Abstract
A boring bar feed mechanism comprising a boring bar and a rotation mechanism for rotating the boring bar, a feed shaft, a feed coupling the feed shaft with the boring bar for axially translating the boring bar, and the boring bar is rotationally mounted with respect to but axially fixed to a second end of the feed coupler. A cam is rotationally fixed to the boring bar for rotating with the boring bar and a cam follower interacts with the cam. A plunger housing is supported by an extension of the cam follower and the plunger housing accommodates at least one feed plunger. A converter gear is supported by the feed shaft and the feed plunger interacts with the converter gear to facilitate indexing of the converter gear. The plunger housing is pivotally supported by the extension of the cam follower to permit the plunger housing and the feed plunger to have a limited pivoted motion, relative to the cam follower, as the cam follower oscillates back and forth and indexes the feed shaft.
