The X-axis 9 is located on the front of the vertical base 8 and is perpendicular to the X-axis 9. The X-axis 9 is driven by a linear guide rail and a servo motor to ensure the accuracy and speed of horizontal movement. A truss manipulator 10 is arranged above the Z-axis 3, and the truss manipulator 10 is fixedly connected to the horizontal base 5 by a bracket. A feeding mechanism 4 is arranged on the side of the truss manipulator 10 away from the vertical base 8. The feeding mechanism 4 is driven by a pneumatic device to achieve automatic loading and unloading of workpieces. The feeding mechanism 4 is perpendicular to the Z-axis 3 to ensure accurate positioning and stable transmission of the workpiece during processing.

[0024] The Z axis 3 includes a first motor 301, a first slide 302 and a first screw 303. The first motor 301 drives the first screw 303 to rotate. The first slide 302 is slidably connected to the first screw 303 through a nut to achieve precise movement along the Z axis. A spindle 1 is installed on one side of the first slide 302, and the spindle 1 is supported by a high-precision bearing to ensure the stability and accuracy of rotation. A chuck 2 is provided at one end of the spindle 1 for fixing and clamping the workpiece. The chuck 2 adopts a quick-change design to improve processing efficiency.

[0025] The X-axis 9 includes a second motor 901, a second slide 902 and a second screw rod 903. The second motor 901 drives the second screw rod 903 to rotate, thereby driving the second slide 902 to move precisely along the X-axis. The second slide 902 is slidably connected to the second screw rod 903 by a nut to ensure smooth operation. A groove is provided on the second slide 902, and a positioning hole and a fixing device are provided in the groove to facilitate the detachable installation of the first turning tool 6 and the second turning tool 7. By adjusting the fixing device, the spacing between the first turning tool 6 and the second turning tool 7 can be flexibly adjusted to meet different processing requirements and improve the flexibility and efficiency of processing.

[0026] The truss manipulator 10 includes a third motor 1001, a fourth motor 1002, a first rack 1003, and a second rack 1005.

The two sides of the telescopic cover 11 are fixedly connected to the housing of the spindle 1 and the vertical base 8, respectively, and can be telescopic with the movement of the spindle 1. The telescopic cover 11 is used to protect the moving parts of the spindle 1 and the Z-axis 3, prevent dust, chips and other debris from entering, ensure the cleanliness and normal operation of the equipment, and improve the service life and safety of the equipment.

[0031] The new type adopts a motion combination mode in which the spindle 1 moves horizontally along the Z axis 3 and the X axis 9 moves vertically to meet the production process requirements of different workpieces. The truss manipulator 10 and the feeding mechanism are integrated into the lathe to save space. The feeding mechanism is equipped with a feeding conveyor belt 402 and a discharging conveyor belt 403. The workpiece is placed on the feeding conveyor belt 402 for feeding. The truss manipulator 10 takes the material from the feeding conveyor belt 402 and moves to the chuck 2 position of the spindle. When an air claw removes the workpiece that has been processed on the chuck, the two air claws are swapped by controlling the swing cylinder 1008 so that the workpiece to be processed on the other air claw is installed on the chuck 2 to complete the material replacement action. The switching action is efficient and smooth, realizing fully automatic flow-type uninterrupted operation. The Z axis 3 drives the spindle 1 to move, the X axis 9 drives the turning tool to move, and the spindle 1 rotates to complete the workpiece cutting. The X axis 9 is equipped with a second slide 902, which can be installed with a variety of different turning tools. According to the processing technology requirements, different turning tools can be quickly switched to reduce the downtime waiting time.
