本发明所涉及的是一种装有迥转工件轴及一个相应可调的迥转工具的光学透镜抛光用的气动测量、主动控制装置。一般的通过测量来控制的研磨机或抛光机都具有一个在加工范围内可旋转的测量弓形架,其测试装置在测量工件时,对一个和气动量仪相连接的挡板压力伐起影响作用。气动量仪压力计管中的液位高度随通过挡板压力伐的测量压力的改变而变化。液位高度的变化可在刻度盘上读出,并可利用一个能移动的光电测量头来将其转换成为电脉冲,在规定的公差范围内发出控制机床所需要的控制信号。然而这些结构都有缺点,就是说,要在瞬时加工位置上不中断加工过程去对要达到很高
The present invention relates to an aerodynamic measurement and active control device for polishing an optical lens equipped with a rotary work piece shaft and a correspondingly adjustable rotary tool. A typical metered or polished machine has a measuring bow that can be rotated within the machining range. The measuring unit of the measuring device influences the pressure of the baffle plate connected to the pneumatic gauge during the measurement of the workpiece . The level of the liquid level in the pneumatic gauge pressure gauge tube changes with the change in the measured pressure through the baffle pressure cut. The change in level can be read out of the dial and converted to an electrical pulse using a moveable photoelectric measuring head that sends the control signals required to control the machine within a specified tolerance. However, these constructions all have disadvantages, that is to say, it is necessary to achieve a high level of processing without interrupting the machining process at the instantaneous machining position
