目前,在普通车床上使用的各种车刀,如需调整车刀刀尖安装高度,使其与主轴中心线等高,一般都是在车刀刀体下面加垫若干不同厚度的铁皮来达到,这不仅需要花较多的时间,操作颇感麻烦,对刀精度也不高,影响了工作效率。为解决这个问题,设计了一种可以调整车刀刀尖安装高度的组合车刀(图1)。该车刀上部刀体1与垫块2在各自的斜面上,以均匀布满的三角形小齿相互结合,用螺钉3将其紧固。制造时选取不同的斜角α和不同的齿距 S(图2),便可
At present, all kinds of lathe tools used in ordinary lathe, such as the need to adjust the tooling tool nose installation height, so that it is the same as the centerline of the spindle, usually under the knife body plus a number of different thickness of metal to achieve , Which not only takes more time, the operation is quite troublesome, the knife accuracy is not high, affecting the work efficiency. To solve this problem, we designed a combination turning tool that can adjust the installation height of the lathe tool tip (Fig. 1). The upper tool body 1 of the turning tool and the spacer 2 are combined with triangular shaped small teeth evenly distributed on the respective inclined surfaces and fastened by screws 3. Select a different manufacturing angle bevel α and different pitch S (Figure 2), you can
