DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a positioning ruler for an NC router in which two or more processing plates are positioned and processed on a suction table by a ruler provided on two sides of a suction table. Things.

[0002]

2. Description of the Related Art In a conventional NC router, as shown in FIG. 6, a ruler B is attached to a table A, a discarded plate C is positioned in accordance with the ruler B, and then mounted on the discarded plate C. The wood processing board E is positioned by the ruler D.

[0003] In the conventional NC router table A constructed as described above, the ruler D attached to the discarded plate C interferes with the blade F when processing the outer periphery of the wood processing plate E. It is configured so as to be able to be manually removed every time the wood processing board E is set.

[0004]

Further, since the rulers B and D protrude from the table A and the discarding plate C, dust cannot be collected on the discarding plate C and the wood processing plate E, and furthermore, complicated cutting is performed. In this case, the ruler D of the disc C becomes a hindrance, and the blade (spindle spindle) may hit the rulers B and D due to malfunction or programming error, etc. to break the machine, or the blade F may be chipped and fly. Was dangerous.

Further, since chips are attached to the corners between the rulers B and D and the table A or the discarded plate C, the end face of the discarded plate C or the processed wood plate E may not hit the rulers B and D, and the accuracy is maintained. There was a problem that was impossible.

[0006]

According to the present invention, there is provided one or more spindle motors having a rotary shaft on which a tool such as a drill or a cutter is mounted on a head structure which is moved along a rail provided on a support table. In the NC router, the head is mounted, and the suction table is moved to process a wood processing board positioned on the suction table or the discard plate. A fixed support member is provided with a ruler stopper that moves back and forth by two or more cylinders for positioning one side of the processing plate, and a drive shaft that positions the long side of the processing plate on the support member outside the long side of the suction table. Is provided with a ruler stopper which moves back and forth by a plurality of cylinders having different strokes.

[0007]

According to the present invention, a ruler stopper is provided on the short side of the suction table to divide the suction table into at least two parts from the center and to position each of the work plates.

A cylinder for moving a ruler stopper for a work plate positioned on the near side from the center of at least two suction tables on the long side of the table, and a work plate farther from the center of the suction table. By providing a ruler stopper for positioning a ruler stopper and a cylinder that moves back and forth, at least two processing plates can be processed.

FIG. 1 is a plan view of an NC router according to an embodiment of the present invention, FIG. 2 is a plan view of a ruler provided on a suction table of the NC router of FIG. 1, and FIG. FIG. 2
FIG. 4 is a side view of the ruler device of FIG. 2 as viewed from the short side of the table. A rail 2 is mounted on a support table 1 and a head structure 3 of FIG. It is supported to move left and right.

A head 4 is mounted on the head structure 3, a spindle motor is mounted on the head 4, and a tool such as a drill or a cutter is mounted on a rotating shaft of the spindle motor. I have.

A tool changer 5 and a tool magazine 6 are mounted on the side of the head 4, and a large number of tools 7 are mounted on the tool magazine 6. Depending on the configuration of a part to be machined, the head 4 has the necessary tools 7. It is configured to be exchangeable.

Further, a rail 8 is mounted on the support table 1 below the head 4, and a suction table 9 is mounted on the rail 8 so as to move forward and backward of the head 4, and safety fences 10 are mounted on both sides of the head 4. Have been.

At one corner of the suction table 9, on the long side of the suction table 9, a ruler device 12 is attached to a support member 11 fixed to the support base 1 at a desired distance from the suction table 9.
A cylinder 14 for moving a ruler stopper 13 for positioning a work plate placed on the near side by dividing the suction table 9 into two parts from the center of the ruler device 12 and a tip for dividing the suction table 9 into two parts. Is provided with a cylinder 16 having a long stroke of a drive shaft for moving a ruler stopper 15 for positioning a work plate.
Limit switch 1 for checking the contact of the processed plate
7, 18 are provided.

On a short side of the table 9, a ruler device 20 is mounted on a support member 19 fixed to the support table 1 at a desired distance from the suction table 9. The ruler device 20 includes Cylinder 22 for driving a ruler stopper 21 for positioning the work plate on the near side obtained by dividing 9 into two
A cylinder 24 for driving a ruler stopper 23 for positioning the work plate is mounted on the side where the suction table 9 is divided into two parts, and limit switches 25 for checking the contact of the work plate with the ruler stoppers 21 and 23 respectively. , 26 are provided.

In the positioning ruler according to the present embodiment having the above-described structure, first, when the work plate is placed on the two divided sides of the suction table 9, the stroke of the drive shaft of the ruler 12 becomes longer. By driving the cylinder 16 and the cylinder 23 of the ruler device 19, the ruler stopper 15 and the ruler stopper 22 are driven.
Is applied to the work plate, and the positioning of the work plate is checked by the limit switches 18 and 24 for confirmation.

Next, when the work plate is placed on the near side of the suction table 9 divided into two, the cylinder 14 having a short stroke of the drive shaft of the ruler device 12 and the cylinder 2 of the ruler device 19
1 is driven to bring the ruler stopper 13 and the ruler stopper 20 into contact with the work plate, and the position of the work plate is confirmed by the limit switches 17 and 23 for confirmation.

With this configuration, two processing plates can be positioned at the same interval on the suction table 9 at a time. By moving the head 4 by a predetermined distance, the processing can be performed. The same working step can be applied to two working plates.

When two or more processing plates are processed using two or more heads, the same processing can be performed simultaneously.

In the above embodiment, the contact of the work plate is confirmed by the limit switches 17, 18, 25, and 26. However, without providing the limit switches, the cylinders 14, 16 and 22, 24 may be moved to hit the work plate.

When the discarding plate is positioned in front of the suction table 9 before machining, the discarding cylinder 27 between the cylinder 14 having a short stroke of the drive shaft of the ruler device 12 and the cylinder 16 having a long stroke. By driving the cylinder 21 of the ruler device 19, the ruler stopper 13 and the ruler stopper 2
0 may be applied to the discard plate for positioning. However, when the discarded plate and the processed plate are positioned on the tip side of the suction table 9, as shown in FIG. A jig 30 having a work contact surface 30a and a work plate contact surface 30b for positioning the work plate 29 may be provided on the drive shaft 16a of the cylinder 16 having a long stroke.

Further, in the above embodiment, two work plates are positioned on the suction table 9, but by mounting a large number of cylinders having different drive shaft strokes to the ruler device 12, A large number of processing plates can be positioned and processed on the suction table 9.

[0022]

As described above, the positioning ruler for an NC router according to the present invention can position a plurality of processing plates at predetermined intervals on a suction table, so that the same processing step can be performed by a head. The same processing can be performed simply by moving the head by a predetermined distance.If a large number of heads are used, the same processing can be performed simultaneously by processing the heads at a predetermined interval. There is an advantage that you can.
