Airplane fastening hole processing equipment

Abstract

The invention discloses airplane fastening hole processing equipment. The airplane fastening hole processing equipment has the characteristic of high hole processing precision, and a main upright column and a secondary upright column are designed and are in transmission connection through a chain wheel transmission mechanism, so that cross beams can be lifted synchronously, and the airplane fastening hole processing equipment can guarantee that the main shaft has sufficiently high stability during processing, and the processing precision is improved; the airplane fastening hole processing equipment has the characteristic of high hole processing efficiency, and a plurality of drilling main shafts and reaming main shafts are arranged on the same main shaft box and arranged in a staggered way, so that a plurality of holes can be processed simultaneously, drilling and reaming operation can be realized simultaneously, and laser can be used for detecting whether the hole processing precisionreaches the standard or not at once after the holes are processed.

Description

technical field [0001] The invention belongs to aircraft parts production equipment, in particular to an aircraft fastening hole processing equipment. Background technique [0002] Hole processing methods are complex and diverse. The processing method of fastening holes on aircraft is generally drilling, which is suitable for through holes for mounting screws and some rivet mounting holes. Before drilling, first select the appropriate drill bit according to the type and size of the fastening hole to ensure that the size of the hole is within the allowable range. During the drilling process, the verticality of the hole must be ensured first, and the smoothness of the hole wall must be ensured secondly, otherwise the installation quality of the fastening hole will be affected. For some high-strength connection holes that require tight fit installation, reaming is required during processing, and reaming is required after the initial drilling is completed to ensure the smoothne...

AI Technical Summary

Problems solved by technology

[0004] 1) The spindle box is only equipped with one spindle, so that only one hole can be processed at a time, so that the processing efficiency is low;

[0005] 2) Due to the single column structure, when the beam is driven to move up and down, it is easily affected by external or self-vibration, and the headstock shakes slightly, which affects the machining accuracy;

[0006] 3) The initial drilling and reaming are carried out separately. After the preliminary drilling is completed, it is necessary to stop the machine and replace the drill bit on the spindle with a reamer, and then ream the hole, so that the hole processing efficiency is low;

[0007] 4) After the reaming is completed, it is necessary to stop the machine and use a laser detector to detect the formed hole, so that the processing efficiency of the fastening hole is low
