Fiachbaadaut milling device »

Flschbaadnuten have been mortised from land or by means of a incorporated by tape-driven apparatus.

The present invention provides the carpenter with a motor driven one Milling machine on hand, with which a modern and clean machine Production of fish tape grooves is achieved. Next is a use.

possible on drilling machines or other fast-starting shafts « The drawing shows an example of an implementation:

Fig. 1 front view of the complete device

Fig, 2 longitudinal section · · "according to MnIe A-B

FIg * 3 cross section · · "along line C-S

The motor a drives at high speed via the sprocket b and chain the shaft d, which carries the crank disk e, on the sprocket e with a corresponding gear ratio, screw f, which serves as a crank pin in the crank disc e can In Oewlndelßchern on different Ea * are used »so that different lifting heights can be set« The knife holder g is moved up and down by means of the crank pin and slides in its upper part (part in a swallow Tail-like shaped guide piece i, which with its pivot i in an elongated hole y, which is mounted in the carriage k, adjusted can be, whereby the length and depth of the fish tape groove in connection is adjusted with the setting of the lift height. The exchangeable knife h is attached to the knife holder using screws ζ attached and 1st at the lower end with corresponding cream teeth * Corresponding knives are available for different hat widths

The carriage k is in guide columns 1, which piece in a cross are attached. «up and down. Support and fastening rails n, are also attached to this crosspiece by means of screws To attach the device to the one to be provided with a fish tape groove Wooden frames r are on the one hand two adjustable and fixable lugs o * with which the position of the fish tape groove on the wooden frame can be adjusted, attached, and two more movable ones Latches p, with tensioning screws q.

The motor is secured by a clamp s or a flange on the slide k attached «

The depth of the butt can be adjusted using an adjusting ring t A handle u attached to the slide k is used to operate The upward and downward movement · For this, a corresponding attached lever serve

ρ 45 756 sheet 2. Flschbandnut-milling device For the automatic lifting of the slide with tool and drive »a compression spring ν is advisable to be attached to one of the guide pillars is rotatably mounted, adjusted »afterwards, the lug x is swiveled out again · The operating mode of the device is now as follows: The ready-to-use device is placed with the support rails m, n, on the milled wooden frame and through the adjustable lugs ρ and clamping screws q The distance Her Hut from the belt of the bolt frame is set beforehand using the lugs ο.Sun, the motor a is switched on and the slide k with ferkzeug g, hf is quickly pushed down using the handle or lever η, whereby the knife h the Hat cuts cleanly · Chips produced by oils are automatically ejected · Bach reaches the deepest position ng, which is set with the adjusting ring ^, the slide bar k is pulled up, which process is supported by the compression spring ν · The device can now be loosened and used The position of the butt of the wood filament in the longitudinal direction can be adjusted · Bas changing the knife for different butt widths or for sharpening «is done by unscrewing the fastening screws ζ, also changing the hat length and depth by changing the lubes by moving the crank pin f in the crank disk, as well as by moving the pivot pin i 'of the guide piece 1 in the elongated hole y. It should be noted that the bottom of the hat is cut almost straight «The milling device is also suitable for attachment ζ · Β · to drilling machines» The drive can be provided by a flexible shaft · In this case the motor with chain drive is no longer required «Patent anaprühe s 1) Fischbandnut milling device characterized in that a knife (h) corresponding to the desired width is set in up and down or back and forth movement by a rapidly rotating crank disk (e) and crank pin (f) »and a knife holder with the knife (h) in a swiveling guide piece (i) and the motor {a) in an up and down slide {k) "which is guided on 2 jjiar, allelic columns or guide rails (1)" » 45 156 Sheet 3.
