Abstract

A universal squaring jig which may be used when welding various workpieces in perpendicular orientation. The squaring jig has two workpiece holders attached together by one or more support members. Each holder has three mating surfaces. The first and second mating surfaces together form a perpendicular interior corner. The first and third mating surfaces form a perpendicular exterior corner. Magnets are placed on both the first and third mating surfaces to hold workpieces in mating contact with the surfaces of the squaring jig during welding.

Claims

1. A multifunctional squaring jig for holding a first workpiece and a second workpiece in abutment, comprising:

a. a first holder having a first mating surface, a second mating surface, and a third mating surface, said first mating surface and said second mating surface foiling a first interior corner;

b. a second holder attached to said first holder, said second holder having a fourth mating surface, a fifth mating surface, and a sixth mating surface, said fourth mating surface and said fifth mating surface forming a second interior corner;

c. wherein said first mating surface and said fourth mating surface are coplanar on a main plane, said second mating surface is situated on a first vertical plane perpendicular to said main plane, said third mating surface is situated on a second vertical plane perpendicular to said main plane and parallel to said first vertical plain, said fifth mating surface is situated on a first horizontal plane perpendicular to both said main plane and said first vertical plane, and said sixth mating surface is situated on a second horizontal plane perpendicular to both said main plane and said first horizontal plane and parallel to said first horizontal plane;

d. wherein said squaring jig is configured to hold and maintain said first workpiece and said second workpiece in a perpendicularly-abutted orientation in both a first aligning configuration and a second aligning configuration;

wherein in said first aligning configuration, said first workpiece mates with said first mating surface and said second mating surface and said second workpiece mates with said fourth mating surface and said fifth mating surface; and

wherein in said second aligning configuration, said first workpiece mates with said third mating surface and said second workpiece mates with said sixth mating surface.

2. The multifunctional squaring jig of claim 1, wherein said first mating surface and said third mating surface together form a first exterior corner and said fourth mating surface and said sixth mating surface together form a second exterior corner.

3. The multifunctional squaring jig of claim 1, wherein said first mating surface extends between said second mating surface and said third mating surface and said fourth mating surface extends between said fifth mating surface and said sixth mating surface.

4. The multifunctional squaring jig of claim 2, wherein said first mating surface extends between said second mating surface and said third mating surface and said fourth mating surface extends between said fifth mating surface and said sixth mating surface.

5. The multifunctional squaring jig of claim 1, further comprising a first-magnet attached to said first holder, said first magnet configured to exert an attractive force such that said first workpiece in held in mating contact with said third mating surface.

6. The multifunctional squaring jig of claim 1, further comprising a first magnet attached to said third mating surface and a second magnet attached to said sixth mating surface.

7. The multifunctional squaring jig of claim 1, wherein said holder is configured to exert a magnetically attractive force on said first workpiece when said first workpiece is placed against said third mating surface.

8. The multifunctional squaring jig of claim 1, said third mating surface having a first edge and a second edge, said first edge adjacent to said first mating surface and said second edge extending outward away from said first mating surface.

9. The multifunctional squaring jig of claim 8, further comprising a first magnet attached to said third mating surface between said first edge and said second edge.

10. The multifunctional squaring jig of claim 8, said sixth mating surface having a third edge and a fourth edge, said third edge adjacent to said fourth mating surface and fourth second edge extending outward away from said fourth mating surface.

11. The multifunctional squaring jig of claim 9, further comprising a second magnet attached to said first mating surface between said first edge of said third mating surface and said first interior corner.

12. A multifunctional squaring jig for holding a first workpiece and a second workpiece in abutment, comprising:

a. a first holder having a first mating surface, a second mating surface, and a third mating surface, said first mating surface and said second mating surface forming a first interior corner, said first mating surface and said third mating surface forming a first exterior corner, said third mating surface having a first edge extending away from said first mating surface;

b. a second holder attached to said first holder, said second holder having a fourth mating surface, a fifth mating surface, and a sixth eating surface, said fourth mating surface and said fifth mating surface forming a second interior corner, said fourth mating surface and said sixth mating surface forming a second exterior corner, said sixth mating surface having a first edge extending away from said fourth mating surface;

c. wherein said first mating surface and said fourth mating surface are coplanar on a main plane, said second mating surface is situated on a first vertical plane perpendicular to said main plane, said third mating surface is situated on a second vertical plane perpendicular to said main plane and parallel to said first vertical plain, said fifth mating surface is situated on a first angular plane perpendicular to said main plane, and said sixth mating surface is situated on a second angular plane perpendicular to said main plane and parallel to said first horizontal plane;

d. wherein said squaring jig is configured to hold and maintain said first workpiece and said second workpiece in an angularly-abutted orientation in both a first aligning configuration and a second aligning configuration;

wherein in said first aligning configuration, said first workpiece mates with said first mating surface and said second mating surface and said second workpiece mates with said fourth mating surface and said fifth mating surface; and

wherein in said second aligning configuration, said first workpiece mates with said third mating surface and said second workpiece mates with said sixth mating surface.

13. The multifunctional squaring jig of claim 12, wherein said first mating surface extends between said second mating surface and said third mating surface and said fourth mating surface extends between said fifth mating surface and said sixth mating surface.

14. The multifunctional squaring jig of claim 12, further comprising a first magnet attached to said first holder, said first magnet configured to exert an attractive force such that said first workpiece in held in mating contact with said third mating surface.
