Adhesive jig and method

Abstract

The invention discloses a glue joint clamp. The clamp comprises a rack, a pressure application mechanism and a clamping mechanism. A mounting groove is formed in the top face of the rack in a penetrating manner in the thickness direction; the clamping mechanism comprises a main clamp body and an auxiliary clamp body, a baffle is arranged on the top of the auxiliary clamp body, the auxiliary clampbody is detachably connected into the rack, the baffle can extends out of the mounting groove, the main clamp body is arranged on the rack, and located outside the auxiliary clamp body and can move inthe length and height direction of the rack relative to the auxiliary clamp body, the pressure application mechanism is connected to the upper portion of the support, a pair of plates to be cementedare placed on the top face of the rack, and are clamped through the clamping mechanism, and pressure is applied through the pressure application mechanism. During use, a test part is placed on the rack, through the relative motion of the main clamp body and the auxiliary clamp body, positioning and clamping of test parts are finished, through the motion of the pressure application mechanism, the pressure is applied to the test part, the opposite width and the opposite height between the main clamp body and the auxiliary clamp body can be adjustable, the clamp can be suitable for test parts with various different sizes, and the application range is wide.

Description

technical field [0001] The invention belongs to the field of bonding, and in particular relates to a bonding fixture and method. Background technique [0002] Adhesive bonding is a process method that uses adhesives to produce mechanical bonding force, physical adsorption force and chemical bonding force on the connection surface to make two parts to be connected firmly connected. The bonding process is simple, and the joint is not easily deformed. It is suitable for the connection of the same or different metal materials or composite materials. With the vigorous development of lightweight design in industry, the application of bonding structures is becoming more and more extensive. Aerospace and other fields occupy a very important position. For example, considering factors such as economy and environmental protection, modern aircraft adopt glued structures in fuselage, wings and other parts. Glued single lap joint is the most commonly used joint form in metal bonding, and...

Problems solved by technology

[0003] However, the current fixtures for curing adhesive joints have certain limitations: (1) the clamping size is single and cannot adapt to adhesive joints of different sizes; (2) most adhesive joint fixtures can only fix a single adhesive joint at a time, resulting in processing Low efficiency; (3) The controllability of the fixing pressure of the fixture is poor, and the glued parts need to be baked and solidified at a higher temperature, and it is difficult to accurately control the fixing pressure with a pressure detection device
