A welding device for a calibration model of a whole body counter for internal irradiation

Abstract

The invention relates to a welding device for a calibration model of an internal irradiation whole body counter, comprising a welding cavity (2) for placing the model, a first model fixture arranged in the welding cavity (2) for radially clamping the model, and A second model fixture for axially clamping the model is arranged outside the welding cavity (2), and the second model fixture is connected with a drive system capable of driving the model to rotate; a welding torch (7) passes through the welding cavity (2) and the second model fixture. The top of a model fixture, its torch nozzle (8) is pressed tightly on the weld seam of the model shell. The welding device of the present invention can convert the welding seam that is not originally on a plane to a fixed welding point, thereby realizing automatic uniform-speed welding of the equipment, ensuring the welding quality and improving the welding yield.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a welding device for calibrating a model of an internal irradiation whole-body counter, which is mainly used for welding the plastic shell of a BCAM model. Background technique [0002] The BCAM model used for the calibration of internal irradiation whole body counter equipment is a simplified physical model of the human body, which simplifies the human body into 10 hollow cylinders / elliptical cylinder plastic containers of different sizes and sizes, and fills the radioactive solution inside each container Simulates the uniform distribution of radioactive substances in the human body. According to the molding characteristics of plastic containers and the strict requirements of the BCAM model on the wall thickness of plastic container shells, it is necessary to process the model shells into suitable parts according to different molding processes, such as side walls, b...

AI Technical Summary

Problems solved by technology

It is less difficult to weld straight line welds on the plane, but it is easier to weld curved welds on the plane or welds that are not on the same plane (such as the weld between the end cover and the side wall of the BCAM model). It is very difficult, which directly leads to the fact that the welding skill level of the welding worker will directly affect the quality and yield of welding
