Abstract

The invention aims to provide a balance weight assembly fixture for machining guide vanes with multiple specifications. The balance weight assembly fixture for machining guide vanes with the multiplespecifications is composed of balance weight brackets, a balance weight pressing block, a balance weight locking part and the like. The assembly angle and position of the fixture are adjusted with a hinge shaft and a chain to suit the guide vanes with different specifications. Counter weights with different specifications are fixed by the pressing block to realize rotating balance of the guide vanes. Fastening and connecting of assemblies of the fixture are realized by the connecting parts (high strength bolts, screws) and pin shafts. According to the balance weight assembly fixture for machining the guide vanes with the multiple specifications, corresponding parts of the guide vanes of the component parts of a water guide mechanism is machined on a horizontal lathe by using the balance weight assembly fixture in the machining process of a journal and a shaft shoulder, and the machining size meets the drawing requirements. The purpose of using the assembly fixture in the technical field of water turbines is realized. The balance weight assembly fixture for machining the guide vanes with the multiple specifications has the advantages of convenient assembly, simple use, convenient adjustment, wide application range, shortened guide vane machining time limit and the like, and can be widely applied to the machining process of the guide vanes with the multiple specifications in hydraulic turbine units.

Description

technical field [0001] The invention relates to the technical field of water turbines, in particular to an assembly jig for balancing counterweights used for mechanical processing of guide vanes in a water guide mechanism of a vertical unit. Background technique [0002] At present, a water turbine is a power device that converts water flow energy into rotating mechanical energy, which drives a generator to rotate to generate electrical energy. The combination of water turbine and generator is called hydro-generator set. [0003] Hydrogenerator sets are the core equipment of hydropower stations. In order to monitor, control and ensure the normal operation of the hydroelectric generator set, to achieve safety, reliability, cost-effectiveness and high efficiency, a complete set of auxiliary equipment systems, such as fast gates, turbine oil systems, compressed air systems, water supply and drainage systems and automation equipment, has been installed in the hydropower station...
