Adjustable clamp based on aviation part machining

Abstract

The invention discloses an adjustable clamp based on aeronautical part machining, and relates to the field of aeronautical part machining, the adjustable clamp comprises two sets of symmetrically arranged clamping mechanisms, and the two sets of clamping mechanisms can move relatively to form a clamping space; the clamping mechanism comprises a base and a first clamping block, the first clamping block is arranged on the base in a sliding mode, a plurality of second clamping blocks are arranged on the first clamping block in the radial direction of the first clamping block in a sliding mode, and the sliding paths of the first clamping block and the second clamping blocks are both in an arc shape. The two sets of clamping mechanisms are used for clamping parts in different shapes through arc-shaped deflection of the first clamping blocks and the second clamping blocks. A clamping space is formed between the two sets of clamping mechanisms, and the shape of the clamping space can be adaptively adjusted according to the shape of a part, so that the clamping area is increased, the clamping strength is improved, the part is clamped more stably, and high-strength machining of the part is facilitated.

Description

technical field [0001] The invention relates to the field of aviation parts processing, in particular to an adjustable fixture based on the processing of aviation parts. Background technique [0002] With the development of society, the aviation industry is also progressing by leaps and bounds. The development of aviation has greatly changed the structure of transportation. Airplanes provide people with a fast, convenient, economical, safe and comfortable means of transportation, and become the means of intercontinental travel for people. The main tool has closely connected the exchanges of countries all over the world; in the aviation parts, most of the plate parts are processed, such as the shell plate, the wing plate, etc., because the flight design requires that the shape of the aviation shell is basically streamlined, That is, the casing plate is composed of a number of special-shaped plates with curved surfaces. Due to the special type of aviation plate, the fixture ne...

[0002] With the development of society, the aviation industry is also progressing by leaps and bounds. The development of aviation has greatly changed the structure of transportation. Airplanes provide people with a fast, convenient, economical, safe and comfortable means of transportation, and become the means of intercontinental travel for people. The main tool has closely connected the exchanges of countries all over the world; in the aviation parts, most of the plate parts are processed, such as the shell plate, the wing plate, etc., because the flight design requires that the shape of the aviation shell is basically streamlined, That is, the casing plate is composed of a number of special-shaped plates with curved surfaces. Due to the special type of aviation plate, the fixture needs to have strong adaptability and adjustment ability, and can adjust the clamping form to adapt to the shape of the plate. Now Some fixtures cannot be adaptively adjusted according to the shape of the board, resulting in poor clamping effect and unstable clamping of aviation special-shaped boards, and it is easy to cause the board to shift or fall off during processing, especially when cutting , grinding and other processing procedures that will generate large vibrations, thereby reducing the processing accuracy of aviation panels
