Abstract

The invention belongs to the technical field of polishing equipment, and particularly discloses a crankshaft polishing machine. The crankshaft polishing machine comprises a worktable, a motor, a crossbeam, a first ejector pin and a second ejector pin, wherein a stand column, an air cylinder and a supporting rod are arranged on the worktable, a supporting table is arranged on a piston rod of the air cylinder, a first supporting rod, a first grinding wheel, a second supporting rod and a second grinding wheel are arranged on the upper portion of the supporting rod, a sliding hole is formed in the middle of the stand column, and a sliding block is arranged inside the sliding hole; and a connecting rod is hinged to the sliding block, one end of the connecting rod is hinged to clamping plates,torsion springs are arranged between the two clamping plates and the connecting rod, and the two clamping plates are abutted against each other when the torsion springs are in a natural state, and anair outlet communicating with a plurality of sliding holes are formed in one side, close to the motor, of the stand column in the length direction. According to the machine, the crankshaft polishing machine is mainly used for polishing the crankshaft, the problem that the polishing effect is influenced due to the fact that scraps are prone to splash to a center drilling hole during polishing of the crankshaft is solved.

Description

technical field [0001] The invention belongs to the technical field of polishing equipment, and specifically discloses a crankshaft polishing machine. Background technique [0002] The crankshaft mainly includes the main journal and the connecting rod journal, and the crankshaft is the most important part of 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. [0003] CNC lathes, CNC internal milling machines, CNC lathes and other advanced ...
