  • Publication number: 20250354576
    Abstract: A connector mechanically connects a first workpiece and a second workpiece. The connector is plate-shaped or flat bar-shaped and has a first engagement element for engaging a first undercut of a first coupling groove and a second engagement element for engaging a second undercut of a second coupling groove. Moreover, the connector has an actuation body for selectively bringing the connector in a connection state in which the first engagement element is positioned to engage the first undercut and the second engagement element is positioned to engage the second undercut, and for selectively bringing the connector in a release state in which the first engagement element is configured to be withdrawn from the first undercut and the second engagement element is configured to be withdrawn from the second undercut. An actuation interface is provided on the actuation body. The actuation interface is arranged eccentrically along an insertion direction (D).

  • Publication number: 20250339908
    Abstract: A tool device including a stationary part and a shifting part which has a tool and which can be shifted relative to the stationary part and in the process carries out a shifting movement in order to set a position of the tool relative to the stationary part, and a guide means which is designed to guide the shifting part relative to the stationary part during the shifting movement. The guide means includes a guide structure that defines a movement path, and a guide part that rests on a guide contour of the guide structure and that can be moved along the movement path in order to carry out the shifting movement. The tool device includes a pressing mechanism which has a spring element which is designed to press the guide part against the guide structure, in order to reduce or eliminate play between the guide part and the guide.

  • Publication number: 20250153389
    Abstract: A sawing device, in particular a circular saw bench, having a saw blade, a riving knife receptacle and a riving knife, which can be inserted into the riving knife receptacle in order to assume a work position behind the saw blade. The sawing device has a locking mechanism which can be set into a locking state by an insertion movement, directed in an insertion direction, of the riving knife into the riving knife receptacle, in which locking state the riving knife is locked by the locking mechanism in the riving knife receptacle with respect to a removal direction opposite to the insertion direction.

  • Publication number: 20250144838
    Abstract: A stop unit including a stop body extending in the longitudinal direction; and a fastening device having a first fastening mechanism and a second fastening mechanism for fastening the stop unit to an electric tool and which are arranged spaced apart from one another in the longitudinal direction. The stop unit further includes an operating element, which is coupled to the first fastening mechanism and the second fastening mechanism and can be made to perform a first operating-element movement, by means of which the fastening device can be sequentially shifted first into a first fastening state and then into a second fastening state, in which in the first fastening state the first fastening mechanism is in its fastening position and the second fastening mechanism is in a release position, and in which in the second fastening state the first and the second fastening mechanism are in the relevant fastening position.

  • Publication number: 20250135564
    Abstract: A sawing device, in particular a circular saw bench or crosscut saw, including a workpiece support for supporting a workpiece, a saw blade, and an electrical actuator device for setting a saw blade position of the saw blade relative to the workpiece support. The electrical actuator device has a first electrical actuator which includes a first rotor and serves to set the saw blade position in a first degree of freedom, in particular a saw blade angle, and the sawing device is designed to detect a current saw blade position of the saw blade on the basis of a first rotor movement of the first rotor.

  • Publication number: 20060248885
    Abstract: An apparatus and method for controlling a work tool on a work machine are provided. The work machine may have first and second actuators, each actuator being operable in a vibratory mode and a non-vibratory mode, and each actuator being coupled to the work tool for changing the position of the work tool. The method may include simultaneously (i) operating the first actuator in a vibratory mode, (ii) operating the second actuator in a vibratory mode, and (iii) receiving a command to change the position of the work tool. The method may further include operating the first actuator in a non-vibratory mode to change the position of the work tool while operating the second actuator in a vibratory mode to vibrate the work tool, in response to receiving the command.
