Abstract
Description
Technical Field
[0001] The present application relates to the technical field of grinding equipment, and in particular to a grinding equipment for a double-support crankshaft. Background Art
[0002] The crankshaft is the most important component in the engine. It bears the force transmitted from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the combined effects of the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and grinding equipment is needed during its processing.
[0003] In actual use, existing grinding equipment is not convenient for absorbing the fine dust generated during grinding, which causes the dust to float freely in the air, resulting in substandard hygiene in the workplace. If the dust is accidentally inhaled into the lungs by workers, it will threaten their life safety. In addition, large-volume debris is easily splashed to the ground during the grinding process, making it difficult to collect. Utility Model Content
