Definitions

  • the invention describes an at least partially axially striking Electric hand tool device such as a drill bit or chisel device for dismantling Rock.
  • Performance parameters for the mining performance are in particular Impact strength, impact frequency and optionally the speed of the impact tool.
  • control functions of the electric hand tool device are in the Guide handle or arranged in the auxiliary handle.
  • the grinderless potentiometer in the actuator between the pressure plate and the sensor compressible medium arranged in the form of a fluid for pressure transmission.
  • US4250434 is an electro-pneumatic sensor used to control a machine designed as an elastic pressure hose.
  • DE19703746 is on the rear Handle shell on the handle of an electric hand tool device a damping element arranged.
  • a fluid-padded handle has a pressure sensor on which to control the pump to generate the vibration damping filling pressure serves.
  • the axial impact energy is one with an actuator on the housing Infinitely adjustable hammer drill.
  • DE4231986 there is a mechanical Control of the coupling of the hammer mechanism of a rotary hammer via the contact pressure of the Electric hand tool device to the workpiece. The necessary to each other reduce moving parts sliding in the rough environment of the Construction industry, for example, by registered dust, the reliability of the Electric power tool.
  • the object of the invention is a sliding movement-free implementation for intuitive Control of the performance parameters, especially the axial impact energy, one at least partially axially striking electric hand tool device.
  • Another aspect consists in reducing the vibrations transmitted to the user's hand.
  • an at least partially axially striking electric hand tool device a handle and an electronic control means for at least one performance parameter on which is from a flat force sensor, which is between two, at least partially transversely arranged to the flapping axis, assigned to each other pressing surfaces and the contact pressure exerted by the user on the handle in the direction of the workpiece is recorded without sliding movement, is controllable.
  • the flat force sensor is advantageously designed as an electropneumatic sensor, which is a hollow pneumatic between a pressure surface and the force sensor element Has power transmission link, which is very simple, sensitive and robust.
  • the force transmission member with an easily deformable or fluid is advantageous Pressure transmission medium filled, for example a pneumatic oil, a gel or a high viscoelastic solid, which is free of evaporation and not freely flowable.
  • the hollow pneumatic force transmission element is advantageous as a cushion or hose formed, the cross sections of which are compressed by the contact pressure and thereby be deformed such that the hydrostatic pressure of the pressure transmission medium increases.
  • the flat force sensor at the front in the electric hand tool device is advantageous below the axial one Storage of the tool holder, for example, the spindle ball bearing arranged, whereby the total contact pressure is measured.
  • the power transmission member is advantageously extended to the handle, which makes the measurement the total contact pressure on the force sensor element in the handle is possible.
  • the press surfaces are advantageous with regard to the flow of force between the striking mechanism and arranged the grip surface of the handle, further advantageously on the tool-side axial Fixing the striking mechanism to the outer housing shell with the handle or on the Modular definition of the drive module for the handle module with the handle.
  • the force transmission member is advantageously flat and transverse to the axis of impact further advantageous between the handle and a vibration-dampened handle shell arranged, which dampens vibrations within the pressure transmission medium and are therefore only transferred to the hand of the user to a reduced extent.
  • the side handle with such a force transmission element is also advantageous Formation of a flat force sensor designed which with another Force sensor element provided and electrically via signal lines with the Force sensor element of the handle is connected, which in total the contact forces both the handle and the side handle can be used for control.
  • the force transmission element of the side handle is advantageous directly via a Pneumatic connection hose with the power transmission element of the handle connected, whereby a common force sensor element is sufficient and none in the live part of the front part of the hand tool device are necessary, thereby avoiding security problems in this regard.
  • the flat force sensor via a low-pass filter with a cutoff frequency is advantageous less than 30 Hz connected to the control means, which the low-frequency control signals filtered out and suppressed the higher-frequency vibrations.
  • FIG. 1 shows an axially striking electric hand tool device 1 with one Striking mechanism 2 driving electric motor 3 a handle 4 and a Phase angle control trained electronic control means 5, which with a flat force sensor 6 arranged perpendicular to the flapping axis A, which detects the User exerted contact force F on the handle 4 in the direction of the workpiece is recorded without sliding movement, is controllably connected.
  • the force sensor 6 is located without sliding movement between two mutually associated pressing surfaces 7a, 7b, which are arrange between the striking mechanism 2 and the grip surface 8 of the handle 4. schematically the advantageous pressing surfaces 7a, 7b and.
  • Force sensor 6 each at I on the axial fixation of the striking mechanism 2 on the tool side to the outer housing shell 9 the handle 4, at II on the modular definition of the drive module 10 to the handle module 11 with the handle 4 (force sensor 6 "') and at III between the handle 4 and one arranged by the flat force sensor 6 vibration-dampened handle 12.
  • On Force sensor 6 'in the side handle 13 is direct via the connecting hose 14 pneumatically connected to the handle 4.
  • the annular force sensor 6 is at the front in the electric hand tool device 1 in the area of the axial mounting of a tool holder 20 arranged in the spindle ball bearing 21 and with the connecting hose 14 to Handle 4 extended, or connected to the sensor 6.
  • the force sensor 6 is in the exit
  • a low-pass filter 19 is connected downstream of the control means 5 (FIG. 1).
  • the flat force sensor 6 is designed as an electropneumatic sensor, which is a hollow between a pressure surface 15 and the force sensor element 16 has pneumatic power transmission member 17, which with an easily deformable Pressure transmission medium 18 is filled and formed as a flat hose is.
