The plurality of flattening mechanisms 2 are arranged at intervals in a ring on the frame 1. The plurality of flattening mechanisms 2 are used to clamp the outer edge of the workpiece to be measured 20, and can respectively drive the clamped part away from the reference position on the workpiece to be measured 20 to flatten the workpiece to be measured 20.

[0085] The flattening device 10 provided by the embodiment of the present utility model realizes the flattening of the workpiece to be measured 20 by arranging a plurality of flattening mechanisms 2 on the frame 1 and clamping the outer edge of the workpiece to be measured 20 by each flattening mechanism 2 to drive the clamped part away from the reference position on the workpiece to be measured 20, thereby improving the accuracy of subsequent tests.

[0086] Among them, the plurality includes two or more. In one embodiment, as Figure 1 shown, the reference position is located at the edge of the workpiece to be measured 20.

[0087] The flattening device 10 further includes a fixing mechanism 3 arranged on the frame 1. The fixing mechanism 3 is used to clamp and fix the reference position. By clamping and fixing the reference position on the workpiece to be measured 20, the invariance of the reference position is ensured, and then the flattening of the workpiece to be measured 20 can be realized through the cooperation of the fixing mechanism 3 and each flattening mechanism 2.

[0088] In other embodiments not shown in the figure, the reference position may also be located in the central area of the workpiece to be measured.

[0089] In one embodiment, as Figure 1 and Figure 2 shown, the workpiece to be measured 20 is a rectangular workpiece, and the first vertex 20a of the workpiece to be measured 20 is used as the reference position. At this time, the fixing mechanism 3 is used to clamp and fix the first vertex 20a of the workpiece to be measured 20.
