[0074] The present invention provides a processing device for countersinking an elliptical socket on an aircraft. The equipment uses X, Y, Z, A, B, and C axis movements to complete the actual normal alignment of the already made hole on the bulkhead, and then adjusts the swing head posture of the elliptical socket in the bulkhead direction. At this time, the swing direction of the end tool 112 is consistent with the direction of the bulkhead. When making the elliptical socket, the feed shaft and the swing shaft at the end are used to complete the processing of the elliptical socket, which can be specifically divided into two steps: countersinking and swinging. The tool 112 first countersinks the short-diameter socket surface axially by the feed shaft, and then swings to the upper and lower sides of the swing shaft to process the long-diameter socket surface.

[0075] Similarly, after the equipment uses the X, Y, Z, A, B, and C axis movements to complete the actual normal alignment of the holes made on the long stringer, the swing head posture of the elliptical socket in the direction of the long stringer is adjusted. At this time, the swing direction of the end tool 112 is consistent with the direction of the long stringer. Similarly, when making the elliptical socket, the feed axis and the swing axis at the end are used to complete the processing of the elliptical socket, which can be specifically divided into two steps: countersinking and swinging. The tool 112 first countersinks the short-diameter socket surface along the axial direction by the feed axis, and then swings to the left and right sides by the swing axis to process the long-diameter socket surface.

[0076] In summary, the precision machining of the elliptical nest is achieved by using a six-axis machine tool consisting of three linear axes X / Y / Z and three rotary axes A / B / C.
