The invention relates to a combined deep hole drilling rod mechanism and deep hole drilling method. The drill rod is provided with an auxiliary drill rod at the position corresponding to the chip removal groove. The auxiliary drill rod includes an inner hole grinding mechanism, a chip removal mechanism and an auxiliary drill rod. Driving mechanism; the inner hole grinding mechanism includes a hob and a helical scraper arranged on the auxiliary drill rod, the chip removal mechanism includes a continuous spring leaf with a spiral structure, and the auxiliary drill rod driving mechanism includes a coaxially fixed on the rotating shaft The friction ring and a transmission mechanism fixed on the frame for driving the rotation of the friction ring; the deep hole drilling method includes successively a pre-drilling step, a charging step, a deep hole drilling step, a deep hole inner wall grinding step, a deburring step, Chip removal step and differential speed chip removal step; deep hole drilling is realized through the drill pipe, the inner wall of the deep hole is ground by the hob, the inner hole is deburred by the spiral scraper, and the chip removal step is performed by the spring sheet; one-time completion The reprocessing and chip removal of the inner wall of the deep hole improves the efficiency.
Description
technical field [0001] The invention relates to a drill rod for deep hole drilling and a method, in particular to a combined deep hole drill rod mechanism and a deep hole drilling method. Background technique [0002] In the process of deep hole drilling, chip discharge has always been a problem. Excessive cutting accumulation will lead to poor hole processing quality, and in severe cases, it will cause drilling jamming and breakage. At the same time, if the debris is not discharged in time, it will also cause secondary grinding to the inner hole, making the straightness of hole processing and the roughness and gloss of the processed surface worse. The general solution is to improve the process parameters and increase the oil pressure, but the actual effect is not good. Especially for some difficult-to-machine materials, the processing quality is poor, and the drilling efficiency is seriously affected. Contents of the invention [0003] The technical problem to be solved...
