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.

Description

technical field [0001] The invention relates to the field of tooling for rotary milling of CNC machine tool blades, in particular to a double-top rotary milling fixture. Background technique [0002] During the surface processing of steam turbine blades, most of the blades will use double tip holes as the process benchmark. The medium and small static blades use the double-top holes as the process reference to directly complete the rough and fine milling of the profile; the large static blades and moving blades use the double-point holes as the reference for the rough milling profile and the milling process reference, and then use the process reference as the positioning Fine milling surface, so the double-top rotary milling fixture is very important for blade surface processing. However, due to the difficulty in controlling the depth of the tip holes of the blades, the depths of the tip holes of different blades of the same batch of blades are often inconsistent, and even ...
