System for detecting mass, mass center and mass offcenter of cylinder

Abstract

The invention provides a system for detecting mass, mass center and mass offcenter of a cylinder, and belongs to the measurement technical field. The system for detecting the mass, the mass center and the mass offcenter of the cylinder comprises a main controller, a data acquisition module, a control interface module, a signal conditioning circuit, a motor driving circuit, a distance measuring device, a power module, a lifting motor, four weighting sensors and a lifting platform. The cylinder to be measured is clamped on a tray at one time, the lifting motor is started, the tray is landed on the weighting sensors, the distance measuring device is moved to measure a reference distance of the cylinder, and then data of the sensors are acquired twice in a front and back mode when the cylinder rotates by 90 degrees, and a detecting result of the mass, the mass center and the mass eccentricity of the cylinder can be acquired according to a four-point method. The system for detecting the mass, the mass center and the mass offcenter of the cylinder has the advantages of being compact in structure, large in measuring diameter range, high in measuring accuracy and automation degree, and capable of being used in delivery detection, factory acceptance inspection and quality characteristic detection of cylinder parts or products.

Description

technical field [0001] The invention relates to a detection system for mass, center of mass and mass eccentricity, especially suitable for detecting cylindrical components. It belongs to the field of measurement technology. Background technique [0002] Mass, center of mass, and mass deviation are parameters that often need to be tested during part processing and workpiece delivery, especially the quality characteristics of cylindrical components when they are filled or cast are directly related to the use effect, and some even play a decisive role. Detection of centroid and mass eccentricity is necessary to ensure good overall performance. Therefore, it is necessary to develop mass, centroid, and mass eccentricity detection equipment suitable for cylindrical graphs. Centroid detection involves measurement accuracy and measurement benchmarks. Currently, there are some similar algorithms, such as four-point method, three-point method, etc., to obtain the center of mass and ...
