Abstract
The utility model relates to a verticality guidance drilling jig. A bush is coaxially arranged in an outer shell of a drilling jig, a through hole is formed in the bush, a small circle acting surface and a big circle acting surface are respectively arranged at two ends of an outer shell of the drilling jig, a plane is arranged on the big circle acting surface, and the plane is tangent with a corresponding circle of the small circle acting surface. The drilling jig is small in size, convenient to carry and use, and simple in operation, and greatly improves hole manufacturing precision.
Description
Technical field
The utility model relates to a kind of perpendicularity guiding drill jig, is used for the problem of the perpendicularity of correction drilling process.
Background technology
Continuous development along with science and technology, the required precision of part assembling is also more and more higher, but some specific position in process of production still needs manual drilling, slightly drift angle, structure are opened wide on the position that can't use drilling jig grippers such as tripod, the no guide hole framework accessory inadequately with operation planar drilling, boring can't guarantee perpendicularity, cause the axially bored line deflection, and correct difficult, and then cause the counter boring deflection, there is unidirectional gap to occur after rivet or the bolted, influence type quality, incur loss through delay the payment of product.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of perpendicularity guiding drill jig, and this drill jig not only volume is little, be easy to carry, and also easy to use, simple to operate, improved the drilling precision greatly.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of perpendicularity guiding drill jig, and the coaxial lining that is provided with is provided with through hole in the lining in the drill jig shell; The two ends of drill jig shell are respectively roundlet acting surface and great circle acting surface, and the great circle acting surface is provided with the plane, and the corresponding circle of this plane and roundlet acting surface is tangent.
The length of described lining is less than the length of drill jig shell, and leaves drilling cuttings at the two ends of drill jig shell inner periphery and stockpile groove.
This perpendicularity guiding drill jig adopts said structure, goes for the environment of various borings, and is convenient and swift.
The length of lining is less than the length of drill jig shell, and is positioned at the middle part of drill jig shell inner periphery, is convenient to the accumulating of cutting swarf, chip removal.
Description of drawings
Fig. 1 is the front view of perpendicularity guiding drill jig.
Fig. 2 is the axonometric drawing of perpendicularity guiding drill jig.
Fig. 3 is application examples one application drawing of perpendicularity guiding drill jig.
Fig. 4 is application examples two application drawings of perpendicularity guiding drill jig.
Fig. 5 is application examples three application drawings of perpendicularity guiding drill jig.
The specific embodiment
As depicted in figs. 1 and 2, a kind of perpendicularity guiding drill jig, the coaxial lining 2 that is provided with is provided with through hole in the lining 2 in drill jig shell 1; The two ends of drill jig shell 1 are respectively roundlet acting surface 3 and great circle acting surface 4, and great circle acting surface 4 is provided with transverse plane 5, and the corresponding circle of this transverse plane and roundlet acting surface 3 is tangent.The length of described lining 2 is less than the length of drill jig shell 1, and leaves drilling cuttings at the two ends of drill jig shell 1 inner periphery and stockpile groove 6.
Its use state as shown in Figure 3, part to be holed is the inclined-plane, perpendicularity guiding drill jig overlaps with piece surface with great circle acting surface 4, carries out the processing in hole by the guiding of lining 2; As shown in Figure 4, part to be holed is provided with boss, and bore position and lug boss position are nearer, can drill high accurate hole to save the space with transverse plane 5 near boss; As shown in Figure 5, carry out drilling in the zone that opens wide inadequately, can adopt roundlet acting surface 3 to contact with piece surface, carry out the processing in hole by lining 2 again.So this perpendicularity guiding drill jig is suitable for the various occasions of drilling, drilling is convenient, fast.
