DEVICE FOR SURFACE MACHINING OF PARTS Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: device has tumbling drums positioned in row along one axis of rotation. Moving reception grating is located under every drum. Grating cell size is smaller than size of part being machined but larger than size of machining medium particles. Stationary tray provided with bottom slide is arranged under grating. Discharging car with box capable of moving in horizontal direction in parallel to drum axis is also part of device. Discharging car is coupled with accumulation bunker through separating slide. Accumulating bunker is installed along axis of number of drums and is capable of vertical movement with positions of charging and filling of distribution tank. The latter is positioned above level of drums in horizontal guides and is capable of moving along drums and bunker. EFFECT: more efficient machining of part surface. 4 cl, 4 dwg
