[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the Z-axis slide and tailstock are driven by ball screws in conjunction with servo motors. The ball screws are characterized by high transmission efficiency and smooth movement, while the servo motors can achieve precise speed and position control. The combination of the two ensures accurate positioning and smooth operation of the Z-axis slide and tailstock during movement, effectively reducing motion errors and vibrations and improving processing efficiency. At the same time, the use of linear guides provides stable support and guidance for the movement of the slide and tailstock, further enhancing the stability and reliability of the movement.

[0014] In this invention, the tailstock uses a rotating adjusting screw to drive the round nut to precisely adjust the spring force, thereby accurately controlling the spring force of the tip, ensuring stable workpiece clamping, and reducing machining errors caused by unstable clamping. The bolted connection design of the transverse and longitudinal adjusting blocks allows for adjustment of the tip's position in the longitudinal and transverse directions, enabling the tip to be precisely aligned with the workpiece center, further improving machining accuracy and meeting the requirements of high-precision machining.

A platform is milled in the shaft of the tailstock sleeve 10, and a pressure block 11 is pressed on the platform in the shaft of the tailstock sleeve 10 to prevent the tailstock sleeve 10 from rotating relative to the shaft.

[0022] like Figures 1-3As shown, a spring 12 is installed inside the tailstock sleeve 10. An adjusting screw 14 and a round nut 13 are arranged in the middle of the spring 12. When the adjusting screw 14 is rotated, the round nut 13 can move relative to the adjusting screw 14 in both directions, thereby adjusting the elastic force of the spring 12 and ultimately adjusting the elastic force of the tip 7. A tailstock ball screw 3 is installed on the lower part of the C-axis rotary table 2. A tailstock servo motor 17 is arranged on one end of the tailstock ball screw 3 outside the Z-axis slide 1.

The metal protective cover 5 is telescopic and movable to protect the tailstock ball screw 3. A Z-axis linear guide rail 21 is installed at the lower end of the Z-axis slide 1. The Z-axis slide 1 is mounted on the Z-axis linear guide rail 21. A Z-axis ball screw 20 is installed at the lower part of the Z-axis slide 1.

When it is necessary to adjust the elastic force of the tailstock tip 7, the adjusting screw 14 is rotated to make the round nut 13 move in the forward and reverse directions, changing the compression of the spring 12, thereby adjusting the elastic force of the tip 7. During the processing, according to the processing requirements, the Z-axis servo motor 18 drives the Z-axis ball screw 20 through the coupling 19, which drives the Z-axis slide to move in the Z direction along the Z-axis linear guide 21. The tailstock servo motor 17 drives the tailstock ball screw 3 through the coupling 16, which drives the tailstock to move along the tailstock linear guide 4, thereby realizing the clamping and processing operation of the workpiece.
