The invention discloses a pressing and curing clamp for adhesive samples. The pressing and curing clamp comprises a fixed clamp body and a movable clamp body. The fixed clamp body comprises a supportplate and a guide plate, wherein one end of the guide plate is fixedly connected with the support plate, and a multi-step pressure adjusting groove is formed in the guide plate from the non-fixed endto the fixed end. The movable clamp body comprises a pressing plate, a push plate, an elastic component and a pressure adjusting component, wherein one end of the elastic component is connected with the pressing plate, the other end of the elastic component is connected with the push plate, and the pressure adjusting component is arranged on the push plate and can be inserted in each step of the pressure adjusting groove. The fixed clamp body and the movable clamp body are disposed left and right, and move oppositely in the horizontal direction to provide curing pressure, the influence of deadweight of the clamp is avoided, and the error of curing pressure is reduced; by inserting the pressure adjusting component to the corresponding step of the pressure adjusting groove, the curing pressure can be kept, that is, grading adjustment of the curing pressure is achieved through cooperation of the pressure adjusting component and the pressure adjusting groove; and it is ensured that the curing pressure applied in the curing process is accurate and controllable, and the adhesion effect is improved.
Description
technical field [0001] The invention belongs to the field of sample bonding, and in particular relates to a fixture and method for bonding samples under pressure and curing. Background technique [0002] Lightweight design is the goal pursued by modern aviation industry and automobile industry. In addition to widely using lightweight materials such as aluminum and magnesium to reduce the weight of the car body or aircraft body, the use of glue instead of traditional welding and riveting to achieve reliable connections between different parts is also an effective way to reduce the weight of the car (machine) body. important means. [0003] Bonding is a method of firmly connecting the same or different materials together by means of the adhesive force produced by an adhesive on a solid surface. Bonding can effectively prevent electrochemical corrosion between different metals because it does not require prefabricated connection holes and stress concentration on the non-hole ...
