The invention relates to a reamer floating device for deep hole machining, and a floating reamer. Special double-head square threads are used for axial positioning, and high-precision holes and shafts are cooperated for radial positioning to connect a reamer and a reamer rod; the positioning is convenient and reliable, and the replacement and maintenance are facilitated; through cooperation of the spherical surface, the non-concentricity of a main shaft and a deep hole in the machining process is easy to compensate through the reamer in the 360-degree range; the angle of the reamer floats slightly, thereby facilitating feeding and tool setting; and the axial hole design facilitates realization of internal cooling, lubrication and washing way of cuttings, and the machining precision and the surface quality of the hole are improved. The reamer floating device is particularly suitable for deep hole finish machining of common holes. Through the reamer with the floating device, deep hole finish machining can be achieved on a common cutting machine tool; and manual machining of bench workers can be replaced with deep hole cleaning and roundness correction after heat treatment, and the labor intensity is reduced. Under the condition that the hole machining precision is met, compared with honing machining, the hole finish machining efficiency is improved by 80%, the process economy is better, and the reamer floating device is suitable for single and batch production.
Description
technical field [0001] The invention relates to a reamer floating device for deep hole processing and a floating reamer. Background technique [0002] At present, on ordinary cutting machine tools, deep holes that cannot be processed conveniently and reasonably with standard hole processing tools are often used to finish the holes by reaming and stringer grinding. Grinding and pulling hinges can be used for the through hole; when the hole is blind and the bottom of the hole requires high precision, since one end of the bottom needs to be vacated during the grinding, reaming is often used for finishing. In actual processing, there is a coaxiality error between the spindle of the machine tool and the hole to be reamed, the reamer cannot be perfectly inserted into the hole and is guaranteed not to be subjected to any radial force, and the tool rod is slender, poor in rigidity and low in strength, and the machined There is a roundness error in the hole, and it is difficult to d...
