Abstract

The invention relates to a tool for repairing and grinding center holes of an output shaft of an aero-engine and a repairing and grinding work method of the tool. The tool comprises rolling rods, aninner taper sleeve, an outer taper sleeve, a pressing plate and a screw, wherein the rolling rods are arranged and placed in a spline groove of the output shaft at equal intervals in a circumferentialmode, an inner hole of the inner taper sleeve is in contact compression with the rolling rods, and the inner conical surface of the outer taper sleeve is compressed with the outer conical surface ofthe inner taper sleeve in a cooperating mode; and the left end face of the pressing plate is in contact compression with the right end face of the inner taper sleeve, the screw penetrates through a through hole in the pressing plate and is in threaded connection with a threaded hole in the end face of the inner taper sleeve. The tool is simple in structure and easy to machine; according to the repairing and grinding work method of the tool, manual hand scraping repairing and grinding in the prior art is replaced by machining repairing and grinding, so that instability of manual repairing and grinding is eliminated, and the phenomenon that the output shaft is damaged by a hand scraper in the manual repairing and grinding process can be effectively avoided; and the repairing and grinding working method of the tool is simple, convenient and reliable, and on the premise of guaranteeing the repairing and grinding quality, the time required for repairing and grinding is shortened.

Description

technical field [0001] The invention relates to a tooling for repairing and researching, in particular to a tooling for repairing and researching a center hole of an output shaft of an aeroengine and a repairing and researching working method thereof. Background technique [0002] The engine output shaft is the power output device of the engine, which has the characteristics of high precision requirements, high surface quality requirements, and consistent wall thickness. In order to ensure the above quality requirements, the processing technology of the output shaft needs to be processed by double-top clamping method , the above-mentioned double-top clamping method requires pre-machining a center hole at both ends of the output shaft. The center hole is the process hole processed to determine the center of the workpiece. The center hole is used as the positioning reference of the workpiece and bears the weight and cutting force of the workpiece. , so the processing quality o...
