[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1:

[0029] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A cylindrical hinge chamfering processing device includes a machine body 10. A loading platform 11 is rotatably arranged on the end face of the machine body 10. Multiple loading slots 12 are arranged on the end face of the loading platform 11. A feeding pusher 13 for pushing the hinge is slidably arranged inside the multiple loading slots 12. A dust collection chamber 23 is arranged on one side of the loading platform 11. A mounting plate 24 is arranged on the end face of the dust collection chamber 23. A chamfering tool 22 is arranged on the end face of the mounting plate 24. A positioning block 20 is arranged on one side of the chamfering tool 22 on the end face of the mounting plate 24. Multiple positioning slots 21 are arranged on the end face of the positioning block 20. The positioning slots 21 are used to position the hinge. The corners of the multiple positioning blocks 20 and the positioning slots 21 are all arc-shaped. A drive plate 29 for rotating the hinge is slidably arranged above the positioning slots 21.

[0030] In this design, the feeding pusher 13 is semi-circular in shape and slides inside the loading groove 12. This pusher pusher 13 can push the hinge inside the loading groove 12, causing the protruding end of the hinge to abut against the inclined surface of the chamfering tool 22, thus achieving the feeding effect. The chamfering tool 22 is triangular prism in shape, and multiple machining heads are provided on its inclined surface. These machining heads abut against the outer edge of the protruding end of the cylindrical hinge, performing chamfering on the outer edge of the cylindrical hinge. The positioning block 20 and the positioning groove 2... The connection point of 1 is set in an arc shape, which makes it easier to push the protruding end of the hinge into the positioning groove 21 to complete the positioning when the hinge is pushed inside the loading groove 12. This prevents the protruding end from getting stuck at the corner of the positioning groove 21 and the positioning block 20, so that the device can load materials normally and improve the stability of the equipment. The bottom end face of the drive plate 29 has multiple vertical grooves, which increases the contact area between the drive plate 29 and the outer circular surface of the hinge, thereby making it easier to drive the hinge to rotate and improve the processing quality.

[0031] refer to Figure 5 and Figure 6 Each of the multiple loading slots 12 has a feeding pusher 13 inside. A connecting rod 14 is slidably arranged inside the through slot 15. The connecting rod 14 is fixedly connected to the feeding pusher 13. A through slot connection slot 151 is provided on one side of the loading slot 12. A threaded sleeve 17 is provided at one end of the connecting rod 14 extending along the through slot connection slot 151. A threaded rod 18 is rotatably arranged inside the threaded sleeve 17. The threaded sleeve 17 and the threaded rod 18 are connected by a threaded drive.

[0032] In this scheme, multiple feeding push blocks 13 are connected to a connecting rod 14. When the threaded sleeve 17 slides outside the threaded rod 18, it will drive the connecting rod 14, so that the connecting rod 14 will drive multiple feeding push blocks 13 at the same time, thereby enabling multiple feeding push blocks 13 to push the hinge to complete the feeding, thereby improving the feeding efficiency. The upper end face of the feeding push block 13 is provided with rounded corners. This setting allows the hinge to slide into the loading slot 12 through the rounded corners when feeding, improving the feeding quality. A micro motor 19 is provided on one side of the loading table 11, and the output end of the micro motor 19 is fixedly connected to the threaded rod 18.

[0033] refer to Figure 2 and Figure 3 The loading platform 11 is equipped with a rotating rod 45. One end of the rotating rod 45 extends along the machine body 10 and is equipped with a third motor 48. The output end of the third motor 48 is fixedly connected to the rotating rod 45. A discharge box 44 is provided below the loading platform 11.

[0034] In this design, the rotating rod 45 is fixedly connected to the loading table 11, and the rotating rod 45 is rotatably connected to the inside of the end face of the machine body 10. It extends from the outer wall of the machine body 10 and connects to the output end of the third motor 48. By setting the rotating rod 45, after the chamfering is completed, the loading table 11 can be rotated so that the hinge on the end face of the loading table 11 falls into the discharge box 44 at the bottom by gravity, thus completing the discharge and facilitating the next use, thereby improving the processing efficiency.

[0035] refer to Figure 1 , Figure 2 , Figure 3 and Figure 8 Both sides of the inner wall of the body 10 are provided with first slide rails 27. The outer surfaces of the two first slide rails 27 are slidably provided with first electric sliders 26. A support plate 25 is slidably provided between the two first electric sliders 26. The support plate 25 is slidably connected to the drive plate 29. The support plate 25 is provided with a limiting groove 40 inside. A limiting slider 41 is slidably provided inside the limiting groove 40. A fixing plate 28 is provided at the bottom of the limiting slider 41. The fixing plate 28 is fixedly connected to the drive plate 29. A connector 30 is provided at the top of the fixing plate 28. A drive cylinder 31 is provided at one end of the connector 30. The output end of the drive cylinder 31 is fixedly connected to the connector 30.

[0036] In this design, the first electric slider 26 and the first slide rail 27 are used to lift the drive plate 29, allowing the feeding pusher 13 to smoothly enter the positioning groove 21 when pushing the hinge to slide, preventing it from being blocked by the drive plate 29. This ensures the device can operate normally and improves the overall stability of the device. The length of the limiting slide groove 40 is greater than the length of the limiting slider 41, allowing the limiting slider 41 to slide inside the limiting slide groove 40. The drive cylinder 31 is existing technology and its main function is to drive the connecting member 30 to reciprocate, thereby causing the connecting member 30 to drive the bottom drive plate 29 to reciprocate. During the sliding process, the drive plate 29 continuously rubs the bottom hinge to rotate, thereby rotating the hinge to achieve the chamfering effect.

[0037] refer to Figure 1 , Figure 2 and Figure 3 An air duct 32 is provided on the top of the support plate 25, and multiple gas nozzles 33 are provided on one side of the air duct 32. An air pump 46 is provided inside the machine body 10 below the air duct 32. The air duct 32 and the air pump 46 are connected by a hose. A slag discharge port 16 is provided between the positioning block 20 and the chamfering tool 22. The slag discharge port 16 is connected to the dust collection chamber 23.

[0038] In this design, the air passage 32 is hollow inside; multiple air passages 32 point towards the inclined surface of the chamfering tool 22. This arrangement allows for air blowing to clean the end face of the chamfering tool 22 during hinge machining, blowing the debris opposite the chamfering tool 22 into the interior of the slag discharge port 16, and then into the interior of the dust collection chamber 23 through the slag discharge port 16 for debris collection and treatment, which can effectively improve machining quality.

[0039] refer to Figure 2 , Figure 3 Figure 5 and Figure 7 A protective shell 35 is slidably disposed above the loading platform 11. A feeding chamber 34 is disposed on the top of the protective shell 35. A feeding wheel 36 is rotatably disposed inside the protective shell 35. Multiple feeding slots 37 are disposed inside the feeding wheel 36. A baffle 38 is disposed on the outer surface of the feeding wheel 36. Multiple baffle grooves 39 are disposed on the outer surface of the baffle 38. A second slide rail 42 is disposed on the inner wall of the machine body 10. A second slider 43 is slidably disposed on the end face of the second slide rail 42. The second slider 43 is fixedly connected to the outer surface of the protective shell 35.

[0040] In this design, the feeding chamber 34 is funnel-shaped and is used to load the hinges to be processed. The protective shell 35 is annular, with a discharge port on the bottom circular surface and a feed port on the top circular surface. The inside of the feeding chamber 34 is connected to the protective shell 35 through the feed port. The baffle 38 can prevent the hinges from sliding out of the feeding slot 37. The baffle 39 is used to support the protruding end of the hinge and prevent the hinge from tilting inside the feeding slot 37, thus playing a guiding role and improving the stability of feeding. A second motor 47 is provided on one side of the protective shell 35, and the output shaft of the second motor 47 is fixedly connected to the feeding wheel 36.

[0041] In use, the hinge to be processed is placed into the feeding chamber 34. The hinge enters the feeding slot 37 through the feeding port of the feeding chamber 34 and the protective shell 35. Then, the second motor 47 is started, which drives the feeding wheel 36 to rotate. The rotation of the feeding wheel 36 drives the feeding slot 37 to rotate. At this time, the other feeding slots 37 rotate successively to the bottom of the feeding port of the protective shell 35, so that the hinges inside the feeding chamber 34 continuously enter the feeding slots 37 to be loaded. When the feeding wheel 36 rotates, it drives... The hinge inside the feeding slot 37 rotates until the feeding slot 37 rotates above the loading slot 12. At this time, the hinge inside the feeding slot 37 falls into the loading slot 12 due to gravity. At the same time, the second slider 43 is activated, so that the second slider 43 slides at a constant speed on the surface of the second slide rail 42. The second slider 43 drives the protective shell 35 to move, and the protective shell 35 drives the internal feeding wheel 36 to move. The feeding wheel 36 moves while rotating, tilting the hinge inside the feeding slot 37 into each loading slot 12.

[0042] Then, the micro motor 19 is started, which drives the threaded rod 18 to rotate. After the threaded rod 18 rotates, it drives the threaded sleeve 17 to move. The threaded sleeve 17 drives one end of the connecting rod 14 to move, which in turn drives the top feeding push block 13 to move. The feeding push block 13 slides along the through groove 15. When the feeding push block 13 moves, it pushes the hinge inside the loading groove 12, and the protruding end of the hinge abuts against the inclined surface of the chamfering tool 22 to complete the feeding.

[0043] Then, the first electric slider 26 is activated, causing it to slide downward along the first slide rail 27. This causes the support plate 25 between the two first electric sliders 26 to slide downward. As the support plate 25 slides downward, it drives the bottom fixed plate 28 to move. When the drive plate 29 at the bottom of the fixed plate 28 contacts the outer surface of the hinge, it stops moving. Then, the drive cylinder 31 is activated, causing the output end of the drive cylinder 31 to continuously push the connector 30 back and forth. This causes the connector 30 to drive the fixed plate 28 to slide back and forth. Then, the drive plate 29 slides back and forth behind the fixed plate 28 and continuously rubs the bottom hinge, causing the hinge to rotate. This causes the protruding end of the hinge to continuously rub against the chamfering tool 22 to form a chamfer.

[0044] During hinge processing, the air pump 46 is started. The air pump 46 delivers gas into the air passage 32 through a hose and blows it out through the gas nozzle 33. The gas nozzle 33 slides down with the support plate 25, so that the gas nozzle 33 blows air out onto the protruding end of the hinge, blowing off the debris generated by the chamfering tool 22 and dropping it into the dust collection chamber 23 through the slag discharge port 16 for collection.

[0045] After the final processing is completed, the third motor 48 is started, which drives the rotating rod 45 to rotate. The rotating rod 45 drives the loading platform 11 to rotate. The hinge on the end face of the loading platform 11 loses its support and slides down into the discharge box 44 at the bottom by gravity, thus completing the unloading.
