一种特殊塞规的设计

Design of A Special Plug Gauge

某新品零件活塞,内腔型面复杂,孔底部的端面环形槽的大径尺寸大于孔口尺寸,形成孔口小内型腔大的形状结构,常规的检测方法,已不能满足检测要求。本文设计一种特形塞规,用于该零件孔底端面环形槽大径的检测,操作方便、快捷,能够满足中等精度零件的批量检测需求,比较适合批量生产的场合。

A new type of piston has complicated internal cavity surface,with larger large diameter of end ring groove at hole bottom than size of the hole,forming structure of smaller hole and larger internal cavity.Routine detection method can not meet detection requirements.The paper designs a special plug gauge to detect large diameter of ring groove at bottom face of the hole,which is convenient and fast,can meet batch detection requirements of medium precision parts,and is suitable for situation of batch production.
