    摘要: An actuation device for a switch of a hand machine tool, particularly for a Totmann switch which provides for fatigue-free operation. The actuation device includes a front wall provided with a locking projection engageable in a recess formed in the wall of the switch housing. A restoring spring acts on an actuation member. Two spaced ribs with inclined surfaces are provided on the housing wall. The locking projection slides along the inclined surfaces of the spaced ribs. The locking projection may be broken away from the front wall of the actuation member whereby the end of the front wall would slide along the inclined surfaces of the ribs.

    摘要: An eccentric grinder having a small construction in the axial direction comprises an eccentric (15), which is driven so as to rotate, and a grinding plate (16) which is rotatably supported in the eccentric (15) and which can be set in rotation around its axis of rotation in one or the other rotating direction via rotating rings (26, 27), which are rigidly connected with the grinding plate (16), and via rolling rings (30, 31), which are arranged at the grinder housing (10), in order to change its grinding action. The selection of the rotating direction is determined by means of a manual switching device (38). For this purpose, the rolling rings (30, 31) are held at the grinder housing (10) so as to be rotatable and are in continuous engagement with the rotating rings (25, 26) fastened at the grinding plate (16). By means of the switching device (38), one of the rolling rings (30, 31), as desired, can be secured against rotation at the grinder housing (10) so that a rolling movement of the grinding plate (16) on the respective secured rolling ring (30, 31) results, or the two rolling rings (30, 31) can be released so as to rotate freely (FIG. 1).

    摘要: A clamping device for portable grinding machines comprising a clamping nut which can be screwed on to the end-side threaded step (13) of the drive spindle (10) to clamp a grinding disk (15) in place. The clamping nut carries a clamping fork (22) which, with its fork leg ends (26, 27), is held so as to be movable about a diametral pivot axis (30) between a clamping position and a loosened position. The ends (26, 27) are provided with eccentric pressing surfaces (28, 29) which decrease with regard to the eccentricity during the pivoting from the clamping position to the release position and act axially on the grinding disk (15) via a pressing disk (36). For releasing, the clamping fork (22) is pivoted about the pivot axis, surface areas of decreasing eccentricity of the pressing surfaces (28, 29) becoming effective. In the process, the thread (14, 20) is relieved and the clamping nut loosened, which can be fully unscrewed manually by taking hold of the clamping fork (22). This enables a grinding disk to be changed quickly and safely without a tool (FIG. 1).

    摘要: An electric power machine, particularly an angle grinding tool is provided with a centrifugal overspeed protecting device including a fly weight in the form of a severing blade which interrupts a power supply conduit when the rotary speed of the machine is excessive. The protective device includes a cylindrical housing attached face to face to the shaft of the electric motor. The severing blade is in the form of a quadrangular frame defining a center opening. The cylindrical housing is provided with a diametric through bore of a rectangular cross-section matching the frame-like severing blade. A blind bore of a circular cross-section is coaxially superposed on the rectangular through bore and its upper part is formed with inner thread for receiving a setting screw. A helical tensioning spring is inserted in the center opening of the frame-like severing blade and rests on the bottom of the blind bore to urge the centrifugal severing blade against the setting screw. When the rotary speed of the shaft and thus of the housing exceeds a predetermined value the severing blade is displaced by centrifugal force out of the rectangular through bore and severs a conduit in the power supply circuit for the motor whereby the compressed biasing spring acts as a buffer. The setting screw adjusts the distance on the center of gravity of the severing blade from the axis of rotation of the motor shaft and thus determines the value of the limit rotary speed.
