[0043] Working principle or structural principle: When measuring large thin-plate workpieces, first place the workpiece on the workbench 5. Since the workbench 5 is inclined with respect to the ground, under the action of gravity, the workpiece slides downward along the surface of the workbench 5, causing the bottom edge of the workpiece to slide onto the workpiece positioning block 18, thereby positioning the bottom edge of the workpiece. At this time, the workpiece can be laid flat on the workbench 5, thus eliminating the need to use clamping fixtures to clamp thin-plate workpieces, avoiding part deformation caused by clamping, and also saving the clamping process;

[0044] Drive the probe system 8 to move on the surface of the workpiece through the X-axis assembly 2 and the Y-axis assembly 7. The optical probe on the probe system 8 measures the elements to be measured on the surface of the workpiece. Among them, the camera on the probe system 8 displays the captured image on the probe display device 9, so as to observe the measurement details in real time through the probe display device 9. At the same time, the optical probe and the camera on the probe system 8 transmit the captured data to the all-in-one computer 10 in real time. The measurement program and data processing program in the all-in-one computer 10 calculate and process the detected data to obtain the specific data of the thin-plate workpiece;

[0045] When moving in the X-axis direction, the measurement personnel pull the X-axis moving seat 13 to move through the handle 15, so that the X-axis moving seat 13 can slide along the direction of the X-axis guide rail 11, thereby enabling the device to move along the X-axis direction of the workpiece. When the X-axis needs to stop moving, the measurement personnel turn the handle on the positioning shaft 16 by hand, causing the positioning shaft 16 to rotate. Then, one end of the positioning shaft 16 can abut against the X-axis guide rail 11 to lock the movement in the X-axis direction, thus realizing the movement and locking in the X-axis direction;

[0046] When moving in the Y-axis direction, the measurement personnel turn the handle on the rotating shaft 25 by hand. The rotating shaft 25 drives the belt pulley 26 to rotate. The belt pulley 26 drives the movement of the synchronous belt 27. The synchronous belt 27 drives the Y-axis moving seat 22 to slide along the direction of the Y-axis guide rail 21, enabling the probe system 8 to move in the Y-axis direction of the workpiece. The combination of the X-axis and the Y-axis enables the probe system 8 to move to any position on the entire surface of the workpiece. When it is necessary to stop moving in the Y-axis direction, the staff rotates the knob on the rotating rod 31, causing the threaded rod 32 to rotate on the locking clamp block 29, and then driving the second clamp block 34 and the first clamp block 33 to approach each other, so that the through hole 35 is tightly held and locked, thus realizing the locking in the Y-axis direction and enabling the device to move and lock in the Y-axis.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
