Abstract

The invention belongs to the technical field of fuel assembly manufacturing and particularly relates to a welding electrode clamping device for a TVS-2M grillwork lattice cell and a coaming. The welding electrode clamping device comprises an air cylinder, an upper sealing cover, a lower sealing cover, a pressure measuring opening, a connector, an air inlet, a piston, a nut, a movable screw rod, a buffer device body, an electrode stem, a telescopic rod, an oil filling inlet, an air intake, an adjusting valve, a first movable rod, a second movable shaft, a third movable rod, a fourth movable rod, a first movable shaft, a second movable rod, a third movable shaft, a fourth movable shaft, a fifth movable shaft, a sixth movable shaft, a first connecting sheet, a second connecting sheet, fixing blocks and an insulation sheet. According to the welding electrode clamping device for the TVS-2M grillwork lattice cell and the coaming, the problem that the clamping force of existing welding electrode clamping devices for TVS-2M grillwork lattice cells and coamings is unstable is solved, the clamping pressure of the welding electrode clamping device provided by the invention is stable, the clamping force can be adjusted as required, the welding quality is ensured, and improving of the production efficiency is facilitated.

Description

technical field [0001] The invention belongs to the technical field of fuel assembly manufacturing, and in particular relates to a TVS-2M grid cell and coaming plate welding electrode clamping device. Background technique [0002] The TVS-2M fuel assembly is a modified fuel assembly for the VVER-1000 reactor system, which has high application performance and operational characteristics. [0003] At present, in the manufacturing process of TVS-2M fuel assembly, the welding device used for welding the positioning grid cell and the coaming plate is modified from the original fuel assembly welding device. During welding, the clamping force of the electrode chuck is unstable, which makes it difficult to guarantee the quality of welding, and causes a large number of products to be repaired, which seriously restricts the improvement of production efficiency. Contents of the invention [0004] The technical problem to be solved in the present invention is: the clamping force of t...
