日本电产机床研发出新款直线位置检测器“MPLW系列(暂称)” 维持传统性能的同时实现新功能、低价格

采用新设计,不再需要光栅尺接线和模拟/数字转换器

日本电产机床株式会社新研发出了可对机器的定位和进给量等进行数字化检测的电磁感应式直线位置检测器“MPLW系列”。其不仅具有与传统的MPLZ系列相同的分辨率※1和精度,还通过新开发的信号检测方法和基板的高度集成化,取消了光栅接线及模拟/数字转换器(以下简称A/D转换器)的使用,新增了可设置多个滑块的多滑块功能,并实现了低廉的产品供价。日本电产机床计划从今年秋季开始向以机床为代表的工业机械领域市场进行推广。

MPLW系列是用于一般机器的、直线轴位置检测分辨率为0.01μm、节距精度为25μm的高精度光栅尺。传统的MPLZ系列在目标机器上安装了光栅尺和滑块,从双方连接配线,并通过NC (数控) 装置收发电气信号。此次,日本电产机床开发了一种新的检测模式*3,可以在不相互干扰的情况下接收来自光栅尺的电气信号,并且通过这种信号检测方法取消了光栅接线。此外,将来自于光栅尺的电气信号转换为数字信号的A/D转换器的功能是内置在滑块中的,因此可以实现基板的高度集成,并且可以仅使用光栅尺和滑块实现机器的控制装置以及信号的收发。这些技术的研发取消了光栅尺接线和A/D转换器,从而减少了部品数量和制造工序,并大大简化了客户方的安装作业。此外,日本电产机床还新增了多滑块功能,可以在一根光栅尺上设置多个滑块,应对多种用途。

MPLW系列的最大特点是电磁感应技术具有出色的耐用性,其检测精度不受灰尘、油污和结露的影响。此外,完全非接触结构具有长期稳定维持精度、不易受热影响等特点,受到多个工业领域的青睐。

本公司今后将继续运用机床相关的技术以及日本电产集团的马达相关技术和全球网络,不断推进新产品的研发,以更好地满足广大客户的需求。

※1分辨率:将物理量作为测量值表示的最小单位。
※2节距精度:在1m范围内的最大误差量。
※3检测模式:光栅尺和滑块表面上的铜箔形状。
