detailed description

The present invention will be described in detail below in conjunction with examples.

The inner cavity depth measuring ruler of the complex concave curved surface of the present invention is mainly composed of a fixed length, a backing plate, a vernier ruler, a reference block, a screw, a probe and a probe. The fixed ruler is the main body of the inner cavity depth measuring ruler of complex concave curved surface, and the fixed ruler is formed with a metric main scale, and the main scale unit is millimeter. One end of the fixed ruler is formed with a backing plate perpendicular to it. The function of the backing plate is to position the main scale as a reference and to limit the vernier ruler. Its inner side can also be used as a reference plane for width or length measurement; The other end of the ruler is connected with a reference block by two screws to ensure that the two are perpendicular to each other. The reference block is in the form of a cuboid, and its lower plane is the measurement reference plane of the inner cavity depth measuring ruler with complex concave curved surface.

The vernier ruler is installed on the fixed ruler and uses it as a slide rail, and the vernier ruler can slide on the fixed ruler, and the two form a closely matched moving pair. The vernier scale and the main scale correspond to the position to set the sub scale, and the sub scale corresponds to the main scale to read the decimal place of the measured value. The upper side of the vernier ruler can be in parallel close contact with the inner side of the backing plate or a certain distance away, and the cooperation of these two sides can make the present invention have the function of measuring width or length. The vernier and the probe are connected together by two screws, and the probe moves synchronously with the vernier. The probe is specially used to measure the depth of the inner cavity of the complex concave surface, and its lower end is a probe, which is hemispherical in shape, so that the probe is in point contact with the measured concave surface. When the cavity depth measuring ruler on the complex concave curved surface is at the zero position (that is, the backing plate and the vernier scale are close together), the lower surface of the probe is flush with the lower surface of the reference block.
