Problems solved by technology
In the past, there was no special support for the adhesive parts in the preparation process, and the quality of the adhesive parts could not be guaranteed, which easily caused problems such as: slipping and misalignment between layers, uneven bonding, and sticking of adjacent adhesive parts.
At the same time, for different bonding materials and adhesives, it is very important to provide an appropriate pre-tightening pressure during the preparation process, which will determine the final interface performance; however, the pre-tightening pressure cannot be quantified during the preparation of existing adhesive parts Adjustment, unable to control the adhesive performance of adhesive parts

The invention discloses an adhesive preparation device with adjustable pre-tightening force, which comprises a base, a partition plate arranged on the base that can slide along the length direction of the base panel and lock its position, and a partition plate that can be perpendicular to the base panel along the periphery of the base. The pressure plate on which the limit boss slides, and the weight plate arranged on the top of the pressure plate, wherein, the part of the partition board beyond the base panel is smaller than the height of the adhesive parts set between adjacent partition boards, and greater than the height of the adhesive parts. The height of the half. The invention can ensure that no sliding dislocation occurs between the layers of the bonding parts, the bonding pre-tightening pressure can be adjusted according to actual needs, and the bonding is uniform.
Description
technical field [0001] The invention belongs to the technical field of material mechanics research, in particular to an adhesive preparation device with adjustable pretightening force. Background technique [0002] With the continuous development of modern science and technology, bonding structures are more and more used in aerospace, vehicles, ships and other related equipment structures. Compared with traditional connection methods such as welding, screw connection, riveting, etc., the use of adhesive structure can well avoid problems such as stress concentration and damage to the adhered material. [0003] There are a large number of laminated bonded components in engineering, among which the bonding performance of the interface is particularly important for the stability of laminated bonded components. In the past, there was no special support for the bonding parts in the preparation process, and the quality of the bonding parts could not be guaranteed, which easily cau...
