Fixture structure for machining rear suspension left and right supports of engine

The utility model discloses a clamp structure for machining a left support and a right support of a rear suspension of an engine, which comprises a clamp body for clamping and positioning the left support and the right support of the rear suspension of the engine and a rotating body for driving the clamp body to rotate. The clamp chassis is provided with a clamp L-shaped positioning block used for limiting the axial freedom degree of the engine rear suspension left and right supports, a clamp pressing device used for limiting the rotation freedom degree of the engine rear suspension left and right supports and a clamp self-adaptive supporting block used for preventing the engine rear suspension left and right supports from vibrating. The device is suitable for the vertical machining center, and is simple in structure and good in stability. 本实用新型公开了一种用于发动机后悬置左右支架加工的夹具结构，其包括用于夹持定位发动机后悬置左右支架的夹具体和用于驱动夹具体旋转的旋转体，所述夹具体包括用于连接所述旋转体的夹具底盘，所述夹具底盘上设置有用于限制发动机后悬置左右支架的轴向自由度的夹具L形定位块、用于限制发动机后悬置左右支架的回转自由度的夹具压紧装置和用于防止发动机后悬置左右支架震
