Abstract

The invention relates to devices for gripping articles with a hole. The purpose of the invention is to simplify the design. The device comprises a ram cylinder comprising a body I with a lid 2, a piston 3 and a brush 4, a return spring 5, a carrier element 6 attached to the brush 4, gripping elements 7 connected by means of 13 13 with hinges 8, 9 and 9 hinges 4, and through the axes 11, placed in the grooves 12 of the cover 2, with the body 1 of the power cylinder. The carrier 6 is connected to the lifting mechanism 14. When the working pressure is supplied to the upper cavity of the ram, the housing 1 moves upwards and the gripping elements 7 to each other. In this position, the device is introduced into the cavity of the product 15. Then the pressure in the upper cavity of the ram is discharged, the housing 1 moves downwards, and the gripping elements 7 are diverted to the side against the walls of the product 15. Next, the mechanism 14 lifts the device along with product. Release of the device from the product is carried out simultaneously with bringing the device to its original position. 2 Il.

Description

 This invention relates to a lifting and transport equipment.

The purpose of the invention is to simplify the design.

FIG. 1 shows the capture in the original field: ogene; in fig. 2 - the same as in the work;

j The gripper contains an actuator in the form of a force cylinder, including a housing 1 with a roof 2, a piston 3 with a brush 4 and a returnable barrel 5, a carrier element 6 attached to the rod 4, and gripping elements 7, each of which has one end Brightly fixed to the body 1 s. the possibility of radial movement, and the middle part by means of the hinges 8, t g 9 and the hinges O - to the rod 4. To obtain two degrees of mobility relative to the housing 1, the grip elements 7 are connected to the axis m1: 11, 1 radial grooves (2, fixed in the lid 2. At the lower free ends of the gripping elements 7, the input bevels 13 are worn. The carrying element 6 serves to connect the gripper to the Load-carrying device 14. FIG. 1 2 shows the product to be gripped 15 ( j; hole 16.

I When the carrier element 6 is fixed (the rod 4 is movable and controls the curtain element (the casing 7 becomes the link 1 of the drive unit. Its working movement for gripping the product 15 is directed downwards and is combined under the joint action (curbing force and own weight, but creates only preloading of the gripping elements 7 against the walls of the aperture. Further and complete compression of the gripping elements 7 is ensured with the subsequent: lifting of the grip due to their self locking: nivan from the perceived weight of the load.

When the working pressure is supplied to the upper cavity of the power cylinder, the body 1 s: the lid 2 is moved up to the specified position upwards (Fig. 1). At the same time, under the action of 4 t g 9 connected with a fixed rod, the gripping elements 7 upper ends with axles 11 are pressed into the inner grooves 12, and the lower free ends move towards each other, forming a wedge similar to the bevel 13. Spring 5. located between the fixed piston 3 and the cover 2 will be compressed.

- In the initial position of the lifting device 14, the grip is inserted into the opening 16 of the product 15. A wedge-shaped arrangement contributes to this technique.

gripping elements 7 and the presence of bevels on them 13. The insertion of gripping elements 7 is carried out so that the rods 9 immediately (Fig. 1) or taking into account the stroke of the ram (Fig. 2) are recessed into the hole zone 16. Then the drive is reversed, The overpressure in the upper cavity of the power cylinder is relieved, the spring 5 expands, moving down the body 10 with the lid 2. The gripping elements 7, interacting with the rods 9 pivotally supported on the fixed brush 4, disperse to the side against the wall of the hole 16 of the product 15. Pull up for padded elements 7 at this point will be determined by the action of the spring 5 and the weight of the movable gripping portions, mainly of the housing 1 and the cover 2.

A snug fit and guaranteed compression of the gripping elements 7 against the wall of the hole 16 is provided with a stock of the radial stroke of the axes 11 in the slots 12 of the cover 2 and a certain angle o (Fig. 2) between the rods 9 and the horizontal dead plane passing through the axes of the hinges 10 on stock 4.

Next, the device 14 is made, the lifting of the gripping element by the bearing element 6. At the same time, the gripping elements 7 pressed against the product 15 generate frictional forces from the load being held, which coincide in the direction of the drive and, due to the presence of angle θ, at the location generally sufficient to hold the load force of the gripping elements 7.

The release of the grip from the product is carried out simultaneously with bringing the grip to its original position.
