The angle reference processing jig of the invention according to claim 1 is placed on a table 2 such as a machine tool. The jig body block 3 is fixed to a required position. The jig body block 3 has a V-groove portion 4 for attaching a workpiece on one side surface, and the side surface opposite to the V-groove portion 4 A first reference surface 5 that abuts the upper surface of the table 2 is formed, and both side surfaces that extend in the longitudinal direction of the V groove portion 4 adjacent to the first reference surface 5 and the side surface on the V groove portion 4 side are the first reference surface 5. The second reference surface 6 and the third reference surface 7 intersecting each other at a right angle of 90 degrees are formed, and the first inclined surface 4a of the first and second inclined surfaces 4a and 4b forming the V-groove portion 4 is the first inclined surface 4a. The second inclined surface 4b is formed between the second reference surface 6 and the third reference surface 7. Are formed so as to form a required inclination angle β, and the workpiece W is attached to the first inclined surface 4a and the second inclined surface 4b or both the first and second inclined surfaces by the bolt 10 on the inclined surface. The screw holes 8 for fixing in the above are provided at every required interval in the longitudinal direction of the V groove.

  The effect of the invention by the above-described solution means will be described with reference numerals in the embodiments described later. An angle reference machining jig 1 according to the invention according to claim 1 includes a jig body block 3 and a workpiece. Since it is comprised from the bolt 10 which fixes W, and a structure is very simple, handling and operation are easy and easy, and work efficiency improves.

  In addition, according to the angle reference processing jig 1, the workpiece W is, for example, as shown in FIG. 2, the angle formed by the inlet side edge portion A and the outlet side edge portion B is 90 °, and the inlet side edge portion. Grinding is performed on, for example, the outlet side edge portion B of the lip W for the die head in which the angle formed between the extension surface of B and the side surface C is 45 ° and the angle between the outlet side edge portion B and the side surface C is 45 °. In this case, the jig 1 in which the angle α formed by the first inclined surface 4a of the V groove portion 4 and the second reference surface 6 is 45 ° may be used, and the first reference surface 5 is placed and fixed on the table 2. When the side face C of the die head lip W is brought into contact with and fixed to the first inclined surface 4a of the V groove portion 4 of the jig body block 3, the die edge lip W of the die head lip W becomes the jig body. Since grinding is performed using the first reference surface 5 of the block 3 as a reference, the processing accuracy is high. A high and uniform product can be obtained.

That is, after a workpiece is attached to the jig 1, the workpiece is cut (primary machining) by a required machine tool, and, for example, plated to form a plating layer m having a predetermined thickness. Then, for example, grinding (secondary processing) of the plating layer m is performed using the jig 1. In this way, if the same angle reference processing jig 1 is used for primary processing and secondary processing, primary processing and secondary processing can be performed on the same standard, so processing accuracy (parallelism, squareness, flatness, straightness) The film thickness of the surface treatment such as plating performed after the primary processing becomes stable and uniform, and the quality of the product is improved.

  Furthermore, according to the angle reference processing jig 1 of the present invention, when the workpiece W is a non-magnetic material such as a non-ferrous metal or a synthetic resin, it is particularly effective. That is, even when the workpiece W is a non-magnetic material that cannot be attracted to the table 2 by a magnet, the workpiece W can be fixed to the table 2 via the jig body block 3 and processed.
