    摘要: A motor-driven hand drill includes a housing, in which between a motor and a drill receptacle, a safety coupling for limiting a torque, applied to a drill, is positioned. For specific conditions, for example for drilling in armoring iron, the torque applied to the drill must be increased. The drill is provided with an electro-magnetic device which is operatively connected to the safety coupling to adjust the limiting torque applied to the drill. The magnetic device is actuated by means of a pushbutton positioned in the same gripping region as the pushbutton for actuating an electric motor of the drill to switch the same on and off.

    摘要: In a drill hammer a motor driven striking mechanism is provided with two air cushions of changeable volumes, through which impact energy is transmitted from the motor to a reciprocating striker which in turn transmits the energy to a tool of the drill hammer. When the striker moves in the direction towards the tool both air cushions act on the striker whereas when the striker moves away from the tool only one of two air cushions acts on the striker.

    摘要: A tool chuck for a hammer drill has an inner sleeve and an axially slidable outer sleeve concentrically surrounding the inner sleeve. The inner sleeve has an open leading end adapted to receive a shank of the tool. The shank is clamped in the inner sleeve with a snap action in response to insertion of the shank through the open end. Torque and/or axial impact are selectively imparted to the tool chuck from a drive of the hammer drill. The tool shank is formed with a radially outwardly opening recess closed at both axial ends and shaped to receive a tool-holding element and with at least one axially extending groove. A formation is formed in the inner sleeve which is engageable with the axially extending groove for torque transmission. A ring is positioned between the outer sleeve and the inner sleeve. The ring is movably biased by a spring in axial direction and is provided with a projection engageable with the tool-holding element when the latter is moved outwardly of the recess.

    摘要: A hammer drill has a chuck forming a tool receptacle defining a chuck axis and provided with a tool-holding element radially displaceable into a position protruding into the tool receptacle. The tool has a shank defining a tool axis receivable axially in the receptacle. This shank is formed with a radially outwardly opening recess closed at both axial ends and shaped to receive the tool-holding element, and with an axially extending groove separate from the recess and opening axially at the end of the shank. This groove has at least one flank extending substantially radially of the tool axis. A rotary-entrainment formation in the receptacle is formed with at least one side flatly engageable with the flank for maximum force transmission and minimum wear.

    摘要: A device on machine tools for transmitting a rotational and/or percussive movement to a tool (22) has two or three rotational drivers (14) which are arranged so as to be symmetrical with respect to rotation. The rotational drivers (14) are stepped and flank parts (16) extending radially to the center axis (15) alternate with guide portions (17) extending along a cylindrical outer surface. Locking members (20) which engage in depressions (28) at the tool (22) are arranged in the region of the rotational drivers (14) for the axial locking of the tools (10). With the tool holder (10) according to the invention, tool shafts having diameters between 8 and 12 mm can be clamped without converting or modifying the tool shafts. Good true running characteristics can be achieved in spite of the stationary rotational drivers (14).

    摘要: A chuck for use in a percussion drill or the like has a unit for securing the chuck jaws against unintentional loosening during operation. The securing unit moves from an unlocked position in which a tool can be received by the chuck jaws to a locked position automatically for drilling operations without the use of a key. The securing unit includes a first surface (22) upon which a sliding member (21) is slidable to be received in a recess (26) during the shaking caused by drilling, so that coupling members (15, 19) between a securing sleeve (17) and a clamping sleeve (13) engage with one another.

    摘要: A hand-held motor-driven percussion tool comprises a piston driven over an air cushion and acting over an axially movable anvil on the inner end of a tool axially movable in a tool receiver provided at one end of a tool housing. The anvil has an annular collar located in the cavity of an impact body which is movable in the direction of the impact of the piston against a cushioning ring. The impact body has an abutment face adapted to be engaged by a collar of the anvil when the latter is driven by the piston. A face of the impact body facing away from the cushioning ring is directed toward a part fixedly connected with the tool housing. The mass of the impact body is for instance 10% greater than that of the anvil. If the tool during operation is withdrawn from a workpiece, then the flange of the anvil impinges upon the abutment face of the impact body and accelerates the latter towards the cushioning ring. The anvil reaches in a region adjacent the impinging location a rest position, so that the piston will not engage the anvil any longer, and further striking of the percussion tool will cease.
