Abstract

The invention relates to mechanical engineering and can be used, for example, in automatic lines for the manufacture of outer rings of ball bearings with an asymmetrically arranged raceway. The purpose of the invention is to increase reliability in operation by providing capture for the inner surface of the supplied parts. The loading device comprises a base in the form of walls. In the walls there are circular guides 5 and 6 facing each other, one end of each of which is arranged to mate with the receptacle 10 and the other with a tapping channel. The gripping mechanisms are made in the form of hooks 17 and 18 and are located along circular guides 5 and 6. The ring 19 rolls out of the supply tray into the slot 10. The hooks 17 and 18, rotating along the guides 5 and 6, enter the hole of the ring 19 Due to the asymmetry of the location of the inner ring groove, it is on the path of movement of one of the hooks. The part catches the other hook and moves along the ring guide to the receiving channel. Thus, in each channel, parts oriented along the groove location are provided. 5 il.

L / l3o6peteHHe relates to mechanical engineering and can be used, for example, in automatic lines for the manufacture of outer rings of ball bearings with asymmetrically arranged raceway.

The purpose of the invention is to increase the reliability of the device operation by providing gripping for the internal surface of the parts supplied.

Figure 1 shows the device, a general view; Fig. 2 is a view A in Fig. 1 (with the wall removed); on fig.Z - section BB in figure 1; figure 4 - section bb In fig. one; Fig. 5 shows the node I in Fig. 2 (at the time of the hooks approaching the ring). The parallel vertical walls 1 and 2, pressed with nuts 3 to the end projections of the stepped screws 4, form the base of the proposed device for feeding the rings. In walls 1 and 2 there are circular guides 5 and 6 facing one another, adjoining one another and ending with vertical straight-line sections. A supply tray 7 and two discharge channels 8 and 9 are fixed on the wall 2. A slot 10 is located behind the supply tray 7, which is attached to the wall 1. On opposite sides of the slot 10 in the wall 1, parallel rollers 12 and 13 are mounted on bearings 11. On BannK6v12, a gear wheel 14 is engaged. It is engaged with gear wheel 15 mounted on roller 13. Gear wheels 14 and 15 are identical to each other and are kinematically connected to engine 16. On roller 12, hook 17 is mounted, and hook 18 is mounted on a hook 13. Hooks 17 and 18 are rotatably mounted in Vertical, plane situated between the walls 1 and 2, the ends sblizhayuts above the nest 10 during rotation and are able to interact with. internal 0 surface located in the nest 10 of the ring 19, having an asymmetrically located internal annular groove.

The boot device operates as follows.

The extreme ring 19 from the supply tray 7 rolls into slot 10 and is located there, approach in the interface areas of circular guides 5 and 6 in walls 1 and

2. Turn on the engine 16, the rollers 12 and 13, which drive the multidirectional rotation, with the hooks 17 and 18 attached to them. The hooks 17 and 18 approaching each other.

friend, enter the hole of the ring 19 placed in the nest 10. With further rotation, the hooks 17 and 18 approach the inner surface of the ring 19. Because of the asymmetry of the internal annular groove, it appears on the path of the end of one of the hooks, which removes the surface of the ring 19. Therefore, that hook is in contact with the ring 19 in front of which the inner ring groove is not located. In FIGS. 1-5, the hook 17 is in contact with the ring 19, which lifts the ring 19 and winds it into a circular guide 5. The hook 18 leaves the revolving ring ring 19,

Do not come in contact with its surface. The ring 19 by the hook 17 is pulled along a circular guide 5 in the walls 1 and 2, turning 180 °. When a ring 19 hits a vertical linear

the hook 5 is guided out of the opening of the ring 19 and it falls into the discharge channel 8. During the movement of the ring 19 along the guide 5, the next extreme ring 19 rolls out of the inlet tray 7 into the slot 10. Then the work cycle repeats. Rings 19 are rolled along channels 8 and 9 with a strict orientation of the asymmetrically located inner annular groove.
