The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0022] Reference Figures 1 to 5In the embodiment of the utility model, a feeding mechanism of a CNC lathe includes: a base 1, the base 1 is movably connected with a connecting rod 2, a spring 3 is arranged at the outer end of the connecting rod 2, the other end of the connecting rod 2 is fixedly connected with a receiving tray 4, the other end of the base 1 is fixedly connected with an X-axis linear driver 5, the movable end of the X-axis linear driver 5 is fixedly connected with a Y-axis linear driver 6, the movable end of the Y-axis linear driver 6 is fixedly connected with a storage box 7, the side end of the storage box 7 is fixedly connected with a hydraulic rod 8, the movable end of the hydraulic rod 8 penetrates the storage box 7, and is fixedly connected with a push plate 9, the rear end of the storage box 7 is fixedly connected with a fixed block 10, one end of the fixed block 10 A hydraulic rod 11 is fixedly connected, and the movable end of the hydraulic rod 11 passes through the storage box 7 and is fixedly connected to a push plate 12. A discharge hole 13 is provided at the front end of the storage box 7. A workpiece 14 to be processed is movably connected to the inner end of the storage box 7. A tool fixing table 15 is provided at the side end of the storage box 7. The tool fixing table 15 is movably connected to the movable end of the Y-axis linear driver 6. A tool handle 16 is fixedly connected to the front end of the tool fixing table 15. Limit blocks 17 are provided at both ends of the tool fixing table 15. The limit blocks 17 are fixedly connected to the movable end of the Y-axis linear driver 6. The tool fixing table 15 is clamped with the limit blocks 17. A three-jaw chuck 18 is fixedly connected to the upper end of the base 1.

[0023] Reference Figures 1 to 5 There are two groups of discharge holes 13, which are symmetrically opened at both ends of the storage box 7. There are multiple groups of connecting rods 2 and springs 3, which are evenly distributed on the side ends of the receiving tray 4. The bottom end of the receiving tray 4 is fixedly connected with a guide plate 41. The inner end of the storage box 7 is clamped with a limiting plate 71. The limiting plate 71 is located at one end of the discharge hole 13 and fits with the inner wall of the storage box 7. The pushing plate 12 is adapted to the discharge hole 13.

[0024] The above scheme is adopted: the workpiece 14 to be processed at the discharge hole 13 can be pushed into the three-jaw chuck 18 through the hydraulic rod 11 and the push plate 12, and the workpiece 14 to be processed in the storage box 7 can be pushed through the hydraulic rod 18 and the push plate 19, to ensure that the workpiece 14 to be processed is always at the discharge hole 13, so as to realize automatic loading, and the connecting rod 2 and the spring 3 can shrink when the receiving tray 4 contacts the external force and enter the lower end of the three-jaw chuck 18, so as to prevent the receiving tray 4 from interfering with its movement trajectory when the X-axis linear drive 5 and the Y-axis linear drive 6 move.

[0025] The working principle of the utility model is as follows: when in use, multiple groups of workpieces 14 to be processed are first placed in the material storage box 7, and the first group of workpieces 14 to be processed are aligned with the discharge hole 13 through the limit plate 71, and then the first group of workpieces 14 to be processed are moved to the corresponding position of the three-jaw chuck 18 through the X-axis linear drive 5 and the Y-axis linear drive 6. During the movement, the Y-axis linear drive 6 will push the receiving plate 4 to retract the connecting rod 2 into the base 1 and shrink the spring 3. Then, the first group of workpieces 14 to be processed are pushed out from the discharge hole 13 and enter the three-jaw chuck 18 through the hydraulic rod 11 and the push plate 12. After that, the three-jaw chuck 18 is controlled to clamp the workpieces 14 to be processed, and then the workpieces 14 to be processed can be processed. After the first group of workpieces 14 to be processed are pushed out, the hydraulic rod 18 and the push plate 19 push the other workpieces 14 to be processed to move, so that the second group of workpieces 14 to be processed are moved to After the first group of workpieces 14 to be processed are positioned, and after the workpieces 14 to be processed are processed, the X-axis linear drive 5 and the Y-axis linear drive 6 return to their initial positions, so that the spring 3 pushes the receiving tray 4 out to the side end of the three-jaw chuck 18. At this time, the three-jaw chuck 18 is controlled to open, so that the workpieces 14 to be processed fall into the receiving tray 4 and are discharged through the guide plate 41; the workpieces 14 to be processed at the discharge hole 13 can be pushed into the three-jaw chuck 18 by the hydraulic rod 2 11 and the push plate 2 12, and the workpieces 14 to be processed in the storage box 7 can be pushed by the hydraulic rod 1 8 and the push plate 1 9, so as to ensure that there are always workpieces 14 to be processed at the discharge hole 13, and automatic loading is realized. The connecting rod 2 and the spring 3 can be used to shrink the receiving tray 4 when it contacts external force and enter the lower end of the three-jaw chuck 18 to prevent the receiving tray 4 from interfering with its movement trajectory when the X-axis linear drive 5 and the Y-axis linear drive 6 move.
