This type of fixture can only clamp workpieces with regular outer surfaces. If an irregular workpiece is encountered, clamping cannot be achieved, which makes it difficult for the rotating device to drive the workpiece to rotate.

[0004] Therefore, a drilling machining center machining rotation device is proposed. Utility Model Content
