Abstract
A guiding device for fitting a solid engine mandrel comprises a guide block and a guide bar. One end of the guide block is connected with a main mandrel, and the other end of the guide block is connected with the guide bar. The outer peripheral surface of the guide block is stepped. The end, connected with the main mandrel, of the guide block is a constant diameter segment. The outer periphery of the constant diameter segment is provided with a threaded surface fitting an internal threaded hole of the main mandrel. The end, connected with the guide bar, of the guide block is provided with a conical outer peripheral surface providing convenience of guiding. The middle of the guide block is another constant diameter segment, the outer diameter of the constant diameter segment is slightly larger than that of the main mandrel, and accordingly the main mandrel can penetrate the head of a housing smoothly and conveniently. The guiding device has the advantages that the problem that the head of the main mandrel penetrates the head of the housing difficultly when the main mandrel is mounted in mandrel fitting is solved, damage of a housing covering liner and an insulation layer likely from the head of the main mandrel during the fitting process is avoided, and the guiding device is simple and reliable to apply in practice and convenient to operate. Through the application of the guiding device, rate of damage of the insulation layer of the housing from the main mandrel is reduced from the original 10% to 0.
Description
Technical field
The invention belongs to Solid Rocket Motor Technology field, relate to a kind of guider for the assembling of solid engines core.
Background technology
During the assembling of solid propellant rocket core, need to first main plug be inserted from housing afterbody, main plug lower end passes from housing head, contacts closely with head opening, is difficult for passing.Therefore need core assembling guider to guide main plug to pass from coated housing head opening.
During existing engine core assembling, use crane that main plug is inserted from housing afterbody, main plug lower end passes from housing head opening again, and main plug lower end and coated housing head opening size approach, in operating process, be difficult for main plug to pass smoothly, if Disalignment or careless manipulation, damage will be caused to lining and the heat insulation layer of coated housing in main plug lower end, affects product quality.Through retrieval, find no the technology similar to the present invention.
Summary of the invention
For overcoming the hidden danger of quality existing in prior art, and when core assembles convenient operation, the present invention proposes a kind of guider for solid engines core assembling.
The present invention includes guide pad and guide post.One end of described guide pad is connected with main plug, and the other end is connected with guide post.Described guide pad external peripheral surface is stepped, is wherein isometrical section with main plug link, has the flank coordinating with main mandrel internal-thread hole at this excircle of isometrical section.The external peripheral surface of guide pad and guide post link is taper, and its tapering is 10 °, so that guiding.Described guide pad middle part is isometrical section, and the external diameter of this section is slightly larger than the external diameter of described main plug, is convenient to main plug and from housing head, passes smoothly.
The end face of described guide pad and guide post link has tapped through hole, and the internal diameter of this through hole is identical with the external diameter of guide post.
The operating handle installing hole of uniform symmetry on the circumference at described guide pad middle part.
When core assembles: described guide pad upper external screw thread is connected with main plug head internal thread; Described guide post lower end metal tube passes from housing head at first, play the guiding role, and guide pad and main plug head is guided from motor body head opening, then unload guider, and locking device is installed, and main plug is seated.
During core assembling, first the present invention and main plug head are threaded connection, re-use crane and under the guiding of guider, main plug is passed from housing head opening, complete assembling.
Described guide pad of the present invention and guide post are ordinary steel Q235 and make, and outer surface Passivation Treatment avoids outer surface to get rusty.Being connected of guide pad and guide post, guide pad are connected with main plug head, all use and are threaded, and connect reliably, and easily installation and removal, easy to operate.
Guider of the present invention, when the main plug of core erection, effectively solve main plug head and be difficult for the difficult problem passing from housing head, and avoided the damage that in assembling process, main plug head may cause being coated housing lining and heat insulation layer, simple and reliable, easy to operate in actual applications.By the enforcement of apparatus of the present invention, main plug is reduced to 0 to the damage ratio of case insulation by original 10%.

The specific embodiment
The present embodiment is a kind of guider of solid engines core assembling, comprises guide pad 2 and guide post 3.
Described guide pad 2 is hollow revolving body.One end of this guide pad 2 is for being connected with main plug 1, and the other end is connected with guide post 3.Described guide pad 2 external peripheral surfaces are stepped, are wherein isometrical section with main plug 1 link, have the flank coordinating with main mandrel internal-thread hole at this excircle of isometrical section.At described guide pad middle part, be isometrical section, the external diameter of this section is slightly larger than the external diameter of described main plug 1, is convenient to main plug and from housing head, passes smoothly.On the circumference at described guide pad middle part, be evenly equipped with 2 symmetrical through holes, for fitting operation handle, the dismounting of handled easily personnel to guider, its aperture is greater than handle diameter, convenient operation.Guide pad 2 has tapped through hole with the end face of guide post 3 links, and the internal diameter of this through hole is identical with the external diameter of guide post.Guide pad 2 is taper with the external peripheral surface of guide post 3 links, and its tapering is 10 °, so that guiding.
Described guide post 3 is common metal pipe.The external diameter of guide post 3 is identical with the internal diameter of guide pad 2 link end-face helical through holes.The external peripheral surface of guide post 3 one end has screw thread.
When core assembles, described guide pad 2 upper external screw threads are connected with main plug head internal thread, described in during assembling, guide post 3 lower end metal tubes pass from housing head at first, play the guiding role, guide pad 2 and main plug 1 head are guided from motor body head opening, unload again guider, locking device is installed, main plug is seated.
The present embodiment is by guide pad, guide post by main plug head from housing head opening safe guidance out, convenient disassembly in actual application, easy operating, successful.
