Description

The invention relates to the mechanization and automation of technological processes and can be used for the piece delivery of flat blanks from the hopper to presses or other processing machines.

The purpose of the invention is the expansion of technical capabilities by providing orientation of the seized billet.

Fig, 1 shows a gripping organ, a longitudinal section; FIG. 2 is a section A-A in FIG. 1;

The gripping body comprises a housing 1, made in the form of a tube with a cavity (channel) 2 for communication with a vacuum source and a flat end 3 for contact with the workpiece 4, on which the workpiece 5 is located in the placer of the workpieces 6, Rods located around the center of the flat end of the case 7, on which the springs 8 are worn. The rods are movable in the holes made in the threads 9. The springs 10 are pressed against the body and by means of the axes 11 are pivotally connected to the sleeve -12, the movable body of the body with the possibility of contact with the stop 13, fixed to case. The arms 14 are fastened on the ends, axles 15 are attached to the ends of the slats on the side of the body; rollers 16 are hinged to it, contact the side surface of the copier 17 moving along the body and spring 18 pressed to the body in the direction of a flat flat end ; enclosures.

The side surface of the copier is made of a combination consisting of cylindrical surfaces 19 and 20 and the surface 21 of a truncated Koiryca located between them with the lower location of the smaller base. The bases of the truncated cone are coupled with cylindrical surfaces. The copier is fixed to the holder 22, which is movable in the guides 23. A through groove 24 is made in the holder. Placing one of the rigs in the through groove of the holder ensures that the hinges are rotated in the horizontal plane of the sleeve.

Gripping body works as follows.

The gripping body is depicted at the time of work when the end of the 3 body I is in contact with the workpiece 4, is located

in the placer blanks 6, the roller 16 is pressed against the cylindrical lateral surface 19 of the copier 17 with the forces generated by the springs 10, the rods 7 with the squeezed rods of 8 are in contact with the lower ends with the scattering of the blanks.

When moving down from the indicated position of the holder 22, the copier 17 begins to move downward, compressing the spring 18. At this, the rollers 16, having passed the cylindrical surface 19 of the copier 17, begin to move along the conical surface 21, as a result of which the ha 9, overcoming the forces of the springs 10, begin to rotate around the axes 11, thereby removing the rods 7 from the flat end 3 of the housing 1, Since the workpiece 4 is pressed by the loaded end 3 of the housing 1, the movements of the rods 7 do not cause the movements of the workpiece 4, however, the indicated movements of the rods remove the work 5 Other parts located on the workpiece 4 To reduce the frictional forces of the rods 7 on the workpiece 4, the ends of the rods should be polished or equipped by rolling with balls. By the end of the rod travel, the workpiece 5 is removed from the workpiece A, and the right rod 7 is lowered by its end below the upper plane of the workpiece 4, the rollers 16 are in contact with the surface 20 of the copier 17, and the springs 10 develop the greatest effort.

Then the holder 22 begins to lift upwards, as a result of which the rollers 16, having traversed the surface 20, begin to move along the surface 21, moving the rods 7 to the end 3, which rotate around the axes 11 ti 9, and the right rod 7 comes in contact with the face billet 4 and with further movement moves the billet 4 to the end 3 of the corpus 1 due to the fact that the friction force between the end 3 and the surface of the workpiece 4 menip the workpiece 4 shifting the force created by the springs 10 and transmitted to the rod 7 by turning t 9 g,

Having passed the surface 21, the rods 7 are returned to their original position by moving the workpiece 4 to a position in which it completely closes the channel at the end 3.

mind, resulting in the workpiece 4 reliably pressed against the end 3. Starting from this moment of work, the rollers 16 are only in contact with the surface 19 of the copier 17. With the further rise of the holder 22 upward the spring 18, unclenched, holds the end 3 in contact with aarotoBKoft 4. The copier 17, having passed upward segment o (comes with the sleeve 12 into contact, after which the lower ends of the rod 7 begin to rise upwards relative to the still housing 1. With a further rise on segment b, the copier 17 rises only together with the sleeve 12, tagami 9 and rods 7

Then the sleeve 12 comes into contact with the stop 13, after which the rods 7, the body 1 and the workpiece 4 begin to rise upwards from the copier 17, while the lower ends of the rods are located above the end 3, and therefore they do not interfere further in the process of orientation of the workpiece at the end 3 which is carried out by the forced shift of the workpiece 4 in the plane of the end 3.

Next, the workpiece 4 is transported to the zone of action of the orienting strips (not shown), undergoes the process of orientation, and is then fed to the working position, where it is separated from the end 3 by separating channel 2 from the vacuum source. Thereafter, the gripping organ is brought into contact with a scattering of blanks by the end face 3 from the holder 22, and the process of regularized gripping of the next blank is repeated.

The invention allows for the gripping and orientation of the workpiece on the gripping body with a single drive element.
