一、非圆形轴车削用液压仿型设备的改装 1.概述大多数能在车床上加工的零件,其外形都是按车床主轴轴线对称分布的,如阶梯轴、特形轴(图1)等。这些零件的任一横截面都是一完整的圆形,但各横截面的半径却不一定相同(随轴的外形而变)。有些零件的外形则与车床主轴轴线不对称分布,其横截面为非圆形曲线,如凸轮轴、多角形轴(图2)及不规则曲面柱等。由于其截形为不规则非圆形曲线(图3),曲线上的每一点与旋转中心 O 构成的向径 R 也不相等,因此在车制这类轴时,刀子应随非圆形曲线向径的大小作跟踪移动。 First, the non-circular shaft turning hydraulic profiling equipment modification 1 Overview Most of the parts can be processed in the lathe, the shape is based on the lathe spindle axis symmetrical distribution, such as the ladder shaft, special shaft (Figure 1) Wait. The cross section of these parts is a complete circle, but the radius of each cross section is not necessarily the same (with the shape of the shaft changes). The shape of some parts is not symmetrical with the spindle axis of the lathe. The cross section of the part is a noncircular curve such as a camshaft, a polygonal shaft (Figure 2) and an irregular curved surface column. Because of its truncated irregular non-circular curve (Figure 3), each point on the curve and the center of rotation O constitute the radial R is not equal, so in the car-like axis, the knife should be non-circular curve Track the size of the track to move.
