The invention discloses a clamp for
hydraulic cylinder abrasive flow
machining. The clamp comprises a base, a bottom plate, a convex ball base, a rotating base, a
hydraulic cylinder clamping base, a spiral disc, a rotation rod, an upper fixed base and an upper cover base; when
abrasive flow finish
machining is carried out a
hydraulic cylinder, the hydraulic cylinder can be rapidly clamped, duringclamping, a connecting pin only needs to be detached, the upper fixed base is taken down, an outer lock sleeve of an axial connecting
assembly is drawn out, a first connecting clamping ring and a second connecting clamping ring are separated, the upper cover base and the hydraulic cylinder clamping base are separated, the hydraulic cylinder is fixed into the hydraulic cylinder clamping base, the axial connecting
assembly is mounted, the upper fixed base is positioned, the connecting pin is connected,
abrasive flow media are led in, the rotating rod and the rotating base are started, and rotatein the opposite directions, the abrasive flow media can achieve
impact machining on the surface of the hydraulic cylinder under rotation of the spiral disc, machining efficiency is high, and the finish machining of the surface of the hydraulic cylinder can be comprehensively achieved.
