The invention discloses an automatic bonding mechanism and method for a heat insulation
rubber sheet of an inner
conical surface of a
solid rocket nozzle, and belongs to the technical field of engine
nozzle assembly manufacturing. The bonding structure comprises a base, a supporting plate, a
silica gel suction cup, a rotating mechanism, a flat pressing plate, a guide mechanism and a
servo electric cylinder. One side of the flat pressing plate is connected with a guide mechanism which drives the flat pressing plate to move up and down. The rotating mechanism is perpendicular to the flat pressing plate, the upper surface of the rotating mechanism is connected with the lower surface of the flat pressing plate, the end of the rotating mechanism is connected with the
silica gel suction cup, and the
silica gel suction cup is driven to rotate through rotation of the end to achieve vertical overturning of the silica gel suction cup. The silica gel suction cup is located over the spraying
pipe, the upper surface of the silica gel suction cup is a
conical surface coated with silica gel, and the heat insulation rubber is adsorbed to the silica gel. And the
servo electric cylinder downwards pressurizes the rotating mechanism, so that the heat insulation rubber is adhered to the inner
conical surface of the spray
pipe. Through the application of the device, adsorption
pickup,
desorption placement, automatic exhaust and pressure forming of the rubber are realized, and the bonding efficiency and reliability are improved.
