Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic tacker applied to, for example, airframe assembly of an aircraft.

[0002]

[Prior Art]

 FIG. 4 is a structural explanatory view of a conventional nut plate automatic tacker used for assembling an airframe of an aircraft. In the figure, the conventional nut plate automatic tacker pushes the rivet 01 made of aluminum into the upper anvil 02 by the rivet supply anvil 03 and pushes the rivet 01 by the rivet hitting anvil 04 into the hole of the work 05. insert. Then, although not shown, a lower cylinder provided below the work 05 is raised to caulk the rivet 01, and the conventional upper anvil 02 supplies the rivet 01 by the hanging and pushing method, It requires two anvils, a bet supply anvil 03 and a rivet hit anvil 04.

[0003]

[Problems to be solved by the device]

 In the conventional nut plate automatic tacker as described above, the rivet 01 used for mounting the nut plate is extremely small as shown in the figure. The stable supply of rivet 01 cannot be achieved because 01 drops out. Further, the apparatus becomes large in scale because two anvils for supplying the rivet 01 and for hitting the rivet 01 are required.

[0004]

[Means for Solving the Problems]

 The automatic tacker according to the present invention is intended to solve the above-mentioned problems, and a rivet is supplied from an anvil facing one surface of a work to a hole drilled in the work and the board is driven. In addition, in the automatic tacker that crimps the rivet from the other side of the work, the end surface of the anvil is rotatably provided parallel to one surface of the work, and the rivet is attached to the end surface of the anvil. The present invention is characterized in that a supply hole for supplying to the hole and a plate part for pressing the rivet are provided.

[0005]

[Action]

 That is, in the automatic tacker according to the present invention, the rivet is supplied from the anvil provided facing one surface of the work to the hole drilled in the work to hit the board and the other side of the work. The end face of the anvil in the automatic tacker that crimps the rivet is rotatably provided parallel to one surface of the work, and the end face of the anvil is provided with a supply hole for supplying the rivet to the work hole and a rivet. A board part is provided, and the rivet is directly supplied from the supply hole provided on the end surface of the work, so that the rivet is supplied to the work hole without dropping off. Further, by providing the rivet supply hole and the platen on the end face of the rotatable annbin, the two anvils for supplying the rivet and the plate for the rivet are integrated.

【Example】

 FIG. 1 and FIG. 2 are structural explanatory views of a nut plate automatic tacker according to an embodiment of the present invention, and FIG. 3 is an operation explanatory view. In the drawings, the nut plate automatic tacker according to the present embodiment is used for assembling an airframe of an aircraft. As shown in FIGS. 1 and 2, the work position between the upper anvil 4 and the lower cylinder 11 is shown. The lower cylinder is inserted into the hole, the rivet is supplied from the upper upper anvil 4 to the hole drilled by the drill unit 7, and the lower cylinder is used to caulk the hole while hitting the hole. That is, the drill unit 7 and the upper anvil 4 are advanced downward by the cylinder 10 of the upper device, and the upper anvil cylinder 1 is extended to further descend along the slide bush 2 via the link mechanism 5. ing. The rivet is cut out from the rivet feeder 9 and pressure-fed in the rivet supply tube 3 by air, and is supplied from the rivet supply hole 14 to the hole formed in the work. The upper anvil 4 is rotated by a motor 8 for rotating the upper anvil 4. 6 is a pin for attaching / detaching the anvil attachment. By removing the pin 6, the anvil attachment can be attached / detached with one touch.

When the nut plate 13 is caulked on the work 12 by using a rivet using the present fastener driving tool, first, as shown in FIG. 3, a biaxial hole is formed in the work 12 by the drill unit 7. Then, the drill unit 7 and the upper anvil 4 are lowered by the cylinder 10 of the upper device. Then, when the upper anvil cylinder 1 is extended, the upper anvil 4 descends along the slide bush 2 3 mm before the work 12 via the link mechanism 5. Then, the rivet is cut out from the rivet feeder 9 at the same time on two axes, air is pressure-fed through the rivet supply tube 3 by air, and the rivet is supplied from the rivet supply hole 14 to be inserted into the hole. Then, the upper anvil 4 is rotated by the motor 8 for rotating the upper anvil 4 until the rivet hitting plate portion 15 faces the rivet. Next, the upper anvil cylinder 1 is further extended and the lower cylinder 11 is raised while hitting against the head of the rivet to crimp the rivet and the nut plate 13 is automatically struck by the work. When the fastener driving tool is applied to the nut plates 13 having different hole pitches, the anvil attachment can be attached / detached with one touch by removing the pin 6.

As described above, the two anvils for supplying the rivet and the plate for the rivet are integrated into one anvil so that the apparatus can be downsized. Also, by eliminating the method of pushing out the rivet by hanging, the rivet is fed by air and directly supplied to the hole of the work 12 from the rivet supply hole 14, so that the rivet is reliably supplied without dropping off. It In addition, the range of applicable workpieces 12 is expanded by attaching and detaching the anvil attachment with one touch.

[0009]

[Effect of the device]

 The automatic tacker according to the present invention is configured as described above, and the rivet is supplied to the hole of the work without dropping, so that the supply of the rivet is stabilized. Also, since the two anvils that supply rivets and hit the rivets are integrated, the equipment becomes smaller.
