At gear 86, a lifting disk 87, the cam disk of the movement of the device according to the invention 75 and a handwheel 88 carries. Of these, the manure-receiving rotary slide of the rotary machine disk 84 and the gear 86 rotatably on the ne along the workpiece 78 'is the stop shaft, while the disks 83, 85 and 75 screw 89 on the stop screw 90 for so long. and the handwheel 88 is non-rotatably connected to the shaft until the buttons 70 are in the set finishing depth. The lifting disk 87 is in a rotationally fixed position on the template when the tool has reached the housing 109 and is in its rotational position as desired, point A of the workpiece. In that adjustable. now takes over the following area of processing

The stop disk 83 has stop surfaces in the pushbutton the movement of the slide 61 until the shape of four stop screws 89 to 89 '", 40 layer 11 is completely removed. After that, the slide 61 and thus the tool are differently removed from the stop disk 83 1 'by protruding and within this within limits as desired by actuating the magnet 22', 23 and the control element. The stop screws 89 work 64 to 66 lifted from the workpiece 78 returns to its rest position, the fixed stop 45 attached to the slide track 62 runs the rack 105 is screwed onto the raised section of the piece 77. The cam disk 84 is on the cam piece 107 and rotates the toothed wheel 86 along with the stop disk 83 by holding it counterclockwise under tension of the screw 91 connected, which is in a bore 92 to torsion spring 108.

The long electromagnet 22 ', 23 (Fig. 2) is used. This Hole 110 in the disc 102 is designed so that the switch is from one of the stop screws 89 to to operate indirectly at the end of the rotary movement of the gear 86 in the 15 89 '"of the stop disk 83, Clockwise (FIG. 4) the pawl 101 from the council, including a special design of the stop members control wheel 85 against the action of the spring 103 is required. These then consist of a BoI that is lifted. This lifting is of no importance, zen 123, which has a protrusion on its underside as long as the pawl 97 is in one of the teeth 98 of the ratchet 124 and a screw pin wheel 85 engages in its end face. If, however, the pawl 97 »0 zen 125 is screwed in, the position of which is secured by the locking member 94 'in its retracted nut 126.

Held in position, the ratchet wheel 85 is no longer "one" with the bolt 123 and the screw bolt locked against turning. As soon as the pawl 101 125 is also the actuating pin 128 working together because of the lifting of the ratchet wheel 85 by counter to the force of a spring 129 in one by one the cam plate 87 no longer locks in any of the teeth 100 on an actuating member 130 which can be rotated as a shaft 131, the shaft 82 can bar by the torsion spring 108 and against stepping outwards by a Unhindered returned to its original position, cross pin 132 secured. The actuation pin 128 carries in which when the carriage 61 is positioned on its protruding from the stop piece 121 on the workpiece 78 of the stop bolt 89 again the end of a protective screw 133.

By doing pulley 84, the locking member 94, 94 'is raised and the coupling member is a double cone-shaped the pawl 97 is released so that it has an incision 138 at the end face in which a conical end of the disc 85 can rest. Since the contact point 35 engages section of a transmission element 139, the pawl 97 continues here from the cam disk 84 directly to the commercially available switch 122 away than the contact point acts on the other side.

the ratchet teeth 98, the locking member 94 'remains when the tool Γ on there. Without work, until the pawl again at the end of the teeth piece 78 moves the screw bolt 125, the projection 98 on the annular disc 99 has accumulated. , 40 124 and the beginning of the bolt 123 over the pin If the number of ratchet teeth 98 is one greater than 128 away, whereby this in the rotatable actuator the number of stop screws 89 and the number member 130 is shifted axially without this to the ratchet teeth 100 pan one greater than this number. Corresponds to e.g. B. the stop bolt 123 (four stop screws 89, five ratchet teeth 98 to the stop bolt 89, so the carriage begins and six Ralschenzähne 100), so there is a 45 course of the button 70 on the template 71 correspond-intermediate position of the shaft 82, in which None of the claims to retract a little as soon as the tool 1 'has reached the impact screws 89 with the stop screw 90 to the point A on the workpiece 78'. Would work together. Since the cam disc 75 is the end of the machining of the layer 111, the precursors of the machining of the layers 111 to 114 is the. jump 124 on pin 128 and swivels this so-auxiliary slide 32 has held in a position in which 50 as the swiveling actuator 130 counter! rather the chamber 39 is connected to the pressure medium source 27 of the force of the spring 136. When the actuator is pivoted, the switch 122 is actuated in the intermediate position of the auxiliary link 130, the slide 32 is released, whereby, as already indicated, a pulse is sent to the Magnet 22 ', 23 leads to lifting, the control slide in its in Fig.2 the tool 1' from the workpiece 78 is. The posed situation returns. In spite of the fact that the carriage of the copier is positioned, it moves automatically ^! Probe member 70 on template 71 is therefore the back. The slide receiving the copier device then moves by a preset amount in the direction of the slide of the lathe through the end to the workpiece 78 in order to switch the layer 81 back into its rotational position, also controlled by a switch, to machine. Only after the removal of the so-called `` Here '' can the stop member 76 go into its 60 ters of the carriage 61, as described above, back to the starting position, in which for the purpose of machining the layer 112, the stop member 76 goes back to the starting position, in which one is employed again for the purpose of machining the layer 112 the new workpiece. During the next work cycle, a stop bolt corresponding to the screw 89 again works together with a stop screw 90, hammer screw 89. There can be an additional function in operative connection with the switch 122, whereby operation can be switched on, when the tool 65 the projection attached to the stop bolt on the workpiece 78 at a distance from the layer 89 the switch acts as soon as the tool edited along its entire length. Has reached point A on workpiece 78 '.

With the help of the handwheel 88, each of the

ten to retract according to the template as soon as the tool 1 'has reached point B or C on the workpiece 78'. Once the tool Γ has arrived at point A or B , the projection rests against pin 128 again and actuates switch 122.

When machining the layer 114, the projection 124 30 can be arranged on the bolt 123 that the carriage 61 return to its rest position

10

begins as soon as the tool has reached point C or U on workpiece 78 '. A corresponding arrangement of the projection 124 results for the finishing of the workpiece 78 ', the tool beginning to lift off the workpiece 78' when it reaches the point E. In the last two cases, the arrangement of the screw bolt Γ25 and the lock nut 126 can be dispensed with, since the button 70 takes over the guidance of the slide 61 here.
