For convenience of calibration, the calibration test platform in this embodiment is horizontally disposed, a base 5 for supporting the operation surface 1 is disposed below the operation surface 1, and a leveling mechanism is mounted on the base 5. The leveling mechanism can be selected according to the use requirement, in the embodiment, the leveling mechanism selects the leveling jackscrew 6, the leveling jackscrews 6 are uniformly distributed under the operating surface 1, and the upper end of the leveling jackscrew 6 is abutted to the operating surface 1. As shown in fig. 1, there are 4 leveling jacks 6, but of course, there may be 3 or 5.
The operating surface 1 is made of a marble plate, and in order to reduce abrasion and friction of marble in the test process, lubricating alcohol is arranged on the marble plate.
The mounting mechanism 2 comprises a mounting frame 7 and a pressing block 8 arranged in the mounting frame 7, and the pressing block 8 and the side wall of the mounting frame 7 fix the measured object 3. The pressing block 8 and the side wall of the mounting frame 7 are jointly fixed in the measured piece 3, the structure and the size of the pressing block 8 are changed, the measured pieces 3 with different specifications can be installed in the mounting frame 7 to be measured, the application range of the calibration test platform is wider, and the use cost is lower.
In order to facilitate the calibration of the measured object 3, the mounting bracket 7 is a regular hexahedron. Because the accuracy of the mounting frame 7 is required to be high to ensure the test accuracy, and the mounting frame 7 is hard to avoid abrasion in the using process, in order to reduce the abrasion of the mounting frame 7 in the test, a protrusion 9 protruding outwards perpendicular to the surface is arranged at the surface angle of any one surface of the mounting frame 7.
