在生产中,我们完成了一种具有大型内球面圆弧零件的加工任务;工件要求加工出φ1600_(+0.3)~0的内圆弧球面,为此,我们在C551J立式车床上安装了一套车削装置,较满意地完成了加工任务,现将装置及工作原理介绍如下: 车削装置(见图1)为具有一个固定支点的杠杆机构。先在车床左刀杆下端装上两个定位板,装置的中间支点则由销轴铰链联接在定位板下部的水平孔内,杠杆两端绕支点可作圆弧运动,而在车床右刀杆下则装一拉杆,用它来拖动连杆并传动杠杆右端运动,加工时由车床右刀杆作垂直进给,由于拉杆及连杆传动,使杠杆左端安装的车刀也作相
In the production, we have completed a machining task with a large inner spherical arc part; the workpiece requires the processing of the inner circular arc of φ1600 _ (+0.3) ~ 0, for which we installed a C551J vertical lathe Set of turning devices, more satisfied with the completion of the processing tasks, now the device and working principle is introduced as follows: Turning device (see Figure 1) with a fixed fulcrum lever mechanism. The first left lathe knife lathe installed at the bottom of the two positioning plate, the device by the middle of the pivot hinge pin connected to the lower horizontal hole in the positioning plate, both ends of the lever can be used for circular arc around the fulcrum, The next is equipped with a rod, use it to drag the rod and drive the right end of the lever movement, processing by the lathe right knife for vertical feed, as the rod and connecting rod drive, so that the left lever lever installed for phase
