The grinding hole after the heat treatment of the cylindrical-cone double gear is the key process that affects the accuracy of the gear. The tooling shown in the figure can effectively ensure the accuracy of the gear after grinding. The tool is positioned outside the circle A and the end face B, and is fixed on the transition plate of the machine tool spindle. The positioning of the workpiece is as follows: the bevel tooth end is positioned with a small amount of grease on the pitch circle, and is pressed in the position of the clamp 2 On the hole and the end face, the large end is positioned on the pitch circle of the workpiece by the section cylinder 4, and the small taper elastic expansion sleeve 7 is positioned on the specific cone surface of the clamp, and the sleeve is clamped to clamp the workpiece pitch circle. The small taper sleeve has high positioning precision and good self-locking property, and the cylinder is fixed and fixed by the cage 5, and is convenient to use. The specific positioning end face, inner hole and tapered surface of the clip are required to have high precision, and can be clamped and grounded on the machine tool once, and the nut 3 acts as a loosening effect. After the workpiece is processed, a special tool is used to pass through the side window of the nut, and the sleeve is loosened. The workpiece can be removed by removing the section cylinder, which is simple and quick, and can effectively ensure the accuracy of the gear after the hole is ground.
