Description

Technical Field

[0001] The utility model relates to the technical field of optical cable testing equipment, in particular to an optical cable torsion testing device. Background Art

[0002] Optical cable is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. Optical cable is mainly composed of optical fiber (glass fiber as thin as hair) and plastic protective casing and plastic sheath. Optical cable is a communication line in which a certain number of optical fibers are arranged in a certain way to form a cable core, which is covered with a sheath and some are also covered with an outer sheath to realize the transmission of optical signals. Torsion test on optical cable is an indispensable part for optical cable product quality supervision and inspection agencies and even optical cable manufacturers to grasp the quality of optical cables.

[0003] At present, an optical cable torsion test device includes a set of clamps for clamping and fixing the optical cable, one of which is connected to a power part, and the other clamp is fixed. The power part drives the clamp connected to it to rotate to perform a torsion test on the optical cable. However, most optical cable torsion test devices only have one set of clamps, or multiple sets of clamps, which are used to clamp the optical cable and perform torsion tests at the same time. After the optical cable test is completed, it is necessary to stop the machine, remove the tested optical cable, and then clamp the optical cable to be tested. This process consumes a lot of test time, which reduces the test efficiency. Therefore, an optical cable torsion test device is needed to improve the above-mentioned problem. Utility Model Content

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] Example:

[0032] See also Figure 1-Figure 4 The present embodiment provides an optical cable torsion test device, including a rack 1, an optical cable fixing unit 8, a power piece 3 and a station switching mechanism 9. The optical cable fixing unit 8 includes two groups of optical cable fixing components, which are divided into a first group of optical cable fixing components and a second group of optical cable fixing components. The optical cable fixing component includes two fixing plates 801 symmetrically arranged above and below, and the two fixing plates 801 are rotatably connected to a rotating rod 802. The opposite ends of the two rotating rods 802 are fixedly connected to a cable clamp 803. The power piece 3 is located at the top of the upper rotating rod 802. The power piece 3 is used to drive the rotating rod 802 located at the top to rotate. Preferably, the power piece 3 includes a power motor and a reduction gearbox, and the power motor and the reduction gearbox are matched for transmission. The power piece 3 is in the test station. A torque sensor 11 is also provided on the output shaft of the power piece 3. The station switching mechanism 9 is installed on the top of the rack 1, and the optical cable fixing unit 8 is installed on the station switching mechanism 9. The station switching mechanism 9 is used to The positions of the two groups of optical cable fixing components are switched. When the optical cable is subjected to a torsion test, the optical cable is placed on the optical cable fixing component, and the two ends of the optical cable are clamped and fixed by the two optical cable clamps 803 of the optical cable fixing component. The optical cable is driven to rotate by the power component 3, and the torsion force of the optical cable is detected by the torque sensor 11, which is used to perform a torsion test on the optical cable. After the optical cable test on the optical cable fixing component at the test station is completed, the optical cable fixing unit 8 is moved by the station switching mechanism 9, and the other group of optical cable fixing components is moved to the test station for testing, and the optical cable fixing components after the test are moved to the waiting stations on both sides, which are used to remove the optical cable after the test and clamp the optical cable to be tested again. By switching the two groups of optical cable fixing components back and forth, when the optical cable is tested on one group of optical cable fixing components, the optical cable on the other group of optical cable fixing components can be disassembled and clamped, so that the torsion test device can work continuously, which greatly reduces the test time and improves the test efficiency.

[0033] In this embodiment, if Figure 3 As shown, a support rod 804 is fixedly connected between two fixing plates 801 of the same group of optical cable fixing components to improve the structural stability of the optical cable fixing components, and a connecting plate 805 is fixedly connected between two fixing plates 801 of different groups of optical cable fixing components located on the same horizontal plane, so that the two groups of optical cable fixing components can move synchronously.

[0034] As one method of this embodiment, Figure 3As shown, the workstation switching mechanism 9 includes a fixing seat 901 fixedly connected to the top of the rack platform 1, a motor 902 is fixedly installed on one side of the fixing seat 901, a screw rod 904 is fixedly connected to the output end of the motor 902, both ends of the screw rod 904 are installed on the rack platform 1 through a bearing seat 903, and a connecting sleeve 905 is fixedly connected to the fixing plate 801 under one group of optical cable fixing components, and the connecting sleeve 905 is threadedly sleeved on the outer side of the screw rod 904. The screw rod 904 is driven to rotate by the motor 902, so that the connecting sleeve 905 moves axially along the screw rod 904, thereby adjusting the position of the optical cable fixing unit 8, which is convenient for adjusting and switching the positions of the two optical cable fixing components.

[0035] In this embodiment, if Figure 3 As shown, a second slide rail 906 is fixedly installed on the top of the fixing seat 901 along the length direction, and the fixing plate 801 below the optical cable fixing assembly is slidably connected with the second slide rail 906. When the optical cable fixing assembly moves, the fixing plate 801 below the optical cable fixing assembly slides with the second slide rail 906, thereby improving the stability of the movement of the optical cable fixing assembly.

[0036] When switching between the two sets of optical cable fixing components, it is necessary to separate the power member 3 from the rotating rod 802. In this embodiment, Figure 2 and Figure 4 As shown, the power member 3 is fixedly installed on the mounting seat 2, and a mounting plate 4 is provided at the bottom of the rotating rod 802 located below. A limit member 7 is installed on the top of the mounting plate 4 and the output shaft of the power member 3, and also includes a spacing adjustment mechanism. The spacing adjustment mechanism is used to drive the mounting seat 2 and the mounting plate 4 to move synchronously. The limit member 7 is detachably connected to the rotating rod 802. The spacing adjustment mechanism includes a supporting frame 5 fixedly installed on the top of the rack 1, and a driving member 6 is fixedly connected to the supporting frame 5. The driving member 6 is preferably a double-axis hydraulic cylinder. The mounting seat 2 and one end of the mounting plate 4 extend into the supporting frame 5. The output shafts at both ends of the driving member 6 are fixedly connected to the mounting seat 2 and the mounting plate 4 respectively. The driving member 6 is used to drive the mounting seat 2 and the mounting plate 4 to synchronously approach or move away from each other, thereby connecting and installing or separating the limit member 7 and the rotating rod 802, which is convenient for switching and using two sets of optical cable fixing components.

[0037] In this embodiment, if Figure 2 As shown, first slide rails 10 are vertically installed at both ends of one side of the support frame 5, and the mounting seat 2 and the mounting plate 4 are slidably connected to the first slide rails 10 to improve the stability of the movement of the mounting seat 2 and the mounting plate 4.

[0038] In this embodiment, if Figure 4As shown, the limit member 7 includes a limit rod, and a limit hole 8021 is provided at one end of the rotating rod 802 near the limit rod. The limit hole 8021 and the limit rod are both compatible square structures. The limit rod and the limit hole 8021 are square structures, so that when the limit rod is inserted into the limit hole 8021, the axial rotation of the rotating rod 802 is limited, so that the rotating rod 802 rotates synchronously with the power member 3, and a guide hole 8022 is provided on one side of the limit rod. The guide hole 8022 is located at one end of the limit hole 8021 and is coaxially arranged. The guide hole 8022 is a conical structure. The convenience of the limit rod and the limit hole 8021 when they are matched is improved by setting the guide hole 8022. Even if there is misalignment, the rotating rod 802 is rotated through the conical structure to align the limit rod and the limit hole 8021, thereby improving the convenience of installation.

[0039] Working principle: When in use, place the optical cable on the optical cable fixing assembly, clamp and fix the two ends of the optical cable by the two optical cable clamps 803 of the optical cable fixing assembly, drive the optical cable to rotate by the power member 3, and detect the torsional force of the optical cable by the torque sensor 11, which is used to perform a torsion test on the optical cable. After the optical cable test is completed on the optical cable fixing assembly at the test station, the driving member 6 drives the mounting seat 2 and the mounting plate 4 to move away from each other synchronously, so that the limit member 7 is separated from the rotating rod 802, and then the motor 902 drives the screw rod 904 to rotate, so that the connecting sleeve 905 moves axially along the screw rod 904, thereby adjusting the position of the optical cable fixing unit 8, and adjusting and switching the two optical cable fixings. The position of the assembly, moves another group of optical cable fixing assemblies to the test station for testing, and the optical cable fixing assemblies after the test are moved to the waiting stations on both sides. At this time, the driving member 6 works to drive the mounting seat 2 and the mounting plate 4 to approach each other synchronously, so that the limit rod is inserted into the limit hole 8021, and the axial rotation of the rotating rod 802 is limited. The rotating rod 802 rotates synchronously with the power member 3 to perform a torsion test on the optical cable. The utility model switches back and forth between the two groups of optical cable fixing assemblies. When the optical cable is tested on one group of optical cable fixing assemblies, the optical cable on the other group of optical cable fixing assemblies can be disassembled and clamped, so that the torsion test device can work continuously, which greatly reduces the test time and improves the test efficiency.

[0040] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
