Utility model

Horizontal auxiliary drilling device for holding a vertical hand drill,

The invention relates to a horizontal auxiliary drilling » Device for holding a vertical drilling machine.

There are already auxiliary drilling devices for the inclusion of Hand drills are known and set up as such to be fixed in the form of a column or also pivotable in a pivot point. However, these and other known types have the disadvantage that the workpiece to be drilled is the same as that to be carried out Drill holes under the drill changed, i.e. » must be laid «This is the case, for example, with an auxiliary device in a fixed columnar shape, or swiveling through a pivot point, required when making several holes in the workpiece, the workpiece before each new hole to be carried out either laterally and or to the rear or to move forward on the drilling table. Especially when drilling a number of holes on a workpiece level the clamping of the workpiece leads to considerable loss of time, is very cumbersome with heavier workpieces and is particularly useful if drilling devices are also used to inaccuracy and easy damage to the oiling devices »

These disadvantages are eliminated by the invention, which is essentially characterized in that the auxiliary drilling

The device consists of a knee joint-shaped bearing, one of which is a free joint end as a fulcrum in one Wall mount or a transportable column stand and the other free joint end bracket-shaped for receiving a stationary and with a longitudinal groove or the like. Provided axis is formed, the latter for receiving a Yertikal hand drill, which can be installed and fixed at any height, is used.

The invention is shown in one embodiment on the drawing in FIGS. Show it?

Pig. 1, the horizontal auxiliary drilling device with a built-in Yertikal hand drill in elevation

Pig. 2, the same in plan from Pig. 1y

Pig. 3> the same in one, in the different possibilities Position setting angled in the horizontal plane for a drilling process

Pig. 1: With 1 the rear articulated arm part is referred to, which e.g. is rotatably mounted in a wall bearing 8 · The wall bearing 8 can also be used instead of a transportable Be trained through the stand. This rear articulated arm— Part 1 is formed in the shape of a fork, for example, to accommodate the front articulated arm part 2, which is in the fork 7 is horizontally pivotable. The articulated arm part 2 is bow-shaped 5 for receiving in its free end a fixed axis 4 is formed. The fixed axis 4 is provided with a longitudinal groove, for example, in The one bearing block 5 for receiving the vertical drill 6, also adjustable in height fixable, is arranged. 9 with a work table, with 10 a workpiece to be drilled with several holes is designated - Pig. 1 and Pig. 3 ·

Fig. 2 shows the auxiliary device in an extended position, the rear G-elenkarm 1 is inevitably swiveled out due to the unrerrandliehen pivot point bearing in the bearing 8 in the direction of arrow E ₁ or Ή.2, depending on whether a backward or forward displacement of the vertical drilling machine for the drilling process in the workpiece is required.

Pig. 5 shows such a mode of operation and displacement of the Tertikai hand drill in the installation of the above novel auxiliary device and clearly shows that when using and the mode of operation according to the invention, the disadvantageous storage of the workpiece 10 since then the work table 9 is no longer required after each drilling process.

It should be added at this point that the choice of the lever arm length of the rear articulated arm 1 (i.e. measured from Pivot bearing 8 up to the fork 7) to the front articulated arm 2 (i.e. measured from the fork 7 to the central axis of the vertical " Hand drill 6) both in a ratio of 1: 1, or as a translation can be selected as desired, without the basic ge » thank to leave the invention. Likewise, the shape of the front articulated arm 2 can also be used instead of in a bow shape 3 with a fixed axis 4 for receiving the bearing block 5 of the vertical hand drill, with one perpendicular to the horizontal Pivoting movement of the knee joint-shaped bearing brought into connection Prismatic guide on which the bearing block 5 with a corresponding Counter-guide adjustable together with the vertical hand drill slide can be brought to execution.
