Description

A kind of embedded drill bushing of leading type
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of drill bushing, more particularly to a kind of improvement of model drill bushing.
Background technology
With the development of digital production technology, in the manufacturing process of aircraft, the effect of model increasingly weakens, existing rank Section is mainly used in drilling the guide hole or centre bore of assembling pilot hole used and part itself.When drilling above-mentioned hole, first by sample Plate and part pairing, are then drilled by the hole position on model drill bushing.
But at many of aircraft manufacturing process curved surface part (such as Fig. 1 (a), Fig. 1 (b)), its hole position is according to curved surface The line of vector that direction vector provides, because model has certain rigidity, model such as is provided in its curved surface, model can be along curved surface side To slip or roll, location difficulty, therefore hole position can only be provided in plane corresponding to curved surface.But the line of vector is with making even face not Vertically, because the direction in traditional drill bushing hole with model plane is vertical, so the deviation of boring direction can be caused.Once make Drilled with such model, part can be caused can not to assemble or cause rigging error, so as to influence product quality, reduce the life of aircraft Produce efficiency.
Utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of embedded drill bushing of leading type, by boring Nested structure is improved, and can effectively solve the drilling problems of curved surface part, is reduced the positioning difficulty of model and part, is greatly carried High borehole accuracy.
In order to achieve the above object, the technical solution of the utility model is:
A kind of embedded drill bushing of leading type, including the set of cylinder-shaped body, 2mm thickness emit 4-1, groove 4-2, drill bushing boss 4- 3。
There are a groove 4-2, groove 4-2 section on the face of cylinder that the embedded drill bushing of described leading type contacts with model For triangle, the key groove β of groove lateral face and vertical plane composition is 75 °, and the embedded drill bushing of leading type was with model room It is full of cooperation.
There is a through hole at the center of the described embedded drill bushing of cylindrical leading type, and through-hole diameter D is Through hole and the angle α of vertical plane institute journey are 0 °~75 °, guide bit bore with through hole direction, make drill bit according to set direction Drill part process hole;There is 03.X.03 chamfered edge through hole both sides.The contact surface of the embedded drill bushing of described leading type and model On, there is a drill bushing boss 4-3 using plane where through hole center line as the plane of symmetry, for keyhole direction.Described brill The thickness H that model is stretched into during set processing is determined that thickness H is two kinds of specifications of 1mm or 1.5mm by model thickness;Whole drill bushing Thickness is 3mm~3.5mm.
The beneficial effects of the utility model are:The utility model is simple in construction, using dissymmetrical structure, is drawn with through hole direction Bit bore is led, drill bit is drilled the fabrication hole of part according to set direction.Simultaneously because there is boss with the contact surface of model Presence, can effective keyhole direction.It can reach by positioning in the plane, drill through and curved surface in use The effect of vertical fabrication hole, and accurate positioning, improve assembly precision.
Brief description of the drawings
Fig. 1 (a) is the front view of traditional model drill bushing;
Fig. 1 (b) is the front view of traditional model drill bushing;
Fig. 2 is a kind of sectional view of novel embedded drill bushing of the utility model;
Fig. 3 is a kind of three-dimensional structure diagram of novel embedded drill bushing of the utility model;
Fig. 4 is the mosaic process figure of the utility model drill bushing;
Fig. 5 is the boring procedure figure being enclosed on using Novel drill on model;
In figure:1 model;2 one sides are the part of curved surface;3 traditional non-angular drill bushings;The embedded drill bushing of 4 leading types;4-1 Set emits;4-2 grooves;4-3 drill bushing boss;The theoretical line of vector of 5 drilling parts;The line of vector in 6 actual process holes.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Fig. 1 (a), Fig. 1 (b) are front view, the front view of traditional model drill bushing, and 1 traditional produces on curved surface in figure Model, 2 are that one side is the part of curved surface, 3 is traditional non-angular drill bushing, 5 is the theoretical line of vector of drilling part, 6 is actual The line of vector of fabrication hole.
A kind of embedded drill bushing of leading type, the drill bushing main body are cylinder, and the set for having a thickness to be 2mm emits 4-1, its There is a groove 4-2 on the face of cylinder contacted with the model 1 that tradition is produced on curved surface, groove 4-2 section is triangle, recessed Groove 4-2 laterals face and the key groove of vertical plane composition are 75 °, are interference fit between the drill bushing and model 2.
Under MBD technical conditions, produce plane with model 1 with the line of vector in hole and intersect, draw its position intersected with model 1 Put, and groove 4-2 (as shown in Figure 4) corresponding with drill bushing boss 4-3 is cut out in line of vector projecting direction, when processing model 1, The embedded drill bushing of leading type is tapped in model 1 using hammer.The embedded drill bushing of leading type is used with model 1 and is interference fitted, Therefore it will not fall off.The thickness of drill bushing is 3mm~3.5mm, and 3mm stroke ensures the drilling essence of drill bit enough in use There is 0 °~75 ° of angle in degree, centre bore and the drilling part face of drilling, ensure that drill bit is completed to drill along fixed-direction.
