Embodiment 1

[0014] Embodiment 1 A weaving welding method for the positioning rib support block of the V-shaped rib frame base of the hydro-generator stator. Take the stator comb plate 2 as the reference, use the reference circle on the comb plate 2 to find the radius and chord distance of the measuring rib 7, and use the measuring rib 7 as the reference to swing and weld the positioning rib support block 1; use the fixing frame 6 to spot weld the V-shaped rib Above, use the bolts on the fixing frame 6 and the bolts on the measuring ribs to adjust the measuring ribs in four directions to realize the weaving welding connection of the positioning rib supporting blocks.

[0015] The measuring ribs are processed on six sides, the length is the same as that of the positioning ribs, the dimensional accuracy of the straightness and parallelism is guaranteed, and the lower connecting bars and connecting bars are perpendicular to each other after welding. The lower connecting plate is machined with...

Abstract

The invention relates to a method for weaving welding of a positioning rib supporting block of a hydraulic generator stator V-shaped rib base, which belongs to the technical field of generators. The method for the weaving welding of the positioning rib supporting block of the hydraulic generator stator V-shaped rib base welds the positioning rib supporting block on a hydraulic generator stator base through weaving welding, and is characterized by comprising the following steps of: on a basis of a stator pectinate plate, using a basic circle on the pectinate plate to find out the semidiameter and the chord distance of a measured rib, and performing the weaving welding on the positioning rib supporting block based on the measured rib; and adopting a fixed mount welded on a V-shaped rib through spot welding, and using bolts on the fixed mount and the bolts on the measured rib to adjust the measured rib in four directions so as to realize the weaving welding connection of the positioning rib supporting block. The method has the advantages of simple method, safe use, low processing cost, high processing efficiency, high processing accuracy, good product quality and the like, and improves the designing and manufacturing levels of products.

Description

technical field [0001] The invention belongs to the technical field of generators, in particular to a weaving welding method for positioning rib support blocks of a V-shaped rib base of a hydroelectric generator stator. Background technique [0002] At present, the design of the stator frame of the Francis turbine generator has changed from the traditional ring-plate structure to the V-shaped rib structure. Coil temperature, processing and manufacturing are more scientific and advanced. But this structure will present great difficulty to the positioning rib support block of weaving welding, the traditional positioning rib support block welding process has been completely unsuitable for the welding of the positioning rib support block of the V-shaped rib structure stator frame. Contents of the invention [0003] In order to solve the technical problems existing in the known technology, the present invention provides a weaving welding method for positioning rib support bloc...
