ABSTRACT:
The invention is basically a device that allows an individual to align the broaching tool more accurately. The invention begins with a base plate that is attached to the retriever base or puller head of the broach machine. Within the base plate is a large broach stick opening through which the retriever end or the puller end of the broach tool is placed. Attached to the base plates are four rails around the large openings. The adjustment plate is a plate that fits on top of the base plate and within the area created by the four rails. In the center of the adjustment plate is a large opening for the attachment of the retriever end or puller end of the broach tool. Also the adjustment plate has openings for attachment through bolts to the base plate. In the four rails there are also openings for set screws that pass through the rails and make contact with the adjustment plate fit within the area created by the rails. These set screws allow the retriever plate to be adjusted in all directions perpendicular to the broach. Once the broach tool is fully adjusted the adjustment plate bolts that attach it to the base plate are tighten down to hold that adjustment plate in place. The adjustment plate can be easily readjusted by loosening up the bolts that hold the adjustment plate to the base plate and making the adjustment with the four sets of set screws.
