Description

The utility model relates to the field of mechanical engineering, in particular to devices, and can be used as technological equipment for turning a large mass product in order to combine controlled patterns or rotation at a given angle when installing products, mainly on a hydraulic test bench, requiring a specific location of the product On him.

Known rotary support device, made in the form of a circle, with movable elements in the form of rollers mounted on its surface, containing symmetrical annular lower and upper thrust guides, while the upper one is located on the lower belt of the rotary platform, a drive for moving the rotary support device, ( Patent RU 2524739 C1, IPC E02F 9/12 priority of 03/28/2013, published on 08/10/2014).

However, the dimensions of the known device of complex construction will be significant when turning products of large mass.

The closest technical solution chosen as a prototype is a rotary table containing a base with a faceplate mounted on it in the form of a plate located on the support balls and provided with a working plane for placing the workpiece on it, a mechanism for fixing the angular position of the faceplate, (Patent RU 2299117 C1, IPC B23Q 16/02 priority of 01/26/2006, publ. 05/20/2007).

A disadvantage of the known device is that the design of the device provides only the fixation of the rotating parts of the faceplate and does not have a mechanism for turning the faceplate.

The technical problem of the inventive rotary device is the creation of a compact in overall dimensions, able to rotate a small mass product with small angles with the most simplified design of the rotation mechanism.

The technical result is achieved by the fact that the device is rotary, containing a base in the form of a plate with a rotary table mounted on it, located on the support balls with the possibility of placing the product on it, the table rotation mechanism, according to the utility model, the table rotation mechanism is made in the form of a finger with the possibility of installation it into the square holes of the plate, made at the same distance from the center of rotation of the table, and equipped with a threaded hole for installing a pushing screw resting on the rod, screwed into one of the nearest threaded holes made on the end surface of the rotary table.

The implementation of the mechanism of the angular movement of the rotary table in the form of a finger having a square surface that is installed in any square hole of the plate, made at the same distance from the center of rotation of the rotary table. The finger also has a threaded hole for installing a pushing screw into it for abutment in the rod. The rod is screwed to the threaded hole closest to the installed finger on the end surface of the turntable. The presence of structural elements is compact in size and allows you to rotate products of large mass at small (given) angles, while applying minimal effort.

The utility model is illustrated by drawings, where:

in FIG. 1 - shows a rotary device, General view;

in FIG. 2 - shows a rotary table mounted on a plate with movable elements (balls) located between them in an annular conical groove, the mechanism for the angular movement of the rotary table, top view.

When describing a rotary device, the following elements are used:

1 - stove

2 - rotary table

3 - balls

4 - annular conical groove

5 - screw

6 - nut

7 - limiters

8 - product

9 - square holes on the table

10 - square finger

11 - screw

12 - stock

13 - holes on the end surface of the table

The rotary device contains a base in the form of a plate 1, on which a rotary table 2 is mounted on supporting movable elements in the form of balls 3 (Fig. 1). Balls 3 are located with a gap in the annular conical groove 4 formed by combining the conical grooves on the plate 1 and table 2. (Fig. 2). The plate 1 and the rotary table 2 are interconnected by means of a screw 5 and nut 6, while ensuring free rotation of the rotary table 2 relative to the plate 1. On the working surface of the rotary table 2, limiters 7 are installed, which ensure that the product 8 is placed on it in the desired position. The position of the stops 7 depends on the dimensions of the base of the products 8. Square holes 9 are made on the plate 1 at the same distance from the center of rotation of the rotary table 2. For rotation of the product 8 there is a mechanism for angular movement of the rotary table 2 in the form of a finger 10 having a square section in which a threaded hole for installing the pushing screw 11. The screw 11 interacts with the rod 12 (pushes) screwed into one of the nearest threaded holes 13. The threaded holes 13 are made on the end surface of the rotary table 2.

The rotary device operates as follows.

On the surface of the rotary table 2 with the limiters 7 pre-set to the desired position (the position of the limiters depends on the size of the base of the tested products), install the product 8. The rotary table 2 is mounted on balls 3 movably with a gap in the annular conical groove 4 of the plate 1 and the rotary table 2 The rotary table 2 is attached to the plate 1 by means of a screw 5 and nut 6, while ensuring free rotation of the rotary table 2 relative to the plate 1. To rotate the product 8 by a given angle or to ensure the alignment of the patterns of the product 8 with technological equipment (presumably a hydraulic test bench) on which the rotary device with the product is located, install a finger 10 having a square cross-section in any square hole 9 of the plate 1. The rod 12 is twisted into the nearest (in the necessary direction of rotation of the product) hole 13 made at the end of the rotary table 2. Screw into the finger 10 screw 11 all the way with the rod 12. Then, applying spanner, turn the product 8 by the required value. To increase the rotation of the product 8, unscrew the screw 11 from the finger 10, and the rod 12 is rearranged in the hole 13 closest to the finger 10. If necessary, repeat the operation.

Thus, the proposed rotary device is small-sized, simple in design and rotates a large mass product, applying little effort.

Claims (1)
