[0002] Aluminum alloy die castings refer to aluminum alloy parts produced using pressure casting technology. This process relies on pressure casting equipment equipped with a casting mold. After the aluminum alloy heated to a liquid state is poured into the input port of the die casting machine, it undergoes a high-pressure casting process of the die casting machine to eventually form aluminum alloy parts with a shape and size that meets the mold restrictions. A clamping device is usually used when processing aluminum alloy die castings.

[0003] Generally speaking, when using a clamping device to fix an aluminum alloy die-casting, it is necessary to put the positioning hole of the aluminum alloy die-casting on the outside of the positioning column on the processing table, and then use the clamping plate on the clamping device to clamp the aluminum alloy die-casting at the center position of the processing table to ensure the processing accuracy of the aluminum alloy die-casting.

The screw rod 17 inside the slide groove 2 12 and the bidirectional screw rod 15 inside the slide groove 11 are threadedly connected with a clamping assembly.

[0026] The aluminum alloy die-casting is placed on the processing table 2, so that the positioning hole of the aluminum alloy die-casting is covered with the positioning component, and then the positioning component supports the positioning hole, and then the bidirectional screw rod 15 is rotated by driving the motor 14 to drive the front and rear two clamping components to clamp the front and rear ends of the aluminum alloy die-casting, and then the left screw rod 17 and the gear 2 18 are rotated by driving the motor 2 16.

[0030] When the two screw rods 17 rotate synchronously, the left and right sliders 21 are driven to move relative to each other, so that the left and right clamping plates 28 clamp the left and right ends of the aluminum alloy die-casting. When the bidirectional screw rod 15 rotates, the front and rear sliders 21 are driven to move relative to each other, so that the front and rear clamping plates 28 clamp the front and rear ends of the aluminum alloy die-casting. When turning over, the front and rear clamping plates 28 or the left and right clamping plates 28 are separated from the aluminum alloy die-casting by driving the motor 14 or the motor 2 16, and then the aluminum alloy die-casting is turned over by the cooperation of the left and right driving members 25 and the electric telescopic rod 22 or the front and rear driving members 25 and the electric telescopic rod 22.
