Description

Technical Field

[0001] This utility model relates to the field of calibration devices, and in particular to a displacement sensor calibration device. Background Technology

[0002] A displacement sensor calibration device is a tool used to inspect and calibrate displacement sensors. Its main purpose is to determine the accuracy and precision of the displacement sensor, ensuring an accurate relationship between the sensor output value and the actual physical displacement. A displacement sensor is a sensor used to measure the position or change in position of an object. It converts the object's displacement into a corresponding electrical signal or digital data to provide accurate information about the object's position or change in position.

[0003] However, the position of the sensor on some displacement sensor calibration devices cannot be adjusted. This makes it impossible to adjust the sensor with a certain positional offset during the test, which reduces the ease of use of the displacement sensor calibration device, thereby reducing the testing efficiency of the displacement sensor calibration device and the accuracy of the device in detecting displacement sensors.

[0004] Therefore, those skilled in the art have provided a displacement sensor calibration device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a displacement sensor calibration device. Compared to some existing displacement sensor calibration devices, this device features a mounting plate. When the displacement sensor is placed on the mounting plate, the user can adjust the height detected by the sensor by rotating the fourth threaded rod, and then adjust the sensor horizontally by rotating the third threaded rod, thus performing an initial coarse adjustment of the sensor's position. Further, by rotating the third and fourth threaded rods during the first test, a more precise adjustment is made to the displacement sensor, enabling it to accurately detect the standard block. This allows the device to perform more accurate displacement sensor testing and improves the efficiency of the device's displacement sensor testing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a displacement sensor calibration device, comprising a worktable and a standard block. A second support plate is fixedly connected to the rear end of the upper surface of the worktable. Two fixing bolts are threaded into the four corners of the upper surface of the second support plate. A second fixing block is fixedly connected to the middle of one side of the upper surface of the second support plate. A third threaded rod is threaded into the middle of the outer wall of the second fixing block. A second turntable is fixedly connected to the side of the outer wall of the third threaded rod away from the second support plate. A support block is rotatably connected to the side of the outer wall of the third threaded rod close to the second support plate. A second limiting block is fixedly connected to the front and rear ends of the lower part of the outer wall of the support block. A second limiting bolt is threaded into the middle of the upper surface of the second limiting block. A limiting rod is fixedly connected to the front and rear ends of the upper surface of the support block. A fourth threaded rod is rotatably connected to the middle of the upper surface of the support block. A third turntable is fixedly connected to the upper end of the outer wall of the fourth threaded rod. A mounting plate is threaded into the middle of the outer wall of the fourth threaded rod. Multiple mounting grooves are formed in the middle of the upper surface of the mounting plate.

[0007] Compared with existing displacement sensor calibration devices, this displacement sensor calibration device has a first support plate on the slider, allowing the user to replace the standard block by rotating the second threaded rod. This enables the device to test various displacement sensors, thus expanding its applicability. Furthermore, the first limiting block on the clamping plate reduces the possibility of accidental displacement of the standard block during testing, further improving the accuracy of the device's detection.

[0008] Furthermore, a sliding groove is provided in the middle of the upper surface of the worktable, and sliding rods are fixedly connected to both sides of the inner wall of the front end of the sliding groove, and a slider is engaged with the front end of the outer wall of the sliding rod.

[0009] The above technical solution enables the slider to move along the slide bar within the slide groove, carrying the first support plate.

[0010] Furthermore, a first support plate is fixedly connected to the upper surface of the slider, and the four corners of the upper surface of the first support plate are threaded with first fixing bolts;

[0011] The above technical solution enables the first support plate to be fixed to the slider by the first fixing bolt.

[0012] Furthermore, a first fixing block is fixedly connected to both the front end and the rear end of the upper surface of the first support plate, a second threaded rod is threadedly fitted to the middle of the outer wall of the first fixing block, and a first turntable is fixedly connected to the rear end of the outer wall of the second threaded rod.

[0013] The above technical solution enables the user to move the clamping plate by rotating the second threaded rod set on the first fixed block via the first turntable.

[0014] Furthermore, a clamping plate is rotatably connected to the front end of the outer wall of the second threaded rod, and a first limiting block is fixedly connected to both sides of the lower part of the outer wall of the rear end of the clamping plate. A first limiting bolt is threaded in the middle of the upper surface of the first limiting block.

[0015] The above technical solution enables users to limit and fix the position of the first limiting block by rotating the first limiting bolt, thereby limiting and fixing the position of the clamping plate.

[0016] Furthermore, a control console is fixedly connected to the middle of one side of the outer wall of the workbench, and control buttons and a display screen are fixedly connected to the outer wall of the control console on the side away from the workbench.

[0017] The above technical solution enables users to operate the device via control buttons and a display screen on the console.

[0018] Furthermore, each of the four corners of the upper surface of the workbench is fixedly connected with a support leg, and a placement plate is fixedly connected to the middle of the outer wall of the support leg;

[0019] The above technical solution enables users to place the testing tools on the placement plate.

[0020] Furthermore, a drive block is fixedly connected to the front end of the upper surface of the workbench, a cavity is opened at the center of the drive block, a servo motor is fixedly connected to the center of the bottom surface of the cavity, and a first threaded rod is fixedly connected to the output end of the servo motor.

[0021] The above technical solution enables the drive block to drive the first threaded rod via a servo motor, thereby allowing the slider to move on the first threaded rod.

[0023] 1. This utility model proposes a displacement sensor calibration device. Compared with some existing displacement sensor calibration devices, this device is equipped with a mounting plate.

Further, by rotating the third and fourth threaded rods during the first test, a more precise adjustment of the displacement sensor can be made, enabling the displacement sensor to accurately detect the standard block. This allows the device to more accurately detect the displacement sensor and improves the efficiency of displacement sensor testing.

When the displacement sensor is placed on the mounting plate 14, the user can adjust the height detected by the displacement sensor by rotating the fourth threaded rod 34, and then adjust the horizontal direction of the displacement sensor by rotating the third threaded rod 29, thus making an initial rough adjustment of the displacement sensor's position.

[0037] Working principle: When the device is needed, the user first places the appropriate standard block 25 on the first support plate 17 according to the requirements of the displacement sensor. The position of the standard block 25 is limited and fixed by rotating the second threaded rod 20. Then, the position of the standard block 25 is further limited and fixed by rotating the first limiting bolt 24. The displacement sensor is then placed on the mounting plate 14 through the mounting slot 15. The height detected by the displacement sensor is adjusted by rotating the fourth threaded rod 34. The horizontal direction of the displacement sensor is adjusted by rotating the third threaded rod 29, thus making the first rough adjustment of the position of the displacement sensor. During the first test, the displacement sensor is adjusted more precisely by rotating the third threaded rod 29 and the fourth threaded rod 34, so that the displacement sensor can detect the standard block 25 more accurately. Finally, the device is started through the control console 8 for normal testing.
