CLAMPING DEVICE DURING REPAIR OF UNITS MADE OF POLYMERIC COMPOSITE MATERIALS Russian patent published in 2025 - IPC F16B47/00 B29C73/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to machine building, particularly, to clamping devices used for clamping glued parts in repair of aircraft components. Proposed device comprises clamping element made up of flexible resilient shell with its bottom resting via repair patch layers on ship surface and its top resting on working chamber. Working chamber consists of central box-like section and several lateral box-like sections, wherein said lateral box-like sections are hinged to said central box-like section. Pressure element union is fitted in pressure element to extend through central box-like section. On the middle box section there installed is a hollow power bushing, outside of which along the perimeter tubular inserts reinforced with stiffeners are fixed. Stiffness ribs are fixed on one side on tubular insert, and on the other side on power bushing. Tubular inserts are connected to side box sections by means of tie-rods by couplings connected in pairs. Inside the tubular inserts on the side opposite to the power bushing the spacers are installed with possibility of the spacer travel inside the tubular insert. Clamps are installed on tubular inserts on the side opposite to power bushing. Spacers at the opposite end from the tubular insert are connected to extension pieces on the ends of which there are perforated plates installed, which are hingedly connected to ball bearings; ball bearings are connected by means of a ball hinge to vacuum suction cups in which nozzles of vacuum suction cups are installed.

EFFECT: providing strength characteristics of repair patch close to autoclave moulding process.
