Abstract
In a device for indexing a work attached to a cutting device of a machine center, the device for indexing comprises an indexing plate connected to a driving shaft of an indexing table and held by a stopper on the normal position on a base, a push bar interlocking operatively with an extra action other than the normal action of a tool to move linearly relative to the base, an actuating member for rotating the indexing plate by engaging the push bar operatively. The device is so constructed to disengage a stoppage of the indexing plate by the stopper and rotate the indexing at fixed angles with the aid of the actuating member when indexing a work.
Claims1
An NC milling machine for indexing a work comprising an indexing plate connected to an actuating axis of an indexing table holding a work in position by a crank member having an engaged groove at a tip thereof and a crank pin, a push bar for moving linearly relative to a base of the device, and an actuating means for engaging in the push bar and rotating the indexing plate at fixed angles, said actuating means including a rotating plate mounted rotatably to the actuating axis relative to said indexing plate, an engaged portion provided in said rotating plate and engaging said push bar and a claw member attached to said rotating plate and engaged in an engaging claw, said crank pin engaged in a central portion of said engaging claw, said NC milling machine being so constructed to index the work such that the actuating means rotates the indexing plate at fixed angles in accordance with a linear action of the push bar, the push bar being interlocked with an extra action other than the normal action of a tool of a cutting device of a machining center.
