Description

一种旋转编码器的零位调整装置及其使用方法A zero position adjustment device for a rotary encoder and its application method

技术领域 technical field

本发明涉及机械自动化控制的领域,特别涉及一种自动控制机构的旋转编码器的零位调整装置及其使用方法。 The invention relates to the field of mechanical automation control, in particular to a zero position adjustment device of a rotary encoder of an automatic control mechanism and a use method thereof.

背景技术 Background technique

一般带转轴的自动控制机构在使用过程中需利用旋转编码器检测转轴的角度,当转轴角度为特殊值时(通常为零位置)自动控制机构某一零件运动到某一特殊位置,即机构运动到该位置时,与转轴同轴旋转的旋转编码器正好输出零位信号;自动控制机构上的旋转编码器的安装方式:所述旋转编码器的空心转轴与被测自动控制机构的转轴传动相连;旋转编码器的壳体通过一弹性支架设于所述被测自动控制机构的安装板上。 Generally, an automatic control mechanism with a rotating shaft needs to use a rotary encoder to detect the angle of the rotating shaft during use. When the angle of the rotating shaft is a special value (usually zero position), a part of the automatic control mechanism moves to a special position, that is, the mechanism When moving to this position, the rotary encoder rotating coaxially with the rotating shaft just outputs a zero position signal; the installation method of the rotary encoder on the automatic control mechanism: the hollow rotating shaft of the rotary encoder is driven by the rotating shaft of the automatic control mechanism under test. connected; the housing of the rotary encoder is set on the mounting plate of the automatic control mechanism under test through an elastic bracket.

为了使旋转编码器的输出信号与自动控制机构的转轴协同,带转轴的自动控制机构在工作前一般需要把旋转编码器先回到零点,作为工作起点。 In order to coordinate the output signal of the rotary encoder with the rotating shaft of the automatic control mechanism, the automatic control mechanism with a rotating shaft generally needs to return the rotary encoder to the zero point before working as the starting point of the work.

由于旋转编码器在安装过程中可能停在圆周方向任意位置,通常为了使旋转编码器能停靠在零位,一般需要断开编码器转轴与机构转轴的连接(编码器转轴可旋转,而机构转轴不动),手工转动编码器转轴直到输出零位信号为止,由于同时需要将所述旋转编码器的空心转轴与被测自动控制机构的转轴固定相连,因此不易控制其精度。即:传统的手工调整方法很难把编码器转轴快速、准确、可靠地停在零位。 Since the rotary encoder may stop at any position in the circumferential direction during installation, usually in order to make the rotary encoder stop at the zero position, it is generally necessary to disconnect the encoder shaft from the mechanism shaft (the encoder shaft can rotate, and the mechanism shaft do not move), and manually rotate the encoder shaft until the zero signal is output. At the same time, the hollow shaft of the rotary encoder needs to be fixedly connected with the shaft of the automatic control mechanism under test, so it is difficult to control its accuracy. That is: the traditional manual adjustment method is difficult to quickly, accurately and reliably stop the encoder shaft at zero.
