[0034] Specifically, in the process of fixing the workpiece, first, the workpiece is accurately placed on the pressing plate 14 to ensure stable support. Then, the pressing plate 14 drives the wedge-shaped clamping block 8 to move down synchronously through the downward action. When the wedge-shaped clamping block 8 slides in the wedge-shaped block 7, it provides stable pushing force through its special wedge-shaped design, ensuring the workpiece is firmly fixed. The wedge-shaped block 7 smoothly slides on the track two 6, driving the frame 9 to cooperate with the connecting rod one 11, and through the rotation of the connecting rod two 12, accurately moves the clamping plate one 13 and accurately limits the workpiece. At the same time, the telescopic rod 18 tightly fits the bottom of the clamping plate two 16 to the outer wall of the workpiece through its tension support, further ensuring the stability of the workpiece during the fixing process.

[0035] Referring to Figure 4 The lathe body 1 top is slidably connected with a base two 20, and a limiting ring 21 is rotatably connected inside the base two 20. The rotatable connection of the limiting ring 21 allows the base two 20 to move relatively within a certain range, thereby driving the adjustment of the entire feeding system. A fixed block one 22 is rotatably connected inside the base two 20. The rotatable connection of the fixed block one 22 helps to stabilize the position of the base two 20 and can effectively transmit power. A fixed block two 25 is rotatably connected on one side of the limiting ring 21. The rotatable connection of the fixed block two 25 provides the ability to move relative to the limiting ring 21, so that the entire feeding system can be flexibly adjusted to meet the feeding needs of different workpieces. A motor two 23 is fixedly connected on one side of the fixed block one 22. The motor two 23 serves as a driving source, and its output end is fixedly connected with a threaded rod two 24. The motor two 23 drives other components for accurate control through the threaded rod two 24. The threaded rod two 24 is threadedly connected inside the fixed block two 25. The threaded connection structure converts the output rotary motion of the motor two 23 into linear motion, ensuring accurate and smooth positioning during feeding. A sleeve 27 is rotatably connected inside the limiting ring 21. The sleeve 27 can allow the connecting part to rotate inside the limiting ring 21, thereby changing the working state of the feeding device. A connecting rod three 26 is provided inside the sleeve 27. One end of the connecting rod three 26 is rotatably connected inside the base two 20, providing a fixed connection between the base two 20 and the connecting rod three 26 to ensure stability during feeding. The other end of the connecting rod three 26 is rotatably connected with a limiting wheel 28. The limiting wheel 28 contacts the workpiece during work to ensure that the position of the workpiece is accurately limited during feeding, preventing the workpiece from shifting or being inaccurately positioned, further improving the accuracy and efficiency of the feeding device.

[0036] Specifically, in the operation of limiting the workpiece, first, the workpiece is accurately inserted into the inside of the base two 20 to ensure the accuracy of the initial position of the workpiece during the machining process. Then, the output end of the motor two 23 starts to drive the threaded rod two 24 to rotate, and the threaded rod two 24 effectively drives the fixed block two 25 through its screw transmission structure, realizing the stable rotation of the limiting ring 21 inside the base two 20. During the rotation of the limiting ring 21, the sleeve 27 is further driven to operate in linkage through the structural design of the base two 20. At the same time, the sleeve 27 drives one end of the connecting rod three 26 to move through the ingenious transmission design, so that the limiting wheel 28 is stably attached to the outer wall of the workpiece. The limiting wheel 28 provides a stable limiting effect for the workpiece through accurate contact with the outer wall of the workpiece, preventing any deviation or loosening of the workpiece during subsequent machining.

[0037] Working principle: when the feeding device of the numerical control lathe is used, first, fix the workpiece, place the workpiece on the pressing plate 14, then press the pressing plate 14 to drive the wedge-shaped clamping block 8 to press down, the wedge-shaped clamping block 8 slides in the wedge-shaped block 7, the wedge-shaped block 7 slides on the track two 6, then the wedge-shaped block 7 drives the frame 9 to rotate through the connecting rod one 11, the connecting rod two 12, the clamping plate one 13 limits the workpiece, and the tension of the telescopic rod 18 supports the clamping plate two 16 to limit the workpiece, then the output end of the motor one 3 drives the threaded rod one 4 to rotate, the threaded rod one 4 moves the feeding on the top of the base one 5 through the base one 5, achieving the effect of automatic feeding and adapting to different sizes of workpieces.

[0038] When the workpiece is limited, the workpiece is inserted into the inside of the base two 20, then the output end of the motor two 23 drives the threaded rod two 24 to rotate, the threaded rod two 24 drives the limiting ring 21 to rotate inside the base two 20 through the fixed block two 25, the base two 20 drives the limiting wheel 28 at one end of the connecting rod three 26 to attach to the outer wall of the workpiece through the sleeve 27, achieving the effect of limiting the workpiece.
