A rotary table 4 is provided at the front of the device.

The rotary table 4 has a radial mounting groove 5 formed on its upper surface, and using this mounting groove 5, a first jig A, a second jig B, and a third jig C are mounted at three spaced apart locations.

As shown in FIGS. 3 and 4, the first jig A is provided with a receiving plate 6 and a pressing plate 7 facing each other, which are compatible with the curved plywood W curved into an almost chevron shape, and are installed by fitting into the groove 5. The bent part of the receiving plate 6 is fitted via a key to the shaft 9 supported by the supporting pieces 8, 8, and the pressing plate 7 has bearing fittings 10, 10' attached to the center of both ends, respectively, and an adjustment nut is attached to this. Screw rod 1 screwed together with 11
The cylindrical bodies 13 and 13' into which the cylinders 2 and 12' are fitted are pivotally supported from the left and right sides. The screw rods 12, 12' are connected to substantially triangular swing pieces 15, 15' which are pivotally supported on shaft support pieces 14, 14' diagonally provided below both ends of the receiving plate 6, and the pin 1, respectively.
6 and 16', the base end of the cylinder 17 is attached to one swinging piece 15', and the tip of the piston rod 18 of the cylinder 17 is connected to the other swinging piece 15. 15,1
5' is swung to press the pressing plate 7 in the direction of the receiving plate 6, and tighten the plywood W interposed between the receiving plate 6 and the pressing plate 7.

The shaft 9 has a sprocket 9' attached thereto, and is connected by a chain 20 to a sprocket 19' from an actuator 19 attached to one support piece 8, so that it can rotate during machining.

As shown in FIGS. 5 and 6, the second jig B has supporting pieces 21, 21 erected to be attached to the table 4, and supports the shaft 22. The shaft 22 is provided with a receiving plate 23 and a pressing plate 24 having a curved surface that matches the curved surface molded plywood W, the tube at the bent portion of the receiving plate 23 is fitted into the shaft 22 via a key, and the pressing plate 24 is A beam member 25 made of steel is integrally attached to the upper surface. The beam material 25 has a hole 27 for passing the guide rod 26 at one end and a cylinder 28.
is provided, and the guide rod 26 is passed through this hole 27. The guide rod 26 is attached to a collar 29 fitted to the end of the shaft 22 via a key, and the tip of the piston rod 30 of the cylinder 28 is connected to a collar 31 attached to the shaft 22.

The other end of the beam 25 is a support plate 32 fitted to the shaft 22.
The piston rod 34 of the cylinder 33 is pivotally supported on the
A metal fitting 35 provided at the tip of the metal fitting 35 is locked and connected. The metal fitting 35 is formed to have a C-shaped vertical cross section, and is configured to be able to be attached to and detached from the beam material 25 having a cross-sectional shape.

Further, the shaft 22 is provided with a sprocket 22', which is connected to the sprocket 36' of the actuator 36 attached to one of the support pieces 21 via a chain 37, and when the machining of one end edge of the plywood W is completed, the shaft 22 is rotated by 90 degrees. The support pieces 21 and 21 are moved so that they are caught by a stopper 40 passed between them.

The third jig C shown in FIG. 7 has the same structure as the tightening mechanism of the first jig A, except that the
Long holes 39 are arranged in parallel to 8, and when holes are to be drilled at necessary locations on the plywood W, holes are drilled along the long holes 39 using a router.

[Effect]

In the present invention, jigs A, B, and C are appropriately arranged on a table 4 provided on a machine stand 1, and a plywood W is set on each jig, and the router of the NC router processing machine 3 facing the plywood W is set. Under NC control, the router of the head 2 performs processing while rotating under the drive of the actuator 19 to process the side edges of the plywood W, and when this process is completed, the plywood W previously set in the second jig B is processed. When the table 4 is rotated and stopped at the indexed position, the corresponding router of the head 2' of the router processing machine 3 processes one end edge under the control of the NC at this stopped position, and when this process is completed, the actuator 36 in
Rotate it 90 degrees and process the other edge of the plywood W. During this processing, the plywood W set in the third jig C is rotated and stopped at a predetermined position indexed, and a long hole 39 is drilled in the pressing plate 38 by the router of the corresponding head 2''.
This involves drilling holes in the plywood W along the lines.

[Effect of idea]

Originally, it was necessary to tilt the blade to cut the periphery while the workpiece was stopped, but the first jig of the present invention cuts the workpiece while rotating, so the blade must be tilted. You don't have to do it. In addition, the workpiece made of plywood pre-formed into a chevron shape may have irregularities in the product, but the jig of the present invention adapts to the curved shape and tightens and fixes it, so it can deal with irregularities, and the first jig and the second jig
Since the jigs are structured so as not to interfere with the cutting of the peripheral edge, the cutting of the peripheral edge can be smoothly performed using two jigs.
