Description

Technical Field

[0001] This application relates to the technical field of cable preparation, and in particular to a cable preparation traction guiding mechanism. Background Art

[0002] A cable is a connecting component in an electric circuit, mainly responsible for transmitting electrical signals between components. A cable is usually composed of materials such as wires and insulating skins. During the production process of a cable, a traction mechanism is usually required to pull the cable to move, providing traction for the cable to enter different processes for processing.

[0003] In the prior art, there is a traction mechanism, which includes a workbench, a support is fixedly arranged on the workbench, a winding roller is rotatably arranged on the support, a winding motor is fixedly arranged on the side wall of the support, and the driving shaft of the winding motor is coaxially fixed with the winding roller; when pulling a cable, one end of the cable is wound around the winding roller, the winding motor is started, and the winding motor drives the winding roller to rotate, and the traction cable is continuously wound into the winding roller, so as to realize the traction of the cable.

[0004] In the process of implementing this application, it is found that at least the following problems exist in this technology: as the cable is continuously wound on the winding roller, the surface of the winding roller gradually becomes uneven due to the winding of the cable, interfering with the subsequent suspended cable, and the suspended cable lacks restraint when being pulled, resulting in the suspended cable being prone to tremor, affecting processing. Utility Model Content

[0005] In order to improve the guiding property of the cable during the traction movement and reduce the tremor phenomenon of the cable, this application provides a cable preparation traction guiding mechanism.

[0006] The cable preparation traction guiding mechanism provided by this application adopts the following technical solutions:

[0007] A cable preparation traction guiding mechanism includes a workbench, a winding roller is arranged on the workbench, a support frame is vertically and fixedly arranged on the workbench, a restraint cylinder is fixedly arranged at the top of the support frame, the end face of the restraint cylinder faces the winding roller, a plurality of guiding rods are slidably arranged through the circumferential wall of the restraint cylinder, all the guiding rods are perpendicular to the circumferential wall of the restraint cylinder and are evenly spaced in the circumferential direction of the restraint cylinder, and a restraint pressing strip is fixedly arranged at one end of the guiding rod located inside the restraint cylinder; a bundling assembly is further included, and the bundling assembly is used to drive all the guiding rods to slide synchronously.

[0008] By adopting the above technical solution, when the cable is towed, the cable is passed through the center of the restraint cylinder, and one end of the cable is wound around the winding roller; then, all the guide rods are driven by the restraint assembly to synchronously slide into the restraint cylinder, and all the restraint bars approach each other, and the restraint bars restrain the cable from different directions; then, the winding roller is driven to rotate, and the towing cable is continuously wound into the winding roller. Before the cable is wound into the winding roller, it is restrained by the restraint bars, improving the guiding property and stability of the cable during the towing movement, and reducing the tremor phenomenon of the cable.

[0009] Preferably, the restraint assembly includes a deflection disc, a driving rod, and a deflection member. The driving rod is fixedly arranged at one end of the guide rod outside the restraint cylinder. The deflection disc is rotatably arranged on the outer wall of the restraint cylinder. A plurality of restraint chutes are formed on the end wall of the deflection disc. All the restraint chutes are centrosymmetric on the end wall of the deflection disc. Each driving rod correspondingly extends into a restraint chute and is slidably connected with the restraint chute. The deflection member is used to drive the deflection disc to rotate and lock the deflection disc.

[0010] By adopting the above technical solution, when it is necessary to drive all the guide rods to synchronously slide, the deflection disc is driven to rotate by the deflection member. Each restraint chute abuts against a driving rod, so that all the driving rods move synchronously under the action of the restraint chutes, so that all the guide rods move synchronously accordingly. The restraint cylinder restricts the guide rods to slide only in the direction perpendicular to the circumferential wall of the restraint cylinder, thereby driving all the guide rods to synchronously slide.

[0011] Preferably, the deflection member includes a support frame, a worm, and a worm gear ring. The support frame is fixedly arranged on the workbench. The worm is vertically arranged between the support frame and the workbench. The bottom end of the worm is rotatably connected with the workbench, and the top end of the worm is rotatably connected with the support frame. The worm gear ring is fixedly arranged on the circumferential wall of the deflection disc. The worm meshes with the worm gear ring.

[0012] By adopting the above technical solution, when it is necessary to drive the deflection disc to rotate or lock it, the worm is driven to rotate. The worm meshes with the worm gear ring, causing the worm gear ring to rotate. The worm gear ring is fixedly arranged on the circumferential wall of the deflection disc, driving the deflection disc to rotate synchronously, thereby driving the deflection disc to rotate. When the deflection disc has a tendency to rotate, the worm restricts the rotation of the worm gear ring and locks the deflection disc.

[0013] Preferably, the deflection member further includes an adjustment motor. The adjustment motor is fixedly arranged at the top end of the support frame. The drive shaft of the adjustment motor is coaxially fixed with the worm.

[0014] By adopting the above technical solution, the worm is driven to rotate by the adjustment motor, which is convenient for controlling the rotation angle of the worm.

[0015] Preferably, there are four guide rods, two of which are symmetrically arranged in the horizontal direction, and the other two are symmetrically arranged in the vertical direction.

[0016] By adopting the above technical solution, when the winding roller reels the cable, the vibration direction of the cable is mainly divided into two types; one is that the cable is wound around the different axial positions of the winding roller, which will produce horizontal deviation, and the constraint strips set in the horizontal direction are more helpful to reduce the horizontal vibration of the cable; the other is that the cable is continuously wound around the winding roller and thickened, which will produce vertical deviation, and the constraint strips set in the vertical direction are more helpful to reduce the vertical vibration of the cable.

[0017] Preferably, an installation groove is provided on the inner side wall of the restraining pressure strip, and a plurality of guide rollers are rotatably arranged in the installation groove.

[0018] By adopting the above technical solution, when the cable slips, the cable contacts the guide rod, and the guide roller rotates, thereby reducing the friction between the restraining pressure strip and the cable.

[0019] Preferably, an arc-shaped notch is provided in the center of the peripheral surface of the guide roller.

[0020] By adopting the above technical solution, the arc-shaped notch helps to restrict the cable on the guide roller, thereby avoiding the cable from derailing from the guide roller as much as possible.

[0021] Preferably, fixed ear buckles are fixedly provided on the side walls of the workbench, and fixing bolts are provided on the fixed ear buckles.

[0022] By adopting the above technical solution, when the workbench needs to be fixed, the workbench is placed on the corresponding installation ground, the fixing bolts are rotated and tightened, and the fixing ear buckles are fixed, thereby fixing the workbench.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting the support frame, constraint cylinder, guide rod, constraint strip and bunching assembly, the cable is constrained by the constraint strip before being rolled into the winding roller, which improves the guidance and stability of the cable during the traction and movement process and reduces the vibration of the cable;

[0025] 2. By setting a deflection plate, a convergence chute, a driving rod, a support frame, a worm, a worm gear ring, and an adjusting motor, the worm is driven by the adjusting motor to rotate and mesh with the worm gear ring to control the rotation of the deflection plate, and each convergence chute on the deflection plate is against a driving rod, driving all guide rods to slide or lock synchronously;

[0026] 3. By setting the installation groove, guiding roller, and arc-shaped notch, the friction between the restraint strip and the cable is reduced, and the collision interference between adjacent restraint strips when approaching the thin cable is avoided as much as possible; the restraint pressure received by the cable at any position is balanced with each other.

Detailed Description of the Embodiment

[0031] The following Figures 1-3 further describes the present application in detail with reference to the attached drawings.

[0032] An embodiment of the present application discloses a cable preparation traction guiding mechanism. Refer to Figure 1 , which includes a workbench 1. Four fixed ear buckles 13 are fixedly arranged on both sides of the workbench 1, and fixing bolts 131 are arranged on the fixed ear buckles 13. Before use, rotate and tighten the fixing bolts 131 to fix the position of the workbench 1. A winding roller 11 for winding the cable is arranged on the workbench 1. A support frame 12 is vertically and fixedly arranged on the workbench 1, and a restraint cylinder 2 is fixedly arranged at the top of the support frame 12. The end face of the restraint cylinder 2 faces the winding roller 11 directly. When it is necessary to traction the cable, pass the cable through the center of the restraint cylinder 2, and wind one end of the cable on the winding roller 11.

[0033] Refer to Figures 1 to 3, four guide rods 21 penetrate and are slidably arranged on the peripheral wall of the restraint cylinder 2. The four guide rods 21 are all perpendicular to the peripheral wall of the restraint cylinder 2 and are evenly spaced in the circumferential direction of the restraint cylinder 2. Two of the guide rods 21 are symmetrically arranged in the horizontal direction, and the other two guide rods 21 are symmetrically arranged in the vertical direction. A restraint strip 22 is fixedly arranged at one end of the guide rod 21 located inside the restraint cylinder 2. This embodiment further includes a bundling assembly 23, and the bundling assembly 23 is used to drive all the guide rods 21 to slide synchronously. When it is necessary to tow the cable, the bundling assembly 23 drives all the guide rods 21 to slide synchronously into the restraint cylinder 2. The guide rods 21 push all the restraint strips 22 to approach each other, and the cable is pressed against the center of the restraint strip 22 to restrain the cable from different directions.

[0034] To control the synchronous sliding and locking of all the guide rods 21, refer to Figure 1 and Figure 3 , the bundling assembly 23 includes a deflection disk 231, a drive rod 232, and a deflection member 233. The drive rod 232 is fixedly arranged at one end of the guide rod 21 located outside the restraint cylinder 2, and the deflection disk 231 is rotatably arranged on the outer wall of the restraint cylinder 2. Four bundling chutes 2311 are formed on the end wall of the deflection disk 231, and the bundling chutes 2311 are formed along the spiral direction based on the end face of the deflection disk 231. All the bundling chutes 2311 are centrosymmetric on the end wall of the deflection disk 231, and each drive rod 232 correspondingly extends into a bundling chute 2311 and is slidably connected to the bundling chute 2311.

[0035] Refer to Figure 1 and Figure 3 , the deflection member 233 is used to drive the deflection disk 231 to rotate or lock. The deflection member 233 includes a support frame 2331, a worm 2332, a worm gear ring 2333, and an adjustment motor 2334. The support frame 2331 is fixedly arranged on the workbench 1, and the worm 2332 is vertically arranged between the support frame 2331 and the workbench 1. The bottom end of the worm 2332 is rotatably connected to the workbench 1, and the top end of the worm 2332 is rotatably connected to the support frame 2331. The adjustment motor 2334 is fixedly arranged at the top end of the support frame 2331, and the drive shaft of the adjustment motor 2334 is coaxially fixed to the worm 2332. The worm gear ring 2333 is fixedly arranged on the peripheral wall of the deflection disk 231, and the worm 2332 meshes with the worm gear ring 2333.

[0036] Refer to Figure 1 and Figure 3, the worm 2332 is driven to rotate by adjusting the motor 2334, and the worm 2332 and the worm wheel ring 2333 are meshed with each other, driving the deflection plate 231 to rotate. At this time, each convergence chute 2311 is against a driving rod 232, so that all driving rods 232 move synchronously under the action of the convergence chute 2311, driving all guide rods 21 to move synchronously close or away, thereby driving all guide rods 21 to slide synchronously. When the deflection plate 231 has a tendency to rotate, the worm 2332 limits the rotation of the worm wheel ring 2333, locks the deflection plate 231, and the guide rod 21 is also locked.

[0037] In order to reduce the friction between the restraining strip 22 and the cable, refer to Figure 2 and Figure 3 A mounting groove 221 is provided on the inner side wall of the restraining strip 22, and a plurality of guide rollers 222 are rotatably arranged in the mounting groove 221. The guide rollers 222 on the adjacent restraining strips 22 are mutually offset in the axial direction of the restraining tube 2, and the guide rollers 222 on the restraining strips 22 that are arranged opposite to each other are flush with each other in the axial direction of the restraining tube 2. An arc-shaped notch 2221 is provided in the center of the circumference of the guide roller 222. When the cable slips, the cable contacts the guide rod 21, and the guide roller 222 rotates, thereby reducing the friction between the restraining strip 22 and the cable. The arc-shaped notch 2221 helps to restrict the cable on the guide roller 222, and to prevent the cable from being separated from the guide roller 222 as much as possible.

[0038] The implementation principle of a traction guide mechanism for cable preparation in an embodiment of the present application is as follows: when the cable is towed, the cable is passed through the center of the constraint cylinder 2, and one end of the cable is wound around the winding roller 11. Then the adjustment motor 2334 is started, and the adjustment motor 2334 drives the worm 2332 to rotate, and the worm 2332 and the worm wheel engage with each other to drive the deflection disk 231 to rotate and then lock. All the bundling chutes 2311 push all the drive rods 232 to move together, and each drive rod 232 drives the connected guide rod 21 to slide into the constraint cylinder 2. At this time, all the constraint strips 22 are close to each other, and the guide rollers 222 on the constraint strips 22 are against the cables. In this way, the cables are constrained from different directions, the guidance and stability of the cables during the traction and movement process are improved, and the vibration of the cables is reduced.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
