Specifically, if the jig is large, it is difficult to dispose of it, or if there is a possibility that the same jig will be used again, the jig must be stored, and it is necessary to secure a storage place. It is troublesome.

Once the jig is discarded, it is troublesome to form a jig having exactly the same dimensions. Therefore, when the same secondary processing is performed again, the accuracy of the secondary processed product varies due to the difference in the jig. May increase.

The present invention solves the above problems,
It is an object of the present invention to provide an extremely innovative product fixing method and a product processing apparatus, which can stably and accurately fix a product with a simple configuration, and can easily handle a jig.

In addition, since the plate 2 is low cost, it can be discarded after use. It becomes a fixing method.

Since the data used for processing the plate material 2 is CAD data used for manufacturing the product 1,
The plate material 2 can be processed into a shape that can securely fix the product 1, so that it can be used as a jig for secondary processing that requires high precision such as laser processing, and is more excellent in practicality. Product fixing method. Further, the shape of the plate material 2 is stored as data, and even if the used plate material 2 is discarded, a plate material 2 of exactly the same shape can be obtained immediately. Becomes

Since the plate 2 is fixed to the fixing portions 4 provided at equal intervals on the plate 3, the fixing position of the plate 2 can be easily changed to a desired position in accordance with the size of the product 1. Thus, the position of the fixing portion 4 can be easily recognized by the groove portion 10, and the product 1 can be easily and reliably fixed, thereby providing a more practical product fixing method.

Further, since the plate 2 is fixed to the plate 3 via the mounting body 7, it is not necessary to provide a complicated structure for mounting the plate 3 on the plate 2, and a commercially available plate 2 made of carbon steel or the like may be used. The plate material 2 can be easily arranged at a desired position on the plate 3 with a small amount of processing such as providing a through hole.
