Apparatus for Coupling Tool Holders
|
James G. Zeilinger |
Frankenmuth, Saginaw County, MI |
Abstract
Apparatus for coupling a tool holder to a machine tool spindle wherein the tool holder is fitted to a coupling interposed between the tool holder and the spindle. The coupling and the tool holder have separable fasteners for separably joining the tool holder and coupling together. The coupling can accommodate tool holders having dissimilar fasteners and the tool holder can be fitted to couplings having dissimilar fasteners. |

High Accuracy Machining Station for a Multiple Spindle Rotary Indexing Machine Tool
|
Jesse W. Mendenhall |
Fairfield, Fairfield County, CT |
Abstract:
The invention relates to improvements in the multiple spindle rotary indexing machine tool systems of the prior art. Traditionally, such machine tool systems include a base and an upstanding vertical column which houses a plurality of machining stations each equipped with two-axis tool slides. In addition, the base supports a rotatable worktable, which carries a number of work-holding spindles. As the worktable rotates, these spindles are indexed through successive machining stations where a variety of operations are performed. In accordance with the invention, a spindle position measurement unit is provided to dynamically measure the exact location of each spindle indexed to position at a modified machining station. A computerized numerical control system calculates spindle position errors based on the position information provided by the measurement unit and offsets tool slide position commands to compensate for those errors. As a result, the control unit compensates for both fixed and variable spindle position variations, thus improving the machining tolerances of the machine tool apparatus. In accordance with another aspect of the invention, a high accuracy finishing station is provided which includes spindle position variation measurement and compensation in combination with an independent X and Y axis tool slide positioning system. The tool slide positioning system is responsive to CNC commands for speed control and position offset due to spindle errors. |

Bar Stock Feeder Method and Apparatus Having Separable Guide Tube Sections
|
Kirt M. Babuder |
Euclid, Cuyahoga County, OH |
Abstract:
A bar stock feeder for feeding bar stock to a multiple spindle lathe is disclosed. The bar stock feeder has several guide tubes, each for holding a piece of stock. The tubes are flooded with hydraulic fluid to provide a film of fluid to support the pieces of stock. Each tube contains a piston for advancing the pieces of stock towards the lathe. The tubes have a pivoting part which allows the operator to separate the tubes for reloading. The pistons are retracted into the pivoting part of the tubes prior to separation such that they are not in the way during reloading. |

Combination Fence and Table for Power Tool
|
Walter M. Bishop |
McMinnville, Warren County, TN |
Abstract:
A combination fence and table for use with a power tool provides means for rotating a plate from a table position to a fence position. The plate also is tiltable with respect to the base of the apparatus. The edge of the plate closest to the power tool remains at a substantially constant distance from the power tool throughout the range of angles that the plate is tilted. When used in the fence position, the plate is movable linearly across the width of the power tool. |

Multiple-Spindle Bar Machine
|
Kirt M. Babuder |
Euclid, Cuyahoga County, OH |
Abstract:
A multiple spindle bar machine is disclosed including a cylindrical spindle carrier assembly supporting a spaced apart array of spindle bearings. Workpiece holding spindles are rotatably journaled in the spindle bearings. A hollow spindle drive shaft extends through a central opening in the spindle carrier and includes a drive gear pinned to an end of the shaft. The drive gear intermeshes with spindle gears to drive the spindles at a uniform rotational speed. The spindle carrier assembly is rotatably supported by at least one set of tapered roller bearings bearing against an outer peripheral surface of a spindle carrier. The set of roller bearings are disposed in a notched annulus in an inner peripheral surface a headstock upright. Each roller bearing forms an acute included angle between the spindle carrier outer peripheral surface and a surface of the tapered bearing facing the spindle carrier. The set of tapered roller bearing is mechanically preloaded before machining operations commence. The spindle carrier includes an interior manifold comprising passageways between the spindle bearings. A connector assembly including a swivel connector is provided to route pressurized fluid in the hollow cavity of the spindle drive shaft to the interior manifold of the spindle carrier to preload the spindle bearings. |
