Open Fixture System for Aeronautical Complicated Parts and Its Application Method

Abstract

The invention provides an open type clamp system for an aviation complex part. The open type clamp system comprises a foundation plate (1), process bosses and a plurality of compressing blocks, wherein the foundation plate (1) is fixed to a workbench of a machine tool, the process bosses and the compressing blocks are all fixed to the foundation plate (1), and the aviation complex part (7) is positioned and compressed on the foundation plate (1) through the process bosses and the compressing blocks. An application method for the clamp system comprises the steps that in the machining process, the aviation complex part is firstly positioned on a long-strip-shaped boss and a cylindrical boss through fasteners, and then the end parts of the aviation complex part are compressed through the pressing blocks so as to fix the aviation complex part on the foundation plate. According to the open type clamp system and the application method, the time in the tooling and the aligning processes can be shortened, the interference possibility of a tool and a clamp in the machining process can be decreased, meanwhile, the machinable area of the aviation complex part can be increased, and the method is different from a traditional clamp multi-point orientation and multi-point constraint method.

Description

technical field [0001] The invention relates to a fixture, in particular to an open fixture system for aviation complex parts and its application method. Background technique [0002] The open clamping method of parts and the complex structure of aviation parts are mostly processed by four-axis and five-axis linkage CNC machine tools. However, ordinary fixtures cannot expose more processing areas due to the interference of the pressure plate, which affects the processing efficiency, and cannot realize multi-axis processing. [0003] The fast positioning method of the parts, through the cooperation of the pins and the holes, the parts can be quickly and accurately installed on the fixture, and it is no longer necessary to make a watch for alignment during processing. [0004] For special-shaped aviation parts, the irregular shape leads to the interference between the tool and the fixture during processing due to the large number of fixed modules and the large volume of ordin...

Problems solved by technology

[0004] For special-shaped aviation parts, the irregular shape leads to the interference between the tool and the fixture during the processing due to the large number of fixed modules and the large volume of the ordinary fixture during the clamping process.

At the same time, due to the large number of fixed modules, the tooling process is more complicated, and the locking and positioning takes a long time
