组合机床的加工精度取决于动力部件的刚度。 刚度是由作用力与由它引起的变形量之间的比值来确定的。文章介绍了组合机床动力滑台刚度的计算方法。通过计算得知,对滑台刚性影响最大的是由轴向载荷造成的垂直面内的弯曲变形,扭矩对滑台刚性影响不大。图3幅。
The machining accuracy of a combined machine depends on the stiffness of the power unit. Stiffness is determined by the ratio of the force to the amount of deformation caused by it. The paper introduces the calculation method of combined machine tool dynamic stiffness. It is found by calculation that the most significant influence on the rigidity of the sliding table is the bending deformation in the vertical plane caused by the axial load, and the torque has little effect on the rigidity of the sliding table.
