It is fixed to connect.
Thrust block pad is realized in solid propellant rocket afterbody by adjusting the regulation of riser I in the vertical directions
Displacement in vertical direction is adjusted, it is ensured that installed thrust solid propellant rocket and the axiality for installing jet pipe.
Two parallel horizontal grooves are set on the work platformses, and the arc frame is used to support solid-rocket
Through horizontal groove, electromotor, arc frame realize that bolt is fixedly connected by bolt with work platformses, by adjusting
Position of the section bolt in horizontal groove realizes arc frame displacement on work platformses in the horizontal direction and adjusts
Section, adapts to the change that different solid propellant rocket position of the fulcrum and support width are required.
The regulation riser II is placed in solid propellant rocket front end, for fixing rocket engine horizontal direction
Fixation it is spacing, adjust riser II realize that bolt be fixedly connected through horizontal groove by bolt with work platformses,
By position of the regulating bolt in horizontal groove realize regulation riser II on work platformses in the horizontal direction
Displacement adjust, the solid propellant rocket fixation in the horizontal direction for adapting to different length size is spacing,
It has been achieved in that solid propellant rocket displacement in the horizontal direction is adjusted.
Fixedly mount horizontal plate in the middle part of support frame as described above, threaded rod extend vertically through horizontal plate and with horizontal plate screw thread
Connection, threaded rod bottom are fixedly connected support base, and threaded rod top is fixedly connected rocking handle, so by turning
Shake handle make threaded rod rotate realize work platformses regulations is raised and lowered, both realized solid-rocket
The overall displacement in vertical direction of motivation is adjusted.
To lift the property easy to use of apparatus of the present invention, brake sheave is installed in described bracing frame bottom.
To ensure to remain vertical direction when the displacement of graduated tile in the vertical direction is adjusted, in the graduated tile
Surface is vertically upper to arrange rail plate, adjusts riser I and is connected with rail plate, so ensures
The regulation for adjusting riser I is maintained at the regulation of vertical direction all the time along rail plate.
For convenience of arc frame easy accessibility, the material of arc frame selects Masson Pine, Pine surface bonding felt.
As the harness of fraction solids rocket engine is outwards connected through jet pipe, to avoid jet pipe
Shadow during harness will not be clipped in the assembling gap of jet pipe and solid rocket motor case during push
The assembly precision of jet pipe is rung, therefore the end setting skewed slot contacted with jet pipe in thrust block pad, by skewed slot by point
Fiery wire is drawn from jet pipe, reduces surplus of the fiery wire in jet pipe with solid rocket motor case long
Degree.
The invention has the beneficial effects as follows：Present configuration is simple, by the horizontal direction, in vertical direction with
And the regulation of the strong point, it is ensured that jet pipe is coaxial with solid rocket motor case in assembling process is pushed
Degree, realizes the jet pipe assembling generalization work of different solid propellant rockets, had both saved different model
Jet pipe assembles the cost of device, also improves batch work efficiency of production solid propellant rocket.
