Problems solved by technology

[0002] Nowadays, soft connections are often used to connect the cockpit glass and the cockpit frame. Polyurethane adhesives are generally used to bond glass and polyester tapes. Polyurethane adhesives have strict pressure restrictions during the bonding process, so the pressure of the tooling fixture is too large or too high. A small amount will cause the bonded parts to fail to meet the quality requirements

Abstract

The invention relates to a constant-force pressing device for organic glass bonding. The constant-force pressing device is composed of a constant-force clamp and an installing pincer. The constant-force clamp is composed of two supports arranged up and down, the middles of the two supports are connected through a rotating shaft, a sleeve is arranged at the end of one support, a pin shaft penetrates through an inner cavity of the sleeve, the two ends of the pin shaft are movably connected with the corresponding supports, a spring is coaxially arranged on the sleeve, one end of the spring is limited on the surface of one support through a washer, and the other end of the spring is limited on the surface of the other support through a washer; the outer ends of the two supports are jointly connected with the installing pincer, and the installing pincer and the spring are located at the same-side ends of the supports. The constant-force pressing device is stable in pressure and stable and reliable in bonding quality; by means of the bonding method, operation efficiency is improved, and product quality is improved.

Description

technical field [0001] The invention relates to a constant force pressing device and method for plexiglass bonding, belonging to a tooling fixture. Background technique [0002] Nowadays, soft connections are often used to connect the cockpit glass and the cockpit frame. Polyurethane adhesives are generally used to bond glass and polyester tapes. Polyurethane adhesives have strict pressure restrictions during the bonding process, so the pressure of the tooling fixture is too large or too high. A small amount will cause the bonded parts to fail to meet the quality requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a constant force pressing device and method for plexiglass bonding. The pressure of the device is stable, and the bonding quality is stable and reliable. The bonding method improves work efficiency and product quality . [0004] In order to solve the above problems, the specific technical so...
