Device for checking the bracket when working with hand drills and thread cutting units Etc.

The invention relates to a device for checking the bracket when working with hand drills, Hand thread cutting units and the like, wherein it is achieved that the hand tool over the duration of the work in any Angle is kept exactly.

Working with hand drills and the like is an essential activity, especially in the assembly area of mechanical engineering or in the hobby area or the like.

Here it is often necessary that ζ. Β. Threaded holes be attached at a certain angle. The operator is still able to do that To be able to estimate the angle lying in the viewing direction when working, however, is at the latest at the Checking a haltwwinkel outside of his line of sight for the support of an assistant instructed, which is necessary in particular in the case of holes to be drilled horizontally.

The invention has for its object to attach a device to hand drills, which it the The operator enables all mounting brackets himself

and to check with greater accuracy., in particular which are not in. His line of sight when working.

This object is achieved according to the invention by that a device that functions on the basis of gravity, ie a viaduct, pendulum or the like in connection with a scale directly on the hand drill, Hand thread cutting units or the like. is attached.

Further details of the invention are shown in the drawings and are described in more detail below. Show it

Position (1) in Fig. 1 shows a device according to the invention. It represents a viaduct, whose principle is well known. With the help of this spirit level it is possible to do smaller ones to check horizontal angular deviations.

In order to be able to adhere to any deliberately larger Winhel deviations from the horizontal axis when drilling a spirit level with a scale according to FIG. 2 is provided. It is necessary that the inner dial (2)

is attached to the drill and the ring (3) can be rotated around this dial using the spirit level. With the help of this device it is then, for example, a hole under 30 ° is possible To apply angular deviation from the horizontal.

The pendulum according to FIG. 5 also offers this possibility of greater angular deviation

It goes without saying that the devices described work in the direction shown must be attached to the drill in order to check the angular deviations Exercise horizontal axis.

In order to now be able to check all the mounting brackets required for drilling, the ones already described are shown Devices also a device according to FIG. Provided that both above the drill and below can be arranged.

The following function results for this device: The one rotatably mounted in point (5) of FIG Dial (4) is placed with its cams (4a) on the workpiece to be drilled. The pointer (7) on the slow-moving rod (6) then shows the bracket around the vertical on the scale disc Axis (5). In order to adapt to the required drilling depth, the rod (6) can be moved lengthways stored in the sleeve (8) of the drill.

It is easy to understand that with an appropriate arrangement of the devices described also a exact control during vertical drilling is possible.
