AI Technical Summary

Technical Problem

Traditional CNC machine tool guideways suffer from low lubrication efficiency, uneven lubrication, and difficulty in cleaning, leading to increased wear and decreased lubricant performance, which affects the machine tool's accuracy and lifespan.

Method used

A CNC machine tool guide rail with a self-lubricating structure was designed. Through the cooperation of the sliding device and the lubrication device, the flow of lubricating oil is controlled by the tapered tube to form a uniform oil film. Impurities are cleaned simultaneously by the cleaning cotton, which reduces wear and keeps the guide rail clean.

Benefits of technology

It achieves precise control and uniform distribution of lubricating oil, reduces wear, extends the service life of guide rails, and improves the working performance and overall lifespan of machine tools.

Abstract

The utility model discloses a numerical control machine tool guide rail with self -lubricating structure, the utility model relates to mechanical engineering technical field, the utility model, including: workstation, the inner wall sliding connection of workstation has sliding device, the outer wall fixed connection of sliding device has lubricating device, through setting the cooperation of sliding device and lubricating device, oil tank imports lubricating oil, and its bottom end connected conical pipe output end is conical, can accurate control lubricating oil flow, forms even and effective oil film on the surface of guide rail, reduces abrasion, and the discharge pipe of symmetric connection of the bottom end of sliding slot can discharge extra lubricating oil and impurity in time, and the gasket of inner wall contacts with the outer wall of runner, further optimizes the sliding process, and reduces the jam phenomenon, and the cleaning cotton can clean the guide rail when sliding on the workstation simultaneously. Cleaning cotton can adjust position through screw rod pin, and the runner is covered, can effectively remove the chip, dust and other impurities on the surface of guide rail, prevent its purpose from entering the sliding component.
