Abstract
The invention belongs to the technical field of nuclear fuel assemblies and particularly relates to a clamp for welding of a TVS-2M grillwork lattice cell and a coaming. The clamp provided by the invention comprises a base, a limiting block, a lead screw, a handle, a chuck, racks, connecting blocks, Bakelite bodies, metal groove blocks and a movable bottom plate. The problem that the dimensional deviation is large due to the fact that the six edges of a grillwork are all in a free state and are liable to be influenced by welding internal stress when the grillwork lattice cell is welded at present is solved. By using the clamp for welding of the TVS-2M grillwork lattice cell, the relative positions of the grillwork coaming and the lattice cell are fixed, and the shape of the grillwork can be effectively controlled. In addition, the degree of the regular hexagon of the six edges of the clamp is easy to adjust.
Description
Technical field
The invention belongs to nuclear fuel assembly technical field, be specifically related to a kind of TVS-2M screen work lattice cell welding jigs and fixtures.
Background technology
Screen work lattice cell and coaming plate are to manufacture the ingredient that fuel assembly is indispensable, fuel assembly for TVS-2M model, its screen work lattice cell is when welding at present, and six limits of screen work are in free state simultaneously, are affected by welding interior stress, after screen work has welded, three opposite side dimensional discrepancys of screen work are relatively big, and off technical requirement sometimes need to be adjusted when screen work self-inspection, this will make production efficiency reduce, and the difficult quality guarantee of product.
Summary of the invention
The technical issues that need to address of the present invention are: screen work lattice cell six limits of screen work when welding are in free state at present, and the impact being subject to welding interior stress causes dimensional discrepancy bigger.
Technical scheme is as described below:
A kind of TVS-2M screen work lattice cell welding jigs and fixtures, including discoid pedestal, it is installed with a limited block at the disc face edge of described pedestal, leading screw is connected to chuck through described limited block, being positioned at the one end outside described pedestal at described leading screw and be provided with handle, turning handle can drive leading screw to rotate in limited block；At the other end of described leading screw, fixing with the adjustment screw of described chuck and be connected, described adjustment screw rotates with screw synchronous, so that three tooth bars on chuck linearly draw in the center of chuck or deviate from center and separate；During three tooth bars are generally aligned in the same plane, adjacent two tooth bar angulations 120 °；Each described tooth bar is also fixedly connected with contiguous block, each contiguous block be arranged above fix the bakelite body being connected with contiguous block, the cross section of three bakelite bodies is stitched together, and to constitute internal be the outside shape for circle of regular hexagon of hollow out；All studding with metal geosynclinal block on two regular hexagon adjacent edges of described bakelite body, six metal geosynclinal blocks can constitute regular hexagon in space；Being provided with lattice cell quantity to be welded in groove, number of recesses and screen work each edge to be welded on described metal geosynclinal block to match, when described groove is for welding, welding electrode stretches into.
Preferably, being additionally included in movable floor, described movable floor edge stretches between bakelite body and contiguous block；Described movable floor is regular hexagon shape, and the outline of outline size and coaming plate is in the same size, and the edge of movable floor raises up formation step, it is possible to the relative position of fixing screen work lattice cell and coaming plate.
The invention have the benefit that
The TVS-2M screen work lattice cell welding jigs and fixtures of the application of the invention, makes the relative position of screen work coaming plate and lattice cell fix, it is possible to effectively to control the profile of screen work, additionally, fixture six limit regular hexagon degree is also easy to adjust.
Accompanying drawing explanation
Fig. 1 is the welding jigs and fixtures structural representation of the present invention；
Wherein, 1-pedestal, 2-limited block, 3-leading screw, 4-handle, 5-chuck, 6-tooth bar, 7-contiguous block, 8-bakelite body, 9-metal geosynclinal block, 10 movable floors.
Detailed description of the invention
Below in conjunction with drawings and Examples, a kind of TVS-2M screen work lattice cell welding jigs and fixtures of the present invention is described in detail.
TVS-2M screen work lattice cell welding jigs and fixtures as shown in Figure 1, it has discoid pedestal 1, it is installed with a limited block 2 at the disc face edge of described pedestal 1, leading screw 3 is connected to chuck 5 through described limited block 2, make the described leading screw 3 can not large-amplitude sloshing, being positioned at the one end outside described pedestal 1 at described leading screw 3 and be provided with handle 4, turning handle 4 can drive leading screw 3 to rotate in limited block 2.At the other end of described leading screw 3, fixing with the adjustment screw of described chuck 5 and be connected, described adjustment screw is with leading screw 3 synchronous axial system, so that the center of the linearly inside chuck 5 of three tooth bars 6 on chuck 5 is drawn in or deviates from center and separate.During three tooth bars 6 are generally aligned in the same plane, adjacent two tooth bar 6 angulations 120 °.Each described tooth bar 6 is also fixedly connected with contiguous block 7, it is arranged above the bakelite body 8 that be connected fixing with contiguous block 7 at each contiguous block 7, the cross sectional shape of described bakelite body 8 is the profiled shape that the arc section by 1/3 full circle, orthohexagonal adjacent both sides and two straight flanges are constituted, and the cross section of all of three transfer panels 8 is stitched together constitutes the outside shape for circle of regular hexagon that inside is hollow out.All studding with metal geosynclinal block 9 on two regular hexagon adjacent edges of described bakelite body 8, six metal geosynclinal blocks 9 can constitute regular hexagon in space.Movable floor 10 edge stretches between bakelite body 8 and contiguous block 7.Being provided with lattice cell quantity to be welded in groove, number of recesses and screen work each edge to be welded on described metal geosynclinal block 9 to match, when described groove is for welding, welding electrode stretches into.Described movable floor 10 is regular hexagon shape, and the outline size of described movable floor is in the same size with the outline of coaming plate.The edge of movable floor 10 raises up formation step, it is possible to the relative position of fixing screen work lattice cell and coaming plate.
