AI Technical Summary

Technical Problem

Existing integrated drilling and polishing equipment lacks a limiting mechanism at the end face of the workpiece when drilling long workpieces, which leads to instability in the drilling process and easy accumulation of drilling debris, affecting subsequent use.

Method used

An integrated drilling and polishing device was designed, comprising a turntable, chuck, limiting components, a processing mechanism, and auxiliary components. The rotating mechanism and limiting components stabilize the drill rod, while the auxiliary components spray drilling fluid, ensuring the stability and efficiency of drilling and polishing.

Benefits of technology

It improves the stability of the drilling process, reduces chip accumulation, and enhances drilling and polishing results, making it suitable for machining drill rods of different sizes.

Abstract

This invention relates to the field of machine tool processing technology, specifically disclosing an integrated drilling and polishing equipment and method for producing drill rods for coal mine drilling rigs. The equipment includes a turntable and a mounting hole, with the central axis of the mounting hole coinciding with the central axis of the chuck, allowing the bottom of the first drill rod to extend along the inner wall of the mounting hole to the bottom of the machine platform. A pressing mechanism is provided at the top of the machine platform. This invention uses a first processing mechanism to drill from the bottom of the first drill rod. Under the influence of gravity, the vibration of the first drill rod during drilling, and the rotation of the second drill rod, the debris generated during drilling falls downwards, reducing the amount of debris accumulating in the hole and facilitating subsequent continuous drilling. This is more suitable for the long drill rods used in coal mine drilling rigs. Furthermore, by setting up identical first and second processing mechanisms, drilling and polishing are facilitated, effectively improving the drilling and polishing results.
