Description

The handicraft production of spoons by hand means gives an extremely low productivity of labor. In order to mechanize the manufacture of spoons and increase productivity, it is known to use machine tools on which the workpiece passes successively a series of operations and at the end of the process takes the form of a spoon. In the known machines, the clamps for the blanks are placed on the drum receiving rotation, in order to communicate the blanks of rotation at the approach to the chisel cartridge forming them. In the proposed machine, the said clips are made in the form of tongs, the sponges of which receive movement from the rod carrying the center for setting the workpiece and entering the chopped end into the thread of the hollow axis rotating from the drive. The core and floor of the axis are placed inside the hollow shaft, which at the same time receives movement around its axis and, the axis of the drum located in the center of the machine bed, for the purpose of further supply of the workpiece, for the Next operations.:

In FIG. 1 shows a schematic side view of the machine; yg 2 - the same. front view; fchg 3- other-side, type of machine; FIG. 3 is a gear pattern for rotating the drum axis; FIG. 4 shows transmission schemes for communicating the rotation separately),. -: /: - :: -

The rotation of the axes of the proposed machine is communicated from the pulley 1-8 (Fig. 3), which in turn receives rotation from the drive. From pulley 18, rotation is transmitted via gear 19 to pulley 20 (Fig. 3S 4), from which rotation of wheels 6, 7, 7 and axes on which they are mounted is transmitted via a series of gears 23, 24, 25. On the axis 21 (Fig. 3), a knuckle disk 12 is mounted, the fist 12 of which acts on the crosspiece 13 mounted on the axis 11 of the drum in order to prevent periodic rotation. To ensure that the axle 11 is stopped at a certain place, a disk 16 is fitted on it, equipped with notches a into which the pawl 17 of the spring part 17 enters. The pawl 17 is withdrawn from the notch of the disk 16

the protrusion 22 of the disk 15, freely mounted nakos 11.

The workpiece, from which it is necessary to prepare a spoon, is placed on the platform 26, which is adjustable in height and inclination (Fig. 1), and enters the center 27 of the rod 30, which has been previously drilled in it. The rod 30 (Figs. 1, 5) is located inside the zero shaft 1 and with its cut end enters the thread of the axle 28, which receives rotation from the wheel 6 mounted on it. When the axis 28 rotates, the rod 30 connected simultaneously with the clamping jaws 31, made in the form of tongs, brings together (or moves apart) their ends, and 31 clamp (or free) lying on the square ke preform 26. Lips pressed By these 31, the workpiece rotates with the hollow shaft 1, and it is machined with a cutting head 32 (Fig. 3) into the mold 33 shown in Fig. 7

The hollow shaft 1 simultaneously with the rotation about its axis also receives rotation with the workpiece clamped on it near the axis 11 of the drum L, rotating with it (Fig. 2, 3). When moving the shaft 1 with the drum. And the fist 29 mounted on the shaft 1 for some time is directed by the arcuate part 29 of the machine bed, as a result of which the rotation of the shaft 1 stops for this period of time.

After the workpiece has been processed into the mold 33 - (Fig. 7), it is respectively rotated by the action of the load 34 (Fig. 1) and is fed to the internal surface of the scoop. The internal surface of the scoop is machined with a cutting head 44 while the workpiece, rotating with drum A, approaches the support 45 for its scoop. Proper shaping of the inner surface of the scoop is achieved by the fact that the support 45 and the cutting head 44 perform rocking movements when machining due to the action of an eccentric 43 (fug. 1, 3, 9) rotating with the axis 42 driven by the worm gear 40 ; 41 and the bevel gear 38, 39 from the axis 37, rotating, in turn, 6m of pinion 36, which is engaged with gear 19 (Fig. 3).

In processing the internal noeepXHOcsi scoop, the part of the spoon to be drawn into the scoop is released from the jaws with sponges 31, and the scoop enters: to the clamping jaws 56 (Fig. 6), similarly sponges of the jaws 31 and matching or moved by the stem 55 entering the hollow axis driven from the gear 51. The clamp df of the spoon scoop is under the action of spring pressure 58, 59 (Fig. 1C |, moreover, during rotations of the workpiece with fe, turning the scoop produces a cartridge 60, the axis of which is placed in frame B (Fig. 1) Frame B, in order to create a scoop for a spoon, П1 5л periodic oscillations from the drive — by means of the crank 63 (Fig. 3J, shatuna 62 and lever 61). The spoon in the peris (the processing, in addition to the jaws 56, is supported by an additional spring Podprom 46 (Fig. 1), which, when approached by the cartridge 60 part 64 is automatically retracted.

Rotation of the chester 51, sitting on the OSI; 54 of the clamping jaws 56 (Fig. 6), is coupled from bevel wheels 50 or 5 (Fig. 9) receiving rotation, and this line is from the axis 53, which engages with those of the Other wheel through part 4f, controlled by levers 48 affected by the cam disc 4f mounted on the axle 42.

The subject matter of the invention.
