It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0026] Please see attached Figure 1 and attached Figure 2 As shown, an automatic feeding device for a CNC lathe comprises a feeding channel 4, a worktable 1 installed on the machine tool and movable along the x-axis and the y-axis, and a vertically fixed mounting seat 3, wherein the upper end of the feeding channel 4 is connected to a vibration plate, and the products are automatically arranged in a certain direction and fed through the vibration of the vibration plate, and the products coming out of the vibration plate enter the feeding channel 4, and the mounting seat 3 is fixed and immovable, and the feeding channel 4 is fixed on the mounting seat 3 through a plurality of support plates;

[0027] The machine tool chuck 2 and the pushing mechanism 5 are fixed on the surface of the mounting seat 3. The pushing mechanism 5 is used to push the products in the unloading channel 4 out one by one. The pushing mechanism 5 includes a pushing block 51 and a slider 52 slidably connected to the mounting seat 3. The pushing block 51 is fixed to one end of the slider 52 and is placed below the bottom outlet of the unloading channel 4. The pushing block 51 is provided with a material through hole 53. The other end of the slider 52 is connected to a return spring 54.

[0028] The workbench 1 is provided with a material receiving mechanism 6, which is used to transfer the product pushed out by the material pushing mechanism 5 to the machine tool chuck 2, and the machine tool drives the workbench 1 to move, and then the workbench 1 drives the material receiving mechanism 6 to receive the material; wherein, the material receiving mechanism 6 includes a material receiving block 61, and the upper surface of the material receiving block 61 is provided with a material receiving hole 62, and the side of the material receiving block 61 facing the mounting seat 3 is provided with a discharge port 63 connected with the material receiving hole 62, and the upper surface height of the material receiving block 61 is lower than the lower surface height of the material pushing block 51, so that the material receiving block 61 can move back and forth under the material pushing block 51;

[0029] In the initial stage, the bottom end of the material discharge channel 4 is aligned with the side of the material through hole 53, and the bottom end of the material discharge channel 4 is placed on the surface of the pushing block 51, and the product in the material discharge channel 4 is blocked by the surface of the pushing block 51, so as to block the next product from being discharged, so that the products are discharged one by one;

[0030] In the unloading stage, the workbench 1 drives the receiving block 61 to move toward the slider 52 and pushes the slider 52 to squeeze the return spring 54. The slider 52 moves and drives the receiving block 61 to move until the bottom end of the unloading channel 4 is aligned with the material through hole 53. The product falls from the unloading channel 4 into the material through hole 53. At this time, a part of the surface of the receiving block 61 is still placed below the material through hole 53, and the outlet of the material through hole 53 is blocked by the upper surface of the receiving block 61 to prevent the product from falling out of the material through hole 53.

[0031] During the reset stage, the workbench 1 drives the receiving block 61 to move away from the slider 52. At the same time, the slider 52 also moves toward the receiving block 61 under the action of the rebound force of the reset spring 54. During the movement, the receiving hole 62 is aligned with the material through hole 53 so that the product falls from the material through hole 53 into the receiving hole 62 until the pushing block 51 returns to the initial position and the slider 52 stops moving.

[0032] As attached Figure 1 As shown, the pushing mechanism 5 also includes a fixed plate 55 and a slide rail 56 horizontally arranged on the mounting seat 3. The slider 52 is provided with a slide groove cooperating with the slide rail 56. Preferably, the slide rail 56 is in a dovetail shape, that is, the slide groove is a dovetail groove. The dovetail-shaped slide rail 56 can effectively ensure the stability between the slider 52 and the slide rail 56, and a guide rod 57 is provided at one end of the slider 52 near the fixed plate 55, and one end of the guide rod 57 passes through the fixed plate 55. The return spring 54 is sleeved on the guide rod 57 and placed between the fixed plate 55 and the slider 52.

[0033] In the above embodiment, preferably, the pushing mechanism 5 also includes a limit block 1 58 and a limit block 2 59, the limit block 1 58 is fixed on the mounting base 3, and the limit block 2 59 is fixed on the pushing block 51. The reset distance of the pushing block 51 is limited by the cooperation of the limit block 1 58 and the limit block 2 59, so that the position of the pushing block 51 in the initial stage each time remains consistent, which is convenient for subsequent detection of the detection needle 8.

[0034] A detection cylinder 7 and a detection needle 8 fixedly connected to the telescopic end of the detection cylinder 7 are also fixed on the mounting seat 3. When the pushing block 51 is in the initial stage, the detection needle 8 is located directly above the material through hole 53, and the diameter of the detection needle 8 is smaller than the inner diameter of the material through hole 53; specifically, when the pushing block 51 and the receiving block 61 are in the resetting stage, the receiving block 61 has returned to the initial position, and the receiving hole 62 is aligned with the material through hole 53, after the product falls into the receiving hole 62 from the material through hole 53, the detection cylinder 7 drives the detection needle 8 to move downward and penetrate into the material through hole 53 to detect whether it is in place. If not, the machine will be shut down and the staff will clear the fault in time; if in place, the workbench 1 will continue to drive the receiving block 61 to move toward the center of the machine tool chuck 2.

[0035] Please see attached Figure 3 As shown, the material receiving mechanism 6 also includes a carrier plate 64, an ejection cylinder 65 fixed on the carrier plate 64 and a push rod 66 connected to the telescopic end of the ejection cylinder 65. The material receiving block 61 is fixed on the carrier plate 64, and the carrier plate 64 is fixed on the workbench 1. When the workbench 1 moves, it drives the material receiving block 61 and the ejection cylinder 65 to move together. One end of the push rod 66 passes through the material receiving block 61 and extends into the material receiving hole 62. When the workbench 1 drives the material receiving block 61 to move to align and contact with the machine tool chuck 2, the ejection cylinder 65 drives the push rod 66 to move to eject the product in the material receiving hole 62 from the discharge port 63 and send it to the machine tool chuck 2. The machine tool chuck 2 clamps the product and starts to execute the processing program.

[0036] In the above embodiments, preferably, please refer to the attached Figure 4 As shown, the material discharge channel 4 is fixed on the mounting base 3 by means of a plurality of support plates (not shown), and a notch 41 is provided on the surface of the material discharge channel 4 along its length direction. If there is a blockage or jam in the material discharge channel 4, it can be observed in time through the notch 41, and the notch also facilitates the staff to clear the jam.

[0037] In the above embodiment, the automatic loading device of the CNC lathe preferably also includes a product recovery tube 9, which is fixed on the surface of the workbench 1, and a recovery port 91 is provided on the side of the product recovery tube 9 facing the machine tool chuck 2. After the processing is completed, the chuck is loosened, the product is ejected, and falls into the product recovery tube 9.

[0038] Specific working process:

[0039] First, the workbench 1 drives the receiving block 61 to move from under the pushing block 51 and abut against the slider 52. At this time, the upper surface of the receiving block 61 is placed under the material through hole 53 to block the bottom material through hole 53. The workbench 1 drives the receiving block 61 to continue to move and pushes the slider 52 to move along the slide rail 56 to move the speed return spring 54 until the material through hole 53 is aligned with the bottom end outlet of the unloading channel 4. The product falls from the unloading channel 4 into the material through hole 53. Under the action of the receiving block 61, the product remains in the material hole.

[0040] Then, the workbench 1 drives the receiving block 61 to move in the opposite direction, and the receiving block 61 and the slider 52 move with the receiving block under the action of the return spring 54, and the plane of the receiving block 61 is used to block the next product discharge in the unloading channel 4, until the limit block 1 58 abuts against the limit block 2 59, and the receiving block 61 and the slider 52 return to the initial position and stop moving, and then the receiving block 61 continues to move relative to the pushing block 51 until the receiving hole 62 is aligned with the material through hole 53, and the product falls from the material through hole 53 into the receiving hole 62;

[0041] The workbench 1 drives the receiving block 61 to continue to move toward the machine chuck 2. The workbench 1 moves forward so that the discharge hole on the receiving block 61 is close to and aligned with the machine chuck 2. The ejection cylinder 65 drives the ejector rod 66 to move and eject the product in the receiving hole 62 from the discharge port 63 to the machine chuck 2. The machine chuck 2 clamps the product, and the workbench 1 retracts to start the processing program.

[0042] After the processing is completed, the workbench 1 drives the product recovery tube 9 to move, so that the recovery port 91 of the product recovery tube 9 is aligned with the center of the machine tool chuck 2 and close to it, the machine tool chuck 2 is loosened, the product is ejected, and falls into the product recovery tube 9, and the product slides through the recovery tube to the product recovery box. This process is the loading process of processing a product, and then the above loading process is repeated. This solution has a simple structure and a fast loading speed. It can realize automatic loading, automatic product recovery, and realize the automation of the production process, so as to ensure production quality, improve production efficiency, and save production costs.
