AI Technical Summary

Technical Problem

Existing reamer drill bit mechanisms have a fixed diameter and cannot dynamically adjust the reaming diameter, requiring frequent drill bit replacements, which is inefficient and increases costs.

Method used

The drill bit structure with adjustable hole diameter is adopted. Through the telescopic cooperation of the sleeve and connecting rod, combined with the hinge seat and limiting structure, the hole diameter can be infinitely adjusted. It is equipped with multiple sets of cutting blocks to distribute the load and reduce stress concentration at single points.

Benefits of technology

It enables flexible adjustment of the hole diameter, adapting to different hole diameter requirements without changing the drill bit, improving work efficiency, reducing wear rate, reducing the probability of drill jamming, and ensuring the stability and reliability of hole reaming.

Abstract

The reamer comprises an exploration supporting plate, a horizontal display instrument and a support, the bottom of the support is fixedly connected with a telescopic rod, the bottom end of the telescopic rod is fixedly provided with a motor, the bottom of the motor is fixedly provided with a rotating rod, and the bottom of the rotating rod is fixedly connected with a drill bit structure capable of adjusting the reaming diameter. The drill bit structure comprises a sleeve, a connecting rod is arranged at the bottom end of the sleeve, a drill bit is fixedly connected to the bottom end of the connecting rod, a plurality of equidistant reaming assemblies are arranged outside the sleeve and the connecting rod, and the sleeve and the connecting rod complete fixation of the telescopic length and the reaming diameter through a limiting structure. According to the drill bit structure, the sleeve is matched with the connecting rod in a telescopic mode, the expansion assembly is connected with the cutting arm and the connecting arm through the hinge base, the cutting arm is provided with the multiple sets of equidistant cutting blocks to form a layered cutting structure, different telescopic lengths are fixed in combination with limiting structures (bolts and nuts), and stepless adjustment of the reaming diameter is achieved; different hole diameter requirements can be met without replacing the drill bit.
