Abstract
The invention provides a double tip rotary mill clamp which solves the problem that the blade is clamped unstably due to the fact that the extending length of a single tip for the current clamp cannot be adjusted, so as to ensure the profile machining quality of the blade and improve the machining speed as well as solve the problem of poor universality and high tool cost. The double tip rotary mill clamp comprises a tip base and two positioning tips. The two positioning tips are installed on the tip base in parallel. The tip base is installed on a numerically-controlled machine tool. The double tip rotary mill clamp is characterized in that the tip base is integral, and the two positioning tips are installed on the integral tip base through a tip support plate. The integral tip base is internally provided with an adjusting mechanism which adjusts the extending lengths of the two positioning tips simultaneously, wherein the two positioning tips are connected with the adjusting mechanism.
