[0023] Install the automatic feeding device 1 on one side of the CNC milling machine 3, and realize the automatic feeding of parts through the sliding component and the feeding component. During the feeding operation, control the movement of the installation slide plate 12 on the installation cross beam 13, so that the installation bottom plate 11 moves synchronously with the installation slide plate 12. When the installation bottom plate 11 moves to the set position outside the CNC milling machine 3, at this time, the installation bottom plate 11 is at the top of the automatic feeding device 4. Furthermore, by controlling the operation of the feeding driving part 15, the feeding driving part 15 drives the installation bottom plate 11 to descend until the suction cup 14 adsorbs the parts on the automatic feeding device 4. Subsequently, the feeding driving part 15 drives the installation bottom plate 11 to return to its position, and at the same time, control the installation slide plate 12 to move along the installation cross beam 13 to drive the installation bottom plate 11 into the CNC milling machine 3 and make the installation bottom plate 11 located above the part clamping device 5 inside the CNC milling machine 3. At this time, the feeding driving part 15 drives the installation bottom plate 11 to descend again, so that the suction cup 14 drives the parts to move towards the part clamping device 5 and finally places the parts on the part clamping device 5, enabling the part clamping device 5 to clamp and fix the parts, so as to facilitate the CNC milling machine 3 to perform processing operations on the clamped parts, thereby realizing the unmanned feeding operation of parts and improving the feeding efficiency of parts.

[0024] After the CNC milling machine 3 completes the processing operation on the parts, the feeding driving part 15 drives the installation bottom plate 11 to descend, so that the suction cup 14 adsorbs the parts on the part clamping device 5. Subsequently, the feeding driving part 15 drives the installation bottom plate 11 to rise, and the installation slide plate 12 drives the installation bottom plate 11 to slide along the installation cross beam 13 to transfer the processed parts out of the CNC milling machine 3, facilitating the next automatic feeding operation of the automatic feeding device 1.

[0025] In the above embodiment, the feeding driving part 15 adopts a cylinder to drive the installation bottom plate 11 to lift and lower relative to the installation slide plate 12 under the expansion and contraction of the cylinder, so as to facilitate the suction cup 14 to adsorb parts for transfer operations. Since the number of suction cups 14 is at least two, at least two parts can be adsorbed by the suction cups 14 and at least two parts can be placed on the part clamping device 5 for clamping and fixing during one feeding operation, so that the CNC milling machine 3 can perform processing operations on at least two parts at one time, improving the processing efficiency of parts.

Connecting pieces are arranged on both sides of the installation slide plate 12. The motor 16 is fixed at one end of the cross beam and is connected to the lead screw.

Both ends of the lead screw are rotatably connected to the crossbeam, and the middle position of the mounting slide plate 12 is threadedly connected to the lead screw, so that the lead screw can be driven to rotate by the motor 16, and the rotating lead screw drives the mounting slide plate 12 to move smoothly along the mounting crossbeam 13, thereby realizing the adjustment of the position of the mounting slide plate 12, so that the mounting base plate 11 follows the mounting slide plate 12 to move synchronously, facilitating the transfer operation of parts, and facilitating the realization of automatic loading and unloading of parts.

[0028] In an embodiment of the present invention, a sleeve 17 and a connecting sleeve 18 are provided at the bottom of the mounting slide plate 12. A notch is provided around the sleeve 17. The output end of the loading driving member 15 is inserted and connected to the sleeve 17. The connecting sleeve 18 is threadedly connected to the sleeve 17 to squeeze the sleeve 17 to clamp the loading driving member 15 under the action of the notch, so that the output shaft of the loading driving member 15 is fixed on the mounting slide plate 12 through the sleeve 17 and the connecting sleeve 18. Since the loading driving member 15 is mounted on the mounting base plate 11, when the loading slide plate moves along the mounting slide rail, the mounting base plate 11 can be driven to move synchronously by the loading driving member 15. At the same time, under the telescopic action of the loading driving member 15, the mounting base plate 11 can be driven to lift relative to the mounting slide plate 12, so as to facilitate the suction cup 14 to adsorb parts for transfer operation.

[0029] In an embodiment of the present invention, at least two guide posts 19 are fixed on the mounting base plate 11. At least two of the guide posts 19 are located around the loading driving member 15, and at least two of the guide posts 19 pass through the mounting slide plate 12 and are slidably connected to the mounting slide plate 12, so as to provide accurate guidance for the mounting base plate 11 under the action of the guide posts 19, and make the mounting base plate 11 move smoothly along the guide posts 19 to improve the loading accuracy.

Then, under the movement of the mounting base plate 11, the suction cup 14 drives the parts to displace, thereby realizing the automatic loading of parts. Among them, the external air source adopts an air pump to control the suction cup 14 to inhale air when the air pump works, so that the suction cup 14 adsorbs parts through negative pressure operation.

[0032] In an embodiment of the present utility model, the loading component further includes a shock-absorbing spring 21, and the shock-absorbing spring 21 is disposed between the air delivery pipe 20 and the suction cup 14, so as to provide additional support and buffering for the air delivery pipe 20 under the action of the shock-absorbing spring 21, and reduce the air source loss caused by vibration.

[0033] In an embodiment of the present utility model, one end of the air delivery pipe 20 connected to the suction cup 14 is provided with a thread, a sealing platform 22 and a sealing ring.

The sealing ring is fixedly attached to the sealing platform 22, and the end face of the suction cup 14 is attached to the sealing ring to increase the airtightness after the suction cup 14 is threadedly connected to the air delivery pipe 20 and avoid air leakage, which may cause the suction cup 14 to be unable to adsorb parts.
