Embodiment
[0041] The positioning ring 3 has an inner diameter of Φ62mm, an outer diameter of Φ72mm, and a height of 50mm.
[0042] The outer diameter of guide column 1 cylinder 11 is Φ50mm, the wall thickness is 2mm, and the length is 2950mm. The welding end is provided with a 30° groove for welding with the cone head 12. The cone head 12 has a total length of 283mm, a maximum outer diameter of Φ50mm, a cylindrical end of Φ45mm and a length of 30mm at the lower end, a 2×45° chamfer at the top of the cylindrical end, and a welding end at the other end, which is symmetrical with the cylinder and has a welding angle of 30°. The length is 233mm, and the tip is a spherical surface with a surface roughness SR of 5mm.
[0043] The positioning block 4 is a "concave" block, the outside is 50mm * 45mm, the thickness is 6mm, the width of the notch is 30mm, and the depth is 15mm.

The invention relates to the technical field of liquid rocket engines, and discloses a guide mechanism of a liquid rocket engine cleaning device. The guide mechanism comprises guide columns, guide rails and positioning rings; an engine is fixed on a hoisting support; the guide rails and the guide columns are fixed to a guide support, and the guide rails are parallel to the axes of the guide columns; the positioning rings are fixed to the two sides of the hoisting support; the positioning rings can penetrate into the guide columns and slide up and down along the guide columns, an operator onlyneeds to sleeve the guide columns with the positioning rings while dropping the hoisting support, the positioning rings and the guide columns automatically complete guiding along with dropping of thehoisting support, and the device mainly comprises the four of the positioning rings, positioning blocks, the guide rails and the guide columns, guiding of the positioning blocks and the guide rails isautomatically completed in the falling process as long as the position of the positioning blocks is designed in advance, operation is easy, and time is saved.
Description
technical field [0001] The invention relates to the field of rocket engine manufacturing, in particular to a guide mechanism for an engine cleaning device. Background technique [0002] With the rapid development of my country's aerospace industry, the country has put forward higher requirements for the progress and quality of liquid rocket engine development. After the test run of the liquid rocket engine is successful, the residue after the test run in the engine needs to be cleaned and delivered to the overall unit for launch. At the same time, the engine has high requirements for excess and cleanliness. Therefore, the cleaning work after the test run of the liquid rocket engine is crucial to the final quality of the engine. important. In order to ensure the smooth progress of the cleaning process, the center of the engine needs to maintain a certain coaxiality with the center of the cleaning device. However, due to the large volume of the engine, the high coaxiality re...
