Description
Technical field
The present invention relates to a kind of assembly tools more particularly to a kind of adjustable jet pipe of multiple degrees of freedom to assemble device.
Background technique
Jet pipe assembly is an important ring in solid propellant rocket general assembly work, one of currently used jet pipe assembly method
It is to be fixed on fixation rocket engine to be installed on jet pipe assembly device, jet pipe is hung to solid engines shell with suspender
Inside tentatively cooperate with solid rocket motor case, then by jet pipe assembly device jet pipe precisely pushed to rigging position into
Row installation is fixed, and jet pipe assembly precision directly influences solid propellant rocket normal use, therefore during jet pipe push
Need to guarantee the concentricity of jet pipe and solid rocket motor case；Jet pipe material protects material using frangible nonmetal heating simultaneously
Material easily produces jet pipe nonmetal heating protective materials if the thrust of jet pipe assembly device push jet pipe is intersected with nozzle axis generation
Raw damage, influences the service performance of jet pipe；Different Dimension of Solid Rocket Motor are not quite similar, jet pipe rigging position (such as fulcrum
Position, assembly height, conduct etc.) it is different, it is special need to specially to design outfit for each engine model in previous assembly work
Some jet pipes assemble device, not only increase cost in this way, also create managerial difficulty.It needs to devise one kind in summary
The adjustable jet pipe of multiple degrees of freedom assembles device, with guarantee jet pipe in assembly push with solid rocket motor case concentricity,
The jet pipe assembly generalization of different model solid propellant rocket is realized simultaneously.
Summary of the invention
The technical problem to be solved by the present invention is to guarantee jet pipe in assembling process with solid rocket motor case
Concentricity, while the jet pipe of different model solid propellant rocket assembles generalization, provides a kind of adjustable jet pipe of multiple degrees of freedom
Assemble device.

Thrust block pad is realized in solid propellant rocket tail portion vertical by adjusting the adjusting of vertical plate I in the vertical direction
The upper transposition section in direction ensure that installed thrust solid propellant rocket and install the concentricity of jet pipe.
Two parallel horizontal through slots are set on the workbench, and the arc frame is used to support solid-rocket and starts
Machine, arc frame pass through horizontal through slot by bolt with workbench and realize that bolt is fixedly connected, logical in level by adjusting bolt
Position in slot realizes the displacement of arc frame on workbench in the horizontal direction and adjusts, and adapts to different solid propellant rockets
The variation that position of the fulcrum and support width require.
The adjusting vertical plate II is placed in solid propellant rocket front end, for fixing the fixation of rocket engine horizontal direction
Limit adjusts vertical plate II with workbench and realizes that bolt is fixedly connected across horizontal through slot by bolt, existed by adjusting bolt
Position in horizontal through slot, which realizes, adjusts the displacement adjusting of vertical plate II on workbench in the horizontal direction, adapts to different length
The fixed limit of the solid propellant rocket of size in the horizontal direction, has been achieved solid propellant rocket in the horizontal direction
On displacement adjust.
Level board is fixedly mounted in the middle part of support frame as described above, threaded rod extends vertically through level board and is threadedly coupled with level board,
Threaded rod bottom end is fixedly connected with support base, and threaded rod tip is fixedly connected with rocking handle, turns threaded rod by rotation crank in this way
It is dynamic realize workbench adjustings is raised and lowered, both realized the displacement of solid propellant rocket integrally in vertical direction
It adjusts.
For the property easy to use for promoting apparatus of the present invention, brake sheave is installed in the support frame bottom.
To remain vertical direction when guaranteeing that scale plate is displaced adjusting in the vertical direction, on scale plate surface edge
Slide rail is set on vertical direction, adjusts vertical plate I and slide rail is cooperatively connected, this ensure that adjusting the adjusting of vertical plate I
Always the adjusting of vertical direction is maintained at along slide rail.
Convenient for disassembly and assembly for convenience of arc frame, the material of arc frame selects pine, and Pine surface is bonded felt.
Since the harness of fraction solids rocket engine is connected outward across jet pipe, to avoid jet pipe from pushing
Harness will not be clipped in the assembly essence in the assembly gap of jet pipe and solid rocket motor case and influencing jet pipe in the process
Degree, therefore skewed slot is set in the end that thrust block pad is contacted with jet pipe, harness is drawn from jet pipe by skewed slot, is reduced
Surplus length of the fiery conducting wire in jet pipe and solid rocket motor case.
The beneficial effects of the present invention are: the configuration of the present invention is simple, by the horizontal direction, in vertical direction and supporting point
Adjusting, ensure that jet pipe concentricity with solid rocket motor case in push assembling process, realize different solids
The jet pipe assembly generalization work of rocket engine, had both saved the cost of the jet pipe assembly device of different model, had also improved
Criticize the working efficiency of production solid propellant rocket.
