Abstract

The invention discloses a machine special for automatically grinding a civilian nuclear main bolt hole. The machine comprises a pneumatic motor, a support, a bearing structure beam, a positioning block, a large belt wheel, a guide column, a grinding tool body, a coupler, a small belt wheel and a synchronous belt, wherein the output end of the pneumatic motor is connected with the coupler, the coupler is fixedly connected with the small belt wheel, and the small belt wheel is connected with the large belt wheel through the synchronous belt. The guide column is eccentrically connected with the large belt wheel, the guide column is perpendicular to the plane where the large belt wheel is located, the grinding tool body for grinding the main bolt hole formed in a nuclear power pressure container cylinder is arranged at the end away from the large belt wheel, of the guide column, and the rotation center of the grinding tool body is coaxial with the main bolt hole. The machine has the advantages of being simple in structure, light in device weight, convenient to operate, convenient and quick to maintain and store and the like, achieves mechanical operation, is also suitable for batch production, the thread surface roughness of the main bolt hole of the nuclear power pressure container cylinder is effectively reduced, and the size accuracy of threads is improved.

Description

technical field [0001] The invention relates to a special machine for automatic grinding of main bolt holes of civil nuclear power plants, which belongs to the field of nuclear power equipment and is used for automatic grinding of main bolt holes of third-generation reactor pressure vessels. Background technique [0002] In recent years, with the rapid development of the nuclear power industry and the strict requirements for the safety of nuclear power products worldwide, higher standards have been put forward for the product quality of nuclear power equipment. [0003] The reactor pressure vessel is an important equipment for the boundary barrier of coolant pressure in the primary circuit of nuclear power, and has the characteristics of high temperature, high pressure and high radioactivity. In order to ensure no leakage of radioactive substances under its operation and test conditions, the sealing of the top cover and the pressure vessel cylinder is an important link in th...
