A kind of flexible tooling and using method thereof

Abstract

The invention relates to novel flexible tooling and a using method thereof. The novel flexible tooling is used for clamping a part casing. The tooling comprises a circular bottom plate. A circular convex platform is arranged on the circular bottom plate. A plurality of sets of clamping mechanisms are arranged on the circular bottom plate in the circumferential direction. A clamping structure clamps and positions a supporting plate of the part casing. A plurality of positioning pins are further arranged on the circular bottom plate in the circumferential direction. The positioning pins are horizontally placed. The end parts of the positioning pins are aligned with the supporting plate. According to the novel flexible tooling, the monomer positioning function during assembly welding and themonomer position measuring function after part welding are realized, the measuring cost and the part turnover cost after part welding are almost reduced to zero, the correction and measurement of theparts can be completed at a time on the tooling, the deviation of the parts is very intuitive, the correction efficiency is greatly improved, and the machining quality is improved; and through matching of the positioning pins and conical blind holes, positioning and measuring of the parts are completed, the positioning precision is high by using the tooling for positioning, positioning and measuring functions are flexibly switched, and the integrated functions of flexible welding-measuring are achieved.

Description

Technical field: [0001] The invention relates to the technical field of aero-engine welding, in particular to a flexible tooling and a using method thereof. Background technique: [0002] Fusion welding processing is an important processing method second only to mechanical processing in the manufacturing industry, and the processing method of "large-scale welding assembly welding processing" is a typical processing structure in fusion welding. Therefore, improving the processing quality of "large-scale welding assembly welding processing" is of great significance to improving the processing level of the welding industry and even the manufacturing industry. [0003] The biggest technical difficulty faced by "large-scale welded assembly welding processing" is the guarantee of the positioning accuracy of the individual components before the assembly is welded, and the continuous processing process of the high-precision and efficient measurement of the parts after the welding is...

AI Technical Summary

Problems solved by technology

[0004] The existing processing method is to use special welding positioning welding clips to measure the parts. Since the benchmark needs to be transformed during the measurement, the accuracy of the measurement results is greatly reduced. At the same time, the calibration and measurement of large-scale welding components are carried out independently. To real-time correspondence, this makes the accuracy of part calibration very low, and the measurement and calibration need to be repeated many times, which further greatly increases the cost of calibration and measurement of parts, and greatly prolongs the processing cycle
