In one example, referring to fig. 1 and 2, a structure of a device for rapidly measuring the wall thickness of a composite material cover without demolding consists of a height gauge 1, a wall thickness gauge 2, a rotary clamping mechanism and a base 4, wherein the rotary clamping mechanism comprises a rotary sleeve 3, a clamping sleeve 5 and a rotary pin 7, the clamping sleeve 5 is fixed on the height gauge 1 through a first screw 6, and the rotary sleeve 3 is hinged with a bracket of the clamping sleeve 5 through the rotary pin 7 and is fixed through a second screw 8. The wall thickness gauge 2 also has a tip 9 at the end.

The device base 4 can realize the positioning of the base 4 and the flange in the measuring process, and the base is placed at the flange fixing position before and after the wall thickness is measured. The height gauge 1 determines the vertical height of a wall thickness measuring point, and the wall thickness gauge 2 realizes the measurement of the wall thickness by rotating the clamping mechanism 1. Before use, the base 1 is placed at a fixed position of a flange of a mold, values are determined through the height gauge 1, the wall thickness gauge 2 and the rotary clamping mechanism, and original values comprise readings of the height gauge 1 and the wall thickness gauge 2. If the wall thickness needs to be measured in the operation process, the base 4 is placed at a specific position of a die flange, the height gauge 1 is adjusted to be the same as the first reading, the wall thickness gauge is moved through the rotary clamping mechanism to enable the tip of the wall thickness gauge to be perpendicular to a tangent line of a measuring point of the cover body, and the reading of the wall thickness gauge is read. And the difference value between the reading of the wall thickness ruler and the reading of the original wall thickness ruler is the wall thickness of the cover body.

The basic motion relationship which can be realized is as follows:

(1) adjusting movement of the height gauge 1;

(2) the wall thickness ruler 2 and the rotary clamping mechanism act together to realize movement adjustment;

(4) the outer surface of the composite material cover body is matched with the wall thickness gauge 2 through the height gauge 1 and the rotary clamping mechanism to be in contact with the cover body, and an operator can obtain the wall thickness by reading the difference value of the two readings of the wall thickness gauge.

Referring to fig. 3 and 4, the method is applied to the measurement of the wall thickness of the demoulding front cover body after the forming of a certain type of radome is finished, and the specific operation process is to place the base at the flange fixing position before and after the measurement of the wall thickness. The height gauge 1 determines the vertical height of a wall thickness measuring point, the wall thickness gauge 2 realizes the measurement of the wall thickness (point A) at the initial position through rotating the clamping mechanism 1, and data is recorded; in the operation process, the base is placed at a specific position of a die flange, the height gauge 1 is adjusted to be the same as the first reading, the wall thickness gauge is moved by rotating the clamping mechanism to enable the tip of the wall thickness gauge to be perpendicular to a tangent line of a measuring point (point B) of the cover body, and the reading of the wall thickness gauge is read. And the difference value between the reading of the wall thickness ruler and the reading of the original wall thickness ruler is the wall thickness of the cover body.
