我厂有多台无心磨床,都是手动进给,工人劳动强度大,生产效率也低。后来改成液压进给,效果较好,很受工人欢迎。M1080无心磨床的液压原理(图1)工人把工件放入导板上后,用脚踏上开关,电磁铁DT有电,高压油经两位四通阀进入油缸左腔,活塞推动齿条向右移动,通过齿轮(与进给丝杠固定)使丝杠回转一定角度,达到进给目的。 I plant more than one centerless grinding machine, are manually fed, workers labor-intensive, low productivity. Later into a hydraulic feed, the effect is better, very popular with workers. M1080 centerless grinder hydraulic principle (Figure 1) After the workers put the workpiece on the guide plate, with the pedal on the switch, electromagnet DT have electricity, high pressure oil through the two four-way valve into the left chamber of the cylinder, the piston pushes the rack to the right Move, through the gear (fixed with the feed screw) to screw a certain angle, to feed the purpose.
