Definitions

  • the invention relates to a fastener held in a magazine strip for a setting device, the magazine strip being movable further before or after each setting process, and a feed lock which engages in the feed channel for the magazine strip and is releasable and reusable after each setting process is provided. wherein a drive wheel is provided which engages in a feed channel for the magazine strip and can be brought into operative connection therewith.
  • Some versions of a feed lock have also become known, which are intended to ensure that the magazine strip can be fixed in the respective setting position, but these known designs are of quite complicated construction and in some cases even are designed as a unit with the feed device, so that this results in a slower feed given is.
  • a feed device for a magazine strip is also known (US Pat. No. 4,139,036), in which a drive wheel which can be rotated by hand engages in a perforation provided on a longitudinal side region of the magazine strip. Perforation is also provided on the opposite side longitudinal boundary of the magazine strip, and a spring held on the feed device can snap into it as a feed lock. After each setting process, the magazine strip must be turned further by hand, this feed must be slow so that the feed lock does not simply spring over the next opening of the lateral perforation.
  • the present invention has therefore set itself the task of creating a simple and exact feed possibility and a simple feed lock for the magazine strip in order to bring this and thus the fasteners arranged therein quickly and reliably into the following setting position.
  • the drive wheel can be connected directly or indirectly via a friction clutch arranged in a screwdriver shaft to the rotary drive of the setting tool, and a feed lock designed as a pivotably mounted lever which is held in the locked locking position and acts as a stop for locking cams projecting on the magazine strip Feed channel for the magazine strip engages and its pivoting causes the screwdriver shaft.
  • the measures according to the invention have also made it possible to guide the feed of the magazine strip in a very simple manner from the rotary drive, since a friction clutch is interposed, so that the drive wheel and thus the magazine strip can stop as soon as possible regardless of the further rotary movement of the screw shaft Magazine strip is held by the feed lock.
  • Such an arrangement according to the invention is also practically maintenance-free and also ... grown even rough construction site operation, since no protruding, filigree transport levers are required.
  • the device is described with the aid of a setting tool which is used to screw in screws, preferably self-drilling and thread-cutting screws.
  • a setting tool which is used to screw in screws, preferably self-drilling and thread-cutting screws.
  • Such a device is equally suitable for setting differently designed screws, self-drilling rivets, bolts or the like.
  • the device essentially consists of the setting tool 1 and the setting tool drive 2, the setting device 1 being secured against rotation relative to the setting device drive 2.
  • a screwdriver shaft 3, which is mounted in the setting tool 1, is coupled to the setting tool drive 2.
  • a snap-in coupling 4 is then provided directly on the screwdriver shaft 3, so that the screw nut 5 can grip the head 6 of a screw 7 without any particular torque, the clutch 4 only engaging and thus engaging when the screwdriver shaft 3 is depressed further the rotary drive of the setting tool drive 2 has a full effect on the screw 7.
  • a normal drilling machine can be used as setting tool drive 2.
  • a snap-in coupling is generally integrated in the setting tool drive 2, the screwing shaft 3 executing a rotary movement only when the snap-in coupling is engaged in the setting tool drive 2.
  • the helical spring 59 acts on the snap-in coupling which may be arranged in the setting tool drive 2, the force of the spring 49 being greater than the spring provided in the snap-in coupling integrated in the setting tool drive 2, so that the snap-in coupling integrated in the setting tool drive 2 is practically always closed.
  • the screwdriver shaft 3 carries out a constant rotary movement as soon as the setting tool drive 2 is started up.
  • a rotary drive is maintained as is required for the transport of the magazine strip 18 by a drive wheel 20, which will be explained in more detail later.
  • a clamping part 9 is fastened to a cylindrical extension 8 of the setting tool drive 2, which also carries a guide rod 10, the free end of which engages in an indentation in a projection 11 of the setting device 1. During the entire screwing operation, the shoulder 11 can thus be displaced along the guide rod 10, and thus the setting tool 1 is secured against rotation relative to the setting tool drive 2.
  • An adjustment screw 12 is also provided on the setting tool 1, with which the screwing depth can be determined.
  • the lower end collar 14 of the coupling 4 comes to a stop depending on the setting height of the adjusting screw 12 on the upper head 13 of this adjusting screw 12, so that the screwing process is ended because the coupling 4 disengages shortly after contacting the head 13 and thus the screw nut 5 is no longer connected to the setting tool drive 2.
  • a groove 60 is provided behind the head 13 of the adjusting screw 12, an arcuate recess being present in the head 13 itself. There is thereby the possibility that the end collar 14 of the coupling 4 is pressed down over the head 13 of the adjusting screw 12, the collar 14 being fixed in the groove 60 after turning the head 13 and thus the adjusting screw 12.
  • the screw nut of the screwdriver shaft 3 is fixed in a freely accessible manner at the foremost region of the housing 17, so that any removal of screws, a replacement of the screw nut or also an individual screw connection with manual insertion of the screw into the nut 5 can take place.
  • a coupling corresponding to the coupling 4 according to FIG. 1 is integrated in the setting tool drive 2, so that the screwdriver shaft 3 is connected directly to the setting device drive 2.
  • a guide sleeve 15 is arranged on a corresponding clamping part 9, in which a guide rod 16 fastened to the setting tool 1 is guided. This measure also ensures that the setting tool 1 is prevented from rotating relative to the setting device drive 2.
  • an adjusting screw 12 is provided, which is adjustable at different heights to limit the screwing depth.
  • the setting tool 1 is essentially designed as a housing 17, in which the device for feeding a magazine strip 18 is accommodated.
  • a supply channel 19 is arranged in this housing, which leads continuously through the housing and thus serves for the passage of the magazine strip 18.
  • On the housing 17 is also an on drive wheel 10 mounted in the form of a gear which engages in the magazine strip 18 and is connected to the rotary drive of the setting device.
  • a feed lock 21 also engages in the feed channel 19, which can be released and reinserted after each setting operation.
  • the drive wheel 20 is connected via an angular gear with the interposition of a friction clutch to the screwdriver shaft 3, so that the rotary movement of the screwdriver shaft 3 can be used directly for further transport of the magazine strip 18.
  • the axis 22 of the drive wheel 20 is oriented perpendicular to the axis 23 of the screwdriver shaft 3, a crown wheel 24 seated on the screwdriver shaft 3 advantageously being provided for the transmission of rotation.
  • This crown wheel 24 is arranged in a sliding fit on the screwdriver shaft 3, and is frictionally supported on the screwdriver shaft 3 via resilient sections. This creates a very simple possibility of a friction clutch, so that the rotary movement of the screwdriver shaft 3 can be used to drive the drive wheel 20 and thus to advance the magazine strip 18.
  • this frictional engagement can be accomplished very simply in that the through bore of the crown wheel 24 has one or more axially parallel grooves 25, in which leaf springs 26 are embedded, the bulge of which is resiliently supported on the surface of the screwdriver shaft 3.
  • leaf springs 26 can be held captively on the crown wheel 24 by their upper section bent over the upper end of the crown wheel 24.
  • the crown gear 24 is secured against displacement in the axial direction, on the one hand downward by the engagement of the toothing in the toothing of the drive wheel 20 and on the other hand by the stop of a sleeve 50. It is thereby always a despite the forward and backward movement of the screwdriver shaft 3 secure engagement of the mutual toothing of the crown wheel 24 and the drive wheel 20 is ensured.
  • the drive wheel 20 is mounted on the inner wall of the housing 17 on a bolt 27 and engages with the region facing away from the crown wheel 24 into the feed channel 19 of the magazine strip 18. If the drive wheel 20 and thus also the crown wheel 24 are designed as gear wheels, a special embodiment of a magazine strip 18 is used which has continuous toothing 28 on at least one side edge region. A secure engagement between drive wheel 20 and magazine strip 18 is thereby ensured.
  • the drive wheel 10 would also be conceivable to design the drive wheel 10 as a friction wheel, it also being possible to transmit the force from the crown wheel 24 via a mutual contact surface. In such a case, the drive wheel 20 would have to bear against the magazine strip 18 with a corresponding contact pressure.
  • the drive wheel 20 it would of course also be possible for the drive wheel 20 to be mounted with an axis aligned parallel to the axis of rotation 23 of the screwdriver shaft 3, in which case a corresponding toothing would have to be provided towards the side region of the magazine strip 18.
  • the feed lock 21 essentially consists of a pivotably mounted lever 29 which is held in a locked position and a locking part 30 held thereon.
  • the locking part 30 engages in the feed channel 19 for the magazine strip 18 and serves as a stop for locking cams 31 projecting on the magazine strip.
  • the lever 29 has, at the end facing away from the pivot axis (bolt 32), an extension 33 which engages in the range of motion of the screwdriver shaft 3, so that the lever 29 together with the locking part 30 can be pivoted outwards during the advancing movement of the screwdriver shaft 3.
  • the feed lock is released and the magazine strip 18 can be moved on to a further position, this process being explained in detail later.
  • a spring body arranged in a longitudinal recess 34 on the lever 29 is provided as the locking part 30, this locking part 30 having at its free end an angled, freely projecting arm 35 which provides the feed stop for the magazine strip 18 forms.
  • the locking part 30 bears against one side wall 36 of the longitudinal recess 34, the other side wall 37 of this longitudinal recess 34 forming a movement limitation for the locking part 30 in the lateral pivoting direction.
  • the locking part 30 is thus held in the plane of the lever 29 as well as springs swingable transversely to its level. This is the only way to ensure proper function as a feed lock and to properly trigger the feed lock.
  • the locking part 30 can be fastened in a structurally simple manner to the bolt 32 forming the axis of rotation for the lever 29. It is also possible in this way to form the locking part 30 from a spring steel wire, since this is due to the stops on the side walls the 26 and 37 receives sufficient stability.
  • a leaf spring 30 can be used in a simple manner, which can be fastened to the outer wall of the housing 17 by screws 39.
  • This leaf spring 38 covers with its free end the lever 29 on the outside of the housing 17.
  • the magazine strip 18, which is provided with screws 7, is inserted into the setting tool 1 in the direction of arrow 40, specifically into the feed channel 19.
  • the drive wheel 28 engages in the toothing 28 of the magazine strip 18 and causes the magazine strip 18 to be transported further by the rotary drive of the screwdriver shaft 3 until the first locking cam 31 comes into contact with the arm 35 of the locking part 30.
  • This arm 35 and thus the locking part 30 are pivoted out by the contact pressure of the locking cam 31 of the magazine strip 18 until the free end of the locking part 30, that is to say the arm 35, comes into contact with the side boundary 37 of the longitudinal recess 34.
  • this end part 41 is freely rotatable in the screwdriver shaft 3 and only when pressed in the screwdriver shaft 3 is coupled directly to the setting tool drive, a gentle attachment to the screw head 6 is possible.
  • the screwdriver shaft 3 is depressed further, the screw 7 is pushed through the magazine strip 18, the screwdriver shaft 3 also being guided downward through the magazine strip 18 until the screwing process is complete.
  • the lever 29 see FIG. 6) is pivoted out, so that the locked position of the lever 29 or the locking part 30 is released.
  • the screwdriver shaft 3 holds the magazine strip 18 in place at this time, the feed lock is not required at this time.
  • a spring-loaded ball 53 or a corresponding bolt acts on the adjusting screw 12.
  • the adjusting screw 12 has one or more longitudinal grooves in the area of the thread, so that it can be fixed in different setting positions, since the ball 53 can snap into the corresponding grooves on the adjusting screw 12.
  • a spring body 55 is provided which engages through an opening 63 in the interior of the nut.
  • the housing 17 ends at its free end in two bow-shaped support parts 45, with which the setting tool 1 can be placed on the part to be screwed.
  • a profile piece 46 can be attached to a support part 45, e.g. by a releasable snap connection 56 in order to achieve centering in the case of special screw connections.
  • the profile piece 45 shown is used for screw connections on the crest of a trapezoidal sheet. This ensures a screw connection in the middle of the profile elevation. Depending on the area of application, different profile pieces can be used here.
  • a locking part 70 which is designed in one piece with the lever 29 and is designed as a latching lug, is provided.
  • the lateral displaceability for performing the required movements is taken over by the entire lever 29.
  • the lever 29 can be displaced in the direction of its pivot axis 32 against the frictional force of the pressing leaf spring 38, specifically in the area between the two housing boundaries 71 and 73.
  • Extension 33 is a side boundary 74 of this extension 33 aligned at an acute angle to the pivoting plane of the lever 29.
  • This acute-angled side limitation 74 cooperates with the fixed housing limitation 71, so that when the lever 29 is pivoted out in the direction of arrow 75, the lever 29 is forcibly moved in the direction of arrow 76 (FIG. 11), the frictional force between the pressing leaf spring 38 and the outer surface of the lever 29 must be overcome.
  • the locking part 70 provided here is designed as a latching lug, which has a latching stop 72, which comes into contact with the latching cams 31 of the magazine strip.
  • the locking part 70 On the side opposite the detent stop 72, the locking part 70 has a sloping boundary 77.
  • a screwing operation is also to be explained below for this embodiment according to FIGS. 7 to 11:
  • the magazine strip 18, which is covered with screws 7, is inserted into the setting tool 1 in the direction of arrow 40, specifically into the feed channel 19.
  • the drive wheel 20 engages in the toothing 28 of the magazine strip 18 and causes the magazine strip 18 to be transported further by the rotary drive of the screwdriver shaft 3 until the first locking cam 31 comes into contact with the locking part 70 designed as a snap-in lug.
  • This locking part 70 and thus also the entire lever 29 is displaced against the housing limitation 71 while overcoming the frictional force between the leaf spring 38 and the associated surface of the lever 29.
