Embodiment 1

[0027] Embodiment 1, see attached figure 1 , using high-pressure water jets to clean the centering device when the solid rocket motor is charged, it includes: an infrared positioning lamp 20 composed of an infrared positioning bracket 21 and an infrared emitting device 22, a front blocking cover 4, a rear blocking cover 5, and a position adjustment device 8 and a target plate made up of a positioning target plate 6 and a calibration target plate 7; a high-pressure water jet cleaning gun 10 for cleaning an engine includes a gun shaft 11 and a gun head 12.

[0028] The front block cover 4 has the same structure as the rear block cover 5, and the center is provided with an aperture; They are respectively installed at the front port and the rear port of the engine casing 3; the axis of the small hole at the center coincides with the axis of the engine casing 3, and is used to mark the centerline of the engine.

[0029] The infrared emitting device 22 is installed on the high-pres...

Embodiment 2

[0033] Embodiment 2, the centering method when adopting high-pressure water jet to clean solid rocket motor charge, comprises the following steps:

[0034] Step A. Mark the position of the center of the head of the high-pressure water jet cleaning gun 10: run the high-pressure water jet cleaning gun 10 to the farthest end of its stroke, and make the center of the head of the high-pressure water jet cleaning gun 12 contact the positioning target plate 6, and then reverse Move the high-pressure water jet cleaning gun 10 to the initial position, and set a through hole for allowing infrared rays to pass through at the position where the positioning target plate is in contact with the center of the gun head.

[0035] Step B. Install the infrared positioning lamp 20 made up of the infrared positioning bracket 21 and the infrared emitting device 22 on the gun shaft 11 of the high-pressure water jet cleaning gun 10, open the infrared emitting device 22, and adjust the infrared position...

Abstract

The invention discloses an aligning device and method for cleaning of a solid rocket engine through a high-pressure water jetting cleaning gun, belongs to the technical field of engine charge, and particularly relates to the device and method capable of enabling the central line of a high-pressure water jetting gun barrel to coincide with the central line of the engine. The aligning device for cleaning of the solid rocket engine through the high-pressure water jetting cleaning gun comprises the high-pressure water jetting cleaning gun, an infrared positioning lamp, a front blocking cover, a rear blocking cover, a position regulating device and a target plate. An engine case is placed on the position regulating device, the infrared positioning lamp is mounted at the center position of the head of the high-pressure water jetting cleaning gun, and the engine case is located between the high-pressure water jetting cleaning gun and the target plate. By adjusting the position regulating device, infrared rays emitted by an infrared emitting device sequentially penetrate through the front blocking cover and the rear blocking cover and are irradiated to the marked position of the target plate, so that aligning is completed. By means of the aligning device and method, the problems that the central line of the gun barrel deviates from the central line of the engine, and consequently safety or quality is affected by friction between the gun head and an explosive column in the engine and the inner wall of the engine are solved.

Description

technical field [0001] The invention belongs to the technical field of engine charging, and in particular relates to a device and a method capable of making the centerline of a high-pressure water jet gun rod coincide with the centerline of an engine, and avoiding friction between the gun head and an engine internal charge column or casing. Background technique [0002] High-pressure water jet cleaning of solid rocket motor charges is achieved by spraying high-pressure water jets on the surface of solid propellants, cladding layers, and thermal insulation layers to achieve cutting and cleaning of solid propellants, cladding layers, and thermal insulation layers. Traditional manual cleaning is safe and reliable, greatly reducing the danger, and this high-pressure water jet cleaning method is more efficient than traditional manual cleaning methods. Therefore, many domestic units have adopted high-pressure water jet cleaning technology to clean unqualified solid rocket motor ch...
