Multifunctional butt joint device for double-pulse engine

Abstract

The invention provides a multifunctional butt joint device for a double-pulse engine. The device comprises a frame, a lifting mechanism, hoop assemblies, a pressing device, a transverse moving mechanism and a supporting guide rail, wherein the supporting guide rail is arranged on the frame, and the lifting mechanism can move along the supporting guide rail; the hoop assemblies are arranged on thelifting mechanism through the transverse moving mechanism and horizontally moves in a manner of being perpendicular to the supporting guide rail, and rolling wheels are arranged on the hoop assembliesto drive the engine arranged on the hoop assemblies to rotate in the axial direction of the engine; and at least two hoops are used for fixing one stage of engine body, the two stages of engine bodies are adjusted to be coaxial with each other through the lifting mechanism and the transverse moving mechanism, and the pressing device adjusted to be coaxial with the engine is used for pushing the two stages of engine bodies to be in butt joint with each other. According to the device, the butt joint precision is high, the rapid movement is achieved, the rapid butt joint is achieved, the labor intensity is reduced, the utilization rate of the device is high, the cost is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of double-pulse rocket motor assembly. Background technique [0002] At present, the dual-pulse engine adopts two-stage engines, which require a certain operating distance between the first and second engines; the first-stage engine and the second-stage engine are sealed by sealing rings, and due to the structural characteristics of the engine itself, there is no process positioning hole in the docking part. The docking accuracy is high; after the docking is completed, the primary and secondary engines are connected by screws, and the screws have torque requirements. The engines are required to be able to rotate after docking, so as to ensure that the torque of each screw is in place and the product quality is guaranteed. [0003] Currently, two-stage engines are docked on a docking device that needs to provide adjustment in three degrees of freedom. The docking device is composed of a plurality of support ...

AI Technical Summary

Problems solved by technology

[0004] Now there are problems with the docking device: (1) The horizontal adjustment mechanism and the vertical adjustment mechanism are adjusted by the screw. For the engine with a relatively large weight, the adjustment of the screw is laborious; (2) The engine cannot rotate in the support ring and needs to be hoisted. , increased labor intensity and working hours, and greatly reduced production efficiency; (3) The engine support ring cannot be replaced and cannot be used for other types of double-pulse engines, and the docking device has poor versatility, which is not conducive to reducing production costs; (4) Butt docking The device adopts an integral structure, and the parts cannot be disassembled, which leads to difficulty in loading, and does not use the transfer factory for transportation, which increases the labor intensity of the operator; (5) the supporting components of the existing docking device slide on the pit track, and for heavy Engine, human propulsion is more difficult
