Description

(54) AUTO OPERATOR

one

The invention relates to mechanical engineering, in particular to auto operators intended for servicing technological equipment, in particular for forging machines.

An auto operator is known to control the process equipment, which contains a mechanical arm with a gripper, a drive and a device for feeding parts to the gripping position 1, made in the form of a cam, elastically connected with the gate 2.

The disadvantage of these auto operators is that they do not have wide technological capabilities.

The closest solution to the proposed is an auto-operator, which contains a mechanical arm with a gripper and a shaft, connected with a drive shaft, on which a steering mechanism cam is installed, kinematically connected through a safety device with the shaft of the arm, a drive with a tray and a gate, and device raising and lowering hands 3.

The disadvantage of an auto operator is that it has a rather complex design.

The purpose of the invention is the expansion of technological capabilities and the simplification of the structure.

This goal is achieved by the fact that the device for supplying parts is made in the form of a crank-and-rocker mechanism, the crank of which is fixed on the drive shaft, and the slide is connected to the gate of the drive, while the safety device is made in the form of levers hinged on the shaft, its axis and spring-loaded between

10 by itself, and one of such levers is connected with the cam of the turning mechanism, and the other with the shaft of the hand.

FIG. 1 shows a kinematic 5 auto operator scheme; in fig. 2 shows a version of the mechanism for supplying parts.

Claims (3)

An auto operator consists of an electric motor 1, a gearbox 2 with interchangeable gears for changing the work cycle, a drive shaft 3, a mechanical arm 4 with a shaft 5, 20 of the arm turning mechanism, a safety mechanism, a lifting and lowering arm mechanism, a feed mechanism for the gripping position and an accumulator tray 6 with a gate 7. The mechanism of rotation of the arm is made in the form of a cam 8, mounted on the drive shaft 3 and kinematically connected through a safety mechanism with the shaft 5 of the arm 4. The cam 8 interacts with the lever 9, freely installed bent on the axis 10 and connected through the spring 11 to the lever 12, which is also freely mounted on the axis 10. On the shoulder of the lever 12 is fixed a finger 13, the free end of which is located in the groove 14 of the fork lever 15 mounted on the shaft 5 and spring-loaded 16 hand-lowering side 4. Turning arm 4 is limited by stops 17 and 18. The mechanism for lifting and lowering arm 4 is made in the form of a slot cam 19 fixed on the drive shaft 3 and interacting with the double-arm lever 20, one shoulder of which is located in the annular groove 21 of the fork lever 15. The feed mechanism for the gripping position can be either in the form of a crank-cam mechanism, the crank 22 of which is attached to the drive shaft 3, and the link 23 is kinematically connected with the gate 7 of the accumulation tray 6 with parts 24, or in the form of a cam 25 mounted on the drive shaft 3 and elastically interacting with the gate 7. The operator operates as follows. Rotation from the electric motor 1 through the gearbox 2 is transmitted to the drive shaft 3. When the shaft 3 is rotated, the cam turns levers 9 and 12 around the axis 10. The lever 12 with the pin 13 interacts with the fork lever 15, turning the shaft 5 and the arm 4 until it stops 17. At the same time The force from turning the arm 4 does not exceed the force compressing the spring 11. During the rotation of the arm 4 to the stop 17, the crank 22 with the wings 23 moves the gate 7 to the final position, while providing the part 24 from the storage tray 6 to the gripping position. When turning the arm 4 and moving the part 24 to the grip position, the lever 20 with one shoulder rolls the cam 19 along a horizontal plane. As soon as arm 4 finishes the angular movement, the same arm of the lever 20 moves from the horizontal plane to the differential plane of cam 19, arm 4 makes vertical movement to part 24. After gripping part 24, arm 4 is raised and rotated until it stops 17, while spider moves to the starting position. Then the cycle is repeated. Claims of the invention: An auto operator containing a gripping arm with a shaft connected to a drive shaft on which a steering mechanism cam is mounted kinematically connected through a safety device to the shaft of the arm, a drive with a tray and a hook and a device for lifting, lowering the arm and feeding parts to a gripping position, characterized in that, in order to expand technological capabilities and simplify the design, the device for feeding parts is made in the form of a crank-and-rocker mechanism, the curvature of which is fixed flax on the drive shaft, and the link is connected with the gate of the drive, while the safety device is made in the form of levers that are pivotally mounted on a common axis and are spring-loaded among themselves, and one of these levers is connected to the turning mechanism cam, the other to the shaft .
