为尽快对现有普通车床进行数控改造,本文介绍一种螺旋槽式自动转位刀架。这种刀架(见图1)具有定位准确、结构简单、使用方便、转位时间短、体积小、重量轻、经济性好等优点。 1.工作原理 为实现自动转位换刀,刀架可完成松开—抬起—转位—落下—定位—夹紧几个动作。如图1所示,电机通过蜗杆1,蜗轮2,使带有螺旋槽的轴6转动。螺旋槽通过抬起销7使刀架体8抬起,至所控制位置
As soon as possible to the existing ordinary lathe CNC transformation, this article describes a spiral groove automatic indexing turret. This knife holder (see Figure 1) has the advantages of accurate positioning, simple structure, easy to use, short indexing time, small size, light weight and good economy. 1 working principle To achieve automatic indexing tool change, the turret can be completed Loosen - lift - indexing - fall - positioning - a few clamping action. As shown in FIG. 1, the motor rotates the shaft 6 with the spiral groove through the worm 1 and the worm wheel 2. The spiral groove lifts the knife body 8 up to the controlled position by lifting the pin 7
