A transfer ring tool for a four-axis machining center

Abstract

The utility model belongs to the technical field of precision machining fixture, disclose a kind of adapter ring tool of four-axis machining center, the tool is aimed at the problem of inaccurate positioning, big cutting vibration, poor surface roughness in traditional clamping of thin-walled adapter ring, and it is proposed to profile double-layer positioning solution;It is mainly composed of annular bottom plate and support plate: the bottom plate is evenly distributed four screw through holes and a pair of positioning pin holes, and three positioning holes are arranged on the outer ring;Support plate is connected with bottom plate by positioning pin hole alignment, and the inner side of annular support boss is provided with a limiting boss, and six boss ears with boss ear screw holes are evenly distributed on the periphery;Workpiece positioning pin hole is arranged on the surface of support boss;When clamping, adapter ring is positioned radially by positioning pin hole, and the lower end is axially limited by limiting boss, six ring ears are locked by bolt and boss ear, and adapter ring wall is reinforced by part fixing screw hole; The tool is profiled by supporting + multi-point locking, eliminates the machining vibration of thin-walled part, realizes the surface finish, and can improve the accuracy of adapter ring clamping.
