Apparatus and method for a compression spindle assembly for clamping

摘要

A compression spindle for use in a clamp for holding a work piece has a plunger with a bore that defines a seat for a spring. A spindle is inserted into the bore against the spring. A retainer screw holds the spindle in restrained, sliding engagement with the plunger, and allows the spring compression to be adjusted. The spring is completely encapsulated within the compression spindle assembly. When installed in a clamp or press, the compression spindle mediates application of holding pressure on a work piece, and reliably holds work pieces of varying dimensions without adjustment of the clamp.
