AI Technical Summary

⚠Technical Problem

In the existing technology, the lubrication of the slider and slide rail of the ball screw relies on manual application of lubricating oil, which is inefficient and has an unsatisfactory lubrication effect. It is difficult to effectively enter between the slider and slide rail, which affects the transmission accuracy and service life.

⚗Method used

Design a self-lubricating structure including a slider, a flow guide component, an oil supply component, and an air supply component. The oil supply component supplies lubricating oil to the flow guide component to achieve automatic lubrication and heat dissipation between the slider and the slide rail. At the same time, the air supply component cleans debris and impurities from the inner wall of the slide rail.

🎯Benefits of technology

It achieves automatic lubrication of the slider and slide rail, reduces sliding resistance, prevents jamming, extends service life, and removes frictional heat through lubricating oil to prevent overheating.

Abstract

This invention provides a self-lubricating structure for machine tools, belonging to the technical field of machine tool accessories. It includes a slide rail body, a slider, a flow guiding component, an oil supply component, and an air supply component. The slider is slidably disposed inside the slide rail body. The flow guiding component is disposed on the side wall of the slider, and the oil supply component is disposed inside the slide rail body. When the slider slides along the interior of the slide rail body, the oil supply component supplies lubricating oil to the flow guiding component, allowing the lubricating oil to flow from within the flow guiding component. Compared to existing technologies, this invention automatically supplies lubricating oil to the position between the slider and the slide rail body when the slider slides along the slide rail body, thereby achieving automatic lubrication of the slider. Furthermore, the supply of lubricating oil also provides heat dissipation for the slider and the slide rail body, preventing excessive frictional heat between them from affecting their service life.
