The invention provides a grinding wheel motorized spindle, which can solve the technical problem that the traditional grinding wheel motorized spindle is not suitable for high speed machining. The grinding wheel motorized spindle includes grinding wheel tooling and spindle. The grinding wheel tooling includes grinding wheel seat and grinding wheel chuck. The motorized spindle includes the spindle. The right part of the grinding wheel seat is provided with assembly holes. The left end of the spindle is provided with assembly bumps. The features of the assembly holes are: the assembly holes include conical holes, step surfaces and cylindrical holes arranged in turn from left to right, and the assembly cams include conical holes, step surfaces and cylindrical holes arranged in turn from left to right. The right opening diameter of the conical hole is smaller than the right root diameter of the conical convex block. The cylindrical convex block is inserted into the cylindrical hole. The grinding wheel seat is provided with bolts distributed around the axis in the area of the bench surface of the base body. The bolts are threaded through the grinding wheel seat and connected with the main shaft. The conical convex block connects the conical hole. When the side wall is opened, the step surface of the seat body and the step surface of the shaft body fit together.

砂轮电主轴
本专利技术涉及电主轴领域,具体涉及砂轮电主轴。
技术介绍
传统砂轮电主轴包括砂轮工装和电主轴,砂轮工装包括砂轮座和砂轮夹盘,电主轴包括主轴、套筒、轴承组和电机,砂轮座的右侧部位设有装配孔,主轴的左侧端部设有装配凸块,装配孔、装配凸块均为截头圆锥结构,砂轮座与主轴端部通过装配孔、装配凸块定位配合并且通过装配孔、装配凸块的内、外锥面之间的摩擦力传递扭矩,主轴端部螺纹连接有锁紧螺母,锁紧螺母对砂轮夹盘进行轴向限位。该传统砂轮电主轴在转动情况下,砂轮座具有向径外侧脱离的趋势,导致装配孔和装配凸块之间的摩擦力减小,而在电主轴高速转动的情况下,内、外锥面之间的摩擦力将不足以将砂轮座与主轴端部有效固定,存在安全隐患,故该传统砂轮电主轴并不适用于高转速加工的情况。
