The invention relates to machine building and instrument making and can be used for finishing and hardening the processing of small mass parts.

The aim of the invention is the expansion of technological capabilities by providing adjustment of the amplitude of oscillations.

FIG. 1 shows a diagram of a device for vibratory processing, a longitudinal section; in fig. 2 - the same, top view.

The device consists of a container 1 of a ring-shaped form fixed on the base 2, a vibrator 3, an oscillation control mechanism 4 and a driving electric motor 5. The container of the device is made in the form of two walls of a cylindrical form 6 and 7 connected by an elastic bottom 8. The outer wall of the container 6 is rigid mounted on base 2. and internally - on the movable element of the vibration adjustment mechanism - nut 9. The nut 9 moves vertically when the adjusting screw 10 rotates, which is installed with bearings on the vibrato shaft 11 and 3.

The vibrator is made in the form of a group of rollers 12, rolling around the bottom 8 of the container with the rotating shaft 11. Movement from the electric motor 5 is transmitted to the shaft 11 with the aid of a wedge-lowering transmission 13.

V.

The device works as follows.

The working medium 14 is loaded into the container. When the electric motor 5 is turned on, the rollers 12 rotate, rolling around the elastic bottom of the container. As a result of the running-in of the bottom of the container, the mass of the load 14 is reported to have a pulsating oscillatory motion, which causes a general circulation of the load. The process of processing. When the screw 10 is rotated, the nut 9 of the vibration amplitude adjustment mechanism 4 vertically moves the inner wall 7 of the container 1, which raises or lowers the elastic bottom 8. The amount of pressing-in of the rollers 12 into the bottom 8 changes, the amplitude of the loading oscillations changes accordingly. The implementation of the mechanism for adjusting the amplitude of oscillations in the form of a screw pair, which is not mechanically coupled by a C-vibrator, allows adjustment during the operation of the vibrator, i.e., without turning off the vibrator. The ability to control the amplitude of oscillations allows you to set the most productive mode or to ensure the required law (optimal) of the amplitude of oscillations during processing, which allows the device to increase its performance in several cases several times or to ensure acceptable intensity for non-rigid parts, which rasschir et. capabilities of the device and allows it to be used for different stiffness of parts. In addition, the possibility of sticking flat children is eliminated. This is provided by the characteristic of transmitting oscillatory motion from the bottom of the device to the mass of the load.
