Abstract
The invention discloses a tool and a method for finish machining of an inner hole of a fixing sleeve of a diesel cooling water pump. The tool comprises a bottom plate and a cylindrical support fixed on the bottom plate. The support is axially provided with a circular groove A. A workpiece is placed at the top of the support when the tool is used. A circular protrusion of the workpiece extends into the circular groove A. A barrel sleeve is disposed above the workpiece. A pressure bar penetrates an axial round through hole of the barrel sleeve. The lower end of the pressure bar is connected with a broaching sphere on the inner upper portion of an inner hole of the workpiece. After the workpiece is fixed by the tool when the tool is used for finish machining of the inner hole of the fixing sleeve of the diesel cooling water pump, the broaching sphere is allowed to penetrate through the inner hole of the workpiece by pushing down the pressure bar. By the use of the tool, machining precision of the workpiece is guaranteed and product rejection rate is lowered.
