The utility model discloses an automatic
grinding and cap replacing all-in-one
machine for a
welding electrode, which comprises a support frame, a driving gear box, a
grinding mechanism and a cap replacing mechanism, and is characterized in that the top of the support frame is provided with a driving gear box; a driving motor; a cap replacing body and a
grinding and shaping cutter body are installed at the top of the driving gear box, an air blowing
nozzle is installed at the side line of the top of the driving gear box through a supporting plate, a pneumatic ejection clip is installed on the side of the top of the supporting frame, a second sensor is installed at the top of the pneumatic ejection clip, and a first sensor is arranged above the second sensor. By means of the arrangement mode that the cap replacing body and the grinding and shaping cutter body are matched, a grinding
machine product is different from an existing
electrode cutting, coping and cap replacing mode, a
grinding process is adopted, grinding and shaping are achieved, a hard
oxide layer on the surface of an
electrode cap can be effectively removed through the shaping mode, higher shaping quality and precision are obtained, and the
machining efficiency is improved. And meanwhile, the resistance of the electrode cap is reduced in the
welding process, and the
welding quality and stability are greatly improved.
