最近我们设计制造了一种通用可调整液压虎钳,作为铣床的辅助工具,用于中小型工件。铣切平面或槽子等工序。经一年多的使用证明,这种液压虎钳性能良好,和机械虎钳比较,操作简便,省时省力,提高工效4～6倍。虎钳结构如图1示,两个钳口5分别安装在固定钳座3和活动钳座6上。固定钳座3以导槽和键块14定位安装在底座1上;活动钳座6在活塞7的推动下,沿着导槽可以在底座1上来回滑动,从而将工件夹紧或松开。夹 Recently, we designed and manufactured a universal adjustable hydraulic vise as an auxiliary tool for milling machines for small and medium-sized workpieces. Milling plane or slot and other processes. After more than a year of use proved that this hydraulic vise performance is good, compared with mechanical vices, easy to operate, save time and effort, improve efficiency 4 to 6 times. Vise structure shown in Figure 1, the two jaws 5 were mounted on the fixed jaw seat 3 and movable jaw seat 6. The fixed jaw base 3 is positioned and mounted on the base 1 by the guide groove and the key block 14; the movable jaw base 6 can be slid on the base 1 along the guide slot by the piston 7 to clamp or release the workpiece. folder
