Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiber optic sensor technology, specifically to a flexible clamping device for fiber optic sensors. Background Technology
[0002] Fiber optic sensors have been widely used in many fields such as aerospace, petrochemicals, and civil engineering due to their advantages such as resistance to electromagnetic interference, good electrical insulation, high sensitivity, and ability to realize distributed measurement. In the actual application of fiber optic sensors, clamping operations are required to complete installation, debugging, testing, and maintenance. Therefore, it is particularly important to develop a flexible clamping device for fiber optic sensors.
[0003] Referring to CN212391025U, a sensor clamping device includes a lower clamping body, a rotating rod, and a storage body. The outer surface of the lower clamping body is provided with locking teeth, and a storage box is located on the upper part of the lower clamping body. A rotating bolt is located on the upper part of the storage box, and a first slide rail is located on the upper part of the inside of the storage box. This device relates to the technical field of automation equipment, specifically a sensor clamping device. This sensor clamping device, through the arrangement of the storage box, rotating rod, and support rod, forms a structure that can be fixed and disassembled. When the sensor is placed in the storage box, it provides protection during clamping. When the sensor is too large or too small, the rotating rod can be rotated inside the support rod by sliding the sliding plate, thereby rotating the rotating rod out of the storage box, facilitating the replacement of the storage box size. The operation is simple. As can be seen from the above, although this device can be widely used, it is generally not convenient to horizontally adjust the angle of the clamping components, making it difficult to adjust the angle of the sensor components as needed. It is also not convenient for omnidirectional processing of the sensor components, often causing inconvenience to users. Utility Model Content
[0004] The purpose of this invention is to provide a flexible clamping device for fiber optic sensors, which solves the problem that although the device proposed in the background art can be applied well, it is usually not convenient to adjust the angle of the clamping component horizontally, thus making it difficult to adjust the angle of the sensor component as needed and making it difficult to perform all-round processing operations on the sensor component.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible clamping device for fiber optic sensors, comprising a base, a top seat above the base, and support seats installed on both sides of the bottom end of the top seat. The bottom ends of the support seats are fixedly connected to the bottom of the base. A telescopic cylinder is installed on one side of the bottom end of the top seat via a bracket. A rack is installed at one end of the telescopic cylinder. A limiting frame is provided on the bottom end of the top seat on one side of the rack via a bracket. The limiting frame is slidably connected to the rack. A vertical shaft is rotatably installed at the center of the top seat. The bottom end of the vertical shaft extends to the outside of the top seat and is fixed with a gear. The gear meshes with the rack. The top end of the vertical shaft extends to the outside of the top seat and is provided with a disc. A rectangular frame is provided at the center of the top end of the disc. A U-shaped frame is provided above the rectangular frame. Support columns are installed on both sides of the bottom end of the U-shaped frame. The bottom ends of the support columns are fixedly connected to the top end of the rectangular frame. A limiting rod is fixed on the inner wall of the upper end of the U-shaped frame. Movable seats are movably installed on the outer walls on both sides of the limiting rod.
[0006] Preferably, a motor is installed at the center of the top of the rectangular frame, and a rotating shaft is installed at the output end of the motor via a coupling. The top end of the rotating shaft extends to the inside of the U-shaped frame and is fitted with a threaded rod. The motor is configured to drive the threaded rod to rotate.
[0007] Preferably, a nut seat is threadedly installed on the outer wall of the upper end of the threaded rod, and a drive arm is rotatably installed on the outer walls of both sides of the nut seat. The end of the drive arm away from the nut seat is rotatably connected to the outer wall of the movable seat. The drive arm is configured to drive the movable seat to slide on the outer wall of the limiting rod.
[0008] Preferably, each of the movable seats is provided with a silicone clamp on its upper side. A second upper arm is rotatably mounted on the outer wall of each silicone clamp on both sides. A second lower arm is rotatably mounted on the end of each second upper arm away from the silicone clamp. The end of each second lower arm away from the second upper arm is rotatably connected to the outer wall of the movable seat. The arrangement of the second upper arm and the second lower arm allows for the movable placement of the silicone clamp.
[0009] Preferably, a first upper arm is rotatably mounted on the outer wall of the silicone chuck on one side of the second upper arm, and a first lower arm is rotatably mounted on the end of the first upper arm away from the silicone chuck. The end of the first lower arm away from the first upper arm is rotatably connected to the outer wall of the movable seat. The first upper arm and the first lower arm are arranged to allow the silicone chuck to be moved and positioned.
[0010] Preferably, an upper connecting rod is provided below the silicone clamp, and both ends of the upper connecting rod are rotatably connected to the inner wall of the first upper connecting arm. A lower connecting rod is rotatably installed on the inner wall of the first lower connecting arm below the upper connecting rod. A spring is installed on the outer wall between the lower connecting rod and the upper connecting rod. The spring is provided to apply elastic pressure to one end of the silicone clamp.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the flexible clamping device for fiber optic sensors is not only easy to process fiber optic sensor components in all directions to improve the convenience of using the clamping device, but also increases the applicability of the clamping device and reduces the phenomenon of clamping damage to fiber optic sensors during use.
[0012] (1) The rack is driven to move by the telescopic cylinder. Because the rack and gear mesh with each other, the rack drives the vertical shaft to rotate through the gear, and the vertical shaft drives the disc to rotate synchronously. The angle of the clamping component can be adjusted to adjust the horizontal angle of the fiber optic sensor component as needed, which makes it easier to perform all-round processing on the fiber optic sensor component, thereby improving the convenience of using the clamping equipment.
[0013] (2) The motor drives the threaded rod to rotate via the rotating shaft, so that the nut seat slides on the outer wall of the threaded rod. At this time, the nut seat drives the two movable seats to slide towards each other on the outer wall of the limit rod via the drive arm, so as to adjust the distance between the two silicone clamps, thereby making it easier to quickly clamp and fix fiber optic sensors of different thicknesses, thus improving the applicability of the clamping device.
[0014] (3) The spring has good elasticity, and the angle between the first lower arm and the first upper arm can be adjusted by the upper and lower connecting rods. This can adjust the angle of one end of the silicone clamp and make the angle between the second upper arm and the second lower arm change accordingly. Since the silicone clamp has good flexibility, it is easy for the two silicone clamps to flexibly clamp the fiber optic sensor, thereby reducing the phenomenon of clamping damage to the fiber optic sensor when the clamping device is used.

A motor 6 is mounted at the center of the top of the rectangular frame 5. The output end of the motor 6 is mounted with a rotating shaft 9 through a coupling. The top end of the rotating shaft 9 extends to the inside of the U-shaped frame 8 and is mounted with a threaded rod 10.
[0022] In use, the motor 6 is configured to drive the threaded rod 10 to rotate;
[0023] A nut seat 11 is threadedly installed on the outer wall of the upper end of the threaded rod 10. A drive arm 14 is rotatably installed on the outer walls of both sides of the nut seat 11. The end of the drive arm 14 away from the nut seat 11 is rotatably connected to the outer wall of the movable seat 13.
[0024] In use, the drive arm 14 is set so that the movable seat 13 can slide on the outer wall of the limit rod 12.
[0025] A U-shaped frame 8 is provided above the rectangular frame 5. Support columns 7 are installed on both sides of the bottom end of the U-shaped frame 8. The bottom end of the support column 7 is fixedly connected to the top end of the rectangular frame 5. A limit rod 12 is fixed on the inner wall of the upper end of the U-shaped frame 8. Movable seats 13 are movably installed on the outer walls on both sides of the limit rod 12. A silicone chuck 16 is provided above the movable seats 13. A second upper connecting arm 27 is rotatably installed on the outer walls on both sides of the silicone chuck 16. A second lower connecting arm 26 is rotatably installed at the end of the second upper connecting arm 27 away from the silicone chuck 16. The end of the second lower connecting arm 26 away from the second upper connecting arm 27 is rotatably connected to the outer wall of the movable seat 13.
[0026] In use, the second upper arm 27 and the second lower arm 26 are configured to allow for the movable placement of the silicone chuck 16.
[0027] The first upper arm 25 is rotatably mounted on the outer wall of the silicone chuck 16 on one side of the second upper arm 27. The first lower arm 24 is rotatably mounted on the end of the first upper arm 25 away from the silicone chuck 16. The end of the first lower arm 24 away from the first upper arm 25 is rotatably connected to the outer wall of the movable seat 13.
[0028] In use, the first upper connecting arm 25 and the first lower connecting arm 24 are configured to allow the silicone chuck 16 to be moved and positioned.
[0029] Below the silicone chuck 16 is an upper connecting rod 22. Both ends of the upper connecting rod 22 are rotatably connected to the inner wall of the first upper connecting arm 25.

[0030] In use, the spring 21 is used to apply elastic pressure to one end of the silicone clamp 16.
[0031] In this embodiment, the motor 6 first drives the threaded rod 10 to rotate via the shaft 9, causing the nut seat 11 to slide on the outer wall of the threaded rod 10. At this time, the nut seat 11, via the drive arm 14, drives two movable seats 13 to slide towards each other on the outer wall of the limiting rod 12, adjusting the distance between the two silicone clamps 16. This allows for clamping and fixing of fiber optic sensors of different thicknesses. Then, the spring 21, with its good elasticity, adjusts the angle between the first lower connecting arm 24 and the first upper connecting arm 25 via the upper connecting rod 22 and the lower connecting rod 23, thereby adjusting the angle of one end of the silicone clamp 16 and causing the second upper connecting arm 27 to connect with the second lower connecting arm 25. The angle between the arms 26 changes accordingly. Due to the good flexibility of the silicone chuck 16, it is easy for the two silicone chucks 16 to flexibly clamp the fiber optic sensor, thereby reducing the phenomenon of clamping damage to the fiber optic sensor and ensuring the integrity of the fiber optic sensor. Finally, the telescopic cylinder 15 drives the rack 19 to translate, so that the rack 19 drives the vertical shaft 17 to rotate through the gear 18, and the vertical shaft 17 drives the disk 4 to rotate synchronously. The angle of the clamping component can be adjusted to adjust the horizontal angle of the fiber optic sensor component as needed, thereby facilitating all-round processing of the fiber optic sensor component and completing the use of the clamping device.
