机器的原理及加工范围 三工位的回转式组合机床是用于精加工小轿车的活塞销孔及外廓椭圆部分的。机床(图1)的节拍为41秒,每小时约加工175个工件(每个节拍加工两件)。工件如图2所示。工作图A—B剖面的鼓形尺寸是以半径37.5毫米为基准的。俯视图上所标的不圆度为数学精确
The principle of the machine and the scope of processing Three-station rotary combination machine is used for finishing the piston pin hole and the outer ellipse part of the car. The machine tool (Figure 1) has a beat of 41 seconds and approximately 175 workpieces per hour (two per beat). Workpiece shown in Figure 2. Drum dimensions in the cross section A-B are based on a radius of 37.5 mm. Top view of the marked roundness is mathematical accuracy
