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.

[0030] Referring to Figures 1 to 6, the present invention provides an automatic loading and unloading mechanism for a five-axis CNC gear shaving machine: including a machine body 1 and a working chamber 3. A control plate 2 is installed on the outer wall of the machine body 1 via a rotating frame. The working chamber 3 is located inside the machine body 1. An electric clamp 4 is installed on the inner wall of the top of the working chamber 3 via a lifting device. A drive motor 5 is installed on the inner wall of the working chamber 3 via a rotating device. A drive rod 6 is fixedly installed at the output end of the drive motor 5. A gear shaving cutter 7 is fixedly installed at the top end of the drive rod 6. A first servo motor 8 is fixedly installed on the inner wall of the top of the working chamber 3. A first screw 9 is fixedly installed at the output end of the first servo motor 8. A limit rod 10 is fixedly installed on the inner wall of the top of the working chamber 3. A lifting plate 11 is sleeved on the outer surface of the first screw 9. The upper surface of the lifting plate 11 is threadedly connected to the first screw 9. The upper surface of the lifting plate 11 is inserted into the limit rod 10. A first electric push rod 12 is fixedly installed on the upper surface of the lifting plate 11. A loading tray 13 is fixedly installed at the output end of the first electric push rod 12.

[0031] To automatically unload the processed gears, a second electric actuator 14 is fixedly installed at the bottom of the working chamber 3. A movable plate 15 is fixedly installed at the output end of the second electric actuator 14. A second servo motor 16 is fixedly installed on the side of the movable plate 15 away from the second electric actuator 14. A rotating rod 17 is fixedly installed at the output end of the second servo motor 16. A unloading frame 18 is fixedly installed at the end of the rotating rod 17 away from the second servo motor 16. A fixed plate 19 is fixedly installed on the inner wall of the top of the working chamber 3. A sliding rod 20 is fixedly installed on one side wall of the fixed plate 19. The side wall of the movable plate 15 is inserted into the sliding rod 20. A positioning frame 21 is fixedly installed at the bottom of the working chamber 3. A loading box 22 is slidably connected to the inner wall of the positioning frame 21.

[0032] By setting up a machine body 1, control board 2, working chamber 3, electric chuck 4, drive motor 5, drive rod 6, shaving cutter 7, servo motor 8, screw 9, limit rod 10, lifting plate 11, electric push rod 12, loading plate 13, electric push rod 14, movable plate 15, servo motor 16, rotating rod 17, unloading frame 18, fixing plate 19, sliding rod 20, positioning frame 21, and loading box 22, the automatic loading and unloading function of gears is realized. By setting an automatic loading and unloading mechanism inside the working chamber 3 of the gear shaving machine, the operator only needs to place the gear on the loading plate 13, saving the operator's time and effort, speeding up the gear processing rate, improving the practicality of the CNC gear shaving machine, and at the same time avoiding injury to the operator, thus improving the safety of the CNC gear shaving machine.

[0033] The upper surface of the feeding tray 13 is provided with a positioning component, which includes a groove 23 and a second screw 24. The groove 23 is formed on the upper surface of the feeding tray 13. The second screw 24 is rotatably connected to the inner wall of the groove 23. The second screw 24 passes through the inner wall of the groove 23 and extends to the outside of the feeding tray 13. A rotating block 25 is fixedly installed at the end of the second screw 24 away from the feeding tray 13. Two positioning blocks 26 are symmetrically arranged on the upper surface of the feeding tray 13. A driving block 27 is fixedly installed on the lower surface of the positioning block 26. The outer surface of the second screw 24 is provided with a forward thread and a reverse thread. The side walls of the two driving blocks 27 are respectively provided with threaded holes that mesh with the forward thread and the reverse thread. A limiting block 28 is fixedly installed on the side wall of the driving block 27. A limiting groove is formed on the inner wall of the groove 23. The limiting block 28 is slidably connected to the inner wall of the limiting groove.

[0034] By setting groove 23, screw 24, rotating block 25, positioning block 26, driving block 27 and limiting block 28, the distance between the two positioning blocks 26 can be adjusted. By adjusting the distance between the two positioning blocks 26, gears of different specifications can be positioned, making it easier to load and unload gears. On the original basis, the practicality of CNC gear shaving machine is further improved.

[0035] Working principle: Before using the CNC gear shaving machine to process the gear, the operator first adjusts the positioning component according to the specifications of the gear to be processed. First, place the gear to be processed on the upper surface of the loading plate 13, and then rotate the rotating block 25 so that the rotating block 25 drives the second screw 24 to rotate inside the groove 23. When the second screw 24 rotates, it drives the driving block 27 to move. Under the action of the limit block 28, the two driving blocks 27 drive the two positioning blocks 26 to move away from each other or move closer to each other. When the gear can just fit onto the outer surface of the two positioning blocks 26, stop rotating the rotating block 25 to complete the adjustment.

[0036] When machining gears using a CNC gear shaving machine, the operator places the gear on the upper surface of the loading tray 13. The first servo motor 8 then runs, driving the first screw 9 to rotate. Under the action of the limit rod 10, the lifting plate 11 drives the first electric push rod 12 upwards. Simultaneously, the first electric push rod 12 extends, pushing the loading tray 13 closer to the electric chuck 4. When the gear is directly below the electric chuck 4, the first electric push rod 12 stops extending. Then, the loading tray 13 drives the gear to continue rising. When the gear enters the electric chuck 4, the electric chuck 4 clamps the gear. Then, the first servo motor 8 and the first electric push rod 12 run in opposite directions, causing the loading tray 13 to return to its original position. The electric chuck 4 then drives the gear downwards via the lifting device, while simultaneously driving the drive motor 5, which in turn drives the shaving cutter 7 to rotate via the drive rod 6. When the shaving cutter 7 contacts the gear, it processes the gear. The tilt angle of the shaving cutter 7 can also be adjusted via the rotating device.

[0037] After the gear is processed, the electric chuck 4 lifts the gear via a lifting device. Then, the second electric push rod 14 moves, pushing the movable plate 15 to slide on the outer surface of the slide rod 20. At the same time, it drives the second servo motor 16 and the unloading frame 18 to move towards the electric chuck 4. When the unloading frame 18 is directly below the electric chuck 4, the electric chuck 4 releases the gear, causing it to fall into the unloading frame 18. Then, the second electric push rod 14 shortens. When the opening of the unloading frame 18 is directly above the loading box 22, the second servo motor 16 runs, driving the unloading frame 18 to rotate via the rotating rod 17. This causes the unloading frame 18 to rotate towards the opening, tilting it. The gear slides from the unloading frame 18 into the loading box 22. Then, the second servo motor 16 rotates back, causing the unloading frame 18 to return to its original position, completing the unloading process.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
