摘要:
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.
摘要:
The invention relates to a power tool (1), especially in the form of a jigsaw (2), which comprises a saw blade (8). The back (39) of said saw blade is supported by a supporting member, which, even when in the shape of a supporting roller (36, 37), allows a controlled support of the saw blade (8) both in the pendulum stroke mode and in the scrolling mode.
摘要:
The invention relates to an operating method for a power tool (1), whereby it is monitored whether the working tool (7) has reached a predetermined position of application relative to a workpiece and whether it has maintained said position of application over a minimum period (t) and the tool (1) is only released for the working operation once the minimum period has expired.
摘要:
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.
摘要:
A machine tool system is provided with a detection device for a working line specified for the surface of a workpiece, the marking contour of the working line being viewed from different wavelength ranges.
摘要:
A power tool, particularly in the form of a keyhole saw, is provided with a sensor device that senses the position of the tool, in particular the reciprocating position of the saw blade in at least one of the reversal positions.
摘要:
The invention relates to a hand-held jigsaw, especially a compass saw, having a housing and a lifting rod with a pendulum mechanism, especially a pendulum lever, with which a pendulum stroke can be given during sawing to a saw blade carried by the lifting rod, especially a jigsaw blade. According to the invention, the hand-held jigsaw can be used more safely and in more special applications as the lifting rod is arranged such that it can rotate about the axis thereof and pivot transversely to the axis, and the pendulum mechanism can rotate about the axis.
摘要:
The invention relates to a power tool (1), which is designed as a jigsaw (2) and which comprises a rear support (2) for the saw blade (8) at a right angle to the rotational axis (22) of the saw blade (8). Said support (20) is designed as an element that is carried along by the saw blade in the rotational direction.
摘要:
The invention relates to a power tool (1), especially in the form of a hand-held jigsaw (2). 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 (27) for observing a detection surface (31, 43) within which the desired working direction is detected as a path default (23) for the saw blade (8) serving as the tool (7) with respect to its alignment relative to the jigsaw (2), the detected path default being intended for downstream control means (26). Said control means align the saw blade (8) relative to the path default (23) by rotating it about its longitudinal axis (25) so that the user guiding the saw blade (2) only has to make sure that the path default (23) extends inside the detection surface (31, 43).
摘要:
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.
