Abstract
A Tap Driver Assembly for use between a spindle that is adapted to provide a coolant and a tap that is adapted to conduct such coolant therethrough, the tap driver assembly including a body in which a nose is slidably guided, a collet clamped by a nut in such nose, a slidable drive connection between the body and the nose which enables relative axial movement while providing an angular drive, spring means acting between the nose and the body so that the feed of the tap could lead or lag the feed of the spindle, and a fluid passage in the body leading from the spindle in bypassing relation to the slidable drive connection, bypassing the spring means, and extending through the nose, axially into the collet to the tap.
Claims8
A tap driver assembly for a tap adapted to conduct coolant therethrough, comprising in combination:
- (a) a body having means at one end for securing it to a spindle adapted to provide coolant;
- (b) a nose slidably carried in said body;
- (c) a collet in said nose having a driving connection therewith and co-rotatably receptive of a tap;
- (d) a nut carried on said nose for clamping said collet;
- an
- (e) axially slidable angular drive connection between said body and said nose;
- (f) spring means acting axially between said nose and said body;
- and
- (g) a fluid passage extending in said body from said securing means, in radially outward bypassing relation to said slidable drive connection, and said spring means, and extending through said nose and axially into said collet.
