Definitions

  • the invention relates to a method for controlling the tightening angle of screwing when tightening by means of a hand-held screwing tool.
  • the invention further relates to a screwing with a turn-off, which allows the most accurate shutdown of the screwing when reaching a predetermined tightening angle.
  • Such a defined biasing force is u.a. with a more or less large deviation. achieved by the fferanzugs Kunststoff "torque controlled”, “rotational angle controlled” or “elongation controlled”.
  • a very accurate method is the rotation angle controlled method. It is used for precise screw connections with stationary screw spindles.
  • the angle of rotation of the output shaft can be determined from a certain threshold torque via an angle measuring device in the screwing. The fact that the screw is firmly mounted and receives the reaction torque that arises when tightening the screw, the measured angle corresponds to the tightening angle of the screw.
  • the invention has for its object to provide an improved method for controlling the tightening angle of fittings, with a predetermined tightening angle can be met more precisely even with hand-held screwdrivers. Furthermore, a suitable screwing tool is to be specified, with which such a method can be carried out.
  • the relative rotation of the screwing tool is measured due to the reaction torque and taken into account as a correction variable in the determination of the rotation angle of the output shaft.
  • the angle of rotation measuring device for measuring the angle of rotation of the output shaft may be, for example, a pulse disc with forked light barrier or a rotary encoder.
  • the torque measuring device may be, for example, a torque sensor with strain gauges.
  • the rotational angle measuring device for measuring the relative rotation of the screwing tool for screwing for example, have an acceleration sensor or a gyroscope.
  • FIG. 1 shows a schematic diagram of a screwing tool according to the invention, with which a screw is tightened by means of a bit.
  • Fig. 1 is to be tightened fitting 12 by tightening a screw 14 on a workpiece 13 to produce a predetermined angle of rotation.
  • a hand-held screwing tool 10 which has an output shaft 16, from which a bit 18 is received for tightening the screw 14.
  • the output shaft 16 is driven by a drive 20 (e.g., electric motor) coupled to the output shaft 16 via a shut-off device 22. Furthermore, a torque measuring device 30, which measures the torque D transmitted by the screwing tool 10, also acts on the output shaft 16.
  • a drive 20 e.g., electric motor
  • a torque measuring device 30 which measures the torque D transmitted by the screwing tool 10 also acts on the output shaft 16.
  • a rotational angle measuring device 24 for example in the form of a pulse disc with forked light barrier provided, by means of the reaching from a predetermined threshold value of the rotational angle ⁇ of the output shaft 16 is detected.
  • the screw 10 has a measuring device 26 for measuring the relative rotation of the screwing tool 10 with respect to the screw 12 and the workpiece 13.
  • This measuring device 26 may be, for example, a measuring device with an acceleration sensor.
