Abstract
The utility model discloses a drill hole die capable of centering the cut line. The drill hole die comprises a drill plate, a drill sleeve, and a transparent centering element with transparency. Before drilling a sample plate, the cross center line of the transparent centering element is superposed with the cross center line of a hole printed by the sample plate to center the hole, thereby improving the hole position accuracy and eliminating verticality error of the hole by using the drill sleeve to drill holes.
Description
Technical field
The utility model relates to a kind of groove pilot drill casement.
Background technology
Usually, on flat board or curved thin plate class part, bore in a large amount of riveted holes of system, the employing model is made, promptly on the thick steel or aluminum model of 1mm～3mm, press the assembly structure loft of part and draw centerline hole, with the copying of riveted holes center line to model, get drilling by pincers worker ready by the hole cross centre line, be the drill guide workpieces with model again, this position, the hole precision of getting drilling ready is low, and the error of perpendicularity in hole is big.
Summary of the invention:
The technical problems to be solved in the utility model is to provide a kind of boring mould, can realize boring by shining the cross centre line location, hole of printing off on the model.
For solving the problems of the technologies described above, the utility model provides a kind of groove pilot drill casement, comprise: bushing plate, drill bushing, the printing opacity centring element, described bushing plate is an one flat plate, the center has a through hole, described drill bushing is one to have the cylindrical bush of two step cylindricals, drill bushing places the bushing plate through hole, its minor diameter cylindrical cooperates with dull and stereotyped via clearance, described printing opacity centring element, be one to have the cylinder of two step cylindricals, make by transparent material, its minor diameter cylindrical cooperates with dull and stereotyped via clearance, carves cross concave on the cross centre line of cylinder minor diameter cylindrical end face, earlier the printing opacity centring element is placed the bushing plate through hole during use, overlap with copying centerline hole on model by printing opacity centring element center line and to determine the bushing plate position, fixedly behind the bushing plate, take off the printing opacity centring element, change the drill bushing drilling.
The utility model has following good effect than prior art.The transparency that groove pilot drill casement utilizes the printing opacity centring element to have, when mould was located, cross centre line overlapped with the hole cross centre line that the model solarization is printed off and feels relieved, and has improved position, hole precision, uses the drill bushing drilling to eliminate the error of perpendicularity in hole.
Description of drawings
Fig. 1 is that groove pilot drill casement of the present utility model is implemented the centering schematic diagram.
Fig. 2 is the printing opacity centring element of groove pilot drill casement of the present utility model.
Fig. 3 is that groove pilot drill casement of the present utility model is implemented the boring schematic diagram.
The specific embodiment
Below in conjunction with embodiment the utility model is further described.
Groove pilot drill casement of the present utility model has been shown among Fig. 1 and Fig. 2 has implemented the mode of centering, bushing plate 3 is flat boards that a center has a through hole, printing opacity centring element 2 is one to have the cylinder of two step cylindricals, make by transparent material, as organic glass, its minor diameter cylindrical cooperates with dull and stereotyped via clearance, 6～7 grades of quality of fits (H7/h6); On the cross centre line of printing opacity centring element 2 cylinder minor diameter cylindrical end faces, carve cross concave 1, its width and the degree of depth all are 0.1mm, for eye-catching, sign such as cross concave 1 colored red or black color, because printing opacity centring element 2 adopts the transparent organic glass manufacturing, it has the effect of leaded light, and cross centre line 1 is high-visible.Earlier printing opacity centring element 2 is placed bushing plate 3 through holes during centering, overlap definite bushing plate position with copying centerline hole on model 4 by the cross centre line 1 of printing opacity centring element 2.Model 4 thickness are generally steel or the aluminum thin plate of 1mm～3mm, and length does not wait at 200mm～5000mm.
Fig. 3 shows the mode that groove pilot drill casement is implemented boring, drill bushing 5 is one to have the cylindrical bush of two step cylindricals, drill bushing 5 places dull and stereotyped through hole, its minor diameter cylindrical cooperates with dull and stereotyped via clearance, and 6～7 grades of quality of fits (H7/h6) are after the centering, with cramp frame clamp bushing plate 3 and model 4 fixing after, take off printing opacity centring element 2, change drill bushing 5, just can bore drilling.
Claims (2)
1. groove pilot drill casement, comprise: bushing plate (3), drill bushing (5), printing opacity centring element (2), described bushing plate (3) is an one flat plate, the center has a through hole, described drill bushing (5) is one to have the cylindrical bush of two step cylindricals, drill bushing (5) places bushing plate (3) through hole, its minor diameter cylindrical cooperates with bushing plate (3) via clearance, it is characterized in that: described printing opacity centring element (2), be one to have the cylinder of two step cylindricals, made by transparent material, its minor diameter cylindrical cooperates with bushing plate (3) via clearance, carves cross concave (1) on the cross centre line of cylinder minor diameter cylindrical end face.
