[0003] At the present stage, the turning method is used in the process of removing the skin of the magnesium alloy casting rods produced by the factory. However, the diameter of the casting rods produced by the mold in the factory workshop at present is 600 mm, and the length can be customized according to customer requirements, but the minimum length is 1200 mm. The length and weight of the magnesium alloy casting rods make it difficult to install and turn them. In the turning process, first use a crane to move the casting rod in front of the lathe, and then 3 to 4 workers are needed to assist in fixing one end of the casting rod on the chuck of the lathe, and the other end needs to cooperate with the tailstock mechanism of the lathe.

Next, slowly lower the large-sized magnesium alloy casting rod driven by the overhead crane and place the large-sized magnesium alloy casting rod on the support plate 25. Then, start the hydraulic cylinder 24 to descend, use the hydraulic cylinder 24 to drive the support plate 25 to descend, and adjust the height of the support plate 25 and the large-sized magnesium alloy casting rod to adjust the center point height of the large-sized magnesium alloy casting rod to be the same as that of the chuck 13.

[0046] Step 2: Adjust the centering device 3. First, start the motor 331 and adjust the horizontal displacement of the center rest 31 according to the specification length of the large-sized magnesium alloy casting rod. Open the lower part 311 and the upper part 312 of the center rest, and use the center rest 31 to clamp the other end of the large-sized magnesium alloy casting rod. The center rest roller 313 is in rolling fit with the large-sized magnesium alloy casting rod, which can ensure that the chuck 13 and the casting rod rotate coaxially. After the two ends of the casting rod are clamped, start the hydraulic cylinder 24 to descend and lower the hydraulic cylinder 24 to the lowest position to avoid interfering with the rotational movement of the large-sized magnesium alloy casting rod being turned.

[0047] Step 3: Start the lathe device 1, where the headstock 11, the feed box 12, and the chuck 13 start to work. Then, start the tool post 16 to turn the large-sized magnesium alloy casting rod. The turning work starts from the end clamped by the chuck 13 of the large-sized magnesium alloy casting rod to the end clamped by the center rest 31.

[0048] Step 4: Shut down the lathe device, where the headstock 11, the feed box 12, and the chuck 13 stop working. Then, open the chuck 13 and the center rest 31, start the hydraulic cylinder 24 to rise, return the center rest 31 to its original position, and use the overhead crane to move the turned casting rod to the next processing link.
