Description

 Copying machines for making celluloid articles and the like of materials are known, using a bearing carrier roller and cutters balancer, a drum with a groove for communicating a workpiece and a model from the shaft, and a planetary gear to the drum for adjusting speed.

In the proposed copying machine, a mechanism is applied for rotating and feeding the workpiece and the model consisting of a hollow cylindrical rod with a cartridge for receiving and clamping during the working movement of the workpiece.

The designated cartridge is provided with a long keyway groove for a tongue on its tubular axle receiving rotation from the drive. A rod, for feeding the workpiece, is placed in a bearing associated with sleds carrying a finger for the fist groove on the drive drum.

.In FIG. 1 shows a section along the line ABCDEFna of FIG. 2; FIG. 2 shows a section along the / CZ line in FIG. one; FIG. 3 is a side view of the machine.

In the housing / (Fig. 1), the axis 3 rotates the floor, in which the cartridge 4, screwed on a hollow cylindrical rod 5, is fed a long, celluloid workpiece 5, passing in translational-rotary motion MMMO of the cutters 38 and 5P (Fig. 3), fixed in the mandrel 37, driven in rocking movement through the roller 36, the lever 35, the roller 34 from the model // (Fig. 2). The rod 5 is rotated from axis 3 by means of a stepped tongue 8 ,. on which sits the jaws 7 (fig, 1).

In order to grip a new length of material corresponding to the length of the product, the rod 5 with the cartridge is moved to the left, extending from axis 3-Long, which protrudes in the latter case, the end of the rod 5 is supported by a ball bearing 6.

The support part 6 is attached to the basement to the slide 12 (Figures 1 and 2), having movement along a trapezoidal guide / 2. In the same slide, the model // is rotated in bearings, so that the same movement of the bearing 6 corresponds to the same movement of the model //, and the workpiece is shaped by roller 5 of the lever 35 and 35. The pipe axis and the coordinated model // are rotated from the long shchestren 9, which is in engagement with shchestrenny 7 to 10 (fig. 1 and 2), the length of the pinion 9 corresponds to the maximum length of the object designed for processing on this machine, the length of the model stroke.

The gear P is rotated from the through shaft 26 and the pulleys 25, 24, 23, the latter of which is connected to the motor.

In pulley 23, a planetary gear is arranged using gears 19, 20, 21 and 22, by means of which shaft 14 receives one turn at 400 revolutions of pulley 25.

A shaft 12 is mounted on the shaft 14, bearing a finger / 5 for the fist groove on the drive drum 13. The drum / J receives rotation from the ratchet clutch 15. For manual adjustment of the machine, a worm clutch 17–16 and a right ratchet clutch / 5, sliding on the hub / 5, which sits on the key in the drum 13, rotating the latter freely on the shaft 14.

In the working cartridge 40, the pre-calibrated billet 45 is always pressed to one side of the slot with lever cam clips 43-43 by the action of a spring ring 41. A foot 44 under the spring ring 42 keeps the workpiece 45 from reverse shear during rapid rotation to the left behind the material of the cartridge 4.

The cartridge 4, which acts in the right side — on feeding the material, and in the left side — on sliding along the material, is also provided with a spring ring, the thickness of which makes it possible to adjust the sensitivity of the action of the cartridge.

For machining the earhook for spectacles, a drilling device acting from a pulley system is attached to the body / pad 38. The control of the feed of the drill and the ejection of the chips can be effected from an eccentric washer mounted on the end of the shaft 14 protruding from the housing, or by using linings and levers from the drum 13.

For easy handling of the machine when adjusting the case / opens on the hinge 30 (Fig. 2) together with the lid 28. To keep the workpiece 45 from lateral movements and accidental damage, a wooden tube 27 is moved back and forth from pin 6, to the back of which it is attached. To ensure a smooth product surface, the model //, the slide 12 and the driving drum 75 are enclosed in the / -2 casing while being protected from dust and shavings.

The turning of the workpieces is carried out with a through cutter 59 (Fig. 3), and the cut with a cutter 38,

Both the profiling (turning) and the cut are made by the action of a single lever 55; in the first case, from the roller 34 sliding over the copier //, in the second case from the cam 52 attached to the drum 75 at the end 55 of the lever 55 (FIG. 2).

The subject matter of the invention.

Claims (2)

1. A copy machine for the manufacture of products from celluloid and the like of materials, using a bearing roller and cutters of the balance bar, a drum with a grooves for the reciprocating movements of the workpiece and model from the shaft, and the planetary gear to the drum for reducing speed, characterized by the use of a mechanism for rotating and feeding the workpiece and a model consisting of a hollow cylindrical rod 5 (FIGS. 1 and 2) with a chuck 4 for receiving and clamping during the working movement of the workpiece 45, provided with a long keyway for the key 8 on the tubular axis 5 enclosing it, receiving, like the conventional model, rotation from the drive through the gears P 7, 10, which the rod 5 for feeding the workpiece is placed in the bearing 6, connected, like the bearings for the model 77, with a sled 72, bearing a finger 752 for the fist groove on the drive drum 75. 2. In the machine tool according to claim 1, the application on the tubular axis 5 of the chuck 40 (Fig. 1) with lever fists under the action of the spring rings 41 and. 42, clamps 43 serving to press the workpiece 45 against the walls of the hole for it in the cartridge and so arranged that they do not interfere with the advancement of the workpiece by its working movement by the lever cams of the cartridge 4, but prevent it from moving in the opposite direction when the cartridge 4 goes back idle, with what the cams on it should slide over the workpiece.
