[0036] An outer positioning mechanism 101 is arranged to cooperate with the feeding telescopic rod 1 to retract and position the outer wall of the annular body 8, and the outer positioning mechanism 101 is installed on the main frame body 2.

[0037] The inner positioning mechanism 404 is used to cooperate with the outer positioning mechanism 101 to position the inner wall of the ring body 8. The inner positioning mechanism 404 is installed on the outer positioning mechanism 101;

[0038] The driving mechanism 202 is used to cooperate with the retraction of the feeding telescopic rod 1 to clamp the outer wall of the annular body 8 and drive the annular body 8 to rotate itself to complete the polishing. The driving mechanism 202 is installed on the main frame 2;

[0039] And two control mechanisms 303 are used to load the new annular body 8 when the loading telescopic rod 1 is extended and to automatically unload the polished annular body 8 synchronously, so that when the loading telescopic rod 1 is retracted, it can drive the outer positioning mechanism 101 and the driving mechanism 202 to automatically clamp and polish the annular body 8.

[0040] Among them, the two control mechanisms 303 include a limit plate 10, a connecting rod 11, a connecting rod 2 12, a circular gear groove 3, a third shaft rod 30 and a one-way gear 45. The connecting rod 11 is fixedly connected to the push plate 13, and the connecting rod 2 12 is slidably connected to the connecting rod 11 through the set sliding groove and slider. The bottom of the connecting rod 2 12 is fixedly connected with the third shaft rod 30, and the end of the third shaft rod 30 away from the connecting rod 2 12 is rotationally connected to the one-way gear 45 through a one-way bearing. The circular gear groove 3 is fixedly connected to the main frame 2, and the one-way gear 45 is meshed with the inner wall of the circular gear groove 3. The end of the connecting rod 2 12 is fixedly connected to the limit plate 10. There are two of the two control mechanisms 303, and the two control mechanisms 303 are symmetrically distributed.

[0041] In this embodiment, when in use, the annular body 8 is placed in the storage bin 4. In the initial state, the loading telescopic rod 1 is in a retracted state, and several annular bodies 8 are neatly stacked in the storage bin 4. Then the loading telescopic rod 1 starts loading, so that the push plate 13 pushes the lowest annular body 8 to move. Since the one-way gear 45 and the third shaft 30 are connected by a one-way bearing, when the loading telescopic rod 1 reciprocates, the one-way gear 45 will slide around the shape of the circular gear groove 3. When the loading telescopic rod 1 is extended, the one-way gear 45 slides along the side track of the circular gear groove 3 away from the storage bin 4. In this state, the limit plate 10 and the limit rod 9 are in a distant state, and will not affect the slider 25 and the slide rod 18.

[0042] Among them, the outer positioning mechanism 101 includes a fixed plate 17, a support spring 22, two L-shaped polishing heads 7, two mounting slides 16 and two slide rods 18. The fixed plate 17 is fixedly connected to the main frame 2, the two mounting slides 16 are both slidably connected to the fixed plate 17, the two slide rods 18 are respectively fixedly connected to the two mounting slides 16, the two L-shaped polishing heads 7 are both fixedly connected to the two mounting slides 16, the support spring 22 is fixedly connected between the two mounting slides 16, and two outer positioning mechanisms 101 are provided, and the two outer positioning mechanisms 101 are symmetrically distributed.

[0043] In this embodiment, when the feeding telescopic rod 1 and the push plate 13 move the ring body 8 to the designated processing position, that is, Figure 1 The middle ring body 8 is located, and then the feeding telescopic rod 1 is retracted. At this time, the two limit plates 10 move to the inner side of the circular gear groove 3 along with the connecting rod 2 12, the third shaft 30 and the one-way gear 45, that is, Figure 10 The position of the two slide rods 18 is inserted into the sliding groove opened by the limit plate 10. Then the feeding telescopic rod 1 is retracted and the slide rod 18 is restricted by the sliding groove opened on the limit plate 10, so that the two L-shaped polishing heads 7 are close to each other until they are close to the outer wall of the ring body 8.

[0044] Among them, the inner positioning mechanism 404 includes a circular mounting plate 15, a rectangular mounting groove 14, a slide rod 21, an internal spring 44 and a bevel rack rod 43. The slide rod 21 is slidingly connected to the inner wall of one of the L-shaped polishing heads 7. The internal spring 44 is fixedly connected between the L-shaped polishing head 7 and the slide rod 21. The bevel rack rod 43 is arranged below the slide rod 21. The circular mounting plate 15 is fixedly connected to the L-shaped polishing head 7. The bevel rack rod 43 is slidingly connected to the circular mounting plate 15. The rectangular mounting groove 14 is fixedly connected to the circular mounting plate 15.

[0045] Among them, the inner positioning mechanism 404 also includes gear four 20, gear three 41, a second shaft rod 42, two third shaft rods 30 and two connecting racks 40. The second shaft rod 42 is rotatably connected to the circular mounting plate 15. Gear four 20 and gear three 41 are respectively arranged on both sides of the circular mounting plate 15. Gear four 20 and gear three 41 are respectively fixedly connected to the two ends of the second shaft rod 42. Gear four 20 is meshed with the outer wall of the bevel rack rod 43. The outer wall of gear three 41 is meshed with the outer wall of the two connecting racks 40. The two connecting racks 40 are distributed in a circular array. The two side polishing rods 39 are respectively fixedly connected to the ends of the two connecting racks 40.

[0046] In this embodiment, if Figure 7-Figure 9As shown, the L-shaped polishing head 7 below drives the circular mounting plate 15 to move together, so that the side polishing rod 39 can be level with the inner wall of the ring body 8, and at the same time, the slide rod 21 is squeezed downward by the upper L-shaped polishing head 7, thereby contacting the inclined end of the bevel rack rod 43, pushing the bevel rack rod 43 to move close to the second shaft rod 42, thereby driving gear four 20 to rotate gear four 20 drives the second shaft rod 42 and gear three 41 to rotate, thereby driving the two connecting racks 40 to extend, and the two side polishing rods 39 contact the inner wall of the ring body 8, thereby completing the positioning of the all-round polishing assembly of the ring body 8.

[0047] The length of the rectangular installation groove 14 is set to be smaller than the diameter of the ring body 8 so that the ring body 8 will not be displaced when the rectangular installation groove 14 moves upward, thereby ensuring the accuracy of the position of the ring body 8.

[0048] Among them, the driving mechanism 202 includes two limit rods 19, two fixed plates 23, two return springs 24 and two sliders 25. The two limit rods 19 are respectively fixedly connected to the two limit plates 10, the two fixed plates 23 are both fixedly connected to the main frame 2, the two sliders 25 are both slidably connected to the fixed plates 23, and the two return springs 24 are respectively fixedly connected between the two sliders 25 and the fixed plates 23.

[0049] Among them, the driving mechanism 202 also includes an arc-shaped mounting frame 6, a motor frame 35, a driving motor 34, a gear 2 33, a rotating ring 19, an upper gear group 31 and a side gear group 32. The two ends of the arc-shaped mounting frame 6 are fixedly connected to the two sliders 25, the motor frame 35 is fixedly connected to the arc-shaped mounting frame 6, the driving motor 34 is fixedly connected to the motor frame 35, the gear 2 33 is fixedly connected to the output shaft of the driving motor 34, the rotating ring 19 is slidingly connected to the outer wall of the arc-shaped mounting frame 6, the upper gear group 31 is fixedly connected to the top outer wall of the rotating ring 19, the side gear group 32 is fixedly connected to the inner ring side wall of the rotating ring 19, and the gear 2 33 is meshed with the side gear group 32.

[0050] Among them, the driving mechanism 202 also includes a number of gears 29, a number of first shafts 28, a number of clamping seats 27 and a number of clamping heads 26. The first shaft 28 is rotatably connected to the arc-shaped mounting frame 6, the gear 29 is fixedly connected to the first shaft 28, the first shaft 28 is meshed with the outer wall of the gear 29, the clamping seat 27 is fixedly connected to the first shaft 28, and the clamping head 26 is slidably connected to the clamping seat 27.

[0051] Among them, the driving mechanism 202 is provided with two symmetrically distributed in the upper and lower parts, the inner wall of each clamping seat 27 is fixedly connected with a strong spring 36, and the inner wall of each clamping seat 27 is fixedly connected with several pull ropes 37. A section of each pull rope 37 away from the clamping seat 27 is fixedly connected to the suction cup 38, and the edge of each suction cup 38 is fixedly connected to the clamping head 26.

[0052] In this embodiment, if Figure 4-Figure 6 As shown, when the feeding telescopic rod 1 continues to move backward, the limit rod 1 9 collides with the slider 2 25. At this time, the ends of the upper and lower sliders 25 are located directly below and above the limit rod 1 9. The limit rod 1 9 drives the two sliders 25 and the arc-shaped mounting frame 6 to approach each other, so that the clamping head 26 squeezes the strong spring 36 and retracts into the clamping seat 27. The upper and lower clamping heads 26 clamp the annular body 8. At the same time, since the suction cup 38 contacts the surface of the annular body 8, when the clamping head 26 retracts, the clamping seat 27 is pulled, so that the suction cup 38 generates negative pressure on the annular body 8, thereby enhancing the clamping force.

[0053] Then, when the driving motor 34 is started, gear 2 33 drives the side gear set 32 ​​and the rotating ring 19 to rotate, and the rotating ring 19 drives several gears 1 29 to rotate through the upper gear set 31, so that the upper and lower clamping heads 26 drive the annular part body 8 to rotate for polishing. After polishing is completed, the loading telescopic rod 1 retracts to its original position and then extends to drive the next annular part body 8 to load again. At this time, the two L-shaped polishing heads 7 are subjected to the force of the support spring 22, so that the two L-shaped polishing heads 7 are separated, and the two sliders 25 are separated by the force of the reset spring 24, so that the new annular part body 8 pushes the previous annular part body 8 to move. When the new annular part body 8 moves to the specified position, the polished annular part body 8 slides down along the inclined surface of the main frame 2 due to the action of gravity and automatically unloads.

[0054] The specific working principle and usage method of the present invention are explained in detail below: When in use, the annular part body 8 is placed in the storage bin 4. In the initial state, the loading telescopic rod 1 is in a retracted state, and several annular part bodies 8 are neatly stacked in the storage bin 4. Then the loading telescopic rod 1 starts loading, so that the push plate 13 pushes the lowest annular part body 8 to move. Since the one-way gear 45 and the third shaft rod 30 are connected by a one-way bearing, when the loading telescopic rod 1 reciprocates, the one-way gear 45 will slide around the shape of the circular gear groove 3. When the loading telescopic rod 1 is extended, the one-way gear 45 slides along the side track of the circular gear groove 3 away from the storage bin 4. In this state, the limit plate 10 and the limit rod 9 are in a distant state, and neither will act on the slider 25 and the slide rod 18.

[0055] When the feeding telescopic rod 1 and the push plate 13 move the ring body 8 to the designated processing position, that is, Figure 1The middle ring body 8 is located, and then the feeding telescopic rod 1 is retracted. At this time, the two limit plates 10 move to the inner side of the circular gear groove 3 along with the connecting rod 2 12, the third shaft 30 and the one-way gear 45, that is, Figure 10 The position of the two slide rods 18 is inserted into the sliding groove opened by the limit plate 10. Then the feeding telescopic rod 1 is retracted and the slide rod 18 is restricted by the sliding groove opened on the limit plate 10, so that the two L-shaped polishing heads 7 are close to each other until they are close to the outer wall of the ring body 8.

[0056] like Figure 7-Figure 9 As shown, the L-shaped polishing head 7 below drives the circular mounting plate 15 to move together, so that the side polishing rod 39 can be level with the inner wall of the ring body 8, and at the same time, the slide rod 21 is squeezed downward by the upper L-shaped polishing head 7, thereby contacting the inclined end of the bevel rack rod 43, pushing the bevel rack rod 43 to move close to the second shaft rod 42, thereby driving gear four 20 to rotate gear four 20 drives the second shaft rod 42 and gear three 41 to rotate, thereby driving the two connecting racks 40 to extend, and the two side polishing rods 39 contact the inner wall of the ring body 8, thereby completing the positioning of the all-round polishing assembly of the ring body 8.

[0057] The length of the rectangular installation groove 14 is set to be smaller than the diameter of the ring body 8 so that the ring body 8 will not be displaced when the rectangular installation groove 14 moves upward, thereby ensuring the accuracy of the position of the ring body 8.

[0058] like Figure 4-Figure 6 As shown, when the feeding telescopic rod 1 continues to move backward, the limit rod 1 9 collides with the slider 2 25. At this time, the ends of the upper and lower sliders 25 are located directly below and above the limit rod 1 9. The limit rod 1 9 drives the two sliders 25 and the arc-shaped mounting frame 6 to approach each other, so that the clamping head 26 squeezes the strong spring 36 and retracts into the clamping seat 27. The upper and lower clamping heads 26 clamp the annular body 8. At the same time, since the suction cup 38 contacts the surface of the annular body 8, when the clamping head 26 retracts, the clamping seat 27 is pulled, so that the suction cup 38 generates negative pressure on the annular body 8, thereby enhancing the clamping force.

[0059] Then, when the driving motor 34 is started, gear 2 33 drives the side gear set 32 ​​and the rotating ring 19 to rotate, and the rotating ring 19 drives several gears 1 29 to rotate through the upper gear set 31, so that the upper and lower clamping heads 26 drive the annular part body 8 to rotate for polishing. After polishing is completed, the loading telescopic rod 1 retracts to its original position and then extends to drive the next annular part body 8 to load again. At this time, the two L-shaped polishing heads 7 are subjected to the force of the support spring 22, so that the two L-shaped polishing heads 7 are separated, and the two sliders 25 are separated by the force of the reset spring 24, so that the new annular part body 8 pushes the previous annular part body 8 to move. When the new annular part body 8 moves to the specified position, the polished annular part body 8 slides down along the inclined surface of the main frame 2 due to the action of gravity and automatically unloads.

[0060] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0061] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
