Abstract

The utility model belongs to field of mechanical technique, a kind of novel embedded drill bushing is provided, embedded drill bushing is cylindrical symmetry, the face of cylinder Shang Youyi sections that its embedded drill bushing contacts with model are the groove of triangle, the key groove α of groove lateral face and vertical plane composition is 75 °~90 °, and embedded drill bushing is interference fit with model room.There is a through hole at the center of embedded drill bushing, and there is 03.X.03 chamfered edge through hole both sides;The thickness specification of embedded drill bushing determines according to model thickness.The utility model is simple in construction, using symmetrical structure, no positive and negative, two sides can inlay, it is in light weight, manufacturing cost is cheap, is easy to process, installation operation is convenient and swift, after on model, without ledge, model two sides during use is overturn can closely be bonded part, improve borehole accuracy;The unnecessary collision of drill bushing is avoided simultaneously, prevents drill bushing from loosening, coming off.

Description

A kind of novel embedded drill bushing
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
In the manufacturing process of aircraft, model is applied to inspection during manufacture part and drilling.Drill pilot hole, guide hole and in During heart hole, its application method is by model and part pairing, is then drilled according to the upper hole position of model.
Used when drilling two symmetrical components using model, it is necessary to which model is overturn, traditional drill bushing has a protrusion Begun to crop up (as shown in Figure 1) in model 2mm drill bushing, model can be caused to be bonded completely with finished surface after upset.Cause sample Plate and part location difficulty, while borehole accuracy is influenceed, reduce the qualification rate of part.Because drill bushing protrudes model 2mm, in model Using, preserve, during transfer, have unnecessary collision, make using interference fit be set in drill bushing on model loosen, it is de- Fall, so as to reprocess model, reduce the production efficiency of part.
Utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of novel embedded drill bushing, drill bushing structure letter It is single, it is easy to operate, by being improved to drill bushing structure, can effectively solve model during use is overturn and part The problem of can not being bonded, improve positioning precision.Drill bushing is avoided to begin to crop up in model use, preserve, the collision in transfer process simultaneously, Reduce model repair rate.
In order to achieve the above object, the technical solution of the utility model is:
A kind of novel embedded drill bushing, described embedded drill bushing are cylindrical symmetry, its embedded drill bushing and sample There is a groove 3-1 on the face of cylinder of plate contact, the section of groove is triangle, groove lateral face and the wedge of vertical plane composition Shape angle α is 75 °~90 °, and embedded drill bushing is interference fit with model room.
There is a through hole at the center of described embedded drill bushing, and through-hole diameter D isThrough hole both sides have 03.X.03 chamfered edge;The thickness specification of described embedded drill bushing determines that embedded drill bushing thickness H is 1mm according to model thickness Or two kinds of specifications of 1.5mm.
The utility model has following beneficial effect:The utility model provides a kind of novel embedded drill bushing, and its is simple in construction, Using symmetrical structure, no positive and negative, two sides can inlay, in light weight, and manufacturing cost is cheap, be easy to process, and installation operation is convenient Fast, after on model, no ledge, model can closely be bonded part in two sides during use is overturn, Improve borehole accuracy.The unnecessary collision of drill bushing is avoided simultaneously, prevents drill bushing from loosening, coming off.
Brief description of the drawings
Fig. 1 is the front view of traditional model drill bushing;
Fig. 2 is a kind of front view of novel embedded drill bushing of the utility model;
Fig. 3 is the reinforcing process of drill bushing;
In figure:1 drill bushing reinforcing device;2 models;3 embedded drill bushings;3-1 grooves.
Embodiment
As shown in Fig. 2 the utility model is a kind of novel embedded drill bushing, described drill bushing is cylindrical, its face of cylinder On have a groove 3-1, groove 3-1 section is triangle, and the key groove that groove 3-1 laterals face forms with vertical plane is 75°。
In installation process, by embedded drill bushing 3 as the hole of drill bushing to be installed on model 2 at, then struck using wooden mallet Embedded drill bushing 3 is hit, embedded drill bushing 3 is embedded in model 2, finally as shown in figure 3, drill bushing reinforcing device 1 is aligned embedded Drill bushing 3, drill bushing reinforcing device 1 is tapped using hammer, model 2 is inwardly extruded with this, model 2 is squeezed into the recessed of embedded drill bushing 3 In groove 3-1, the frictional force of embedded drill bushing 3-1 external diameters and model 2 is reinforced, completes inlaying for embedded drill bushing 2.

Claims (1)
