Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fixture devices, in particular to a sensor electrical performance test fixture. Background Technique
[0002] A sensor electrical performance test fixture is a device used to test the electrical performance of sensors. Sensor electrical performance tests usually require multiple tests to ensure the accuracy and reliability of the test results. During multiple tests of sensor electrical performance, it is usually necessary to fix the sensor in the same position, which can ensure that the sensor is in the same position and state during each test, thereby ensuring the consistency and accuracy of the test results. Fixing the sensor in the same position can prevent the sensor from moving or deforming during each test, affecting the accuracy of the test results. There is a sensor electrical performance test fixture in the prior art, and its technical solution includes a base. A clamping component is arranged on the upper surface of the base. The clamping component includes a deformable clamping plate and a turntable for controlling the movement of the deformable clamping plate. First-level rotating blocks, second-level rotating blocks, and third-level rotating blocks are all slidably installed on the deformable clamping plate.
[0003] In the above working process, since the common shapes of sensors also include rectangles, when the deformable clamping plate clamps the sensor, multiple rotating blocks with different diameters rotate and deform to fit the outer surface of the sensor and fix the sensor. However, it can only fit and clamp sensors with a cylindrical shape and cannot adapt to sensors of other shapes, resulting in a small application range and low practicality. Therefore, we propose a sensor electrical performance test fixture. Summary of the Utility Model

[0028] Embodiment
[0029] As Figures 1-4 As shown, a sensor electrical performance test fixture proposed by the present utility model includes a base 1, and further includes a sliding seat 2 slidably installed in the base 1. A clamping assembly is provided on the sliding seat 2, and the clamping assembly includes a fixing plate 6 fixedly installed on the top of the sliding seat 2.
[0030] Among them, a first chute 101 is opened in the base 1, and a bidirectional screw 3 is rotatably installed in the first chute 101. There are two groups of sliding seats 2, which are symmetrically threadedly connected to both ends of the bidirectional screw 3. One end of the bidirectional screw 3 extending out of the base 1 is fixedly installed with a disc, and a first handle 4 is fixedly installed on the disc. By rotating the first handle 4, the bidirectional screw 3 rotates, thereby driving the sliding seats 2 threadedly connected to the bidirectional screw 3 to move towards each other, thereby realizing clamping and fixing of the sensor.
[0031] In this embodiment, the clamping assembly includes an arc-shaped clamping structure and a rectangular clamping structure. The arc-shaped clamping structure includes arc-shaped plates 5 slidably mounted on both sides of the fixed plate 6. Arc-shaped holes 201 are symmetrically formed in the sliding seat 2. There are two sets of arc-shaped plates 5, which are respectively slidably mounted in the arc-shaped holes 201. A pressing block 15 for positioning is rotatably mounted at the bottom of the arc-shaped plate 5. Second sliding grooves 202 are formed on both sides inside the arc-shaped holes 201. At one end of the bottom of the arc-shaped plate 5, sliding blocks 14 adapted to the shape of the second sliding grooves 202 are fixedly mounted. The sliding blocks 14 are all slidably mounted in the second sliding grooves 202. The position of the arc-shaped plate 5 is adjusted so that the arc-shaped plates 5 are all in contact with the outer surface of the sensor. At this time, the sliding blocks 14 fixedly mounted at the bottom of the arc-shaped plate 5 slide in the second sliding grooves 202.
[0032] Among them, a first lead screw 16 is rotatably mounted at one end of the arc-shaped plate 5. A second handle 17 is fixedly mounted at the top of the first lead screw 16. A threaded hole through which the first lead screw 16 can pass is formed in the sliding block 14. The pressing block 15 is fixedly mounted at the bottom of the first lead screw 16. By rotating the second handle 17, the first lead screw 16 rotates, so that the pressing block 15 fixedly mounted at the bottom of the first lead screw 16 tightly presses against the bottom of the arc-shaped hole 201, realizing the fixation of the arc-shaped plate 5.
[0033] As Figures 2-3 shown, the rectangular clamping mechanism includes an L-shaped plate 7 rotatably mounted above the fixed plate 6. The rectangular clamping structure further includes an extension plate 10 fixedly mounted on the top of the fixed plate 6. A U-shaped plate 11 is hinged to the top of the extension plate 10. An adjusting bolt 12 is provided between the U-shaped plate 11 and the extension plate 10. The L-shaped plate 7 is fixedly mounted on the U-shaped plate 11. A moving plate 8 is slidably mounted on the L-shaped plate 7. By rotating the adjusting bolt 12, the U-shaped plate 11 and the L-shaped plate 7 rotate until the bottom of the L-shaped plate 7 is parallel to the base 1, and then the adjusting bolt 12 is tightened to make the U-shaped plate 11 and the L-shaped plate 7 in a fixed state.
[0034] Furthermore, a rectangular groove 71 is formed on one side of the L-shaped plate 7 away from the U-shaped plate 11. A second lead screw 72 is rotatably mounted in the rectangular groove 71. The moving plate 8 is threadedly connected to the second lead screw 72. One end of the second lead screw 72 extending out of the L-shaped plate 7 is fixedly mounted with a third handle 9. By rotating the third handle 9, the second lead screw 72 rotates, so that the moving plate 8 moves, and the sensor is clamped between the moving plate 8 and the short side of the L-shaped plate 7. Finally, by rotating the first handle 4, the sensor is clamped and fixed, realizing the clamping of sensors with a cylindrical or rectangular shape, expanding the use range of the device, increasing the practicability, and realizing the clamping of sensors with various sizes, thereby further increasing the practicability of the device.
[0035] Finally, rubber pads 13 are fixedly installed on the surfaces of the arc-shaped plate 5, the fixing plate 6, the moving plate, and the L-shaped plate 7 that are in contact with the sensor. The rubber pads 13 are used to increase the friction between the clamping assembly and the sensor, and at the same time can protect the surface of the sensor to prevent the surface of the sensor from being worn during the clamping process.
[0036] Working principle: During the working process of the present utility model, when it is necessary to clamp a cylindrical sensor, the position of the arc-shaped plate 5 is adjusted according to the diameter of the sensor, so that the arc-shaped plate 5 is in contact with the outer surface of the sensor. At this time, the sliding block 14 fixedly installed at the bottom of the arc-shaped plate 5 slides in the second chute 202, and then the second handle 17 is rotated to make the first lead screw 16 rotate, so that the pressing block 15 fixedly installed at the bottom of the first lead screw 16 tightly presses against the bottom of the arc-shaped hole 201, so as to fix the arc-shaped plate 5. The first handle 4 is rotated to make the bidirectional screw 3 rotate, thereby driving the sliding seats 2 threadedly connected to the bidirectional screw 3 to move towards each other, so as to realize the clamping and fixing of the sensor. When it is necessary to clamp a rectangular sensor, the adjusting bolt 12 is rotated to make the U-shaped plate 11 and the L-shaped plate 7 rotate until the bottom of the L-shaped plate 7 is parallel to the base 1, and then the adjusting bolt 12 is tightened to make the U-shaped plate 11 and the L-shaped plate 7 in a fixed state. According to the size of the sensor, the third handle 9 is rotated to make the second lead screw 72 rotate, so that the moving plate 8 moves, so that the sensor is clamped between the moving plate 8 and the short side of the L-shaped plate 7. Finally, the first handle 4 is rotated to clamp and fix the sensor, realizing the clamping of sensors with a cylindrical or rectangular shape at the same time, expanding the use range of the device, increasing the practicability, and realizing the clamping of sensors of various sizes, thereby further increasing the practicability of the device.
