摘要
分析了连杆小头斜端面上的椭圆孔倒角加工存在的问题,介绍了砂带倒角加工方法及椭圆孔砂带倒角机床的结构与工作原理;在砂带倒角机床上,利用砂带的挠性和卷曲变形,替代加工中刀具或工件沿椭圆的长轴移动的附加运动,工件端面上椭圆孔的棱边在砂带的压力与运动作用下被砂带上的磨料切除,形成倒角平面,实现了椭圆孔的倒角加工。
The chamfer of oval hole on oblique surface of small end of link method presented problems are analyzed, the structure and working principle of oval holes abrasive belt chamfering machine tool are introduced, on the abrasive belt chamfering machine tool, using of the flexible deformation and curling deformation of abrasive belt method substitute that additional movement of cut- ting tool or the workpiece along the long axis of oval hole, the edge of oval hole be removed by grinding material on abrasive belt under the influence of movement and pressure, obtain a chamfer plane, achieve chamfer machining of oval hole.
