Abstract

The invention relates to a combined skin face measuring flexible multi-point support device, adopting a modularization design idea. The whole device is composed of a plurality of positioning plates and shape-regulating components. The positioning plate appears as a flat T-shape, and screw holes and matching faces are arranged on the plate. The shape-regulating component consists of a basic pillow and a nail-height regulating unit. The shape-regulating component is horizontally arranged along X direction, and the central distances are all fixed. The positioning plates are divided into two symmetrical lines along Y direction, and each positioning plate is connected with the same end of two neighboring shape-regulating components. The shape-regulating components and positioning plates of different quantities are connected and combined to form the support devices of different sizes and specifications. The quantity of the shape-regulating components and positioning plates can be determined according to the size of the skin parts. The device of the invention realizes the flexible clamping and greatly reduces the quantity of special clamps and work pieces so as to reduce cost and coordination links and to shorten preparation period, with distinct economical and time benefits.

Description

(1) Technical field: [0001] The invention relates to a combined flexible multi-point support device for skin profile measurement, which belongs to the field of mechanical engineering / sheet metal forming. (two) background technology: [0002] Aircraft skin parts have complex and diverse shapes and a wide variety of parts, and their surface quality and shape accuracy have an important impact on the overall performance of the aircraft. At present, physical molds are mainly used in skin forming, trimming, and measurement. Therefore, it is necessary to design a physical mold for each skin, resulting in most of the time in the development cycle being spent on the design and manufacture of molds and related tooling. Therefore, the traditional mold tooling and process methods are no longer suitable for the rapid development and batch production of modern aircraft, and the time-saving and efficient flexible multi-point forming technology is gradually applied to factory production. ...
