Description

The invention relates to the field of mechanical engineering, in particular to the machine-tool industry, and can be used for the oriented supply of parts such as bearing rings in automatic machines.

A device for feeding parts, containing a supply tray, transporting a sprocket, a plate mounted on one side of the sprocket with spring-loaded pushers arranged coaxially with the sprocket and cooperating with a stationary copier, and the feeding tray [1].

Such a device does not provide oriented iodachi parts with a tapered or stepped bore, for example, oriented feed to the machining machines of the outer rings of tapered roller bearings.

The closest in technical essence to the proposed is a device for feeding parts with a conical or stepped hole, containing a disk with holes placed coaxially with the sockets of the sprocket adjacent to the disk. In the disc holes are arcuate thrust beads, and the pushers are located2

coaxial sprockets and disk openings are in the form of discs with a diameter smaller and larger than the smaller hole diameter of the part, as well as a segment cut against the stop shoulder.

The disadvantage of this device is the ability to skew parts when advancing the sprocket from the slot and through the holes of the disk, which leads to the closure of parts in the holes of the disk and the breakdown of the drive mechanism of the pushers.

The aim of the invention is to improve the reliability of the device in operation.

This is achieved by the fact that in the proposed device containing a feed and discharge trays, transporting an asterisk, a disk with an

Holes ¹⁵ arranged coaxially jacks and axial cylindrical bore, the diameter of which exceeds the diameter of the disk center hole circle, and a plate on which are arranged coaxially jacks asterisk ki spring loaded plungers _20, interacting with the fixed cam, wherein

The discharge tray has two receiving funnels opposite the disk, one located at the periphery of the disk and the other in its cylindrical bore, on the pushers there are valves installed in the form of disks placed coaxially and parallel to the working parts of the pushers and having a diameter smaller than the outer diameter of the part larger bore diameter details. The distance between the working part of the pusher and the valve installed on it should not be less than the width of the part, and the receiving funnel of the discharge tray, located at the periphery of the disc, should be installed in the same plane with the feed tray.

FIG. 1 shows the proposed device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 3; in fig. 5 is a section of YYD in FIG. four.

The device contains a rotating shaft 1, on which plates 2 and 3 are fixed with pushers 4, an asterisk 5 with sockets 6 and a disk 7 with holes 8. The sockets 6 in the asterisk 5, the holes 8 in the disk 7 and the pushers 4 in plates 2 and 3 are aligned . On the pushers 4, the valves 9 are rigidly fixed. To actuate the pushers 4, rollers 10 are mounted on them, which with the help of springs 11 are pressed against a copier 12 fixedly mounted on the housing 13. In the disk 7, slots 14 are made along its periphery clamps 15, partly included in the hole 8. The shutters 9 are made in the form of discs and fixed on the pushers 4 and coaxially last with the help of terminals 16 and 17 and the rod 18. The diameter of the shutters 9, made in the form of a disc, is smaller than the outer diameter of the parts and larger and opening parts. The working part 19 of the valve 9 is parallel to the working part 20 of the pusher 4 and at a distance not less than the width of the part or the width of the socket 6 of the asterisk 5. The diameter of the working part 19 of the pushers 4 is smaller and larger than the smaller diameter of the hole of the parts.

For supplying parts to the sockets 6, the sprocket in the device has a feed tray 21, and for outputting the oriented parts from the device there is a discharge tray 22 with receiving funnels 23 and 24. The receiving funnel 23 is located in an axial cylindrical bore 25 made in a disk 7 and having a diameter exceeding the diameter of the centers of the holes 8 of this disk. Another receiving funnel 24 is installed at the periphery of the disk 7 in the same plane with the feed tray 21.

The device works as follows.

Parts arriving through the feeding tray 21 are not strictly oriented, i.e. their wide and narrow ends are located in

four

molasses details arbitrarily. On the feeding tray 21, the parts enter the groove between the disk 7 and the plate 2. When the asterisk 5 rotates, the parts that enter the groove between the disk 7 and the plate 2 sink into the slots 6 and the stars 5 are located between the working cavity 19 of the valve 9 and the working part 20 of the pushers 4. With the passage of parts above the funnel 23, the pusher 4 with the flap 9 moves along its axis by a certain amount, keeping the position of the parts. The part facing the pusher with its wide end moves from the nest 6 into the hole 8 to such an extent that its end faces the end of the cylindrical bore 25 and falls into the funnel 23. If the part faces the pusher 4 with its narrow end, it moves to a smaller the magnitude is held in the hole 8 by the spring clamp 15. Next, the pusher 4 returns to its original position, and the flap 9 mounted on the pusher 4 moves the part again from the hole 8 to the nest 6 of the sprocket 5. Then the part reaches the receiving funnel 24 falls out under the action of its own weight from the nest 6 asterisks 5 into the receiving funnel 24. As a result, the rings of the corresponding orientation enter the funnels 23 and 24.

The proposed device provides a reliable oriented supply of parts with a tapered or stepped hole due to the fact that during transportation and reorientation of parts are kept from unwanted distortion.
