Abstract
The invention belongs to the technical field of aviation manufacturing, and relates to a processing method of a radial small hole in an aviation drill jig. The method comprises the following steps that 1, a bushing is arranged on a substrate, and a fastening screw is dismounted; 2, a cutter is selected, and a positioning blind hole is formed in a position of a to-be-processed hole of a drill jig part, wherein the positioning blind hole is coincident with the center axial line of the to-be-processed hole, and the diameter of the blind hole is smaller than the diameter of the to-be-processed hole; 3, drill chips are blown out by an air gun, a drill bushing is arranged on the bushing and is aligned with the positioning blind hole of the drill jig part for drilling the hole, and the coarse processing of the processed hole is completed; 4, the drill bushing is taken out, drill chips are blown out by the air gun, and a reaming sleeve is arranged onto the bushing for realizing the hole reaming on the processed hole formed in the drill jig part. The processing method has the advantage that the precision and the qualification rate of the processed hole can be obviously improved.
Description
Technical field
The invention belongs to aero-manufacturing technology field, relate to the processing method of the radial hole in a kind of aviation drill jig.
Background technology
In the boring of aeronautical product, usually adopt Special drilling jig to process, its operation principle overlaps with hinge the processing realizing radial hole in drill jig by changing drill bushing, and its process is specific as follows: be arranged on by lining on matrix; Drill jig is arranged on lining, and compresses with trip bolt; Hole, realize roughing; Take off lining, and blow out drilling cuttings with air gun; Hinge cover is arranged on lining, and compresses with trip bolt, ream, realize the fine finishining of boring.
In said process, drill jig is the symmetry utilizing the clearance control between drill jig and drill bushing to realize between processed hole and benchmark cylindrical, because processed hole requires to overlap with any bus of location cylindrical, therefore drill bit exists an external force in the moment with drill jig feature contacts, because drill bit poor rigidity causes drill bit easily drill jig part hole drill to be caused the center of actual apertures and the offset distance of theoretical center partially.Existing technology requires very high to the technical merit of processor, and part qualification rate is lower.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of technical merit to processor less demanding, accurately can locate, stablize the processing method of radial hole crudy in processed drill jig.
Technical scheme of the present invention is: the processing method of the radial hole in a kind of aviation drill jig, is characterized by described processing method as follows:
Step one, is arranged on lining on matrix, and is taken off by trip bolt;
Step 2, selects cutter, makes a call to a Blind locating holes in the position in the processed hole of drill jig part, the central axes in Blind locating holes and processed hole, and the diameter of blind hole is less than the diameter in processed hole; The intensity T of described cutter should meet following formula:
T＝M/0.2d
3≤[T]
In above formula, M is moment of torsion,
unit Nmm; P is the power transmitted, unit K w; N is the rotating speed of axle, unit r/min; D is the diameter of axle, and unit is mm; [T] to be material allowable turns round shearing stress, units MPa;
Step 3, blows out drilling cuttings with air gun, drill bushing is installed to Blind locating holes lining being aimed at drill jig part and holes, complete the roughing in processed hole;
Step 4, takes out drill bushing, blows out drilling cuttings with air gun, hinge cover is installed to lining and reams to the processed hole on drill jig part.
Beneficial effect of the present invention: the processing method of radial hole of the present invention can solve directly adopt drill bit add man-hour due to the face of processing be arcwall face, cutting force is large, the thin poor rigidity of diameter of drill bit causes adding anchor point skew in man-hour, and the problem offset occurs for the position in processed hole and positioning datum; Method of operating of the present invention is simple, and verified in practice, the qualification rate of part brings up to 100% by 50%.
Accompanying drawing explanation

Fig. 2 is the structural representation of the cutter selected in the present invention;
Wherein, 1-lining, 2-drill bushing or hinge cover, 3-matrix, 4-drill jig part, 5-cutter, 6-trip bolt
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Refer to Fig. 1, it is each part position relations schematic diagram in the invention process process; Refer to Fig. 2, it is the structural representation of the cutter selected in the present invention; Wherein, 1 is lining, and 2 is drill bushing or hinge cover, and 3 is matrixes, and 4 is drill jig parts, and 5 is cutters, and 6 is trip bolts.
Concrete procedure of processing is as follows: step one, is arranged on matrix by lining, and is taken off by trip bolt;
Step 2, selects cutter, makes a call to a Blind locating holes in the position in the processed hole of drill jig part, the central axes in Blind locating holes and processed hole, and the diameter of blind hole is less than the diameter in processed hole; The intensity T of described cutter should meet following formula:
T＝M/0.2d
3≤[T]
In above formula, M is moment of torsion,
unit Nmm; P is the power transmitted, unit K w; N is the rotating speed of axle, unit r/min; D is the diameter of axle, and unit is mm; [T] to be material allowable turns round shearing stress, units MPa;
Step 3, blows out drilling cuttings with air gun, drill bushing is installed to Blind locating holes lining being aimed at drill jig part and holes, complete the roughing in processed hole;
Step 4, takes out drill bushing, blows out drilling cuttings with air gun, hinge cover is installed to lining and reams to the processed hole on drill jig part, complete the fine finishining in processed hole.
Following table be use the present invention process the radial hole of drill jig part process data table (drawing requirement symmetry 0.1, certain batch in totally 92 process every 5 to detect time processing data as follows):
