The proposed machine for the continuous processing of parts contains mounted on a fixed frame using elastic suspensions 1 a working chamber 2 with a vibration exciter 3. Vibration exciter 3 using an elastic coupling 4 is connected to the engine 5. At one of the end. the walls of the working chamber in the zone of the highest pressure of the loading medium there is a chute 6. The transporting tray 7 with the separating grating 8 is mounted on the bed using flat springs 9. The drive of the transporting tray consists of a connecting rod 10 with two ball joints and a slider 11, which is located in a groove 12 of the working body. In the working body are the processing medium 13 and dividers 14.

The vibration machine operates as follows.

The working chamber 2 with the processing medium .13 and parts 14 are informed of oscillatory movements. Under the influence of vibration, the loading medium rises along the chute 6 and enters the separating grid 8 of the transporting tray 7. The transporting tray receives longitudinal vibrations from the working body using the slider 11 through the connecting rod 10. By changing the position of the slider 11 in the groove 12 of the working body, the amplitude of the longitudinal vibrations is changed. Under the influence of vibration, the processing medium is sifted through the openings of the separating grate and falls on the transporting tray, which transports it to the loading zone of the processed parts, and the processed parts move along the separating grate in the direction of the discharge zone. The drive of the transporting tray converts the oscillations of the working body in the vertical plane into the longitudinal pitch of the transporting tray in the horizontal plane due to the connecting rod with two ball joints. A diagram of the variation in the amplitude of vibrations of the transporter tray is shown in FIG. 4.Ugol between the axis of the connecting rod and the longitudinal axis of the PA ₍ 'bochego body (the angle () may ^vary, within 0 ~: ag 90® -β, where p> _______ e--OGSSO and ¹ g ~>

one. . The image refers to abrasive and hardening vibration treatments —and can be used in all mechanical engineering and instrument making industries. A machine is known for vibratory processing of parts by a granular abrasive-polishing medium, containing an elastic suspended linear linear working chamber with a vibration exciter and located along one from the side walls of the working chamber a tray for transporting the working medium mounted on inclined flat springs with the possibility of obtaining oscillatory movements from Nij working chamber, the working chamber is provided with means, ensures, both overflowing loaded onto tray carrier followed vozratom the working chamber}. A disadvantage of the known machine is the lack of conditions for ensuring the continuous processing of parts loaded into a pile. The purpose of the invention is to provide processing in continuous mode | of parts loaded into a pile. The goal is achieved by the fact that the inclined springs are fixed on: the base, and the transporting tray is supplied; The dividing grid is connected to the working chamber by means of a rocker mechanism, the slider of which is connected by ball joints with the lot and the connecting rod, while the connecting rod is mounted in a groove made on the side wall of the container with the possibility of changing its angular position relative to the longitudinal axis of the container.
