Abstract
The invention belongs to a mechanical processing field, and particularly relates to a coarse and fine composite boring device of a coaxial sleeve part. The coarse and fine composite boring device consists of a boring cutter and a boring cutter bar and is characterized in that the left end of the boring cutter bar is connected with a main shaft of a lathe, the right side of the boring cutter bar penetrates through a hole of the coaxial sleeve part to be machined to be connected with a tailstock of the lathe through a bearing, an inner ring of the bearing is in transition fit with the boring cutter bar, an outer ring of the bearing is in interference fit with the tailstock, the boring cutter bar is provided with a coarse boring cutter and a fine boring cutter, the fine boring cutter is arranged at left side of the coarse boring cutter, the coaxial sleeve part is positioned by taking a supporting plate of the lathe as the benchmark and is tightly compressed through a compressing device. The coarse and fine composite boring device disclosed by the invention is simple in structure and convenient to operate, production efficiency is high and precision of the part is easy to control.
