Description

Technical Field

[0001] This invention relates to the field of accessory polishing technology, and in particular to an accessory polishing device and process for the production of ceramic fiber brushes. Background Technology

[0002] Ceramic fiber brushes are widely used in deburring and polishing of both metallic and non-metallic materials. During their production, the inner walls of brush body accessories (especially tubular or cylindrical accessories) need to be polished efficiently and evenly.

[0003] A search revealed Chinese patent CN117444731B, which discloses a grinding device and method for smelting metals of different sizes. The device includes a worktable with a multi-angle integrated grinding mechanism for conical, cylindrical, and tubular metals of different sizes. This mechanism enables grinding of both cylindrical and conical metal workpieces. Furthermore, the fixing method and grinding angle can be adjusted according to the slope of the conical tubular metal, thus adapting to grinding conical tubular metals with different slopes, making it widely applicable.

[0004] Based on the above research and existing technology, it was found that existing cylindrical ceramic fiber brushes use a radially expandable or retractable grinding disc during the grinding process. This disc extends into the inner cavity of the component and rotates at high speed to complete the grinding operation. When grinding components of different diameters, operators must manually input commands or select preset programs via buttons on the equipment control panel according to the target diameter of the component. This controls the drive mechanism to move and position the grinding head to the preset working position corresponding to the component's diameter. Each time a component specification is changed, the operator must perform a series of button operations. On production lines requiring frequent changes in multiple varieties and small batches, this repetitive manual operation undoubtedly increases non-productive preparation time and reduces overall production efficiency. Operators may inadvertently input incorrect diameter values ​​or make incorrect selections in complex menus. Such human errors can lead to inaccurate grinding head positioning, potentially resulting in over- or under-grinding of components, producing scrap and directly causing economic losses.

[0017] The present invention also provides a polishing process for accessories used in the production of ceramic fiber brushes, the polishing process comprising the following steps:

[0018] Step 1: The ceramic fiber brush parts to be polished are loaded using a robotic arm and fixed in place using a fixing unit;

[0019] Step 2: The hydraulic cylinder drives the fixed plate, drive motor, rotating tube, guide rod, sliding block and grinding plate to move downward. When the grinding plate enters the part and contacts the inner wall of the part, the drive motor drives the rotating tube, guide rod, sliding block and grinding plate to rotate, so that the grinding plate grinds the inner wall of the part.

[0020] Step 3: By setting the adaptive adjustment unit, when the diameter of the part increases, more oil enters the rotating tube, and the sliding rod, U-shaped rod and sliding ring move downward a greater distance, which increases the distance the grinding plate moves outward and contacts the inner wall of the part. The system adaptively grinds parts of different diameters, and the ground parts can be automatically discharged.

[0021] This invention provides an improved accessory grinding equipment and process for the production of ceramic fiber brushes, which has the following improvements and advantages compared with the prior art:

[0022] Firstly, this invention, through the setting of an adaptive adjustment unit, when the grinding plate 1 enters the accessory, the extrusion column drives the sliding piston rod 1 into the fixed cylinder, so that the oil in the fixed cylinder enters the rotating tube through the connecting hose, the annular shell, and the through hole. This causes the oil to drive the sliding rod, the U-shaped rod, and the sliding ring to move downwards. The movement of the sliding ring, through the connecting block 1, the connecting rod, and the connecting block 2, causes the two sliding blocks to move away from each other, so that the two sliding blocks drive the two grinding plates 1 to contact the inner wall of the accessory. When the diameter of the accessory increases, the accessory extrusion fixing strip drives the sliding piston rod 2 into the fixed shell, so that more oil enters the rotating tube, and the downward distance of the sliding rod, the U-shaped rod, and the sliding ring increases, so that the grinding plate 1 moves outward a greater distance and contacts the inner wall of the accessory, thus achieving adaptive grinding of accessories with different diameters.

[0023] Secondly, through the setting of the grinding unit, when the accessory rotates to the lower part of the grinding plate, the hydraulic cylinder drives the fixed plate, drive motor, rotating tube, guide rod, sliding block and grinding plate to move downward. The movement of the fixed plate drives the extrusion column to move downward. When the grinding plate enters the accessory and contacts the inner wall of the accessory, the drive motor drives the rotating tube, guide rod, sliding block and grinding plate to rotate, so that the grinding plate grinds the inner wall of the accessory.

[0024] Thirdly, this invention, through the setting of an auxiliary grinding unit, allows two grinding plates to move outwards, and then the rotating plate drives the mounting block to move outwards. The movement of the mounting block drives the fixed tube, the sliding piston rod four, and the grinding plate two to move outwards. When the U-shaped rod moves downwards a greater distance, the U-shaped rod squeezes the sliding piston rod three into the mounting block. The sliding piston rod three squeezes the oil in the mounting block into the fixed tube, causing the oil to drive the sliding piston rod four and the grinding plate two to move, so that the grinding plate two contacts the inner wall of the accessory, thereby assisting in grinding and improving the grinding effect on larger diameter accessories.

[0025] Fourthly, this invention, through the setting of a fixed unit, uses a stepper motor to drive the rotating column and turntable to rotate intermittently. The rotation of the turntable drives the fixed rod, movable rod, and clamping plate to rotate in a circle. At the same time, the rotation of the turntable drives the fixed block, sliding column, and U-shaped bending rod to rotate in a circle. When the sliding column drives the cylindrical block to contact the arc-shaped extrusion rod, the arc-shaped extrusion rod drives the cylindrical block to move outward. The movement of the cylindrical block drives the sliding column and U-shaped bending rod to move. The sliding column drives the telescopic spring to compress and undergo elastic deformation. The movement of the U-shaped bending rod drives the two cylindrical rods to move closer to each other. The movement of the cylindrical rod drives the movable rod and clamping plate to move closer to clamp and fix the parts, thus realizing automatic fixing of the parts.

[0026] Fifthly: When the turntable of the present invention drives the parts to rotate, when the cylindrical block moves away from the arc-shaped extrusion rod, the telescopic spring drives the sliding column and the U-shaped bending rod to reset. The U-shaped bending rod drives the movable rod to move through the cylindrical rod, so that the two clamping plates move away from the parts. When the polished parts come into contact with the inclined rod, the inclined rod can squeeze the parts out of the feed port, and then enter the collection box through the guide plate for collection, thus realizing the collection of the polished parts.

[0038] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] This invention provides an improved accessory grinding equipment and process for the production of ceramic fiber brushes. The technical solution of this invention is as follows:

[0040] Example 1, as Figures 1 to 8 As shown, this embodiment of the invention provides a grinding device for accessories in the production of ceramic fiber brushes, including a frame 1, a mounting plate 11 fixedly connected to the frame 1, a hydraulic cylinder 12 fixedly connected to the mounting plate 11, and a fixing plate 13 fixedly connected to the bottom end of the hydraulic cylinder 12, and further including:

[0041] The grinding mechanism is located on the fixed plate 13;

[0042] The polishing mechanism includes an adaptive adjustment unit, a polishing unit, an auxiliary polishing unit, and a fixing unit. The polishing unit includes a drive motor 14 fixedly connected to a fixed plate 13. A rotating tube 15 is fixedly connected to the output end of the drive motor 14. The rotating tube 15 is rotatably connected to the fixed plate 13. Two guide rods 16 are fixedly connected to the bottom end of the rotating tube 15. Sliding blocks 17 are slidably connected to each of the two guide rods 16. A polishing plate 18 is fixedly connected to the bottom end of each of the two sliding blocks 17. A sliding rod 113 is slidably connected to the rotating tube 15. A U-shaped rod 114 is fixedly connected to the bottom end of the sliding rod 113. A sliding ring 19 is fixedly connected to the top end of the U-shaped rod 114. The sliding ring 19 is slidably connected to the rotating tube 15. Two connecting blocks 110 are fixedly connected to the sliding ring 19. Two connecting blocks 2 are fixedly connected to the top ends of each of the two sliding blocks 17. 112, two connecting blocks 110 and two connecting blocks 112 are rotatably connected to connecting rods 111, and a circular shell 24 is fixedly connected to the fixed plate 13. The circular shell 24 is rotatably connected to the rotating tube 15. The rotating tube 15 has a through hole 25, which communicates with the circular shell 24. With the setting of the grinding unit, when the accessory rotates to the bottom of the grinding plate 18, the hydraulic cylinder 12 drives the fixed plate 13, the drive motor 14, the rotating tube 15, the guide rod 16, the sliding block 17 and the grinding plate 18 to move downward. The movement of the fixed plate 13 drives the extrusion column 210 to move downward. When the grinding plate 18 enters the accessory and contacts the inner wall of the accessory, the drive motor 14 drives the rotating tube 15, the guide rod 16, the sliding block 17 and the grinding plate 18 to rotate, so that the grinding plate 18 grinds the inner wall of the accessory.

[0043] Furthermore, the adaptive adjustment unit includes a worktable 4 fixedly connected to the frame 1. A fixed cylinder 2 is fixedly connected to the top of the worktable 4. A fixed shell 26 is fixedly connected to the fixed cylinder 2. A sliding piston rod 27 is slidably connected to the fixed shell 26. A fixing strip 28 is fixedly connected to one end of the sliding piston rod 27. A connecting hose 23 is fixedly connected to the fixed cylinder 2. One end of the connecting hose 23 is fixedly connected to the annular shell 24. A sliding piston rod 21 is slidably connected to the fixed cylinder 2. A pressing column 210 is fixedly connected to the bottom of the fixed plate 13. The pressing column 210 is located directly above the sliding piston rod 21. A return spring 29 is sleeved on the sliding piston rod 27. The two ends of the return spring 29 are fixedly connected to the fixed shell 26 and the fixing strip 28, respectively. Through the setting of the adaptive adjustment unit, when the grinding plate 18 enters the accessory, the pressing column 210... The sliding piston rod 21 enters the fixed cylinder 2, causing the oil in the fixed cylinder 2 to enter the rotating tube 15 through the connecting hose 23, the annular shell 24, and the through hole 25. This causes the oil to drive the sliding rod 113, the U-shaped rod 114, and the sliding ring 19 downwards. The movement of the sliding ring 19, through the connecting block 110, the connecting rod 111, and the connecting block 212, causes the two sliding blocks 17 to move away from each other. This causes the two sliding blocks 17 to drive the two grinding plates 18 to contact the inner wall of the accessory. When the diameter of the accessory increases, the accessory squeezes the fixing strip 28, causing the sliding piston rod 27 to enter the fixed shell 26. This increases the amount of oil entering the rotating tube 15, and the downward movement distance of the sliding rod 113, the U-shaped rod 114, and the sliding ring 19 increases. This also increases the outward movement distance of the grinding plate 18, which then contacts the inner wall of the accessory, thus achieving adaptive grinding of accessories with different diameters.

[0044] Furthermore, a compression spring 22 is sleeved on the sliding piston rod 21, and the two ends of the compression spring 22 are fixedly connected to the fixed cylinder 2 and the sliding piston rod 21 respectively; by setting the compression spring 22, the compression spring 22 can drive the sliding piston rod 21 to reset.

[0045] Furthermore, two guide posts 115 are fixedly connected to the top of the fixing plate 13, and the two guide posts 115 are slidably connected to the mounting plate 11; the setting of the guide posts 115 improves the stability of the fixing plate 13.

[0046] Furthermore, the auxiliary polishing unit includes rotating plates 3 rotatably connected to polishing plates 18, with mounting blocks 31 rotatably connected to one end of each rotating plate 3. A fixed tube 34 is fixedly connected to the mounting block 31, and a sliding piston rod 35 is slidably connected to the fixed tube 34. One end of the sliding piston rod 35 is fixedly connected to a polishing plate 36, and a sliding piston rod 32 is slidably connected to the mounting block 31. Through the auxiliary polishing unit, the two polishing plates 18 move outward, and the rotating plates 3 then drive the mounting block 31 outward. The moving mounting block 31 causes the fixed tube 34, the sliding piston rod 35, and the grinding plate 36 to move outward. As the U-shaped rod 114 moves downward, it squeezes the sliding piston rod 32 into the mounting block 31. The sliding piston rod 32 then squeezes the oil in the mounting block 31 into the fixed tube 34, causing the oil to move the sliding piston rod 35 and the grinding plate 36. This allows the grinding plate 36 to contact the inner wall of the accessory, thus assisting in grinding and improving the grinding effect on larger diameter accessories.

[0047] Furthermore, a connecting spring 33 is sleeved on the sliding piston rod 32, and the two ends of the connecting spring 33 are fixedly connected to the mounting block 31 and the sliding piston rod 32 respectively; through the setting of the connecting spring 33, the connecting spring 33 can drive the sliding piston rod 32 to reset.

[0048] Furthermore, the fixing unit includes a stepper motor 41 fixedly connected to the workbench 4, a rotating column 42 fixedly connected to the output end of the stepper motor 41, the rotating column 42 being rotatably connected to the workbench 4, a turntable 43 fixedly connected to the top of the rotating column 42, multiple feed ports 410 opened on the turntable 43, multiple fixed rods 5 fixedly connected to the bottom end of the turntable 43, movable rods 51 slidably connected to the multiple fixed rods 5, and a clamping plate 52 fixedly connected to one end of each of the multiple movable rods 51. Each movable rod 51 has a cylindrical rod 53 fixedly connected to its bottom. Multiple fixed blocks 44 are fixedly connected to the bottom of each turntable 43. Sliding columns 45 are slidably connected to each of the fixed blocks 44. A U-shaped bent rod 46 is fixedly connected to one end of each sliding column 45. Each U-shaped bent rod 46 has two slotted holes. The bottom ends of the multiple cylindrical rods 53 extend into the corresponding slotted holes. A cylindrical block 47 is fixedly connected to the other end of each sliding column 45. An arc-shaped extruder is fixedly connected to the top of the worktable 4. The pressure rod 48 has two cylindrical blocks 47 in contact with the arc-shaped extrusion rod 48. A telescopic spring 49 is sleeved on the sliding column 45, and the two ends of the telescopic spring 49 are fixedly connected to the sliding column 45 and the fixed block 44, respectively. Through the setting of the fixing unit, the stepper motor 41 rotates to drive the rotating column 42 and the turntable 43 to rotate intermittently. The rotation of the turntable 43 drives the fixed rod 5, the movable rod 51 and the clamping plate 52 to rotate in a circle. At the same time, the rotation of the turntable 43 drives the fixed block 44, the sliding column 45 and the U-shaped bend to rotate in a circle. The rod 46 rotates in a circle. When the sliding column 45 drives the cylindrical block 47 to contact the arc-shaped extrusion rod 48, the arc-shaped extrusion rod 48 drives the cylindrical block 47 to move outward. The movement of the cylindrical block 47 drives the sliding column 45 and the U-shaped bending rod 46 to move. The sliding column 45 drives the telescopic spring 49 to compress and undergo elastic deformation. The movement of the U-shaped bending rod 46 drives the two cylindrical rods 53 to move closer to each other. The movement of the cylindrical rods 53 drives the movable rod 51 and the clamping plate 52 to move closer to clamp and fix the parts, thus realizing the automatic fixing of the parts.

[0049] Furthermore, a guide plate 61 and a diagonal rod 6 are fixedly connected to the workbench 4, and a collection box 62 is fixedly connected to the frame 1. The guide plate 61 is located directly above the collection box 62. With the diagonal rod 6, when the turntable 43 drives the parts to rotate, when the cylindrical block 47 moves away from the arc-shaped extrusion rod 48, the telescopic spring 49 drives the sliding column 45 and the U-shaped bending rod 46 to reset. The U-shaped bending rod 46 drives the movable rod 51 to move through the cylindrical rod 53, so that the two clamping plates 52 move away from the parts. When the polished parts come into contact with the diagonal rod 6, the diagonal rod 6 can squeeze the parts out from the feed port 410, and then collect them in the collection box 62 through the guide plate 61, thus realizing the collection of the polished parts.

[0050] Example 2: This example also discloses a polishing process for accessories used in the production of ceramic fiber brushes. The polishing process includes the following steps:

[0051] Step 1: The ceramic fiber brush parts to be polished are loaded using a robotic arm and fixed in place using a fixing unit;

[0052] Step 2: The hydraulic cylinder 12 drives the fixed plate 13, drive motor 14, rotating tube 15, guide rod 16, sliding block 17 and grinding plate 18 to move downward. When the grinding plate 18 enters the part and contacts the inner wall of the part, the drive motor 14 drives the rotating tube 15, guide rod 16, sliding block 17 and grinding plate 18 to rotate, so that the grinding plate 18 grinds the inner wall of the part.

[0053] Step 3: By setting the adaptive adjustment unit, when the diameter of the accessory increases, more oil enters the rotating tube 15, and the sliding rod 113, U-shaped rod 114 and sliding ring 19 move downward a greater distance, which increases the distance the grinding plate 18 moves outward and contacts the inner wall of the accessory. The accessory with different diameters is ground adaptively, and the ground accessory can be automatically discharged.

[0054] Specific implementation steps: The part to be ground is placed into the feed inlet 410 opposite the fixed cylinder 2 by a mechanical gripper. The stepper motor 41 rotates, driving the rotating column 42 and the turntable 43 to rotate intermittently. The rotation of the turntable 43 drives the fixed rod 5, the movable rod 51, and the clamping plate 52 to rotate in a circle. At the same time, the rotation of the turntable 43 drives the fixed block 44, the sliding column 45, and the U-shaped bending rod 46 to rotate in a circle. When the sliding column 45 drives the cylindrical block 47 to contact the arc-shaped extrusion rod 48, the arc-shaped extrusion rod 48 drives the cylindrical block 47 to move outward. The movement of the cylindrical block 47 drives the sliding column 45 and the U-shaped bending rod 46 to move. The sliding column 45 drives the telescopic spring 49 to compress and undergo elastic deformation. The movement of the U-shaped bending rod 46 drives the two cylindrical rods 53 to move closer to each other. The cylindrical rods 53 move... The moving rod 51 and clamping plate 52 are brought close to clamp and fix the part, thus automatically fixing the part. When the part rotates to below the grinding plate 18, the hydraulic cylinder 12 drives the fixed plate 13, drive motor 14, rotating tube 15, guide rod 16, sliding block 17 and grinding plate 18 to move downward. The movement of the fixed plate 13 drives the extrusion column 210 to move downward. When the grinding plate 18 enters the part, the extrusion column 210 contacts the sliding piston rod 21 and drives the sliding piston rod 21 into the fixed cylinder 2, so that the oil in the fixed cylinder 2 enters the annular shell 24 through the connecting hose 23, and then enters the rotating tube 15 through the through hole 25, so that the oil extrudes the sliding rod 113 to move downward. The movement of the sliding rod 113 drives the extrusion spring 22 to move downward. The compression and elastic deformation of the sliding rod 113 cause the U-shaped rod 114 and sliding ring 19 to move downwards. The movement of the sliding ring 19, through connecting block 110, connecting rod 111, and connecting block 112, causes the two sliding blocks 17 to move away from each other, so that the two sliding blocks 17 drive the two grinding plates 18 to contact the inner wall of the accessory. The drive motor 14 is started, which drives the rotating tube 15, guide rod 16, sliding blocks 17, and grinding plates 18 to rotate, so that the grinding plates 18 grind the inner wall of the accessory. When the diameter of the accessory increases, the accessory squeezes the fixing strip 28, causing the sliding piston rod 27 to enter the fixed shell 26, which increases the amount of oil entering the rotating tube 15, and increases the downward movement distance of the sliding rod 113, U-shaped rod 114, and sliding ring 19. This increases the outward movement distance of the grinding plate 18, bringing it into contact with the inner wall of the component. This enables adaptive grinding of components of different diameters. The outward movement of the two grinding plates 18, along with the movement of the rotating plate 3, causes the mounting block 31 to move outward. The movement of the mounting block 31 then moves the fixed tube 34, the sliding piston rod 35, and the grinding plate 36 outward. As the downward movement of the U-shaped rod 114 increases, it compresses the sliding piston rod 32 into the mounting block 31. The movement of the sliding piston rod 32 compresses the connecting spring 33, causing it to elastically deform. The sliding piston rod 32 then forces the oil from the mounting block 31 into the fixed tube 34. This oil then moves the sliding piston rod 35 and the grinding plate 36, bringing the grinding plate 36 into contact with the inner wall of the component.This assists in grinding, improving the grinding effect on larger diameter parts. After grinding, the hydraulic cylinder 12 drives the fixed plate 13 and grinding plate 18 to reset. When the turntable 43 rotates the part, when the cylindrical block 47 moves away from the arc-shaped extrusion rod 48, the telescopic spring 49 drives the sliding column 45 and U-shaped bending rod 46 to reset. The U-shaped bending rod 46 drives the movable rod 51 to move through the cylindrical rod 53, causing the two clamping plates 52 to move away from the part. When the ground part comes into contact with the inclined rod 6, the inclined rod 6 can squeeze the part out of the feed port 410, and then collect it in the collection box 62 through the guide plate 61, realizing the discharge and collection of the ground part.
