Definitions
- the present invention relates to a torque wrench arrangement with a screwdriver housing, a drive train arranged in the screwdriver housing, which has a drive housing, a motor arranged in the drive housing, in particular an electric motor, and an output shaft that protrudes from the drive housing on its axially front end and the axially front end of which comprises a bit holder for fixing a screw bit or is rotatably ver bindable with such, and a torque measuring device.
- the present invention relates to a method for operating a torque screwdriver arrangement.
- Torque wrench assemblies for tightening and loosening screws are well known. Such torque wrench assemblies are more and more often provided with a torque measuring device for detecting the screw tightening torque.
- EP 2 127 812 A1 discloses a torque wrench arrangement with a screwdriver housing and a drive train arranged in the screwdriver housing.
- the drive train comprises a drive housing, an electric motor arranged in the drive housing with an output shaft, a transmission also arranged in the drive housing and connected to the electric motor via its output shaft, and an output shaft of the transmission which protrudes from the drive housing on its axially front end and the axially front end of which via a coupling mechanism nism with a bit holder for fixing a screw bit is rotatably connectable.
- the torque wrench arrangement of EP 2 127 812 A1 comprises a torque measuring device which is arranged in the axial direction of the drive train between the electric motor and the transmission. Specifically, strain gauges are applied to the outside of the drive housing in the area of the drive housing that surrounds the output shaft of the electric motor, by means of which the screw tightening torque can be detected. As soon as the recorded screw tightening torque reaches a predetermined value, the electric motor can be stopped accordingly. In addition, the area of the drive housing that surrounds the electric motor is firmly connected to the screwdriver housing. In this way, the reaction torque exerted on the drive housing is supported over a large area during operation of the torque wrench arrangement. With the torque wrench arrangement of EP 2 127 812 A1, only a very imprecise detection of the output and / or reaction torque is possible.
- the present invention is based on the object of providing a torque wrench arrangement of the type mentioned, which enables the most precise possible detection of the output torque of the output shaft and is also inexpensive to manufacture and operate.
- a torque wrench arrangement of the type mentioned at the outset in that a support arrangement is provided at exactly one support point, via which the reaction torque exerted on the drive housing during operation of the torque wrench arrangement is supported on the screwdriver housing, and the drive housing can otherwise be rotated in the screwdriver housing is provided or stored, and that the torque measuring device, which is provided in particular on the support arrangement, designed and / or set up to detect the output torque of the output shaft in the form of the supported reaction torque on the support arrangement.
- the output torque of the output shaft is detected in the form of the supported reaction torque on the support arrangement.
- the invention is therefore based on the idea of supporting a reaction torque exerted on the drive housing at exactly one support point between the drive housing and the screwdriver housing via a support arrangement and otherwise providing the drive housing in the screwdriver housing so that it can rotate about a longitudinal axis of the drive train.
- the output torque occurring on the output shaft is transmitted from the output shaft via a drive mechanism and the drive housing of the drive train to the support arrangement, where it can be detected as a reaction torque.
- the output torque is converted into a measurable rotational deflection of the support arrangement.
- a detection of the reaction torque is convenient, since a measurement on the rotating output shaft, which is often associated with problems, can be dispensed with.
- the torque measuring device can be connected to the support arrangement or attached thereto.
- the support arrangement can include at least part of the torque measuring device.

- the support arrangement is axially between the two arranged at the front end of the drive housing, preferably the axially front end face of the drive housing, and the screwdriver housing. In this case, the support and detection of the reaction torque takes place relatively close to the output shaft, which contributes to the most precise possible recording of the output torque.
- the support arrangement can be connected to the screwdriver housing via an inter mediate element.
- the intermediate element is preferably releasably connected to the support arrangement and / or the screwdriver housing, in particular screwed.
- the support arrangement can be connected to screwdriver housings with different geometries. As is known, screw connections have the advantage that they are detachable.

In the third embodiment, this consists of two separate elements, which is why the drive housing 7 is not connected to the screwdriver housing 4 via the support arrangement 13. More precisely, the support arrangement 13 has a support element 40 on the drive housing side and a support element 41 on the screwdriver housing side, the end faces 43, 46 of which bear against one another.
- the support element 40 on the drive housing side is designed as an annular fastening flange 22 with four through bores 23 as drive housing connecting means and a central bore 42.
- the support element 40 on the drive housing side is provided with a recess 44 on its end face 43 facing the support element 41 on the screwdriver housing side.
- the screwdriver housing-side support element 41 is designed as an annular plate 45, on whose end face 46 facing the drive housing-side support element 40, a protrusion 47 corresponding to the recess 44 and protruding into it is arranged.
- On the opposite end face 48 of the ring-shaped plate 45 is a sleeve-like extension 49 which is arranged coaxially to a central bore 50 of the annular plate 45.
- the central bore 50 of the ring-shaped plate 45, the extension 49 and the central bore 42 of the fastening flange 22 form the central through-opening 27 of the support arrangement 13.
- the sleeve-like extension 49 is provided with an external thread section 51 as a screwdriver housing connecting means via which the screwdriver housing-side from the support element 41 with the correspondingly designed internal thread deabêt 32 at the axially rear end of the coupling device housing 19 is in threaded engagement.
- the third embodiment between two opposite sides, facing in the circumferential direction of the support arrangement 13
- a gap 53 is formed.
- the arrangement is such that the reaction torque is supported in the circumferential direction of the support arrangement 13 between the side surfaces 52.
- piezo elements 16d are provided instead of strain gauges 16a or instead of a magnet 16b and a Hall sensor 16c. More precisely, the two piezo elements 16d are each on a side surface 52 of a gap belonging to the support element 40 on the drive housing side
- Figures 13 and 14 show schematic partial sectional views of the torque wrench assembly 1 according to the first, second and third embodiments. These are only intended to clarify the position of the support point 14.
- the support point 14 is at the axially front end of the drive housing 7.
- the support arrangement 13 is arranged between the axially front end face of the drive housing 7 and the screwdriver housing 4.
- FIG. 15 shows a schematic partial sectional view of a torque screwdriver arrangement 1 according to a fourth embodiment of the present invention.
- the fourth embodiment differs from the first, second and third embodiments in that the support point 14 is located at the axially rearward end of the drive housing 7.
- the support arrangement 13, via which the reaction torque exerted on the drive housing 7 is supported at the support point 14 on the screwdriver housing 4, is, for example, one of the in connection with the First three embodiments described support arrangements 13.
- the drive housing 7 is accordingly rotatably mounted in the screwdriver housing 4 at its axially front end.
- the torque wrench arrangement 1 according to the invention according to the four embodiments described above can be operated according to the method explained below.
- a user can first set a desired target torque via the user interface 34 by entering the desired target torque or by selecting from several predefined selection options stored in the memory 33.
- the screwdriver 2 is pressed by the user with a screw bit fixed in the bit holder 12 of the bit holder 11 against a screw to be turned and the screwdriver 2 is activated either automatically when a desired contact pressure is reached or manually by the user, i.e. the motor 8 is switched on .
- the screw bit nor the screw are shown in the figures.
- the output torque of the output shaft 10 causes a reaction torque exerted on the drive housing 7, which is supported by the support arrangement 13 at the support point between the drive housing 7 and the screwdriver housing 4.
- the output torque of the output shaft 10 is recorded in the form of the supported reaction torque on the support arrangement 13.
- strain gauges 16a are used, the torque is measured by measuring a deformation of the torsionally elastic support arrangement 13, in particular the connecting webs 28 or the fastening flange 22.
- the second embodiment of the invention i.e.
- the torque is detected by measuring a displacement and / or rotation of the magnet 16b and the fall sensor 16c in the circumferential direction of the torsionally flexible support arrangement 13 relative to one another in the event of a rotatory deflection of the torsionally flexible brace arrangement 13, i.e. when the sleeve 26 rotates against one another and of the fastening flange 22.
- the third embodiment of the invention i.e.
- the torque is detected by reducing the width of a gap 53 when the two support elements are rotated against each other 40, 41 a pressure is exerted on the Pizeo element 16d arranged in the gap 53, which pressure can be detected as an electrical signal.
- the output torque can be recorded much more precisely via the reaction torque compared with previously known torque wrench arrangements. If necessary, the measurement can also be compared with a recorded motor current of the motor 8.
- the detected reaction torque is then compared with the preset desired target torque by means of the control electronics 3. As soon as the setpoint torque is reached or exceeded, the control electronics 3 cause the motor 8 to be switched off automatically. In this way, damage to a screw connection produced by means of the torque wrench device 1 can be avoided. If necessary, the torque wrench arrangement 1 can be calibrated in particular via the control electronics 3. A certified measuring method is used here, which is compared with the recorded measured values from the screwdriver 2. The recorded measured values of the screwdriver 2 are then adapted depending on the amount of deviation in the measured values.
