Abstract

Disclosed in the invention is an external-conical-surface-contained standard calibration rotor for a dynamic balancing machine. The calibration rotor comprises a mandrel including a left support segment, an interference fit segment, a limiting segment, a clearance fit segment, a thread segment, and a right support segment from left to right; the left support segment is supported at a balancing machine bearing rack; the interference fit segment is in an interference fit relation with a center of a left end cover; the limiting segment is in an axial limiting mode; the clearance fit segment is in a clearance fit relation with a center of a right end cover; and the thread segment cooperates with a locking nut. Assembling rings are formed on opposite end surfaces of the left end cover and the right end cover; and limiting plates are formed on the outer walls. The outer rings of the assembling rings are conical surfaces; and a plurality of threaded holes cooperating with a test mass unit are formed in the assembling rings in the radial direction. According to the invention, with the left end cover having the external conical surface and the right end cover having the external conical surface as well as threaded holes arranged on the assembling rings, real-time calibration of the dynamic balancing machine is realized; and with the external conical surfaces and the limiting plates, line-contact positioning is carried out on a composite-material-based cylinder, thereby minimizing a system measurement error caused by the initial unbalancing value of the positioning tool itself.

Description

Technical field [0001] The invention belongs to a calibration device, in particular to a standard calibration rotor of a dynamic balancing machine with an outer cone. Background technique [0002] The composite cylinder is a part of high-speed rotating machinery, and its initial imbalance will directly affect its radial vibration amplitude. This kind of cylinder is wound by filaments. Whether the winding is uniform and the size of the shape and position error after machining will directly affect the size of the cylinder's imbalance, and then affect the performance of the whole machine after assembly. In order to accurately measure the initial unbalanced mass of the cylinder, it is necessary to design a special auxiliary positioning tool to dynamically balance it. In order to meet the real-time calibration of the dynamic balancing machine, it is necessary to design a device that can simultaneously meet the cylinder dynamic balance detection positioning and balancing machine calibr...
