[0073] In this embodiment, the working principle of the dual-spindle automatic docking processing lathe is as follows: start the motor 8, the motor 8 drives the threaded rod 7 to rotate, and as the threaded rod 7 rotates, the support rod 9 drives the arc-shaped protective cover 5 to move, and at this time the arc-shaped protective cover 2 6 moves along with it. After the arc-shaped protective cover 1 5 and the arc-shaped protective cover 2 6 move to a certain position, one end of the workpiece is placed on the chuck of the fixed spindle 2, and the motor 2 13 is started, and the motor 2 13 drives the threaded rod 2 12 to rotate. As the threaded rod 2 12 rotates, the connecting frame drives the arc-shaped protective cover 2 6 to move in the direction of the arc-shaped protective cover 5 until the docking rod slides into the docking hole. At this time, one end of the workpiece is located inside the arc-shaped protective cover 5 and the arc-shaped protective cover 2 6, and then the tool 4 is passed through the opening The second 31 extends into the arc-shaped protective cover 26, and then the workpiece is cut through the tool 4.

After the debris in the packing box 24 reaches a certain amount, the cylinder 25 is started, and the cylinder 25 drives the lower pressure plate 26 to move in the direction of the packing box 24 to compress and pack the debris. When the workpiece is cut, the blower 27 is started, and the smoke pipe 2 is blown by the blower 27. 8 generates suction to collect the smoke in the arc-shaped protective cover 1 5 and the arc-shaped protective cover 2 6, and connects the blower 27 with the dust removal equipment. The blower 27 blows the smoke into the dust removal equipment for processing. After processing one end of the workpiece, start the mobile spindle 3, and then move the tool 4 away from the inside of the arc-shaped protective cover 2 6 through the opening 2 31. At this time, the motor 2 13 drives the threaded rod 2 12 to rotate, so that the arc-shaped protective cover 2 6 rises, so that the chuck of the mobile spindle 3 can clamp the other end of the workpiece, and then fix the spindle 2 to release the workpiece, and then start the motor 2 13. The motor 2 13 drives the threaded rod 2 12 to rotate. As the threaded rod 2 12 rotates, the arc-shaped protective cover 2 6 is docked with the arc-shaped protective cover 1 5, and then the cutting process is performed by the tool 4.

[0074] It should also be noted that, in order to ensure the service life of the blower 27, a filtering device can be installed at the connection between the blower 27 and the smoking pipe 28 to filter out dust in the smoke.

[0075] It should also be noted that the input end of the water pump 22 needs to be connected to a water source, through which most of the cooling water is provided.
