西德博尔肯市福克(FOOKE)公司机械厂推出了一种磨头用液压夹紧装置。该装置由磨头的定位部分,压盖、液压螺帽以及一个专门的液压机组成。如图所示,定位部分(a)通过机械套筒调整并带有锯齿形螺纹。用手或借助于磨头调换装置装上砂轮(b)后,放上压盖(c),再用手将带液压缸的压紧螺帽(d)旋紧。借助一台液压机,一组轴向工作活塞在环形方向的10孔上均衡地压紧压盖的背面,借此消除水平倾角
FOOKE, West Balkans, has introduced a hydraulic clamping device for grinding head. The device consists of the positioning part of the grinding head, gland, hydraulic nut and a special hydraulic machine. As shown, the positioning section (a) is adjusted by the mechanical sleeve and has a zigzag thread. After attaching the grinding wheel (b) by hand or with the aid of a head changer, place the gland (c) and tighten the compression nut (d) with the cylinder by hand. With a hydraulic press, a set of axially acting pistons press the back of the gland evenly over 10 holes in the ring direction, thereby eliminating the horizontal inclination
