Abstract

The invention provides a universal clamp device for vane overall length machining. The problem that a production cycle is long, and production efficiency is low caused by a square box locating mode in vane overall length machining is solved. The universal clamp device comprises a base and is characterized in that two vane tip branch plates and two vane root branch plates are arranged at the horizontal two ends of the base respectively, vane tip pressing plates and vane root pressing plates are arranged on the longitudinal outer side ends of the two vane tip branch plates and the two vane root branch plates on the base respectively, vane root clamping bases are arranged on the longitudinal outer side ends of the two vane root branch plates on the base respectively, reverse-L-shaped grooves are formed in the top faces of the vane root clamping bases, line alignment blocks for vane forge piece longitudinal locating are placed in the reverse-L-shaped grooves of the two vane root clamping bases and tightly abut against the inner groove walls of the reverse-L-shaped grooves, longitudinal thread through holes are formed in the two vane root clamping bases, and locking screws are arranged in the thread through holes.

Description

technical field [0001] The invention relates to the field of blade processing tooling, in particular to the field of tooling for machining the overall length of guide aluminum alloy blades of civil aeroengines, in particular to a general fixture device for machining the overall length of blades. Background technique [0002] After forging, there will be a draft slope on the top and bottom of the blade forging. In order to meet the design requirements, it is necessary to mill the two ends of the blade forging after forging to make the total length of the blade reach the design value. In the past, the total length of the processing blade was positioned by the square box: firstly, the blade forging was positioned in the square box with a pre-positioning fixture, and then the tin-bismuth alloy was poured into the box, and the tin-bismuth alloy was cooled until it was fully solidified with the blade forging, and then the pre-set was removed. Fixtures are used to mill and process ...
