| titleOfInvention | Method for machining butt joint hole of liquid rocket engine frame |
| abstract | The invention discloses a method for processing a butt joint hole of a liquid rocket engine rack, which specifically comprises the following steps: s1, mounting a lower jig; s2, machining a frame body blank; s3, mounting an engine frame blank; s4, mounting an upper jig; s5, cutting and drilling; s6, after the cutting in the step S5 is finished, the locking bolts at the four corners of the upper jig are unscrewed, and the invention relates to the technical field of aerospace equipment processing. The processing method of the butt joint hole of the liquid rocket engine frame can achieve the purpose of drilling production at once by directly using a production jig only through installation fit, well achieves the purpose of drilling production fast and efficiently, can ensure accurate positioning and alignment of drilling without complex positioning procedures, is well suitable for mass production, reduces the workload of production personnel, improves the production efficiency, and greatly facilitates the production of the liquid rocket engine frame. |
