High-precision burr removal tool for engine crankshaft

The invention relates to the technical field of mechanical tool and discloses a high-precision burr removal tool for an engine crankshaft. The high-precision burr removal tool comprises a handle, wherein a pair of polishing heads is symmetrically arranged at one end of the handle; a bearing is rotationally mounted at the end, close to the polishing heads, of the handle; a central axis of the bearing is perpendicular to a plane of the handle. The tool is simple in structure, easy to manufacture and convenient to operate, can effectively solve the problems of incomplete burr removal, low work efficiency, high possibility of excircle scratch of a crankshaft journal and the like, effectively improves working efficiency at the same time, avoids reworking, saves working time and lowers machining cost. 本发明涉及机械工具技术领域，公开了种用于发动机曲轴的高精度毛刺去除工具，包括把手，把手端对称设置有对打磨头，把手近打磨头端转动安装有轴承，轴承的中轴线与把手平面垂直。其结构简单，易于制造，操作方便，能有效的解决毛刺去除不完全、工作效率低、易划伤曲轴轴颈外圆等问题，同时有效的提高了工作效率，避免了返工，节约了工作时间，降低加工成本。
