Patent number: 8698038Abstract: The present invention relates to a system and method for automated or “robotic” application of hardfacing to the surface of a steel-toothed cutter of a rock bit. In particular, the system incorporates a grounded adapter plate and chuck mounted to a robotic arm for grasping and manipulating a rock bit cutter beneath an electrical or photonic energy welding source, such as a plasma arc welding torch manipulated by a positioner. In this configuration, the torch is positioned substantially vertically and oscillated along a horizontal axis as the cutter is manipulated relative along a target path for the distribution of hardfacing. Moving the cutter beneath the torch allows more areas of more teeth to be overlayed, and allows superior placement for operational feedback, such as automatic positioning and parameter correction. In the preferred embodiment, sensors provide data to the control system for identification, positioning, welding program selection, and welding program correction.Type: GrantFiled: September 18, 2009Date of Patent: April 15, 2014Assignee: Baker Hughes IncorporatedInventors: David K.

Patent number: 7861806Abstract: A shank configuration for rotary drill bits is disclosed for positioning of the shank in relation to a bit body. A tapered surface or feature of the shank may be configured and sized to matingly engage a complementarily shaped surface or feature of the drill bit body and thereby become centered or positioned in relation thereto. A deformable element may be disposed between the shank and bit body. Also, the shank may comprise a material having a carbon equivalent of less than about 0.35%. A multi-pass weld procedure may be employed to affix the shank and bit body to one another wherein welds may be formed so that one weld originates at a circumferential position that differs from the origination circumferential position of its immediately preceding weld by at least about 90°. Further, a stress state may be developed within the multi-pass weld.

Publication number: 20100282026Abstract: A method and system for manufacturing a earth boring tool, comprising placing a tool in a positioner of an system which then conforms the tool to a model through the performance of a plurality of processing steps thereon. The positioner may move the tool in two axis. The system may include a manipulator which performs each of the processing steps. Alternatively, the system may include a plurality of manipulators, each performing a different one of the processing steps. The processing steps may include various shaping, cleaning, painting, and packaging steps. The processing steps may be performed without removing the tool from the positioner. The tool may be repositioned in the positioner during or between processing steps. For example, performing the processing steps may comprise performing one or more of the process steps, repositioning the tool in the positioner, and re-performing the one or more of the process steps.Type: ApplicationFiled: May 11, 2009Publication date: November 11, 2010Applicant: BAKER HUGHES INCORPORATEDInventors: David K.
