Description

The invention constitutes a multi-spindle tenoning machine for making spikes and dovetail-shaped lugs on boards. A distinctive feature of the machine is that its milling spindles are usually a Hioro device placed in a common bar, which receives from the drive a swinging movement, telling it to move along a trajectory in the figure-eight.

In the drawing fit. 1 shows the proposed machine in the side view; FIG. 2 - in v) from above; FIG. 3 shows a section along AB of FIG. one; FIG. 4 shows a section along VG of FIG. one; FIG. 5 shows a section according to the DE of FIG. one; FIG. 6a-d - diagram of the stages of the machine; fit 7a-d is a diagram of the types of work performed by the machine.

The numeral 1 denotes a frame into which the scenes 2 and 3 are inserted, having a groove in which the bar 4 moves with pins) 5 and 1 6. Spindle bearings 7 are inserted into the groove of the bar, the fixed state of which is fixed by rulers 8 and screws 9.

Moving the strips 4 up and down is carried out by pulling 10, connected by MiH with fingers 11 to curved discs 12. These disks, by means of toothed segments 23, 24, with rollers, force the cules 2, 3 to take the required “inclined position”, turning them x 21, 22. The lower parts of the wings 2, 3 and the upper parts 23, 24 of the segments are linked by their teeth with each other.

The rotation of the disk 12 is carried out from the shaft 14 (Fig. 3), equipped with end gear.

Milling shpiveln 15, placed in bearings 7 (Fig. 1-3), receive rotation from the gearbox 16 through the telescopic shafts 17 (or using flexible shafts). The drive gears 18 of the gearboxes are connected by bevel gears to the shaft 19, receiving 1m of rotation from the electric motor (not shown in the drawing).

The various stages of the machine operation are shown “and FIG. 6

The crank disk 12, while continuously rotating, causes the bar 4 to move up and down. When crossing the bar at the extreme top point, it pushes the levers 13, thanks to which the scenes 2 and 3 take on an “aclong position. If we trace the positions of the point A of the plaika at consecutive positions (a, b, c, d, e) of the mekhyayi-zma in FIG. it is easy

to establish that the plaika will make the way of the eight with acute angles (Fig. 7a).

The direction of movement of the strip is marked in FIG. 6 arrows. Consequently, the height of the figure will be described by the axis of the spindle located on the bar.

Therefore, a cylindrical mill, rotating around its axis, will also move in the same direction and, having met the material on its way, will make the corresponding cutout (Fig. 76), F. e. Oblique notch.

The secret groove is also cut by a cylindrical cutter, however, the angles will not be sharp, but with rounded edges equal to the cutter radius, which is quite acceptable (Fig. 7e).

In order to get a straight groove, it is necessary to turn off segments 23, 24, to install and fix the vertical guide mechanism (this mechanism is not shown in the drawing), and the top-bar will only move up "downwards using the mechanism 10, 11 , and the cutter, lowering cb, will cut a straight groove (Fig. 7c).

Eyes to the slanting groove (to the end-to-end and into the sweat) are also cut at the vertical position of the wings, however, not with cylindrical cutters, but shaped (Fig. 7d).

In order to adjust the stroke length of the strip 4 (which is especially important when cutting into the sweat), the curvature disks 12 and the fingers 11 are provided with a series of holes. The insertion of bolts into the corresponding holes, 20 (Fig. 1), connecting the discs 12 with the fingers 11, changes the relative position of these parts, i.e., changes the stroke length of the strip 4.

Work on the machine is carried out as follows. According to the specified spike size, the spindles are mounted at the required distances, which are fixed in this position.

Cutters are installed and the engine is turned on. At the moment when the plank is located at the lowest point, the worker places the d-axis on the table to the stops and presses it with his hands. When lowering and raising the bar grooves are cut through. When the cutters are released from the board, the worker removes the board with all the grooves cut simultaneously and places the next one.

The subject matter of the invention.
