Description
Technical field
The present invention relates to a kind of solid propellant rocket manufacturing technology, be specifically related to machine mouth grouting work after a kind of solid propellant rocket
Dress.
Background technology
Solid-rocket starts just (model XX-68A) forward and backward artificial unsticking seam domestic demand to pour into grouting material, plays thermal insulation and release
Stress etc. act on, it is desirable to artificial unsticking gap is full of, fills real by grouting material.
At present, behind XX-68A combustion chamber, the grouting of machine mouth uses horizontal grouting.Existing grouting process requires " should first use F410-1 before grouting
Artificial unsticking gap is blocked by joint filling material, and closure scope should be greater than the 1/3 of machine mouth arc length, joint filling material solidification 2h with
After on, the two ends plasticine at joint filling material respectively does a funnel-form chute.During grouting, grouting material is filled by a chute from which
Enter in artificial unsticking seam, after seeing liquid level from another chute, stop grouting ".Because grouting material has poor fluidity, foaming etc.
Physical attribute, therefore during practical operation, there are the following problems: 1. because artificial unsticking seam gap is narrow, grouting material mobility
Difference, the material once poured into are few, cause every product to be both needed to repeatedly batch mixing grouting and just can complete this operation, inefficiency；②
Because of the grouting material foaming in pouring into artificial unsticking seam, bubble is difficult to discharge, and after grouting material solidifies, operating personnel cannot
Filling reality degree in stitching artificial unsticking judges, it is possible to exists and fills unreal or leakage filling phenomenon, affects product quality reliability.
Therefore, the existing grouting process grouting cycle is long, easily occurs filling unreal problem, and personnel also cannot be to the filling in artificial unsticking seam
Slurry situation carries out checking confirmation, replaces plugging grouting method by plasticine barrier dam technology, although shorten the grouting cycle and fill unreal
Quality problems, but barrier dam process is relatively complicated, takes time and effort, inefficiency.
Summary of the invention
In view of the problem in the presence of above-mentioned prior art, the present invention provides machine mouth grouting frock after a kind of solid propellant rocket,
Solve the grouting cycle longer and fill unreal problem, and improve operating efficiency.
The concrete technical scheme of the present invention is as follows:
A kind of solid propellant rocket tail machine mouth grouting frock, including Internal baffle, outer baffle, top board, upper connecting rod, lower link I
With lower link II, the molding surface size that wherein top board and outer baffle require according to the nonmetal step of machine mouth after solid propellant rocket is carried out
Design；Internal baffle is according to machine mouth reshaping structure size design after solid propellant rocket；Upper connecting rod passes through adjusting nut and lower link
I is assembled integrally, and is connected with Internal baffle, top board, applies pressure by adjusting nut to Internal baffle；Upper connecting rod is by regulation spiral shell
Mother is assembled integrally with lower link II, applies pressure by adjusting nut to outer baffle.
The uniform multiple screws of outer baffle, for being connected with machine mouth lower end after solid propellant rocket；Six screws are had respectively on top board,
Wherein 3 is screw hole I, and 2 is screw hole II, and 1 is screw hole II I, and after screw hole I and solid propellant rocket, machine mouth upper end is fixed,
Screw hole II is for the fixing upper connecting rod being connected with Internal baffle, and screw hole II I in the middle part of top board is for the fixing upper connecting rod being connected with outer baffle.
For making this grouting frock fit tightly with nonmetal step surface and powder column shaping surface, inside and outside baffle plate and upper connecting rod, lower link
I and lower connecting rod II junction are respectively equipped with sealing gasket and O RunddichtringO.
The invention have the benefit that the use of this frock can shorten grouting time, solve unreal problem of being in the milk, save
Cost, shortens the grouting cycle, and batch product for subsequent models lays the foundation.

Detailed description of the invention
Describe the present invention with instantiation below in conjunction with the accompanying drawings.
The molding surface size required according to the nonmetal step of machine mouth after XX-68A solid propellant rocket, design top board 1 and outer baffle
11.The key dimension of top board 1 and outer baffle 11 includes the degree of depth of diameter and step, and to design outer baffle radian be 120 °.
According to machine mouth reshaping structure size after the multiple XX-68A Solid Rocket Motor combustion chamber of statistics, designing Internal baffle 10, radian is
120°.Uniform 5 screws of outer baffle 11, for being connected with rear machine mouth lower end, with fixing outer baffle 11.On Internal baffle 10
Reserved 4 screw hole II of end, for fixing with lower link I 8.Have respectively on top board 1 six screws (3 screw hole I, 2
Screw hole II, 1 screw hole II I), wherein screw hole I is fixed with rear machine mouth upper end, and screw hole II is connected with Internal baffle 10 for fixing
Upper connecting rod 6, screw hole II I in the middle part of top board 1 is for the fixing upper connecting rod 6 being connected with outer baffle 11.Internal baffle 10, outer baffle 11
