Description

AT . The invention relates to a carriage equipped with a copier to a machine for turning wheel bands; a cross-slide screw, or by means of a friction transmission, which informs the same screw by means of worm gears.

In FIG. 1 shows a view of the support on the front side of the longitudinal slide; FIG. 2 is the same from the end side of the cross slide; FIG. 3 side view of the copier; FIG. 4-movement pattern of the pointer of the copier and cutter; FIG. 5-modified caliper with friction transmission, from the front side of the longitudinal slide; Fig 6 is a view of the same caliper from the front side of the cross-piece slide; FIG. 7 is a top view of the friction transmission.

To the fixed base. In (Fig. 1, 2). The caliper is fastened to the pillar 1, carrying a metal plate 8, on which a metal plate C1 is reinforced through an insulating gasket, having a cutout in the shape of the outer contour of the turned band (Fig. 3, 4). The crossbar 5 is attached to the cross slide 6,

into the hole of which the rod 7 is passed, fixed by the bolt 8 and terminating with the pointer 4, forming together with the above-mentioned plate 5 a machine copier. The end of the cutter .9 extends beyond the front face of the sled, always by the same length, up to the stop with the control bracket 10.

By installing the rod 7, and consequently, the copier pointer 4 to a certain diameter of the bandage, the machine is launched, all the time, the pointer 4 will touch the plate 5, the electric circuit 11-12 will close the electromagnet 14-14, rigidly connected by means of a coupling 16 with a driving shaft. 15, on which gear 17 is mounted, which engages with the gear 18, which sits on the motor shaft of the machine or on the shaft of the pulley. The electromagnet 14 with a closed circuit 11-12 communicates the rotational movement of the disc-wheel 19. freely put on the roller 15 and informing the movement of the cross slide 5 through a pair of conical gear wheels 20-21, worm gear 22-28, mounted on bearings 88 29 roller 50 screw 24, rotating, worm gear 25 and, finally, screw 26. As soon as the cutter deepens by an amount corresponding to the curvature of the profile plate 5, pointer 4 of the copier will move away from it; the chain 11-12 is opened and the screw 26 is rotated, and therefore the cutter feed is stopped. Then the movement of the longitudinal slide again causes pointer 4 to touch plate 5, the electrical circuit closes and the workflow starts again. FIG. 4 is schematically shown by the arrows of the direction of movement of the copier indicator 4 and the cutter 9 during operation of the machine. In order to absorb sparks at the moment of opening the circuit 11-12, the last capacitor 87 is switched on. Instead of electromagnet 14-14, gear 17 and disk 19, shaft 16 can also be connected directly to an electric motor.

In the modified form of the caliper (Fig. 5, 6, 7), instead of electromagnetic (Fig. 1, 2), the friction transmission is applied by disks 31-33, and the disk 32 is also provided with teeth, with which it interlocks, as in in the case described above, with gear 18. The disk 31 is fixed on an intermediate roller 82, equipped with a roller 34 (Fit. 7), which is pressed against the working surface of the copier 55, rigidly connected with a longitudinal slide, with a spring 55. The roller 22 is placed in bearings, fortified on a fixed base B of the machine. Depending on the shape of the copier 55, the distance of the disk 31 from the center of the other disk 32 will vary, and the rotation speed of the screw 26 will change accordingly. By the copier 55, the disk 31 is translated

on the other side of the center of the disk 32, wherein the direction of rotation of the screw 26 is reversed. Instead of the post 1 and the rod 7 shown in FIG. 1, 2, there are applied a pointer 36, placed on a longitudinal slide, and a scale of 57-on a cross slide.

Subject patent.

1.Support to the machine for turning wheel tires, equipped with a copier, characterized by the use of the forward-dispatching-transmission of the transverse transverse sling, w; when the electric circuit 11-12 of the copier 3-4 is closed, the disk-wheel 19, which is freely mounted on the roller, communicates rotational movement and is connected by means of a conical 20-21 gear and a worm gear 22-23 and 24-25 gears with the screw 26 of the cross slide 5.

2. Modification of the caliper described in paragraph 1, characterized in that the friction gear, the disks 55-5 (fig. 5-7) of which are fixed: first, on the drive roller 15, and the second is at intermediate-22, equipped with a roller 34, pressed by means of a spring 55 against a copier 55.
