Description

Technical Field

[0001] The present invention relates to the technical field of surface polishing, and particularly to a surface polishing device for processing annular castings. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece to obtain a bright and flat surface.

[0003] A patent with the authorization announcement number CN113696095B discloses a loading and unloading device for processing annular parts, including a workbench, an arc-shaped guide rod, a conveying assembly, an arc-shaped stopper, a receiving rod, an annular sliding rod, a support block, and a fixing assembly.

[0004] However, there are still some deficiencies in the above-mentioned invention patent during actual use: it is recorded in the specification that "the annular part 9 first squeezes the second wedge block 32, the second wedge block 32 slides, the first spring 33 contracts, and the second wedge block 32 squeezes the inner wall of the annular part 9 to fix the annular part 9, and then processes the fixed annular part 9". By squeezing the inner wall of the annular part with the second wedge block to fix the annular part, the subsequent processing can only be carried out on the outer ring of the annular part. Due to the extrusion of the second wedge block on the inner ring, synchronous polishing of the inner and outer rings cannot be achieved, and it is necessary to manually place the annular parts on the magnetic chuck one by one, resulting in a reduction in work efficiency. Therefore, the above-mentioned problems are proposed to be solved. Summary of the Invention

[0018] 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.

[0019] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0020] Referring to Figures 1-10 , a surface polishing device for processing annular castings, including a main frame body 2. A storage bin 4 is fixedly connected to the outer wall of the top of the main frame body 2. A feeding telescopic rod 1 is arranged between the main frame body 2 and the storage bin 4. The feeding telescopic rod 1 is fixedly connected to the main frame body 2. The end of the feeding telescopic rod 1 is fixedly connected to a push plate 13. A first baffle 5 is fixedly connected to the outer wall of the push plate 13. A number of annular part bodies 8 are placed in the storage bin 4. It further includes: An outer positioning mechanism 101, used to cooperate with the retraction of the feeding telescopic rod 1 to position the outer wall of the annular part body 8. The outer positioning mechanism 101 is installed on the main frame body 2; An inner positioning mechanism 404, used to cooperate with the outer positioning mechanism 101 to position the inner wall of the annular part body 8. The inner positioning mechanism 404 is installed on the outer positioning mechanism 101; A driving mechanism 202, used to cooperate with the retraction of the feeding telescopic rod 1 to clamp the outer wall of the annular part body 8 and drive the annular part body 8 to rotate itself to complete polishing. The driving mechanism 202 is installed on the main frame body 2; And two control mechanisms 303, used to achieve the effect of feeding a new annular part body 8 when the feeding telescopic rod 1 extends and automatically discharging the polished annular part body 8 synchronously, so that when the feeding telescopic rod 1 retracts, it can drive the outer positioning mechanism 101 and the driving mechanism 202 to automatically clamp and polish the annular part body 8.

[0021] Among them, the two control mechanisms 303 include a first limiting plate 10, a first connecting rod 11, a second connecting rod 12, a circular gear groove 3, a third shaft rod 30 and a one-way gear 45. The first connecting rod 11 is fixedly connected to the push plate 13. The second connecting rod 12 is slidably connected to the first connecting rod 11 through a set chute and slider. The bottom of the second connecting rod 12 is fixedly connected to the third shaft rod 30. One end of the third shaft rod 30 away from the second connecting rod 12 is rotatably connected to the one-way gear 45 through a one-way bearing. The circular gear groove 3 is fixedly connected to the main frame body 2. The one-way gear 45 meshes with the inner wall of the circular gear groove 3. The end of the second connecting rod 12 is fixedly connected to the first limiting plate 10. There are two of the two control mechanisms 303, and the two control mechanisms 303 are symmetrically distributed.

[0022] In this implementation, when in use, the annular part body 8 is placed in the storage bin 4. In the initial state, the feeding telescopic rod 1 is in a contracted state. A number of annular part bodies 8 are neatly stacked in the storage bin 4. Subsequently, the feeding telescopic rod 1 starts feeding, so that the push plate 13 pushes the lowermost 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 feeding telescopic rod 1 reciprocates telescopically, the one-way gear 45 will slide along the shape of the return gear groove 3. It is set that when the feeding telescopic rod 1 extends, the one-way gear 45 slides along the track on the side of the return gear groove 3 away from the storage bin 4. In this state, the first limiting plate 10 and the first limiting rod 9 are in a separated state and will not act on the second slider 25 and the first sliding rod 18.

[0023] Among them, the outer positioning mechanism 101 includes a first fixing plate 17, a support spring 22, two L-shaped polishing heads 7, two mounting sliders 16 and two first sliding rods 18. The first fixing plate 17 is fixedly connected to the main frame body 2. The two mounting sliders 16 are both slidably connected to the first fixing plate 17. The two first sliding rods 18 are respectively fixedly connected to the two mounting sliders 16. The two L-shaped polishing heads 7 are both fixedly connected to the two mounting sliders 16. The support spring 22 is fixedly connected between the two mounting sliders 16. There are two outer positioning mechanisms 101, and the two outer positioning mechanisms 101 are symmetrically distributed.

[0024] In this implementation, when the feeding telescopic rod 1 and the push plate 13 move the annular part body 8 to the specified processing position, that is Figure 1 the position where the annular part body 8 is located. Subsequently, the feeding telescopic rod 1 retracts. At this time, the two first limiting plates 10 move to the inner side of the return gear groove 3 along with the connecting rod two 12, the third shaft rod 30 and the one-way gear 45, that is Figure 10 the position shown in. So that the two first sliding rods 18 are inserted into the sliding grooves opened on the first limiting plate 10 at this time. Subsequently, when the feeding telescopic rod 1 retracts, the first sliding rods 18 are restricted by the sliding grooves opened on the first limiting plate 10, so that the two L-shaped polishing heads 7 approach each other until they are closely attached to the outer wall of the annular part body 8.

[0025] Among them, the inner positioning mechanism 404 includes a circular mounting plate 15, a rectangular mounting groove 14, a second sliding rod 21, an internal spring 44 and an inclined surface rack bar 43. The second sliding rod 21 is slidably 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 second sliding rod 21. The inclined surface rack bar 43 is arranged below the second sliding rod 21. The circular mounting plate 15 is fixedly connected to the L-shaped polishing head 7. The inclined surface rack bar 43 is slidably connected to the circular mounting plate 15. The rectangular mounting groove 14 is fixedly connected to the circular mounting plate 15.

[0026] Among them, the inner positioning mechanism 404 further includes a fourth gear 20, a third gear 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. The fourth gear 20 and the third gear 41 are respectively arranged on both sides of the circular mounting plate 15. The fourth gear 20 and the third gear 41 are respectively fixedly connected to both ends of the second shaft rod 42. The fourth gear 20 meshes with the outer wall of the inclined surface rack rod 43, and the outer wall of the third gear 41 meshes with the outer walls of the two connecting racks 40. The two connecting racks 40 are distributed in a circumferential array, and the two side polishing rods 39 are respectively fixedly connected to the ends of the two connecting racks 40.

[0027] In this implementation scheme, as Figures 7-9 shown, the lower L-shaped polishing head 7 drives the circular mounting plate 15 to move together, so that the side polishing rod 39 can be horizontal with the inner side wall of the annular part body 8. At the same time, the second sliding rod 21 is extruded and moves downward by the upper L-shaped polishing head 7, so as to contact the inclined end of the inclined surface rack rod 43, and push the inclined surface rack rod 43 to move close to the second shaft rod 42, thereby driving the fourth gear 20 to rotate. The fourth gear 20 drives the second shaft rod 42 and the third gear 41 to rotate, thereby driving the two connecting racks 40 to extend. The two side polishing rods 39 abut against the inner side wall of the annular part body 8, thereby completing the positioning of the all-round polishing assembly of the annular part body 8.

[0028] It is set that the length of the rectangular mounting groove 14 is less than the diameter of the annular part body 8, which is convenient for the rectangular mounting groove 14 to move upward without causing the displacement of the annular part body 8, and ensures the accuracy of the position of the annular part body 8.

[0029] Among them, the driving mechanism 202 includes two first limiting rods 9, two second fixing plates 23, two return springs 24 and two second sliders 25. The two first limiting rods 9 are respectively fixedly connected to the two first limiting plates 10. The two second fixing plates 23 are both fixedly connected to the main frame body 2. The two second sliders 25 are both slidably connected to the second fixing plates 23. The two return springs 24 are respectively fixedly connected between the two second sliders 25 and the second fixing plates 23.

[0030] Among them, the driving mechanism 202 further includes an arc-shaped mounting frame 6, a motor mounting frame 35, a driving motor 34, a second gear 33, a rotating ring 19, an upper gear set 31 and a side gear set 32. The two ends of the arc-shaped mounting frame 6 are fixedly connected to the two second sliders 25. The motor mounting frame 35 is fixedly connected to the arc-shaped mounting frame 6. The driving motor 34 is fixedly connected to the motor mounting frame 35. The second gear 33 is fixedly connected to the output shaft of the driving motor 34. The rotating ring 19 is slidably connected to the outer wall of the arc-shaped mounting frame 6. The upper gear set 31 is fixedly connected to the top outer wall of the rotating ring 19. The side gear set 32 is fixedly connected to the inner ring side wall of the rotating ring 19. The second gear 33 meshes with the side gear set 32.

[0031] Among them, the driving mechanism 202 further includes a number of first gears 29, a number of first shaft rods 28, a number of clamping seats 27 and a number of clamping heads 26. The first shaft rod 28 is rotatably connected to the arc-shaped mounting bracket 6. The first gear 29 is fixedly connected to the first shaft rod 28. The first shaft rod 28 meshes with the outer wall of the first gear 29. The clamping seat 27 is fixedly connected to the first shaft rod 28. The clamping head 26 is slidably connected to the clamping seat 27.

[0032] Among them, two driving mechanisms 202 are arranged in a vertically symmetric distribution. A strong spring 36 is fixedly connected to the inner wall of each clamping seat 27. A number of pull ropes 37 are fixedly connected to the inner wall of each clamping seat 27. One end of each pull rope 37 away from the clamping seat 27 is fixedly connected to the suction cup 38. The edge of each suction cup 38 is fixedly connected to the clamping head 26.

[0033] In this implementation scheme, as Figures 4-6 shown, when the feeding telescopic rod 1 continues to move backward, the first limiting rod 9 abuts against the second slider 25. At this time, the ends of the upper and lower second sliders 25 are located directly below and directly above the first limiting rod 9. The first limiting rod 9 drives the two second sliders 25 and the arc-shaped mounting bracket 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 part body 8. At the same time, since the suction cup 38 contacts the surface of the annular part body 8, when the clamping head 26 retracts, the clamping seat 27 is pulled, so that the suction cup 38 generates a negative pressure on the annular part body 8, enhancing the clamping force.

[0034] Subsequently, when the driving motor 34 is started, the second gear 33 drives the side gear group 32 and the rotating ring 19 to rotate. The rotating ring 19 drives a number of first gears 29 to rotate through the upper gear group 31. Thus, the upper and lower layers of a number of clamping heads 26 drive the annular part body 8 to rotate for polishing. After the polishing is completed, the feeding telescopic rod 1 retracts to its original position and then extends, driving the next annular part body 8 to be fed 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. The two second sliders 25 are separated by the force of the return spring 24. Thus, 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 designated position, the polished annular part body 8 slides down along the inclined surface of the main frame body 2 due to the action of gravity and is automatically discharged.

[0035] The specific working principle and usage method of the present invention will be explained in detail as follows: During use, the annular part body 8 is placed in the storage bin 4. In the initial state, the feeding telescopic rod 1 is in a contracted state, and several annular part bodies 8 are neatly stacked in the storage bin 4. Subsequently, the feeding telescopic rod 1 starts feeding, causing the push plate 13 to push the lowermost 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 feeding telescopic rod 1 reciprocates, the one-way gear 45 will slide along the shape of the loop gear groove 3. It is set that when the feeding telescopic rod 1 extends, the one-way gear 45 slides along the track on the side of the loop gear groove 3 away from the storage bin 4. In this state, the first limiting plate 10 and the first limiting rod 9 are in a separated state and will not act on the second slider 25 and the first sliding rod 18.

[0036] When the feeding telescopic rod 1 and the push plate 13 drive the annular part body 8 to move to the specified processing position, that is, Figure 1 the position where the annular part body 8 is located in, and then the feeding telescopic rod 1 retracts. At this time, the two first limiting plates 10 move to the inner side of the loop gear groove 3 along with the connecting rod two 12, the third shaft rod 30 and the one-way gear 45, that is, Figure 10 the position shown in, so that the two first sliding rods 18 are inserted into the sliding grooves opened on the first limiting plate 10 at this time. Subsequently, when the feeding telescopic rod 1 retracts, the first sliding rods 18 are restricted by the sliding grooves opened on the first limiting plate 10, causing the two L-shaped polishing heads 7 to approach each other until they are closely attached to the outer wall of the annular part body 8.

[0037] As Figures 7-9 shown, the lower L-shaped polishing head 7 drives the circular mounting plate 15 to move together, so that the side polishing rod 39 can be horizontal with the inner side wall of the annular part body 8. At the same time, the second sliding rod 21 is pushed downward by the upper L-shaped polishing head 7 and thus abuts against the inclined end of the inclined surface rack rod 43, pushing the inclined surface rack rod 43 to move closer to the second shaft rod 42, thereby driving the gear four 20 to rotate. The gear four 20 drives the second shaft rod 42 and the gear three 41 to rotate, thereby driving the two connecting racks 40 to extend. The two side polishing rods 39 abut against the inner side wall of the annular part body 8, thus completing the positioning of the all-round polishing assembly of the annular part body 8.

[0038] It is set that the length of the rectangular mounting groove 14 is less than the diameter of the annular part body 8, which is convenient for the rectangular mounting groove 14 to move upward without causing the displacement of the annular part body 8, ensuring the accuracy of the position of the annular part body 8.

[0039] As Figures 4-6As shown, when the feeding telescopic rod 1 continues to move backward, the limit rod 1 9 conflicts 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.

[0040] Subsequently, 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, 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 separated by the force of the supporting spring 22, 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 unloads automatically.

[0041] 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 conventional means well known to those skilled in the art.

[0042] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
