The invention belongs to the technical field of steel plate
grinding, and particularly relates to a large plate part
surface grinding and
polishing device which comprises an advancing mechanism, a clamping mechanism, an
angle grinder and a guide rail, the advancing mechanism is arranged on the guide rail and can move along the guide rail, the clamping mechanism is installed on the advancing mechanism, the
angle grinder is installed on one side of the clamping mechanism, and the
angle grinder is installed on the other side of the clamping mechanism. The clamping mechanism comprises an angle grinder working angle adjusting
system and an angle grinder height adjusting
system. By means of the mode that acting force is applied through a mechanical structure, the
operation mode of a user is optimized, the
labor burden is relieved while the operation effect is fully guaranteed, accumulative injuries caused by the irregular appearance of the angle grinder to the hand are avoided,
machining treatment of to-be-machined faces of various shapes can be achieved, and the
machining efficiency is improved. The operation flexibility, the adaptability and the adjustability are extremely high. The guide rails can be assembled and disassembled according to requirements, high
assembly flexibility and coordination are achieved, and the transfer speed of the angle grinder and the whole
machine during
machining operation can be effectively increased.
