Description

The technical solution relates to machine tool construction, namely to devices for automatically loading technological automatic machines and automatic lines with objects of processing the shape of bodies of revolution with implicitly expressed asymmetry of the ends.

Known bunker loading device for loading objects of processing the shape of bodies of revolution, containing a hopper and a rotating disk with protrusions forming nests for gripping processing objects (see in the book. Automation of press loading with piece blanks: / V.F. Preis, I.S. Blyakherov et al. M.: Mechanical Engineering, 1975. - 280 p., p. 88., Fig. 61).

The disadvantage of this bunker boot device is the inability to load objects of processing the shape of bodies of revolution with asymmetry of the ends and a height greater than the diameter, which significantly reduces the technological capabilities of the device.

Known bunker loading device for loading items of processing the form of bodies of revolution, containing a hopper formed by a shell and a fixed base, a rotating disk with through sockets, alternating with teeth to capture the items to be processed (see in the book. N.I. Kamyshny. Automation of loading machines. M.: Mechanical Engineering, 1977.- 288 p., Pp. 92-93, Fig. 84).

The disadvantage of this bunker loading device is a sharp decrease in its reliability and productivity when loading objects of processing the shape of bodies of revolution with implicitly asymmetric ends, one of which is cylindrical and the other asymmetric (conical, step or spherical), since such processing objects do not have a pronounced displacement of the center of mass along the longitudinal axis of symmetry.

The technical solution solves the problem of expanding technological capabilities, increasing the reliability and performance of the bunker loading device when loading objects of processing the shape of bodies of revolution with implicitly expressed asymmetry of the ends, one of which is cylindrical and the other asymmetric.

The specified technical problem is solved due to the fact that the bunker loading device comprises a hopper formed by a shell and a fixed base, a rotating disk with through sockets, alternating with teeth to capture objects processed by the shape of bodies of revolution with asymmetry of the ends, one of which is cylindrical and the other asymmetric .

What is new is that in the lower part of the hopper, on a fixed base under a rotating disk, an annular orientator is installed with a groove facing the through sockets of the rotating disk, while the groove cross section repeats the profile of the asymmetric end face of the workpiece, and the width of the upper part of the groove facing the through sockets, does not exceed the diameter of the cylindrical end of the subject of processing.

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

figure 1 shows a diagram of a bunker boot device in section along the axis of a rotating disk with sockets;

figure 2 shows an enlarged fragment I of the hopper boot device of figure 1;

figure 3 shows an embodiment of a ring orientator for objects with a conical or stepped end;

figure 4 shows an embodiment of the annular orientator for objects with a spherical end face.

The hopper loading device comprises a hopper formed by a shell 1 and a fixed base 2, a rotating disk 3 with through sockets 4, alternating with teeth 5 for gripping processing objects 8 of the shape of bodies of revolution with asymmetry of the ends, one of which A is cylindrical and the other B is asymmetric (conical, step or spherical).

In the lower part of the hopper, on a fixed base 2, under the rotating disk 3, there is an annular orientator 6 with a groove 7 facing the through sockets 4 of the rotating disk 3, while the section of the groove 7 repeats the profile of the asymmetric end B of the workpiece 8, and the width b of the upper part of the groove 7 facing the through sockets 4, does not exceed the diameter d _{1 of the} cylindrical end And the subject of processing 8.

For workpieces with a conical or stepped end, the cross section of the groove 7 is made in the form of a truncated cone, while the depth of the groove of the annular orientator

,

where l ₂ , d ₂ - respectively the length and diameter of the asymmetric (conical or stepped) end of the subject of processing.

For workpieces with a spherical end face, the cross section of the groove 8 is made in the form of a circle segment, while the depth of the groove

,

where r ₂ is the radius of the sphere of the asymmetric end of the subject of processing.

The distance m from the upper edge of the groove 7, facing the through sockets 4, to the upper edge C of the through socket 4

,

where l is the length of the subject of processing; α _bun - the angle of inclination of the fixed base of the bunker boot device to the horizontal.

Bunker boot device operates as follows.

When the disk 3 is rotating, the objects of processing 8, which are poured into the hopper, are agitated, poured and fall directly into the through sockets 4 or fall onto the teeth 5 and, turning around them, also fall into the through sockets 4.

Processing objects 8, sunk into the through holes 4 of the rotating disk 3 with the cylindrical end A down, rest on the upper edge of the groove 7 of the ring orientator 6, since the width of the upper part of the groove does not exceed the diameter d _{1 of the} cylindrical end A of the processing object 8. Processing objects 8, sunken into the through sockets 4 with an asymmetric end B are immersed down into the groove 7 of the annular orientator 6, since the cross section of the groove repeats the profile of the asymmetric end of the workpiece.

Processing objects 8, sunk into the nests, are moved by the rotating disk 3 to the upper part of the hopper, where the processing objects sunk into the through holes 4 with the cylindrical end A down and resting on the upper edge of the groove 8 of the ring orientator 7, overturn around the upper edge C by gravity through the socket 4 and fall back into the hopper, and the objects of processing 8, sunken down by the asymmetric end B and immersed in the groove 7 of the ring orientator 6, are held in it, leaning on the upper edge C of the through socket 4, and move 3-rotating disk in dispensing processing objects from zone 8 through slots in the receiver 4 (Fig. not shown).

Thus, the proposed technical solution solves the problem of expanding technological capabilities, increasing the reliability and productivity of the bunker loading device when loading objects of processing the shape of bodies of revolution with implicitly expressed asymmetry of the ends, one of which is cylindrical and the other asymmetric.
