Flexible fixture device and operation method thereof

Abstract

The invention provides a flexible fixture device and an operation method thereof. The device comprises a root pre-tightening block, an adjustable fixture block, an adjustable fixture support, a clamping block, a base and a clamping fixed piece, wherein the root pre-tightening block and the adjustable fixture support are fixed on two sides of the base respectively through a position regulating mechanism thereon; the clamping block is fixed on the adjustable fixture support through a position regulating mechanism thereon; the adjustable fixture block is hinged on the adjustable fixture support; the root pre-tightening block and / or the adjustable fixture block are / is provided with through holes back and forth respectively; and the through holes are inserted into the clamping fixed piece which performs flexible clamping on the surfaces of processed parts, ensures that the processed parts can obtain effective and even clamping force, and prevents the loosening and shifting during processing. Because the adjustable clamping block and clamping screws are adopted to clamp and position the roots and planes of vanes respectively, the reliable positioning of the vanes is ensured during processing, and shifting is avoided. The whole fixture device has simple structure, reliability, durability and simple operation, and provides good basis for processing and repairing vane parts in high quality.

Description

technical field [0001] The invention relates to a flexible fixture device and its operation method which are applicable to the clamping and positioning of parts in the process of processing and repairing complex curved surface parts in manufacturing and remanufacturing, and belongs to the transformation technology of the flexible fixture device and its operation method. Background technique [0002] In the modern manufacturing industry, mechanical parts are developing towards the trend of small batch, multi-variety, and complexity, and have higher requirements for the geometry, processing technology and flexibility of the parts. The design of the tightening device, that is, the flexible fixture, is very important, and it directly affects the processing quality, efficiency and cost of the parts. [0003] With the increasing shortage of global manufacturing resources, the sustainable manufacturing model has been valued by countries all over the world, and remanufacturing engin...

AI Technical Summary

Problems solved by technology

Different from the manufacturing process of new parts, during the remanufacturing process, most of the repaired parts are worn and deformed, resulting in different geometric shapes, and the difficulty of precise clamping and positioning

For example, in the repair process of compressor and turbine blade parts of aircraft engines, since the deformation of each blade is different, the fixed fixture cannot realize the precise clamping of repaired blades in batches, which affects the repairability and repair efficiency of the blades. Only by designing an adjustable flexible fixture that can adapt to the geometric shape of each part, can repair and mass production of blade parts be possible
