Description

The invention relates to devices for centering churaki when they are fixed on the centers of a shelling machine using chucks. In the proposed arrangement, the tongs are placed on the ends of the bed and their sponges are equipped with toothed sectors, which, for the purpose of rotating the tongs of the tongs, are communicated by means of a hydraulic transmission or gears and a friction clutch, rotation from the motor. The same motor communicates the axial movement of the spindle and the machine bearing the centers, and the specified axial movement or launch of one or the other tongs can be carried out either in conjunction with each other or independently of one another.

In FIG. 1 is a side elevational view; FIG. 2 is a sectional view taken along line AB in FIG. one; FIG. 3 is a section through the line CD in FIG. one; FIG. 4 is a top view of the device; FIG. 5 is a longitudinal section through a part of the fixture serving for axial movement of the spindles; FIG. b - longitudinal section of the modified device; FIG. 7 is a cross section of it; FIG. 8 is a view of the modified device from above with a partial section.

The proposed device is equipped with tongs to capture churakov

(Fig. 1-4) with jaws located at the ends of the shelling machine for each end of the block separately. The jaws 7 and 2 of the mites have axes 3 in the frame of the machine itself, fixed within frame 4. At the ends of axes 3, jagged sectors 5 are interlocked, interlocking one with the top and the other with the bottom interlocking gears 6 freely rotating on the axis x 7. On the elongated sleeve of the lower gear b, a worm wheel 8 mounted on the key is driven by screw 9. This screw 9 (Fig. 5) is hollow and rotates in bearings 70, and at the end of screw 9 a casing of a friction clutch mounted on 7 discs 72, with friction material 73. Internal 74 of the coupling is also provided with disks and mounted on a key on the axis 75, informing axial movement of the bearing centers of the spindle and the machine. The coupling strength of the coupling parts is controlled by the spring 76 and nut 77,

Axis 75 is located inside screw 9 and is driven into rotation by sprockets 78 and 79 (Figs. 1-4), the latter of which receives rotation from an electric motor, through one of the known gears. The axle 75 feed in the axial direction is switched off by a disk friction clutch 20, by means of a lever 27, which is freely rotatable

tube 25. Levers 22 and 23 serve to turn on the sleeves of the right and left devices and fit one on the inner roller 2 and the other on the tube 25 covering the roller 24. When the device is working, you can use the levers 21, 22 and 23 to turn on or off tongs, or others, or both, at the same time in connection with the axial movement of spindles or separately from it. When turning on the axial feed of the spindles, both of the levers 22 and 23 of the devices are locked, and when one of the devices is turned on or both, the axial feed of the spindles is locked.

Before feeding churakoe to the centers of the machine, they are located on rollers 26 in order to bring the curves of churacs with curvature in the same plane before being grabbed down by the tongs. The length of the jaws of the tongs / and 2 is chosen such that the centering of both ends occurs at the most advantageous section.

The described device can be modified, and the hydraulic gear is used instead of a worm gear to turn the jaws and / and 2 ticks (Fig. B-8). In this case, the gear 36 is alternately mounted on the elongated sleeve of the upper gear 6 and alternately coupled with the gear racks connected to the plungers 27 and 28 located in the common cylinder 2P and the flanges 30 and 31 that are guided during their movement. The plungers are controlled by a flywheel 33 and a distribution spool 34 with cuffs 55. The plungers are controlled by conventional throttle valves.

The subject matter of the invention.

Claims (3)

1. A device for centering the pellets when they are fixed on the centers of a shelling machine with the use of pincers to grip the pellets, characterized in that the jaws / and 2 ticks have axes in the frame of the machine itself, are placed on either end of it and are equipped with toothed sectors 5, which via gears 6, 8, 9 and friction clutch / 7, rotation through axis / 5 is communicated from the motor, which informs axial movement of the bearing centers of the spindle and the machine, which device is designed to set in motion or turn off either some pliers or others, or both are simultaneously connected with the axial movement of the spindles or separately from it. 2. When fitting in accordance with claim 1, use rollers 26 for placing churacs on them before feeding them to the centers of the machine in order to bring the curves of the churacs before taking them with tongs in a hump down position. 3. A variation of the tool according to claim 1, characterized in that to rotate the jaws, instead of a screwdriver, a hydraulic transmission is used, consisting of plungers 27, 28, equipped with gear racks that engage alternately with gear wheel, mounted on the bushing of the gear wheel 6.
