Description
Technical field
The utility model relates to the measurement mechanism of the monolateral thickness of a kind of coating, particularly the measurement mechanism of the monolateral thickness of solid rocket motor case external surface coating and method.
Background technology
At present during some Design of Solid Propellant Rocket Engine, at housing outer surface coating composite coating, after curing of coatings, there is certain degree of hardness.Absorbing laser energy when laser irradiates, thus weaken or eliminate the strike of laser to aircraft.Existing process adopts spraying and the shaping coating of knife coating procedure, and thickness is ensured by coating weight, lacks reliable measuring method to the monolateral thickness of coating.
After surface of shell applying coating, reliable measuring method is lacked to the monolateral thickness of coating.Prior art measures with coating back casing diameter before coating, calculates the bilateral molding thickness of coating, cannot grasp the monolateral thickness of coating by coating back casing diameter and coating procapsid diameter.
Summary of the invention
The technical problems to be solved in the utility model is to provide the measurement mechanism of the monolateral thickness of a kind of coating, to solve the problem of the measurement of the monolateral thickness of solid rocket motor case external surface coating.
For solving the technical matters existed, the technical solution adopted in the utility model is: the measurement mechanism of the monolateral thickness of coating, comprise support 1, I-shaped leveling ruler 3 and pit gauge, described support 1 is arranged on the skirt end face of both sides before and after solid propellant rocket, applies the fixing of the same position of the I-shaped leveling ruler 3 of front and back for coating; Described I-shaped leveling ruler 3 is installed on the same position of the coating coating front and back being placed on support 1; Described pit gauge is for measuring the distance between I-shaped leveling ruler 3 and solid rocket motor case surface.
As long as support 1 of the present invention ensures that I-shaped leveling ruler 3 can be installed on the same position of the coating coating front and back being placed on support 1, conventional any method can be adopted or utilize the threaded hole of skirt before and after solid propellant rocket to be fixed.
The measuring method of the monolateral thickness of coating, the steps include:
Before coating coating, before and after solid propellant rocket support 1 being arranged on same level skirt end face threaded hole position on, after installation, I-shaped leveling ruler 3 is lain in a horizontal plane in frock, measure the distance between I-shaped leveling ruler 3 and solid rocket motor case surface with pit gauge;
After coating coating solidification, by same method again by former installation site, support 1 and I-shaped leveling ruler 3 are reinstalled to the position before coating coating, then measure the distance between I-shaped leveling ruler 3 and solid rocket motor case coating surface with pit gauge
The difference of the distance between I-shaped leveling ruler 3 and solid rocket motor case coating surface and the distance between I-shaped leveling ruler 3 and solid rocket motor case surface is the monolateral thickness of the coating of measurement point.
Beneficial effect:
Compared with prior art, present invention achieves the measurement of the monolateral thickness of solid rocket motor case coating, measuring accuracy is high.
Accompanying drawing explanation
Fig. 1 thickness measure frame scheme of installation;
Fig. 2 is the sectional view of Fig. 1;
In figure, comprise support 1, bolt 2, I-shaped leveling ruler 3.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in accompanying drawing 1-2, the measurement mechanism of the monolateral thickness of coating, comprises support 1, bolt 2, I-shaped leveling ruler 3 and pit gauge, and support 1 is arranged on before and after solid propellant rocket in skirt end-face helical hole respectively, and fastening with bolt 2; I-shaped leveling ruler 3 is installed on the same position of the coating coating front and back being placed on support 1.
Before and after the solid propellant rocket that support 1 is installed, skirt end-face helical hole in same level position, should ensure that frock is horizontal.
I-shaped leveling ruler 3 is installed and is placed on after on support 1, by different measuring points position at I-shaped leveling ruler 3 end face mark slotted line, by pit gauge measurement markers slotted line and surface of shell distance.
The measuring method of the monolateral thickness of solid propellant rocket coating of the present invention, comprises the steps:
1) according to the measurement mechanism of the monolateral thickness of coating thickness requirement design coating;
2) mounting bracket 1 and I-shaped leveling ruler 3 carry out the range observation between solid rocket motor case surface and I-shaped leveling ruler 3 reference field;
3) range observation between coating surface and I-shaped leveling ruler 3 reference field is carried out by former installation site mounting bracket 1 and I-shaped leveling ruler 3 after curing of coatings;
4) the monolateral thickness of coating is calculated according to the distance of fore-and-aft survey.
The measurement mechanism of the present embodiment and measuring method can measure the monolateral thickness of coating on circumferencial direction 18 buses, and a bus can distribute according to different measuring positions multiple measuring point, measuring accuracy 0.02mm.
