Standard Calibration Rotor for Dynamic Balancing Machine with Inner Taper

Abstract

The invention discloses a dynamic balancing machine standard correction rotor with an internal conical surface. The dynamic balancing machine standard correction rotor comprises a central spindle, wherein the central spindle comprises a left supporting section supported on a balancing machine bearing bracket, an interference fit section in interference fit with a central hole in a left end cover, a limiting section for performing axial limiting, a clearance fit section in clearance fit with a central hole in a right end cover, a threaded section matched with a locking nut and a right supporting section from the left to the right, wherein assembling rings are formed on the opposite end surfaces of the left end cover and the right end cover; the inner ring of each assembling ring is a conical surface; and multiple threaded holes matched with a test mass are formed in the radial direction of the assembling rings. According to the left end cover and right end cover with internal conical surfaces as well as the threaded holes in the assembling rings, real-time correction of a dynamic balancing machine is realized, and due to a chamber structure of the internal conical surface, a composite material cylinder can be subjected to line contact positioning, so that a measuring error introduced by the processing quality of the cylindrical end surface can be effectively avoided, and the system measuring error brought by the initial unbalance quantity of a positioning tool is reduced to the greatest degree.

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 inner 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 made of filament winding, whether the winding is uniform or not, and the shape and position error after machining will directly affect the imbalance of the cylinder, 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 device for dynamic balancing. In order to meet the real-time calibration of the dynamic balancing machine, it is necessary to design a device that can simultaneously satisfy the cylinder dynamic balance detection and positioning and balancing machine c...
