Rotor shaft machining tool and machining method

Abstract

The invention discloses a rotor shaft machining tool and machining method. The machining tool comprises a horizontally-arranged bottom plate, a vertical first positioning plate is arranged on the bottom plate, a clamping block matched with a key groove in a rotor shaft in an inserted mode is arranged on the right side surface of the first positioning plate, the bottom plate is also vertically provided with a second positioning plate located on the right side of the first positioning plate, the first positioning plate and the second positioning plate are arranged in a mode of directly facing towards each other at an interval, the upper end surface of the second positioning plate is provided with a vertical guide hole, the second positioning plate is provided with a receding hole allowing the rotor shaft to penetrate therethrough to be matched the clamping block in an inserted mode, the receding hole communicates with the guide hole, and the machining tool further comprises a fastening device which is arranged on the bottom plate, is located on the right side of the second positioning plate and is used for allowing the rotor shaft to be placed and tightly clamped. Through use of themachining tool, the machining process of the rotor shaft can be simplified, and the position accuracy between the key groove and a timing pin hole on the rotor shaft can be improved. Furthermore, theinvention further discloses the rotor shaft machining method so as to ensure that the rotor shaft machining tool is effectively used so as to generate a positive effect.

Description

Technical field [0001] This application relates to the technical field of generator rotor shafts, in particular to a rotor shaft processing tool and processing method. Background technique [0002] The rotor shaft is the shaft on which the rotor is installed in the generator. The generator drives the rotor shaft to rotate through an external power input to drive the rotor to rotate relative to the stator to cut the magnetic line of induction to generate electricity. The power input is generally a diesel or gasoline engine, and in actual use, the unit is required to ignite at a timing. [0003] To this end, the applicant discloses a timing ignition generator rotor shaft, the structure of which is as follows figure 1 Shown. One end of the shaft is provided with a key groove, and the other end is provided with a timing pin hole, wherein the axis of the timing pin hole is required to be located on the central symmetry plane of the key groove or the position error of the two is within ...

AI Technical Summary

Problems solved by technology

[0004] In actual processing, it is not easy to drill holes on the outer circular surface, and the drill bit is easy to miss. Secondly, it is difficult to ensure the position accuracy of the two during processing. The operation of the regular planning line is complicated, time-consuming and inefficient.

Moreover, manual marking and positioning are extremely easy to introduce human error, which increases the processing scrap rate
