[0007] Horizontal through hole upper wall of the side push rod seat is provided with pin hole, and the matching positioning hole is arranged in the middle part of side push rod, the pin is inserted into pin hole and positioning hole for positioning of side push rod, so that gap A is formed between side contour block and the surface of workpiece.

[0008] The edge of the through hole of the hole gauge is provided with a step on the base, so that the workpiece is placed on the step and forms a gap B with the base.

[0009] The use method is as follows:

[0010] (1), the workpiece is placed on the base, the size of the base matches the size and shape of the workpiece, the connecting hole of the connecting lug on both sides of the workpiece is aligned with the through hole position, a hole gauge is inserted, on the one hand, the machining accuracy of the connecting hole is detected, and on the other hand, the workpiece is positioned and fixed by the hole gauge;

[0011] (2), the clamping head of the quick clamp is pressed down to tightly press the workpiece, so that a gap A is formed between the bottom surface of the workpiece and the upper end surface of the base;

[0012] (3), the side contour block is pushed horizontally to the side of the workpiece, and after being in place, the side contour block is positioned by penetrating the bolt, and a gap B is formed between the side contour block and the side of the workpiece;

[0013] (4), the quality inspector scans the gap A and the gap B with the two ends of the go-no-go gauge respectively, if the large head of the go-no-go gauge cannot be inserted into the gap, and the small head of the go-no-go gauge can be inserted into the gap, it is proved that the surface contour and position (torsion degree and bending degree) of the workpiece meet the machining requirements; otherwise, the surface contour and position of the workpiece are unqualified.

[0014] Advantages of the utility model

[0015] (1) the utility model is specially used for detecting the outer contour and machining hole position of the aluminum workpiece of the rear support of the auxiliary frame, the outer contour and machining hole position of the workpiece can be detected at one time, and the detection efficiency is high.

[0016] (2) the utility model has compact structure, small occupied area, convenient operation and convenient maintenance.

[0017] (3) the structure form and principle of the utility model can be further expanded, and are suitable for detecting other workpieces. DRAWINGS
