Automatic rotary grinding equipment

The invention relates to the technical field of grinding equipment, in particular to automatic rotating type grinding equipment which comprises two rotating discs and a cylindrical grinding cutter, and the two rotating discs are coplanar in the vertical direction; the two eccentric shafts which are in the eccentric state and do circular motion are adopted to drive the workpiece body to do arc-shaped movement, the workpiece body can be made to do arc-shaped movement while the workpiece body is limited and guided, and the workpiece body can do translational motion conveniently; the workpiece body actively gets close to the cylindrical grinding cutter, and the arc surface of the inner wall of the workpiece body is ground through the cylindrical grinding cutter in the rotating state, so that an automatic grinding machining mode is achieved, and the workpiece body can directly move in an arc shape through the mode; compared with a traditional mode that a workpiece body can move in an arc shape through comprehensiv
