The leveling table 2 is assembled on the front side of the support back frame 3 and is used to place the cold heading sample, providing an operating platform for measurement operations. The measuring mechanism includes a contact-type high-precision measuring ruler correspondingly installed at the top of the support back frame 3, used to measure the height of the cold heading sample. The robotic arm (not shown in the figure) is used to select the corresponding leveling table 2 according to the sample specifications and place the cold heading sample at the center of the leveling table 2. The control unit (not shown in the figure) is used to control the piston rod 7 of the measuring ruler of the measuring mechanism to extend and contact the cold heading sample, calculate the height of the cold heading sample based on the piston displacement, and upload the data to the test management system. The robotic arm can use existing technology to realize its function, and its purpose is to hold the cold heading sample with a robotic arm and place it on the equal height worktable 2; the control unit also realizes data acquisition and upload to the data center (such as the central processing unit) for analysis, storage and display by integrating existing technology functional units.

[0021] like Figures 3-4 As shown, the measuring mechanism includes a mounting plate 11 correspondingly mounted on the top of the support frame 3. A measuring ruler 9 is fixedly mounted at the center of the top of the mounting plate 11.

A pneumatic clamping mechanism 10 is also provided on the mounting plate 11. The pneumatic clamping mechanism 10 is symmetrically arranged on both sides of the measuring ruler piston rod 7, and the clamping surface is in contact with the outer wall of the measuring ruler piston rod 7.
