Embodiment Construction

[0036] The scheme of the present invention will be further described below in conjunction with the accompanying drawings.

[0037] Such as figure 1 As shown, the mixed-flow runner includes runner crown 41, runner blade 42 and runner lower ring 43, and the special combined machine tool processing technology for the mixed-flow runner of the present invention needs to include the matching part of the runner tap 1, The four parts of joint surface 2, upper stop ring 3 and lower stop ring 4 of the runner are machined on the upper crown shaft of the runner. Machining these four parts has its own requirements in terms of processing benchmarks, processing diameters, and processing requirements. Three independent special machines are used in the processing technology of the mixed-flow runner special combined machine tool of the present invention to process these four parts. Partially machining, including the No. 1 special machine for machining the joint 1 of the water discharge cone of...

Abstract

The invention provides a process for machining a combined machine tool special for a mixed flow turning wheel. According to the process, the turning wheel is fixed on a machining platform, the matching position of a runner cone of the turning wheel is machined by using a No.1 special machine, an occlusal surface of a main shaft of a runner crown of the turning wheel is machined by using a No.2 special machine, and an upper leakproof ring and a lower leakproof ring of the turning wheel are machined by using a No.3 special machine. The process for machining the combined machine tool special for the mixed flow turning wheel is designed for the machining of the turning wheel in a construction site plant, and is high in pertinence, convenient to operate and high in manufacturability.

Description

technical field [0001] The invention relates to a machining process for manufacturing a large mixed-flow runner in a factory building. Background technique [0002] In recent years, with the accelerated construction of large-scale hydropower stations, single-unit large-capacity hydroelectric generating units have been successively developed and put into operation. Due to transportation conditions and other considerations, more and more large-scale Francis runners have been or will be manufactured in workshops, which has also become a trend in the manufacture of large-scale hydropower equipment. Due to the investment in hardware equipment and other reasons, the cost of manufacturing in the workshop will inevitably increase, which also poses new challenges for the machining of the rotor in the workshop, and it is possible to manufacture high-quality rotors with relatively low manufacturing costs. The wheel becomes a goal to be achieved. [0003] The diameter of large mixed-f...
