摘　　要：镗床夹具是镗孔加工中常用的辅助装置。针对差速器壳体上两组相互垂直孔的加工,设计了专用的镗孔夹具。鉴于差速器壳体的结构特点和镗孔工序要求,采用一面两孔定位,并确定了满足定位精度要求的定位销尺寸。接着,确定了可靠的工件夹紧方案,并设计了油缸以及相关的夹紧装置。最后介绍了该夹具的结构组成及其特点。The fixture of boring machine is a common used auxiliary device in boring operation. In view of the machining of two groups of holes in differential housing, a special purpose boring fixture is designed. Considering the structure of differential housing and boring operation requirements, one plane and two holes are used to be the location surfaces, and the dimensions of location pins are determined so as to meet the location accuracy. Next, a reliable clamping plan is determined, and the hydraulic cylinder and relevant clamping devices are designed. The components and characteristics of the fixture structure are introduced finally.
