The invention relates to a device for automatically exchanging rotating parts, in particular rollers and sleeves of two-way roller bearings, bearing rings or rolling elements during their final processing,

It is known 3 times a load-carrying device, containing a base, a supply tray attached to it with a piecewise dispensing mechanism, two rollers mounted rotatably and forming a lodgment for the part in the machining area, a resetter made in the form of a tooth fixed on the rotation shaft of one of the rollers, a rotation drive and a diverting lotto (Nalov A, N. Loading devices for machine tools, M: Multinostroenie, 1972, s, 300, fig. 203),

A disadvantage of the known device is the impossibility of forcing parts onto rollers.

The purpose of the invention is to expand the functionality of the device.

FIG. 1 shows the proposed device, the axial section; FIG. 2 is the same longitudinal section.

The loading-load full-time device consists of a base 1, in which two shafts 2 and 3 are arranged in parallel with the possibility of rotation, at the free ends of which clips are located.

On the shaft 2 is located boot

the holder A with the pusher, made in the form of an emphasis 5, on the shaft 3, the unloading holder 6 with a tripper device, made in the form of a tooth 7, Both shafts 2 and 3 are equipped with eccentric pins 8 and 9, which are located on the tons g-e 10, as a result A mechanical bond is formed between the two shafts 2 and 3. On the last, respectively,

shakers) rollers 11 and 12, Shafts 2 and 3 are mounted to rotate in the housing of the spindle head 13,

The workpiece 14, for example, a double-bore ball hub sleeve, B, during processing, is drawn radially between the rollers II and 12 by the attractive force of the electromagnet 15, acting through the radial pole tip 16 and the axial pole tip 17. The inlet tray 18 is equipped with a piece delivery mechanism made in the form a shutter 19 rotatably mounted about an axis 20, the shutter 19 is provided with a roller 21 fixed on its free end, which cooperates with the anvil 5 rotating relative to the shaft 2. Once Trolley holder 6 is equipped with a movable element 23 for controlling the position of parts, performed, for example, in the form of a diaphragm, which serves to stop the optoelectronic circuit, and stop 22, which serves to control, or the sensor 25, the position of parts, or switch 2A, controlling the action of the micromotor 26. In the radial direction relative to the discharge casing 6 is the discharge tray 27.

Loading-loading device works as follows,

When the micromotor 26 is turned on, which drives the shafts 2 and 3, respectively, the sleeves 4 and 6 are rotated, the tooth 7 captures the machined part 14 located on the rollers P and 12 and feeds it to the discharge chute 27. At this, the stop 5 interacts with the roller 21, raises the flap 19 and the part 14 comes from the supply tray 18 to the rollers 11 and 12. At this point, the stop 22 turns on the switch 24, which gives the command

to reverse the movement of the micromotor 26, the clips 4 and 6 are returned to the initial position determined by the overlapping of the control element 23 and the sensor 25, the part 14 is machined. Then the cycle is repeated.
