Description

A kind of compact lining coating equipment
Technical field
The invention belongs to solid engines lining manufacturing technology fields, are specifically related to a kind of lining spraying equipment.
Background technique
Lining is one of the structure member in Solid Rocket Motor combustion chamber, be located at heat insulation layer and propellant charge it Between, with a thickness of the bonding effect between 0.3mm ~ 1.0mm, primarily serving heat insulation layer and propellant.Lining is a kind of polyurethanes High molecular material, is high-viscosity adhesive before solidification, and poor fluidity becomes elastomeric material after solidification.Lining moulding process packet It includes, prepares slurry, in insulation layer surface coating, precuring and powder charge solidify with propellant before powder charge.Lining Coating process is currently used centrifuging process, by hand blade coating, high pressure solvent spraying and mechanical blade coating.Exist for manual method Lining local thickness quality problems out of control, have an adverse effect to the bonding quality of heat insulation layer and propellant, and production efficiency is low, Operator directly contacts lining slurry, and there are biggish occupational disease hazards.Using current mechanical means, there are lining process loss It is excessive, while the residue glue in equipment cleans difficulty, uses a large amount of solvent contamination environment.
Summary of the invention
The present invention provides a kind of compact lining spraying equipment, for low, the local thickness that solves current lining coating efficiency The problem of quality problems out of control, process loss is excessive, and residue glue is difficult to clean in equipment.
In order to solve the above technical problems, the technical scheme adopted by the invention is that: a kind of compact lining coating equipment packet It includes: pushing away rubber moulding block, storage rubber moulding block, spray gun pedestal, rotary spray gun, the storage rubber moulding block, which is mounted on, pushes away glue inside modules, the rotation Turning spray gun to be mounted on spray gun pedestal, the spray gun pedestal is connect with storage rubber moulding block, the rotary spray gun high speed rotation, by means of Centrifugal force, lining are dished out by the spray orifice in rotary spray gun pipette tips, and directive motor body inner surface realizes the coating of lining.
Further, described 4 rubber moulding block, storage rubber moulding block, spray gun pedestal, rotary spray gun components of pushing away are independent of one another, by spiral shell Line and Bolted Flanged Connection.
Preferably, it is described push away rubber moulding block by cantilever spray boom, chassis and be mounted on chassis by motor, speed reducer and linear The driving mechanism of mould group composition is constituted;The storage rubber moulding block by storage rubber sleeve, rubber-storing cylinder flange block, detachable take-up housing, bulb, Piston and rubber-storing cylinder upper and lower part fixed block are constituted, and storage rubber moulding block is mounted on inside cantilever spray boom, detachable take-up housing and linear mould Group connection, storage rubber sleeve is filled in piston one end;The spray gun pedestal is by spray gun substrate, center sebific duct, compressed air hose, push-in Pipe fitting is constituted, and center sebific duct one end is connected with rubber-storing cylinder flange block and Quick-insertion type pipe joint, and compressed air hose passes through push-in Pipe fitting accesses substrate, and substrate is connected with cantilever spray boom;The rotary spray gun is mounted on spray gun substrate.
The servo motor revolving speed of rubber moulding block is pushed away, by adjusting to realize the control of slurry flow.
By adjusting the compressed air pressure of input, to realize the control of slurry atomization degree.
In spraying process, pushes away rubber moulding block and piston is pushed to pass through the center sebific duct in spray gun pedestal for the lining in rubber sleeve is stored up It is pressed into rotary spray gun, compressed air is entered by spray gun pedestal internal channel pushes spray gun high speed rotation in rotary spray gun, borrow Help centrifugal force, lining is sprayed by the spray orifice in pipette tips, directive motor body inner surface, realizes the efficient circumferential equal of lining The mesh of even coating.
Equipment provided by the invention, has the advantages that
1. the controllable circumferential direction of coating speed can be reached uniformly by process control piston feed speed, compressed air pressure Spraying.
2. facility compact, each component can quick partitioning disassembly, it is simple that lining slurry flows through design of part, apart from short, slurry Small, easy cleaning is lost.
The precision and efficiency of engine lining production can be improved in equipment provided by the invention, improves the consistent of product quality Property, while being avoided that staff directly contacts slurry, reduce occupational hazards.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of compact lining coating equipment of the present invention.
Specific implementation method
The invention will be further described with example with reference to the accompanying drawing:
As shown in Figure 1, a kind of compact lining coating equipment includes: to push away rubber moulding block, storage rubber moulding block, spray gun pedestal, rotation Spray gun 4, it is described push away rubber moulding block by cantilever spray boom 11, chassis 12 and be mounted on chassis by motor 13, speed reducer 14 and linear The driving mechanism that mould group 15 forms is constituted;The storage rubber moulding block is by storage rubber sleeve 25, rubber-storing cylinder flange block 26, detachable take-up housing 21, bulb 22, piston 23 and rubber-storing cylinder upper and lower part fixed block 24 are constituted, and storage rubber moulding block is mounted on inside cantilever spray boom 11, removable It unloads take-up housing 21 to connect with linear mould group 15, storage rubber sleeve 25 is filled in 23 one end of piston;The spray gun pedestal by spray gun substrate 34, Center sebific duct 32, compressed air hose 33, Quick-insertion type pipe joint 31 are constituted, and 32 one end of center sebific duct and rubber-storing cylinder flange block 26 are inserted fastly Formula pipe fitting is connected, and compressed air hose 33 accesses substrate 34 by Quick-insertion type pipe joint 31, and substrate 34 is connected with cantilever spray boom 11; The rotary spray gun 4 is mounted on spray gun substrate 34.
