[0002] A mechanical sensor is a device that can sense physical mechanical quantities and convert them into electrical signals. It has wide applications in various fields and can measure various mechanical quantities, including but not limited to force, pressure, displacement, acceleration, torque, and vibration.

[0003] To ensure the accuracy and reliability of mechanical sensors in practical applications, a sensor testing platform is typically used to test and calibrate them. The testing platform usually has a fixing mechanism to secure the sensor and ensure stability during the testing process.

[0004] However, conventional testing platform fixing mechanisms can only clamp and fix sensors of a single shape. When encountering sensors of different shapes, the fixing mechanism needs to be disassembled and replaced as a whole, which is very troublesome and wastes too much time and manpower. Therefore, it is necessary to provide a mechanical sensor testing platform to solve the above problems.

Detailed Implementation

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] like Figure 1 As shown, this application provides a mechanical sensor testing platform, including a test bench 1. A second adjustment mechanism 11 is fixedly installed on the upper end of the test bench 1. The second adjustment mechanism 11 is arranged horizontally, and a first adjustment mechanism 2 is arranged vertically on the upper end of the second adjustment mechanism 11. A clamping mechanism 3 is installed on the upper end of the first adjustment mechanism 2. The clamping mechanism 3 is used to clamp the mechanical sensor to ensure the stability of the sensor during testing.

[0035] In this application, the second adjustment mechanism 11 and the first adjustment mechanism 2 are arranged crosswise. The first adjustment mechanism 2 is used to adjust the clamping mechanism 3 vertically, while the second adjustment mechanism 11 is used to adjust the first adjustment mechanism 2 and the clamping mechanism 3 horizontally, thus ensuring the flexibility of the position of the clamping mechanism 3.

[0036] It should be noted that the second adjusting mechanism 11 and the first adjusting mechanism 2 have the same structure and installation method. For ease of understanding, the following explanation will take the first adjusting mechanism 2 as an example.

[0037] The first adjustment mechanism 2 has a base plate 21 installed on the upper end of the second adjustment mechanism 11. A drive motor 22 is fixedly installed on one side of the upper end of the base plate 21, and a stop block 23 is fixedly installed on the other side of the upper end of the base plate 21. In this application, the output shaft of the drive motor 22 is oriented toward the stop block 23, and a screw 24 is fixedly installed on the output shaft of the drive motor 22. The screw 24 is rotatably connected to the stop block 23.

[0038] Meanwhile, a nut 25 is threaded onto the screw 24, and a mounting plate 26 is fixedly installed on the upper end of the nut 25. The clamping mechanism 3 is installed on the mounting plate 26. Therefore, starting the drive motor 22 can drive the screw 24 to rotate, so that the nut 25 drives the mounting plate 26 to move horizontally.

[0039] To ensure the stability of the sliding of the mounting plate 26, two sets of slide rails 27 are fixedly installed on the upper end of the base plate 21. The two sets of slide rails 27 are installed on both sides of the screw 24. At the same time, sliders 28 are fixedly installed on both sides of the lower end of the mounting plate 26. The sliders 28 are slidably connected to the slide rails 27. Therefore, when the mounting plate 26 moves, it will drive the sliders 28 to slide on the slide rails 27.

[0040] like Figures 2-3 As shown, the clamping mechanism 3 has a fixed clamp 31, a baffle 32 is fixedly installed on the upper end of one side of the fixed clamp 31, and a lower arc groove 311 is opened on the side of the upper end of the fixed clamp 31 near the baffle 32. The lower arc groove 311 is set in a semi-cylindrical shape, and a mating groove 312 is opened on the upper end of the side of the fixed clamp 31 away from the baffle 32.

[0041] Meanwhile, a movable clamp 33 is provided above the fixed clamp 31. A mating block 331 is fixedly installed at the lower end of the movable clamp 33. The mating block 331 is slidably connected to the mating groove 312. In this application, an upper arc groove 332 is provided below the end of the movable clamp 33 near the baffle 32. The upper arc groove 332 is set in a semi-cylindrical shape.

[0042] Furthermore, a connecting seat 34 is fixedly installed on the upper end of the mounting plate 26. The connecting seat 34 is located on one side of the fixed clamp 31. The connecting seat 34 has a threaded hole 341, and a threaded shaft 35 is threadedly connected to the threaded hole 341. The threaded shaft 35 is rotatably connected to one side of the movable clamp 33. A handle 36 is fixedly installed on the other end of the threaded shaft 35. Therefore, by rotating the handle 36, the threaded shaft 35 can be moved within the connecting seat 34, thereby moving the movable clamp 33 on the fixed clamp 31. Thus, the cylindrical mechanical sensor is clamped by the lower arc groove 311 and the upper arc groove 332.

[0043] In order to clamp the non-cylindrical force sensor, the movable clamp 33 is fixedly installed on both sides above the end away from the threaded shaft 35. A crossbar 334 is fixedly installed between the two sets of crossbars 333. A fixing member 38 is sleeved on the crossbar 334. A clamping plate 37 is fixedly installed at the lower end of the fixing member 38. The clamping plate 37 is located on one side of the movable clamp 33. It should be noted that under normal conditions, the clamping plate 37 is horizontal with the movable clamp 33.

[0044] Meanwhile, a mating plate 381 is vertically fixed to the upper end of the fastener 38. The mating plate 381 has a hole 382 and an installation hole 335 is provided at the upper end of the movable clamp 33. A bolt 39 is threaded into the installation hole 335. In this application, when the mating plate 381 is parallel to the movable clamp 33, the installation hole 335 and the hole 382 correspond to each other, so that the mating plate 381 is fixed by the bolt 39.

[0045] In summary: When testing a cylindrical sensor, it is placed in the lower arc groove 311, and then the position of the movable clamp 33 is adjusted by the handle 36 to move the upper arc groove 332 above the lower arc groove 311, thereby clamping the cylindrical sensor.

[0046] It should be noted that during the process of clamping the cylindrical shape, the clamping plate 37 may be touched and lifted. Since the clamping force is mainly generated through the upper arc groove 332 and the lower arc groove 311, lifting the clamping plate 37 will not affect the clamping of the cylindrical sensor.

[0047] When testing non-cylindrical sensors, loosen bolt 39 and manually rotate clamp 37 upwards along with fixing member 38, so that mating plate 381 is parallel to movable clamp 33. At this time, hole 382 corresponds to mounting hole 335. Then screw bolt 39 in to make clamp 37 vertical. Then adjust the position of movable clamp 33 to move it closer to baffle 32, thereby clamping and fixing non-cylindrical sensors. Therefore, sensors of different shapes can be clamped and fixed. When clamping sensors of different shapes, there is no need to disassemble and replace the entire fixing mechanism. The operation is simple and saves time and manpower.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
