孔にドリル等の工具を合わせ孔明加工を行なっていた。[Technical Background of the Invention and Problems Therein] Conventionally, a hole drilling process ρ4 of a turbine rotor wheel pin is performed. As shown in FIGS. After hooking, the hole making jig 3 is fixed at the π position of the turbine wheel 1 by tightening the tightening screw 4a, and a tool such as a drill is aligned with the hole of the hole making jig 3 on the ridge to perform the hole drilling process.

つきが生じやすい等の欠点があった。According to such a drilling method, the holes of the drilling jig 3 need to be in group phase in order to perform drilling with high precision and efficiency. Therefore, the size of the jig body increases, the number of prisoners M increases, and it is difficult to install and remove the jig at the drilling position, so it is necessary to erect a scaffold on top of the wheel to install and remove it, resulting in poor tillage efficiency. In addition, since it is necessary to drill many holes with the same mounting jig, it is necessary to provide a large number of holes in the jig body.
The manufacturing cost of the jig was high because a large number of precision holes had to be made in the jig. Furthermore, during drilling, since a drilling tool such as a drill is aligned with each hole position of the jig, there are drawbacks such as the accuracy of the processed hole position (2L1 fluctuation is likely to occur).

が得られる。In Komei's method, the rotor wheel l is rotated and indexed and fixed in a fixed position using a device such as an indexing gear attached to the rotor wheel. Next, the jig main body 5 is pressed against the rotor wheel l by the hydraulic cylinder 6. By indexing the rotor wheel 1 with high precision and setting the jig main body 5 in a fixed position, the drilling machine can perform the drilling process 7 in a constant cycle, so that pin drilling can be achieved with high precision and high efficiency.

比べ高精度の孔明加工が出来る。According to the invention described above, only the turbine rotor wheel is rotated fully for indexing, so the drilling jig can be made compact, and the jig can be installed and removed using a hydraulic cylinder, etc. Workability is improved and processing time can be shortened. In addition, the indexing device and drilling jig are
Since positioning can be performed with high precision, it is possible to perform drilling with higher precision than with conventional drilling methods.
