Description

Technical Field

[0001] The utility model relates to the technical field of grinding processing equipment, in particular to an upper mounting mechanism of a spherical grinding machine. Background Art

[0002] A spherical grinder is a device used to grind and polish the surface of a workpiece with a spherical surface. This design processes two workpieces with spherical surfaces, where workpiece one has a convex spherical surface and workpiece two has a concave spherical surface, where the inner diameter of the concave spherical surface is the same as the outer diameter of the convex spherical surface, but the height of the concave spherical surface is smaller than the height of the convex spherical surface. In the past, the two workpieces were usually processed separately by two separate grinding devices, resulting in low production efficiency and high cost. Currently, a spherical grinder is designed to grind the two workpieces against each other. The two workpieces are installed separately by the upper mounting mechanism and the lower mounting mechanism for grinding. However, due to the different grinding areas of the two workpieces, if the upper mounting mechanism adopts the conventional vertical mounting method of the workpiece, the two workpieces are set opposite to each other. Grinding in this state cannot fully grind workpiece one, so it needs to be improved. Utility Model Content
