Definitions

  • the invention relates to a driving tool with fastening means according to the preamble of claim 1.
  • the centering elements of the centering device for the screws are designed as holding jaws, which are arranged pivotably on a bearing body and have contact surfaces for holding the screws, which are perpendicular or inclined to the pivoting plane.
  • Such centering devices are also known for driving tools for nails, pens, etc., which are generally referred to below as "fastening means”.
  • the centering elements can yield when a lateral force acts on the fastening means. This means that the fastener is not securely held when screwing in or driving in and may penetrate the workpiece at an angle. This is particularly disadvantageous when assembling furniture.
  • the object of the present invention is therefore to create a driving tool of the type mentioned at the outset with a centering device for the fastening means which securely holds and guides it during the driving process.
  • the centering elements only move when e.g. in the case of the screw, the head, which is larger than the shaft, presses it apart or when the driving plunger in a driving tool for nails pivots the centering elements.
  • the invention can be used particularly advantageously in screwing devices in which the motor housing with the motor-driven screw-in blade is arranged so as to be displaceable against a bearing body for the centering elements against the action of a spring.
  • This bearing body can also be designed as a foot.
  • the contact surfaces of the centering elements are provided with ribs which project beyond the contact surfaces and extend essentially transversely to the driving direction and which engage in the thread of the screw when screwing in.
  • the screw pulls the bearing body against the spring between the bearing body and the motor housing, so that the operator does not have the force to compress the spring.
  • the bearing body is fixed to the motor housing, i.e. e.g. connected to a cylinder-piston unit and only the impact ram moves against a foot.
  • the invention is applicable to both portable and stationary driving tools.
  • a centering device 9 serves to hold the fastening means 2 before and during the driving-in process. It consists of three identical centering elements 10, which are mounted on the bearing body 3 in a radially pivotable manner.
  • the bearing body 3 is provided with a retaining ring 11 which, as also shown in FIG. 2, has bearing blocks 12.
  • These Bearing blocks 12 are provided with threaded bores 13 into which bolts 14 are screwed, which have journal pins 15 for the centering elements 10 at their protruding end.
  • These centering elements 10 are pressed in the direction of the fastening means 2 by an elastic ring spring 16.
  • the centering element 10 extends from the journal 15 with a leg 17 in the driving-in direction, and has at its free end a contact jaw 18 arranged perpendicular to the leg 17. This is provided with a contact surface 19 directed against the fastening means 2, which runs perpendicular to the axis 20-20 of the journal 15.
  • the contact surface 19 extends parallel to the plane of movement of the centering element 10 and lateral forces acting on the fastening means 2 are absorbed by the centering element 10 without this yielding. Only the enlarged head 8 of the fastening means 2 causes the centering elements 10 to pivot.
  • a run-on slope 21 on the contact jaws 18 serves to initiate the pivoting movement of the centering element 10 through the head 8.
  • the contact jaw 18 is further provided with an insertion slope 22 which facilitates the insertion of the fastening means 2 between the contact jaws 18. (Fig.2)
  • the threaded bores 13 for the screw bolts 14 are arranged on the retaining ring 11 in the form of an equilateral triangle.
  • the bolts 14 have slots 23 so that they can be adjusted by means of a screwdriver so that the centering elements 10 can be adapted to different diameters of the shafts 7 of the fastening elements 2 perpendicular to their plane of movement.
  • FIG 3 and 4 show a further embodiment of the invention, wherein the bearing body 24 is designed as a foot with which the driving tool on the Workpiece 5 can be placed.
  • a screw-in blade 6 is again used to screw in fasteners 2.
  • Slots 25 are provided in the bearing body 24, in which the centering elements 26 are mounted so as to be radially displaceable. They are resiliently pressed inwards by an annular spring 27. The contact surface 28 of the centering element 26 also runs parallel to the plane of movement here, so that the centering elements 26 cannot escape due to lateral forces on the fastening means 2.
  • FIG. 5 to 7 show a further embodiment of the invention, wherein a bearing body 29 is slidably mounted on the motor housing 31 against the action of a spring 30.
  • a drivable screw-in blade 6 connected to the motor housing 31 serves for screwing in a first screw 32 ′, with which a plasterboard plate 33 is to be fastened to a workpiece 34 made of wood or steel underneath.
  • the screw 32 ' is fastened with further screws 32 in a known manner to a connecting belt 35 made of plastic and can be loosened from this connecting belt when screwed in.
  • two centering elements 36 and 37 are provided, which are pivotably mounted on the bearing body 29 against the action of leg springs 38, the pivot axes 39-39 and 40-40 being perpendicular to one another.
  • the contact jaws 41 of the centering element 36 again have a contact surface 42 which is parallel to the pivoting plane (see FIG. 7).
  • the contact jaw 43 has ribs 45 which project beyond the contact surfaces 44 and extend essentially transversely to the driving direction and which engage in the thread 46 when the screw 32 'is screwed in.
  • the rotating screw is forced a feed movement, the bearing body 29 being drawn against the action of the spring 30 against the motor housing 31 and the head 47 of the screw 32 'releasing the latter after the connecting belt 35 has been reached.
  • the contact jaws 41 are provided with a pocket 50 into which the contact jaws 43 engage in the rest position.
  • the run-up slope 48 of the system jaws 41 is, seen in the screwing-in direction, arranged in front of the run-up slope 49 of the system jaws 43.
  • the contact jaws 41 are pivoted outward by the screw head 47 and thereby release the contact jaws 43, which is then also pivoted outward.
  • the screw 32 ' is securely guided by the contact jaws 41 and 43 until the solid workpiece 34 made of wood or steel is reached.
