Description

Technical Field

[0001] The utility model relates to a fine grinding device, in particular to a smooth fine grinding device for a sealing ring contact surface. Background Art

[0002] The sealing ring is a ring-shaped metal ring that is tightly pressed against the connecting parts to enhance the sealing between the connecting parts. For example, when connecting flanges, a sealing ring is required between the two flange connecting parts to enhance the sealing effect. Before using the sealing ring, all contact surfaces of the sealing ring must be hardened and polished.

[0003] The purpose of fine grinding of the contact surface is to make the surface of the sealing ring smooth and free of parting lines; remove surface flash and burrs; and reduce surface roughness, increase glossiness, and improve brightness, so as to enhance its sealing performance. Common fine grinding methods include flat grinding machines and double-sided grinding machines.

[0004] When using a flat grinder, the processing personnel place the sealing ring on the grinding disc, and then place a heavy object on the sealing ring to enhance the grinding effect; after grinding, the heavy object is removed and the sealing ring is removed. This repeated placement and removal of heavy objects increases the workload of the processing personnel and reduces production efficiency. Utility Model Content
