[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A CNC lathe worktable includes a table surface 1, a load-bearing assembly, and a clamping assembly. Support legs 2 are located at the four corners of the table surface 1. The load-bearing assembly includes a load-bearing roller 3, an elastic element, a baffle 4, and a rotating shaft 5. A hollow hole is located at the center of the table surface 1. Movable grooves are symmetrically arranged on the left and right sides of the load-bearing roller 3. The elastic element is connected at both ends to the inner wall of the movable groove and the baffle 4, respectively. A rotating shaft 5 is located at the end of the baffle 4 away from the elastic element. Several sets of guide grooves are symmetrically arranged on the left and right sides of the hollow hole. A load-bearing groove is located below the guide grooves. The rotating shaft 5 is rotatably connected to the load-bearing groove. An arc-shaped groove is located at the center of the load-bearing roller 3. The clamping assembly includes a threaded screw 6, a motor 7, a connecting block 8, a clamping plate 9, and a slider 10. The threaded screw 6 is rotatably mounted in the upper part of the hollow hole. The output end of the motor 7 passes through the platform 1 and is connected to the threaded screw 6. The threaded screw 6 is located above the arc-shaped groove. The bottom wall of the clamping plate 9 is flush with the top wall of the maximum outer diameter of the bearing roller 3. The clamping plate 9 is arranged in two sets symmetrically front and back. A connecting block 8 is also provided below the clamping plate 9 and threadedly connected to the threaded screw 6. Slider 10 is also provided on the lower left and right sides of the clamping plate 9. A sliding groove adapted to the slider 10 is also provided on the platform 1.

[0023] The table 1, as the core load-bearing component of the entire workbench, provides a flat and stable surface for the load-bearing components, clamping components, and mechanical parts to be processed. During part processing on the CNC lathe, all operations and forces rely on the table 1 for support and transmission. The four support legs 2 located at its lower corners play a crucial role in supporting the entire table 1. The support legs 2 lift the table 1, maintaining a certain distance from the ground. This ensures that the table 1 is level, creating conditions for accurate placement and processing of materials.

[0024] In actual use, the two sets of baffles 4 press against the bearing rollers 3, and the two sets of elastic elements contract. At this time, the two sets of rotating shafts 5 slide into the guide grooves, and the two sets of bearing rollers 3 protrude above the table surface 1. The material is placed on the bearing rollers 3. As the material moves, the bearing rollers 3 can rotate easily. The motor 7 (using a servo motor 7, which has the characteristics of high-precision control) serves as the power source. Its output end passes through the table surface 1 and is connected to the positive and negative thread screws 6. When the control signal is received and started, the motor 7 drives the positive and negative thread screws 6 to rotate. The positive and negative thread screws 6 are set above the arc groove of the bearing rollers 3, and the threads on both sides are in opposite directions. The connecting block 8 is threadedly connected to the positive and negative thread screws 6. The connecting block 8 is fixed below the clamping plate 9, and the sliders 10 on the left and right sides of the clamping plate 9 are located in the corresponding sliding grooves on the table surface 1. The sliders 10 can slide along the sliding grooves. Based on the characteristics of the forward and reverse threaded screw 6, when the forward and reverse threaded screw 6 rotates clockwise, the connecting blocks 8 on both sides will drive the clamping plates 9 to move towards each other along the slide groove via the slider 10; when the forward and reverse threaded screw 6 rotates counterclockwise, the clamping plates 9 will move away from each other. In actual operation, for mechanical parts of different diameters, lengths and other specifications, by controlling the motor 7 to rotate precisely at a certain angle or number of turns, the clamping plates 9 can be accurately moved to the appropriate position, closely fitting the side of the material, and achieving stable clamping of the material.

[0025] In this embodiment, the elastic element includes a spring 11 and a telescopic rod 12. The spring 11 is sleeved on the telescopic rod 12. Both ends of the spring 11 and the telescopic rod 12 are respectively connected to the inner wall of the movable groove and the baffle 4. The spring 11 facilitates the reciprocating movement of the baffle 4, and the telescopic rod 12 ensures the stability of the movement of the baffle 4. Several sets of arc-shaped blocks 13 are also provided at the end of the baffle 4 away from the elastic element to facilitate rotation.

[0026] In actual use, side plates 14 are provided on the left and right sides of the clamping plate 9 near the center of the slide groove. The side plates 14 prevent the material from slipping off the left and right sides of the two sets of clamping plates 9. A buffer pad 15 connected to the clamping plate 9 is also provided between the two sets of side plates 14 to ensure that it can stably clamp the material.

[0027] The perforated holes facilitate the falling of waste chips, allowing for stable subsequent material feeding and securing with the clamping components, making operation convenient.
