M9017光学曲线工具磨床是我厂在无产阶级文化大革命中设计和制造的。近几年来,据用户厂反映“该机床在操作中不易掌握”。为了提高磨削精度和操作灵敏度,我们针对用户厂的意见对机床的操作机构及液压系统进行了分析和研究,并作了改进。机床外观见图1。该机床采用大光屏及单手轮同时控制两座标方向的运动,具有正弦曲率变化的磨削形式。座标控制机构及工作原理如图2所示,由一个偏心凸轮同时控制互成90°的两个结构相同的流量分配阀K和Q,x和y两座标的进给速度和滑阀阀芯的移动量成正比,
M9017 optical curve tool grinding machine is our factory in the proletarian cultural revolution designed and manufactured. In recent years, according to the user plant reflects “the machine is not easy to grasp in the operation.” In order to improve the grinding precision and operation sensitivity, we analyzed and researched the operation mechanism and hydraulic system of the machine tool according to the opinions of the user’s factory and made improvements. Machine appearance shown in Figure 1. The machine uses a large light screen and single hand wheel while controlling the direction of the movement of the two coordinates, with a sinusoidal curvature changes in the form of grinding. Coordinate control mechanism and working principle shown in Figure 2, by an eccentric cam while controlling each other 90 ° two identical flow distribution valve K and Q, x and y coordinates of the two feed rate and the spool valve The amount of movement is proportional to,
