来るという優れた効果が奏される。<Effects of the invention> As described above, according to this invention, the inner surface of the workpiece of the hollow rough material can basically be used as the reference surface for setting the reference hole for post-processing. The excellent effect of being able to perform processing accurately and efficiently is achieved.

部を有していてもその内側面に正確な基準穴を容
易に設けることが出来るという効果が奏される。 That is, when such a device is inserted inside a hollow material workpiece, the cylinder is operated to lower the shaft, and the corresponding second pawl is slid horizontally through the inclined surface of the shaft, and at the same time the hook is lifted. By releasing the downward displacement restriction of the bush, the bush is displaced downward by the elastic force of the elastic body, and the corresponding first pawl is slid in the horizontal direction via the inclined surface. Since the claws extending in multiple directions can be brought into pressure contact with the inner surface of the hollow material workpiece, it is possible to press the claws that extend in multiple directions into contact with the inner surface of the hollow material workpiece. The effect is that an accurate reference hole can be easily provided on the inner surface of the same.
したがつて、該中空部の複雑な形状やその加工
誤差がある場合でも中空部内面の誤差をある幅を
もつて補うことが出来、許容範囲の正確さで位置
決めが出来る優れた効果が奏される。 Therefore, even if the hollow part has a complicated shape or there is a processing error, the error in the inner surface of the hollow part can be compensated for within a certain range, and an excellent effect can be achieved in which positioning can be performed with tolerance accuracy. Ru.
又、基準穴設定基準面を中空粗材のワークの内

れる。 In addition, since the reference hole setting reference plane can be provided on the inner surface of the hollow material workpiece, the machining allowance can be made almost uniform when machining the inner surface of the hollow material material workpiece, thereby improving the machining accuracy. Excellent effects such as increased accuracy and improved processing efficiency are achieved.
更に又、可動体に連結された爪がスプリング等

という優れた効果も奏される。 Furthermore, by making the claws connected to the movable body protrude using the elastic force of an elastic member such as a spring, the manufacturing error of each hollow material workpiece is compensated for by its elasticity, and all the claws are always It also has the excellent effect of being able to reliably bring the material into contact with the inner surface of the hollow material workpiece.
