一、概述目前,设备上的精密分度,采用精密光学经纬仪或圓型感应同步器作为分度元件的数显装置,分度误差一般可达±2″。在大型分度转盘(设备)上,使用精密光学经纬仪或圆型感应同步器数显装置吋,若分度转盘直径达到φ10000mm,最大直径处,在圓周方向上产生的分度线性误差就会达到±0.049mm以上。显然,若想继续提高大型分度转盘的分变精度是有很多技术困难的。直线式感应同步器的滑尺和定尺在实际使用中,任何两点之间的综合误差,零级精度为0.0046mm。如果把零级精度的直线式感应同步器的滑尺和定尺能弧形安装在大型转盘上,包括各种安装误差在内,使
I. INTRODUCTION At present, the precision indexing on the equipment adopts the digital optical theodolite or the circular induction synchronizer as the digital display device of the indexing component, and the indexing error can generally reach ± 2 ". On the large indexing dial (equipment) , The use of precision optics theodolite or circular induction synchronizer digital display device, if the indexing turntable diameter φ10000mm, the maximum diameter at the circumference of the indexing linear error will produce ± 0.049mm or more. Obviously, if you want Continued to improve the large indexing turret variable precision is a lot of technical difficulties.Linear induction synchronizer slider and length in the actual use, any combination of any two errors, the zero-order accuracy of 0.0046mm. If The zero level accuracy of the linear induction synchronizer slide and the length of the arc can be installed on a large turntable, including a variety of installation errors, including the use of
