Definitions

  • the invention describes an at least partially rotating and striking Electric hand machine tool, in particular a combination hammer or one Chisel hammer with chisel positioning.
  • the axial Rotatability represents a degree of freedom of movement which, when appropriate Usually used by a previously rotatable tool Locking rotation is prevented.
  • a combined electric hand machine tool has one a rotatably lockable mode selector switchable operating mode ⁇ chisel position >> on, in which to position the chisel on the Tool spindle attached tool holder is freely rotatable.
  • operating mode ⁇ Chisels>> the tool spindle is fixed near this rotational position.
  • the rotary position of the chisel must first be in the passive operating mode ⁇ Chisel position >> switched, then the chisel manually positioned and then back into the Operating mode ⁇ chisels>> can be switched, which means that the user can reach around several times got to.
  • the object of the invention is to implement a comfortable rotary positioning of a striking tool in an electric hand machine tool.
  • Another aspect consists in a signaling means suitable for an electric hand machine tool.
  • a tool spindle with a tool holder can be switched optionally drives rotating and / or striking, one controllable with a signaling means and with the Electric motor electrically connected rotational displacement means for the active rotational displacement of the Tool spindle on.
  • Electric motor is the rotational position at least in an optionally switchable operating mode the tool spindle and thus also the tool holder or one rotatably in it introduced tool actively rotatable by the electric hand machine tool, wherein the rotational displacement is defined by an angle of rotation less than 360 °, which is over a limited, user-controllable time interval between 0.3 and 30 seconds by a slow rotation is caused.
  • the rotational displacement means is advantageous as one for generating a rotational displacement suitable motor electronics, in particular producing the slow rotary movement formed, whereby the rotational displacement means by the around a motor control algorithm for a slow rotary movement, for example with a clocking of the motor phases in the area between 1 to 10 Hz, advanced motor electronics can be realized.
  • the signal means with a mode selector switch for selecting the operating mode is advantageous connected to be activated by at least one switch position, whereby a with respect to the Electric hand machine tool active operating mode for rotating the Tool spindle can be selected manually, in particular the ⁇ active chisel operating mode >> position.
  • the switch position assigned to the active rotational displacement within an is advantageous due to the degree of freedom of movement of the mode selector switch immediately adjacent to an exclusively striking operating mode, whereby especially between the operating modes: ⁇ chisels>> and ⁇ active chisels position >> can be changed immediately.
  • the switch position assigned to the active rotational displacement is not advantageous self-locking, which means that this operating mode can be used for a longer period of time is difficult.
  • the signal means is advantageous as an alternative or in combination as a voltage sensor formed, which is connected to a power line in the circuit of the electric motor, whereby over a defined voltage range, e.g. for service purposes below 50 V, Maintenance activities in the slowly moving mechanical area of the Electric hand machine tool are supported.
  • Electric motor 1 has a rotating and striking electric hand machine tool with a Electric motor 1, which has a tool spindle 4 via a striking mechanism 2 and a gear 3 with a tool holder 5 optionally rotatable and / or driving, one controllable with a signaling means 6 and electrically connected to the electric motor 1
  • Rotational displacement means 7 in the form of motor electronics with a clocking of the motor phases in the range between 1 to 10 Hz for active rotational displacement of the tool spindle 4.
  • the signaling means 6 designed as a HALL sensor is provided with a mode selector switch 8 Selection of the operating mode with a switch position A ⁇ active position chisel >> activatable connected, which is not self-locking within a by the Degree of freedom of movement of the mode selector 8 mandatory switching sequence immediately next to it the operating mode B ⁇ chisels>> is arranged.
  • the signal means 6 ' is also as Voltage sensor formed, which with a power line 9 in the circuit of Electric motor 1 is connected.
