Secondly, it ensures the free passage of parts under the action of a vulture of gravity. The channel 55 feeds the parts into the hole 16 of the sleeve 6 from one direction, which eliminates the arching above the hole 16. The height of the channel 15 is chosen so as to ensure the simultaneous delivery of 2-10 parts. For a number of parts, the number of channels 15 in the sleeve 6 can be increased to 2–3, which allows increasing the supply of parts to the hole 16, but avoiding free circulation.

The channel 3 in the base 4 is made with a profile corresponding to the shape of the fuey part, and is intended for the free passage of the parts under the action of gravitational forces. In the housing 1, along the periphery of the base 4, there are located outlet channels of nozzles 7 made in threaded bushings 18 in the form of profiled channels. The number of them is determined by the required capacity and performance of the vibrating hopper.

The direction of the nozzles 17 is chosen in such a way that the flow of the working fluid when exiting from these nozzles interacts with the surface of the II bowl 5. The other end of the nozzles 17 is connected to a source of working medium. The nozzles 17 themselves can have a profile of a narrowing nozzle or Laval nozzles, which ensures the conversion of the potential energy of the working medium into the kinetic energy of the flow of the working medium with the highest efficiency and the flow, respectively, of transonic and supersonic speeds. The size of the gap 10 is selected from the conditions for ensuring the passage of the flow of the working medium flowing from the nozzles 17 and the required frequency of rotation of the bowl 5 relative to the base 4, which predetermines the productivity of the unloading of the parts and vibrobunker.

The angle o (inclination of the axis of the threaded sleeve 18 to the horizontal plane) determines the magnitude of the pressure force of the working medium flow to the bowl 5 upon impact, as well as the length of the path of interaction of the working medium flow with the surface II of the shell 5 due to friction (after impact). angle images (determines the magnitude of the pressure force and the friction vortex created by

overloading the part of 5 through channel 15 into the hole 16 of the sleeve 6, stapling, rotating to coincide with the hole 3 and lowering the part into this hole 3, that o6ecne4viBcieT orienting it along the angular coordinate. When the flow of the working medium flowing out of the nozzles 17 interacts with the medium in the gap 10, the medium is mixed with the working medium, captured by it

. and is emitted into the atmosphere, which causes the creation and maintenance of a vacuum in the gap 10. This forms an air cushion between the surface 13 of the oscillating tea 5 and the bottom surface 7 of the base 4 due to suction of the medium from channel 3 to the air gap 10, which features a sharp decrease friction between the base 4 and the bowl 5, which is significantly reduced due to the vibration of the bowl 5.

nozzles 17, has a radial, vertical JQ walls of the channel 19 provide possible and tangential components of velocity, which exert pressure on the bowl 5, creates the force of friction of the flow on the surface 11 of the bowl 5 and the torque applied to the bowl 5. The presence of the gap 10 and torque, causes the rotation of the bowl 5 relative to the base A and the oscillation of the bowl 5 in the central bore 2 about the vertical axis, as well as about two horizontal axes. The vibration of the bowl 5 is transmitted to parts, which drastically reduces the force of friction of parts along the bottom 14 of the bowl 5 and among themselves. Under the action of vibration and gravity sip, de-talted along an inclined bottom. 14 bowls 5 move to the center and through channel 15 fall into hole 16 of sleeve 6. Rotating and oscillating with sleeve 6 interacts with the parts, driven by the forces of friction foot rotation relative to the base 4. When the part coincides with channel 3, it is lowered into channel 3 by the action of vibration and gravity, which ensures the orientation of the part along the angular coordinate. As the oriented parts are removed from channel 3 from the bottom. for example, a slide gate feeder is implemented19 whose profile corresponds to the shape of an orientable part. Channel 19 provides free passage of parts by gravity. Lateral

A possible embodiment of the device, when the message nozzles 17 with the atmosphere is made on the inner side surface 8 of the central bore 2 of the housing 1. In this case, the threaded bushings 18 should be placed in the upper part of the side steiki 9, and the longitudinal axes of the nozzles 17 should be small (5–20 a) angle to the horizontal plane, directing the flow of the working medium from the nozzles 17 down. The main part of the interaction between the flow of the working medium and the bowl 5 is applied to the top of the bowl 5j, i.e. to the most distant station of the center of gravity of the surface of the bowl 5. This leads to an increase in the moment of oscillation relative to the horizontal axes, which causes an intensification of the swivels of the bowl 5 and a decrease in friction by parts, and also

A possible embodiment of the device, when the message nozzles 17 with the atmosphere is made at the bottom 7 of the central bore 2 of the housing I. In this case, the threaded bushings 18 are placed so that the longitudinal axes of the nozzles 17 are directed at an angle to the bottom of the bowl 5 and are offset relative to the vertical axis of the housing I. This ensures the twisting of the working medium flow, lengthens the flow path of the working medium, which causes an increase in the force of the tray of the working medium flow on the surface of the bowl 5. The device works as described.

A possible embodiment of the device, when the bowl 5 is supported on the housing 1 by means of balls 20, is | placed in the annular groove 21, made in housing 1, thereby significantly reducing the friction forces of the bowl 5 through the housing 1, and also reduces the radius of application of the friction force, which leads to a reduction in friction losses and an increase in the use efficiency. energy of the working environment. The device works as described.

An embodiment of the device is possible when the oscillator nozzles 17 are complete. In the form of an annular nozzle 22 connected to a source of working medium through a channel 23, the longitudinal axis of which is displaced relative to the vertical axis of the housing 1. Such an embodiment of the nozzle 22 and channel 23 ensures the flow of the working medium and accelerating it to near-sonic or supersonic speeds when performing the nozzle 22, respectively, tapering or in the form of a combination of tapering and expanding nozzles (Laval nozzle). {2 koltsevv cost sharing reduces bone trudoem its manufacturing and allows to increase the power developed by oscillator that is required dp devices intended for the orientation of krupnogabaritnyh- ime- constituent parts and significant weight loaded parts. The device works as described.

It is possible to use the device when through holes 24 are made in housing 1, connecting the cavity of gap 10 between housing I and bowl 5 with the atmosphere. As a result

This supply of potential energy, generated by the interaction of the flow of the working medium flowing from the nozzles 17 and 22, with the medium in the gap 10 between the housing 1 and the bowl 5 in the form of a vacuum, is used to create a secondary air flow of the atmosphere flowing through the holes 24, a gap of 10 and further into the atmosphere. The secondary, atmospheric air stream interacts with the surface of the bowl 5 in the same way as the primary one and creates additional forces in the bowl 5 and the moment of rotation, thereby increasing the efficiency of using the energy of the working medium. The device operates as described, except that when the device is connected to a working medium source, the flow of the working medium flowing from the nozzles 17 or 22 creates a secondary stream of atmospheric air flowing through the holes 24 and the gap 10 into the atmosphere.

A possible embodiment of the device is when the side wall 9 of the housing I is fixed on the base 25 of the housing 1 for movement relative to the base 23, such fixing of the wall 9 is provided by an annular stop 26 fixed by means of a bolt 27 On the base 25. B. In this case the wall 9 has a flange 28 , a circular ring stop 26, such that there is a gap 29 for the Horizontal movement and a gap 30 for the vertical movement. The device works similarly described with the exception that when the device is connected to a working medium source, the flow of the working medium flowing out of u, con 17 or H2, such also interacts with the side wall 9, driving it in rotation and oscillation. In this case, the side wall 9 interacts with the bowl 3, exerting a pulsed effect on the bowl 3, leading to an expansion of the range of frequencies excited by the chat. This causes a decrease in the path between the parts loaded in the bowl 3 and the bottom t4 of the bowl 3, which It facilitates the movement of parts into the internal cavity of the sleeve 6.
