Abstract

The invention relates to mechanical engineering, namely to the grippers of manipulators, and can be used for carrying out various technological operations with blanks of various shapes. The purpose of the invention is to expand technological capabilities and increase reliability by ensuring the capture of one flat billet with holes. The device comprises a housing consisting of two parts. In the upper part 2 is placed a spring-loaded rod of the power cylinder and spring-loaded rollers 6. Through the latter, the rod having a conical inlet part acts on the gripping bodies 11 located in the groove of the lower 3 part of the body. The parts are interconnected by rollers 6 and spring-loaded guides 16. At the end of the lower 3 part of the housing there are stops, made in the form of adjusting screws 13 with nuts 14. The end of screws 13 below the ends of the gripping bodies is the thickness of the workpiece to be captured. 2 Il.

The invention relates to mechanical engineering, namely to the grippers of manipulators, and can be used for carrying out various technological operations with parts.

The purpose of the invention is to expand technological capabilities and increase reliability by ensuring the capture of one flat billet with a hole - .Q mi.

Ka figure 1 shows the gripper, a general view; fig 2 - section aa in figure 1 „

The grip comprises a housing 1 consisting of upper 2 and lower 3 parts. c. In case 1, a spring-loaded rod 4 with a seal 5 is placed. The rod 4 is provided with a conical feed-in part with the possibility of acting on rollers 6, stepped in shape. jn The rollers 6 are spring-loaded with rod-shaped 7. On the rollers 6, grooves 8 are made, by which they move along bars 9 secured with screws 10. In the lower part 3 of housing 1, 25 grooves are made, along which the gripping members 11 move. slopes 12 are made, directed away from the axis of the cage, which ensures the capture of a flat Q blank beyond the edges of the holes.

In the lower part 3 end stops are installed, made in the form of adjusting screws 13 with nuts 14, the ends of which are lower than the ends of the gripping bodies on the thickness of the workpiece.

The lower part 3 is spring-loaded relative to the housing 1 by springs 15 mounted on the guides 16. In this case, the gripping bodies 11 are able to move relative to the rollers 6, which compensates for the error in the feed of the blanks.

The device works as follows.

Before operation, the gripping bodies 11 and the adjusting screws 13 with nuts 14 are adjusted to the thickness of the supplied workpiece.

Claims (1)

Further, when compressed air is supplied to the power cylinder, the rod 4, moving to the left, with its conical part acts on the rollers 6, which, in turn, act on the gripping bodies 11 and move them apart. In so doing, the lower ends of the gripping bodies abut against the edges of the upper preform and the preform is gripped. When the stem 4 moves to the right, the rollers 6 under the action of the spring 7 move, move the gripping bodies 11 inside and the workpiece falls into the die matrix. The cycle is repeated. The formula was invented and the Seizure, comprising a housing, gripping bodies installed in the housing, the lower ends of which are made with inclinations directed from the gripper axis; end stops, different from the fact that, in order to expand technological capabilities and increase reliability by ensuring the capture of one flat billet with holes, the body is made of two tays interconnected by step-shaped rollers and spring-loaded guides, the lower part of the body has a groove, gripping bodies are installed in the lower part of the body with the possibility of horizontal movement in the latter, and the end stops are installed in the lower part of the body with the possibility of adjustment in the vertical plane.
