After the side of the workpiece 16 to be detected is placed against the second shape and position size fixing block 24, a certain gap is left between the first shape and position size fixing block 6 and the workpiece 16 to be detected, which can be detected by the go-no-go gauge 22.
[0025] As shown in Figures 1-2 , the top surface of the workbench 5 is fixed with six L-shaped placement racks 7, which are right-angle L-shaped. The L-shaped placement racks 7 are divided into two groups, each group having three L-shaped placement racks 7. Each group of L-shaped placement racks 7 is arranged equidistantly behind the fixed bottom plate 9. Two dial gauges 8 are inserted into the L-shaped placement racks 7 for detecting the flatness of the rear side of the workpiece 16 to be detected.
[0026] As shown in Figures 1-2 , the top surface of the workbench 5 is fixed with four L-shaped leaning plates 15 through bolts. Each group of L-shaped leaning plates 15 is fixed in front of the fixed bottom plate 9.

[0030] Specific working principle:
[0031] In use, the workpiece 16 to be detected is placed on the fixed base plate 9, the positioning pin 19 is inserted into the positioning hole on the workpiece 16 to be detected, and the small cylinder below the positioning pin 19 is inserted into the positioning hole on the top surface of the fixed base plate 9, so as to position the workpiece 16 to be detected. After positioning, the workpiece 16 to be detected is quickly clamped by the quick clamps 18, then the positioning pin 19 is removed, and the positioning pin 19 is inserted into the top surface of the pin seat 20. After rotating the rotating connecting plate 11 to be horizontal, the rotating connecting plate 11 is fixed by the fixed bolt 17, and then the dial gauge 8 is inserted into the through hole on the placement plate 12. The flatness of the top surface of the workpiece 16 to be detected is detected. After detection, the fixed bolt 17 is removed from the rotating connecting plate 11, the handle 23 is pulled to make the rotating connecting plate 11 flip up, and the subsequent detection process is not delayed. The flatness of the rear of the workpiece 16 to be detected is detected by the dial gauge 8 on the L-shaped placement frame 7, and the flatness of the front of the workpiece 16 to be detected is detected by the dial gauge 8 on the L-shaped back plate 15. At the same time, the threaded rotating pin 14 is rotated, and when the threaded rotating pin 14 can pass through the through hole in front of the workpiece 16 to be detected, it is qualified, otherwise it is unqualified. The through-stop gauge 22 on the clamping piece 21 is moved in turn to detect the through hole on the workpiece 16 to be detected. The through hole is connected, the end is stopped, and it is qualified, otherwise it is unqualified.
[0032] Through the above operation, the detection efficiency is significantly improved by the gauge. Before, it takes 30 minutes to check one product, now it takes 3 minutes. The measurement accuracy of the hole diameter is more accurate, and the misoperation of the measuring tool is prevented. The gauge has no special requirement for the working environment, and can work at room temperature without constant temperature working environment.
