Definitions

  • the invention relates to a device for driving fasteners in a driving direction in a workpiece, such as a setting tool for setting fasteners such as nails, bolts, rivets, screws or anchors.
  • Driving-in devices are known from the prior art, each comprising a housing and a pressure sensor, the pressure sensor being able to be pressed against a workpiece in a driving-in direction and thereby being displaceable relative to the housing in the opposite direction to the driving-in direction.
  • Support elements are known which support the respective workpiece against the driving direction.
  • a device for driving fasteners in a driving direction into a workpiece comprising a housing, a pressure sensor which can be pressed against the workpiece in the driving direction and thereby displaceable relative to the housing against the driving direction, and a support element which supports the workpiece against the driving direction while a fastener is driven into the workpiece.
  • the support element can be displaced transversely, preferably perpendicularly, to the driving direction relative to the pressing sensor, while the pressing sensor is displaced relative to the housing against the driving direction.
  • An advantageous embodiment is characterized in that the device comprises a drive-in element and a drive accommodated in the housing, which drives the drive-in element onto a fastening element in order to drive the fastening element into the workpiece.
  • a further advantageous embodiment is characterized in that the pressure sensor can be displaced relative to the housing against the driving direction up to a pressing position, the pressing sensor releasing a driving process when the pressing sensor is in the pressing position and blocking the driving process when the pressing sensor is located is outside the pressing position.
  • a further advantageous embodiment is characterized in that the pressure sensor has a guide channel in which a fastening element is guided while the fastening element is being driven into the workpiece.
  • a further advantageous embodiment is characterized in that the support element engages behind the workpiece when the pressure sensor is pressed onto the workpiece.
  • a further advantageous embodiment is characterized in that the support element has a projection which protrudes counter to the driving-in direction and which engages in a recess on the workpiece.
  • a further advantageous embodiment is characterized in that the support element can be displaced linearly transversely to the driving direction, while the pressure sensor is displaced relative to the housing against the driving direction.
  • a further advantageous embodiment is characterized in that the support element can be pivoted transversely to the driving direction about a pivot axis which is preferably oriented perpendicular to the driving direction, while the pressure sensor is displaced relative to the housing against the driving direction.
  • the fastening elements are preferably driven into the workpiece along a driving axis, the pivot axis intersecting the driving axis.
  • the support element likewise preferably comprises a swivel arm which is mounted on the housing so as to be rotatable about the swivel axis.
  • a further advantageous embodiment is characterized in that the support element has a deflecting surface inclined to the driving-in direction, which abuts the workpiece when the driving-in device is moved towards the workpiece, and thereby displaces the supporting element transversely to the driving-in direction. This makes it possible to automatically deflect the support element transversely to the driving direction during a pressing movement against the workpiece.
  • a further advantageous embodiment is characterized in that the support element has an actuating element for manual displacement of the support element transversely to the driving direction. This further simplifies the entire driving process.
  • a device 1 designed as a bolt-driving tool for driving in fastening elements 2 along a driving-in axis 14 in a driving-in direction 3 into a workpiece 4 is shown.
  • the fastening elements 2 are designed as nails, in the case of exemplary embodiments that are not shown, for example as bolts, pins, clamps or screws.
  • the device 1 comprises a drive-in element 5, for example in the form of a setting piston or screw bit, and a drive 7, shown only schematically and accommodated in a housing 6, which drives the drive-in element 5 onto a respective fastening element 2 in order to drive the fastening element 2 into the workpiece 4.
  • the drive 7 comprises, for example, a gas or powder-operated combustion drive, a compressed air drive or a spring, flywheel or electrodynamic electric drive, in particular with an electric motor and an electric battery.
  • the device 1 further comprises a pressure sensor 8 which can be pressed against the workpiece 4 in the driving-in direction 3 and thus relative to the housing 6 against the driving-in direction 3 up to one in the direction Fig. 1 and 4th shown pressing position is displaceable.
  • the pressing sensor 8 In the pressing position, the pressing sensor 8 enables the device to be driven in, while outside the pressing position the pressing sensor 8 blocks the driving in process.
  • the pressure sensor 8 has a guide channel 9, in which a fastening element 2 is guided while it is being driven into the workpiece 4.
  • the device has a guide channel which is separate from the pressure sensor, the pressure sensor then preferably being arranged along the guide channel in the driving-in direction.
  • the workpiece 4 is designed as a connecting sleeve for elongated elements such as pipes or rods, for example reinforcement rods.
  • the workpiece 4 and / or the elements to be connected are preferably made of a metal such as iron or an alloy such as steel.
  • the fastening elements are driven tangentially into a gap between an inside of the workpiece 4 and an outside of the elongated elements in order to connect the elongated elements to the workpiece 4 in a frictional and / or form-fitting manner.
  • the fastening elements 2 are preassembled on the workpiece 4, for example by being inserted into prefabricated passages such as bores, preferably by means of a press fit.
  • the fastening elements are fed to the guide channel individually or in a magazine.
  • the device preferably has a magazine which opens into the guide channel.
  • the device 1 comprises a support element 10, which supports the workpiece 4 against the driving direction 3, while a fastening element 2 is driven into the workpiece 4. This enables the device 1 to be pressed securely onto the workpiece 4.
  • the support element 10 advantageously engages behind the workpiece 4 in the pressing position, that is to say when the pressing sensor 8 is pressed against the workpiece 4. For a secure support of the workpiece 4 by the support element 10, this has Support element 10 has a protrusion 11 protruding counter to the driving-in direction 3, which engages in a recess 12 in the form of a groove on the workpiece 4.
  • the support element 10 can be pivoted relative to the pressure sensor 8 perpendicular to the drive-in direction 3 about a pivot axis 13 oriented perpendicular to the drive-in direction 3 and intersecting the drive-in axis 14, while the pressure sensor 8 is displaced relative to the housing 6 against the drive-in direction 3.
  • the support element 10 comprises two swivel arms 15, which are each mounted on the housing 6 by means of a pivot 16 about the swivel axis 13.
  • the support element 10 has a deflecting surface 17 inclined to the driving-in direction 3, through which the driving-in axis 14 runs, so that the deflecting surface 17 abuts the workpiece 4 and / or the preassembled fastening elements 2 when the device in the driving-in direction 3 on the workpiece 4 is moved to. Due to the inclination of the deflecting surface 17 to the driving-in direction 3, the support element 10 is transverse to the driving-in direction 3 (in Fig. 3 upward) when the deflecting surface 17 abuts the workpiece 4. As a result, the support element 10 is automatically pivoted out of the driving-in axis 14 transversely to the driving-in direction 3 during a pressing movement against the workpiece 4.
  • the projection 11 can move back into the setting axis 14, so that the support element 10 engages behind the workpiece 4 while the device 1 is pressed onto the workpiece 4.
  • This is supported by two return springs 18, which are each mounted between a swivel arm 15 and the housing 6 in order to support the element 10 in the in the 1, 2 and 4th shown position, in which the driving axis 14 extends through the projection 11, preload.
  • the swivel arms 15 each have a damping element 19, on each of which a return spring 18 is mounted.
  • the support element can be displaced linearly transversely to the driving direction, while the pressure sensor is displaced relative to the housing against the driving direction.
  • the support element 10 comprises an actuating element 20 for manually displacing the support element 10 transversely to the driving-in direction 3, with which the supporting element 10 can be released again from the workpiece 4, for example after a driving-in process has taken place.
