Automatic loading and unloading mechanism of full-automatic curved surface weld seam polisher

The invention discloses an automatic loading and unloading mechanism of a full-automatic curved surface weld seam polisher. An automatic controller (14) is connected with a hydropress (13) and a stepping motor (5). A work-piece (3) is moveably arranged between a clamp seat (11) and a clamp cover (12) and is moveably connected with the hydropress (13) via a hydraulic lever. An incomplete loading gear (1) is arranged in the middle of a first gear shaft (2) and is meshed with a complete gear (4). The complete gear (4) and an unloading wheel (8) are connected with the stepping motor (5) through a second gear shaft (6). A loading basket (7) is arranged at the right upper end of the incomplete loading gear (1). A material-receiving basket (10) is arranged on the left lower part of the unloading wheel (8). By adopting the full-automatic grinding, loading and unloading device, grinding precision and work efficiency of curved surface weld seams are improved, labor intensity is lowered and production cost is reduced.
