Problems solved by technology
During the plugging process, excessive gaps will easily lead to incomplete penetration, uneven gaps will easily lead to uneven welding, and plugging deflection will lead to subsequent inability to weld, or even failure to repair and must be scrapped. The plugging process directly determines the subsequent welding quality
The traditional plugging mechanism can only realize the pressing of one type of end plug

Embodiment Construction
[0011] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0012] Such as figure 1 As shown, the fuel rod automatic end plugging device of the present invention includes a plugging cylinder 1, a connecting rod 2, an end plug pneumatic chuck 3, a cladding tube pneumatic chuck 5, a rubber fixing mechanism A7, and a rubber fixing mechanism B8; Plug cylinder 1 is connected with end plug pneumatic chuck 3 through connecting rod 2 . For cladding tubes of three different specifications, the outer diameters are 15.4mm, 15.7mm, and 22.1mm, and the corresponding end plug diameters are 13.4mm, 14.6mm, and 20.1mm, respectively, and automatic plugging is performed. Loosen the end plug pneumatic chuck 3, place the cladding tube 6 on the rubber fixing mechanism A7 and rubber fixing mechanism B8; the tube delivery mechanism transports the cladding tube 6 in place and stops, and the cladding tube pneumatic chuck 5 c...

Belonging to the technical field of nuclear fuel element preparation, the invention in particular relates to an automatic fuel rod end plug pressing device. The device consists of a plug air cylinder,a connecting rod, an end plug pneumatic chuck, a cladding pipe pneumatic chuck, a rubber fixation mechanism A and a rubber fixation mechanism B. The plug air cylinder is connected to the end plug pneumatic chuck through the connecting rod. The end plug pneumatic chuck is loosened, and a cladding pipe is placed on the rubber fixation mechanism A and the rubber fixation mechanism B. A pipe conveying mechanism conveys the cladding pipe to an appropriate place and stops, and the cladding pipe pneumatic chuck clamps the cladding pipe. An end plug is put into the end plug pneumatic chuck, and is clamped by the end plug pneumatic chuck. The plug air cylinder stretches out and presses the end plug into the cladding pipe. The end plug pneumatic chuck releases the end plug. The cladding pipe pneumatic chuck releases the cladding pipe. The pipe conveying mechanism reverses, and the end plug pressed cladding pipe can be taken out. The automatic fuel rod end plug pressing device provided by the invention has the characteristics of simple structure, low cost, convenient and quick use, and multiple purposes, and by replacing an end plug positioning mechanism and chuck and adjusting the plug pressure, press fitting of fuel rods of three specifications can be achieved.
Description
technical field [0001] The invention belongs to the technical field of nuclear fuel element preparation, and in particular relates to a device for automatically pressing end plugs of fuel rods. Background technique [0002] The fuel rod pressing end plug is to press the end plug into the cladding tube by a plug press machine, so as to prepare for the completion of subsequent fuel rod welding. During the plugging process, excessive gaps may cause incomplete penetration, uneven gaps may cause uneven welding, and deflection of the plugging will lead to failure of subsequent welding, or even failure to repair and must be scrapped. The plugging process directly determines the quality of subsequent welding. The traditional plugging mechanism can only realize the pressing of one type of end plug. Contents of the invention [0003] The purpose of the present invention is to provide a multi-purpose fuel rod automatic end plugging device. The plugging cylinder is used to push the p...
