STROKE ADJUSTMENT DEVICE Russian patent published in 2022 - IPC B24B23/04 B24B41/04 B24B47/10 

FIELD: material processing.

SUBSTANCE: group of inventions relates to material processing by cutting; it can be used in adjusted orbital devices, in particular in polishing and grinding machines, and massagers. A stroke adjustment device contains a case with a central axis and a wall enclosing a cavity. At least one balancing device is located in the cavity, made with the possibility of movement in the specified cavity, and a mounting assembly, which contains a mechanism of working body attachment. The stroke adjuster connects at least one balancing device to the mounting assembly. The stroke adjuster provides the possibility of movement of the balancing device and the mounting assembly relatively to each other under a condition of gradual adjustment of a distance between the balancing device and the mounting assembly, providing gradual adjustment of a radius of the stroke of the mechanism of working body attachment relatively to the central axis of the case.

EFFECT: gradual adjustment of the stroke of an orbital eccentric machine, taking into account user’s needs.
