Abstract

The invention relates to a pneumatic clamp for blade inner cavity water flow, and belongs to the technical field of space flight and aviation. The pneumatic clamp for the water flow of the inner cavity of the blade comprises a bottom plate, a pushing device is fixedly arranged on one side of the bottom plate, the output end of the pushing device is detachably connected with a pressing block used for pushing the blade, and a first positioning block and a second positioning block which are used for positioning the blade are fixedly arranged on the bottom plate at intervals. A fixing seat is fixedly arranged on the other side of the bottom plate, a plurality of water pipes are arranged on the fixing seat at intervals, and the water outlet ends of the water pipes penetrate through the fixing seat and then are connected with water inlets of blades. The beneficial effects are that labor intensity of workers is reduced, clamping is convenient, the design structure is simple, detection efficiency is greatly improved, and batch production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of aerospace and aviation, and in particular relates to a pneumatic clamp for water flow in a blade inner cavity. Background technique [0002] The measurement of water flow in the inner cavity of multi-connected complex hollow turbine blades is an important detection method for measuring the flow characteristics of aeroengine blades at present, and it is a measurement method that can obtain relatively stable flow data through one measurement. The measurement of water flow in the inner cavity of complex hollow turbine blades is widely used because of its good performance in data reproducibility, stability and noise reduction. However, the existing fixtures for measuring water flow in the inner cavity of multi-connected complex hollow turbine blades need to be tightened manually, and the labor intensity of the operators is extremely high, and it is not easy to judge whether the positioning points are in good ...
