摘要
为了使旋转编码器安装时在零位,设计了找零位装置,该装置包括电子手轮、步进电机、蜗杆、斜齿轮和磁力表座组件。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。电子手轮输出信号接入步进电机驱动器,步进电机跟随电子手轮转动进而驱动蜗杆转动,蜗杆驱动斜齿轮,进而驱动旋转编码器空心转轴;同时计算机读取旋转编码器输出信号以判断其是否在零位,如在零位,则立刻停止转动电子手轮。实验结果表明:利用该装置可方便、快捷地把旋转编码器安装在零位。
The adjustment device was designed in order that rotary encoder could be installed at zero position.The adjustment device was composed of a electronic handwheel,a step motor,a helical gear,a worm and a magnetic table block.The helical gear was installed on hollow shaft of rotary encoder,the magnetic table block was fixed on automated equipment by means of magnetic suction,the worm was installed in axle sleeve,which was clamped in elastic hole chuck of the magnetic table block.Output signals of the electronic handwheel was connected to step motor driver,the worm was driven by the step motor,which rotated following the electronic handwheel.The helical gear was driven by the worm,the hollow shaft of rotary encoder was driven by the helical gear.At the same time,output signals of the rotary encoder was read by software and used to judge whether the rotary encoder was at zero position.The rotation of the electronic handwheel was stopped immediately if the rotary encoder was at zero position.Experimental results show that the rotary encoder can be installed at zero position efficiently and easily with the adjustment device.
