Description

Technical Field

[0002] Drill pipe is a steel pipe with a thread at the tail end, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the well. The purpose of the drill pipe is to transport drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The drill pipe must be able to withstand huge internal and external pressure, twisting, bending and vibration. In the process of oil and gas extraction and refining, the drill pipe can be used many times. Drill pipe is divided into three categories: square drill pipe, drill pipe and weighted drill pipe.

[0003] In most of the existing drill rod production processes, the drill rod main shaft is produced by injection molding, and its surface glossiness is low, so it needs to be polished to prevent damage during use. Most of the existing drill rod polishing methods are manual polishing, which is inefficient and has inconsistent polishing accuracy. During the machine polishing process, it cannot adapt well to the fixation, rotation and movement of drill rods of different lengths and diameters, which increases the time for drill rod polishing. It is necessary to design a drill rod polishing device to solve the above-mentioned problems. Utility Model Content
