The invention relates to a fully-enclosed automatic industrial component cleaning and oil sealing machine, and is characterized in that the machine comprises a cleaning bin, a main transmission system, a refrigeration system, an air passage drying reclaiming system, a liquid storage tank and a grease box, a filter, a distillation reclaiming system or a vacuum distillation reclaiming system, a carbon adsorption reclaiming system, as well as an ultrasonic generating device. The machine has the advantages that full-automatic control is realized, and the cleaning and the oil sealing are performed without the need of manpower, so that the labor intensity is reduced; the problems of easy flammability, insecurity and poor labor conditions caused by using gasoline, kerosene and alkaline solution as cleaning liquid are avoided; furthermore, the machine has the characteristics of an fully-enclosed structure and the vacuum distillation reclaiming system, thereby repeatedly utilizing a cleaning solvent, reducing the loss of the cleaning solvent, preventing people from direct contact with the cleaning solvent, and reducing environmental pollution and human body injuries; therefore, an organic solvent can be repeatedly used; meanwhile, the cyclic cleaning is performed by utilizing a combination of chemical force and various types of physical force, thereby enhancing the cleaning efficiency.
