Spherical prism holder for measuring the coordinates of the center of a circular hole

Abstract

The invention provides a spherical prism sleeve base for measuring the center coordinates of a round hole. The spherical prism sleeve base for measuring the center coordinates of the round hole aims to solve the problems that according to a traditional adjustment and measurement method, a large amount of time is consumed, and the accuracy is low. The spherical prism sleeve base for measuring the center coordinates of the round hole is of an inward-concave structure with an opening facing upwards, the outer surface of the sleeve base is hemispherical, the inner surface of the sleeve base is in the shape of a cone with a conical tip facing downwards, the central axis of the inner surface of the sleeve base and the central axis of the outer surface of the sleeve base coincide, the distance between the centre of sphere of the hemispherical surface of the sleeve base and the conical surface of the conical inner surface of the sleeve base is the same as the radius of a spherical prism placed in the sleeve base, a groove is formed in the upper end of the sleeve base and penetrates through the inner surface and the outer surface of the sleeve base, and the opening is located in the upper surface of the sleeve base. When the sleeve base is used for measuring the center coordinates of the round hole in a device, operation processes can be simplified, labor investment is reduced, the measurement efficiency and the measurement accuracy are improved, as a result, the construction quality is improved, the construction period is shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a measuring tool in the installation process of a nuclear power plant, in particular to a socket for placing a spherical prism when adjusting and measuring the center coordinates of a round hole of equipment provided with a round hole. Background technique [0002] During the installation of nuclear power equipment, the equipment has its design reference point during installation, so that the cooperation between various equipment can be more reasonable, thereby improving the safety and stability of the equipment during use. Therefore, after the equipment is installed in the factory building, it is necessary to adjust and measure the installation position of the equipment to ensure that the equipment is installed at the design reference point. [0003] Many nuclear power equipment are equipped with round holes such as bolt holes, and the installation reference point of these equipment is often set as the center of these round ho...
