Processing method for machining main studs of large and medium-sized rotor spiders by utilizing rotating tire

Abstract

The invention relates to a processing method for machining main studs of large and medium-sized rotor spiders by utilizing a rotating tire. According to the processing method for machining main studs provided by the invention, a self-aligning thrust roller bearing is adopted for being connected with a rotating shaft and a bearing seat in a rotating tire tool, high-pressure oil is injected into an oil cylinder to jack up a rotor spider, in a pressure maintaining state, a workpiece is rotated, when a main stud needing to be machined faces to boring machine equipment, the oil pressure is released, and the rotor spider slowly falls on a cushion cylinder at the equal altitude of a base of the rotating tire along with the decrease of the oil pressure. The processing method can be used for solving the difficult problem that the main stud cannot be integrally machined as the weight and external diameter of the rotor spider are too large, and meanwhile the processing method is high in precision of machining quality, strong in bearing capacity, high in production efficiency, and applicable to the machining of the main studs of the large and medium-sized rotor spiders, and has very high popularization and application values.

Description

technical field [0001] The invention relates to a process method for processing main vertical ribs of a large and medium-sized rotor support by using a rotating tire. Background technique [0002] As the capacity of the generator rotor bracket increases, its outer diameter and weight are designed to become larger and larger, and it is difficult to achieve accurate integral processing of the main vertical ribs on the machine tool. In the past, the center body and the support arm were processed in separate parts. After one set of support arms was processed, the crane lifted the support arm away from the other set of support arms, and the machine tool continued to combine the support arm and the center body. Align the workpiece, and then process this group of main ribs. In this way, the main vertical rib is processed circularly until all processing is completed. This conventional method has a long processing cycle and it is difficult to achieve the integrity of the main verti...

AI Technical Summary

Problems solved by technology

This conventional method has a long processing cycle and it is difficult to achieve the integrity of the main vertical ribs of the rotor bracket. When planing the auxiliary vertical ribs on the construction site, the adjustment workload is large and it is difficult to match and process, which is very unfavorable to the stacking of the rotor yoke , and even affect the rotor balance
