三座标测量机可以归纳为悬臂式、桥式、龙门式、卧镗式和座标镗式等5种布局型式。其中,悬臂式有 Z 轴移动和 Y 轴移动的区别,龙门式有龙门移动和龙门固定之分;桥式另外有一种变型——悬臂桥式。因此,三座标测量机共有8种布局型式(图2—1)。由座标镗床发展过来的万能测量机,单柱属于座标镗式,双柱属于龙门固定式。 Three coordinate measuring machine can be summarized as cantilever, bridge, gantry, horizontal boring and coordinate boring and other 5 kinds of layout type. Among them, the cantilever movement of the Z axis and the difference between the Y axis movement, the gantry gantry moves and gantry fixed points; bridge another variant - cantilever bridge. Therefore, the three coordinate measuring machine has a total of eight kinds of layout (Figure 2-1). Developed by the coordinate boring machine universal measuring machine, single column is the coordinates of boring, double column are gantry stationary.
