Abstract

The invention relates to a dividing device that provides rotation in equal angular steps. The purpose of the invention is to simplify the design and increase reliability by combining the drives for moving the lock and turning the disk. On the shaft 3 of the device, there is a pivoting lever 5 freely rotating on it and a rotatable lever 5 fixed by a spring-loaded stopper 4 with a guide sleeve 6 for the reciprocating moving tooth 7. The latch 8 is connected to the drive 9 and pivotally connected 10 to 7 and a double-shouldered lever 1, the second arm of which is hingedly connected to the pusher 12, the finger 13 of which is placed in the groove 14 of the lever 5. When pressure is applied to the pneumatic cylinder of the actuator 9, the clamp 8 is pulled out of the cavity of the disk 2. Simultaneously under the action of the lever 11, The opposite direction of the pusher 12 and the lever 5. Together with the rotation of the lever 5, due to the interaction of the tooth 7 with the disk 2, coming after the release of the latch 8, the disk 2 also rotates. When the drive 9 returns, the tooth 7 leaves the interaction with the disk 2, and the latch 8 engages with it. In this case, through the lever 11, the pusher 12 moves in the opposite direction and rotates the lever 5 to the initial position. 1 il. g

The invention relates to mechanical engineering, in particular to dividing devices that provide rotation in equal angular steps.

The purpose of the invention is to simplify the design and increase the reliability of operation by combining the disk rotation drives and. moving the lock.

The drawing shows a diagram of the device.

The device includes a toothed pivoting disc 2 mounted in the housing 1, having the possibility of free rotation on the shaft 3 and a pivoting lever 5 fixed by a spring-loaded stopper 4, equipped with a guide sleeve 6 along which the tooth 7 moves back and forth. The latch 8 is connected to the curtain pneumatic cylinder 9 of a disk rotational drive 2 and pivotally connected 10 with a tooth 7 and a double-arm lever 11, the second arm of which is hingedly mounted on the pusher 12, the finger 13 of the latter is installed in the groove 14 of the rotary lever 5 and has The possibility of free movement. In the housing 1 has an adjustable stop 15.

The device works as follows.

In the initial position, the latch 8 under the action of the pneumatic cylinder 9 fixes the toothed separating disk 2. When pressure is applied to the cavity of the pneumatic cylinder 9, the latch 8 is pulled out of the cavity

of the separating disk 2, and the tooth 7 is inserted into the depression of the separating disk 2 by the action of the pull rod 10. At the same time, under the action of the double-arm lever 11, the upward pusher 12 moves, which with the help of a finger 13, which slides in the groove 14 of the pivoting lever 5, rotates the latter . Together with the pivoting lever 5, the separating disk 2 rotates. The maximum stroke of the displacement drive rod, which determines the required angle of rotation, is limited by the adjustable stop 15.

During the return stroke of the pneumatic cylinder 9, the new position of the separating disk 2 is fixed by the lock 8 and the tooth 7 is withdrawn from the bottom of the separating disk 2. At the same time, the push rod 12 returns, which returns the lever 5 to the initial position.
