Abstract

This invention relates to a vibrating abrasive cleaning apparatus and method which is powered by a hydraulic drive motor mounted to a square tubing frame which is housed within an enclosure that is vibrated by an eccentric shaft assembly directly coupled to the hydraulic drive motor and square tubing frame. The container assembly is mounted on the rigid square tubing frame, on one side by compression springs, on the opposite side by tension springs. The compression springs and tension springs have a different spring rate which produces better rolling of the media and therefore, faster parts circulation and cleaning. To further give flexibility to the cleaning process the hydraulic power supply is equipped with the variable volume piston pump to give infinite speed settings. The eccentric shaft assembly with the eccentric weight positions set at different relative positions to one another gives the operator the ability to adjust the machine to produce optimum results with all parts, sizes, and weights. The entire vibration assembly sits on a base and has a lid operated by a cable and counterweight for ease in loading the container for oscillation of the parts. Further, the vibrating abrasive cleaning apparatus and method provides a unique interchangeable drainage assembly for recirculation of and filtering of the cleaning solvent used in the cleaning process.
