Polishing head, polishing device and polishing equipment
ActiveCN111451906AImprove grinding efficiencyImprove yieldGrinding wheel securing apparatusGrinding headsPolishingEngineering
The invention provides a polishing head comprising a polishing body and a connection piece, wherein the polishing body and the connection piece are detachably connected. The connection tightness degree between the connection piece and the polishing body is adjusted, so that the diameter of the polishing body is controlled. By adjusting the connection tightness degree between the connection piece and the polishing body, the diameter of the polishing body is controlled, and then detachable rapid installation of the connection piece and the polishing body is achieved. Meanwhile, a polishing belton the polishing body can be rapidly and conveniently replaced. The polishing head is driven by an external drive device to rotate to polish a workpiece, a polishing point of the polishing head achieves the same polishing effect on the whole polished plane of the workpiece, so that the polishing efficiency and yield of the polishing head are improved. The invention also provides a polishing deviceand polishing equipment.
