Closed type sliding following oil receiving device applied to oil return of hydrostatic guideway

Abstract

The invention discloses a closed type sliding following oil receiving device applied to oil return of a hydrostatic guideway. The closed type sliding following oil receiving device is applied to high-quality unresisted recovery of hydraulic oil of the hydrostatic guideway, and comprises a dustproof sealing ring gland, a gland fixing screw, a dustproof sealing ring, an oil conveying pipe, a closely-pitched locking nut, a compound gasket, a sealing compound gasket, an oil receiving transitional screw, an oil receiving box, an upper cover of an oil receiving tank, the oil receiving tank and an oil receiving tank fixing screw, wherein the oil receiving box is fixed and is communicated with an oil outlet of a sliding table of the hydrostatic guideway through the oil receiving transitional screw; a threaded end of the oil conveying pipe is fixedly arranged on the oil receiving box through the closely-pitched locking nut, is lower than the oil outlet of the sliding table of the hydrostatic guideway and is parallel to an axis of the hydrostatic guideway; through the sealing of the sealing compound gasket, an oil outlet end of the oil conveying pipe is always positioned inside the oil receiving tank within the stroke; and the oil receiving tank is fixedly arranged on a machine tool body by the oil receiving tank fixing screw and is sealed through the upper cover of the oil receiving tank and the dustproof sealing ring, so leak-free unresisted high-cleanliness recovery of hydraulic oil is realized.

Description

technical field [0001] The invention relates to a closed sliding follow oil receiving device applied to oil return of a hydrostatic guide rail, and is particularly suitable for recovering high-quality hydraulic oil from a hydrostatic guide rail without resistance. Background technique [0002] The oil return of the hydraulic oil of the hydrostatic guide rail is generally transmitted back to the oil tank through a hose or directly flows back to the oil tank. Hydrostatic guideway oil discharge requires hydraulic oil to flow into the oil return device under its own gravity. During the flow process, there is no resistance interference. When the hydraulic oil is transmitted through the hose during the movement of the hydrostatic guideway, it will produce The bending hinders the return flow of hydraulic oil, resulting in the failure of the static pressure guide rail to release pressure, forming a pressure difference, deriving a load, causing the loss of guide rail motion accuracy,...

Problems solved by technology

Hydrostatic guideway oil discharge requires hydraulic oil to flow into the oil return device under its own gravity. During the flow process, there is no resistance interference. When the hydraulic oil is transmitted through the hose during the movement of the hydrostatic guideway, it will produce The bending hinders the return flow of hydraulic oil, resulting in the failure of the static pressure guide rail to release pressure, forming a pressure difference, deriving a load, causing the loss of guide rail motion accuracy, and failing to achieve the use effect; if the return oil of the static pressure guide rail flows out of the oil return tank in an open state In the middle, the cleanliness of the oil return tank cannot be well guaranteed. The flying chips or coolant during the cutting process of the machine tool will splash into the open oil circuit. In this way, it is necessary to add filtering and oil-water separation devices in the oil tank, which greatly increases the cost.
