Description of the invention

The subject of the invention is a indexing table for discrete positioning of rotary devices, applicable for angular positioning of machine elements or workpieces.

There are known devices for stepless angular division based on a system of gears, differentials or planetary gears, and the positioned element is held in place by the frictional force generated by pressing one or more surfaces.

Discrete partitioning methods in rotary devices are also known. In these devices, the predetermined angular positions are obtained by form-fitting connections, e.g. discs with a system of holes, splines and notches, as well as cylindrical or face meshing. These connections allow for greater repeatability of settings, however, due to the limited number of angular positions, it is not possible to achieve high resolutions in these instruments.

The indexing table disc uses the frictional force generated by the pressure applied to one or more surfaces. The clamp can be divided according to the way force is exerted. A hydraulic clamp is used, less often a mechanical, pneumatic, electromechanical or electromagnetic clamp. The type and location of the clamp securing the table disc depends on the design and construction of the table. Current brakes on turntables and indexing tables use the force of the springs against the caliper, while the force generated by the brake actuator is used to release the brake.

The essence of the invention is a indexing table consisting of a disk, a spindle and a body, in which the disk with a spindle mounted through the inner roller sleeve in the guide sleeve is connected to the upper ring, which is connected with front gears through a spring-supported intermediate ring with the lower ring, and a bistable clamp the magnetic one is connected on one side to the body and on the other side to the spindle.

Thanks to the solution according to the invention, the following technical and operational effects were obtained:

- increasing the accuracy of table positioning by maintaining a constant clamping force of the front meshing,

- reduction of energy consumption thanks to the use of permanent magnets to hold the position,

- reducing the overall dimensions of the indexing device.

The invention, in an exemplary embodiment, has been shown in section in the drawing.

The table consists of a disc 1 with an upper ring 2. The disc 1 is connected to a spindle 11, which is seated by the inner roller 3 in the guide sleeve 5. The intermediate ring 4 supported by the spring 9 is seated by the outer roller 7 on the guide sleeve 5. The guide sleeve 5 is permanently fixed in the body 10. The body 10 has a lower ring 6 and a bistable magnetic clamp 8, which is connected to the spindle 11. The upper ring 2, the intermediate ring 4 and the lower ring 6 are connected to each other by front meshing. .

Toothed front: the upper ring 2, the intermediate ring 4 and the lower ring 6 in the intermediate ring 4, by changing the mutual angular position, they enable the angular position of the disc 1 to be set. During spreading and sliding, the upper ring 2 is guided together with the disk 1 and the spindle 11 through the inner roller 3 in the guide sleeve 5. The intermediate ring 4 is guided through the outer roller 7 on the guide sleeve 5 and its movement is forced by the spring 9. Rotary movement of the upper ring 2 together with the disk 1 and the spindle 11 is enabled by the inner roller sleeve 3, and the intermediate ring 4 is enabled by the outer roller sleeve 7. The angular positions of the rings 2 and 4 are changed by drives not shown in the drawing. After setting certain angular positions by the control system not shown in the drawing, the upper rings 2 and the intermediate ring 4 are clamped by a bistable magnetic clamp 8.
