, the spring 504 wrapped around the surface of the limiting slide rod 503 is compressed, generating a restoring elastic force. When the pressure plate 502 moves down, the push wedge block 505 fixed on its lower surface moves down synchronously. The inclined surface of the push wedge block 505 and the fixed flip base The inclined surfaces of the pressure wedges 507, which are slidably connected to the surface of the fixed flip base 506, are adapted to push the two sets of pressure wedges 507 to slide away from each other along the surface of the fixed flip base 506. The inclined surface of the end of the pressure wedge 507 away from the push wedge 505 abuts against the abutment wheel 509, which is rotatably connected to the end of the swing hinge rod 508. When the pressure wedges 507 slide away from each other, they will push the abutment wheel 509 to move, thereby driving the swing hinge rod 508, which is hinged to the fixed flip base 506, to rotate around the hinge point. At this time, the spring 513 between the swing hinge rod 508 and the fixed flip base 506 is stretched or compressed, generating a reverse restoring force. The end of the swing hinge 508 away from the abutment wheel 509 is hinged to the flip rack 510. When the swing hinge 508 rotates, it drives the flip rack 510 to move. The positioning strips 511 on both sides of the flip rack 510 slide along the inside of the positioning frame 512 fixed on the surface of the fixed flip base 506, ensuring that the flip rack 510 moves only linearly without offset. The flip rack 510 meshes with the flip gear 514 fixed on the surface of the flip shaft 515. When the flip rack 510 moves, it drives the flip gear 514 to rotate, which in turn drives the flip shaft 515 to rotate synchronously. The flip frame 516 is fixed on the surface of the flip shaft 515. The cable will rotate with the rotating shaft 515, eventually causing the clamping plate 517 fixed on the surface of the rotating frame 516 to rotate and close synchronously. The arc-shaped groove inside the clamping plate 517 is adapted to the surface of the cable to achieve all-round clamping of the cable. The pulleys 518 arranged at equal intervals in the arc-shaped groove of the clamping plate 517 allow the cable to slide slightly along the conveying direction while the cable is clamped, such as the feed fine adjustment during processing, to avoid excessive clamping and cable wear. At the same time, the rubber anti-slip pads adhered to the surface of the pulleys 518 can increase the friction with the surface of the cable to ensure a firm clamping and prevent the cable from radially shifting when subjected to processing force.

[0037] It should be noted that after processing, rotating the handwheel 309 in the reverse direction releases the positioning wheel 305 from the cable. The push-pull frame 410 will move downward in the reverse direction, which can lower the entire frame through the lifting hinge 412 and drive the clamping base 501 and the pressure plate 502 to move downward synchronously, thereby relieving the pressure of the cable on the pressure plate 502. Spring 2 504 resets, pushing the pressure plate 502 and the push wedge 505 upward, releasing the push on the pressure wedge 507. Spring 3 513 resets synchronously, pulling the swing hinge 508 to rotate in the reverse direction, driving the flip rack 510 to move in the reverse direction, and then driving the flip frame 516 and the clamping plate 517 to flip and open in the reverse direction through the flip gear 514 and the flip shaft 515, releasing the clamping of the cable, making it easy to take out the cable or continue to transport it.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

[0039] Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this invention shall be included within the scope of protection of this invention.
