  • this Measures becomes essentially wear-free Adjustment element realized, which also takes up little space required and therefore easily in the housing of a pulse screwdriver can be accommodated.
  • the invention Measures also achieved weight savings for a hand tool is very essential. Overall, the Sensor together with their outlets as one unit be accommodated in a rear housing part, wherever they are are easily accessible.
  • the bending beam is a radial leg of a support ring for fastening the bending beam in the rear part of the housing, so that the annulus for the penetration of other working elements, such as an angle encoder, is available.
  • This is expediently Counter wheel of such an encoder immediately adjacent to the Bending beam arranged on the motor shaft of the compressed air motor, so that a spatial unit of these receiving elements is guaranteed.
  • the control element is expediently used as Adjustment rod designed to be very simple as a pressure-conducting Connecting element in the output shaft and the motor shaft can be accommodated and since it has a rolling bearing expediently acts on the bending beam, hardly any Is exposed to wear.
  • the one shown in Figure 1 in training as a hand tool Impulse wrench has a handle 1 with a pressure switch 2 with which a not shown in the drawing Tilting valve for the compressed air supply can be operated. Above the handle 1 is inside a housing 3 Compressed air motor 4, which is followed by a pulse unit 5 is. The compressed air supply 6 opens into a compressed air chamber 7 in the housing 3, from where it reaches the air motor. At 9 is a centrifugal switch mounted on a motor shaft 8 referred to the one surrounding the motor shaft 8 Compression spring 10 acts. On that facing away from the shut-off valve 9 At the end sits a sleeve-shaped cover 11 of the pulse unit 5, which is rotatably connected to the motor shaft 8 is. This cover 11 is non-rotatable with an opposite one cylindrical housing 12 connected on a Output shaft 13 of the pulse unit 5 is mounted. The Output shaft 13 ends at a short distance from it axially aligned motor shaft 8.
  • the cover 11 and the housing 12 delimit one between them Cylinder chamber 14 which is eccentric in that of the cover 11 and the housing 12 limited cylinder of the pulse unit 5th is provided.
  • the output shaft 13 passes through this cylinder chamber 14 and is conventionally eccentric in Arranged with respect to the axis of this cylinder chamber 14.
  • Slat 15 radially slidably housed under the Force is exerted by two compression springs 16, which the lamella 15 radially outwards against the cylindrical wall of the housing 12 presses.
  • the output shaft 13 with roller bearings 17 and 18 in the motor housing 3 rotatably, which the cylindrical Sheath of the housing 12 of the pulse unit with formation of an annular gap 19 surrounds.
  • the output shaft 13 At the front end takes the output shaft 13 a not shown here Tool, for example a chuck for screwing tools on.
  • the cylinder chamber 14 is known per se through the lamella 15 Divided into two chambers, not shown, the cylinder chamber 14 being completely filled with pressure medium, is preferably filled with pressure oil.
  • the pulse screwdriver is with a frequency setting device 20 provided by an adjusting screw 21 is formed, which is in a coaxial threaded bore of the output shaft 13 is screwed.
  • the adjusting screw 21 leaves operate easily from the outside.
  • the adjusting screw 21 extends with a thread-free section in a central the output shaft 19 penetrating bore 22 in the also an adjusting rod 23 is received, which is in a bore 24 of the axially aligned motor shaft 8 is mounted.
  • a compression spring 25 arranged at its other end a shoulder of the actuating rod 23 is supported.
  • This bending beam 27 is how best seen in Figure 2, part of an over a pin 29 on the housing part 28 fixed ring 30 and forms a radial leg of this ring 30.
  • a cable harness 33 received in a stuffing box 32 become an electronic switching element 34 leads.
  • One of the transducers takes tensile, the other Pressure loads.
  • the spring 25, which is also opposite another component of the pulse screwdriver firmly supported can be used so that the rod and ball are always connected is held with the bending beam.
  • the end of the adjusting rod 23 facing the pulse screwdriver 5, on which the compression spring 25 is supported, is not about bores shown in fluid connection with the Cylinder chamber 14 so that the cylinder chamber 14 pressure build-up on the adjusting rod during the screwing process 23 is present, which is correspondingly strongly dependent on the pressure the bending beam 27 is pressed, where the at the front end of the Actuating rod 23 pending pressure or that on the bending beam 27 acting force as a bending moment through the strain gauges 31 is added.
  • These pressure-dependent bending moments are given over the line in the wiring harness 33 and via the switching element 34 of an electronic control unit 40 supplied, where the determined bending moment with a predetermined Limit torque for the screw connection compared becomes.
  • Control valve 43 actuated, via which the compressed air supply interrupted via line 44 to the compressed air motor 4 and the impulse wrench is switched off immediately.
  • an angle count is carried out via the angle encoder 35, 37, so that to increase the security of the correct Tightening a screw connection the torque and the Angle of rotation can be used.
  • angles of rotation and torque at the time of shutdown with a a maximum and minimum torque and certain angles of rotation given window are compared, the Circuit a light signal in a specific color or generates a beep when the switch-off time in the window defined in this way.
