[0059] Tooling principle:

[0060] Fix the hardness tester on the mounting base 6, place the workpiece to be detected on the mobile platform 7, and fix it through the fixture 92. Then, according to the detection requirements, control the operation of the first motor 36, the second motor 54, and the third motor 82, so that the hardness tester and the workpiece move to the specified position for detection at the specified point.

Subsequently, use the first moving mechanism to move the hardness tester in the Y-axis direction to achieve the detection of different transverse positions of the workpiece. At the same time, the second moving mechanism drives the workpiece to move in the X-axis direction, enabling the hardness tester to cover the entire detection area of the workpiece.
