Embodiment Construction

[0039] The present invention is a combined flexible multi-point support device for trimming of skin profiles, which adopts modular design ideas, such as figure 1 As shown, it is composed of several positioning plates 2, several shape-adjusting assemblies 17 composed of base pillows 3 and nail height adjustment units 4.

[0040] Such as figure 2 , image 3 , Figure 4 Middle: the shape-adjusting component 17 is placed horizontally, and the positioning plate 2 is placed vertically.

[0041] The positioning plate 2 is a flat "T" shape, on which a threaded hole and a mating surface 20 are provided.

[0042] Such as Figure 5 As shown, the shape adjusting assembly 17 is composed of the base pillow 3 and the nail height adjusting unit 4 .

[0043] The base pillow 3 is a cuboid, on which there are positioning holes 18, threaded holes, mating surfaces and the like. Five positioning holes are evenly distributed in a line on the base pillow, and the nail height adjustment units 4...

Abstract

The invention relates to a combination flexible multipoint support device with skin and trimming, which consists of a plurality of positioning plates and a plurality of adjusting components; the positioning plates is flat T-shape and a threaded hole and a matching surface are arranged on the positioning plates; the adjusting components consist of a basioccipital and a nail height adjusting unit; the adjusting components are put in parallel in an X direction and the interval between centers is fixed; the positioning plates are divided into two symmetrical rows in a Y direction; each positioningplate is connected with the same end of two adjacent adjusting components; the basioccipital shapes like a rectangular and locating holes, a threaded hole and a matching surface are arranged on the basioccipital; the locating holes are evenly distributed in a line on the basioccipital and the nail height adjusting unit is fixed in the locating holes; the nail height adjusting unit consists of a large double-screw bolt, a bolt, a locknut, a rotary nail, a replaceable nail sleeve, a joint cylinder, a universal device, a vacuum generator and a vacuum chuck. The device of the invention realizes flexible holding, reduces special clamping devices and frocks and has remarkable economic and time benefits.

Description

(1) Technical field: [0001] The invention relates to a combined flexible multi-point support device for edge trimming of a skin profile, 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, solid molds are mainly used in skin forming, trimming, and measurement. Therefore, it is necessary to design a solid 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. ...
