Problems solved by technology

This assembly method is cumbersome when replacing products with different diameters. It is necessary to carefully adjust the centering again. Small differences will cause uneven force on the arrow body. It must rely on the precision track system in the factory building, and it cannot be used in field battles outside the building. Safe and reliable disassembly and assembly

Embodiment 1

[0037] The airbag-type flexible docking is installed vertically, taking the installation of the rocket body and the engine nozzle assembly as an example.

[0038] The assembly workshop needs to set up a crane and a special base centering platform. The crane is responsible for the vertical transfer of the main body. The base centering platform is equipped with a small displacement lifting platform, which is equipped with a multi-chamber airbag. The upper part of the airbag can be wound around the vertical axis. Free-rotating support plate for fixed nozzles.

[0039] First fix the nozzle on the base support plate, then pressurize the airbag and level it; hang the main body vertically at a height of 20cm above the nozzle centering platform; slowly raise the nozzle support plate of the centering platform, Coaxial positioning is carried out by means of positioning pins; after the connecting end faces of the main body and the nozzle are basically in contact, the screws are sequentia...

Embodiment 2

[0041] The air cushion platform is docked and installed vertically, taking the installation of the rocket body and the engine nozzle assembly as an example.

[0042] A further improvement is to replace the multi-chamber airbags of the centering table with an air cushion platform and a three-axis fine-tuning platform, and the centering process is completely completed by electromechanical force. The use of a flat air cushion can cause almost no horizontal resistance when the nozzle is centered, and minimize the stress on the screw holes and through holes during the centering process. But the premise of using this method is to ensure that the air cushion plane of the platform is perpendicular to the axis of the rocket body.

[0043] The specific operation steps are: first pass compressed air to the air cushion table, place the air cushion table in the center of the three-axis fine-tuning platform table, and then cut off the air; place the nozzle on the top of the air cushion tabl...

Abstract

The invention discloses a vertical assembling flexible butt joint structure and method for medium and large rockets. The vertical assembling flexible butt joint structure comprises a moving mechanism, a lifting mechanism and a flexible platform. The lifting mechanism is arranged on the moving mechanism, the flexible platform is arranged on the lifting mechanism, and a rocket nozzle is placed on the flexible platform. The flexible platform is an air cushion bedplate or air bag assembly, and the rocket nozzle is arranged on the air cushion bedplate or air bag assembly. The vertical assembling flexible butt joint structure is reliable in safety, the stress caused to a connecting piece in the centering process can be reduced to the maximum degree through flexible centering, and the centering precision can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing solid rocket motors, and in particular relates to a flexible docking structure and method for vertical assembly of medium and large rockets. Background technique [0002] Due to their large weight, medium and large rockets used to be assembled using a specially designed precision assembly platform for the main body bracket. The main body bracket assembly platform contains a number of separate track-type trolleys, which can move along precise tracks. Above the trolley, there is a The upper and lower fine-tuning mechanism, the driving wheel and the driven wheel jointly support the main body; the rotation of the driving wheel can make the main body rotate clockwise or counterclockwise, which is convenient for centering when assembling holes; the driven wheel can be radially fine-tuned to facilitate the driving wheel and driven wheel The rubber rollers on the outer edge are in full contact with ...
