End socket edge cutting device and method
PendingCN114309872AImprove the efficiency of edge cuttingRealize the fine-tuning functionWelding/cutting auxillary devicesAuxillary welding devicesCircular discEngineering
The invention discloses an end socket edge cutting device and method. The end socket edge cutting device comprises an end socket supporting disc, an alignment fine adjustment assembly, a plurality of air cylinders, a transmission system and a cutting gun. A seal head can be placed on the seal head supporting disc, the alignment fine adjustment assembly can assist the seal head in conducting preliminary horizontal alignment through the dead weight, the multiple air cylinders are evenly distributed along a circular track, the circular track is coaxial with the seal head supporting disc, and each air cylinder can stretch out and draw back in the radial direction of the circular track. The extending end of a piston rod of each air cylinder can abut against the straight edge of the end socket to enable the end socket to move towards the center of the end socket supporting disc so that the end socket can be placed right, the transmission system can drive the end socket supporting disc to rotate, and meanwhile the cutting gun can cut the edge of the end socket. The end socket can be aligned for multiple times, and the edge cutting quality and efficiency are improved.
