Abstract
The utility model discloses a rotary positioning device. The rotary positioning device comprises a rotary foundation which is provided with two positioning grooves; the two positioning grooves are in axial symmetry; the rotary foundation is provided with a deep groove bearing which can be clamped into the positioning groove which is opposite to the deep groove bearing; and the deep groove bearing is in clearance fit with the positioning groove and is provided with a drive mechanism. According to the rotary positioning device, the rotary foundation is provided with the two positioning grooves which are in axial symmetry and is provided with the deep groove bearing which can be clamped into the positioning groove which is opposite to the deep groove bearing; automatic guide and circular arc transition are adopted, so that the directly stressed rotary positioning is avoided; and the structural mode of combining linear bearings, guide rods and the deep groove bearing, and rotating a workpiece positioning seat is adopted, and the bearing is rotated, so that the collision between materials, which is generated when the materials are not positioned accurately, can be avoided due to the roundness, the wear degree is reduced, and the positioning accuracy rate and manufacturing cost are reduced.
