When milling the side holes of the drill tail, a fixture is required to clamp and fix multiple drill rods to the machining center. The Chinese utility model patent with the prior art publication number CN217667942U proposes a fixture for milling the side holes of the drill tail in a machining center. The fixture has multiple positioning grooves on the limit plate to assist in limiting the horizontal position of the drill tail. Multiple positioning plates are set on the limit plate and the support plate to limit the vertical direction of the limit, so that multiple drill tails can be stably clamped and fixed at the same time, and multiple drill tails can be processed at the same time, thereby improving processing efficiency.
