Description

The technical solution relates to machine-tool construction, namely to devices for automatic loading of automatic technological machines and automatic lines with cylindrical parts with a pointed end.

Known hopper loading and orienting device containing a hopper formed by a shell and a base with an orienting receiver window made in the base, a rotating disk with gripping bodies made in the form of radial grooves (ed. USSR No. 921773. M. Cl. ³ B 23 Q 7/02. Bunker loading and orienting device / NI Soloviev, NP Solomin. Publ. 23.04.82. Bull. No. 15).

The disadvantage of this hopper loading and orienting device is the ability to orient only flat cylindrical parts with a conical chamfer at one of the ends.

Known hopper loading device containing a hopper formed by a shell and a base, a rotating disk with radial grooves ending in through-profile slots repeating the configuration of the external shape of the loaded parts, and a stationary copier installed in the upper part of the hopper (see in the book. Automatic loading systems for piece objects of processing into technological automatic machines: textbook / N.A.Usenko, V.V. Preis, E.V.Davydova, E.S.Bocharova; under the scientific editorship of V.V. -vo TulSU, 2013. p. 82, fig. 4.12).

The disadvantage of this hopper loading device is the complexity of its design, due to the high labor intensity of manufacturing a stationary copier and the need for manual individual adjustment of its profile for a specific loaded part and the peripheral speed of the rotating disk during assembly and adjustment of the hopper loading device.

The task of the technical solution is to simplify the design of the hopper loading device, which will increase the efficiency of its operation when loading cylindrical parts with a pointed end.

The specified technical problem is solved due to the fact that the hopper loading device for cylindrical parts with a pointed end contains a hopper formed by a shell and a base with an orienting receiver window made in the base, a rotating disk with gripping bodies made in the form of radial grooves ending in through profile nests that repeat the configuration of the external shape of the loaded parts.

What is new is that the parts of the through-shaped sockets, repeating the shape of the sharpened end of the loaded part, are directed towards the center of the rotating disk and have a depth h _k in the radial direction 10-20% less than the height h of the sharpened end of the part, parts of through-shaped sockets that repeat the shape of a cylindrical parts of the loaded part, made open towards the shell, the total depth l _{to the} through-shaped sockets in the radial direction is determined by the dependence l _to = (0.8-0.9) (l + h), where l is the total length of the part, width b of the orienting receiver window in the radial direction is 10-20% less than the length l _{c of the} cylindrical part of the part, determined by the dependence l _c = lh, while the distance c from the inner surface of the shell to the nearest edge of the orienting receiver window is 10-20% less than the height h of the pointed end of the part.

The essence of the technical solution is illustrated by drawings, where:

in fig. 1 shows a diagram of a hopper loading device in section along the axis of rotation of a rotating disk, general view;

in fig. 2 shows view A of FIG. one;

in fig. 3 shows a view B of Fig. one;

in fig. 4 shows a section along B-B of FIG. 3, illustrating the orientation in the receiving window of a part sunk into a through-shaped slot with a pointed end from the center of a rotating disk;

in fig. 5 shows a section along B-B of FIG. 3, illustrating the orientation in the receiving window of the part sunk into the through-shaped slot with the pointed end towards the center of the rotating disk.

The hopper loading device contains a hopper formed by a shell 1 and a base 2, a rotating disk 3 with gripping elements made in the form of radial grooves 4, ending with through-profile slots 5, repeating the configuration of the external shape of the loaded parts 6.

Parts K of the through-shaped sockets 5, repeating the shape of the pointed end of the loaded part 6, are directed towards the center of the rotating disk 3 and have a depth h _k in the radial direction 10-20% less than the height h of the pointed end of the part 6. Parts of through-shaped sockets 5, repeating the shape of the cylindrical part of the loaded part 6, are made open towards the shell 1, and their total depth l _k in the radial direction is determined by the dependence l _k = (0.8-0.9) (l + h), where l is the total length of the part.

At the base 2 of the hopper loading device, an orienting receiver window 7 is made. The width b of the orienting receiver window 7 in the radial direction is 10-20% less than the length l _{q of the} cylindrical part of part 6, determined by the dependence l _q = lh, while the distance c from the inner surface of the shell 1 to the outer edge of the orienting receiver-window 7 is 10 - 20% less than the height h of the pointed end of the part 6.

Hopper loading device operates as follows.

When rotating disc 3 rotates, parts 6, poured into the hopper, sink into the radial grooves 4, move and sink into the through-profile nests 5. Parts 6 sunk into the through-profile nests 5, during the rotation of the rotating disk 3, move to the upper part of the hopper, where parts 6, sunken with a pointed end to the center of the rotating disk 3, under the action of gravity move in the profile sockets 5 in the radial direction until their sharpened end is fully mated with the parts K of the through profile sockets 5, repeating the shape of the sharpened end of parts 6, since parts K are through profile sockets 5 have a depth h _k in the radial direction by 10 - 20% less than the height h of the pointed end of part 6. As a result, parts 6, sunk into the through profile sockets 5 with a pointed end from the center of the rotating disk 3, abut the ends of their cylindrical parts against the edge parts K through profile sockets 5, repeating the shape of the pointed end of parts 6, and remain in parts through profile sockets 5, repeating the shape of the cylindrical part of the loaded part 6, since the total depth l _{to the} through profile sockets in the radial direction is equal to l _to = (0.8-0.9) (l + h).

Further, all parts that have sunk into the through-profile slots, in the process of rotation of the rotating disk 3, move them over the orienting receiver window 7. Since the width b of the orienting receiver window 7 in the radial direction is 10-20% less than the length l _{q of the} cylindrical part of the part 6 , and the distance c from the inner surface of the shell 1 to the outer edge of the orienting receiver window 7 is 10-20% less than the height h of the pointed end of the part 6, then the parts that have sunk into the slots with pointed ends from the center of the rotating disk rest only on the outer edge of the orienting receiver windows 7, and the parts that have sunk into the slots with pointed ends to the center of the rotating disk, rest them only on the inner edge of the orienting receiver window 7. As a result, all parts sunk into the through profile slots, passing over the orienting receiver window, under the influence the forces of gravity are overturned by the ends of their cylindrical parts downward and are emitted in a vertical position into an external receiver (in Fig. unke not shown).

Thus, as in the prototype of the proposed technical solution, all the parts sunk into the through-profile nests, regardless of their initial position in the through-profile nests, are uniquely oriented in the bunker loading device, while there is no time-consuming stationary copier in the manufacture, requiring manual individual adjustment profile, greatly simplifies the design of the hopper loading device and increases the efficiency of its operation when loading cylindrical parts with a pointed end.
