The invention discloses a crankshaft grinding device. The crankshaft grinding device comprises a working assembly, wherein the working assembly comprises a first telescopic rod, a second telescopic rod and distance adjusting discs, the second telescopic rod is provided with a channel for allowing the first telescopic rod to be fed, one end of the first telescopic rod enters the second telescopic rod, the first telescopic rod can slide relative to the second telescopic rod, a positioning groove and a locking plate are arranged on the side wall of the second telescopic rod, the positioning groove makes the inner side and the outer side of the side wall of the second telescopic rod communicate, the locking disc is located in the positioning groove, one end of the locking disc is connected tothe outer wall of the first telescopic rod, and the first telescopic rod and the second telescopic rod are connected to the adjacent distance adjusting discs correspondingly. According to the crankshaft grinding device, a grinding disc can be conveniently adjusted to adapt to the position of a crankshaft journal, through a grinding block and a cleaning hole of the grinding disc, the grinding efficiency is improved.
Description
technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a crankshaft grinding device. Background technique [0002] The crankshaft is the most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque through the crankshaft output and drives other accessories on the engine to work. The crankshaft is subjected to the joint action of the centrifugal force of the rotating mass, the periodically changing gas inertial force and the reciprocating inertial force, so that the crankshaft is subjected to the bending torsional load. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, work evenly, and have good balance. During the working stroke of the crankshaft, the thrust transmitted by the connecting rod is first turned into a rotating torque, and the vehicle is driven through the transmissi...
