在生产中,经常遇到一些曲线零件的车削加工,在没有专用机床的情况下,利用普通车床进行加工是很困难的。为此,我们对车床进行了改进,采用仿型刀架,效果很好。仿型刀架的结构见图1。底托1与活动刀夹2用燕尾配合,间隙用镶条8调整,挡板4固定在底托1后边,压缩弹簧3对活动刀夹2产生向前的推力,底托 In production, often encounter some curved parts of the turning process, in the absence of special machine tools, the use of ordinary lathe for processing is very difficult. To this end, we have improved the lathe, the use of imitation tool holder, the effect is very good. Figure 1 turret structure. The bottom bracket 1 and the movable blade holder 2 are matched with a dovetail, the gap is adjusted by the insert strip 8, the baffle plate 4 is fixed behind the bottom bracket 1, the compression spring 3 generates a forward thrust to the movable tool holder 2,
