The purpose of the present invention is to improve the previously known brush drilling and tamping machines, in which the drilling and tamping devices work horizontally and the brush sticks the Tools by means of a swingable or linearly displaceable frame are to be set up in such a way that on the machines also doubly curved, so-called offset brushes can be processed, as is the case with machines with stationary Frame for the work tables and with vertically working and up and up moving tools has already been achieved.

For this purpose the new machine is set up in such a way that the brush sticks Frame frames that swing or move in a straight line in clamping plates and slides also all to the movement of the. Workpiece slide necessary machine parts including the double curved disk (template disk) known per se, see above that in the fixed frame only the main drive shaft and the moving parts for the drilling and tamping device, for moving the frame supporting the brush woods and are arranged for the temporary rotation of the cam disk (template disk).

With this construction, the machine remains in spite of the movement of the brush sticks supporting frame at any time the rigid connection between the workpiece slides and the curve (template) disk.

An example embodiment of the new machine is illustrated in the drawing.

Fig. Ι is a side view,

Fig. 2 is a front view,

Fig. 3 is a top view,

Figures 4 and 5 show details.

On the main frame of the machine, the bristle tamping device of the known type is attached first at A and the drilling device driven in a known manner at -B (Fig. 3). C is the swinging frame that carries the brush sticks in clamping plates.

The main drive shaft arranged in the main frame is in a known manner by means of Pulley or the like. (See Fig. 2) moves. A gear 2 is firmly wedged on it, which is in engagement with the gear 3 of an adjacent shaft. On the Axis of this wheel 2 are two disks 4 and 5, which are provided with curved guides are (see Fig. 1). The frame C is moved by means of rods 32 through these curved guides, which is rotatably mounted on the axis 6 below. The curved discs could of course can also be replaced by other movement elements.

On one side of the swinging frame C is now the well-known curve

Claims (1)

disk (template disk) 7 attached, from which the movement of the workpiece carriage should take place. The cam 7 has corresponding cam guides on both sides. In the one a rail 9 is guided by means of pin 8 (see. Fig. ι and 2), which on the back is designed as a rack and, as a result, engages with it when it is moved stationary wheel 10 rotates, the axis of which is guided upwards and carries a gear 11 above, which is in engagement with the rear side of the carriage 12, which is designed as a rack. Of the Slide 12 makes so when the pin 8 is shifted in one of the curve guides Disk 7 a reciprocating movement in the horizontal direction. The carriage 12 is held in the clamping frame 13 (see especially Fig. 1), and this receives its reciprocating Movement in the vertical direction with the help of the rod 15 attached to it at 14, which are attached to the disc 7 at their end by means of the pin 16 in the outer one Curve guide is running and is performed at 17. The cam disk 7 is driven jerkily with the aid of a pawl 24 (see FIGS. 1 and 4), which is arranged in the main frame and is moved from the main shaft 1 by means of a pair of gears 18 and 19. On the axis of the gear 19 sits a disc 20 with curved guides on the sides. One of the curved guides (see FIG. 4) moves a double lever 22 by means of a rail 21, which lever acts on a linearly guided slide 23 on which the pawl 24 is rotatably mounted. The switching pawl is pressed into the toothing of the disk 7 by a spring 25 and the switching movement takes place through the oscillation of the double lever 22. But as soon as the frame is so far advanced that the drilling and tamping device comes into effect, the brush sticks must stand still, so the disc 7 must not be switched at this time, ie the pawl 7 must counteract the action of the spring 25 are disengaged. This is done by the curved guide 26 (FIG. 5) provided on the other side of the disk 20, from which a second double lever 28 is moved by means of a spring pin 27, which at the end carries a facon piece 29 (see FIG. 1), which is slightly below an extension of the pawl 24 is located. If the lever 28 is now depressed by the rod 27 as a result of the curved guide 26, the facon piece 29 moves upwards and lifts the pawl 24 out of the toothing of the disk 7 against the action of the spring 25. The pawl remains in this position until the drilling and plugging is effected and the frame C is supposed to move back again, then the facon piece 29 sinks down, the pawl comes back into engagement with the toothing of the disc 7, and the lever 22 effects the switching movement again. Each time the machine is engaged for the first time, it is expedient to use a crank 30, whose gearwheel with a gearwheel 3) mounted on the axisj of the cam disk 7 in Engagement is. '·' I In the drawn embodiment, i in which onser "the stuffing device also a Drilling device is arranged, there are on the carriage 12 "haturgemäfs two clamping devices for one brush body each. Of course, the machine can also only be used for drilling or just for tamping will. It is of course also possible to multiply the machine. Patent-A ν Spruch; Automatic brush drilling and tamping machine with horizontally positioned tools and a frame which can be moved against them and which carries the brush sticks, characterized in that the movable rack frame (C) requires all of the slides (1 2; 1 3) holding the brush sticks to move Machine parts, including the template disk (7), so that from the fixed frame of the machine carrying the main drive shaft (1) only the circuit, the template disk and the movement of the frame (C) itself take place. - 1 sheet of drawings.
