Will be adsorbed and fixed to the table 1 via the plywood 15. The machining material 7 is machined or the like while being fixed in this manner.

[Problems to be solved by the device]

As described above, conventionally, since the plywood 15 which is airtight and has no air permeability is used as the material fixing plate, in order to suck and fix the processing material 7 on the upper surface of the plywood 15, the slot 16 is NC.
It was necessary to use a machine or the like to make the width more uniform than the finishing allowance on the outer circumference of the machining. Further, when the processing material 7 and the plywood 15 are leaked during processing, or when the processing material 7 is removed and the chips are cleaned after the processing, the vacuum pump easily enters the hole 17, so that the vacuum pump It is also the cause of the breakdown. In order to solve such a problem, the invention according to claim 1 of the present invention does not require machining or the like, can be manufactured extremely easily, and the chips are sucked by a vacuum pump or the like. It is an object of the present invention to provide a material fixing plate that prevents the above. Another object of the invention according to claim 2 is to provide a material fixing plate having a strong suction force and having the above-mentioned action.

[Means for Solving the Problems]

The present invention has been made in order to solve the above problems, and is a region for forming a material fixing plate of a breathable material that allows circulation of suction air and sucking the material on the surface of the material fixing plate. The problem is solved by using the material fixing plate which is coated so that suction air cannot pass through, in the predetermined regions other than the above.

[Action]

In the invention according to claim 1, since the material is adsorbed and fixed to the breathable material fixing plate as described above, the material fixing plate functions as a filter, and even if leakage occurs during processing, the chips are not generated. It is completely filtered off by the material fixing plate and not sucked by the vacuum pump. Further, since the material can be sucked on the entire surface in contact with the material fixing plate, strong suction can be performed. Further, by coating the material fixing plate made of a breathable material, it can be manufactured extremely easily. In the invention according to claim 2, since the material fixing plate is provided with a hole groove which does not reach the bottom portion on the contact surface with the material,
The suction resistance is reduced and the suction force is further strengthened.

An embodiment of the present invention will be described below with reference to the drawings. First
1 and 2 show one embodiment of claim 1. The same components as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted. In FIGS. 1 and 2, a breathable material fixing plate (hereinafter referred to as a fixing plate) 10 is attached to the table 1 of a processing machine (not shown) or the like.
Then, the working material 7 is positioned and placed on the fixed plate 10 using a positioning device (not shown), and the position is traced on the outer peripheral edge of the working material 7 in contact with the fixed plate 10. After applying a coating for making the open surface of the fixing plate 10 other than the processing material 7 non-breathable to a point slightly inward of the tracing line to form the coating film 11 to be non-venting, the processing material 7 By positioning and activating the vacuum pump (not shown) to remove the air in the fixed plate 10 from the suction hole 5,
The fixing plate 10 is attracted to the table 1 and the processing material 7
The bottom surface 8 of the is adsorbed on the contact surface 12 of the fixed plate 10. Therefore, the processing material 7 is adsorbed and fixed to the table 1 via the fixing plate 10. After fixing the processing material 7 in this way, the positioning device is removed and the processing is performed manually or by operating the NC device or the like. When the breathable fixing plate 10 is used, the processing material 7 can be freely positioned and installed anywhere on the entire surface of the fixing plate 10, and the other open surface can be easily sealed with the coating film 11. You can If there is no pinhole, this coating film 11 does not leak and a thin wall and a perfect seal can be easily obtained. The breathable fixing plate 10 used here is formed by crimping a fibrous material, and is, for example, Starwood (trade name). Further, as the coating material for forming the coating film 11, a material having good releasability with respect to the fixing plate 10 can be used, and the fixing plate 10 can be used many times for processing materials of various sizes. If the materials are of the same size or are not used repeatedly, peeling does not matter and any type of paint may be used. Then, for example, a clear lacquer is used. FIG. 3 shows an embodiment of claim 2 of the present invention. The contact surface 12 on which the processing material 7 is placed is fixed to the fixed plate 10 as described above. A groove hole 14 having a depth not reaching the bottom surface 13 is formed. By providing such a slot 14, the thickness of the suction layer of the fixed plate 10 is substantially reduced, and the suction resistance is reduced and the suction force is increased without lowering the strength of the fixed plate 10. be able to.

[Effect of device]

As described above with respect to claims 1 and 2 of the present invention, since a breathable fixing plate for adhering the processing material to the table is applied, it is possible that scratches that reach the fixing plate with a cutting tool or a drill, etc. during processing. Even if a leakage occurs due to the cutting, or the chips are not sucked by the vacuum pump due to the filter action of the fixing plate 10 even during the cleaning of the chips after removing the processing material, the vacuum pump and the middle of the vacuum pump The pipe is clogged,
This has the effect of preventing damage or damage. In addition, by applying the outer shape that conforms to the shape of the processing material that comes into contact with the material fixing plate, it is possible to completely de-air the predetermined surface of the material fixing plate and to make the entire surface where the processing material contacts the fixing plate. It has the effect that it can be strongly adsorbed and fixed by being sucked in.If a paint with good releasability is used as the paint for coating, part of the coating should be peeled off and repainted. By modifying the painted part, it is possible to form a non-ventilated part that perfectly matches the shape of the processing material very easily, and it is possible to respond very easily to changes in the shape of the processing material. . Further, in the first aspect, it is not necessary to form a hole for suction in the fixing plate as in the conventional case, so that there is an effect that the processing material can be positioned arbitrarily. The provision of the groove hole which does not reach the bottom on the contact surface of the fixed plate to be placed has an effect that the suction resistance is reduced and stronger suction is obtained.
