Embodiment Construction

[0023] This embodiment is a coating device for the flame-limiting layer of solid rocket motor grains, including a coating head 1 , an outer extrusion groove 2 , an inner extrusion groove 3 , a handle 4 , an extrusion rod handle 5 and a connecting rod 6 . in,

[0024] The inner extrusion groove is fixedly supported on one end of the surface of the handle 4 through the connecting rod 6, and an angle of 30° is formed between the lower surface of the inner extrusion groove and the surface of the handle. One end of the Y-shaped extruding rod 5 is hinged on one end of the handle by extruding the handle locating pin 9, and can rotate with the extruding handle locating pin as an axis; Hinged on the two side walls of the outer extrusion groove. The two side walls of the outer extrusion groove are respectively clamped on the outer surfaces of the two side walls of the inner extrusion groove, and the gap between the two side walls of the outer extrusion groove and the inner extrusion gr...

Abstract

A coating device for a combustion limiting layer of a solid rocket motor grain, an inner extrusion groove is fixedly supported on one end of a handle surface through a connecting rod, and a 30° angle is formed between the lower surface of the inner extrusion groove and the surface of the handle. angle. One end of the extrusion rod is hinged to one end of the handle through the extrusion handle positioning pin; the ends of the two hinged rods of the extrusion rod are hinged on the two side walls of the outer extrusion groove respectively. The inner surfaces of the two side walls of the outer extrusion groove are in clearance fit with the outer surfaces of the two side walls of the inner extrusion groove; the rotating positioning pins are inserted into the positioning pin holes on both side walls of the inner extrusion groove and both sides of the outer extrusion groove Inside the arc strip hole in the wall. The coating head is fixed to the outer end face of the hinged end of the inner extrusion groove. The present invention extrudes the slurry to the smearing head of the head through the pressure of the two extrusion grooves, and ensures the continuous coating of the combustion-limiting layer, and can complete the coating of the combustion-limiting layer at one time. The inefficient repeated application of the flame-limiting layer coating process is reduced, and the uniform coating is ensured.

Description

technical field [0001] The invention belongs to the technical field of solid rocket motors, and relates to a coating device for a small-sized solid rocket motor grain combustion-limiting layer. Background technique [0002] The air guide groove of a small solid rocket motor grain needs to be coated with a flame-limiting layer on both sides of the air guide groove after shaping, so as to ensure that the initial burning surface of the rocket engine is guaranteed during combustion, and that the heat insulation layer will not interfere with the propulsion during combustion. Agent debonding occurs. Caused the solid rocket motor to fail. Existing technology is to use general hacksaw blade, single-sided blade to carry out manual coating. After countless times of intermittent coating, the flame-limiting layer after intermittent coating is repaired a second time to ensure the uniformity of the flame-limiting layer coating of the grain and the coating quality of the flame-limiting l...
