Abstract
The invention discloses a gear reversing and shifting cantilever clamp combination. The gear reversing and shifting cantilever clamp combination comprises a bottom plate, a positioning base, a positioning base supporting block and two rapid clamping assemblies sequentially arranged side by side from left to right in a spaced manner. Two positioning shafts on workpiece positioning blocks are inserted in corresponding installation holes in workpieces respectively. A hard alloy block is welded to each inclined face of a V-shaped opening in each V-shaped positioning block. The workpieces are pressed by the hard alloy blocks from the left side and the right side of the rear portions of the workpieces. Semicircular notches are formed in the ends of pressing plates. Oil hydraulic swing clamp cylinders drive the pressing plates to rotate so that the ends of the pressing plates can be pressed on the upper end faces of the rear right portions of the workpieces. Locking threaded rods horizontally and obliquely penetrate locking fixing blocks to abut against the left front walls of the workpieces. The execution ends of lever type hydraulic oil cylinders abut against the center positions of the front portions of the workpieces. The cantilever ends of the workpieces are clamped through the locking fixing blocks and elastic ejecting mechanisms. The workpieces can be rapidly and accurately clamped and positioned when the gear reversing and shifting cantilever clamp combination is applied to a vertical machining center; and the number of clamps and the number of clamping times are decreased, the work efficiency is improved, and the labor cost is reduced.
