旋转编码器安装至零位调整装置研制

Research on adjustment device for rotary encoder to be installed at zero position

为了使旋转编码器安装时在零位,设计了零位调整装置。该装置包括:斜齿轮、蜗杆和磁力表座组件。斜齿轮安装在旋转编码器的空心转轴上;磁力表座组件依靠磁铁吸力固定在自动化设备上,蜗杆安装在轴套中,该轴套被夹在磁力表座组件的弹性孔夹头中。蜗杆发生转动时驱动斜齿轮,进而驱动旋转编码器空心转轴,同时计算机软件读取旋转编码器输出信号以判断其是否到达零位,如在零位,则停止转动蜗杆。实验结果表明:使用该装置可方便、快捷地把旋转编码器安装在零位。

The adjustment device is designed in order that rotary encoder can be installed at zero position The ad- justment device is composed of a helical gear, a worm and magnetic table block. The helical gear is in- stalled on hollow shaft of rotary encoder, the magnetic table block is fixed on automated equipment by means of magnetic suction, and the worm is intalled in axle sleeve, which is clamped in elastic hole chuck of the magnetic table block. The helical gear is drived by the worm, the hollow shaft of rotary en- coder is driven by helical gear. Output signals of the rotary encoder is read by software and used to judge whether the rotary encoder is at zero position. The rotation of the worm is stop immediately if the rotary encoder is at zero position. The result of experiment shows that the rotary encoder can be installed at zero position efficiently and easily by means of the adjustment device.
