Description

The utility model relates to machine tool building, namely to devices for automatic loading of technological automatic machines and automatic lines with volumetric blanks with asymmetry along the ends, used, for example, in technological operations of pressure treatment.

Known disk gear hopper loading device containing a hopper formed by the shell and the base, a rotating disk with gripping bodies made in the form of through sockets, alternating with protruding teeth, and radial grooves extending from the center of the disk to the sockets (see in the book. Systems of automatic Usenko N.A., Preis V.V., Davydova E.V., Bocharova E.S., scientific editor V.V. Preis, Tula : TulGU Publishing House, 2013. pp. 78-80, Fig. 4.10).

The disadvantage of this hopper loading device is the impossibility of loading bulky workpieces with asymmetry at the ends, the height of which is not more than 1.5 times their outer diameter.

A bunker loading and orienting device is known, containing a bunker formed by a shell and a base, a rotating disk with gripping elements made in the form of radial grooves made with a slope directed towards the periphery of the rotating disk (ed. mon. USSR No. 921773. M. Kl. ³ B23Q 7/02.

Bunker load-orienting device / N.I. Solovyov, N.P. Solomin. Published 04/23/82. Bull. No. 15).

The disadvantages of this bunker loading and orienting device is its low reliability when loading bulk billets, the height of which is not more than 1.5 times their outer diameter, having a pronounced asymmetry at the ends, for example, a stepped shape with different outer diameters at the ends.

The objective of the technical solution is to increase the reliability of the bunker loading and orienting device when loading bulk billets, the height of which is not more than 1.5 times their outer diameter, which have a pronounced asymmetry at the ends.

The specified technical problem is solved due to the fact that the hopper loading and orienting device for bulk workpieces with asymmetry at the ends contains a hopper formed by a shell and a base, a rotating disk with grippers in the form of radial grooves made with a slope directed towards the periphery of the rotating disk.

What is new is that on the periphery of the base, along its circumference, an annular groove is made facing the rotating disk with gripping elements in the form of radial grooves, while the width of the annular groove corresponds to the depth of the radial grooves in the direction towards the periphery of the rotating disk, and the depth of the annular groove changes smoothly from the maximum value in the lower part of the bunker, not exceeding half the height of the bulk billet with asymmetry along the ends, to zero value in the upper part of the bunker.

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

in fig. 1 shows a diagram of a bunker loading and orienting device for bulk workpieces with asymmetry along the ends in a section along the axis of rotation of a rotating disk, general view;

in fig. 2 shows fragment I of FIG. 1;

in fig. 3 shows view A of FIG. 1;

in fig. 4 shows fragment I of FIG. 1, illustrating the position in the radial groove in the lower part of the hopper of a bulk billet with asymmetry along the ends, sunk with the end of a smaller diameter up;

in fig. 5 shows fragment I of FIG. 1, illustrating the position in the radial groove in the lower part of the hopper of a bulk billet with asymmetry along the ends, sunk with the end of a smaller diameter down;

in fig. 6 shows a section along B-B of Fig. 3, illustrating the position in the radial groove in the upper part of the hopper of a bulk billet with asymmetry along the ends, sunk with the end of a smaller diameter upwards;

in fig. 7 shows a section along B-B of Fig. 3, illustrating the removal from the radial groove in the upper part of the hopper of a bulk billet with asymmetry along the ends, sunk with the end of a smaller diameter down.

The bunker loading and orienting device for bulk workpieces with asymmetry along the ends, contains a bunker formed by a shell 1 and a base 2, a rotating disk 3 with grippers in the form of radial grooves 4, made with a slope 5 directed towards the periphery of the rotating disk 3. On the periphery base 2 along its circumference, an annular groove 6 is made, facing the rotating disk 3 with gripping elements in the form of radial grooves 4, while the width a of the annular groove 6 corresponds to the depth h of the radial grooves 4 in the direction towards the periphery of the rotating disk 3, and the depth H of the annular the groove 6 smoothly changes from the maximum value in the lower part of the hopper, not exceeding half the height h _c of the bulk workpiece 7 with asymmetry at the ends, to zero in the upper part of the hopper.

Bunker loading and orienting device for bulk workpieces with asymmetry at the ends works as follows.

During the rotation of the rotating disk 3, volumetric blanks 7 with asymmetry along the ends, filled into the bunker, fall into the radial grooves 4 and move them to the upper part of the bunker.

Volumetric workpieces 7 with asymmetry along the ends, sunk into the radial grooves 4 with the end of a smaller diameter up, are held in the radial grooves 4, moved by a rotating disk 3 to the receiving window (not shown in Fig.) and are issued from the hopper loading-orienting device.

Volumetric blanks 7 with asymmetry along the ends, sunk into the radial grooves 4 with the end of a smaller diameter down, under the action of gravity G fall out of the radial grooves 4 back into the hopper.

Thus, this technical solution will increase the reliability of the bunker loading and orienting device when loading bulk billets, the height of which is not more than 1.5 times their outer diameter, which have a pronounced asymmetry at the ends.
