APPARATUS FOR WORKING GROOVES ON LONG SHAFT

摘要

PURPOSE: An apparatus for working grooves on long shaft is provided to work grooves inside and outside of the long shaft. More specifically, the apparatus is provided to independently work indent grooves on a shaft having various lengths and diameters by solving the limitations owing to the length and inner diameter dimension of a work piece. CONSTITUTION: An apparatus for working grooves on long shaft comprises a ram(10) passing through and traversing a milling machine, of which one side is provided with a bite(12); a ram support frame(20) for fixing the opposite ends of the ram(10) to be capable of moving upward and downward; a movable base(40) being capable of moving frontward and rearward on a horizontal base of a milling machine being movable leftward and rightward; a plurality of clamps(60) for clamping a work piece to the movable base(40); and a ram support(70) for supporting downward deflection of the ram(10) at the opposite sides of the movable base(40), wherein indent grooves are formed while the work piece moves leftward and rightward along a bite of the ram(10). Accordingly, dimensional limitations of the work piece owing to the length and inner diameter dimension of a work piece is solved by fixing a ram with a bite mounted and moving the work piece mounted on the movable base along the ram frontward and rearward.
