Description

The invention relates to mechanical engineering and can be used to supply narrow cylindrical rings with a ratio of length to diameter of less than 0.25, as well as types of washers, plugs, plugs, valve seats, etc., to the machining area of a circular grinding centerless grinding machine. A loading device is known, which contains a magazine, a feed mechanism, a discharge tray with clamping elements at input 1. A disadvantage of the known device is the impossibility of ensuring reliable single-piece feeding of details such as narrow rings. The purpose of the invention is to increase the reliability of the device in operation when supplying parts such as thin rings. The goal is achieved by the fact that in a loading device containing a magazine, a feed mechanism and a discharge tray with pressure elements at the entrance, the feed mechanism is mounted with the possibility of reciprocating movement coaxially of the discharge tray. The arrow with a prismatic groove made on the shank from the side of the magazine, with the tip of the said arrow located on the side of the discharge tray. FIG. 1 shows the boot device, general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a cross-section of the FIG. four; in fig. 6 is a section DD-D in FIG. 5. The loading device for feeding narrow cylindrical rings contains a discharge tray 1, height-adjustable by supports 2 mounted on base 3. The gear 3, on which the magazine 5 is mounted, is attached to the base 3 by means of a bracket 6. A feed mechanism is mounted in the gear case 4 , made in the form of a pusher 7, equipped with a nozzle 8, which is made in the form of an arrow with a prismatic groove 9 on the shank and is installed with a tip in tray 1, and a bar 10 is mounted on the pusher 7 and the bar 10 System of adjustable cutters 12. The pusher 7 is pressed against the cylindrical copier 13, for example, with a spring (not shown). Above the outgoing chute 1 on the slats 14 with the possibility of adjustment, the upper knife 15 is installed by means of studs 16, and on the knife 15, above the entrance part of the tray 1, by means of the lugs 17 there is an elastic clamp made in the form of two bent flat springs 18 located symmetrically relative to the knife 15. The processing ring 19, when it enters the discharge tray 1, is pressed by an elastic clamp. From the discharge tray 1, the rings 19 enter the knife 20, where they are polished with a circle 21. Performing the nozzle in the form of a functional arrow ensures contact when pushed out at three points and makes it possible to lower the rear wall of the loading magazine to the center of the part located on the tray reciprocating pusher with a nozzle, which prevents the parts from falling back. The prismatic groove allows another ring to be in it in such a way that its cylindrical surface sinks lower than the cylindrical surface of a pushed ring, thus providing the possibility of an abutment of the upper end of a pushed ring to the lower end of the next one, which creates a stable position and prevents tilting back. The device operates as follows. Store 5 of ring 19 is fed from an elevator bin (not shown) and mounted one above the other by a column. From the gearbox 4 a reciprocating movement of the pusher 7 with the nozzle 8, which pushes the rings 19 out of the magazine 5, is performed by a copier. The next ring is lowered into the prismatic groove 9 of the nozzle 8. The ring 19 ejected into the tray 1 from above is pressed to the tray by curved springs 18, adjustable in height with paws 17, which prevents tilting forward. When returning the pusher 7 with the nozzle 8 to the initial position, the ring 19 can be tilted back as the nozzle leaves. But since the next ring 19 is already in the prismatic groove 9 of the nozzle, this will not occur, since the rear end of the ejected ring will be thrust into the front end of the next ring that is in the prismatic groove 9, as together with the pusher 7 it moves back and forth A bar 10 with a bar 11 carrying a system of adjustable slam 12 configured in such a way that they pass only one piece 19 from magazine 5, which is lowered into the prismatic groove 9 after the next one is pushed out. The use of the present invention improves the reliability of the device.
