Abstract

The invention relates to a device which is used for Verduebelung of workpieces, especially of wood materials. It is particularly suitable for small businesses, craftsmen and hobbyists. The aim of the invention is to make their application universal with ease of use of the dowel hole drilling jig and to allow accurate drill rows in use. The object of the invention is achieved in that the drilling jig is not applied centrally, but in each case to a reference edge. Thus, buendige corner joints are always achieved with different materials. Serve on the basic body on one side and at both ends symmetrically arranged stop fields with grid holes, for receiving stop bolts. To fix the gauge in a certain position fasteners are used in unused drill jacks. These fasteners are in two parts and have lever arms, wherein the two corresponding surfaces are abgeschichtete. Through the fasteners lead steel pins which are smashed into the workpiece (wood). By turning a fastener part of the steel pin is dug and loosened. Drill bushes and steel pins are magnetised so that the metal parts stick together.

Inventory description

Title of the invention

Dowel-jig

Field of application of the invention

The invention relates to a device which is used for the arrangement and introduction of holes for doweling workpieces, in particular wood-based materials

Characteristic of the known technical solutions

For the production of corner joints, as well as the joining in the same level lying parts, is used as a connecting element, the dowel connection as the most appropriate 3? orm in furniture and interior design..Dabei find in high-quality dowel boring machines

Use· -

These machines allow rows of bores in any arrangement as well as in the so-called pitch, which is usually 32 mm. ¹ . , , ,

 However, the use of such machines-is only suitable for mass production, since acquisition costs so as setting and changeover times are relatively high. Pur craftsmanship or small series production are mostly used scrubbing aids,

which due to their simplicity, lack the required accuracy. Since drilling is carried out without special guidance, the accuracy of the tapping is still important .. nor is the running of the drill due to different material structure · _;

The use of drill guide strips made of wood under * * · lie, in addition to the accuracy, high wear.

Are known. Drilling jigs with drill bushes made of wear-resistant material allow the .Lochreihen for fitting holes and usually have a single purpose determination ·

In order to achieve an exact arrangement of the dowel holes in craft production or small series production, a dowel hole drilling template has been proposed whose. Basic body, consists of a bar in the drill guides are screwed as needed. Pur the attachment of holes in the frontal narrow surfaces of plates are on both sides angular stop strips provided by means of which, by obliquely arranged slots, even at different plate thicknesses, the Bahrlochreihen are always located exactly centered * Bs .hat. However, it was shown, that at 4-5 Dickentoleranzeu the. Plates different distances of the row of boreholes to the respective reference surface arise and thus different distances or - supernatants may occur at the corner joints »

Also in other proposed solutions, the main focus is on the exact centering on the .. Plattendickenmitte- directed, - so that all proposed solutions have the deficiency mentioned above.

To attach the drilling jig while drilling by hand drilling machine, - be, various. Spann- * * Fastening proposed, which partly in combination with the centering have the disadvantage that their construction complicated and the operation is complicated.

Object of the invention

The invention is intended to eliminate the aforementioned deficiencies in the use of dowel hole drilling jigs of known type »At the same time, the precision of the drilling jig, .., even with different applications, be granted« ^:

Explanation of the essence of the invention

With the universally usable dowel hole drilling gauge. _ä should be possible all kinds of dowel joints, the zoom-reaching in their accuracy in the performance of the dowel drilling machines ........

In contrast to the known solutions, the centering is abandoned and for each assumed only a reference surface »

Furthermore, the fixation and attachment of Bohr teaching is made possible with simpler means in less time · '

The invention is based on the following essential features.

Hardened drill bushes are embedded at certain intervals in a base body.

^Ou find fields with rest holes, the. make it possible to receive stop bolts, which serve as an abutment against the reference surfaces. The drill holes with centric stop bolts allow for reproducible distances of the drillhole rows in steps « ¹ When using stop bolts with eccentrically arranged fixing pins, any intermediate position can be achieved for special cases

By applying to the geweilige reference edge, always flush corner joints can be achieved, even with different material thicknesses or tolerances.

The peers arranged on each bath of the main body make it possible to apply the drilling jig, both for boring dowel holes in the narrow end face, as well. for .. drilling the holes in the wide surfaces for the production of corner joints.

When making drill holes for the arrangement of partitions or floors, - remove the stop pins from the side panels and apply the gauge to an angular crack · ¹

steel pins, which are guided in fastener elements, are used to fasten the drilling jig to the workpiece ·· These fasteners are inserted into the unused drill bushes and the steel fittings are hammered into the workpiece »

The fasteners have a split with beveled! Laugh, which trigger a stroke during rotation of a rope and thus ,, without additional tools, allow the loosening of the steel pins.

The resulting pin holes are insignificant, since they are later hidden

The arrangement of all stop fields on the main body is symmetrical. This makes it possible to apply to right and left sides as well as to right and left narrow end surfaces without changing the drilling jig.

Another feature of the invention is that the hardened steel pins and bushings are magnetised to effect stitching together of the individual parts

By removing the stopper bolts at the ends of the drilling jig any lengthening of the drill string can be effected by displacing the drilling jig. For this purpose, the drilling jig is fastened with at least two fixed or corresponding dowels and thus the accuracy of the row of boreholes is ensured .
