Abstract
A polishing fixture assembly comprises a fixture base, which has a ferrule aperture and a spring member, and a clamping assembly. The spring member comprises upper, middle, and lower springs. The upper spring forms a portion of a cam aperture. The middle spring is proximate the ferrule aperture. The clamping assembly has a clamp base, a lever, and a cam shaft. The clamp base is connected to the fixture base. The lever is pivotally connected to the clamp base and has unlocked and locked positions. The cam shaft is connected to the lever and rotates within the cam aperture when the lever pivots. As the lever is moved into the locked position, the cam shaft rotates, opposing narrower sides of the cam shaft contact the upper spring thereby flexing the middle spring and the lower spring so that the middle spring contacts a ferrule positioned in the ferrule aperture.
