Description

Technical Field

[0001] This utility model belongs to the field of cable processing technology, and specifically relates to a cable processing positioning device. Background Technology

[0002] Cables are an important component of power systems, typically consisting of several or more conductors twisted together in a rope-like structure. Cables are wrapped with an insulation layer, giving them the characteristics of being internally energized and externally insulated. During cable processing, depending on actual needs, it is sometimes necessary to cut coiled cables to specific lengths so that the ends can be stripped to expose the conductors for subsequent terminal stamping or welding. During cable cutting, the cable usually needs to be positioned to facilitate the cutting operation.

[0003] Existing technologies disclose positioning devices for cable processing, such as the cable processing positioning device disclosed in CN221885599U, which includes a cable positioning platform, support legs, and a slide rail. The inner wall of the cable positioning platform is provided with a slide rail, and a movable frame is installed inside the slide rail. A positioning frame is installed at the top of the movable frame, and a clamping mechanism for fixing cables of different sizes is provided inside the positioning frame. A motor is mounted on one side of the cable positioning platform via a bracket, and the motor output end is connected to one end of a lead screw. The outer wall of the lead screw penetrates the interior of the movable frame. This cable processing positioning device mainly uses a clamping mechanism to clamp and fix the cable. When the cylinder in the clamping mechanism drives the conical block to move upward, the conical block squeezes the rollers on both sides. The movable frame surrounds the fixed frame, causing the mounting frame to fit against the cable body, facilitating the clamping and fixing of cables of different sizes.

[0004] However, the cable processing positioning device disclosed in this patent still has some shortcomings: the reset of its movable frame mainly relies on torsion springs, but the performance of the torsion springs may be reduced due to repeated stretching and compression during use, affecting the reliability of the reset and thus affecting the use of the device; in addition, the clamping mechanism mainly uses arc-shaped blocks and mounting brackets to form the clamping and positioning of the cable, but when clamping a thicker cable, the contact position between the mounting bracket and the cable will be too low, which may result in insufficient clamping force, affecting the clamping effect, or even failing to clamp the cable.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a cable processing positioning device to solve the problems existing in the cable processing positioning device in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A cable processing positioning device, comprising:

[0009] Processing platform;

[0010] A fixed clamping and positioning assembly is fixed in the processing platform.

A mounting block is rotatably connected to each mounting shaft near its end, and the mounting block is fixedly connected to the processing platform.

[0014] The traction clamping and positioning assembly has the same structure as the fixed clamping and positioning assembly. The base of the traction clamping and positioning assembly is fixedly connected to two slides, and two connecting arms are fixedly fixed at intervals on its outer side. The connecting arms pass downward through the processing platform and are fixedly connected to a connecting plate. The connecting plate is fixedly connected to the upper side of the synchronous belt.

[0015] Preferably, the processing platform has a clearance groove corresponding to the connecting arm.

[0016] Preferably, the retaining ring of the traction clamping positioning assembly faces the fixed clamping positioning assembly.

[0017] Preferably, a plurality of guide positioning components are fixedly fixed at intervals on the processing platform on the side of the fixed clamping and positioning assembly away from the traction clamping and positioning assembly. The guide positioning component includes an H-shaped mounting frame, a fixed guide roller rotatably mounted in the middle of the mounting frame, and a floating guide roller located above the fixed guide roller. The fixed guide roller has a first guide groove recessed in the middle of its outer side; the floating guide roller has a second guide groove recessed in the middle of its middle side; and a floating block is rotatably connected to each end of the floating guide roller.

[0018] The mounting frame has receiving grooves on both sides for accommodating the floating block; two guide rods are symmetrically arranged on each side of the mounting frame, the bottom of the guide rods vertically downwards through the floating block and threadedly connected to the mounting frame, and the guide rods slide with the floating block; a spring is sleeved on the guide rod, the bottom of the spring abuts against the floating block and the top of the spring abuts against the top wall of the receiving groove.

[0019] Preferably, the cable processing positioning device further includes a shearing assembly, which is disposed on a processing platform on the side of the fixed clamping positioning assembly near the traction clamping positioning assembly; the shearing assembly includes an upper shearing component and a lower shearing component, the upper shearing component includes an n-shaped fixed frame, an upper shearing cylinder fixed to the top of the fixed frame and with its telescopic end extending vertically downward through the top of the fixed frame, a first fixed plate fixed to the bottom of the telescopic end of the upper shearing cylinder, and a first shearing blade fixed to the bottom of the first fixed plate;

[0020] The lower shearing component includes a lower shearing cylinder fixed to the bottom of the processing platform and having its telescopic end extending vertically upward through the processing platform, a second fixing plate fixed to the top of the telescopic end of the lower shearing cylinder, and a second shearing blade fixed to the top of the second fixing plate.

[0021] Preferably, the length of the second fixing plate is less than the distance between the two slides; when the lower shear cylinder is fully retracted, the top of the second shear blade is lower than the top of the slide.

[0022] Preferably, two limiting rods are symmetrically fixed to the top of the first fixing plate and the bottom of the second fixing plate, and limiting holes corresponding to the limiting rods are opened on the top of the fixing frame and the processing platform.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) When the extension end of the clamping drive cylinder in the fixed clamping positioning assembly and the traction clamping positioning assembly of this utility model extends, the clamping drive cylinder drives the rotating ring to rotate through the connecting shaft. When the rotating ring rotates, it exerts a force on the guide wheel through the arc-shaped limiting groove. At the same time, the sliding groove on the fixed ring and the T-shaped slider guide and slide together. Under the action of the arc-shaped limiting groove and the sliding groove, the inner ends of the clamping claws on multiple T-shaped sliders approach each other along the radial direction of the fixed ring. The inner ends of multiple clamping claws contact the cable respectively, resulting in multiple clamping points. This clamps and positions the cable passing through the fixed cylinder of the traction clamping positioning assembly, and can form a stable and reliable clamping and positioning for cables of different sizes, including thicker cables.

[0025] (2) The present invention is provided with a guide positioning component. When the cable to be cut passes through the first guide groove and the second guide groove on the multiple guide positioning components, the outer diameter of the cable is greater than the distance between the first guide groove and the second guide groove, which in turn lifts the floating guide roller. The floating guide roller drives the floating block to move upward, which in turn further compresses the spring. The spring exerts downward pressure on the floating block. In this way, the fixed guide roller and the floating guide roller cooperate with each other to clamp the cable. Thus, the multiple guide positioning components play a supporting and guiding positioning role for the moving cable.

[0026] (3) The present invention is provided with a traction drive component for moving the traction clamping and positioning component. By moving the traction clamping and positioning component, the cable can be pulled, which facilitates the subsequent cutting of the cable.

[0027] (4) The present invention is provided with a shearing assembly. When the upper shearing cylinder and the lower shearing cylinder in the shearing assembly extend, the extension end of the upper shearing cylinder drives the first fixed plate and the first shearing blade to move downward, and the extension end of the lower shearing cylinder drives the second fixed plate and the second shearing blade to move downward. In this way, the first shearing blade and the second shearing blade move closer to each other and then cut the cable. Attached Figure Description

[0053] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0054] Example

[0055] See appendix Figure 1-18 A cable processing positioning device, comprising:

[0056] Processing platform 10;

[0057] The fixed clamping and positioning assembly 20 is fixed in the processing platform 10. The fixed clamping and positioning assembly 20 includes a base 21, a fixed cylinder 22 integrally formed on the side of the base 21 and extending horizontally (the base 21 has a through hole communicating with the fixed cylinder 22), a rotating ring 23 sleeved on the fixed cylinder 22 and rotatably engaged with it, a fixed ring 24 located outside the rotating ring 23 and fixedly connected to the fixed cylinder 22, and a sliding guide engagement with the fixed ring 24 evenly disposed on the fixed ring 24 and sliding along the radial direction of the fixed ring 24. The system includes multiple T-shaped sliders 25 (six in this embodiment) and a clamping drive cylinder 26 mounted on one side of the base 21. A connecting shaft 231, penetrating the base 21, is vertically fixed at an eccentric position on the inner side of the rotating ring 23. Multiple arc-shaped limiting grooves 232 are evenly distributed on the rotating ring 23 (the inner end of each arc-shaped limiting groove 232 is close to the center, and the outer end is far from the center). A guide wheel 251 is mounted on the inner side of each T-shaped slider 25, and the guide wheel 251 penetrates the fixing ring 24 and extends into the arc-shaped limiting groove 23. The T-shaped slider 25 has a gripping claw 252 fixed on its inner end; the bottom of the gripping drive cylinder 26 is hinged to the base 21 and the telescopic end is hinged to the connecting shaft 231. When the telescopic end of the gripping drive cylinder 26 extends or retracts, the telescopic end of the gripping drive cylinder 26 drives the rotating ring 23 to rotate, and the multiple gripping claws 252 move closer or further away from each other, thereby achieving gripping positioning or release; in this embodiment, the base 21 is provided with an arc-shaped clearance groove 211 corresponding to the connecting shaft 231. It is not difficult to understand here that the arc-shaped clearance groove 211 corresponds to the movement trajectory of the connecting shaft 231 to avoid dryness; a sliding groove 241 corresponding to the T-shaped slider 25 is opened on the outer side of the fixed ring 24, and a straight groove 242 corresponding to the position of the guide wheel 251 is opened on the fixed ring 24 inside the sliding groove 241 so that the guide wheel 251 can pass through the straight groove 242 and enter the arc-shaped limiting groove 232. The straight groove 242 extends along the length of the sliding groove 241 and corresponds to the movement trajectory of the guide wheel 251.

[0058] The traction drive assembly 30 includes two sliding guide rails 31 fixed at intervals on the top of the processing platform 10 and located on the base 21 of the fixed clamping and positioning assembly 20 near the unloading end; a slide block 32 disposed on the sliding guide rails 31 and slidingly guided by the sliding guide rails 31; a first synchronous pulley 33 and a second synchronous pulley 34 disposed at intervals on the bottom of the processing platform 10; a synchronous belt 35 drivingly connecting the first synchronous pulley 33, the second synchronous pulley 34 and a synchronous belt; a mounting shaft 36 fixed in the middle of the first synchronous pulley 33 and the second synchronous pulley 34; and a traction drive motor 37 fixed to the bottom of the processing platform 10 and whose output shaft is fixedly connected to the mounting shaft 36 of the first synchronous pulley 33. A mounting block 38 is rotatably connected to each mounting shaft 36 near its end, and the mounting block 38 is fixedly connected to the processing platform 10.

[0059] The traction clamping and positioning assembly 40 has the same structure as the fixed clamping and positioning assembly 20. Two slide blocks 32 are fixedly connected to the bottom of the base 21 of the traction clamping and positioning assembly 40, and two connecting arms 41 are fixedly fixed at intervals on the outer bottom of the base 21. Each connecting arm 41 passes downwards through the processing platform 10 and is fixedly connected to a connecting plate 42, which is fixedly connected to the upper side of the synchronous belt 35. In this embodiment, a clearance groove 11 corresponding to the connecting arm 41 is provided on the processing platform 10. It is easy to understand that the clearance groove 11 corresponds to the movement trajectory of the connecting arm 41 to avoid interference. The fixing ring 24 of the traction clamping and positioning assembly 40 faces the fixed clamping and positioning assembly 20.

[0060] On the processing platform 10 of the fixed clamping and positioning assembly 20 away from the traction clamping and positioning assembly 40, a plurality of guide positioning assemblies 50 are fixed at intervals. The guide positioning assembly 50 includes an H-shaped mounting frame 51, a fixed guide roller 52 rotatably mounted in the middle of the mounting frame 51, and a floating guide roller 53 located above the fixed guide roller 52. The fixed guide roller 52 has a first guide groove 521 recessed in the middle of its outer side; the floating guide roller 53 has a second guide groove 531 recessed in the middle of its middle side, and a floating block 54 is rotatably connected to each end of the floating guide roller 53. The mounting frame 51 has receiving grooves 511 on both sides for accommodating the floating blocks 54. Two guide rods 55 are symmetrically arranged on each side of the mounting frame 51. The bottom of the guide rod 55 passes vertically downward through the floating block 54 and is threaded to the mounting frame 51 (the bottom of the guide rod 55 has a section of thread), and the guide rod 55 slides with the floating block 54. A spring 56 is sleeved on the guide rod 55, with the bottom of the spring 56 abutting against the floating block 54 and the top of the spring abutting against the top wall of the receiving groove 511.

[0061] A shearing assembly 60 is disposed on the processing platform 10 of the fixed clamping and positioning assembly 20 near the traction clamping and positioning assembly 40. The shearing assembly 60 includes an upper shearing component 61 and a lower shearing component 62. The upper shearing component 61 includes an n-shaped fixing frame 611, an upper shearing cylinder 612 fixed to the top of the fixing frame 611 with its telescopic end extending vertically downward through the top of the fixing frame 611, a first fixing plate 613 fixed to the bottom of the telescopic end of the upper shearing cylinder 612, and a first shearing blade 614 fixed to the bottom of the first fixing plate 613. The lower shearing component 62 includes a lower shearing cylinder 621 fixed to the bottom of the processing platform 10 with its telescopic end extending vertically upward through the processing platform 10, a second fixing plate 622 fixed to the top of the telescopic end of the lower shearing cylinder 621, and a second shearing blade 623 fixed to the top of the second fixing plate 622.

[0062] In this embodiment, the length of the second fixing plate 622 is less than the distance between the two slides 32; when the lower shearing cylinder 621 is fully retracted, the top of the second shearing blade 623 is lower than the top of the slide 32; when the upper shearing cylinder 612 is fully retracted, the bottom of the first shearing blade 614 is higher than the top of the traction clamping and positioning assembly 40 base 21; two limiting rods 615 are symmetrically fixed on the top of the first fixing plate 613 and the bottom of the second fixing plate 622 respectively, and limiting holes 616 corresponding to the limiting rods 615 are opened on the top of the fixing frame 611 and the processing platform 10.

[0063] In addition, in this embodiment, the height of the receiving groove 511 is greater than the height of the floating block 54; the size of the fixing frame 611 is greater than the size of the traction clamping positioning component 40 base 21 so that the traction clamping positioning component 40 base 21 can enter the fixing frame 611.

[0064] In use, the cable to be cut is passed through the first guide groove 521 and the second guide groove 531 on the multiple guide positioning components 50. The outer diameter of the cable is larger than the distance between the first guide groove 521 and the second guide groove 531, thus lifting the floating guide roller 53. The floating guide roller 53 drives the floating block 54 to move upward, further compressing the spring 56 (when the cable is not inserted, the spring 56 is in a compressed state). The spring 56 exerts downward pressure on the floating block 54, thus the fixed guide roller 52 and the floating guide roller 53 cooperate to clamp the cable. It is easy to understand that when the floating block 54 moves up and down, the guide rod 55 guides the floating block 54.

[0065] Initially, the extension and retraction ends of the upper shearing cylinder 612, lower shearing cylinder 621, and clamping drive cylinder 26 are all fully retracted, and the traction clamping positioning assembly 40 is located inside the fixed frame 611. After the cable passes through the fixed cylinder 22 of the fixed clamping positioning assembly 20 and the fixed cylinder 22 of the traction clamping positioning assembly 40, the extension and retraction end of the clamping drive cylinder 26 of the traction clamping positioning assembly 40 is extended. The clamping drive cylinder 26 drives the rotating ring 23 to rotate through the connecting shaft 231. When the rotating ring 23 rotates, it exerts a force on the guide wheel 251 through the arc-shaped limiting groove 232. At the same time, the sliding groove 241 on the fixed ring 24 and the T-shaped slider 25 are guided and slidably engaged. Thus, under the action of the arc-shaped limiting groove 232 and the sliding groove 241, the inner ends of the clamping claws 252 on the multiple T-shaped sliders 25 move closer to each other radially along the fixed ring 24. The cable passing through the fixed cylinder 22 of the traction clamping and positioning assembly 40 is then clamped and positioned. The traction drive motor 37 is then started to rotate forward. The traction drive motor 37 drives the first synchronous pulley 33 to rotate via the mounting shaft 36. The first synchronous pulley 33 drives the synchronous belt 35 and the second synchronous pulley 34 to rotate. The rotation of the synchronous belt 35 generates a rightward pulling force on the connecting plate 42. Under this pulling force, the synchronous belt 35 drives the entire traction clamping and positioning assembly 40 to move to the right (the sliding guide rail 31 and the slide block 32 guide the movement of the traction clamping and positioning assembly 40). The traction clamping and positioning assembly 40 then drives the clamped and positioned cable to move to the right. During this movement, multiple guide positioning components 50 provide support and guidance for the cable. After the traction clamping and positioning assembly 40 has pulled the cable to the right to the appropriate position, the traction drive motor 37 is turned off, and the extension end of the clamping drive cylinder 26 of the fixed clamping and positioning assembly 20 is extended. Similarly, when the telescopic end of the clamping and positioning assembly 20 extends, the inner ends of the multiple clamping claws 252 in the clamping and positioning assembly 20 move closer to each other radially along the fixing ring 24, thereby clamping and positioning the cable in the fixing cylinder 22 of the clamping and positioning assembly 20. Next, the telescopic ends of the upper shearing cylinder 612 and the lower shearing cylinder 621 are extended. The telescopic end of the upper shearing cylinder 612 drives the first fixing plate 613 and the first shearing blade 614 downwards, and the telescopic end of the lower shearing cylinder 621 drives the second fixing plate 622 and the second shearing blade 623 downwards. This causes the first shearing blade 614 and the second shearing blade 623 to move closer together, thus cutting the cable. Then, the telescopic ends of the upper shearing cylinder 612 and the lower shearing cylinder 621 are fully retracted, and the first shearing blade 614 and the second shearing blade 623 move away from each other and return to their initial positions.

[0066] Next, the clamping drive cylinder 26 of the traction clamping and positioning assembly 40 retracts. The clamping drive cylinder 26 drives the rotating ring 23 to rotate via the connecting shaft 231. The inner ends of the clamping claws 252 on the multiple T-shaped sliders 25 move away from each other radially along the fixed ring 24, thereby releasing the clamped and positioned cable. After removing the cut cable, the traction drive motor 37 is started to rotate in the opposite direction. The synchronous belt 35 drives the traction clamping and positioning assembly 40 to move towards the fixed frame 611 and enter the fixed frame 611. The traction drive motor 37 is then turned off, and the end of the cable passes through the fixed cylinder 22 of the traction clamping and positioning assembly 40. The clamping drive cylinder 26 of the traction clamping and positioning component 40 is extended again to clamp and position the cable. Then, the clamping drive cylinder 26 of the fixed clamping and positioning component 20 is retracted, and the multiple clamping claws 252 of the fixed clamping and positioning component 20 release the cable. Then, the traction drive motor 37 is started to rotate in the forward direction to move the traction clamping and positioning component 40. This cycle is repeated to achieve the effects of clamping and positioning the cable, traction and movement of the cable, and shearing the cable.
