Description

Technical Field

[0001] This utility model belongs to the field of ceramic grinding roller and grinding wheel technology, and particularly relates to a ceramic grinding roller and grinding wheel. Background Technology

[0002] Ceramic grinding rollers are a special type of grinding wheel, mainly composed of abrasives, ceramic binders, and other additives, and manufactured through a high-temperature sintering process. They have a wide range of applications in the machining field, especially in the steel industry, where they are used for surface finishing of special steel, steel billets, and steel ingots, as well as surface treatment of various castings. In addition, they can also be used to grind various crankshafts and camshafts of automotive and transportation machinery engines, featuring high grinding efficiency, good wear resistance, and high surface finish.

[0003] Traditional ceramic grinding rollers have an integral outer and inner wheel structure. When the outer wheel wears out or breaks after prolonged use, the user needs to replace the entire ceramic grinding roller due to its integral structure, resulting in high replacement costs. Therefore, we propose a new type of ceramic grinding roller. Utility Model Content

[0004] The purpose of this invention is to provide a ceramic grinding roller to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a ceramic grinding roller, comprising an outer grinding wheel and an inner grinding wheel, wherein the inner grinding wheel is disposed inside the outer grinding wheel, and further comprising:

[0006] A retaining ring is fixedly connected to the inner wall of the outer wheel of the grinding wheel. The retaining ring has a slot, and the inner wheel of the grinding wheel is located in the slot and is inserted into the slot.

[0007] Multiple grooves are formed inside the inner wheel of the grinding wheel and are connected to the inner wall of the slot. Multiple inserts are slidably connected in the multiple grooves, and one end of each insert extends to the inner wall of the slot and engages with the slot. Multiple first threaded rods are threadedly connected in the multiple inserts.

[0008] Multiple first rotating grooves are formed inside the inner wheel of the grinding wheel and are respectively connected to multiple sliding grooves. Multiple bevel gears are rotatably connected in the multiple first rotating grooves, and one end of each bevel gear extends into the multiple sliding grooves and is fixed to one end of each of the multiple first threaded rods.

[0009] A drive assembly located inside the inner wheel of the grinding wheel and used to drive multiple bevel gears to rotate.

[0010] Based on the above structure, the slot and inner wheel of the grinding wheel ensure that the inner wheel can be inserted into the slot. The slide and insert block ensure that the insert block can slide in the slide. The first threaded rod ensures that when the multiple first threaded rods rotate, the multiple insert blocks will be acted upon by the threads of the multiple first threaded rods, moving away from or towards each other. When the multiple insert blocks move away from each other to a suitable position, they will fix the inner wheel of the grinding wheel in the slot. When they move closer to each other to a suitable position, they will release the fixation on the inner wheel of the grinding wheel, allowing the user to replace the outer wheel of the grinding wheel. The first rotating groove and bevel gear ensure that the multiple bevel gears can rotate in the multiple first rotating grooves, allowing one end of each bevel gear to drive the multiple first threaded rods to rotate.

[0011] In the above technical solution, the driving component further includes:

[0012] The second rotating groove is formed inside the inner wheel of the grinding wheel and is connected to multiple first rotating grooves. A bevel gear ring that meshes with multiple bevel gears is rotatably connected inside the second rotating groove. A toothed ring is fixedly connected to the inner wall of the bevel gear ring, and the toothed ring is located inside the second rotating groove and rotatably connected to the second rotating groove.

[0013] The third rotating groove is formed inside the inner wheel of the grinding wheel and is connected to the second rotating groove. A gear that meshes with a gear ring is rotatably connected inside the third rotating groove. A first rotating rod is fixedly connected to the gear, and one end of the first rotating rod passes through the inner wall of the third rotating groove and extends to the outside to be rotatably connected to the inner wheel of the grinding wheel.

[0014] A fixing component is located on the first rotating rod and is used to fix the first rotating rod.

[0015] This technical solution ensures that users can replace the outer grinding wheel.

[0016] In the above technical solution, the fixing component further includes:

[0017] Two second threaded rods are rotatably connected to a first rotating rod, and a pressing block is threaded between the two second threaded rods, with the pressing block disposed on the circumference of the first rotating rod;

[0018] The movable groove is formed inside the first rotating rod. Two sprockets are rotatably connected inside the movable groove, and one end of each sprocket penetrates the inner wall of the movable groove and extends into the first rotating rod, respectively fixed to one end of each of the two second threaded rods. A chain meshes between the two sprockets. A second rotating rod is fixedly connected to one of the sprockets, and one end of the second rotating rod penetrates the inner wall of the movable groove and extends to the outside, rotatably connected to the first rotating rod.

[0019] In this technical solution, it is ensured that the first rotating rod can be fixed on the inner wheel of the grinding wheel and cannot rotate, thus preventing the first rotating rod from rotating due to external influences.

[0020] In the above technical solution, one end of each of the two sprockets is rotatably connected to the first rotating rod.

[0021] In this technical solution, it is ensured that one end of each of the two sprockets can rotate normally within the first rotating rod.

[0022] Furthermore, in the above technical solution, the threads on the two second threaded rods have the same direction of rotation.

[0023] In this technical solution, it is ensured that when the two second threaded rods rotate, the extrusion block will move due to the action of the threads of the two second threaded rods.

[0024] In the above technical solution, the extrusion block is further slidably connected to the periphery of the first rotating rod.

[0025] In this technical solution, it is ensured that the extrusion block can slide normally on the circumference of the first rotating rod.

[0026] In the above technical solution, one end of the bevel gear is rotatably connected to the sliding groove.

[0027] In this technical solution, it is ensured that one end of the bevel gear can rotate normally within the groove.

[0028] The beneficial effects of this utility model are:

[0029] 1. This ceramic grinding roller, through its slot and inner wheel, ensures that the inner wheel can be inserted into the slot. Through its sliding groove and insert blocks, it ensures that the insert blocks can slide within the sliding groove. Through its first threaded rods, it ensures that when multiple first threaded rods rotate, multiple insert blocks are acted upon by the threads of the first threaded rods, moving away from or towards each other. When the multiple insert blocks move away to a suitable position, they fix the inner wheel in the slot. When they move towards a suitable position, they release the fixation of the inner wheel, allowing the user to replace the outer wheel. Through its first rotating groove and bevel gears, it ensures that multiple bevel gears can rotate within their respective first rotating grooves, allowing one end of each bevel gear to drive the first threaded rods to rotate. This solves the problem that when the outer wheel wears out or breaks during prolonged use, the integrated structure of the outer and inner wheels of the ceramic grinding roller requires the user to replace the entire grinding roller, resulting in high replacement costs.

[0030] 2. This ceramic grinding roller, through the setting of a first rotating rod and a second threaded rod, ensures that the two second threaded rods can rotate on the first rotating rod. Through the setting of a movable groove, sprocket, chain, and second rotating rod, it is ensured that when the user rotates the second rotating rod, the second rotating rod will drive one of the sprockets to rotate in the movable groove, allowing one of the sprockets to drive the other sprocket to rotate through the chain. When the two sprockets rotate, they will drive the two second threaded rods to rotate respectively. Through the setting of a pressing block, it is ensured that when the two second threaded rods rotate, the pressing block will be acted upon by the threads of the two second threaded rods, moving along the circumference of the first rotating rod towards the inner wheel of the grinding wheel. When the pressing block moves to a position where it cannot move further, the pressing block will press against the inner wheel of the grinding wheel, fixing the first rotating rod in place and ensuring that the first rotating rod will not be affected by external factors and will not rotate.

[0043] Please see Figure 1 - Figure 5 As shown, this embodiment provides a ceramic grinding roller, including an outer grinding wheel 1 and an inner grinding wheel 4, wherein the inner grinding wheel 4 is disposed inside the outer grinding wheel 1, and further includes:

[0044] The fixing ring 2 is fixedly connected to the inner wall of the outer wheel 1 of the grinding wheel. The fixing ring 2 has a slot 3, and the inner wheel 4 of the grinding wheel is located in the slot 3 and is inserted into the slot 3.

[0045] Multiple sliding grooves 5 are formed inside the inner wheel 4 of the grinding wheel and are connected to the inner wall of the slot 3. Multiple inserts 6 are slidably connected in the multiple sliding grooves 5, and one end of each insert 6 extends to the inner wall of the slot 3 and is inserted into the slot 3. Multiple first threaded rods 7 are threadedly connected in the multiple inserts 6.

[0046] Multiple first rotating grooves 8 are formed inside the inner wheel 4 of the grinding wheel and are respectively connected to multiple sliding grooves 5. Multiple bevel gears 9 are rotatably connected in the multiple first rotating grooves 8, and one end of each bevel gear 9 extends into the multiple sliding grooves 5 and is respectively fixed to one end of each of the multiple first threaded rods 7.

[0047] The drive assembly is located inside the inner wheel 4 of the grinding wheel and is used to drive multiple bevel gears 9 to rotate. Example

[0048] This embodiment provides a ceramic grinding roller, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the driving component includes:

[0049] The second rotating groove 10 is opened in the inner wheel 4 of the grinding wheel and is connected to multiple first rotating grooves 8. A bevel ring 11 that meshes with multiple bevel gears 9 is rotatably connected in the second rotating groove 10. A toothed ring 12 is fixedly connected to the inner wall of the bevel ring 11, and the toothed ring 12 is located in the second rotating groove 10 and is rotatably connected to the second rotating groove 10.

[0050] The third rotating groove 13 is opened in the inner wheel 4 of the grinding wheel and is connected to the second rotating groove 10. A gear 14 that meshes with the gear ring 12 is rotatably connected in the third rotating groove 13. A first rotating rod 15 is fixedly connected to the gear 14, and one end of the first rotating rod 15 passes through the inner wall of the third rotating groove 13 and extends to the outside to be rotatably connected to the inner wheel 4 of the grinding wheel.

[0051] A fixing component is located on the first rotating rod 15 and is used to fix the first rotating rod 15.

[0052] When the outer grinding wheel 1 experiences significant wear or breakage after prolonged use, the user manually rotates the first rotating rod 15, causing the gear 14 to rotate within the third rotating groove 13. This causes the gear 14 to rotate the gear ring 12 within the second rotating groove 10, which in turn rotates the bevel gear ring 11 within the second rotating groove 10. As the bevel gear ring 11 rotates, it drives multiple bevel gears 9 to rotate within multiple first rotating grooves 8. One end of each bevel gear 9 drives multiple first threaded rods 7 to rotate within multiple sliding grooves 5. When the first threaded rods 7 rotate, multiple inserts 6 are acted upon by the threads of the first threaded rods 7, causing them to move closer together along the sliding grooves 5. When the inserts 6 reach a suitable position, one end of each insert 6 enters the sliding grooves 5 from the inner wall of the slot 3. At this point, the inner grinding wheel 4 is released from its fixation. The user then manually pulls the inner grinding wheel 4 out of the slot 3 and performs the necessary repairs on the outer grinding wheel 1 and the fixing ring 2. After replacement, the user manually inserts the inner grinding wheel 4 into the slot 3. Then, the user manually rotates the first rotating rod 15 in the reverse direction, causing the first rotating rod 15 to drive the gear 14 to rotate in the reverse direction in the third rotating groove 13. This causes the gear 14 to drive the gear ring 12 to rotate in the reverse direction in the second rotating groove 10, which in turn drives the bevel gear ring 11 to rotate in the reverse direction in the second rotating groove 10. When the bevel gear ring 11 rotates in the reverse direction, it drives multiple bevel gears 9 to rotate in the reverse direction in multiple first rotating grooves 8. One end of each bevel gear 9 drives multiple first threaded rods 7 to rotate in the reverse direction in multiple sliding grooves 5. When the multiple first threaded rods 7 rotate in the reverse direction, multiple insert blocks 6 are acted upon by the threads of the multiple first threaded rods 7, moving away from each other along multiple sliding grooves 5. When the multiple insert blocks 6 are moved away from each other to a suitable position, one end of each insert block 6 will be inserted into the inner wall of the slot 3 from multiple sliding grooves 5, fixing the inner grinding wheel 4 in the slot 3 so that it cannot move, ensuring that the user can replace the outer grinding wheel 1. Example

[0053] This embodiment provides a ceramic grinding roller, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a fixing component:

[0054] Two second threaded rods 16 are rotatably connected to the first rotating rod 15, and a pressing block 17 is threaded between the two second threaded rods 16, and the pressing block 17 is disposed on the periphery of the first rotating rod 15.

[0055] The movable groove 18 is formed inside the first rotating rod 15. Two sprockets 19 are rotatably connected inside the movable groove 18, and one end of each sprocket 19 passes through the inner wall of the movable groove 18 and extends into the first rotating rod 15. They are respectively fixed to one end of each of the two second threaded rods 16. A chain 20 meshes between the two sprockets 19. A second rotating rod 21 is fixedly connected to one of the sprockets 19, and one end of the second rotating rod 21 passes through the inner wall of the movable groove 18 and extends to the outside, where it is rotatably connected to the first rotating rod 15.

[0056] In operation, the user manually rotates the second rotating rod 21, causing one of the sprockets 19 to rotate within the movable groove 18. This causes the sprocket 19 to drive the other sprocket 19 via the chain 20. As both sprockets 19 rotate, one end of each sprocket drives the two second threaded rods 16 to rotate. When the two second threaded rods 16 rotate, the pressing block 17 is acted upon by the threads of the two second threaded rods 16, moving along the circumference of the first rotating rod 15 towards the inner wheel 4 of the grinding wheel. When the pressing block 17 reaches a position where it cannot move further, it presses tightly against the inner wheel 4 of the grinding wheel, ensuring that the first rotating rod 15 is fixed to the inner wheel 4 and cannot rotate, thus preventing the first rotating rod 15 from rotating due to external influences. Example

[0057] This embodiment provides a ceramic grinding roller, which, in addition to the technical solution of the above embodiment, also has the following technical features: one end of each of the two sprockets 19 is rotatably connected to the first rotating rod 15.

[0058] Specifically, it is ensured that one end of each of the two sprockets 19 can rotate normally within the first rotating rod 15. Example

[0059] This embodiment provides a ceramic grinding roller, which, in addition to the technical solution of the above embodiment, also has the following technical features: the threads on the two second threaded rods 16 have the same direction of rotation.

[0060] Specifically, it is ensured that when the two second threaded rods 16 rotate, the pressing block 17 will move due to the action of the threads of the two second threaded rods 16. Example

[0061] This embodiment provides a ceramic grinding roller, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the extrusion block 17 is slidably connected to the circumferential side of the first rotating rod 15.

[0062] Specifically, it is ensured that the extrusion block 17 can slide normally on the circumference of the first rotating rod 15. Example

[0063] This embodiment provides a ceramic grinding roller, which, in addition to the technical solutions of the above embodiments, also has the following technical features: one end of the bevel gear 9 is rotatably connected to the slide groove 5.

[0064] This ensures that one end of the bevel gear 9 can rotate normally within the slide groove 5.

[0065] When the outer grinding wheel 1 experiences significant wear or breakage after prolonged use, the user manually rotates the first rotating rod 15. This causes the first rotating rod 15 to drive the gear 14 to rotate within the third rotating groove 13. The gear 14 then drives the gear ring 12 to rotate within the second rotating groove 10. The gear ring 12 then drives the bevel gear ring 11 to rotate within the second rotating groove 10. As the bevel gear ring 11 rotates, it drives multiple bevel gears 9 to rotate within multiple first rotating grooves 8. One end of each bevel gear 9 drives multiple first threaded rods 7 to rotate within multiple sliding grooves 5. When the multiple first threaded rods 7 rotate, the multiple inserts 6 are respectively acted upon by the threads of the multiple first threaded rods 7, moving along the multiple sliding grooves. 5. When multiple insert blocks 6 approach each other to a suitable position, one end of each insert block 6 will enter the multiple sliding grooves 5 from the inner wall of the slot 3. At this time, the fixing of the inner wheel 4 of the grinding wheel will be released. Then, the user manually pulls the inner wheel 4 of the grinding wheel out of the slot 3, and then replaces the outer wheel 1 of the grinding wheel and the fixing ring 2. After the replacement is completed, the user manually inserts the inner wheel 4 of the grinding wheel into the slot 3. Then, the user manually rotates the first rotating rod 15 in the opposite direction, so that the first rotating rod 15 drives the gear 14 to rotate in the opposite direction in the third rotating groove 13, so that the gear 14 drives the gear ring 12 to rotate in the opposite direction in the second rotating groove 10, so that the gear ring 12 drives the bevel gear ring 11 to rotate in the opposite direction in the second rotating groove 10. When the bevel gear ring... When the bevel ring 11 rotates in the reverse direction, it drives multiple bevel gears 9 to rotate in the reverse direction within multiple first rotating grooves 8. One end of each bevel gear 9 drives multiple first threaded rods 7 to rotate in the reverse direction within multiple sliding grooves 5. When the multiple first threaded rods 7 rotate in the reverse direction, multiple inserts 6 are acted upon by the threads of the multiple first threaded rods 7, moving away from each other along the multiple sliding grooves 5. When the multiple inserts 6 are moved to a suitable position, one end of each insert 6 inserts into the inner wall of the slot 3 from within the multiple sliding grooves 5, fixing the inner grinding wheel 4 within the slot 3 and preventing it from moving. This ensures that the user can replace the outer grinding wheel 1. Then, the user manually rotates the second rotating rod 21 to... 21 drives one of the sprockets 19 to rotate in the movable groove 18, so that one of the sprockets 19 drives the other sprocket 19 to rotate through the chain 20. When the two sprockets 19 rotate, one end of the two sprockets 19 will drive the two second threaded rods 16 to rotate respectively. When the two second threaded rods 16 rotate, the pressing block 17 will be acted on by the threads of the two second threaded rods 16 and move along the circumference of the first rotating rod 15 toward the inner wheel of the grinding wheel 4. When the pressing block 17 moves to a position where it cannot move, the pressing block 17 will press tightly against the inner wheel of the grinding wheel 4, ensuring that the first rotating rod 15 can be fixed on the inner wheel of the grinding wheel 4 and cannot rotate, preventing the first rotating rod 15 from rotating due to external influences.
