Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 - 7 , the present invention provides a technical solution:

[0025] An automatic tightening device includes a bottom plate 1. A support column 2 is installed on the top of the bottom plate 1. A first disc 5 is installed on the outer wall of the upper end of the support column 2. A second motor 21 is installed at the inner bottom of the support column 2. The output end of the second motor 21 is installed with a second disc 6 through a coupling. The bottom of the second disc 6 is in close contact with the top of the first disc 5. A number of circular grooves 17 are evenly formed on the top of the second disc 6. A second part 22 is inserted and connected to the inner walls of a number of circular grooves 17. An installation frame 7 is installed on the top of the bottom plate 1. A cylinder 12 is installed on the top of the installation frame 7. The output end of the cylinder 12 penetrates through the top of the installation frame 7, and a T-shaped plate 13 is installed at the output end of the cylinder 12. A first motor 14 is installed at the bottom right end of the T-shaped plate 13. A tightening device 15 is installed at the output end of the first motor 14. The tightening device 15 is located directly above the circular grooves 17. A first feeding pipe 10 is installed at the left end of the top of the installation frame 7. A groove 32 is formed on the outer wall of the lower end of the first feeding pipe 10. A number of first parts 16 are evenly placed inside the first feeding pipe 10. A rectangular plate 31 is installed on the side wall of the left end of the installation frame 7. A blanking assembly 23 is installed between the rectangular plate 31 and the first feeding pipe 10. An installation plate 9 is installed on the rear side wall of the installation frame 7. A second feeding pipe 11 is installed on the top of the installation plate 9. The second feeding pipe 11 penetrates through the installation plate 9, and the bottom of the second feeding pipe 11 is in close contact with the top of the second disc 6. The discharge port of the second feeding pipe 11 is aligned with the circular grooves 17. A number of second parts 22 are evenly placed inside the second feeding pipe 11. A discharge pipe 18 is installed at the bottom of the first disc 5. The discharge pipe 18 is communicated with a group of circular grooves 17. A control device 8 is installed on the outer wall of the left end of the installation frame 7. The control device 8 is electrically connected to the first motor 14, the second motor 21 and the blanking assembly 23 respectively.

[0026] Further, the blanking assembly 23 includes a third motor 231. The third motor 231 is fixedly connected to the rear outer wall of the rectangular plate 31. The output end of the third motor 231 penetrates through the rectangular plate 31, and a gear 232 is fixedly installed at the output end of the third motor 231. A first rack 233 and a second rack 234 are respectively slidably connected to the front outer wall of the rectangular plate 31. The first rack 233 is located below the second rack 234, and both the first rack 233 and the second rack 234 are meshed with the gear 232.

[0027] Further, a second baffle 236 is installed at the right end of the first rack 233. The top of the second baffle 236 is in close contact with the bottom of the first feeding pipe 10. A first baffle 235 is installed at the right end of the second rack 234. The first baffle 235 is in close contact with the inner wall of the groove 32. The third motor 231 is electrically connected to the control device 8. When the circular groove 17 rotates to directly below the first feeding pipe 10, the control device 8 controls the third motor 231 to rotate. The output end of the third motor 231 drives the first rack 233 to move leftward through the gear 232. The first rack 233 drives the second baffle 236 away from the bottom of the first feeding pipe 10, causing the first part 16 to automatically fall into the circular groove 17. At the same time, the gear 232 drives the second rack 234 to move rightward. The second rack 234 drives the first baffle 235 to insert into the groove 32, thus blocking the continuous fall of the upper first part 16. After the filled circular groove 17 moves away from below the first feeding pipe 10, the third motor 231 rotates in reverse. The first baffle 235 leaves the groove 32, and the second baffle 236 returns to the bottom of the first feeding pipe 10, causing the first part 16 to automatically fall onto the top of the second baffle 236, preparing for subsequent work.

[0028] Further, a round rod 19 is installed at the bottom of the rear end of the T-shaped plate 13. A convex block is installed at the bottom of the round rod 19. The convex block is located directly above the discharge pipe 18. The cylinder 12 drives the T-shaped plate 13 to move downward, causing the first motor 14 to tighten the first part 16 and the second part 22 through the tightening device 15. At the same time, the round rod 19 pushes the tightened first part 16 and second part 22 inside the circular groove 17 into the discharge pipe 18 through the convex block, discharging the circular groove 17.

[0029] Further, a number of groups of heat dissipation holes 20 are evenly formed in the outer wall of the support column 2. A side door 3 is installed on the outer wall of the support column 2 through a number of hinge combinations 4. A handle 30 is installed on the outer wall of the side door 3. Pulling the handle 30 outward can open the side door 3, thus facilitating the maintenance of the parts inside the support column 2.

[0030] Further, a second rectangular block 25 is installed on the outer wall of the side door 3. A first rectangular block 24 is installed on the outer wall of the support column 2 close to the side door 3. Limiting holes 26 are formed in the side walls of both the first rectangular block 24 and the second rectangular block 25.

[0031] Further, a limiting rod 27 is inserted and connected to the inner wall of the limiting hole 26. A handle 28 is installed at the end of the limiting rod 27 close to the first rectangular block 24. A spring 29 is installed between the handle 28 and the first rectangular block 24. The spring 29 is sleeved outside the limiting rod 27. Pulling the handle 28 causes the limiting rod 27 to leave the limiting hole 26 inside the second rectangular block 25, thus facilitating the opening of the side door 3.

[0032] Working principle: The control device 8 controls the second motor 21 to drive the second disc 6 to rotate. When a certain set of circular grooves 17 on the second disc 6 moves to the bottom of the second material conveying pipe 11, the parts 22 inside the second material conveying pipe 11 automatically fall into the circular grooves 17. When the circular groove 17 containing the parts 22 moves below the first material conveying pipe 10, the control device 8 controls the blanking assembly 23 to cooperate with the first material conveying pipe 10 to send the first part 16 to the upper end of the parts 22. When the second disc 6 is about to rotate, the control device 8 controls the blanking assembly 23 to block the discharge port at the bottom of the first material conveying pipe 10. When the circular groove 17 containing the parts 22 and the first part 16 moves directly below the first motor 14, the output end of the cylinder 12 pushes the T-shaped plate 13 to move downward. The T-shaped plate 13 drives the tightening device 15 to move above the first part 16 through the first motor 14 and tightens the first part 16 and the parts 22 together. Then, the output end of the cylinder 12 drives the first motor 14 to retract through the T-shaped plate 13. Finally, the second disc 6 moves the tightened first part 16 and parts 22 to the discharge pipe 18, thereby discharging the circular groove 17 to achieve automatic blanking.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
