Abstract

The invention relates to mechanical engineering, namely to assembly devices. The aim of the invention is to increase reliability. For this, the free end surface of the process sleeve 2 is made toroidal. On the sleeve 2 is fixed flange 6 with the installation element under the part. The part may also be located in the bore of the sleeve 2. In the housing 1 there are tangential channels in which the sleeves 4 with nozzles are installed. When the working medium is supplied through the nozzles, the sleeve 2 begins to rotate with part 11. The part is held by the process flow. When docking the part 11 with the counterpart, the assembly takes place. The flange 6 can be fixed with a gap on the sleeve 2. In this case, both end surfaces of the sleeve 2 are toroidal. It is possible to replenish the actuating mechanism, in which the inner surface of the housing 1 is equidistant on the outer surface of the sleeve 2 along the outer contour. 2 hp f-ly, 13 ill. with $ O)

The invention relates to mechanical engineering, in particular to assembling devices and auxiliary means of industrial robots.

The purpose of the invention is to increase reliability.

The actuator includes a housing 1 and a process sleeve 2, which is installed in the cylindrical cavity 3 with a gap. In the housing 1 there are tangential channels in which threaded bushings 4 with nozzles 5 are installed.

Depending on the embodiment of the actuator, the nozzles 5 may be directed at different angles to the longitudinal axis of the sleeve 2 to create an upward or downward flow of the working medium. The process sleeve may be integral with the flange 6. The surface of the groove 7 passes into the toroidal surface 8 of the free end of the sleeve 2. The flange 6 can be installed with a gap in the sleeve 2. The gap can be formed either by channels 9 (see Fig.4) or ribs 10 (see Fig.5). Groove 7 serves to locate part I 1. The installation element on the flange 6 can be made in the form of a head, or in the form of a socket 12 for part 13 (see Fig.6).

For better circulation of the working medium, both end surfaces of sleeve 2 can be made toroidal (see Fig. 8), and the toroidal surface can be formed by channels 14. In flange 6 it is possible to place several slots 1 2 under the collected parts, while flange can be d through (see Fig. 6) or continuous (see Fig. 8). The installation of the process sleeve 2 in the housing 1 may also be different. It is possible to perform when the inside surface of the housing 1 is equidistant to the outer surface of the sleeve 2 along the outer contour (see Fig. P). It is possible to install the sleeve 2 on the balls 15, and the groove in the sleeve under the part may have any shape (see Fig. 12).

The actuator operates as follows.

The pressurized working medium flows out of the nozzles 5, having a dynamic effect on the sleeve 2. The sleeve 2 begins to rotate. The working medium, which bends the surface of the sleeve 2, rushes into the groove 7, where the part 11 is located, while the flow of the working medium keeps the part 11 in the groove.

Next, the actuator is transferred to the assembly position and assembled.

 For convenience of placing parts 13, slots 12 are used that are made in flange 6.
