During specific use, two second motors 7 can be selected to be activated at the same time, or only one of them can be activated according to the structure of the aluminum alloy casting 26 and the part to be polished.

[0029] In this embodiment, a first support frame 8 is fixedly mounted on the base 1, a cylinder 9 is fixedly connected to the first support frame 8, and an output end of the cylinder 9 is fixedly connected to a tooling cover 10 corresponding to the tooling base 6, which is used to press the aluminum alloy casting 26 to be processed.

[0030] In this embodiment, first slide rails 11 are fixedly provided on both sides of the chain 5 , the first slide rails 11 are fixedly connected to the base 1 , a first slider 12 is slidably connected to the first slide rails 11 , and the first slider 12 is fixedly connected to the second motor 7 .

[0031] In this embodiment, a third motor 13 is fixedly provided on the base 1, and the output shaft of the third motor 13 is fixedly connected to a screw 14, which is threadedly connected to the first slider 12. The third motor 13 rotates, driving the screw 14 to rotate, thereby causing the first slider 12 and the second motor 7 to move along the first slide rail 11.

[0032] In this embodiment, a second support frame 15 is provided at both ends of the chain 5 in the running direction, and the second support frame 15 is fixedly connected to the base 1. Protective side plates 16 are provided in parallel on both sides of the chain 5, and the protective side plates 16 are fixedly connected to the second support frame 15.
