Problems solved by technology

[0002] At present, in the machining of small-volume special-shaped parts of aircraft, special-shaped special-shaped parts that are difficult to clamp are generally processed by custom-made special tooling, multiple clamping through three-axis CNC equipment, or high-end CNC machine tools such as five-axis. For parts with special shapes that are difficult to clamp, different sizes, and thin wall thickness, the difficulty of clamping and processing is often greater, the processing cycle is long, and the technical requirements are high. A little carelessness will affect the processing accuracy or even be scrapped. parts, resulting in increased costs and inefficient processing

Abstract

The invention discloses an auxiliary device for clamping special-shaped parts of an aircraft and a clamping method thereof, which comprises a cylindrical rotating body, two ends of the rotating body are respectively provided with cylindrical clamping ends and fixed ends; The surface on one side of the end is provided with two planes. The two planes are symmetrical with the axis of the revolving body. The clamping surface is provided with several screw holes, and both ends of the clamping surface are provided with fixed bosses. Two bolt holes are provided on the fixed boss, and pin holes are set between the two bolt holes. The clamping method includes steps S1-S14. By designing different stations on the same rotary body, the invention can assist CNC machine tools to process aircraft special-shaped and difficult-to-machine parts, avoid multiple clamping and the use of special tooling in the processing process, improve processing efficiency, and ensure the size of the parts. Accuracy and Geometric Accuracy.

Description

technical field [0001] The invention relates to the technical field of aircraft special-shaped parts processing, in particular to an aircraft special-shaped part clamping auxiliary device and a clamping method thereof. Background technique [0002] At present, in the machining of small-volume special-shaped parts of aircraft, customized special tooling is generally used for special-shaped parts that are difficult to clamp, and three-axis CNC equipment is used for multiple clamping, or high-end CNC machine tools such as five-axis are used for processing: and For special-shaped parts that are difficult to clamp, different in size, and thin in wall thickness, the clamping difficulty and processing difficulty are often greater, the processing cycle is long, and the technical requirements are high. A little carelessness will affect the processing accuracy or even scrap it parts, resulting in rising costs and inefficiencies in processing. SUMMARY OF THE INVENTION [0003] In vi...
