Description

Technical Field

[0001] This utility model relates to the field of flange grinding technology, and in particular to a device for grinding the end face of a connecting flange. Background Technology

[0002] A flange connection is a detachable joint in which two pipes, fittings or equipment are first fixed to a flange, then a flange gasket is placed between the two flanges, and finally the two flanges are tightened with bolts to make them tightly connected. It can realize the connection between stationary pipes and rotating or reciprocating equipment.

[0003] During the casting or forging process, flange surfaces may develop defects such as burrs and oxide scale. Grinding can remove these defects, ensuring sealing and structural strength during connection. The flange end face needs to contact the gasket to achieve a seal. Grinding can ensure that the end face is flat and smooth, improve the sealing effect, and prevent media leakage.

[0004] During the grinding process of flanges, because flanges are designed with a ring structure, when grinding the flange end face, the grinding wheel only acts on the outer periphery, resulting in high wear and tear on the grinding wheel, increased usage costs, and the entire grinding wheel cannot fully and effectively achieve the grinding effect. Grinding only the outer periphery will cause continuous high temperature and poor grinding effect. Therefore, a flange end face grinding device is proposed. Utility Model Content

[0025] In use: After casting, the flange body 2 requires end face grinding. The flange body 2 to be ground is placed on two arc-shaped placement blocks 9. The spacing adjustment component, with two lead screw sliders 7 moving closer or further apart, adjusts the position of the arc-shaped placement blocks 9, allowing for the placement of flange bodies 2 of different diameters. Rotation adjustment ensures stable clamping of the placed flange body 2, preventing slippage during grinding. During grinding, the rotary motor 3 on the rotating component is activated, causing the placed flange body 2 to rotate, thus enabling grinding of the flange body 2. During the rotary grinding process, the displacement drive component, under the action of rotational eccentricity, can drive the U-shaped drive rod 17 to move back and forth, thereby driving the grinding disc 15 to move back and forth.
