A reaction arm for use with a torque generating device, the reaction arm including a reaction bar, and a body portion having a first internal diameter, and having formed on an internal surface thereof a female spline having a second internal diameter and a guide bushing having a third internal diameter, the first, second, and third internal diameter being distinctly sized.

A more reliable and fool-proof method and apparatus for assembling an article of assembly (e.g. with predetermined screw torque requirements) in which the article of assembly has multiple fastening locations. The method comprises holding the article of assembly fixed while providing at least two different types of targets fixed relative to the article of assembly that correspond to the individual fastening locations. Fasteners are fastened into the article of assembly at the fastening locations. When fastening is occurring at one of the fastening locations, one of the targets is being sensed. Based on the target sensed, a target output is generated that differentiates between different types of targets thereby indicating fastening location of the fastening tool. The electronic target output is used for electronic control such as for stopping a conveyor to keep the article of assembly at an assembly station until the fastening operations have been completed.

A router includes a housing and a motor assembly disposed within the housing. The motor assembly includes a driven shaft having a cavity on a first end of the driven shaft. The router includes a collet that is configured to mate into the cavity of the driven shaft with the collet being configured to grip a shank of a router bit. The router includes a gear mechanism that is configured to couple and decouple from a second end of the driven shaft such that a rotation of the gear mechanism when the gear mechanism is coupled to the second end of the driven shaft causes at least one of tightening and loosening of the collet.

The disclosure relates to methods and tools for handling a component, the tools (10) comprising a first clamp seat (12) for receiving a first surface of the component and a second clamp seat (14, 16) for receiving a second surface of the component, the second surface being opposite to the first surface. The tool further comprises an actuator (45) for moving the first clamp seat to clamp the component between the first clamp seat and the second clamp seat with a predetermined clamping force, and an electric motor (40) for driving the actuator (45). The tool (10) further comprises a control configured to determine currents in the electric motor and to control the electric motor to provide the predetermined clamping force based on the determined currents. Also methods for determining a desired current level in an electric motor driving an actuator for clamping a component and methods for controlling a clamping force in a tool are provided.

A squeezer holder device for the holding a hand rivet squeezer on a bench top for improved part control and squeezer operation. The squeezer holder device also provides convenient storage for a hand squeezer and associated dies. The central feature of the invention is the simple slot and die holders designed into a single block. The squeezer holder device allows the user to position a squeezer on any benchtop at a user selected orientation. The squeezer holder device enables accurate control of parts with one hand throughout squeezer operation by using the table surface to operate the lower squeezer lever. The squeezer holder device can be easily slid around a benchtop with the squeezer and dies between operations. When squeezer use is completed the squeezer holder device holds the squeezer in an upright space saving position with associated dies.

A multi-axis support cart includes a base having a longitudinal axis and a second axis defining a first plane with wheels coupled to the base facilitating movement of the base along the first plane. Coupled to the base is at least one telescoping riser extending along a third axis orthogonal to the first plane. A support surface is coupled to the at least one telescoping riser and configured on a second plane parallel to the first plane with a piston coupled between the base and the support surface facilitating movement of the support surface along the third axis. A turntable coupled to the support surface receives a device/tool and provides rotational movement for the device/tool about the third axis.

A handheld drill press device includes a spine with a longitudinal section having a geared rack located thereon and a transverse section configured to receive and be coupled to a handheld drill. A carriage frame is slidably coupled to the spine and includes a workpiece connection interface located about the carriage. A gear and a lever handle are both rotatably coupled to the carriage frame wherein the gear is operable to mesh with the geared rack and the lever is configured to provide a torque to the gear and thereby move the carriage frame with respect to the spine.

A pneumatic mechanism includes: a casing having a main body and a base seat; a drive mechanism disposed in the main body; a first air bypass disposed in the main body, a rear end of the first air bypass communicating with the drive mechanism; a second air bypass having a rear end positioned on the base seat; at least one airflow passage disposed on the base seat, one end of which communicating with the second air bypass; at least one sucker disposed on the base seat; and at least one air-sucking passage disposed between the base seat and the sucker. One end of the air-sucking passage communicates with the air chamber of the sucker, the other end communicates with the airflow passage. The pneumatic mechanism is powered by one single power source to operate and produce sucking force.
