机床夹具设计过程中夹紧力的计算

在机床上加工零件时,为了保证加工精度,必须先对工件进行定位并将其夹紧。夹具夹紧力的作用主要是保证工件的定位基准与定位件保持良好的接触,使加工时不致于受切削力、离心力、惯性力及工件自重等作用而移位;夹紧力通过大小、作用点和方向来体现在夹具设计。

Calculation of the Clamping Force During the Design of Clamp of Machine Tool

The positioning and clamping of parts are necessary, aiming to ensure the processing accuracy. The clamping force can ensure the close contact between the work piece and positioning reference, aiming to avoid the movement by the cutting force, centrifugal force, inertial force, and its self-weight. The clamp design includes the level, point of action, and direction of the clamping force.
