斜度零件通常都是在正弦规上磨削加工,这时,影响斜度的因素有两个,一个是正弦规本身的仰角,另一个是零件在正弦规上的安装偏角。对双斜度的零件,只要通过计算,使仰角和偏角构成适当的配合,就可以在单层正弦规上,通过一次装夹和一次磨削,同时保证两个方向上的斜度都符合要求。如图1所示,当正弦规用量块垫起一个仰角a后,在x—x′截面内仰角为a,而Ⅰ—Ⅰ′截面内的仰角A_1可
Slope parts are usually ground on a sine gauge. There are two factors that affect the slope. One is the elevation angle of the sine gauge itself and the other is the mounting angle of the part on the sine gauge. For double-slope parts, once calculated, the elevation angle and the declination angle are properly matched to allow for clamping and grinding on a single-layer sinusoidal gauge, while ensuring that the inclinations in both directions are consistent Claim. As shown in Fig. 1, when the sine gauge is padded at an elevation angle a, the elevation angle in the x-x ’cross section is a, and the elevation angle A_1 in the cross section I-I’
