Description

Inclined bed body with lubricating oil return groove and oil collecting box

Technical Field

The invention relates to the technical field of numerical control machine tools, in particular to a slant lathe bed with a lubricating oil return chute and an oil collecting box.

Background

When the lathe is used, the saddle part and the tailstock installed on the guide rail all need to be lubricated to the workstation (install the turret subassembly on the workstation) that the guarantee is located on the saddle guide rail can remove about along the saddle guide rail on the saddle, removes the in-process, can provide lubricating oil for the saddle guide rail, reduces the workstation and removes the resistance with the saddle guide rail, thereby prolongs the life of workstation and saddle guide rail.

In the machining process, because an oil pump is required to continuously provide lubricating oil for the saddle guide rail, redundant lubricating oil can flow to the mounting surface of the guide rail along the saddle guide rail; for the sake of convenience to the recovery to lubricating oil, I department has developed an oblique lathe bed, and the slope is provided with guide rail installation face on the bed body, all is equipped with the bounding wall at the limit portion of guide rail installation face to make and form the oil gallery between bounding wall and the guide rail installation face, and the oil gallery that is located guide rail installation face low department sets up in the slope, is equipped with the oil pipe that returns that is located the oil gallery low department on the bounding wall, collects lubricating oil.

In the process of machining parts by a machine tool, flaky or filiform scrap iron and other residues are generated, and the residues can be mixed with lubricating oil to flow from the oil return groove to the oil return pipe, so that the recovered lubricating oil cannot be directly used.

Disclosure of Invention

The invention aims to provide a slant bed which can separate residues from lubricating oil so as to be directly used by the lubricating oil.

In order to achieve the purpose, the technical scheme of the invention provides the inclined bed body with the lubricating oil return groove and the oil collecting box, which comprises the oil collecting box, a partition plate, a separation mechanism, an oil supply mechanism and a vibration mechanism, wherein the oil collecting box is divided into a first cavity and a second cavity by the partition plate; the separating mechanism comprises a U-shaped groove and a separating cylinder, the U-shaped groove penetrates through the first cavity and the second cavity, the separating cylinder is rotatably arranged in the U-shaped groove, the oil return pipe is positioned above the separating cylinder, and a plurality of pores are formed in the side wall of one side of the axis of the separating cylinder; the oil supply mechanism and the oscillating mechanism are located in the second cavity, the oil supply mechanism can convey lubricating oil in the second cavity to the saddle guide rail, and the oil supply mechanism can drive the separating cylinder to rotate in the U-shaped groove in a reciprocating mode through the oscillating mechanism.
