Infeed shuttle table for vertical broach

Abstract

A broaching machine has a broach carrying ram mounted for reciprocating movement in a vertical path through a downward cutting stroke and an upward return stroke. A work holding table has a support plate on its upper surface receiving a part holding fixture thereon to hold parts in position for cutting by said tool, and the lower surface of said table has a pivot mounting to the machine base. Horizontal shuttling movement of said plate toward and away from the ram path is provided by a cam block movable transversely in said table and having a cam slot extending at an angle to the path of movement of the cam block. A cam follower is attached to the underside of the table and extending into said cam slot, and pistons are arranged in the table to reciprocate the cam block. The cam slot extends at an acute angle to the path of the cam block. A cylinder and latching linkage is connected for tilting said table between a cutting position with the plate horizontal and normal to the ram path and a loading position with the plate tilted upward and away from the ram path.
