轉臺校準用精密角度分度系統設計(中文3700字,英文2500字)
摘要
分度臺是為機床上的角度測量而開發的。本文所述的測量技術目前在制造工程中可用于校準角度測量。概述了每種設備的測量原理,并討論了其功能。設計并制造了使用6點運動學概念和使用球和V形槽位置的新分度臺,以使用激光干涉儀校準旋轉臺的角度誤差。評估制造方法以制造精確的V形槽。設計和制造了一個特殊的凸輪,以便將旋轉運動轉換成提升和旋轉運動。CNC加工中心和分度頭用于制造凸輪。新的分度臺的所有部件均按制造公差制造,按照圖紙,方形和平行度檢查,以遵守6點運動學概念。而且這些因素控制著新分度臺的可重復性。在安裝新的分度臺之后,使用在水平和垂直方向操作的旋轉工作臺來評估性能。

Design of precision angular indexing system for calibration of rotary tables†
Mechatronics & Manufacturing Center, Samsung Electronics Co. LTD., Suwon-city, 443-742, Korea
Abstract
The indexing table was developed for angle measurements on machine tools. The measuring techniques, which have been reviewed in this paper, are currently available in manufacturing engineering to calibrate the angle measurement. The measuring principles of each equipment are outlined and their capabilities are also discussed. The new indexing table using 6 points kinematic concept and employing ball and vee grooves location was designed and manufactured to calibrate angle errors of rotary tables using a laser interferometer. The manufacturing method was evaluated to manufacture the accurate vee grooves. A special cam was designed and manufactured to trans-late rotation movement into lift-up and rotation movement. A CNC machining centre and indexing head were used to manufacture the cam. All parts of the new indexing table were manufactured with a manufacturing tolerance according to drawings, squareness and paral-lelism checked to obey the 6 points kinematic concept. Also these factors controlled the repeatability of the new indexing table. After installing the new indexing table, the performance was evaluated using rotary table operating in both the horizontal and vertical orienta-tions.
