Description
Technical field
The present invention relates to a kind of auxiliary mould of solid rocket motor liner shaping, it is adaptable to certain model motor body
Lining shaping.
Background technology
The work step that solid propellant rocket has to completion before powder charge is the lining shaping work of interior engine surface.Lining
Layer is also clad, is one layer of elastomeric material being molded in Solid Rocket Motor combustion chamber shell wall and combustion chamber between propellant
Coating.The effect of lining is propellant and heat insulation layer or combustion chamber shell wall is had a good adhesive property, and limited combustion, heat-insulated
And the effect of buffering stress, analysis has certain elasticity on mechanics, can absorb shaking for part in engine working process
Kinetic energy.In the housing set-up procedure of whole motor charge, all size motor body will pass through the lining of inner surface
Shaping could enter the cast process of propellant.The quality of motor body inwall lining shaping is directly connected to propellant
With the adhesive property of motor body inwall, it can further determine that can engine contemplate the normal work of completion as expected.
Production model before certain model motor body is lining shaping → powder charge → housing outer surface spray painting, due to examining
Influence of the medicine to the safety problem brought during housing outer surface spray painting operation and to case weight is considered, now by engine shell
The production model of body is changed to housing outer surface spray painting → lining shaping → powder charge, and the pattern avoids band medicine housing and enters other
Produce the potential safety hazard that work step is present.But the change of production model is also brought while bring benefit to whole production process
Some problems.For lining shaping step, there is paint spraying tooling to lining in the housing that outer surface completes spray painting in the work step
The influence of operations for forming.Due to not painting, housing can not have been applied in spray painting housing in frock used in lining shaping step
In lining shaping, in order to normally complete the lining shaping work of outer surface spray painting housing, need badly and start for model spray painting
A kind of machine housing design frock ensures the normal operation of housing.
The country has no that association area state-of-the-art technology reports that, due to technical know-how, external correlation technique has no report.
The content of the invention
To solve the deficiency without suitable frock in the lining shaping of spray painting housing, the present invention proposes a kind of solid-rocket and started
The forming frock of machine lining.
The present invention includes connecting plate and connecting rod, and the end face of the connecting rod one end is fixed on the table of the connecting plate
Face.
The geometric center of the connecting plate has through hole, and the spiral shell for connecting the connecting rod is evenly equipped with the periphery of the through hole
Hole.The diameter of section flange is identical between the length of the connecting plate and the machine of engine paint spraying tooling, and two of the connecting plate
Short side is arc-shaped side, and the radius of section flange is identical between the radius of curvature of the arc-shaped side and engine Spray Painter installation.
There is screw respectively on two short sides of the connecting plate, for the connecting plate to be fixed on into section between engine Spray Painter installation
Flange face on.
The two ends end face of the connecting rod has ring flange respectively, and by the ring flange, one end of the connecting rod is fixed on
On the connecting plate, the other end of the connecting rod is connected with driving the universal connecting shaft of housing into rotation.
The present invention solves former lining forming frock that certain model motor body brought due to the influence of paint spraying tooling not
The problem of being applicable, it is ensured that spray painting housing lining shaping work is smoothed out.The present invention is simple in construction, easy for installation, is applicable
Property is strong.

Embodiment
The present embodiment is the frock painted for certain model used in the lining forming process of motor body.The frock
Including connecting plate 2 and connecting rod 1, and the end face of the connecting rod one end is fixed on the surface of the connecting plate by flange.
The connecting plate 2 is rectangle plate.There is through hole in the geometric center of the connecting plate, be evenly equipped with the periphery of the through hole
Screw for connecting the connecting rod.The diameter phase of section flange between the length of the connecting plate and the machine of engine paint spraying tooling
Together, and two short sides of the connecting plate are arc-shaped side, the radius of curvature of the arc-shaped side is installed with the engine Spray Painter
Between section flange radius it is identical.There is screw respectively on two short sides of the connecting plate, for the connecting plate to be fixed on into institute
State engine Spray Painter installation between section flange face on.
The connecting rod 1 is hollow revolving body.There is ring flange respectively in the two ends end face of the connecting rod, pass through the flange
Disk, one end of the connecting rod is fixed on the connecting plate, by the other end of the connecting rod with driving the universal of housing into rotation
Connecting shaft is connected.
In the present embodiment, the profile of the connecting plate 2 is in I-shaped, to mitigate its weight to greatest extent.The connection
The maximum length of plate is 1250mm, and width is 420mm.6 screws, each screw are evenly equipped with the garden periphery of geometric center through hole
Aperture and pitch of holes be adapted with the aperture of the screw in connecting rod end flange and pitch of holes.
Respectively there is a diameter of φ 100mm ring flange at the two ends of the connecting rod, and one of ring flange is with being connected
Plate is connected, and another ring flange drives the universal connecting shaft of housing rotation to be connected in being molded with lining.The length of connecting rod is by shell
Body placement location in operation process is determined；In the present embodiment, the length of the connecting rod is 1500mm.
When using：
The ring flange center of connecting rod one end in lining forming frock and the center of connecting plate are fitted, position is adjusted
Put, each connecting hole on connecting rod ring flange is aligned respectively with each connecting hole on connecting plate, by bolt by connecting rod with
Connecting plate is connected.
The paint spraying tooling mating surface of connecting plate in lining forming frock and the housing that paints is fitted, adjustment position makes company
Each connecting hole at fishplate bar transverse direction face two ends is corresponding with each screw of the flange face of section between Spray Painter's installation；It will be connected by bolt
Plate is connected with paint spraying tooling, whole lining forming frock is just connected with spray painting housing.
By the flange surface of the connecting rod other end with driving the dress that spray painting housing rotates in lining forming process
Put --- the mating surface of universal connecting shaft is connected by bolt.After connection, housing is just normally entered in lining operations for forming process.
