The upper plate can be moved up and down by the lifting cylinder, and the upper shaft can be driven to rotate by the upper motor. The inner surface of the center through hole of three different specifications of flanges can be polished by the upper grinding wheel, the middle grinding wheel and the lower grinding wheel.

[0013] 2. The clamping connection between the upper clamping block and the side groove, and the threaded connection between the positioning nut and the shaft body not only ensure the stability of the connection between the upper grinding wheel, the middle grinding wheel, the lower grinding wheel and the upper rotating shaft, but also enable the staff to replace the required specifications of the grinding wheel as needed, thereby further meeting the grinding needs of the inner surface of the center through hole of more flanges of different specifications;

[0014] 3. The staff only needs to start the lower cylinder to make the end of the grinding rod fit with the side surface of the flange, start the first lower motor, and slide the first slide plate in one direction along the slide rail, so that the side surface of the flange can be polished by the end of the grinding rod. The sliding connection between the first slide plate and the slide rail and the stable maintenance of the grinding rod position by the lower cylinder effectively ensure the grinding quality of the side surface of the flange.

[0015] 4. The staff only needs to start the second lower motor to collect the waste generated when grinding the side surface of the flange through the rotation and sliding of the roller brush, so as to keep the space between the slide rail and the flange clean. In addition, the through groove allows the waste generated by the upper grinding wheel, the middle grinding wheel or the lower grinding wheel when grinding the inner surface of the central through hole of the flange to fall directly under the lower plate for subsequent cleaning, thereby effectively ensuring the overall cleanliness of the equipment during operation;

[0016] 5. The connection between the lower clamping block and the clamping groove, and the penetration of the connecting bolts through the output shaft of the second lower motor and the lower clamping block, not only ensure the working stability of the lower rotating shaft and the roller brush, but also enable the staff to replace the lower rotating shaft and roller brush of appropriate specifications according to the flange size, so that the length of the roller brush is consistent with the distance between the flange side surface and the slide rail, thereby further meeting the grinding requirements of flanges of different specifications;

[0017] 6. The overall structure of this equipment is simple, so the cost is low. At the same time, it can meet the grinding processing requirements of flanges of different specifications, taking into account the grinding quality and cleanliness, and effectively meet the relevant needs of small businesses.

After the grinding work is completed, the first lower motor 18 and the second lower motor 22 are turned off, the output end of the lower cylinder 20 is reset, and the flange 9 is removed to complete a working cycle.
