Abstract
Methods and systems for concentric clamping for manufacturing assemblies are disclosed. In one embodiment, a drilling assembly includes a spindle assembly configured to perform a drilling operation at a drilling location on a workpiece, and a clamping assembly having an actuator concentrically disposed about the spindle assembly. A nosepiece is coupled to the actuator and is configured to apply a clamping force concentrically about the drilling location on the workpiece. The actuator may include an inner housing having an outwardly extending flange, and an outer housing disposed about the flange of the inner housing. Pressurization of a first chamber moves the inner housing forwardly and applies the clamping force of the nosepiece against the workpiece, and pressurization of a second chamber moves the inner housing aftwardly and retracts the nosepiece away from the workpiece.
