Abstract

The invention belongs to the technical field of fuel component manufacturing and particularly relates to a fuel assembly guide pipe plug pressing device. The fuel assembly guide pipe plug pressing device comprises a control system, an end plug feeding device, an end plug positioning and pressing-in device, a fuel rod clamping device, feeding and discharging wheels, a fuel rod clamping inlet and outlet device, a feeding and discharging device and a supporting frame. Technical problems of high skill requirements on operators, difficulty in guarantee of plug pressing quality stability and high waste of human resources due to manual operation in a whole process of an existing guide pipe plug pressing mode are solved. By the fuel assembly guide pipe plug pressing device, automatic end plug supply and automatic feeding and discharging of guide pipes can be realized; by an automatic end plug positioning mechanism, end plugs are taken and correctly placed at to-be-pressed positions by a pneumatic chuck to realize automatic end plug positioning, plug pressing force and plug pressing holding time can be adjusted to guarantee stability and reliability of plug pressing quality, and manpower and material resources are greatly saved.

Description

technical field [0001] The invention belongs to the technical field of fuel assembly manufacturing, and in particular relates to a plugging device for a fuel assembly guide pipe. Background technique [0002] The guide tube is an important component of the fuel assembly skeleton, and the correct pressing of the end plug into the guide tube is related to the quality of the guide tube's shape and size, and has a direct impact on the welding quality of the subsequent guide tube and end plug. Guide tube products are as follows: figure 1 shown. [0003] The existing traditional guide tube plugging mode is: manually lift a guide tube to the supporting wheel of the plugging device, put one end plug into the positioning hole of the end plug, manually feed the guide tube cladding tube into contact with the end plug and adjust Alignment, start the clamping cylinder, clamp the cladding tube, then start the end plug feeding cylinder, press the end plug into the cladding tube, and obse...
