A Study on a New Method for Measuring Positioning Accuracy of Multi-Station Turntable

Abstract:

Multi-station turntable, widely used in industrial automation field, has become an indispensable device in the automation assembly line. The positioning accuracy of traditional mechanical turntable is largely affected by the machining accuracy of Geneva wheel, Ratchet and Cam. The positioning accuracy level has a crucial influence on processing and assembly accuracy, and production efficiency. This paper presents a measuring method to measure positioning accuracy by eddy current sensor. To achieve the positioning accuracy the writer measures the distance between the probe and the measuring block in the circumferential tangent direction. When the turntable turns to a station, the sensor probe is manually adjusted to align it with the measuring block. In this way, the positioning accuracy can be measured conveniently and directly.
