The invention relates to machine tools and can be used for inter-item movement of the product.

A rotary-dividing table is known, which contains a base, a faceplate with uniformly spaced dividing plates, a locking device and a turn actuator associated with the faceplate through a C1.L coupling.

The disadvantage of this table is the possibility of a loose fit of the elements of the fixing device to the separating pin of the faceplate, h) reduces the reliability of operation.

The purpose of the invention is to increase the reliability of work.

This goal is achieved by the fact that in a rotary-dividing table, containing a base, in which a bearing is installed on the bearings with uniformly spaced circumferential plates, interacting with the locking device and turning actuator connected to the faceplate through the coupling, the fixed device is made dogs and stops, located on the base, and the coupling is installed coaxially to the faceplate and made friction, with the pivoting fingers, faceplate faces installed with the possibility of interaction ; focusing through the doggie.

In addition, the locking device is equipped with a lever mounted on the half-coupling connected to the drive with the possibility of interacting with the dog ....

FIG. 1 shows a schematic rotary-dividing table, common. view; in fig. 2: - section aa in figure 1

The shaft 1, which is rigidly connected to the face plate 2, on which the friction lining 3 of the coupling and the divider fingers 4 is fixed, is mounted on the base 5 with the help of Bearings b and is capable of axial movement. The weight of the faceplate 2 and the shaft 1 is perceived by the second coupling half 7 connected to the gear wheel 8, the lever 9, and the friction lining 10, the coupling half 7 is mounted in the base 5 on the bearings 11. On the base 5, the power cylinder 12 with the rod joint 13 located in engagement with the gear wheel 8, as well as the fixing device with the axis 14 of the pawl 15, loaded with a spring 16. On the base there are stops 17 and 18.

The device works as follows.

When moving the rod rack 13 down (Fig. 2), the half-coupling 7 together with the faceplate 2 rotates counterclockwise until the lever 9 interacts with the stop 18. The angular movement of the faceplate 2 is equal to the sum of the interposition angle and the additional movement necessary to rotate the dog 15 around the axis 14 AGAINST clockwise under the action of the dividing finger 4 to the position - in which the dividing finger 4 overtakes the dog 15 and the latter returns to the position shown in the drawing. When the stem assembly 13 is extended, the half-coupling 7 rotates clockwise. The faceplate 2 rotates with the clutch by an additional angle until the engagement of the dividing finger 4 with the dog 15. The further rotation of the clutch 7 is accompanied by relative slippage of the faceplate 2 and the half coupling 7, the slippage continues until the lever 9 interacts with the dividing finger 4 and the stop 17 through the dog 15.

The proposed pivoting-dividing table allows one to move and fix the faceplate using a single drive, which greatly simplifies the design and increases the reliability of operation. AR (
