ABSTRACT:
This invention relates to an automatic precision apparatus which includes an elongated rotatable central shaft concentric with and encased by a fixed outer cylinder. A rotary workpiece table is fixed to the central shaft adjacent one end of the central shaft, and a round tool holder table is fixed to the cylinder adjacent one end of the cylinder and disposed in spaced relationship with the rotary table and in parallel arrangement with the rotary table. A plurality of spaced tool holders are disposed around the round table, and a plurality of equally spaced workpiece holders are disposed on one surface of the rotary table facing the round table. Each tool holder is precisely aligned with a respective one of the workpiece holders and is alignable with every other one of the workpiece holders. In one embodiment of the invention, a piston and cylinder arrangement is provided for moving the shaft to a second position relative to the cylinder from a first position relative to the cylinder, and from the second position back to the first position, and a further piston and cylinder arrangement is provided for rotating the shaft relative to the cylinder when the shaft is in the first position relative to the cylinder. An indexing arrangement, consisting of two parallel plates with facing surfaces having a plurality of indentation groups spaced therearound, pairs of indentation groups being aligned with each other, and insert means between the indentation groups is provided for releasably attaching the shaft to the cylinder when the shaft is in the second position relative to the cylinder. Thus, when the shaft is in the first position, the rotary table is rotatable, with the shaft, relative to the round table, which is fixed to the cylinder, to move each workpiece holder from their positions adjacent one of the tool holders to a new position adjacent another one of the tool holders. Further, when the shaft is in the second position, a closed vibration path is provided from each workpiece, through its respective workpiece holder, through the arrangement for releasably attaching, through the cylinder, through a respective tool holder adjacent each workpiece holder, through the tool in the respective tool holder and back to the workpiece.
