Definitions

  • the invention relates to a device with a screwing with electronic torque limiter according to the preamble of claim 1 and a method for operating the device.
  • a known screwing tool as a power screwdriver has a controllable drive and an integrated torque sensor and rotation angle sensor.
  • strain gauges are applied as a torque sensor for the torque detection on a shaft center part of a planet carrier whose power supply is made inductively contactlessly via a stator coil and a rotor coil.
  • a structure is mounted as a toothed disk ring for rotational position detection on the shaft center part, which is scanned by a non-contact scanning device in the form of an optical sensor.
  • a combination of a torque detection and a rotary position detection is provided for a tracking control here.
  • the screwing tool is turned off after reaching a set pre-torque and after performing a certain rotation angle follow-up path here.
  • the settings of these values can be carried out here directly on a control panel of the screwing tool.
  • a device as a mounting documentation system (alkitronic-MDS) is further known with a portable control device, which is connected for a screwing operation with the screwing tool via a data line.
  • This controller represents an input control documentation unit to which process-specific default data, such as target torque values, parameter inputs, control commands, etc., can be entered via a keyboard.
  • process-specific default data such as target torque values, parameter inputs, control commands, etc.
  • the object of the invention is therefore a generic device with a screwdriver with electronic torque limiter so educate that on the one hand for screwing, especially for complex and difficult screwing tasks by highly qualified professionals is easy to use and on the other hand allows a worker at the place of the screwing a simple worker-friendly operation and control of the screwing on the basis of the expertise of a highly skilled.
  • the input control documentation unit is modular:
  • a module part is a separate from the screwing and separate computer with an installed screwing ( directorysoftware) and a computer keyboard, with a variety of default data, such as naming data for screwing and control data in the tightening program for storage and possibly for pre-calculations can be entered.
  • default data such as naming data for screwing and control data in the tightening program for storage and possibly for pre-calculations can be entered.
  • an engineer as a specialist in an office all required for one or more screwing data, specifications, precalculations, interpretations, etc. can be conveniently entered and executed without local and temporal connection with the actual screwing.
  • An online control of a screwing tool with such a computer on site by an engineer would be very expensive and is not practical at all.
  • the manual control unit can be connected to the computer before a screwdriving operation, whereby a data transfer from the computer-installed screwdriving program into the control unit data memory, in particular for designation data and control data, and optionally for screw-part programs and precalculation results, can be carried out.
  • the manual control unit is for a screwing independently of the computer at the location of the screwing at the local screwdriver for control data specification and / or for its control with a data line via a cable connection or wirelessly connectable or integrated via radio.
  • a cable connection can be made with appropriate plugs easily by a worker without special training.
  • the screwing tool in particular torque values and / or rotational angle values, are transmitted back to the manual control unit via the data line and stored in the control unit data memory assigned to the designation data for evaluation, readout and documentation.
  • the worker thus has to carry out only simple operations, with an analysis and evaluation of the ffervorgangsoire takes place only to the extent that is displayed on the manual control unit, whether the screwing performed exactly with the appropriate specifications was or was faulty.
  • the operator does not have to carry out measures for the documentation of a screwdriving process, since the corresponding data is stored in the control unit data memory for later reading by a computer.
  • the documentation can then be made by printing on paper or on digital media.
  • warning signals can be generated when the screwdriving process is not performed exactly on the control unit display or on separate warning LEDs. Also acoustic warning signals can be delivered via loudspeakers.
  • high-quality screw connections are regularly performed as a combination of a pre-torque and a follow-up path with a certain rotation angle to obtain a target torque.
  • the pre-torque to be set and the post-rotation angle depend on a plurality of factors and parameters, for example the type of screwing, the material, the tolerances, etc.
  • the rotation angle calculation then takes into account the entered gland-specific parameters. If appropriate, a corresponding program part can also be transferred to the manual control unit.
  • the manual control device is a portable independently of the screwing device, which is connectable with this for a screwing with a cable as a data line and optionally for power.
  • the hand control unit and the screwing tool are only by the Connected data line and otherwise handled separately, which is convenient and advantageous for many applications.
  • the power supply of the manual control device should be carried out according to claim 5 via a battery and / or optionally via the cable connection from an electrically operated screwing.
  • this can also be integrated detachably or permanently in the screwing tool, depending on the circumstances.
  • a proven USB connection is proposed for the data transmission between the computer and the hand control device.
  • the device according to the invention is possible with any screwing tool designed for cooperation with a manual control device, which has a controllable electric or pneumatic or hydraulic drive.
  • a hydraulic ratchet screwdriver with a double-acting hydraulic cylinder-piston drive can be used, such as from EP 1 400 313 B1 known.
  • the drive is here connected to a controllable hydraulic pump and the tightening of a screw takes place by the ratchet movement and not by a continuous rotation.
  • the screwing is therefore controlled here including stored, the hydraulic ratchet screw associated torque tables and including calibration and Kontrollh Claus. Since the pressure in the hydraulic ratchet screw acts linearly with the torque, a pressure sensor is used as the torque sensor.
  • Claim 10 also claims a method of operating a device according to any one of claims 1 to 9.
  • a device 1 is shown with a screwdriving tool as a power screwdriver 2 a hand control unit 3 and a separate and separate computer 4 as a laptop.
  • the relevant process-specific, individual specification data in particular a project name, user names, project numbers, bolting parameters, tolerance limits, etc., are entered by a corresponding expert on the computer 4 by means of which the screwing tasks on a project, for example a wind generator with rotor blades and a rotor rotor, are characterized.
  • the hand control unit 3 has an integrated control unit data memory and a control unit display and with respect to the computer keyboard 6 a few function keys 7.
  • the manual control unit 3 is brought in preparation for the screwing in the vicinity of the computer 4 and connected to this via the (dashed line) data line 8 with a USB connection.
  • the (dashed line) data line 8 with a USB connection.
  • the manual control unit is transported to the location of the screwing operation and connected there to the data line 9 with the power screwdriver 2.
  • the power wrench 2 is placed on a screw 11 by a worker 10 with his tool attachment.
  • the naming data, control data, etc. assigned to the current screwing operation are selected and called up, and then the screwing operation is started on the manual control unit 3 or optionally on the power screwdriver 2.
  • the control of the screwing process then takes place via the manual control unit 3, wherein from the power screwdriver 2 current screwing data, such as currently achieved torque and / or current rotation angle are transmitted back, which is symbolized by the double arrow 12.
  • current screwing data such as currently achieved torque and / or current rotation angle are transmitted back, which is symbolized by the double arrow 12.
  • These data are stored in the ECU memory for later documentation.
  • these data are analyzed and it is determined whether a screwdriving process has been carried out exactly according to the specifications. If this has not been done, an optical and audible warning signal is issued on the hand control unit 3.
  • the manual control unit 3 is again separated from the power wrench and transported to the computer 4 and again with this Data line 8 connected.
  • the computer 4 With the computer 4, the stored Verschraubungs stylist can then be read from the control unit data memory (symbolized by the double arrow 13) and provided for documentation for printing on paper or for further digital storage.
