Lubricating oil pump oil-sucking pipe structure of numerically controlled machine tool

Abstract

The invention discloses a lubricating oil pump oil-sucking pipe structure of a numerically controlled machine tool. The lubricating oil pump oil-suction pipe structure structurally comprises an oil return pipe, a through opening, an eccentric sleeve, a pipe joint, a rotor and an oil sucking pipe. The inner end of the oil return pipe is provided with the rotor. The bottom end of the oil return pipeis connected with the pipe joint through the through opening. The outer ring of the pipe joint is fixedly provided with the eccentric sleeve. The eccentric sleeve is connected with the through opening through the pipe joint. The side end of the pipe joint is provided with the oil sucking pipe. The output end of the oil sucking pipe is fixedly connected with the eccentric sleeve. The oil sucking pipe is composed of a polygonal metal strip, a half-arc-shaped pipe segment, a circular pipe segment, a straight pipe segment and a U-shaped metal strip. The polygonal metal strip and the U-shaped metal strip are fixedly mounted and arranged on the left side and the right side of the oil sucking pipe correspondingly. The inner ends of both the polygonal metal strip and the U-shaped metal strip areprovided with filtering mesh belts correspondingly. According to the lubricating oil pump oil-sucking pipe structure of the numerically controlled machine tool, oil supplying by an oil pump is convenient and fast, the situation that air enters the oil pump is avoided, by filtering impurities in oil, cleaning is easy, and meanwhile, the working efficiency is improved.

Description

technical field [0001] The invention relates to an oil suction pipe structure of a lubricating oil pump of a numerically controlled machine tool, which belongs to the field of oil suction pipes. Background technique [0002] Oil pump is a light and compact pump, an oil pump with a housing made of aluminium-containing material and a movable molded part arranged in the housing, wherein the movable molded part At least partly made of a sinterable material comprising at least an austenitic iron-based alloy, and wherein the molding made of a sinterable material has a coefficient of thermal expansion of at least the housing 60% coefficient of thermal expansion. [0003] The existing published technology application number is: CN201220212575.6, an oil suction pipe assembly for a forklift, including an oil suction pipe joint, a flange and an oil suction pipe. The flange is connected; the oil suction pipe is pre-bent and arranged on the outside of the flange, one end is connected t...
