Problems solved by technology

[0004] The vacuum bag pressure method can only adjust the pressure by adjusting the curing parameters. During the test stage, multiple curings are required to obtain the required curing parameters. The test cost is high, and the pressure exerted on the parts cannot be known by mechanical pressure. high pressure uncertainty

Abstract

The invention provides an accurate pressurizing gluing clamp. The clamp is based on a lever principle, is provided with a connecting rod mechanism, realizes the adjustment of gluing pressure by adjusting the weight of a balancing weight and the hanging position of the balancing weight, can simultaneously glue a plurality of groups of test pieces 8 by reasonably arranging the structure of a pressurizing mechanism, enables the structure to be bilaterally symmetrical, balances the whole gravity center and avoids overturning. The part in contact with the test pieces 8 is made of an aluminum alloymaterial and is coated with demolding cloth, so that the test pieces 8 are conveniently demolded. According to the invention, the problems that the test pieces 8 are low in qualification rate in the test stage and the quality cannot be ensured are solved, the most suitable curing parameters and pressure are obtained through a comparison test in a short time, and the gluing quality, the productionefficiency and the product stability of the test pieces 8 are ensured.

Description

technical field [0001] The invention belongs to the metal bonding forming technology, and relates to a precise pressure bonding fixture. Background technique [0002] Domestic models of helicopter floors and other components mostly use metal adhesive parts due to stress concentration caused by no drilling holes, light structure, and high connection efficiency. Curing under temperature and pressure. [0003] At present, the metal bonding parts of domestic models mostly adopt the vacuum bag pressure method, that is, vacuuming in the vacuum bag, maintaining atmospheric pressure in the autoclave, causing the pressure difference between the inside and outside of the vacuum bag to pressurize the bonding parts, or pressing the clamp mechanically. In this way, the parts are pressurized by compressing the pinch point and transmitting the pressure of the pressure plate. [0004] The vacuum bag pressure method can only adjust the pressure by adjusting the curing parameters. During th...
