Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sensor technology, and in particular relates to an optical fiber misalignment sensor. Background Technology
[0002] A fiber optic misalignment sensor is a sensor that uses fiber optic technology to detect changes in the position or orientation of an object. It transmits light signals through optical fibers; when an object deviates from a preset path, the light signal changes, thus detecting the misalignment. Currently available fiber optic misalignment sensors typically include a guide rail for mounting the sensor, paired fiber optic sensors, and an amplifier for receiving and transmitting the fiber optic sensor signals. In these existing sensors, the sensor and amplifier are connected by wires. However, when adjusting the sensor position, if the sensor is moved too far, the wires can be pulled and damaged. Utility Model Content

The mounting parts are fixedly mounted to the slider. The fiber optic sensor is also equipped with a fiber optic amplifier, and the fiber optic sensor and the fiber optic amplifier are connected by wires. A distance limiting seat assembly is installed between the fiber optic sensor and the fiber optic amplifier. The distance limiting seat assembly includes a mounting plate, a first mounting seat fixedly mounted on one side of the mounting plate, a second mounting seat and a distance limiting rope being equipped with the first mounting seat, and external threaded caps fixedly mounted at both ends of the distance limiting rope.
[0006] Preferably, both sliders are locked to the mounting rail by bolts installed at the rear of the sliders.
[0007] Preferably, the two fiber optic sensors are arranged facing each other.
[0008] Preferably, one of the external threaded caps passes through the first mounting base and has a limit nut connected to its outer end by a thread, and the other external threaded cap passes through the second mounting base and has a limit nut connected to its outer end by a thread.
[0009] Preferably, the mounting plate is fixedly mounted on one side of the fiber optic amplifier.
[0010] Preferably, the second mounting base is fixedly mounted on the upper part of one of the fiber optic sensors.

[0018] The present invention will now be described in detail with reference to the accompanying drawings, as shown below. Figure 1 As shown, a fiber optic misalignment sensor includes a mounting rail 1, a slider 2 slidably mounted on the upper part of the mounting rail 1, a fiber optic sensor 3 disposed on the upper part of each slider 2, and an integrated mounting part 4 disposed on both sides of each fiber optic sensor 3. The mounting part 4 is fixedly mounted to the slider 2. The fiber optic sensor 3 is also equipped with a fiber optic amplifier 5. The fiber optic sensor 3 and the fiber optic amplifier 5 are connected by wires. A distance limiting seat assembly 6 is installed between the fiber optic sensor 3 and the fiber optic amplifier 5.
[0019] In this implementation plan, in conjunction with the appendix Figure 2As shown, the distance limiting seat assembly 6 includes a mounting plate 61. A first mounting seat 62 is fixedly mounted on one side of the mounting plate 61. A second mounting seat 63 and a distance limiting rope 64 are provided in cooperation with the first mounting seat 62. Both ends of the distance limiting rope 64 are fixedly provided with external threaded caps 65. The user selects the appropriate length of the distance limiting rope 64 according to the length of the wire connecting the fiber optic amplifier 5 and the fiber optic sensor 3, so that the length of the distance limiting rope 64 is less than the length of the wire. The distance limiting rope 64 is connected to the first mounting seat 62 and the second mounting seat 63 through a limiting nut 66 and an external threaded cap 65. When the fiber optic sensor 3 moves, the movement distance of the fiber optic sensor 3 can be limited, avoiding damage to the wire caused by excessive pulling of the fiber optic sensor 3.
[0020] In this embodiment, specifically, both sliders 2 are locked to the mounting guide rail 1 by bolts installed at the rear of the sliders 2.
[0021] In this embodiment, specifically, the two fiber optic sensors 3 are arranged facing each other.
[0022] In this embodiment, specifically, one of the external threaded caps 65 passes through the first mounting base 62 and is threadedly connected to a limit nut 66 at its outer end, and the other external threaded cap 65 passes through the second mounting base 63 and is threadedly connected to a limit nut 66 at its outer end.
[0023] In this embodiment, specifically, the mounting plate 61 is fixedly mounted on one side of the fiber optic amplifier 5.
[0024] In this embodiment, specifically, the second mounting base 63 is fixedly mounted on the upper part of one of the fiber optic sensors 3.
[0025] Working principle
[0026] In this invention, the user adjusts the position of the fiber optic sensor 3 by adjusting the position of the slider 2 on the mounting rail 1. The fiber optic sensor 3 is used to perform deviation detection on the components of the external device, and the detection data is transmitted to the fiber optic amplifier 5 for display, thereby realizing the function of deviation detection.
