[0069] Working principle of the present invention:

[0070] When it is necessary to manufacture a new type of double-cavity spinning joint, first select the raw materials used for the double-cavity joint, and then use a sawing machine to cut the materials. After cutting the materials on the sawing machine, the blank of the double-cavity joint is rough-turned and fine-turned in turn to process the outer circle, step and joint thread. After rough turning, the outer circle is tempered, and then the marking hole is drilled. Then the double-cavity melt hole and the mounting hole are processed, and the thread head and tail and excess thread are removed. Then the two inclined holes are processed using a rotating dividing plate, and then the explosion-proof hole is processed. After all straight holes and inclined holes are processed, polishing and grinding equipment is used to grind the hole mouths of the straight holes and inclined holes, and then vacuum nitriding heat treatment will be carried out. Finally, pins are knocked into the finished product of the new double-cavity joint, and then it can be inspected and put into storage.
