tirovke goods with any surface shape. The aim of the invention is to improve reliability of operation. Vacuum lifting device contains Traverses I fixed in through-holes I by means of clamps, at the end of each of which suction 8 is installed with a ball joint 7. The other end of grips is connected to a vacuum collector. The invention relates to mechanical engineering and can be used in assemblies, robots handles tori, transport devices, auto operators and other areas of national economy during transportation of goods with any surface shape.

The aim of the invention is to increase the reliability of operation.

Figure 1 shows the vacuum lifting device, section; figure 2 - vacuum gripping body, section.

The device includes a housing 1, which is simultaneously simultaneously with a vacuum manifold, on which using clamps consisting of split sleeves 2 and nuts 3 are fastened. The grippers are made in the form of telescopically connected glasses: internal 4 and external 5. There are holes in the ends of the glasses. A spring 6 is located between the cups. A vacuum suction cup 8 is attached to the bottom of the cup 5 through a ball joint 7. In the cup 5 there is a ball 9 capable of free movement. The diameter of the ball 9 is chosen so that, free moving inside the glass 5, it cannot fall out of it. To hold the glass 5 in the glass 4, a pin 10 is inserted into the cylindrical wall of the glass 5, and a corresponding groove is made in the wall of the glass 4. Another constructive solution is also possible, limiting Djee to the loss of glass 5 from glass 4. For example, on the outside of the cylindrical surface of the glass 5 and on the inside of a cylindrical pore. The grippers are made in the form of telescopically connected spring-loaded glasses 4 and 5 with openings in the ends with restriction of the course of one relative to the other. Inside one of the glasses, a ball 9 is freely positioned, blocking the access of vacuum through the hole in the end of the glass in case of non-suction of the grip to the surface of the part. 2 Il.

The surfaces of the cup 4 can be provided with annular collars. Casa smiling, the flanges restrict the movement of glass 5 in glass 4.

For better fixation of the ball 9 in the hole in the end face of the glass 5, the hole is made conical.

The device works as follows.

The housing I is lowered onto the part by means of a lifting and transport device (not shown). As the suction cups are lowered, they touch the surface of the part with the help of a hinge 7 and

the account of its own flexibility and elasticity is oriented normal to the surface, i.e. occupy a position in which the suction works most efficiently.

Upon further lowering of the housing 1, the cup 5 moves in the cup 4, compressing the spring 6. After all the suction cups are pressed against the part, it stops moving down; In the vacuum manifold 1, a vacuum is created, thanks to which the suction cups 8 engage with the part.

If for any reason a clutch occurs (suction gets 30 into the hole, at the hole, at the groove, at the crack, on the heavily polluted surface, etc.), the air flow, through the suction 8 into the glass 5, carries with a ball 9 and presses it to the hole in the end face of the glass 5, thereby terminating the flow of vacuum. Then the cup 5, together with the suction cup 8, overcoming the action of the spring 6, rises in the cup 4, thereby showing the lack of adhesion of this suction cup,

with detail. The worker controlling the hoisting-and-transport mechanism receives the most important information on how many suction cups are attached to the part surface and where the uncoupled ones are. Such visual inspection allows the worker to make an objective decision about the possibility of lifting and transporting the part. Eating the number of suction cups attached to the part or their location does not provide reliable lifting and transporting of the part, the worker releases the vacuum without testing the possibility of lifting and after eliminating the causes of non-adherence of the suction cups with the part repeats the capture.

The presence of the hinge 7 makes it possible to increase the range of degrees of freedom of the suction cup 8. This is especially necessary when capturing parts with a surface that has sharp curvature differences.
