An electrically driven orthopedic impactor may include an adapter for interfacing between the orthopedic impactor and a surgical implement. The adapter may have a first surface that transmits a forward impact energy and a second surface that transmits a reverse impact energy. The adapter can connect to the surgical implement and to the orthopedic impactor without the use of external tools. The adapter may connect to the orthopedic impactor via a pushing motion and may disconnect from the orthopedic impactor via a reciprocal sleeve. A sensor can communicate a spatial orientation of the adapter with respect to at least one reference point that is not located on the adapter or the orthopedic impactor. A communication device may transmit information to the orthopedic impactor related to frequency or impact energy settings based on a type of surgical implement attached to the adapter.

An attachment includes a body, an impact portion defining an impact axis and configured to receive repeated impacts from the powered hammer, and a driving portion including a side load driving portion and a top load driving portion that alternately receive the rod to transmit driving forces from the repeated impacts to the rod. The side load driving portion defines a side load driving axis that is offset from the impact axis. The top load driving portion includes a blind bore and defines a top load driving axis that is coaxial with the impact axis. The top load driving portion includes a sleeve disposed within the blind bore and configured to decrease wear of the blind bore during use.

An attachment configured for use with a powered hammer to drive a rod into the ground includes a body and an impact portion defining an impact axis. The impact portion includes a bore configured to receive a drive shank that is coupled to the powered hammer. The impact portion is configured to receive repeated impacts from the powered hammer. The attachment also includes a driving portion in which the rod is receivable. The driving portion includes a side load driving portion defining a side load driving axis. The side load driving axis is non-parallel to the impact axis.

A machine tool having a micro-hammering function. This micro-hammering function can be achieved either by a particular configuration of the machine tool (integrated solution) or by providing an external module between the machine tool and its tool (module solution). In micro-hammering, impact movements which superimpose a pure rotary movement of the tool of the machine tool and can thus increase, for example, a drilling force of the machine tool, are generated. The external module or the machine tool has cam disks, one of which is fixed to the shaft and the other to the housing. The cam disks can be made or interact in such a way that an impact movement is generated by way of which the rotary movement of the tool of the machine tool can be superimposed. An external module for generating impact movements and to a system of machine tool and external module.

A method of driving a rod into the ground comprises coupling an impact portion of an attachment to a powered hammer, positioning the rod between a first jaw of the attachment and a second jaw of the attachment, activating a first motor to move the first jaw toward the second jaw, such that the rod is clamped between the two jaws, and activating a second motor to drive an axial impact mechanism of the powered hammer to deliver repeated axial impacts to the impact portion of the attachment.

An adapter for coupling a tool bit to a power tool including a power tool housing. The adapter including an adapter housing configured to be coupled to the power tool housing and an input shaft supported by the adapter housing and defining an input axis. The input shaft is configured to be operably coupled to the power tool to receive rotary motion and axial impacts from the power tool. The adapter further includes a spindle supported by the adapter housing along an output axis oriented at an angle relative to the input axis and a transmission assembly operably coupled to the input shaft. The transmission assembly is configured to transfer rotary motion from the input shaft to the spindle for rotation of the tool bit. Moreover, the adapter includes an impact assembly having a wedge configured to transfer axial impacts from the input shaft to the tool bit.

A tool assembly and an attachment apparatus are provided, including a drive shaft extending along a longitudinal direction and forming a groove. A latch includes a notch configured to extend into the groove at the drive shaft. A coupler extends along the longitudinal direction and forms a cavity extending along the longitudinal direction. A tool end opening is formed at the first end of the coupler through which the drive shaft extends into the cavity along the longitudinal direction. The coupler forms a latch opening extending along the longitudinal direction and into the cavity. The latch is positioned in the cavity through the latch opening. A collar extends at least partially around the coupler. The collar is articulatable along the longitudinal direction around the latch opening.

A rotary hammer includes a housing including a motor housing and a secondary housing. The rotary hammer includes an output device configured to provide a rotational output, an axial hammering output, or both the rotational output and the axial hammering output. The rotary hammer also includes a transmission mechanism situated within the secondary housing. The rotary hammer also includes a light holder with a plurality of light sources distributed around an output axis of the rotary hammer. The light holder includes a ring portion mounted to a front surface of the secondary housing. The light holder also includes an extending arm that extends downward and away from the ring portion in a channel of the secondary housing. The rotary hammer includes lighting power wires that are located within the channel and that are covered by the extending arm.

A method of driving a rod into the ground includes coupling an impact portion of an attachment to a powered hammer. The rod is positioned between a first jaw of the attachment and a second jaw of the attachment. The first jaw is pivoted relative to the attachment such that the first jaw is engaged with the rod. The second jaw is pivoted relative to the attachment such that the second jaw is engaged with the rod. The powered hammer is activated to deliver repeated axial impacts to the impact portion of the attachment.
