[0002] The crankshaft grinder is the key equipment for finishing the crankshaft connecting rod neck of the automobile engine. In the prior art, the crankshaft is usually ground by using the eccentric fixture type crankshaft grinder, but the existing eccentric fixture type crankshaft grinder is usually in the middle of the upper end face of the machine base. The right side of the machine is equipped with a grinding wheel frame, which is equipped with a grinding wheel motor, and the motor shaft of the grinding wheel motor is equipped with a grinding wheel. The horizontal guide rail is installed on the machine base, and the table uses a screw drive unit to drive it to move horizontally on the machine base along the left and right directions. Since only one grinding wheel is used for grinding, the production efficiency is low and it is difficult to meet the requirements of the enterprise.
