Field honing system with guiding rail and method for steam turbine rotor coupling nut hole

Abstract

The invention discloses a field honing system with a guiding rail and method for a steam turbine rotor coupling nut hole. The field honing system mainly comprises a guiding rail assembly, a driving tool and a honing tool. The guiding rail assembly is composed of the guide rail, a sliding block and an installing base plate. The driving tool composed of a power unit and a driving unit is installed on the guiding rail assembly to drive the honing tool, feeding is conducted manually or automatically, and grinding work of the steam turbine rotor coupling nut hole is completed. The driving tool andthe honing tool are connected through a coupling B and a coupling A. The coupling B and the coupling A adopt each adopt a universal or floating connection structure. The honing tool is installed to beof two kinds of structures of center arrangement installation and offset installation relative to the guiding rail assembly. The field honing system has the beneficial effects that the field honing system meets the requirement of a narrow field construction space of a power plant, the working difficulty of operators is reduced, and the machining reliability is enhanced.

Description

technical field [0001] The invention belongs to the field of machining tools for steam turbine rotor counter-wheel bolt holes, and mainly relates to an on-site honing system and method for steam turbine rotor counter-wheel bolt holes with guide rails. Background technique [0002] The bolt holes of the steam turbine rotor and wheel need to be finished on site, and the on-site honing method is generally used. It involves the design and selection of honing tools, drive units and power units. In the past, a hand-held power unit was used to drive the honing tool for processing, resulting in the processed holes being elliptical, drum-shaped, and bell-mouthed. At the same time, the labor intensity of the operators was high, and the operators required a high level of professionalism. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a system and method for on-site honing of bolt holes of the steam...
