Definitions

  • the invention relates to a power tool with a housing, with a housing arranged in the drive motor with a motor shaft which defines a longitudinal axis with an oscillating driven by the drive motor work spindle for driving a fixable outside of the housing to a tool holder of the work spindle tool, said Work spindle oscillates about a spindle axis, which is arranged at an angle to the longitudinal axis, and with at least one storage unit for supplying the drive motor with energy.
  • Such a hand tool is from the US design patent Des. 386,378 known. It is an oscillating drivable triangular grinder with a housing, with a storage unit, with a gear head and with an oscillating drivable work spindle for driving a fixed spindle on the work spindle, the gear head, the housing and the storage unit along a longitudinal axis and the spindle axis are arranged perpendicular to this longitudinal axis. The tool is fixed outside the housing or the gearhead on the spindle axis.
  • oscillators can be used in a variety of ways, such as grinding, but also for sawing or cutting.
  • a typical oscillation frequency is in the range of about 5,000 to 25,000 oscillations per minute and a typical oscillation angle between about 0.5 ° and 7 °.
  • Hand tools according to the aforementioned type offer a high degree of flexibility with regard to their possible applications.
  • the memory unit enables power supply of the hand tool far away from cable networks.
  • the invention has for its object to provide a hand tool of the type mentioned with easy handling and a low level of vibration.
  • the storage unit has a center of gravity, which is arranged on a side facing away from the tool holder of the longitudinal axis.
  • the storage unit is used as a counterweight.
  • the vibration level perceived by the user may decrease, as well as the level of sound emitted by the hand tool may be reduced.
  • the handling of the hand tool is simplified.
  • center of gravity means the center of gravity of a body. It should be expressly mentioned that, for the purposes of the invention, the center of gravity coincides sufficiently precisely with the center of mass.
  • the storage unit based on its volume, arranged to more than 50% on the side facing away from the tool holder side of the longitudinal axis.
  • the drive motor between the work spindle and the storage unit is arranged.
  • the center of gravity of the storage unit is arranged on a plane spanned by the spindle axis and the longitudinal axis.
  • the storage unit is designed replaceable.
  • the flexibility of the hand tool increases. Conveniently, the user may carry additional loaded storage units to replace empty storage units after use.
  • the storage unit is provided with an end face facing the working spindle and an outer side surface adjoining the tool side, which has an at least partially flat portion which is at an angle between 5 ° and 60 °, preferably between 10 ° and 35 °, with the longitudinal axis , includes.
  • the storage unit is provided with a cover surface opposite the outer surface, which has an at least partially flat portion which encloses with the longitudinal axis an angle between 5 ° and 60 °, preferably between 10 ° and 35 °.
  • the housing on the side facing away from the tool holder of the longitudinal axis at the transition from the drive motor to the storage unit having an oblique transition region can continue to be used by the user.
  • the ergonomics will be further improved.
  • Fig. 1 is an inventive power-driven hand tool shown partially cut and designated overall by the numeral 10.
  • the hand tool 10 has a housing 18 in which a drive motor 26 is arranged.
  • the drive motor 26 has a motor shaft 28 that can be driven about a longitudinal axis 42.
  • the motor shaft 28 is mounted in the housing 18 by means of a schematically illustrated motor bearing 30.
  • the motor shaft 28 has an eccentric pin 32.
  • the eccentric pin 32 is as the longitudinal axis 42 radially offset shaft journals educated.
  • At its periphery of the eccentric pin 32 is a here schematically illustrated with spherical outer ring eccentric bearing 33 assigned.
  • a work spindle 12 is provided, which is mounted in its upper region by means of a spindle bearing 15 and in its lower region by means of a spindle bearing 16 in the housing 18.
  • a tool 20 is fixed by means of a fastening element 22 on a tool holder 13 in the lower region of the work spindle 12.
  • the connection can be made non-positively, non-positively and positively or in other suitable for transmitting a torque manner.
  • the work spindle 12 is driven to oscillate about a spindle axis 14, the associated pivoting angle is indicated by the double arrow 17. As mentioned above, the oscillation takes place with high frequency and low Verschwenkwinkel.
  • a rocker arm 24 is securely connected to the work spindle 12.
  • the oscillating lever 24 serves as a coupling member for transmitting the rotational movement of the motor shaft 28 to the work spindle 12.
  • the spindle axis 14 is arranged perpendicular to the longitudinal axis 42, as indicated by the angle ⁇ . It is understood that the longitudinal axis 42 and the spindle axis 14 can also include another, different from 90 ° angle ⁇ .
  • a storage unit 38 is removably attached to the housing 18.
  • the storage unit 38 serves to supply the drive motor 26 with energy.
  • two connections 34, 36 are provided on the drive motor 26.
  • the storage unit 38 has a center of gravity 40 which is arranged on the side of the longitudinal axis 42 facing away from the tool holder 13.
  • the storage unit 38 is provided in the direction of the drive motor 26 or the spindle axis 12 with an end face 44 and has an outer surface 46 and a cover surface 48, which are arranged parallel to each other.
  • the outer surface 46 encloses an angle ⁇ with the longitudinal axis 42.
  • the top surface 48 encloses an angle ⁇ with the longitudinal axis 42.
  • Embodiment of a hand tool according to the invention correspond to the angle ⁇ and ⁇ , it is understood, however, that the angle ⁇ and ⁇ can also differ.
  • the memory unit 38 is designed to be replaceable, as indicated schematically by a decoupled from the housing 18 storage unit 38 '.
  • oscillating tools according to the invention can be used in a variety of ways, they are characterized by high flexibility.
  • the application is multidirectional, be it horizontally on the floor, vertically on walls, overhead or diagonally in the room. To do this, the user must be able to assume a variety of grip positions on the hand tool.
  • the longitudinal arrangement of work spindle, drive motor and storage unit along the longitudinal axis has proven to be advantageous. In the embodiment shown, this arrangement is largely retained, however, a displacement of the center of gravity 40 of the storage unit 38 away from the longitudinal axis 42 is effected. This leads to the reduction of vibrations generated by the oscillation drive.
  • the housing 18 may have a "flowing" transition from the drive motor 26 to the storage unit 38.
  • This embodiment also allows the user a multidirectional use of the hand tool 10 with a variety of grip positions.
