SU1362886A1 - Device for converting reciprocating motion to intermittent rotary motion - Google Patents

Abstract

The invention relates to mechanical engineering, in particular to devices for converting movements, and can be used, for example, to move workpieces under a press from one position to another. The purpose of the invention is to expand the operational capabilities of a plow and higher smoothness of the crank of the driven link. In the initial position, the gripper is disengaged from the pinhole 11 and is in the extreme right position, rotated under the action of the spring 16. When the pusher 4 is left to move, the iodine interleaves along the body guide with a spring 7. At the same time, the groove 10 of the gripping device 7 interacts with the pinhole 11 of the disk 12. The roller, moving across the surface of the profiled groove, smoothly rotates the gripper 7 and the disk 12 by one step, equal to the central angle between the adjacent pinions. 4 il. Vida S (L.

Description

The invention relates to mechanical engineering, in particular to devices for converting movements, and can be dismantled, for example, for moving the sharpening of the press from one position to another.

The purpose of the invention is to enhance operational capabilities by improving the smoothness of the rotation of the slave link.

FIG. 1 shows a device for converting a reciprocating motion into a discontinuous-shape, general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 is a view of B in FIG. 3

The device for converting the reciprocating motion into a discontinuous rotational movement comprises a housing 1, to which 1) the actuator 2 is rigidly attached. For example, in the form of a pneumohydraulic cylinder with a rod 3. A leading link of the device in the form of a pusher 4 is attached to the rod 3, which on axis 5 is mounted roller 6 controlling gripper 7. The latter is made in the form of a plate mounted on axis 8 in bracket 9. On one side of gripper 7, groove 10 is made to interact with pin 11 of disk 12, and on the other side groove 13 interacting with p face 6 and which provides gripping rotation 7. Moving the operating position Manu- Dietz bracket 9 by a spring 14 to the guide 15 of the body 1, and returns to the starting position - by means of the pusher 4.

The gripper 7 is spring-loaded to the bracket 9 by a spring 16. Setting the gripper 7 to its initial position is made

by means of the stop 17, which adjusts the tension of the spring 16. To ensure the engagement of the groove 10 of the gripper 7 with the choke 11, the size a between the outer surface of the roller 6 and the surface 18 in contact with it of the profiled groove 13 must be greater than or equal to the size between the outer surface of the axle 11 and the contact surface of the groove 10 of the grip 7.

A device for converting a reciprocating motion into a discontinuous rotational motion operates as follows.

Air (oil) is supplied to the piston cavity of the pneumo-hydraulic actuator 2, the rod 3 of which moves the pusher 4 to the initial position. When I OM pusher L, rast with

Curtain spring 14 moves bracket 9 along guides 15 to the right to its original position. The bracket 9, moving to the right, does not hold the gripper 7 behind it until it comes out of engagement with the pin 11. After that, the clamp 7 under the action of the spring 16 is rotated to its original position by the groove 10 and is set against the next pinhole 11. Adjusting the clamp setting by the 7 groove 10, directly opposite the coil 11, is carried out with the aid of an emphasis 17.

Air (oil) is supplied to the rod cavity of the pneumohydroirror drive 2, the rod 3 of which, moving to the working position, does not follow the pusher 4 with the roller 6. When moving the pusher 4, the arm 9 moves behind it under the action of the spring 14. a distance passes inside the gripper 7. During this time, the groove 10 grips the next pinhole 11. After that, the roller 6, continuing to move along the surface 18 of the profiled groove 13 of the gripper 7, rotates the last B working position (one step or central angle between p house standing the camber 11). Then the cycle repeats.
