Description

The invention relates to automation and mechanization of production processes and can be used in various fields of technology, in particular for feeding parts into the working area of a press.

The purpose of the invention is to increase reliability by simplifying the design of the gripping device, which is achieved by performing the stop fixed on the housing of the fixed part 21, the slider 4 stops before it reaches the stop 3, and the rod 8 continues to move, will act with a cam 14 on the roller 13. At the same time, the double shoulders lever 11 with the sponge 15 is rotated, ensuring at the expense of the spherical hinge 16 a uniform pressing of the part 21 against the clamping sponge 18 and maintaining the basis of the part 21 along the shoulder 20.

When a part is clamped without fixing on a pile cylinder, the rod cavity of which, on a tick 20, slider 4 stops is fitted with a spring, and one of the jaws has a needle 3, after which the part is clamped 15

25

The mobile device is not movable and the sensor controlling the presence of a part in the gripper is hinged on it.

The drawing shows a gripping device.

The gripping device consists of a power cylinder 1, on whose case 2 a stop 3 is fixed, which is designed to interact with a slider 4 fixed on a rod 5, which is rigidly connected to a piston 6 placed in an opening 7 of a rod 8 of a power cylinder 1 connected to a piston 9 spring-loaded spring 10. On the slider 4 a double-shouldered lever 11 is pivotally mounted, spring-loaded by a spring 12, on one shoulder of which is fixed a roller 13, interacting with a cam 14, and on the other - a clamping jaw 15, fitted with a spherical hinge 16, pressed from two a lever and an elastic element 17. A clamping sponge 18 with a hole 19 and a thrust collar 20 securing the part 21 is fixed on the slider. In the clamping sponge 15 with a spherical hinge 16 a nozzle 22 coaxially with a hole 23 connected to the source 24 of compressed air is placed coaxially Equipped with sensor 25 for compressed air consumption.

The device works as follows.

In the initial position, the piston 9 with the rod 8 is pressed by the spring 10 to the extreme right position. The piston 6 is in the left position, interacting with the wall of the hole 7 of the rod 8. The clamping jaw 15 is in the upper position pressed by the spring 12. After supplying compressed air to the power cylinder, the piston 9 with the rod 8 moves to the left side, while the piston 6 is compressed by compressed air to the wall of the hole 7 of the rod 8. As soon as the clamping sponge 18 with its collar 20 rests on

Similarly.

In this position, a gap is formed between the piston 6 and the wall of the opening 7. With the presence of the part 21, the air from the nozzle 22 is not consumed, and the air flow sensor 25 authorizes the next operation. If there is no part at the loading position, air from the nozzle 22 through the opening 19 enters the atmosphere, the sensor 25 detects the presence of air flow and gives a signal that the part is missing. When the part is unloaded, the compressed air supply to the power cylinder is stopped, the spring 10 returns the piston 9 to its initial position, the rod 8 first moves, and the rod 5 with the piston 6 remains in place due to the air overpressure in the cylinder cavity acting on the piston 6. This is done by first turning the lever 11 with the spring 12, releasing the part 21, and after the wall of the opening 7 of the rod 8 acts on the piston 6, the rod 5 moves together with the slider 4, freeing the working area.

Claims (1)

Invention Formula 35 o A gripping device containing a ram cylinder with a hollow rod, kinematically associated with clamping jaws and an actuator mounted inside a hollow rod, made in the form of a piston with a rod, on which a slider with jaws mounted on it is fixed, while ensuring the possibility of interaction with the slider drive an emphasis is made, characterized in that, in order to increase reliability, the emphasis is made fixed on the body of the POWER-cylinder, in the rod cavity of which a compression spring is installed, and one of the lips is made under izhnoy and pivotally mounted thereon a sensor monitoring the presence of items in captivity. 45 the fixed part 21, the slider 4 stops, does not reach the stop 3, and the rod 8 continues to move, the copier 14 acts on the roller 13. In this case, the double-arm lever 11 with the sponge 15 rotates, ensuring that the part 21 is evenly pressed to the clamping jaw by means of the spherical hinge 16 18 and save the basing of the detail 21 on the flange 20. When clamping the part without fixing on the drill five Similarly. In this position, a gap is formed between the piston 6 and the wall of the opening 7. With the presence of the part 21, the air from the nozzle 22 is not consumed, and the air flow sensor 25 authorizes the next operation. If there is no part at the loading position, air from the nozzle 22 through the opening 19 enters the atmosphere, the sensor 25 detects the presence of air flow and gives a signal about the absence of the part. When the part is unloaded, the compressed air supply to the power cylinder is stopped, the spring 10 returns the piston 9 to its initial position, the rod 8 first moves, and the rod 5 with the piston 6 remains in place due to the air overpressure in the cylinder cavity acting on the piston 6. This is done by first turning the lever 11 with the spring 12, releasing the part 21, and after the wall of the opening 7 of the rod 8 acts on the piston 6, the rod 5 moves together with the slider 4, freeing the working area. Invention Formula 5 o A gripping device containing a ram cylinder with a hollow rod, kinematically connected with clamping jaws and an actuator mounted inside the hollow rod, made in the form of a piston with a rod, on which a slider with jaws mounted on it is attached, while allowing the interaction with the slider drive an emphasis is made, characterized in that, in order to increase reliability, the emphasis is made fixed on the body of the FORCE-cylinder, in the rod cavity of which a compression spring is installed, and one of the lips is made Izhnaya and on it is pivotally mounted sensor controlling the presence of parts in the grip. five
