Abstract:
1. A bevel cut depth controller in a beveling machine comprising: a beveling machine body having a movable spline shaft vertically movably connected to the spline shaft connection unit by a screw and including a first spline positioned around an upper outer circumference of the movable spline shaft; a bevel cut depth controlling unit including a second spline surrounding an outer periphery of the movable spline shaft, the second spline being positioned around an inner circumference of the bevel cut depth controlling unit, movable in a vertical sliding motion and connected to the first spline; a spring housing inserted into a guide groove formed at an upper part of the bevel cut depth controlling unit and integrally attached to an upper end of the movable spline shaft; an elastic spring interposed between an inner surface of the spring housing and the guide groove of the bevel cut depth controlling unit; a plurality of securing openings formed along a lower part of the bevel cut depth controlling unit; a plurality of location setting pins positioned along an upper outer part of the spline shaft connection unit and selectively fit into the securing openings, to fix the location of the bevel cut depth controlling unit and maintain the locking thereof, each of said plurality of location setting pins including a screw part, the screw part being connected/separated to/from a screw hole formed on an upper outer part of the spline shaft connection unit; a sleeve shaft rotatably installed in the movable spline shaft; a bearing housing installed in the cutter operation unit; and a cutter shaft rotatably installed in the bearing housing, wherein the cutter shaft is integrally connected to a lower end of the sleeve shaft so that the cutter shaft and the sleeve shaft operatively rotate and vertically move together.
