Abstract
The invention relates to welding technical equipment for a square tube, a square tube and a cladding plate and square tube and a small base plate of a nuclear fuel storage framework bush. The welding technical equipment comprises a base plate, lateral fastening frames, a plurality of pneumatic piano type upper pressing plate devices, a first rotary motor, an inner support device with a pneumatic wedge and a support device of the small base plate. The two lateral fastening frames which can be driven to slide by a first air cylinder are mounted on the base plate. The pneumatic piano type upper pressing plate devices are respectively mounted on the two lateral fastening frames. The first rotary motor is mounted at one end of the base plate. The support device of the small base plate is mounted at the other end of the base plate. The inner support device with the pneumatic wedge is mounted on the upper portion of the base plate and comprises a pneumatic wedge component, an inner support plate body, a pull rod and a fourth air cylinder. The support device of the small base plate comprises a second rotary motor, a motor mounting seat, a transmission screw, a screw sleeve, an ejector pin, a third air cylinder and a pneumatic clamping block.
Description
technical field [0001] The nuclear fuel storage grid storage sleeve welding process equipment of the present invention relates to a kind of laser welding process equipment of square tubes, square tubes and cladding plates, square tubes and small bottom plates of nuclear fuel storage grid storage sleeves. Background technique [0002] At present, the spent nuclear fuel storage grids of the boron-aluminum storage casing structure in China still rely on imports. Domestic manufacturers of similar square tubes mostly use die extrusion (large-volume standard parts) or hydraulic expansion (non-standard, but there is a certain amount) method, but the subsequent welding deformation problem is relatively large, and it is difficult to meet the design and use requirements . Contents of the invention [0003] The object of the present invention is to provide a nuclear fuel storage grid storage sleeve welding process equipment for the above shortcomings, which adopts pneumatic wedge ty...
