Linear cutting sample fixture

Abstract

The invention belongs to the field of reactor engineering, and particularly relates to a linear cutting sample fixture convenient for radioactive environment and samples. The fixture comprises an electromagnetic base and a carrying platform; the electromagnetic base comprises a side wall and a horizontal platform; an electromagnetic coil is arranged in the electromagnetic base; and the carrying platform is arranged on the horizontal platform. The samples on the carrying platform are fixed through paraffin, and therefore the linear cutting radioactive sample fixture which is simple in structureand low in manipulator operation difficulty is obtained. Remote operation of personnel is achieved, strong source irradiation to operators is effectively avoided, and personnel security and long-termbody health are guaranteed.

Description

technical field [0001] The disclosure belongs to the field of reactor engineering, and in particular relates to a wire-cut sample fixture that is convenient for radioactive environments and samples. Background technique [0002] In the reactor field, there are a large number of long-term service equipment in the reactor. The safety and service life of these equipment are important factors related to the safety of nuclear power plants. Therefore, it is very important to systematically study the performance evolution of related equipment and related materials in the irradiation environment. It is important that in the experimental process, transmission electron microscope samples, small punch experimental samples, etc. generally need to cut slices of appropriate thickness from the blank for grinding and polishing.

Problems solved by technology

[0002] In the reactor field, there are a large number of long-term service equipment in the reactor. The safety and service life of these equipment are important factors related to the safety of nuclear power plants. Therefore, it is very important to systematically study the performance evolution of related equipment and related materials in the irradiation environment. It is important that in the experimental process, transmission electron microscope samples, small punch experimental samples, etc. generally need to cut slices of appropriate thickness from the blank for grinding and polishing. When cutting the blank, the sample blank needs to be fixed on the sample holder of the wire cutting machine. In order to carry out accurate cutting and sampling, in the field of reactors, for radioactive samples, it is necessary for personnel to operate remote manipulators outside the lead wall. Ordinary manipulator operations cannot realize the compact wire cutting machine. fine operation tasks, and the current related cutting fixtures require personnel to perform fine operations at close range, and cannot meet the safety requirements in the face of highly radioactive samples. Therefore, it is necessary to design a cutting tool that can be applied to existing manipulators for radioactive samples. Machine sample holding tool to realize remote manipulator operation on radioactive samples
