Abstract

The invention discloses a rotary part drilling method and a drilling clamp. The drilling clamp comprises a drill plate, a drill jig base, a sleeve and a molded surface sliding block. Drill jig holes matched with rotary part normal holes are formed in the funnel wall of the drill plate. A center hole matched with the sleeve is formed in the center of the drill jig base. A polyhedron matched with arotary part is arranged on the lower surface of the drill jig base, and each surface corresponds to one normal hole of the rotary part. The sleeve is provided with passing holes corresponding to the drill jig holes. The pressing edge of the drill plate and the annular edge of the sleeve can be connected to a connecting table at the upper end of the drill jig base in a pressing mode. The rotary part to be machined is placed between the sleeve and the drill plate for fixed clamping, and the molded surface sliding block is compressed onto the bottom of the rotary part through a compression bolt.One surface of the polyhedron at the lower end of the drill jig base is attached to the table board of a machine tool, and holes in the corresponding directions can be machined through the machine tool.

Description

technical field

[0001] The application relates to aircraft manufacturing technology, in particular to a drilling method and drilling jig for rotary parts. Background technique

[0002] There is a special class of rotary parts in the aircraft parts system. These rotary parts are approximately in the shape of a funnel. There are many normal holes on the rotary cone surface of the parts that need to be processed. The relative position accuracy and relative return of these processed holes The position accuracy of the rotating shaft is required to be high. Since these holes are normal holes on the rotary cone surface, the direction of the holes is not perpendicular to the rotary axis of the part, but at a certain angle, so it is difficult to effectively drill these holes on the drilling machine in the traditional way. In traditional machining, multiple processes are generally used to drill these holes separately with multiple drilling jigs, but multiple drilling jigs are bound t...
