| 1 | Method for providing a controlled spark plug orientation in an engine structure | US12251950 | 2008-10-15 | US08407891B2 | 2013-04-02 | Daniel K Owusu; David H. Shea |
| A spark plug orientation method may include forming a spark plug housing by advancing a tool a first distance in a first axial direction into a spark plug bore to create a spark plug seat using a seat forming portion of the tool. The tool may be displaced a second distance in a second axial direction generally opposite the first axial direction to provide a predetermined axial orientation between the thread forming portion of the tool and the spark plug seat. The spark plug bore may be engaged at a first predetermined rotational position and the tool may be displaced in an orbital motion and in the second axial direction at a predetermined rate to form a threading on the spark plug bore providing a starting point of the threading at a second predetermined rotational position proximate the spark plug seat. | ||||||

| An inexpensive method for repairing a damaged spark plug hole of a cylinder engine includes drilling the damaged spark plug hole using a drill bit, tapping the drilled spark plug hole, threading a steel insert into the threaded hole and making a spark plug seat. The depth of the drilling, tapping and threading is limited by a stopper. A set of new tools are used to realize the foregoing process. All these procedures can be done while the cylinder having the damaged spark plug hole on the vehicle. The resulting hole is stronger and more durable than the original spark plug hole in the aluminum cylinder head. | ||||||

| A method of producing a rotationally orientated thread starting at a desired angular position and suitable for mass production is provided. The method is particularly suitable for improving the angular positioning of spark plugs in car engines. The method involves measuring precisely the length (L) of the tool (13) and the distance, at a particular angular position, of a full thread form (14) of the thread to the tip, so that its start position at the tip can be calculated. Using that distance as an offset of the length of the tool reported to the CNC machine, and starting from its reference position, it commences producing the thread (12) in the bore (11) at the desired angular position of the bore (11). | ||||||

| The concept of my idea is a tool used in conjunction with a ratchet wrench that would re-thread a hole into which a spark plug was inserted or other holes with in which the threads are cross-threaded. It can be used in engine cylinder heads on both styles of engines, works well with over head cam engines. Produced from tool-grade steel, measuring 5 inches long and vary in diameter (null and null inch.) null-inch diameter found at the top of this tool would allow for the attachment of a null-inch drive shaft of a ratchet wrench. The bottom of the shaft would feature threads that allow internal threads to align correctly. A ratchet wrench would be cranked to create the turning motion needed to cut the threads. This tool provides convenience, durability, and efficiency. The professional auto mechanics and the do-it-yourselfer can use it. | ||||||

| 7 | Threaded insert for tapered seat spark plug bores, installation tools, and method of installation | US10301272 | 2002-11-20 | US06668784B1 | 2003-12-30 | Gary Sellers; Michael L. Shiffermiller |
| A thread insert and method to replace the damaged threads and tapered seat in a spark plug bore of an internal combustion engine allows for the continued use of the original factory specified spark plugs where the original threads in the spark plug bore have been damaged by stripping or cross threading. The thread insert's inner bore is designed to replace the original threads and tapered seat in the cylinder head. The thread insert may be adapted to fit any internal combustion engine using tapered seat spark plugs, and is particularly useful in deep spark plug bores with limited access as found in the aluminum heads in Ford modular engines. The insert includes a flange head that determines how far into the head the insert can extend and a recess below the flange to collect any bonding agent that may be squeezed from the threads during installation of the insert. Special tools make the installation of the insert easy and accurate. | ||||||

| PROBLEM TO BE SOLVED: To provide a tapping method capable of starting processing while making a rotating direction phase of a thread cutting starting position being a starting position of an internal thread section a specific position at all times when tapping by a machine tool.SOLUTION: The tapping is conducted by mounting a preset tapping tool, in which a tap 16 is supported by a tool holder, on a main shaft of the machine tool, moving it to approach a pitch feed starting position for tapping a work, identifying the rotating direction, and applying pitch feed. Prior to tapping, the position of the tap 16 in the rotation direction is determined against the tool holder based on a rake face of a threaded section 17 of the tap 16 in a state that the preset tapping tool is not yet mounted and the length of the tool is preset based on a flank 31 of a peak 17a of a first peak of a complete peak section T1 among the threaded section 17 of the tap 16. | ||||||
