Abstract
The utility model discloses an embedded drill sleeve for a template in the technical field of machinery. The embedded drill sleeve adopts an outer shape of a cylinder, wherein an upper groove and a lower groove are formed in the outer circumferential surface of the cylinder respectively; angles a formed between the grooves and a plane are 10-60 degrees; a through hole with the diameter D of 1-50mm is formed in the center of the cylinder; 45-degree chamfers are formed between the upper end and the lower end of the through hole and the edge of the plane; the outer circumference of the cylinder of the drill sleeve is embedded into the through hole of a template to be matched, and is connected in interference fit. By adopting the structure, the problem that the template cannot fit a component in the turn-over process is solved, the difficulty in positioning the template and the component is lowered, and the template positioning accuracy is improved; in addition, the drill sleeve is simple in structure, convenient to manufacture and low in cost; the drill sleeve does not have a protruding part after being installed on the template, and both the two surfaces of the template can fit the component, so that the positioning accuracy of the template and the component can be improved and meanwhile the drill sleeve can be prevented from loosing and dropping off.
Description
Technical field
The utility model relates to a kind of drill bushing of field of mechanical technique, the embedded drill bushing that especially a kind of model is used.
Background technology
Along with the development of digital production technology, model role in aircraft manufacturing more and more weakens, present stage model be mainly used in the inspection of part and drilling of pilot hole, in the time drilling pilot hole, by involutory to model and part, then hole by the position, hole on model drill bushing.As shown in Figure 1, traditional model drill bushing has T " character form structure, drill bushing is embedded in can an outstanding drill bushing cap head on model.Some parts on aircraft have symmetrical structure, in the time using two symmetrical components of model processing, model upset need to be used, when use has the template surface of cap head and part when involutory, model just can not be fitted completely with part, cause model and part location difficulty, also reduced the precision of location simultaneously.Tradition drill bushing and model adopt interference fit to be connected, and in the time holing with model, because drill bit and drill bushing can produce active force, very easily cause drill bushing become flexible and come off, and so just need to reprocess model, and then affect the production efficiency of part.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provides a kind of embedded drill bushing, and this embedded drill bushing is arranged on model without outstanding part, all can fit with part in model two sides, improve the positioning precision of model and part, can prevent that drill bushing is loosening simultaneously and come off.
The purpose of this utility model is achieved through the following technical solutions:
A kind of embedded drill bushing, profile is cylinder, is respectively equipped with upper and lower two annular grooves on cylinder outer circumference surface, the upper surface of upper grooves is inclined-plane, and а crossing with cylinder upper surface angle, and the lower surface of lower grooves is inclined-plane, and а crossing with cylinder lower surface angle, а angle is 10
o-60
o, it is the through hole of Φ 1mm-Φ 50mm that there is diameter D at cylindrical center, the seamed edge of through hole upper and lower side and plane has 1 × 45
ochamfering;
The cylinder excircle of described drill bushing embeds in the through hole of model to be coordinated, and adopts interference fit to connect.
The beneficial effects of the utility model: the utility model adopts said structure, solve the problem that model cannot be fitted with part in the time that upset is used, reduce the positioning difficulty of model and part, improve the precision of model location, simultaneously drill bushing structure is simple, easy to process, with low cost, is arranged on model without outstanding part, all can fit with part in model two sides, improve the positioning precision of model and part, can prevent that drill bushing is loosening simultaneously and come off.

Detailed description of the invention
Embodiment 1
As shown in Figure 2, a kind of embedded drill bushing, profile is cylinder, on cylinder outer circumference surface, be respectively equipped with upper and lower two annular grooves, the cross sectional shape of groove is triangle, and the upper surface of upper grooves is inclined-plane, and а crossing with cylinder upper surface angle, the lower surface of lower grooves is inclined-plane, and а crossing with cylinder lower surface angle, and а angle is 45
o, it is the through hole of Φ 2mm that there is diameter D at cylindrical center, the seamed edge of through hole upper and lower side and plane has 1 × 45
ochamfering, the cylinder excircle of drill bushing embeds in the through hole of model to be coordinated, and adopt interference fit to connect, while boring with model, on drill bushing with groove outer end and part fit tightly, prevented the loosening of drill bushing and come off, because the groove part of drill bushing is upper and lower symmetric construction, therefore solved model in the time that upset is used also can with the precise positioning of part.
Embodiment 2
As shown in Figure 3, a kind of embedded drill bushing, profile is cylinder, on cylinder outer circumference surface, be respectively equipped with upper and lower two annular grooves, the cross sectional shape of groove is trapezoidal, and the upper surface of upper grooves is inclined-plane, and а crossing with cylinder upper surface angle, the lower surface of lower grooves is inclined-plane, and а crossing with cylinder lower surface angle, and а angle is 60
o, it is the through hole of Φ 5mm that there is diameter D at cylindrical center, the seamed edge of through hole upper and lower side and plane has 1 × 45
ochamfering, the cylinder excircle of drill bushing embeds in the through hole of model to be coordinated, and adopt interference fit connect.
Embodiment 3
As shown in Figure 3, the central through hole diameter D of drill bushing is Φ 50mm, and other structures are identical with embodiment 2.
Claims (2)
1. an embedded drill bushing, profile is cylinder, it is characterized in that: on cylinder outer circumference surface, be respectively equipped with upper and lower two annular grooves, the upper surface of upper grooves is inclined-plane, and а crossing with cylinder upper surface angle, the lower surface of lower grooves is inclined-plane, and а crossing with cylinder lower surface angle, and а angle is 10
o-60
