[0021] Figures 1 to 5 As shown, it relates to a device for testing the distance and angle of a sensor, including a device platform 1 and a control box 18. A glass container 17 is placed in the middle of the upper surface of the device platform 1. The glass container 17 is a container for installing a medium, and its material is glass. First linear slide rail bodies 2 are symmetrically fixedly installed at both ends of the upper surface of the device platform 1. First sliders 4 are slidably installed on the tops of the two first linear slide rail bodies 2. Second linear slide rail bodies 5 are fixedly installed on the upper surfaces of the two first sliders 4. The linear slide rail strokes of the two first linear slide rail bodies 2 are 200 mm, which can drive the two sensors to perform Y-axis motion respectively.

[0022] The inner sides of the two second linear guide rail bodies 5 are both slidably mounted with second sliders 6, a main clamping mechanism is mounted on the front of the second slider 6 located on the left side of the glass container 17, and an auxiliary clamping mechanism is mounted on the front of the second slider 6 located on the right side of the glass container 17, wherein the linear guide rail strokes of the two second linear guide rail bodies 5 are 400 mm and 300 mm respectively, thereby being able to drive the two sensors to perform Z-axis motion respectively;

[0023] Specifically, if Figure 1 As shown, the main clamping mechanism includes a third linear slide body 8 fixedly mounted on the front of the second slide block 6, a third slide block 10 is slidably mounted inside the side wall of the third linear slide body 8, a mounting plate 11 is fixedly connected to the front of the third slide block 10, a first angle disc 12 is fixedly mounted on the bottom of the mounting plate 11, a second angle disc 13 is fixedly mounted on one end of the lower surface of the first angle disc 12, specifically, the stroke of the first angle disc 12 and the second angle disc 13 is 360° for coarse adjustment and ±5° for fine adjustment, and a main end clamp 14 is fixedly mounted on one side of the outer surface of the second angle disc 13;

[0024] Among them, the linear slide travel of the third linear slide body 8 is 200mm, which can make the main sensor installed by the main end fixture 14 move in the X-axis direction, and the main end fixture 14 is the installation position of the main sensor, and has the ability to move in the X, Y, and Z axes (the movable travel of the X axis is 178.7mm, the movable travel of the Y axis is 118.3mm, and the movable travel of the Z axis is 277.8);

[0025] Accordingly, if Figure 3 As shown, the auxiliary clamping mechanism includes a connecting rod 16 fixedly mounted on the front of the second slider 6, one end of the connecting rod 16 extends to the inside of the glass container 17, and an auxiliary end clamp 15 is fixedly mounted on one end of the connecting rod 16, and the auxiliary end clamp 15 is the installation position of the corresponding sensor or the auxiliary sensor, and has the ability to move in the Y and Z axes;

[0026] At the same time, if Figure 5 As shown, the main end clamp 14 and the auxiliary end clamp 15 are clamps for installing the sensor, and both can be of any style and shape suitable for clamping the sensor.

[0027] A first stepper motor 3 is fixedly mounted on one end of each of the two first linear slide rail bodies 2, and the two first stepper motors 3 are respectively located at the front side of the two first linear slide rail bodies 2; a second stepper motor 7 is fixedly mounted on one end of each of the two second linear slide rail bodies 5, and the two second stepper motors 7 are respectively located at the top of the two second linear slide rail bodies 5; a third stepper motor 9 is fixedly mounted on one end of the third linear slide rail body 8, and the third stepper motor 9 is located at the left side of the third linear slide rail body 8;

[0028] It is obvious that the output shaft of the stepper motor is fixed to the end of the ball screw inside the corresponding linear slide body, thereby driving the slider to slide along the side wall of the linear slide body, thereby achieving corresponding displacement in various directions (prior art).

[0029] A plurality of drivers 19 are fixedly mounted on the top of the control box 18. The plurality of drivers 19 are electrically connected to the corresponding two first stepper motors 3, two second stepper motors 7 and a single third stepper motor 9 respectively, and can start / stop the corresponding stepper motors to achieve the ability of controlling the axis, and can change the frequency and speed of the axis movement by setting parameters, so that the three-axis linear motion of XYZ and the independent two-axis rotational motion can be performed by artificial control, thereby changing the positional relationship of the two end effectors;

[0030] In actual application, a power supply interface with a power supply voltage of 220VAC and three bridge sockets can be used to connect the five linear guide stepper motors of the device (including two first stepper motors 3, two second stepper motors 7 and a single third stepper motor 9), and the travel of the device's X, Y, and Z axes can be controlled by setting parameters.

[0031] When using the device for testing the distance and angle of the sensor, the relative distance and relative angle between the adjustable end fixtures are controlled by manual operation or the control box 18; the two end fixtures are simultaneously immersed in the glass container 17, and the test effect can be achieved by filling the glass container 17 with liquids of different media; the main end fixture 14 has linear motion of the three axes of X, Y, and Z and rotation of the two axes; the auxiliary end fixture 15 has linear motion of the two axes of Y and Z; in the case of only one power source, the ZX axis can be rotated simultaneously, and the internal water-based paint itself can generate three-axis rotation of the XYZ axis;

[0032] In addition, the material cost of the entire device is less than 3,000 yuan, and it is relatively small in size. It also has two end clamps (furthermore, the end clamps can be replaced with corresponding size clamps according to the different outer diameters of the sensors to be clamped). It can clamp two sensors or a group of opposing sensors at the same time, and can meet the distance, angle, and medium tests at the same time, and can test the three factors in one. At the same time, it is also equipped with a control box, and the operator can choose automatic or manual control during the distance test, which is more in line with the use needs when verifying the quality or performance of the sensor according to the design requirements.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
