Abstract

An adjustable magnetic jig 20 includes a first magnetic holder 22, and a second magnetic holder 26. A pivoting joint 30 connects the first 22 and second 26 magnetic holders, so that the angle A between the holders may be selectively adjusted. Pivoting joint 30 is also selectively lockable so that angle A can be fixedly maintained. Jig 20 is particularly useful in holding magnetic workpieces 500 in a desired physical relationship so that the two workpieces 500 can be welded together.

Claims

1. An adjustable magnetic jig, comprising:

a first magnetic holder having a first longitudinal axis;

a second magnetic holder having a second longitudinal axis, said second longitudinal axis coplanar with and intersecting said first longitudinal axis to form an angle therebetween;

a pivoting joint connecting said first and second magnetic holders, so that said angle may be selectively adjusted;

said first and second magnetic holders each further including at least one magnet;

said first and second magnetic holders each further including first and second walls which intersect at a substantially 90°

angle forming first and second substantially perpendicular planar surfaces, the intersection of said surfaces defining said first longitudinal axis for said first magnetic holder, and defining said second longitudinal axis for said second magnetic holder;

said first wall further including a first magnet-receiving cavity, and said second wall further including a second magnet-receiving cavity; and

,

a removable cover covering both said first and second magnet receiving cavities.

3. An adjustable magnetic jig according to claim 1, said pivoting joint further having first and second rotary members, said first rotary member connected to said first magnetic holder, and said second rotary member connected to said second magnetic holder, said first and second rotary members rotatable with respect to each other.

5. An adjustable magnetic jig according to claim 1, further including a magnetic workpiece placed in said first magnetic holder so that the workpiece abuts both said first planar surface and said second planar surface.

6. An adjustable magnetic jig according to claim 1, said first wall further including a first magnet-receiving cavity, and said second wall further including a second magnet-receiving cavity.

7. An adjustable magnetic jig according to claim 1, wherein said pivoting joint is selectively lockable so that said angle can be fixedly maintained.

9. An adjustable magnetic jig according to claim 6, wherein said first and second rotary members can be angularly positioned so that said angle is between substantially 45°

and 180°

.

10. An adjustable magnetic jig according to claim 7, wherein said first rotary member includes one of angular indicia and an index mark, and said second rotary member includes the other of angular indicia and an index mark.

2. An adjustable magnetic jig, comprising:

a first magnetic holder having a first longitudinal axis;

a second magnetic holder having a second longitudinal axis, said second longitudinal axis coplanar with and intersecting said first longitudinal axis to form an angle therebetween;

a pivoting joint connecting said first and second magnetic holders, so that said angle may be selectively adjusted;

said first and second magnetic holders each further including at least one magnet;

said first and second magnetic holders each further including first and second walls which intersect at a substantially 90°

angle forming first and second substantially perpendicular planar surfaces, the intersection of said surfaces defining said first longitudinal axis for said first magnetic holder, and defining said second longitudinal axis for said second magnetic holder; and

,

said first and second magnetic holders being substantially channel-shaped.

4. An adjustable magnetic jig for first and second workpieces, comprising:

a first magnetic holder having a first longitudinal axis;

a second magnetic holder having a second longitudinal axis, said second longitudinal axis coplanar with and intersecting said first longitudinal axis to form an angle therebetween;

a pivoting joint connecting said first and second magnetic holders, so that said angle may be selectively adjusted;

said first and second magnetic holders each further including at least one magnet;

said first and second magnetic holders each further including first and second walls which intersect at a substantially 90°

angle forming first and second substantially perpendicular planar surfaces, the intersection of said surfaces defining said first longitudinal axis for said first magnetic holder, and defining said second longitudinal axis for said second magnetic holder; and

,

the first workpiece abutting said first and second planar surfaces of said first magnetic holder, and the second workpiece abutting said first and second planar surfaces of said second magnetic holder.

8. An adjustable magnetic jig, comprising:

a first magnetic holder having a first longitudinal axis;

a second magnetic holder having a second longitudinal axis, said second longitudinal axis coplanar with and intersecting said first longitudinal axis to form an angle therebetween;

a pivoting joint connecting said first and second magnetic holders, so that said angle may be selectively adjusted;

said first and second magnetic holders each further including at least one magnet;

said first and second magnetic holders each further including first and second walls which intersect at a substantially 90°

angle forming first and second substantially perpendicular planar surfaces, the intersection of said surfaces defining said first longitudinal axis for said first magnetic holder, and defining said second longitudinal axis for said second magnetic holder;

said first wall further including a first magnet receiving cavity, and said second wall further including a second magnet receiving cavity;

a removable cover which covers both said first and second magnet receiving cavities;

said pivoting joint further having first and second rotary members, said first rotary member connected to said first magnetic holder, and said second rotary member connected to said second magnetic holder, said first and second rotary members rotatable with respect to each other;

said first rotary member including angular indicia, and said second rotary member including an index mark; and

,

said pivoting joint selectively lockable so that said angle can be fixedly maintained.
