For a machine tool designed in particular as a saber saw, a configuration including a carrying frame is provided, via which the lifting rod and the support element are joined to form a unit that can be rotated about the longitudinal axis of the power tool, is mounted on the casing side, and guides a drive part of the lift drive on the lifting rod side.

Motor-driven machine tool

The invention relates to a power tool (), especially in the form of a hand-held jigsaw (). In order to allow for a semi-autonomous operation which assists the user to guide the tool, the tool is provided with a sensor system () for observing a detection surface () within which the desired working direction is detected as a path default () for the saw blade () serving as the tool () with respect to its alignment relative to the jigsaw (), the detected path default being intended for downstream control means (). Said control means align the saw blade () relative to the path default () by rotating it about its longitudinal axis () so that the user guiding the saw blade () only has to make sure that the path default () extends inside the detection surface ().

Power tool, particularly a hand-held power tool

The disclosure provides a transverse guide of a saw blade for a machine tool, particularly for a hand-guided machine tool in the form of a band saw or jigsaw, wherein the saw blade can be rotated about the longitudinal axis thereof by way of said guide in the opposite direction to said forces as a function of transverse and/or torsional forces acting on the saw blade.

Power tool, in particular a portable power tool

A hand-held jigsaw includes a saw blade and control element for automating a tracking the saw blade, the hand-held jigsaw, or both along layout lines. A sensor, preferably a camera unit, detects a layout line provided on a work piece.

Hand-held jigsaw

The invention relates to an electrical machine tool, particularly a hand machine tool, having a contrast detection device, an analysis unit, and at least one sensor provided for capturing a surface of a work piece. According to the invention, the analysis unit is provided for detecting a differentiation of the surface from an at least partially automatic guide using data captured by a sensor.

Electrical machine tool

A power tool, particularly a hand-held power tool, is provided with a sensor unit for sensing an observation area on the workpiece side with varying resolution and having arranged in front of it a lens system with lenses of varying focal length.

Machine tool, particularly a hand-held power tool

A machine tool, in particular a sawing machine, is described, having a work surface () for placing a workpiece () to be machined and a tool support unit () for supporting a tool (), the tool support unit being supported movably relative to the work surface (). The machine tool includes a tool operation monitoring device () for monitoring a tool range () at least during tool operation, the device having an imaging unit ().

Machine tool

A handheld jigsaw, such as a compass saw (), is disclosed that comprises a housing () and a lifting rod () having a pendulum mechanism (). The pendulum mechanism includes a pendulum lever () with which a pendulum stroke can be given during sawing to a saw blade () carried by the lifting rod (). The lifting rod () is arranged such that it can rotate about its own axis () thereof and pivot transversely to the axis (), and wherein the pendulum mechanism () can rotate about the axis ().

Hand-held power jigsaw

A power tool includes a lighting unit directed towards a detection field on a workpiece side, and a detection system that emphasizes the contrast between a marking applied to an underlying surface and the underlying surface.

A handheld power tool having a power tool that executes a reciprocating motion, in particular a reciprocating power saw with a reciprocating sawblade (), is disclosed. To prevent the power tool from sawing untrue during the cutting operation, in particular between the upper and lower cutting edges, the power tool is assigned at least one force transducer (), which measures the magnitude of a transverse force, oriented transversely to the direction of motion, that occurs at the power tool, and at least one actuator (), which acts on the power tool as a function of the measured magnitude of the transverse force, is provided for transverse force compensation (FIG.).

Handheld power tool

A protective device for use with table-top circular saws that operate a tool designed as a rotating, disk-shaped sawing tool includes at least one actuator unit and at least one protective unit. The at least one actuator unit moves the protective unit into a protective position on the tool.
