A surgical tool for removing a portion of an implant is provided that includes a housing, a motor contained within the housing and coupled to the housing, and an output shaft having a distal end and a proximal end opposite the distal end, wherein the proximal end is coupled to the motor and the distal end has an opening configured to rotateably engage an implant. The surgical tool further includes a counter-torque sleeve extending around the output shaft having a proximal end and a distal end opposite the proximal end, wherein the proximal end is coupled to the housing and the distal end is configured to couple to the implant relative to the counter-torque sleeve. Upon a rotational force to the implant, the forces transmitted by the output shaft and the counter-torque sleeve are balanced by the coupling of the output shaft and counter-torque sleeve through the housing.

An example torque reaction tool includes a first arm having an end with a longitudinally extending cavity, and an opposite end with a first socket drive element disposed perpendicular to a longitudinal axis of the cavity. The torque reaction tool further includes a second arm having an end portion slidably disposed within the cavity, and an opposite end with a second socket drive element thereon, oriented in the same direction as the first socket drive element. The torque reaction tool further includes a first fastener, disposed in a first threaded hole in the first arm that extends into the cavity, the first fastener being adjustable to engage the end portion of the second arm to restrict sliding movement of the second arm relative to the first arm.

The present application thus provides a bolt tightening system. The bolt tightening system may include a bolt, a nut, and a bolt tightening tool. The bolt tightening tool may include an adapter and a chamber. One of the adapter and the chamber applies a torque to the bolt and one holds the nut.

A tool-change station includes a base, and a first tool-change member that is coupled to the base and is rotatable relative to the base. The first tool-change member includes a first tool-engagement portion, geometrically complementary with a tool-change-engagement portion of a tool of a rotary drive.

An immobilizer tool set includes a plurality of retention blocks. Each retention block of the plurality of retention blocks includes a first plate, a guide pin extending from the first plate, and a second plate on the guide pin and configured to slide on the guide pin relative the first plate. A spring is between the first plate and the second plate.

An example torque reaction tool includes a first arm having an end with a longitudinally extending cavity, and an opposite end with a first socket drive element disposed perpendicular to a longitudinal axis of the cavity. The torque reaction tool further includes a second arm having an end portion slidably disposed within the cavity, and an opposite end with a second socket drive element thereon, oriented in the same direction as the first socket drive element. The torque reaction tool further includes a first fastener, disposed in a first threaded hole in the first arm that extends into the cavity, the first fastener being adjustable to engage the end portion of the second arm to restrict sliding movement of the second arm relative to the first arm.

A rotary-drive sub-assembly includes a tool and a tool retainer. The tool includes a first body and a second body. The first body includes a tool-change-engagement portion and a first threaded portion that is fixed relative to the tool-change-engagement portion. The second body includes a fastener-engagement portion. The second body is translatable relative to the first body, co-axially with the first body, and is co-axially rotationally fixed relative to the first body. The tool further includes a keeper, fixed within the first body, and a resilient member, captured between the second body and the keeper. The tool also includes a tool retainer, including a second threaded portion, configured to be threadably fastened with the first threaded portion of the first body, and a key, fixed relative to the second threaded portion.

A method of processing a workpiece comprises identifying processing locations on the workpiece, drilling a first hole at one of the processing locations using a rotary drive, sensing a flow of fluid while drilling, generating an operation signal based on the flow, comparing the duration interval of the operation signal to a predetermined temporal value, and drilling a different hole at a different processing location based on the duration interval and the temporal value.

A tooling assembly for fastener installation has a socket body reversibly rotatable by a driving mechanism. A bore in the socket body has a first end portion and a central portion incorporating threads. A second end portion of the bore receives and engages a severable section of a frangible fastener. A pin is received in the bore and constrained from rotation by the driving mechanism. The pin has an ejection shaft with mating threads selectively receivable in the threads of the central portion of the bore. The socket body is freely rotatable with the mating threads positioned in the first end portion of the bore. Rotation of the socket body in torques the frangible fastener on a stud fracturing the severable section. Reverse rotation of the socket body engages the mating threads in the threads translating the pin. The ejection shaft ejects the severable section from the second end portion.

A surgical tool for removing a portion of an implant is provided that includes a housing, a motor contained within the housing and coupled to the housing, and an output shaft having a distal end and a proximal end opposite the distal end, wherein the proximal end is coupled to the motor and the distal end has an opening configured to rotatably engage an implant. The surgical tool further includes a counter-torque sleeve extending around the output shaft having a proximal end and a distal end opposite the proximal end, wherein the proximal end is coupled to the housing and the distal end is configured to couple to the implant relative to the counter-torque sleeve. Upon a rotational force to the implant, the forces transmitted by the output shaft and the counter-torque sleeve are balanced by the coupling of the output shaft and counter-torque sleeve through the housing.
