The invention relates to the technical field of
crankshaft machining equipment, in particular to an automatic automobile
crankshaft grinding device. The automatic automobile
crankshaft grinding devicecomprises a bottom plate, side supporting plates are connected to the left side and the right side of the upper end face of the bottom plate, and a
workbench is arranged above the bottom plate; a hydraulic telescopic rod is connected between the bottom plate and the
workbench, a controller is installed on the side face of one of the side supporting plates, the hydraulic telescopic rod is electrically connected with the controller, a
grinding motor is arranged above the
workbench, an output shaft of the grinding motor is connected with a grinding disc, and the grinding motor is electrically connected with the controller; and the automatic automobile crankshaft grinding device further comprises a moving mechanism and a clamping mechanism. The moving mechanism can drive the grinding motor and the grinding disc to reciprocate left and right to automatically
grind an automobile crankshaft, the automobile crankshaft can be clamped through the clamping mechanism, the situation that in the
grinding process, the automobile crankshaft moves, and consequently the
grinding process is affected is avoided, and the
automation degree is high.
