移动装卡式小型摇臂钻床适用在起重设备不足的条件下,对大型工件钻孔用。实践证明,这种钻床的工效可超过一般钻床,平均每班可钻孔250个以上,最高可达420个左右。二、结构及使用方法:机床结构很简单(如图1)。使用时,将小钻床用装卡机构24固定在工作物上。利用丝杠6将摇臂22提升(或降落)到需要的高度(摇臂22的摆动靠手推动)。转动手轮18,通过连动的小齿轮与齿条21啮合,使滑板18a沿摇臂方向移动。调整钻头对准钻模孔。手柄23用以夹紧摇臂;滑板则靠手柄20固紧。
Mobile loading small radial rocker drilling machine applicable to the lack of lifting equipment under the conditions of drilling large workpieces. Practice has proved that the ergonomics of this drilling machine can exceed the average drilling machine, the average class can be drilled more than 250, up to 420 or so. Second, the structure and use: The machine tool structure is very simple (Figure 1). When used, the small drill chucking mechanism 24 is fixed on the work piece. The rocker arm 22 is lifted (or lowered) to the required height by the lead screw 6 (rocking arm 22 is pushed by hand). The handwheel 18 is rotated to mesh with the rack 21 via the interlocking pinion to move the sliding plate 18a in the direction of the rocker arm. Adjust drill to drill hole. The handle 23 is used for clamping the rocker arm; the sliding plate is fastened by the handle 20.
