ABSTRACT:
A rotary indexing table having a generally circular top plate rotatably secured to a fixed base structure is disclosed. An outer race annular ring is connected to the top of the fixed base structure and extends radially over a central bore formed in the top face of the fixed based structure. A first ring of teeth is formed on the circular top plate. A second ring of teeth is formed on the outer race annular ring. Both the first and second rings of teeth face toward the central bore in the fixed base structure. A piston is slidably mounted in the central bore. The piston has a third ring of teeth aligned with the first ring of teeth and a fourth ring of teeth aligned with the second ring of teeth. A method of forming the third and fourth rings of teeth on the piston is also disclosed. The method includes mounting a sine block on a work table. Then fastening a rotary indexing table on the top of the sine block. Next, securing the piston to the top of the rotary indexing table. Then, setting a first predetermined angle on the sine block to fix a first coning angle from the central axis of the piston. This is followed by cutting one ring of concentric teeth on the piston. Then, adjusting the sine block to a second predetermined angle to fix a second coning angle from the central axis of the piston. Finally, cutting the other ring of concentric teeth on the piston.
