Improved lathe oil distribution valve assembly

The utility model discloses an improved lathe oil distribution valve assembly, which comprises a valve body and an oil cylinder, wherein a valve core and a piston are arranged in the valve body, the front part and the back part of the valve body are respectively provided with an end cover and a back cover, the tail end of the valve core is provided with a tail end bearing, and the head end Y-shaped oil seal part of the valve core is provided with a head end bearing. Because the head end of the valve core is provided with the head end bearing, two ends of the valve core are respectively supported by the tail end bearing and the head end bearing, the positioning is stable, the rotation stress is uniform, the abrasion between the valve core and the valve body is reduced, and the service life is prolonged. When the replacement is needed, only the bearings are replaced, the valve body and the valve core do not need to be replaced.
