Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic cleaning machine equipment, in particular to an ultrasonic cleaning machine with a self-centering function. Background Art

[0002] The working principle of ultrasonic cleaning machine is mainly based on the cavitation effect produced by ultrasonic waves in liquid. When the ultrasonic generator emits a high-frequency oscillation signal, it is converted into high-frequency mechanical oscillation by the transducer and transmitted to the cleaning liquid, countless tiny bubbles will be formed in the cleaning liquid. These bubbles grow rapidly and suddenly burst under the action of ultrasonic waves, generating extremely strong impact force, which can completely remove stains on the surface of objects and in tiny gaps.

[0003] As disclosed in the utility model patent with publication number: CN220497150U, a fully automatic ultrasonic cleaning machine includes a cleaning machine, wherein a partition is installed on the inner side of the cleaning machine. The utility model is equipped with a motor. When the staff starts the motor, the output end of the motor drives the rotating rod to rotate with the rotating rod as the center of the circle, and the rotating rod drives the cam to rotate. When the distance from the edge of the top of the cam to the center of the circle of the rotating rod is the shortest, the rotating rod rotates to gradually increase the distance from the edge of the top of the cam to the center of the circle of the rotating rod. At this time, the cam drives the circular tube to move upward, so that the circular tube drives the support plate to move upward under the action of the cam. When the distance from the edge of the top of the cam to the center of the circle of the rotating rod is the longest, the circular tube will drive the support plate downward as the rotating rod continues to rotate, so that the support plate drives the placement frame to move up and down, and at the same time, the rotating rod drives the pillar to rotate through the sprocket and chain, so that the pillar drives the fan to rotate with itself as the center of the circle, and the fan blows water to take away the dirt inside the placement frame, thereby improving the cleaning effect.

[0004] Although the above-mentioned equipment can clean the workpiece, the cleaning basket in the above-mentioned equipment is a fixed structure, so that when the workpiece inside the cleaning basket is cleaned, its contact area with the cleaning liquid inside the ultrasonic cleaning machine is limited, thereby reducing the cleaning efficiency. In addition, the above-mentioned cleaning basket is not convenient for high-speed rotation and diversion with the cleaning liquid to further improve the efficiency of removing dirt from the outside of the workpiece. Therefore, there is an urgent need for an ultrasonic cleaning machine with a self-centering function to solve the above-mentioned problems. Utility Model Content

[0011] Preferably, a fixed slot is provided at the center of the inner end surface of the driven gear, and the cleaning basket is slidably engaged with the interior of the driven gear through the fixed slot, which can improve the convenience and stability of the subsequent alignment and engagement of the cleaning basket with the interior of the driven gear.

[0012] Preferably, the cleaning basket is adapted to the positioning card slot through the positioning card shaft and is then slidably engaged with the inside of the driven gear.
