[0026] The two groups of test components are arranged symmetrically. Both groups of test components can test two groups of sensors 5 to be tested at the same time. Therefore, the device can detect four groups of sensors 5 to be tested at one time. When the electric push rod 20 (model DYTP450- / 110) pushes the sliding column 14 to slide, the sliding column 14 drives the moving grid 17 to slide on the fixed grid 3. The moving grid 17 and the fixed grid 3 slide in cooperation to generate stroke data (such as the vernier caliper principle), so as to accurately know the moving stroke of the driving plate 13 driven by the sliding column 14.
[0027] By connecting two groups of sensors 5 to be tested with the ends of two groups of driving plates 13, the electric push rod 20 pushes the sliding column 14 to slide, and the sliding column 14 drives the moving grid 17 to slide on the fixed grid 3 to generate travel data. At the same time, the sliding column 14 pulls the output ends of the two groups of sensors 5 to be tested to move through the driving plate 13, and compares the display data of the sensor 5 to be tested with the travel data to determine whether the performance data of the sensor 5 to be tested is accurate.

[0034] The lower ends of the installation frames 8 on both sides of the fixed fence 3 are fixedly connected with fixing columns 10 , and the upper end of the base 1 is provided with two groups of slide grooves 21 , and the lower ends of the two groups of fixing columns 10 are slidably connected in the two groups of slide grooves 21 .
[0035] like Figure 1-Figure 4 As shown, the fixing column 10 and the slide groove 21 define the sliding path of the installation frame 8, so that the output end of the sensor 5 to be tested moves linearly, thereby increasing the test accuracy.
[0036] A mounting seat 4 is fixedly connected to the upper end of the base 1 , a mounting plate 6 is fixedly connected to the tail of the sensor 5 to be tested, and the mounting plate 6 is clamped in the mounting seat 4 .
[0037] like Figure 1-Figure 4 As shown, the mounting base 4 facilitates the installation of the sensor 5 to be tested, so that the position of the sensor 5 to be tested is fixed.
[0038] The working principle of a linear displacement sensor testing device provided by the utility model is as follows:
[0039] By connecting two groups of sensors 5 to be tested with the ends of two groups of driving plates 13, the electric push rod 20 pushes the sliding column 14 to slide, and the sliding column 14 drives the moving grid 17 to slide on the fixed grid 3 to generate travel data. At the same time, the sliding column 14 pulls the output ends of the two groups of sensors 5 to be tested to move through the driving plate 13, and compares the display data of the sensor 5 to be tested with the travel data to determine whether the performance data of the sensor 5 to be tested is accurate.
