[0043] Working principle or structural principle: When measuring a large thin plate workpiece, first place the workpiece on the workbench 5. Since the workbench 5 is inclined with the ground, the workpiece slides downward along the surface of the workbench 5 under the action of gravity, so that the bottom edge of the workpiece slides onto the workpiece positioning block 18, and then the bottom edge of the workpiece is positioned. At this time, the workpiece can be laid flat on the workbench 5, and there is no need to use a clamping fixture to clamp the thin plate workpiece, thereby avoiding deformation of parts caused by clamping, and also eliminating the clamping process;

[0044] The probe system 8 is driven to move on the workpiece surface by the X-axis assembly 2 and the Y-axis assembly 7, and the optical probe on the probe system 8 measures the measuring elements on the workpiece surface, wherein the camera on the probe system 8 displays the captured image on the probe display device 9, and then the measurement details are observed in real time through the probe display device 9, and at the same time, the optical probe and camera on the probe system 8 transmit the captured data to the integrated computer 10 in real time, and the measurement program and data processing program in the integrated computer 10 calculate and process the detected data to obtain specific data of the thin plate workpiece;

[0045] When moving in the X-axis direction, the measurement personnel pulls the X-axis moving seat 13 by the handle 15 to move, so that the X-axis moving seat 13 can slide along the direction of the X-axis guide rail 11, and then the device can move along the X-axis direction of the workpiece. When the X-axis needs to stop moving, the measurement personnel manually rotates the handle on the positioning shaft 16 to rotate the positioning shaft 16, and then one end of the positioning shaft 16 can be against the X-axis guide rail 11 to lock the movement in the X-axis direction, thereby realizing the movement and locking in the X-axis direction;

[0046] When moving in the Y-axis direction, the measurement personnel manually rotate the handle on the rotating shaft 25, and the rotating shaft 25 drives the pulley 26 to rotate, and the pulley 26 drives the movement of the synchronous belt 27, and the synchronous belt 27 drives the Y-axis moving seat 22 to slide along the direction of the Y-axis guide rail 21, so that the probe system 8 can move in the Y-axis direction of the workpiece, and then the combination of the X-axis and the Y-axis enables the probe system 8 to move to any position along the entire surface of the workpiece. When it is necessary to stop moving in the Y-axis direction, the staff turns the knob on the rotating rod 31 to make the threaded rod 32 rotate on the locking clamp 29, thereby driving the clamp block 2 34 and the clamp block 1 33 to approach each other, so that the through hole 35 is tightly locked, and then the locking in the Y-axis direction is realized, so that the device can move and lock on the Y-axis.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
