在普通摇臂钻床上,对工件上沿圆周均布的垂直孔或斜孔,能否实现半自动钻孔?经研究和实践。只需在钻床上设计制造一个附件作控制机构,并设计相应的带有动力装置(如气缸)的钻模,便能实现。图1是这种机构的原理框图。例如,现有图2所示的工件,要加工沿圆周均布的200孔。我们根据图1所示的原理,设计并制造了如图3的附件和钻模,成功地实现了半自动钻孔,达到了技术要求;且既大大减轻了操作工人的劳动强度,又较普通分度钻模加工,提高工效5倍以上。一、控制机构的作用原理和组成控制机构的作用是使钻模上分度气缸中的活塞,按加工要求作往复运动,并最终控制分度盘按加工要求自动分度。控制机构由卡箍1、安装杆2、棘爪3、棘轮13、
In ordinary rocker drilling machine, the workpiece is evenly distributed along the circumference of the vertical hole or inclined hole, can achieve semi-automatic drilling? After research and practice. Simply by designing and manufacturing an attachment for the control mechanism on the drilling machine and designing the corresponding die with the power unit (eg cylinder), this can be achieved. Figure 1 is a block diagram of this mechanism. For example, the existing workpiece shown in Figure 2, to be processed along the circumference of 200 holes. According to the principle shown in Figure 1, we designed and manufactured the attachments and drills as shown in Figure 3, successfully achieved the semi-automatic drilling and met the technical requirements. It not only greatly reduced the labor intensity of the operators, Degree drilling process, improve work efficiency 5 times. First, the role of the control mechanism and composition The role of the control mechanism is to drill on the cylinder indexing piston, according to the processing requirements for reciprocating motion, and ultimately control the indexing plate according to the processing requirements of automatic indexing. The control mechanism consists of a clamp 1, a mounting rod 2, a pawl 3, a ratchet 13,
