Abstract
The utility model discloses a finish machining tool for an inner bore of a fixing sleeve of a cooling water pump of a diesel engine. The tool comprises a bottom plate fixedly arranged on a cylindrical support on the bottom plate; a circular notch A is arranged at the axis of the support; a workpiece is placed at the top of the support when the tool is used; the circular bump of the workpiece extends into the circular notch A; a barrel cover is placed above the workpiece; a pressure rod passes through a circular through hole formed in the axis of the barrel cover; and the lower end of the pressure rod is connected with a hole expanding ball above the inner bore of the workpiece. When the inner bore of the fixing sleeve of the cooling water pump of the diesel engine is subjected to finish machining, after the workpiece is fixed by the tool, the pressure rod is pressed, so that the hole expanding ball penetrates through the inner bore of the workpiece. From the above process, when the inner bore of the fixing sleeve of the cooling water pump of the diesel engine is subjected to finish machining, the machining precision of the workpiece is ensured, and the defect rate of products is reduced.

The further improvement project of the utility model is, described depression bar upper end is fixed with pressing plate.
The utility model further improvement project is, the equal diameters of described manhole internal diameter and depression bar all is slightly less than the diameter of the endoporus of workpiece.
The utility model further improvement project is that the material of described reaming ball is high strength alloy steel.
The utility model further improvement project is that the slightly larger in diameter of described reaming ball is in the diameter of bore of workpiece.
The utility model further improvement project is, the Lower Half of described bearing one side is provided with the material taking hole that is connected with circular notch A, the width of described material taking hole and highly all greater than the diameter of reaming ball.
The utility model further improvement project is, the bottom surface coaxial line of casing is provided with circular notch B, and the internal diameter of described circular notch B equals the round bump diameter of workpiece, and the degree of depth of circular notch B is more than or equal to height and the reaming radius of a ball sum of round bump.
The beneficial effects of the utility model are:
When carrying out the fine finishining of cooling water pump of diesel engine fixed cover endoporus with the utility model, the endoporus of workpiece is by after lathe fine finishining, workpiece is placed on the bearing top, and projection is stretched in circular notch A; Then the reaming ball is placed on the endoporus upper end, and coordinates and place casing; The depression bar lower end is passed manhole and is contacted with the reaming ball; Then press down by punch press or the hammering way pressing plate with the depression bar upper end, drive depression bar the reaming ball is passed endoporus from top to bottom; Afterwards, the material taking hole set by bearing takes out the reaming ball, and takes off successively depression bar, casing and workpiece; Repeat above step, carry out the finishing of internal diameter of next workpiece from said process as can be known, carry out the fine finishining of diesel pump fixed cover endoporus with the utility model, guaranteed the machining accuracy of workpiece, reduced the inferior rate of product.
