The invention discloses a device for
polishing an inner hole weld root of a high-temperature
alloy furnace tube. The device for
polishing the inner hole weld root of the high-temperature
alloy furnace tube comprises a furnace tube rotating
power transmission device, a furnace tube supporting device, a
grinding device and a
grinding supporting device. The furnace tube rotating
power transmission device, the furnace tube supporting device and the
grinding supporting device are installed in sequence, the high-temperature
alloy furnace tube is installed on the furnace tube supporting device, one end of the high-temperature alloy furnace tube is connected with the furnace tube rotating
power transmission device, and the grinding device is installed on the grinding supporting device. According to the device for
polishing the inner hole weld root of the high-temperature alloy furnace tube,
automatic control is achieved, only manual monitoring is needed in the weld root polishing working process, labor intensity is reduced, and working efficiency is improved; by arranging a limiting shaft and a
magnetic switch, limitation and automatic reversing are achieved, the polishing position and distance of the furnace tube weld root can be determined accurately, the shortcoming that polishing is not performed on the designated position or the polishing distance is too long in the artificial polishing is overcome, and accordingly polishing quality of the furnace tube weld root is effectively guaranteed.
