Clamping table
Apparatus and methods thereof used to clamp and secure workpieces of varying shapes and dimensions into position for welding, machining, and other fabrication activities. A plurality of opposing clamping assemblies attached to the clamping table operate to move and orient separate workpieces into a desired assembly position. The oriented workpieces are then clamped and held in a fixed position for welding, machining, or other fabrication activities.
1 . A clamping table apparatus, comprising:
a base frame comprising at least two frame plates, at least two top rails, at least two bottom rails, at least two clevis plates, and at least one rod, wherein the frame plates are coupled to the top rails and the bottom rails, the clevis plates are attached to the top rails, and the rod is secured at opposing ends to a frame plate of the at least two frame plates;
a clamping assembly comprising a clamp plate, a slider plate, a wedge slide, a jaw, a jaw actuator, a piston, a cylinder saddle, and a tube slider, wherein the clamping assembly is movably coupled to the rod; and,
a table actuator attached to the clamping assembly and secured to the base frame for enabling bi-directional movement of the clamping assembly along the rod.
2 . The apparatus of claim 1 further comprising:
a conveyor frame attached to the base frame, the conveyor frame comprising at least two conveyor rails, at least two conveyor mount channels, at least two conveyor uprights, at least two support rails, and at least one roller attached to the conveyor upright; and,
a conveyor cylinder operable to raise or lower the conveyor frame.
3 . The apparatus of claim 1 further comprising:
a roller attached to a distal end of the jaw.
4 . The apparatus of claim 1 further comprising:
at least two opposing clamping assemblies movably coupled to the rod.
5 . A clamping table apparatus, comprising:
a base frame comprising at least two frame plates, at least two top rails, at least two bottom rails, at least two clevis plates, and at least one rod, wherein the frame plates are coupled to the top rails and the bottom rails, the clevis plates are attached to the top rails, and the rod is secured at opposing ends to a frame plate of the at least two frame plates;
at least two opposing clamping assemblies movably coupled to the rod, wherein the clamping assemblies include a wedge slide with an arcuate surface; and,
a table actuator attached to each clamping assembly movably coupled to the rod for enabling bi-directional movement of each clamping assembly along the rod.
6 . A method for configuring a beam workpiece for a work task, comprising:
providing a configurable clamping table having a plurality of opposing clamping assemblies movably attached to the clamping table;
fixing a first workpiece into a recess in a clamp plate of a first clamping assembly attached to the clamping table;
fixing a second workpiece into a recess in a clamp plate of a second clamping assembly attached to the clamping table opposing the first clamping assembly attached to the clamping table;
placing a third workpiece on a top surface of at least two opposing wedge slides of the first and second clamping assemblies;
actuating the clamping table to move the opposing first and second clamping assemblies toward each other to orient and press the first, second, and third workpieces into contact with each other to form a beam workpiece; and,
clamping the beam workpiece with the plurality of clamping assemblies.
7 . The method of claim 6 further comprising:
providing a conveyor frame for conveying a workpiece along the clamping table.
8 . The method of claim 6 wherein said first workpiece is a beam flange, said second workpiece is a beam flange, and said third workpiece is a beam web.
9 . The method of claim 6 wherein said work task comprises welding.
10 . The method of claim 6 wherein said work task comprises machining.
