Oil return tank for precise rolling body centralized oil supply system

The utility model relates to an oil return tank for a precise rolling body centralized oil supply system, which comprises a tank body with an opening at the top. A cylinder and a baffle are installed in the tank body, the baffle is located below the cylinder, the cylinder is vertical, the baffle is conical and is coaxial with the cylinder, and the tip of the baffle faces upwards and right faces a lower port of the cylinder; an oil inlet pipe penetrates through the side wall of the tank body and the side wall of the cylinder and extends into the cylinder, and an outlet of the oil inlet pipe faces upwards. The cylinder is designed to be matched with the oil inlet pipe, the oil product is buffered upwards and then downwards from the cylinder, and the conical baffle arranged below the cylinder is matched for further buffering, so that the strength of the oil product impacting the bottom of the tank body is effectively reduced, and oil sludge deposited at the bottom is prevented from being turned out. 本实用新型涉及一种精密滚
