Abstract

A mounting fixture for a reconfigurable assembly machine having a plurality of modules with slots formed in their upper surfaces includes a square or rectangular solid block having a plurality of threaded openings. The openings receive fasteners adapted to secure various and diverse assembly machine components and devices to the mounting fixture. One surface of the block includes a channel or keyway having a width equal to the width of the throat of the slots formed in the upper surface of the assembly machine module. A locating key is received in the keyway in the block and the throat of the T-slot. The locating key includes through openings which receive threaded fasteners having heads held captive and the T-slot which, with suitable nuts, secure the block to the upper surface of the module.

Claims

1. A mounting fixture for an assembly machine module comprising, in combination,

at least one mounting block including parallel upper and lower surfaces, defining a keyway, at least one threaded opening and at least one through passageway aligned with said keyway,

a key having at least one through opening, and

a threaded fastener extending through said one through opening in said key and said at least one through passageway in said mounting block and a head capable of inhibiting rotation of said threaded fastener.

2. The mounting fixture of claim 1 wherein said threaded fastener includes a square head.

3. The mounting fixture of claim 1 further including an assembly machine module having a slot defined by opposed, overhanging flanges.

4. The mounting fixture of claim 3 wherein said threaded fastener includes a head configured to slide but not rotate in said slot.

5. The mounting fixture of claim 1 wherein said at least one mounting block includes at least six threaded openings.

6. The mounting fixture of claim 1 wherein said mounting fixture includes at least two mounting blocks utilized in pairs to mount an assembly or testing device.

7. The mounting fixture of claim 1, wherein said parallel upper and lower surfaces are flat.

8. The mounting fixture of claim 1, wherein said key is separable from said mounting block.

9. The mounting fixture of claim 1, wherein at least one through passageway in said mounting block includes a countebore adapted to receive a nut.

10. A mounting fixture for an assembly machine module having a slot defined by opposed, overhanging flanges comprising, in combination,

a mounting block having parallel upper and lower surfaces, defining a projecting key, at least one threaded opening and at least one through passageway in said key, and

a threaded fastener extending through said one through passageway in said key and a head that inhibits rotation of said threaded fastener when disposed in the slot of the assembly machine module.

11. The mounting fixture of claim 10 wherein said threaded fastener includes a square head.

12. The mounting fixture of claim 10 wherein said mounting block includes at least six threaded openings.

13. The mounting fixture of claim 10 wherein said mounting block is utilized in pairs to mount an assembly or testing device.

14. The mounting fixture of claim 10 wherein said key is integrally formed with said mounting block.

15. The mounting fixture of claim 10 wherein said key and said mounting block are separable components.

16. A mounting fixture for an assembly machine module comprising, in combination,

a mounting block having first and second parallel, planar surfaces, a keyway adjacent said first planar surface, at least one through opening extending from said keyway to said second surface, at least one threaded passageway extending from said second surface toward said first surface,

a key extending from said keyway and including a through passageway aligned with said at least one through opening, and

a fastener extending through said through passageway and said at least one through opening and including a head portion defining a shape engageable by a machine element having a surface complementary to at least a portion of said shape.

17. The mounting fixture of claim 16 further including a frame having a surface, a slot in said surface adapted to receive said key and an enlarged region adjacent said slot adapted to receive said head portion and inhibit rotation thereof.

18. The mounting fixture of claim 16 wherein said shape of said head portion is square.

19. The mounting fixture of claim 16 wherein said mounting block includes at least six threaded passageways.

20. The mounting fixture of claim 16 wherein said mounting block is utilized in pairs to mount an assembly or testing device.
