Definitions

  • the present invention relates to a hand tool according to the preamble of claim 1.
  • a hand tool is known from DE 42 13 610 A1 known.
  • One from the DE 201 03 600 U1 Known hand tool is a compressed air tool with a rotatably mounted in a housing turbine.
  • the turbine has a rotor which is adapted to be driven by compressed air and which is non-rotatably coupled to a tool holder.
  • the hand tool further includes a valve configured to control a supply of pressurized air to the rotor, a brake adapted to brake the rotor, and an actuator configured to coordinate the valve and the brakes so to actuate that the brake brakes the rotor in a closing position of the valve which interrupts the supply of compressed air.
  • the actuating element of the known hand tool is a slide switch in the form of a sliding sleeve, which is slidably mounted on a tubular portion of a D.ruckluft leading part of the hand tool.
  • the tubular portion has an end pneumatically connected to the rotor and an end adapted for connection to an external compressed air supply.
  • the two. Ends are pneumatically separated within the tubular portion, but have radially outwardly facing compressed air channels which pierce an outer surface of the tubular portion and which are sealed by the sliding sleeve against the environment.
  • the resulting openings on the outer surface of the tubular portion have an axial distance in the direction of a tube axis of the tubular portion, so that there is no connection between its two ends within the tubular portion.
  • the sliding sleeve has in its inner surface an annular groove whose axial extent is at least as large as the axial distance of said openings.
  • the Sleeve axially displaced so that the annular groove connects the openings of the radially outwardly facing channels of the two ends of the tubular portion with each other.
  • the sleeve is displaced so that the annular groove is at least not more than two openings, so that the openings are no longer connected via the annular groove.
  • the control and Ab juryn the compressed air supply is thus carried out via a displacement of the sleeve, which corresponds to a clearance of the opening of a radial compressed air channel. In relation to the total displacement of the sliding sleeve, this clear width is relatively small, so that the Aufberichtn and Ab juryn more similar to a digital switching on and off the compressed air supply as a gradual take-off and Ab juryn.
  • the brake of the known hand tool has an annular friction lining, which is connected via coaxial with the axis of rotation of the rotor arranged control pins translationally rigid with the sliding sleeve.
  • the rotor itself has an annular end configured as a contact surface for the friction lining.
  • the slide switch is pushed away from the rotor. Then the friction lining is first lifted off the annular face while the compressed air supply is still closed. This is followed by a free travel, in which the sliding sleeve is moved translationally, without causing a take place via the annular groove pneumatic connection of the two ends of the tubular portion. Subsequently, the compressed air supply is opened by a displacement of the sliding sleeve, which corresponds to a clearance of the opening of the radial compressed air ducts in the direction of displacement.
  • the object of the invention is to specify a hand tool of the type mentioned, which is characterized by better handling during operation.
  • actuating element is a rotatable control sleeve which is adapted to coordinate the brake and the pressure fluid supply to control so that the valve is driven in parallel to a release of the brake.
  • actuating element is a rotatable control sleeve which is adapted to coordinate the brake and the pressure fluid supply to control so that the valve is driven in parallel to a release of the brake.
  • the realization of the actuating element as a rotary sleeve has the advantage that a rotational movement for the adjustment of the hand tool mentioned above is subjectively perceived as ergonomic.
  • the interaction of adjusting torque and the torque of the hand tool causes in the rotatable control sleeve with respect to the translationally moving sliding sleeve better and more sensitive haptic feedback, as superimposed on the manually applied adjusting torque with a resulting change in torque of the hand tool.
  • the better haptic feedback in particular improves the controllability of small changes in the drive power, which improves handling by improving the metering.
  • a brake-adjustment-rotational angle characteristic of the control sleeve in a first rotation angle range in the vicinity of the closed position of the control sleeve is steeper than in a second, further away from the closed position rotational angle range, is a fast separation of the brake when turning on and a late Closing the brake when controlling the compressed air supply ensured. Due to the steeper course, the opening of the brake when opening the compressed air supply takes place early and quickly, that is, over only a small rotational angle range of the sleeve. Similarly, the closing of the brake is late and fast. Overall, despite the parallel operation of the valve and the brake taking place under the influence of a compressed air drive rubbing the friction surfaces of the brake largely avoided, so that improved metering of compressed air supply is not at the expense of the life of the brake.
  • a preferred embodiment is characterized in that the control sleeve is adapted to allow a control and Abgnaung the compressed air supply over a larger rotation angle range done as a release and actuation of the brake.
  • the control takes place in particular via a rotation angle range of the control sleeve, which extends beyond a rotational angle, in which the brake is already completely dissolved.

  • the radial turbines 46, 48, 50, 52 are rotatably coupled to the spindle 42 of the rotor 32 and therefore drive the rotor 32 at.
  • the illustrated Embodiment follows the rotationally fixed coupling by axial clamping of the radial turbines 46, 48, 50, 52 with the spindle 42 by a clamping nut 66th
  • the turbine speeds can reach min -1 in an order of 100 000th When switching off the compressed air supply, it then continues to run for, for example, about 30 seconds. This results in a safety and injury risk during handling.
  • the hand tool 10 has a brake, which in the FIG. 3 as a pair of a friction plate 68 and a pressure plate 70 is partially visible and will be explained in more detail below.
  • the compressed air valve 45 in the illustrated embodiment is a ball valve having a ball 72 which is urged by a resilient member 74, for example a spring, onto a circular supply port of a compressed air channel 76 to close that opening.

  • valve pin 78 itself is guided substantially radially in a guide within the valve body 77. With respect to a longitudinal axis 86 of the hand tool 10, the distance of that control surface of the valve guide track 84, which faces the second end 82 of the valve pin 78, of the longitudinal axis 86 of the hand tool from the rotation angle of the control sleeve 18 is dependent. This means that the inward and outward movement of the valve pin 78 is controllable by a rotation of the control sleeve 18.
  • FIG. 3 shows a closed position of the valve 45.
  • the control sleeve 18 is rotated about the axis 86 around. Due to the design of the guide track 84, the valve pin 78 is initially pressed radially inwardly against the ball 72. Upon further rotation of the control sleeve 18, the valve pin 78 then pushes the ball 72 laterally (ie in the FIG. 3 upward) out of the closed position so that compressed air can flow past the ball 72 past the central inlet air opening into the compressed air channel 78.

  • the brake is activated when the control sleeve 18 is rotated in a direction abscursing the compressed air supply and thus closing direction.
  • the brake pin 96 slides in the figure 11 upwards, or outwards, and allows the brake springs 110 to press the pressure plate 108 against the friction lining 112.
  • the brake is thus realized as a spring brake in which the braking force is applied by springs and is released against the force of the springs. This has the advantage that the closing twisting the Control sleeve 18 is automatically braked, even if no manual force is applied when the control sleeve 18 is closed.
  • Fig. 9 shows the subject of the Fig. 8 in a rotated about the longitudinal axis 86 by 90 ° view.
  • the displacement of the brake axes 105 by 180 ° has the advantage that the brake axes 105 can be distributed around the circumference, so that the central compressed air supply to the rotor can be maintained.

  • the closed position corresponds to the subject of FIG. 10 the rotation angle 0 of the control sleeve 18.
  • the second rotation angle range is the Range between about 32 and about 110 °, in which the characteristic 114 is not only less steep, but in the case shown even without slope.
  • the course of the characteristic curve 116 shows how the entire angle of rotation range of 0 ° to 110 ° of the control sleeve 18 is used to regulate the supply of compressed air. This results in the already mentioned improved meterability.
  • the control of the compressed air supply which takes place in parallel with releasing the brake, permits an expansion of the adjustment path of the actuating element during the metering of the compressed air supply, which likewise leads to an improvement in the meterability and thus also in the handling.
  • Both characteristic curves 114, 116 have different angular ranges for the angle of rotation of the control sleeve, in which the respective characteristic has a non-zero slope.
