Continuous grinding device

The utility model provides a continuous grinding device, relates to the technical field of grinding devices, and aims to solve the problems that a crankshaft mounting structure in an existing crankshaft grinding device is imperfect, a crankshaft needs to be disassembled and remounted after a group of crankshafts are ground during use, the period of time is not fully utilized, the crankshaft grinding is not coherent, and the grinding efficiency is high. The crankshaft grinding device comprises a mounting mechanism, and the mounting mechanism comprises a main frame and a guide groove, two sets of rectangular plate-shaped structures are arranged in the middle of the upper end of the main frame, a polishing roller is rotationally mounted between the two sets of plate-shaped structures, and the outer end of the polishing roller can be externally connected with a motor. In the using process, two sets of crankshafts can be installed at the same time, the rear crankshaft is directly pushed to a machining area after t
