Rotating Body Balance Observation Using Angle-Deviation Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy of observing and correcting the balance state of a rotating body in a machine tool is inconsistent due to the dependency on the installation method and position of the field balancer, making it difficult to achieve stable and precise balance correction.
Innovation Solution
An observation device and method that include a detector to measure the angle of rotation, a moving body to compensate for positional deviations, and a system to store and display the relationship between compensated angles of rotation and positional deviations, allowing for accurate balance correction without a field balancer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a field balancer is installed to measure the balance state of a rotating body, then the balance state can be observed, but the accuracy becomes inconsistent due to dependency on installation method and position
Solution Approach 1:
The patent replaces the mechanical field balancer system with an observation device that uses a detector to measure the angle of rotation and a control device to calculate positional deviations. This substitution eliminates the need for mechanical installation of a field balancer on the rotating body, thereby removing the source of measurement inconsistency while maintaining the ability to observe balance state accurately and reliably.
2Manufacturing precision
If a field balancer is used for balance correction, then the balance state can be corrected, but the correction accuracy is difficult to maintain stably and consistently
Solution Approach 1:
The patent implements a feedback mechanism where the detector continuously monitors the angle of rotation of the rotating body, and the control device uses this information to calculate positional deviations and guide balance correction. This closed-loop feedback system ensures that balance correction can be performed with stable and consistent accuracy, as the system continuously adjusts based on actual measured data rather than relying on manual field balancer operations.
3Ease of operation
If the detector installation position is not predetermined, then installation flexibility is improved, but measurement accuracy becomes inconsistent
Solution Approach 1:
The patent requires that the detector be installed at a predetermined position on the rotating body before measurement begins. This preliminary positioning action ensures that the angle of rotation can be measured accurately and consistently. The control device then uses this predetermined installation position as a reference to calculate positional deviations, thereby maintaining measurement precision while still allowing flexibility in where the predetermined position is located on the rotating body.

AI summary
This observation device includes a command output unit that rotates a rotation part and stops a moving body; a first acquisition unit that acquires the rotation angle of the rotation part; a second acquisition unit that acquires the positional deviation of the moving body; a correction unit that corrects the rotation angle on the basis of an angle difference; a second storage control unit that establishes a correspondence between the rotation angle and the positional deviation; and a display control unit that displays, on a display unit, a graph indicating the correspondence between the rotation angle and the positional deviation.
