Abstract

The invention discloses a flexible fixture used for processing blade steam passages, relates to the technical field of mechanical processing, and includes clamping mechanisms at both ends and an intermediate auxiliary support mechanism; the intermediate auxiliary support mechanism includes a bottom plate, and two dovetail guide rails are arranged in parallel on the bottom plate , a sliding seat is provided on the guide rail; the annular bracket is arranged on the sliding seat and can slide with the guide rail; a deep groove ball bearing is arranged in the annular support; the bearing and the bushing are interference fit, and there are multiple The bolt is supported, and a contact unit with feedback performance is arranged on the top of the bolt. The contact unit adopts a vibration sensor and a magneto-rheological damper with good high-frequency response performance to enhance the rigidity of the processing process. The invention can adapt to blades of different sizes, has good flexibility, provides auxiliary support when milling a long steam channel, reduces vibration and bending deformation during processing, can effectively reduce deformation of the steam channel, and improves machining accuracy.

Description

technical field [0001] The invention belongs to the technical field of mechanically processing complex thin-walled parts, and in particular relates to a special flexible fixture used for processing steam passages of steam turbine blades. Background technique [0002] Steam turbines are widely used in thermal power generation, nuclear power, aviation, ships and other fields. The steam turbine has high efficiency and long service life, and is still the most important prime mover for thermal power generation enterprises. As the key component with the largest number in steam turbine equipment, the blade needs to work in extremely harsh environments such as high temperature, high pressure, and high speed. In order to meet its performance and high reliability requirements, the processing quality of steam turbine blades is very important. However, steam turbine blades are thin-walled parts with complex structures and poor rigidity. For blades with long steam passages, problems suc...
