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.

Claims

1. An adjustable mechanism for aligning a broach tool for a broach machine comprising:

a. a plate; and

,

b. a first attachment means for attaching the plate to the broach machine; and

,

c. a second attachment means for attaching the plate to the broach tool such that when the plate is moved for adjustment the broach tool moves for adjustment; and

,

d. rails attached to the broach machine around the plate; and

,

e. a protrusion means that protrudes from the rails and that makes contact with the plate and can move the plate in a plane perpendicular to the center line of the broach tool.

2. An adjustable mechanism for aligning a broach tool for a broach machine as in claim 1 wherein:

a. the second attachment means for attaching the plate to the broach tool allows the plate to move for adjustment.

3. An adjustable mechanism for aligning a broach tool for a broach machine as in claim 2 wherein:

a. the first attachment means for attaching the plate to the broach machine comprises;

(1) a set of openings in the plate; and

,

(2) screws adapted to pass through said openings, said body of the screws being smaller than the openings and said head of the screws being larger than the openings; and

,

(3) a threaded means for attaching the screws to the broach machine; and

,

(4) whereby when the plate is to be adjusted the screws are loosened and the plate is adjusted in the desired direction and then the screws are tightened to hold the plate in that position.

4. An adjustable mechanism for aligning a broach tool for a broach machine as in claim 3 wherein:

a. the threaded means for attaching the screws to the broach machine is a base plate with threaded openings that the screws are adapted to thread within and said base plate is securely attached to the broach machine.

5. An adjustable mechanism for aligning a broach tool for a broach machine as in claim 4 wherein:

a. the protrusion means for protruding from the rails comprises;

(1) threaded openings in the rails; and

,

(2) screws that are adapted to fit within the threaded openings in the rails, said screws being of sufficient length that they make contact with the plate; and

,

(3) whereby the screws maybe threaded in or out of the openings in the rails and said screws makes contact with the plate and moves the plate in the desire direction of adjustment.

6. An adjustable mechanism for aligning a broach tool for a broach machine as in claim 3 wherein:

a. the protrusion means for protruding from the rails comprises;

(1) threaded openings in the rails; and

,

(2) screws that are adapted to fit within the threaded openings in the rails, said screws being of sufficient length that they make contact with the plate; and

,

(3) whereby the screws may be threaded in or out of the openings in the rails and said screws make contact with the plate and move the plate in the desired direction of adjustment.

7. An adjustable mechanism for aligning a broach tool for a broach machine as in claim 2 wherein:

a. the first attachment means for attaching the plate to the broach machine comprises;

(1) a set of openings in the plate that are elliptical; and

,

(2) washers which are circular and whose openings are elliptical; and

,

(3) screws adapted to pass through said washers and said openings whose body is smaller than the openings of the washer and openings and whose head is larger than the openings in the washer; and

,

(4) a threaded means for attaching the screws to the broach machine; and

,

(5) whereby when the plate is to be adjusted the screws are loosened and the plate is adjusted in the desired direction and then the screws are tightened to hold the plate in position.

8. An adjustable mechanism for aligning a broach tool for a broach machine as in claim 7 wherein:

a. the threaded means for attaching the screws to the broach machine is a base plate with threaded openings that the screws are adapted to thread within and said base plate is attached securely to the broach machine.

9. An adjustable mechanism for aligning a broach tool for a broach machine as in claim 7 wherein:

a. the protrusion means for protruding from the rails comprises;

(1) threaded openings in the rails; and

,

(2) screws that are adapted to fit within the threaded openings in the rails, said screws being of sufficient length that they make contact with the plate; and

,

(3) whereby the screws may be threaded in or out of the openings in the rails and said screws make contact with the plate and move the plate in the desired direction of adjustment.

10. An adjustable mechanism for aligning a broach tool for a broach machine as in claim 1 wherein:

a. the protrusion means for protruding from the rails comprises;

(1) threaded openings in the rails; and

,

(2) screws that are adapted to fit within the threaded openings in the rails, said screws being of sufficient length that they make contact with the plate; and

,

(3) whereby the screws may be threaded in or out of the openings in the rails and said screws make contact with the plate and move the plate in the desired direction of adjustment.

11. An adjustable mechanism for aligning a broach tool for a broach machine as in claim 10 wherein:

a. the plate is square.

12. An adjustable mechanism for aligning a broach tool for a broach machine as in claim 11 wherein:
