Welding device for internal radiation whole body counter calibration model

Abstract

The invention relates to a welding device for an internal radiation whole body counter calibration model. The welding device comprises a welding cavity (2) used for containing the model, a first modelfixture arranged inside the welding cavity (2) and used for radially clamping the model and a second model fixture arranged outside the welding cavity (2) and used for axially clamping the model. A driving system capable of driving the model to rotate is connected to the second model fixture. A weld gun (7) penetrates through the welding cavity (2) and the top of the first model fixture. A weld gun spray nozzle (8) of the weld gun (7) abuts against the weld seam of a model shell. The welding device can convert weld seams not located in the same plane originally to a fixed welding point. Accordingly, automatic constant-speed welding of equipment is achieved, the welding quality is guaranteed, and the welding finished product rate is increased.

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
