An improved support mechanism for supporting a boring bar at spaced locations along its length within a workpiece during a boring operation, the present support mechanism being particularly adaptable for precision in-line boring of the cam shaft bores associated with overhead cam cylinder heads such as the Ford Escort overhead cylinder head presently in use and being specifically directed to centrally supporting the boring bar intermediate the respective opposite end portions of the cylinder head or other workpiece, the present support mechanism including a first annular member slidably positionable on the boring bar at an intermediate location along its length, the annular member being constructed to enable the boring bar to rotate freely therein, a second member slidably positionable within any one of the lifter bores associated with the particular cylinder head or other workpiece to be re-bored, the second member including a locking mechanism for locking the second member within any one of the lifter bores, and a mechanism for attaching the first annular member to the second member when the boring bar is positioned within the in-line cam shaft bores.
Means for supporting a boring bar within a workpiece during a boring operation wherein the workpiece includes spaced aligned bores at least one of which bores is to be re-bored, the workpiece further including at least one passageway extending radially therein relative to the axis of the aligned bores, said radial passageway being spaced axially from the bore to be re-bored, means for supporting the boring bar at least two locations along the length thereof including a member positionable on the boring bar and constructed to enable the boring bar to rotate freely therein, a locking assembly positionable within said radial passageway including means for attaching the locking assembly to said member positionable on the boring bar, and means to lock the locking assembly in said radial passageway.
Means for supporting a boring bar within a workpiece during a boring operation wherein said workpiece includes spaced aligned bores to be re-bored and at least one passageway extending radially relative to the axis of said aligned bores, said support means including means for supporting the boring bar at spaced locations along the length of said boring bar including a first member positionable on said boring bar at an intermediate location along its length, said first member being constructed so as to enable said boring bar to freely rotate when said first member is positioned thereon, a second member slidably positionable within said radial passageway, means for holding said second member within said radial passageway, and means for attaching said second member to said first member when the boring bar is positioned extending through said aligned bores.
Support means for supporting a boring bar within a workpiece during a boring operation, said workpiece having a plurality of in-line bores and a plurality of passageways, each of said passageways having a longitudinal axis extending radially relative to the longitudinal axis of said in-line bores, said support means including means for supporting the boring bar adjacent the respective opposite end portions of said workpiece and at an intermediate location therebetween, said intermediate support means comprising a first member removably attachable to said boring bar and positionable at an intermediate location along its length, said first member including means enabling said boring bar to move relative thereto, a second member engageable with any one of said plurality of radial passageways, said second member including means for securing said second member within any one of said radial passageways, and means for attaching said first member to said second member when said boring bar is positioned within said plurality of in-line bores.
In a boring machine for boring a plurality of spaced aligned bores in a workpiece, said boring machine including a boring bar extending through said plurality of aligned bores, said workpiece having at least one passageway disposed radially to the axis of said plurality of aligned bores, the improvement comprising support means for supporting said boring bar within said plurality of aligned bores at spaced locations therealong including a first annular member slidably positionable on said boring bar, said first member being positionable beneath any one of said radial passageways when said boring bar extends through said plurality of aligned bores and being constructed to enable said boring bar to freely rotate therein, a second member positionable within one of said radial passageways and including means for maintaining said second member within said radial passageway, and means for attaching said second member to said first member when said first member is positioned beneath the radial passageway into which said second member has been located.
