Problems solved by technology

[0005] ①. Since the current tooling only adopts both ends to support, the middle skin is easily deformed during hole making, which increases the error of hole making
②. Due to the cover of the pressing plate, the coverage rate of the hole making will not reach 100%.
③. Hole making and riveting cannot be carried out on the tooling at the same time
Therefore, there are many problems in the current tooling, which affect work efficiency and quality safety.

Abstract

The invention provides a stringer skin tooling structure which comprises workpiece fixing devices, workpiece positioning devices, fixed beams and a frame body. The fixed beams are vertically arrangedon the frame body; the workpiece fixing devices comprise pincers parts, support parts and sucker parts; the support parts are arranged on the fixed beams and are provided with protruding support platforms; the pincers parts and the sucker parts are arranged on the support parts; the lower pressing ends of the pincers parts can be abutted against the upper end surfaces of the support platforms; theadsorption planes of the sucker parts and the outer end surfaces of the support platforms are co-directional; and the workpiece positioning devices are arranged on side beams and / or cross beams of the frame body and are used for positioning stringers and skins. Through the stringer skin tooling structure provided by the embodiment of the invention, by utilizing two acting forces with opposite directions, the stringer and the skin can fit closely and are not easy to deform, the hole making work can be carried out conveniently, and the hole making coverage rate can be improved.

Description

technical field [0001] The invention relates to the technical field of workpiece assembly, in particular to a long truss skin tooling structure. Background technique [0002] Large panels are widely used in structures such as wings and fuselages. Typically, large siding consists of skin and stringer structures. The girder and the skin are fixed by riveting, so it is very important to be able to complete the hole riveting work accurately, quickly and with high quality. [0003] At present, mechanical wood clamping tooling is mostly used for the hole making of aircraft long trusses. When working, first install the stringer to the calibrated position, and at the same time fix and lock both ends of the stringer; then put the skin close to the stringer, and press the skin with the strip-shaped pressure plates on both sides. After the skin is installed, the hole making and riveting work are carried out to assemble the stringer and the skin as a whole. In addition, the tool nee...
