最近,我们设计了深孔内球面车削装置,加工了一批深孔球面零件(见图1),取得了理想效果,现介绍如下: 深孔内球面车削装置结构如图2所示,它由刀杆1、蜗杆2、蜗轮3、轴4、刀座7等组成。设计要求:刀具能在圆周内转动90°,且能满足工件圆弧面半径的尺寸要求。因采用蜗轮副、切削时无明显振动、窜动现象。 加工刀座扇形块时,扇形半径.尺寸很重要,因为它是调整刀子尺寸的基准。 操作时,工件装夹在车床卡盘上,当孔加工到一定的尺寸后,把深孔球面车削装置安装在刀架的正前方,调整好刀具的尺寸,进行切削。当走刀到圆柱面和球面相接触处时,停止走刀。转动手柄,切削球面,当刀具转动90°后停止转动手柄,将刀退出,如需再 Recently, we have designed deep-hole spherical turning device, processing a number of deep-hole spherical parts (see Figure 1), and achieved the desired effect, are described below: Deep-hole spherical turning device structure shown in Figure 2, which consists of Arbor 1, worm 2, worm 3, shaft 4, knife seat 7 and other components. Design requirements: the tool can rotate 90 ° in the circle, and can meet the size requirements of the arc radius of the workpiece. Due to the use of worm gear, cutting no significant vibration, the phenomenon of movement. The radius of the fan when machining the block of the cutter. The size is important because it is the base for adjusting the size of the knife. During operation, the workpiece is clamped on the lathe chuck. When the hole is machined to a certain size, the deep-hole spherical turning device is installed in front of the tool holder, and the size of the tool is adjusted and cut. When the knife to the cylindrical surface and spherical contact at the time, stop the knife. Rotate the handle, cutting the spherical surface, when the tool turns 90 °, stop turning the handle, the knife out, if you want
