The invention relates to the field of airplane repair, in particular to an adjustable drill jig device for copying hole sites of old parts and a using method.
Background
In aircraft repairs, new parts need to be replaced after the old parts of the aircraft have cracked or reached the design life. Due to the technical limit of airplane manufacturing, the internal structure of the airplane is complex and has more curved surfaces, so the newly processed parts are generally not processed with the connecting hole sites in advance. During assembly, after positioning by a fixture and clamping by a pressing plate, holes for connecting a new manufactured part and an airplane main body (such as a main beam and the like) are processed in a matched mode. Generally, after drilling and reaming step by using an air drill, reaming and processing the hole by using a reamer to a size specified by the process, and fastening a newly manufactured part with an airplane main body by using a connecting bolt or a rivet.
The old parts with cracks are disassembled, the old holes can be reserved on the main structure of the airplane, and the hole positions are formed by coordinating and processing the two parts together, so that the actual positions and the sizes of the holes cannot be accurately expressed on a drawing, or the deviation exists between the actual positions and the sizes of the holes and the drawing. Due to the factors that the operation space on the airplane is limited, the skill level of operators is different, the hole axis is not necessarily completely vertical to the end face, and the like, the deviation of 1-3 degrees sometimes exists, and the difficulty in manufacturing the hole position of a new part matched with the hole axis is increased. And, with the higher precision of the connecting holes, the more the hole sites are (up to tens of), the more complex the component structure is, the higher the coordination requirement of the hole sites of the new component is, the greater the manufacturing difficulty is, or it is difficult to ensure that the hole sites on the new component are aligned with the old hole sites on the aircraft body one by one.
The new parts are not provided with holes during processing, and when the new parts are assembled, the new parts are arranged at the matching positions and can shield the old holes on the airplane body, so that the old hole positions cannot be found during construction.
