(54) ROTARY CLEARING DEVICE

one

Image bridging refers to the machine tool industry. and can be used in machine tools containing rotary devices.

A rotary dividing device is known, which contains a dividing disc with tangs that interact with a shaped groove located at one end of the lever, the second end of which is hingedly connected to the hydraulic cylinder rod, and the rotary support 1.

This rotary dividing device has significant dimensions and due to its design is not sufficiently high reliability.

The purpose of the invention is to reduce the size of the device and increase the reliability of its operation.

The goal is achieved in that the device lever is provided with an abutment and a Radial through hole is made in the rotary support, the rotatable support is mounted to the axially separating disk, and the lever is placed in the aforementioned rotary support hole with the possibility of moving along the axis of the aperture and interacting through the stop with swivel support.

FIG. 1 shows a rotary dividing device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - time cut AA in FIG. 1 (first intermediate position); in fig. 4 shows section A-A in FIG. 1 (second intermediate position); in fig. 5 is a section A-A in FIG. 1 (third intermediate position); in fig. 6 -

10 view B in FIG. one; in fig. 7 is a section bb of FIG. 2

The rotary dividing device contains a base 1, a rotary table 2 connected to the dividing disk 3, with the pinholes 4 mounted on it, the power

 a cylinder 5, a lever 6 on which an emphasis 7 is made and which is mounted in a pivot bearing 8 with a protrusion 9 and a hole 10 made perpendicular to its axis and in which the specified lever is located, the rotation limiter 11 is limited, the torsion spring 12, the stop 13. Figured a groove with walls 14-16 and a section 17 above, made on one of the arms of the lever 7, the other end of which is hingedly connected to the rod 18 of the cylinder 5. The stop 13 is mounted on the base 1. The spring 12 is fixed at one end to the rotary support 8, and the other rests against the stop 13. If the axis of the hinged fastening is cylin pa 5 and the axis of the rotary support 8 connect forward, the swivel axis of the rod 6 with the lever 7 will be located on the side of this straight (FIG. 2). The rotary dividing device works as follows. When the working fluid is supplied to the corresponding cavity of the power cylinder 5, its rod 18 mixes the lever 6 in the hole 10 until the meeting of the stop 7 with the swivel support 8. At the same time (FIG. 3), the bobbin 4 first comes out of the section, turning the separating disk 3 and connected to there is a rotary table 2. After meeting the stop 7 with the rotary support 8 (FIG. 4), the lever 6 rotates together with the rotary support 8 and the bobbin 4, abutted against the wall 14 of the shaped groove. In this case, the protrusion 9 moves away from the rotation limiter 11, the spring-on 12, abutted against the abutment 13, is twisted. Together with the bobbin 4, the pivoting disc 3 and the table 2 are rotated. When the cylinder 5 (Fig. 5) moves backward, the lever disengages from the bobbin 4, rotates together with the pivot 8 until the projection 9 meets the pivot stop 11. to the rum, the protrusion 9 is again pressed by the spring 12, the wall 15 of the shaped groove meets and slightly rotates the subsequent pinhole 4 together with the pitch disc 3 and the turntable 2. After fixing the position of the pivot bearing 8 due to the meeting of the protrusion 9 with the rotation stop 11, the lever 6 sha2.

Claims (1)

, / in hole 10, the stop 7 moves away from the pivot bearing 8, the bobbin 4 meets with the inclination wall 16, along which it slides into section 17 of the height (Fig. 2) where it is fixed, and hence the fixation of the rotary table 2 in the new position If the stops on the pitch disc are set uniformly, then the division is uniform. If, on the other hand, the angular spacing between adjacent stops is different, non-uniform division occurs, corresponding to the specified angular pitch. This embodiment of the device makes it possible to create a fairly compact design with a sufficiently high reliability of its work. The invention includes a rotary dividing device containing a dividing disc with a pair of axles interacting with a shaped groove located at one end of the lever, the second end of which is pivotally connected to the hydraulic cylinder rod, and a swivel bearing, characterized in that in order to reduce the size of the device and increase reliability its work, the lever is provided with a stop, and a through radial hole is made in the pivot bearing, the pivoting bearing is mounted coaxially to the separating disk, and the lever is placed in the said hole and a rotary support with the possibility of moving along the axis of the hole and interacting by means of an abutment with a rotary support.
