Tool for rapidly assembling and disassembling small parts of cylindrical grinding machine

The utility model relates to the technical field of aviation grinding machining, in particular to a tool for a cylindrical grinding machine to quickly assemble and disassemble small parts. The tool for the cylindrical grinding machine to quickly assemble and disassemble the small parts is in the shape of a cylinder (1), a line-shaped deep groove (2) is formed in the axis direction of the cylinder (1) with the circle center of the cylinder (1) as the center, two parallel planes (4) are symmetrically arranged at the end, same as the line-shaped deep groove (2), of the cylinder (1) with the end face of the cylinder (1) as the starting point, and the two parallel planes (4) are perpendicular to the line-shaped deep groove (2); stepped holes (3) are formed in the two parallel planes (4) and penetrate through the two parallel planes (4); the external grinding device is simple in structure, safe, efficient and capable of being popularized to external grinding procedures of other small-size parts. 本实用新型涉及航空磨削加工技术领域，尤
