Description

Bunker loading device for blanks with a cylindrical shape of one of the ends and a conical shape of the other

The technical solution relates to machine tools, namely to devices for automatic loading of technological automatic machines and automatic lines with rod blanks of the form of bodies of revolution, one of the ends of which is made conical.

Known bunker loading device for orienting piece of rod blanks in the form of bodies of revolution, one of the ends of which is made conical, containing a hopper formed by a shell and a fixed base, a rotating disk with gripping bodies made in the form of radial grooves, turning into through slots having a shape corresponding to the profile of the longitudinal section of the workpiece (see in the book. A. Malov. Automatic loading of metal-cutting machines / A. N. Malov. - M .: Mashgiz, 1955. p. 124, Fig. 90).

The disadvantage of this bunker boot device is the low reliability of orientation of the rod blanks in the form of bodies of revolution, one of the ends of which is made conical.

Known bunker loading device containing a hopper formed by a shell and a fixed base, a rotating disk with gripping bodies made in the form of radial grooves evenly spaced around the circumference, turning into through holes, a ring mounted in the lower part of the hopper on a fixed base, having an annular groove, the cross-section of which corresponds to the profile of the conical end face of the workpiece (Patent No. 64977 of the Russian Federation. IPC 6 B23Q 7/02. Bunker loading device / Preis V.V., Davydova E.V. Publish. 07.27.2007. Bull. No. 23. II h. )

The disadvantage of this bunker boot device is the complexity of its design, as well as the high complexity of manufacturing a rotating disk and its assembly in the bunker boot device.

The objective of the technical solution is to simplify the design of the bunker boot device and reduce the complexity of manufacturing a rotating disk and its assembly in the bunker boot device.

This technical problem is solved due to the fact that in the bunker loading device for blanks with a cylindrical shape of one of the ends and a conical shape of the other, containing a hopper formed by a shell and a fixed base, a rotating disk with gripping bodies made in the form of radial grooves evenly spaced around the circumference, passing into the through sockets, a ring mounted in the lower part of the hopper on a fixed base, having an annular groove, the cross section of which corresponds to the profile of the con Cesky end preform formed through rectangular slot open to the side faces of the ring, said annular groove is located opposite the open ends of through slots and the rotating disk is formed with an outer diameter smaller than the inner diameter of the ring.

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

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

in FIG. 2 shows a fragment I of the device, enlarged;

in FIG. 3 is a view A of FIG. one;

in FIG. 4 depicts the preaching of a workpiece into a through slot of a rotating disk with a conical end face forward;

in Fig. 5 depicts the retraction of the workpiece into the through slot of a rotating disk with a cylindrical end face;

in FIG. 6 depicts the loss of a workpiece sunk by a cylindrical end from a through socket in the upper part of the hopper;

The bunker loading device comprises a hopper formed by a shell 1 and a fixed base 2, a rotating disk 3 with gripping bodies made in the form of radial grooves 4, turning into through sockets 5, having a shape corresponding to a longitudinal section profile

blanks 6. In the bottom of the hopper, on a fixed base 2, a ring 7. is installed. An annular groove 8 is made on the inner side of the ring 7, the cross section of which corresponds to the profile of the conical end face of the blank 6. The through sockets 5 are made rectangular with the ends open towards the ring 7, the outer diameter D _{d of the} rotating disk 3 is less than the inner diameter D of _the ring 7.

The described hopper boot device operates as follows.

When the rotating disk 3 rotates, the workpieces 6, filled in the hopper, fall into the radial grooves 4 and move towards the through holes 5. If the workpiece 6 moves toward the through slot 5 with a tapered end, then it sinks into the through slot 5 completely, since the transverse the cross section of the annular groove 8 corresponds to the profile of the conical end face of the workpiece 6. If the workpiece 6 moves towards the through socket 5 with the cylindrical end forward, then it does not completely fall into the through hole 5, since it rests on the upper end of the cylindrical end Part 9 of the groove 8, and a conical end - on the edge of the through slot 5.

With further rotation of the rotating disk 3, the workpieces 6 are moved to the upper part of the hopper. The workpieces 6, not completely sunk into the through holes 5, drop out of them under the influence of gravity back into the hopper. The blanks 6, completely sunk into the through holes 5, are moved by the rotating disk 3 to the discharge window (not shown in FIG.) Through which they drop out into the receiving tray (not shown in FIG.).

The implementation of through sockets 5 rectangular with the ends open towards the ring 7 greatly simplifies the design of the rotating disk 3 and reduces the complexity of its manufacture, and the execution of the outer diameter D _{d of the} rotating disk is less than the inner diameter D _{to the} ring, greatly simplifies the assembly of the rotating disk in the hopper loading device, since does not require disassembly of the ring, which together simplifies the design of the bunker boot device.
