Universal clamp

Abstract

The invention belongs to the airplane equipment technology, and relates to an improvement on a universal clamp for airplane assembly tools. The universal clamp comprises at least one connection plate [2], at least two support arms [1] and at least two clamping ends. Oppositely-penetrating connection hole arrays are formed in the four side faces of each connection plate and the four side faces of each support arm. The supporting arms and the connection plates are connected through penetrating and butt joint connection holes. The clamping ends are fixedly connected with the support arms through connection holes. The universal clamp is high in universality, simple in structure and easy to operate; the manufacturing cost of universal tools and assembly tools for airplane manufacturing is reduced, the universal clamp can be assembled into clamps in different sizes according to requirements, and the application range of the universal clamp is widened.

Description

technical field [0001] The invention belongs to the aircraft equipment technology and relates to the improvement of the universal clamp of the aircraft assembly tool. Background technique [0002] In the assembly and manufacturing process of aircraft parts, tools such as universal clamps are often used to clamp the composite material parts on the cutting die with the clamps, cut the periphery of the composite material parts, and use the clamps to position the parts For aircraft assembly, the proportion of this situation is increasing day by day. Since the shapes and sizes of aircraft parts are different, the required clamps have different dimensions. The original clamps can no longer meet the requirements of use, especially for aircraft assembly. When the size is large and the part at the center of the component needs to be positioned and pressed, the positioning clamp and the positioning and clamping parts are generally used for positioning and installation. This will incre...

[0002] In the assembly and manufacturing process of aircraft parts, tools such as universal clamps are often used to clamp the composite material parts on the cutting die with the clamps, cut the periphery of the composite material parts, and use the clamps to position the parts For aircraft assembly, the proportion of this situation is increasing day by day. Since the shapes and sizes of aircraft parts are different, the required clamps have different dimensions. The original clamps can no longer meet the requirements of use, especially for aircraft assembly. When the size is large and the part at the center of the component needs to be positioned and pressed, the positioning clamp and the positioning and clamping parts are generally used for positioning and installation. This will increase the complexity of the assembly fixture structure, so how to reduce the manufacturing of aircraft assembly tooling? cost, with great economic value
