Cooling liquid refluxing system for milling machine

Abstract

The invention discloses a cooling liquid refluxing system for a milling machine, comprising a hidden refluxing groove in a worktable component, a relatively independent cavity in a control box component, an oil receiving pan which is on one side of a lifting platform component and used for collecting the cooling liquid, and a communicating sleeve for making filtered cooling liquid flow back to a lathe body component. A hidden cooling refluxing system for the milling machine is advantageous in eliminating a rubber pipe employed by a traditional lathe, and improving the appearance quality of the lathe. The technical scheme of the invention is featured by employing a hidden water drainage design, removing a structure such as the rubber pipe with the premise of satisfying the water drainage performance of the lathe, improving the appearance quality of the product to a large extent, employing multiplex oil filtration screens, a hidden refluxing groove design and a design of adding a cover plate on an exposed part, not only increasing the repeated utilization rate of the cooling liquid, but also decreasing leaking and splashing phenomena of the cooling liquid, and keeping a clean working environment.

Description

technical field [0001] The invention belongs to the technical field of metal cutting machine tools, and relates to the structure of a milling machine. More specifically, the invention relates to a cooling liquid return system of a milling machine. Background technique [0002] At present, in the common metal cutting machine tools in the prior art, most of the return system of the milling machine is to drill and tap the threaded holes at both ends of the back side of the workbench, and connect the rubber hose through the pipe joint; the coolant is discharged to the chassis through the rubber hose, Then through the hole provided on the chassis, the coolant flows into the coolant storage cavity of the chassis. [0003] Using the above method, if the connection between the pipe joint and the rubber hose is not firm, leakage may occur and the working environment will be polluted. At the same time, the backflow through the surface of the chassis will cause secondary pollution to t...

AI Technical Summary

Problems solved by technology

[0003] Using the above method, if the connection between the pipe joint and the rubber hose is not firm, leakage may occur and the working environment will be polluted. At the same time, the backflow through the surface of the chassis will cause secondary pollution to the coolant, and the coolant may overflow the chassis and pollute the working environment.

Moreover, in order to meet the working stroke of the milling machine, the length of the hose often needs to be very long, which affects the overall appearance of the machine tool
