  • Fig. 1 shows a driving device 10 for driving a fastening element, for example a nail or bolt, into a surface in a side view.
  • the driving-in device 10 has an energy transmission element (not shown) for transmitting energy to the fastening element and a housing 20 in which the energy transmission element and a drive device (also not shown) for conveying the energy transmission element are accommodated.
  • the driving-in device 10 also has a handle 30, a magazine 40 and a bridge 50 connecting the handle 30 to the magazine 40.
  • a scaffold hook 60 for suspending the driving device 10 on a scaffold or the like and an electrical energy store designed as an electrical accumulator 590 are fastened to the bridge 50.
  • a trigger 34 and a handle sensor designed as a hand switch 35 are arranged on the handle 30.
  • the driving-in device 10 has a guide channel 700 for guiding the fastening element and a pressing device 750 for recognizing a distance of the driving-in device 10 from a substrate (not shown). Alignment of the driving device perpendicular to a surface is supported by an alignment aid 45.
  • Fig. 2 shows the driving-in device 10 with the housing 20 open.
  • the drive device 70 for conveying one which is hidden in the drawing Energy transmission element added.
  • the drive device 70 comprises an electric motor (not shown) for converting electrical energy from the rechargeable battery 590 into rotational energy, a torque transmission device comprising a transmission 400 for transmitting a torque of the electric motor to a motion converter designed as a spindle drive 300, and a force transmission device comprising a roller train 260 for transmitting a force from the motion converter to a mechanical energy store designed as a spring 200 and for transmitting a force from the spring 200 to the energy transmission element.
  • Fig. 3 shows a longitudinal section of the driving-in device 10 after a fastening element has been driven forward, that is to the left in the drawing, into an underground with the aid of the energy transmission element designed as a piston 100.
  • the piston is in its setting position.
  • the front spring element 210 and the rear spring element 220 are in the relaxed state, in which they actually still have a certain residual tension.
  • the front roll holder 281 is in its foremost position in the operation and the rear roll holder 282 is in its rearmost position in the operation.
  • the spindle nut 320 is located at the front end of the spindle 310. Because of the spring elements 210, 220, which may be relaxed to a residual tension, the band 270 is essentially load-free.
  • control device 500 As soon as the control device 500 has recognized by means of a sensor that the piston 100 is in its setting position, the control device 500 initiates a return process in which the piston 100 is moved into its starting position.
  • a motor rotates the spindle 310 in a first direction of rotation via the gear 400, so that the spindle nut 320 which is secured against rotation is moved to the rear.
  • the return rods 199 engage in a backwood pin of the piston 100 and thus also convey the piston 100 to the rear.
  • the piston 100 takes the band 270 with it, which means that the spring elements 210, 220 are not tensioned, since the spindle nut 320 also takes the band 270 to the rear and thereby releases just as much band length via the rear rollers 292 as the piston between the front rollers 291 moves in.
  • the belt 270 therefore remains essentially load-free during the return process.
  • Fig. 4 shows a longitudinal section of the driving device 10 after the return process.
  • the piston 100 is in its initial position and is coupled with its coupling plug part 110 in the coupling device 150.
  • the front spring element 210 and the rear spring element 220 are still in their respective relaxed state, the front roller holder 281 is in its foremost position and the rear roller holder 282 is in its rearmost position.
  • the spindle nut 320 is located at the rear end of the spindle 310. Because of the relaxed spring elements 210, 220, the band 270 is still essentially load-free.
  • the control device 500 initiates a tensioning process in which the spring elements 210, 220 are tensioned.
  • the motor rotates the spindle 310 via the gear 400 in a second direction of rotation opposite to the first direction of rotation, so that the spindle nut 320 secured against rotation is moved forward.
  • the coupling device 150 holds the coupling plug part 110 of the piston 100 in place, so that the band length which is drawn in by the spindle nut 320 between the rear rollers 292 cannot be released by the piston.
  • the roller holders 281, 282 are therefore moved towards one another and the spring elements 210, 220 are tensioned.
  • Fig. 5 shows a longitudinal section of the driving device 10 after the tensioning process.
  • the piston 100 is still in its initial position and is coupled with its coupling plug part 110 in the coupling device 150.
  • the front spring element 210 and the rear spring element 220 are tensioned, the front roller holder 281 is in its rearmost position and the rear roller holder 282 is in its forwardmost position.
  • the spindle nut 320 is located at the front end of the spindle 310.
  • the band 270 deflects the clamping force of the spring elements 210, 220 on the rollers 291, 292 and transmits the clamping force to the piston 100, which is held against a holding force by the coupling device 150.
  • the driving device 10 is now ready for a driving process. As soon as a user pulls the trigger 34, the coupling device 150 releases the piston 100, which then transfers the clamping energy of the spring elements 210, 220 to a fastening element and drives the fastening element into the ground.
  • Fig. 6 shows a longitudinal section of the coupling device 150 with the piston 100 coupled.
  • the piston 100 has a coupling plug part 110 with coupling recesses into which a plurality of locking elements 160 of the coupling device 150 can snap.
  • the piston 100 has an actuating element designed as a shoulder 125, as well as a band feedthrough 130 and a convex conical section 135.
  • the locking elements, in particular designed as balls 160, and / or the inner sleeve 170 are made of hardened steel.
  • the parts of the coupling device which are moved relative to one another, in particular the locking elements and / or the inner sleeve, are preferably provided with a lubricant or lubricant.
  • the locking elements and / or the inner sleeve are made of ceramic.
  • the piston 100 comprises a shaft 140 and a head 142, the shaft 140 and the head 142 preferably being soldered to one another.
  • a positive connection in the form of a shoulder 144 prevents the shaft 140 from slipping out of the head 142 in the event of a break in the soldered connection 146.
  • the piston is formed in one piece.
  • Coupling of the piston 100 into the coupling device 150 begins in an unlocked state of the coupling device 150, in which the outer sleeve 180 acted upon by the return spring 190 allows the balls 160 to be received in the recesses 182.
  • the piston 100 can therefore displace the balls 160 to the outside when the piston 100 is inserted into the inner sleeve 170. With the help of the shoulder 125, the piston 100 then displaces the outer sleeve 180 against the force of the return spring 190 and closes the coupling device 150. As soon as the pawl 800 is engaged with the coupling pin 195, the coupling device 150 is held in the locked state.
  • one or more entrainment elements of an energy transmission device each have an actuating element which displaces the outer sleeve when the piston is inserted into the coupling device.
  • the driving elements serve to convey the piston to the coupling device, so that the driving elements are moved with the piston.
  • the piston is coupled from the spindle nut 320 into the clutch device by means of the return rods 199. How far the piston 100 is moved into the Kulunsvorrichtun 150 depends on a stop position Spindle nut 320. Since the stop position of the spindle nut 320 can shift over time, for example due to temperature fluctuations and / or wear, there is a risk that the piston 100 is not always securely coupled into the coupling device 150. In order to counter this danger, the piston 100 is inserted into the coupling device to such an extent that it covers an additional distance after the coupling. Sufficient space must be provided within the coupling device 150 for this additional path. In order to be able to choose the additional travel of the piston 100 as small as possible, the recurring return process is controlled using a method described below.
  • the control device 500 controls the stopping of the spindle nut 320 forming a control element in the FIG Fig. 4 Stop position shown by means of a control parameter, for example an electrical voltage, a current, a speed and / or a switch-off time of the motor or the number of revolutions or commutations of the motor until the motor that drives the spindle 310 is switched off.
  • a control parameter for example an electrical voltage, a current, a speed and / or a switch-off time of the motor or the number of revolutions or commutations of the motor until the motor that drives the spindle 310 is switched off.
  • the driving-in device has a clutch sensor 198, which transmits a signal to the control device 500 as soon as the piston 100 is engaged in the clutch device 150 and / or the clutch device 150 is closed .
  • the control device 500 then forms a difference between the actual stop position and a target stop position of the spindle nut 320, for example by counting revolutions / commutations of the motor after receiving the signal transmitted by the clutch sensor 198 and stopping the motor or the spindle nut 320. If the difference formed exceeds a predetermined target value, the control device 500 adjusts the control parameter for a subsequent return process. This makes it possible to use a small coupling device 150.
