机夹硬质合金可转位多边形刀片的装配式车刀与焊接式车刀比较有一系列优点,但是对于每种形式和尺寸的切削刀片都需要特定的刀杆,其刀槽也要与所用刀片的形状和尺寸精确地相符。为了减少可转位装配式刀具的品种与数量,苏联库尔干机械学院研制出一种附图所示的通用装配式车刀。它由可转位刀头1、可换刀座3、质合金支承片4、切削刀片5、钩形压板6、扇形齿板11和刀杆本体14等组成。刀座用螺钉2固定在刀头上,而刀座的形状须与支承 Machine-mounted carbide indexable polygon inserts have a number of advantages over assembly and welding tools, but they require a specific shank for each form and size of cutting insert, The shape and size exactly match. In order to reduce the variety and number of indexable assembly tools, the Soviet Union Kurgan Institute of Mechanical developed a general-purpose assembly tool shown in the attached figure. The utility model is composed of an indexable cutter head 1, a tool changeable seat 3, a quality alloy support piece 4, a cutting blade 5, a hook-shaped pressure plate 6, a toothed plate 11, an arbor body 14 and the like. The knife holder is fixed to the cutter head with a screw 2, and the shape of the knife holder is to be supported
