Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is applied to a table in advance when processing a plate made of a wood-based plate, plywood, resin, particle board, starwood, MDF, light metal, etc. Regarding the scrap plate for NC router that is positioned and fixed on top.

[Prior Art] An NC router 1 for processing a plate made of a wood-based plate, plywood, resin, particle board, starwood, MDF, or a flat plate of light metal, as shown in FIG. A table 3 that moves up and down in the drawing is attached, and the head 2 has a first NC router controller 4 and a second NC.
Whether the router control device 5 is mounted and the ruler stoppers 6a, 6b, 6c are fixed to the two side portions of the table 3
Or it is attached to the bed of Table 3.

When the plate to be processed is placed on the table 3 of the NC router 1 configured as described above and processed, the processing tool may penetrate the plate to be processed of wood.
Instead of being placed on the table 3, a wooden plate or the like is coated on the table 3 or a scraping plate (adsorption jig plate) 7 on which the plate to be processed is placed is used. When using the scrap plate 7, the plate to be processed is positioned at a predetermined position of the scrap plate 7.

A plywood such as a veneer plate having a plate thickness of 9 to 15 mm is used as the scrap plate 7, and as shown in FIG. 2, a groove 8 is formed at a positioning position on the surface of the scrap plate 7 for adsorbing the plate to be processed, A suction hole 9 for communicating with the suction of the table 3 is communicated with the groove 8 from the rear surface to the front surface of the waste plate 7.

When placing such a wasteboard 7 on the table 3 of the NC router 1, the wasteboard 7 is pressed against the three ruler stoppers 6a, 6b, 6c fixed to the two sides of the table 3 to remove the wasteboard 7 After contacting any of the three ruler stoppers 6a, 6b, 6c,
The wasteboard 7 is fixed on the table 3 with bolts or the like.

[Problems to be solved by the invention] However, since the groove 8 and the suction hole 9 are located at positions corresponding to the plate to be processed, the scrap plate 7 has different sizes when processing different types of plates. It is necessary to use different scraps 7 and grooves 8 and suction holes 9 having different sizes, positions or numbers. Therefore, each time a different scrap 7 is set, the scrap 7 is placed on the ruler stopper 6a of the table 3,
Positioned by pressing against 6b and 6c.

By the way, the ruler stoppers 6a, 6b, 6c of the table 3 are made of metal fittings. The scrap plate 7 is damaged at the contact portion with the scrap plate 7, and the positioning accuracy of the scrap plate 7 deteriorates. As a result, the positioning accuracy of the work plate also deteriorates, and as a result, the work accuracy of the work plate deteriorates. There is a problem that the life of the wasteboard 7 is short. Further, there is a problem in that the sensors provided on the ruler stoppers 6a, 6b, and 6c are not pressed due to the damage to the scrapboard 7, and a signal is not reliably output during positioning.

The present invention, by attaching a wear-resistant member such as metal or resin around the contact portion with the ruler stopper and around or around the side surface of the ruler stopper, maintains the positioning accuracy when contacted with the ruler stopper and has a long service life. The purpose of the present invention is to provide a wasteboard for an NC router that can be extended.

[Means for Solving the Problems] In order to achieve the above object, the present invention has a suction hole that is positioned by abutting a ruler stopper on a table of an NC router and that mounts and fixes a plate to be processed. In an NC router processing waste plate provided with grooves, at least a side surface with which the ruler stopper abuts and a portion having a wear resistance such as metal or resin is fixedly attached to the side surface and the vicinity or the entire circumference of the side surface.

[Operation] According to the present invention, by fixing a wear-resistant member such as metal or resin at least at a position where the ruler stopper comes into contact with the ruler stopper, it is provided on the table base when positioning the scrapboard. Since the abrasion-resistant member of the scrap plate is brought into contact with the two ruler stoppers and positioned, the scrap plate can be accurately positioned on the table.

[Embodiment] Referring to FIG. 1, in an NC router scrap plate according to a first embodiment of the present invention, 7 is a scrap plate, 8 is a groove, and 9 is a suction hole. Although the description is omitted because it is the same, in the present embodiment, a wear-resistant member 10a such as metal or resin is provided on the side surface of the discarding plate 7 that abuts the three ruler stoppers provided on the table of the NC router and in the vicinity thereof. , 10b,
Stick 10c. Also, these wear resistant members 10a, 10
b and 10c may be fixed to the side surface of the waste plate 7 with screws 11 or may be adhered.

In this embodiment having such a structure, even if the scrap 7 is brought into contact with the ruler stoppers 6a, 6b, 6c of the NC router 1 shown in FIG. 2, the scrap 7 is not dented or damaged, The metal ruler stoppers 6a, 6b, 6c can be accurately brought into contact with each other for positioning. The scrap 7 is made of wear-resistant members 10a, 10b, 10c.
Even if the metal contacts the metal ruler stoppers 6a, 6b, 6c,
There is an advantage that the life of the wasteboard 7 is extended because it is not dented or scratched. In addition, the ruler stopper 6
The sensors 7 provided on the a, 6b, and 6c are disposed on the scrap plate 7 as the wear-resistant member 10a,
Since it is surely pressed by 10b and 10c, there is an advantage that a signal at the time of positioning is surely output.

In the above embodiment, the wear resistant members 10a, 10b, 10c are fixed to the contact positions of the ruler stoppers 6a, 6b, 6c and their vicinity, but in the present embodiment, the side surface of the waste plate 7 is shown. A wear resistant member may be fixed to the whole and its vicinity.

[Advantages of the Invention] Since the present invention is configured as described above, a wear-resistant member such as metal or resin is fixed to the position where the ruler stopper comes into contact, the vicinity thereof, or the entire circumference of the side surface of the waste plate. By doing so, when positioning the scrap plate, even if the scrap plate is strongly contacted with the three ruler stoppers provided on the table base,
The scrap plate is not dented or scratched by the metal ruler stopper, and the scrap plate can be accurately positioned on the table, and the sensors provided on the three ruler stoppers are used for scraping the scrap plate. It can be reliably turned on by the wear resistant member, and the scrap plate is not dented or scratched, so that there is an advantage that the life is extended.
