Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] The utility model provides an aluminum casting polishing machine, comprising a bracket 1, a limit frame 101 is symmetrically installed in the bracket 1, a screw rod 102 is rotatably connected to the limit frame 101, a servo motor 103 is fixedly connected to the bracket 1, a rotor 104 is rotatably connected to the servo motor 103, the rotor 104 is connected to the screw rod 102, a slider 2 is threadedly connected to the screw rod 102, the bottom of the slider 2 is fixedly connected to the oil cylinder 3, and the oil cylinder 3 is slidably connected to the slider. Rod 301, a polishing cylinder 4 is provided below the oil cylinder 3, a working seat 302 is fixedly connected to the bottom of the sliding rod 301, the size of the working seat 302 is smaller than that of the polishing cylinder 4, and hanging rings 303 are evenly distributed on the working seat 302, and an aluminum casting 304 is movably connected to the hanging ring 303. The bottom of the polishing cylinder 4 is fixedly connected to a driving motor 306, and a rotating shaft 307 is rotatably connected to the driving motor 306, and a stirring paddle 308 is fixedly connected to the rotating shaft 307.

[0019] When the aluminum casting 304 polishing machine is actually used, the aluminum casting 304 structure to be polished is installed on the hanging ring 303, and then the servo motor 103 drives the rotor 104 to start working, driving the screw rod 102 to rotate in the limit frame 101. The screw rod 102 is threadedly connected to the slider 2. When the screw rod 102 rotates, it drives the slider 2 to slide on the screw rod 102 and gradually moves to the upper position of the polishing cylinder 4. When it moves to the top of the polishing cylinder 4, the servo motor 103 stops driving, and then the oil cylinder 3 drives the slide rod 301 to drive the working seat 302 to move toward the polishing seat until the aluminum casting 304 is completely immersed in the polishing cylinder 4. In the polishing liquid, the polishing cylinder 4 is provided with a liquid inlet 305 for replenishing the polishing liquid to the polishing cylinder 4, and then the driving motor 306 at the bottom of the polishing cylinder 4 drives the stirring paddle 308 to rotate through the rotating shaft 307, so that the polishing liquid in the polishing cylinder 4 can be fully disturbed, and the aluminum casting 304 is fully immersed, thereby improving the polishing efficiency of the aluminum casting 304. Then, a staff member drives the oil cylinder 3 to drive the slide bar 301 upward until the aluminum casting 304 is separated from the polishing cylinder 4. At this time, the servo motor 103 works again through the relevant components to drive the slider 2 to continue sliding on the screw rod 102 until the aluminum casting 304 reaches the waste liquid. Above the collection box 5, after standing for a period of time, the aluminum castings 304 are removed one by one, and the bracket 1 structure is installed at the upper position of the polishing cylinder 4, and then the screw rod 102, slider 2 and limit frame 101 assembly structure for driving the left and right sliding are installed on the bracket 1 structure, and the slider 2 is driven to slide on the screw rod 102, thereby driving the oil cylinder 3 structure below the slider 2 to slide and adjust. When the oil cylinder 3 moves to the position just above the polishing cylinder 4, the oil cylinder 3 drives the slide rod 301 to drive the working seat 302 to move into the polishing cylinder 4 until the aluminum casting 304 is completely immersed in the polishing liquid. After a period of time , and then the oil cylinder 3 drives the aluminum casting 304 to reset, and then the servo motor 103 drives the screw rod 102 to drive the slider 2 to continue sliding on the screw rod 102 until the aluminum casting 304 moves to the upper position of the waste liquid collection box 5, completing the semi-automatic polishing process of the aluminum casting 304. Compared with the conventional method of polishing one by one by hand by the staff, the technical solution adopted by the utility model realizes the semi-automatic polishing process of the aluminum casting 304, liberates the labor intensity of the staff, can meet the polishing processing needs of large quantities of aluminum castings 304, and the overall structure is compact and easy for the staff to install and maintain.

A waste liquid collection box 5 is installed on the right side of the polishing cylinder 4, and a working distance is left between the waste liquid collection box 5 and the polishing cylinder 4.

[0021] The effect achieved by the entire embodiment 1 is that, during use, the provision of the waste liquid collection box 5 facilitates the centralized collection and treatment of waste liquid dripping from the polished aluminum casting 304 during the drying process.

[0022] Working principle: The aluminum casting structure to be polished is installed on the hanging ring, and then the servo motor drives the rotor to start working and drive the screw to rotate in the limit frame. The screw is threaded and connected to the slider. The rotation of the screw drives the slider to slide on the screw and gradually move to the upper position of the polishing cylinder. When it moves to the top of the polishing cylinder, the servo motor stops driving, and then the oil cylinder drives the slide rod to drive the working seat to move toward the polishing seat until the aluminum casting is completely immersed in the polishing liquid in the polishing cylinder. The polishing cylinder is provided with a liquid inlet for replenishing the polishing liquid to the polishing cylinder. Then the driving motor at the bottom of the polishing cylinder drives the stirring paddle to rotate through the rotating shaft, so that the polishing liquid in the polishing cylinder can be fully disturbed, and the aluminum casting is fully immersed, thereby improving the polishing efficiency of the aluminum casting. Then a staff member drives the oil cylinder to drive the slide rod upward until the aluminum casting is separated from the polishing cylinder. At this time, the servo motor works again to drive the slider to continue sliding on the screw rod through the relevant components until the aluminum casting reaches the top of the waste liquid collection box. After standing for a period of time, the aluminum castings are removed one by one.
