T形接头利用V形支承定位时,在工艺上常常是将T形接头装夹在图1所示的V形支承上进行加工的。图1中用粗实线来表示T形接头在夹具中的理论位置,用细实线来表示T形接头在夹具中的实际位置。此外,夹紧T形接头时,迫使T形接头下垂并移动ε/2的距离,工件与V形支承的工作平面在A点与B点相接触。在图1中是用虚线来表示其移动(0点移

T-shaped connector using V-shaped support positioning, the process is often T-shaped connector shown in Figure 1 mounted on the V-shaped bearing for processing. The thick solid line in Figure 1 shows the theoretical position of the T-joint in the clamp, and the thin solid line shows the actual position of the T-joint in the clamp. In addition, when clamping the T-joint, the T-joint is forced to droop and move by a distance of ε / 2. The working plane of the workpiece and the V-shaped support are brought into contact with point A at point A. In Figure 1 is the dotted line to indicate its movement (0 point shift
