DETAILED DESCRIPTION

[0021] To make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] The present application will be further described below with reference to the embodiments.

[0023] Referring to the drawings Figures 1-9 A continuous casting roller processing polishing device, comprising: a polishing device body 1, used for automatically completing polishing of the surface of the continuous casting roller, the front surface of the polishing device body 1 is slidably connected with a partition 2, one side of the polishing device body 1 is provided with a driving source, further comprising: The utility model relates to a clamping and polishing mechanism 3 for clamping and polishing continuous casting roller end face, the clamping and polishing mechanism 3 includes two groups of polishing clamping ring 31, the surface of two groups of polishing clamping ring 31 is slidably connected with support ring 32 respectively, the outer side of support ring 32 is fixedly connected with several groups of guide plate 33, the outer side of several groups of guide plate 33 is provided with screw nut 34, and screw nut 34 can be slidably connected with guide plate 33, the outer side of screw nut 34 is slidably connected with several groups of telescopic limiting plate 35, and several groups of telescopic limiting plate 35 are fixedly connected with polishing device body 1, the inside of screw nut 34 is threadedly connected with screw 36, and the inside of screw 36 is slidably connected with support ring 32, and the inside of screw 36 is elastically connected with support ring 32 through spring, the outer side of screw 36 is fixedly connected with worm wheel 37, one side of worm wheel 37 is engaged with worm 38, and the top of one group of worm 38 is fixedly connected with driving source, the bottom of worm 38 is engaged with transmission rod 39 through bevel gear, and transmission rod 39 is rotatably connected with the bottom of polishing device body 1, the outer side of support ring 32 is provided with transmission switching assembly 4, is used for controlling the fixed and separated between screw nut 34 and screw 36, realizes work mode switching, the outer side of support ring 32 is provided with sliding switching assembly 5, is used for clamping the surface of continuous casting roller in the polishing process, replaces the fixed function of polishing clamping ring 31, the inside of support ring 32 is provided with support switching assembly 6, is used for switching polishing clamping ring 31 from rigid clamping to elastic pushing state, realizes end face progressive polishing; The drive source can drive the worm 38 to rotate. The worm 38 meshes with the worm wheel 37 to drive the screw 36 to rotate. Since the screw 36 is threadedly engaged with the screw sleeve 34 and the screw sleeve 34 is restricted to sliding by the telescopic limiting plate 35, the screw sleeve 34 will then push the support ring 32 to move through the fixing block 19, the positioning plate 18, and the guide plate 33. The movement of the support ring 32 can push the grinding clamping ring 31 to move and clamp the continuous casting roll. At the same time, the bottom of the worm 38 drives the transmission rod 39 to rotate through the bevel gear, which can realize the synchronous movement of the two sets of screws 36 and ensure that the two sets of grinding clamping rings 31 clamp the two ends of the continuous casting roll synchronously. Then the screw sleeve 34 continues to move. Through the cooperation of the transmission switching component 4, the screw sleeve 34 and the screw 36 can be moved together. Fixed, under the continued transmission of the drive source, the screw sleeve 34 can rotate with the screw 36, and then drive the support ring 32 to rotate through the guide plate 33. The rotation of the support ring 32 can drive the continuous casting roll clamped inside the grinding clamping ring 31 to rotate, so that the grinding device body 1 can grind the surface of the continuous casting roll. During grinding, the two ends of the continuous casting roll surface can be ground first. After the two ends are ground, the transmission switching component 4 can be activated and cooperate with the fixing block 19 and the positioning plate 18, so that the screw 36 can continue to drive the screw sleeve 34 to move. The continued movement of the screw sleeve 34 can push and cooperate with the support plate 53 in the sliding switching component 5, thereby clamping the two ends of the continuous casting roll surface. At the same time, the screw sleeve 34 As it continues to move, it will also drive the telescopic limit plate 35 to move, ensuring its limited path during reset movement. When it moves to the appropriate position, the screw sleeve 34 continues to be fixed to the screw 36 through the transmission switching component 4. Subsequently, the grinding clamping ring 31 no longer clamps and fixes both ends of the continuous casting roll. When the screw sleeve 34 pushes the support plate 53 to move, it can cooperate with the support switching component 6 to switch the grinding clamping ring 31 from the clamping state of both ends of the continuous casting roll to the elastic pushing state. After that, the screw sleeve 34 continues to drive the support ring 32 and the grinding clamping ring 31 to rotate through the guide plate 33. Under the switching action of the support switching component 6, the grinding clamping ring 31 can continuously and progressively grind both ends of the continuous casting roll, while... Plate 2 can protect the grinding area, and finally achieve the grinding of the continuous casting roll body and end face, effectively avoiding the problem of subsequent end face grinding required by traditional devices, and significantly improving grinding efficiency. It is worth noting that the driving source is existing technology, such as a motor, and is fixed inside the grinding device body 1 through existing support frames to maintain a stable driving state. It is worth noting that the telescopic limit plate 35 has a built-in spring, which can follow the screw sleeve 34 to reset when it resets. It is worth noting that the telescopic limit plate 35 has a fixed part and a sliding part inside, which are connected by a spring. When the screw sleeve 34 moves to a specific position, it can push the sliding part to move, thereby providing conditions for the operation of subsequent components. The inner part of the guide plate 33 is slidably connected with the positioning block 7, and the positioning block 7 is magnetically repelled by the electromagnetic block 41, and the positioning block 7 is elastically connected with the guide plate 33 through a spring, and the outer side of the positioning block 7 is insertably connected with the telescopic limiting plate 35; the positioning block 7 in the inner part of the guide plate 33 is elastically connected with the guide plate 33 through a spring, and the positioning block 7 is arranged in magnetic repulsion with the electromagnetic block 41; when the electromagnetic block 41 is not powered, the elastic force of the spring can maintain the positioning block 7 in the initial position, at this time, the guide plate 33 can normally rotate with the screw sleeve 34 and will not be interfered by the positioning block 7; when the electromagnetic block 41 is powered to generate repulsion, it will push the positioning block 7 to slide outward, so that the positioning block 7 is insertably connected with the telescopic limiting plate 35, at this time, the positioning block 7 will limit the guide plate 33, so that the screw sleeve 34 can be driven to move by the screw rod 36 under the limitation of the guide plate 33; when the grinding work is completed, the electromagnetic block 41 will be restarted to push the positioning block 7 to insert with the telescopic limiting plate 35 again, so that the guide plate 33 is fixed, at this time, the driving source can be started to reverse to start the reset movement; With reference to the drawings Figures 2-5The transmission switching assembly 4 includes an electromagnetic block 41, which is existing technology. The electromagnetic block 41 is fixedly connected to the outer side of the support ring 32. A movable ring 42 is magnetically repelled on the outer side of the electromagnetic block 41. A connecting groove 43 is provided on the inner side of the screw 36, and the interior of the connecting groove 43 is slidably connected to the movable ring 42. The interior of the connecting groove 43 is elastically connected to the movable ring 42 by a spring. Two sets of pushing blocks 44 are fixedly connected to the surface of the movable ring 42. A plug-in block 45 is slidably connected to one side of the two sets of pushing blocks 44. The inner side of the plug-in block 45 is elastically connected to the interior of the connecting groove 43 by a spring. The outer side of the plug-in block 45 passes through the screw 36 and extends to the screw. On the outer side of screw 36, a slot is provided on the inner side of screw sleeve 34, and the inside of the slot can be inserted into the plug block 45. The outer side of plug block 45 is inclined. A micro switch 46 is fixedly connected to the top of screw 36, and the micro switch 46 is electrically connected to electromagnetic block 41 through a wire. When screw 36 is driven, it will drive screw sleeve 34 to move. When screw sleeve 34 moves to the appropriate position, it will first push plug block 45 to press inward. After it moves to the appropriate position, spring will push plug block 45 to move outward and insert into the slot on the inner side of screw sleeve 34, thereby fixing screw sleeve 34 and screw 36. At this time, screw sleeve 34 can rotate synchronously with screw 36 and be driven by guide plate 33. The moving support ring 32 and its connecting parts rotate together. When the grinding of both ends of the continuous casting roll surface is completed and it is necessary to release its end face clamping for further grinding, the electromagnetic block 41 can be activated. After being energized, the electromagnetic block 41 will generate a magnetic repulsion force on its outer moving ring 42, causing the moving ring 42 to slide in the connecting groove 43. The pushing block 44 on the surface of the moving ring 42 will also move accordingly and will no longer press the insertion block 45, causing the insertion block 45 to move inward under the action of the spring and separate from the screw 36, thereby realizing the separation of the screw sleeve 34 from the screw 36. Subsequently, due to the insertion of the subsequent positioning block 7 and the telescopic limiting plate 35, the guide plate 33 is limited, and the screw sleeve 34 will continue to be limited under the limiting action of the guide plate 33. After the movement, the electromagnetic block 41 closes, causing the plug-in block 45 to be pushed out by the block 44 again. The screw sleeve 34 can be re-inserted and fixed by the plug-in block 45 on the other side, thereby driving the support ring 32 and its connecting parts to rotate again. The micro switch 46 at the top of the screw 36 is electrically connected to the electromagnetic block 41 through a wire. It can be triggered after the screw sleeve 34 is reset and moved to the appropriate position. After being triggered, the micro switch 46 will close the electromagnetic block 41, so that it no longer magnetically attracts the moving ring 42, nor magnetically repels the subsequent positioning block 7, so that they are automatically reset. It is worth noting that the electromagnetic block 41 is existing technology and has a built-in timer module, which can be turned off at a time after startup to meet the usage requirements. The top of the electromagnetic block 41 is magnetically connected with the positioning plate 18, the positioning plate 18 is slidably connected with the inner part of the guide plate 33, and the positioning plate 18 is elastically connected with the inner part of the guide plate 33 through a spring, the top of the positioning plate 18 is inserted with the fixing block 19 through an inserting plate, the fixing block 19 is slidably connected with the inner part of the guide plate 33, and the fixing block 19 is elastically connected with the inner part of the guide plate 33 through a spring, it is worth noting that the positioning plate 18 is a composite component, which not only includes a magnetic moving part that can be driven by the magnetic force of the electromagnetic block 41 and reset by the spring after power-off, but also includes a positioning part that is slidably connected with the guide plate 33, the positioning part will follow the magnetic moving part to link to switch the fixing block 19 between the active and fixed states, it is worth noting that the fixing block 19 is composed of a fixing part and a supporting part; its working state depends on whether the positioning plate 18 locks it: when the fixing part is locked by the positioning plate 18, the screw sleeve 34 can drive the entire guide plate 33 to move by pushing the fixing block 19; when the fixing part is in a free state, the screw sleeve 34 can only push the fixing block 19 to move independently in the fixing block 19, so as to realize the sliding of the screw sleeve 34 relative to the guide plate 33; in normal state, the fixing block 19 in the inner part of the guide plate 33 is elastically connected with the guide plate 33 through its own spring, and the bottom of the fixing block 19 is inserted with the positioning plate 18 through an inserting plate; the positioning plate 18 is also located in the inner part of the guide plate 33 and connected with the guide plate 33 through a spring, the spring force of the spring will always keep the positioning plate 18 in a position supporting the fixing block 19, so that the fixing block 19 can be stably pushed by the screw sleeve 34 when it is moved for the first time, after the fixing block 19 is pushed, it drives the guide plate 33 to move synchronously, the guide plate 33 further drives the supporting ring 32 and the grinding clamping ring 31 to move towards the continuous casting roller, and finally provides complete power transmission for the preliminary clamping and positioning of the continuous casting roller; when the screw sleeve 34 needs to be moved for the second time, the electromagnetic block 41 is powered and generates a magnetic attractive force, the attractive force pulls the positioning plate 18 to slide downward in the inner part of the guide plate 33 against the elastic force of the spring of the positioning plate 18, after the positioning plate 18 slides downward, the inserting plate between the top of the positioning plate 18 and the fixing block 19 is separated, and the positioning plate 18 no longer supports and limits the fixing block 19; at this time, the fixing block 19 is still affected by the elastic force of its own spring, but after losing the support of the positioning plate 18, it can only slide in the inner part of the guide plate 33 independently under the second pushing of the screw sleeve 34, and cannot drive the guide plate 33 to move, it is worth noting that at this time, the supporting ring 32 and the grinding clamping ring 31 are still in the clamping state of the continuous casting roller, and these two components cannot move by themselves; the movement of the fixing block 19 alone without driving the guide plate 33 to move can also avoid pushing the supporting ring 32 and the grinding clamping ring 31 when the screw sleeve 34 is moved for the second time; Refer to the attached drawings Figures 2-6The sliding switching assembly 5 comprises a plurality of fixed boxes 51, the plurality of fixed boxes 51 are rotationally connected to the outer side of the supporting ring 32, cavities are formed in the plurality of fixed boxes 51, extrusion rings 52 are slidably connected in the cavities, supporting plates 53 are slidably connected to the inner side of the fixed boxes 51, the supporting plates 53 are fixedly connected with the extrusion rings 52 through connecting rods, the supporting ring 32 is connected with the cavities through a hose, moving plates 54 are slidably connected to the inner side of the supporting plates 53, anti-skid clamping blocks 55 are fixedly connected to the inner side of the moving plates 54 through connecting rods, a pushing plate 56 is fixedly connected to the surface of the screw sleeve 34, the pushing plate 56 can push the supporting plate 53, the supporting plate 53 is elastically connected to the inner side of the fixed box 51 through a spring, and the fixed box 51 is fixedly connected with the polishing device body 1 through a sliding guide plate; when the screw sleeve 34 moves towards the continuous casting roller, the pushing plate 56 on the surface of the screw sleeve 34 will be in contact with the supporting plate 53 and push the supporting plate 53 to move towards the continuous casting roller at the same time; the supporting plate 53 drives the extrusion ring 52 to slide in the cavity of the fixed box 51 through the connecting rod, the supporting ring 32 is connected with the cavity through the hose, the extrusion ring 52 will transport the hydraulic oil in the cavity to the inside of the supporting plate 53 through the hose when the extrusion ring 52 slides, the hydraulic oil will push the moving plate 54 in the inside of the supporting plate 53 to move after entering the inside of the supporting plate 53, the moving plate 54 will push the anti-skid clamping block 55 to extend towards the continuous casting roller through the connecting rod on the inner side, so that the surface of the continuous casting roller is clamped and fixed, when the screw sleeve 34 moves reversely and the pushing plate 56 is separated from the supporting plate 53, the spring between the supporting plate 53 and the fixed box 51 will release the elastic force and push the supporting plate 53 to reset to the initial position, so that the device is prepared for the next clamping action; in addition, the fixed box 51 and the supporting ring 32 are rotationally connected, so that the fixed box 51 can avoid interfering with the rotating action of the supporting ring 32 and ensure that the supporting ring 32 can normally drive the related parts for polishing to rotate; it should be noted that the connection positions of all liquid flow paths are sealed by sealing structures to prevent leakage and form a reliable dynamic or static sealing system, so that the liquid leakage phenomenon is effectively eliminated and the pressure stability and energy transmission efficiency of the energy storage system are ensured; it should be noted that, in order to ensure the stability of the trajectory and posture of the fixed box 51 during sliding, the fixed box 51 can be constrained by the existing supporting limiting structure; specifically, the structure can be composed of a plurality of parallel linear guides (or guide keys) and matched sliding blocks (or key grooves) (not shown in the figure), so that the fixed box 51 is limited to a certain movement track and freely slides on the track, and stable operation is ensured when the fixed box 51 clamps the continuous casting roller; The inner side of the support plate 53 is communicated with a breather valve 8, and the breather valve 8 is located in the inner side of the moving plate 54, and the support plate 53 is fixedly connected through reinforcing blocks; the breather valve 8 in the inner side of the support plate 53 is located in the inner side of the moving plate 54, which adjusts the air pressure in the support plate 53, provides air pressure balance for hydraulic oil flow and component reset, and when the support plate 53 is reset to the initial position under the action of the spring, the connecting rod pushes the extrusion ring 52 to reset synchronously in the cavity of the fixed box 51; the extrusion ring 52 generates a suction force in the cavity during the reset process, and the suction force is transmitted to the inside of the support plate 53 through the hose, so that the hydraulic oil in the support plate 53 is sucked back into the cavity, at the same time, the breather valve 8 will transport air to the inner side of the moving plate 54 in the support plate 53, the entering air will form a thrust force on the moving plate 54, assisting the moving plate 54 to move to the initial position, thereby ensuring that the hydraulic oil can flow back smoothly, completing the reset of the entire hydraulic system and preparing for the next clamping action of the device, and at the same time, the moving plate 54 is conveniently reset by the connecting rod to drive the anti-skid block 55, the breather valve 8 is prior art;

the worm 38 drives the impeller in the air suction box 12 to rotate synchronously during rotation, the rotation of the impeller generates negative pressure, so that the air suction grooves 9 in the inner side of the support plate 53 can adsorb the debris generated during polishing, and the debris enters the filter box 11 through the hose for filtration; the clean air filtered is introduced into the air suction box 12 through the pipeline, and then discharged from the air outlet groove 10, thereby increasing the air flow density around the polishing clamping ring 31, and under the suction action of the air suction groove 9, the air is more easily sucked, thereby forming effective circulation, which can effectively collect polishing debris and keep the polishing environment clean, and can also dissipate heat in the polishing area; the air suction groove 9 and the air outlet groove 10 are staggered, so that the discharged clean air and the suctioned air containing debris do not interfere with each other, the debris collection efficiency is ensured, and the power of the entire debris collection system comes from the worm 38, without the need for additional driving devices, thereby saving the energy consumption of the device; a plurality of groups of filter plates 13 are detachably connected in the filter box 11, the bottom of the filter box 11 is arranged in an inclined manner, the bottom of the filter box 11 is communicated with a collection column 14 through a one-way valve, the inside of the collection column 14 is slidably connected with a filter column 15, the top of the inside of the collection column 14 is fixedly connected with a scraping ring 16, and the inside of the filter column 15 is slidably connected with the scraping ring 16; the plurality of groups of filter plates 13 in the filter box 11 can perform multi-layer filtration on the suctioned air containing debris, sufficiently intercept debris of different particle sizes, and ensure the cleanliness of the finally discharged air;And the filter plate 13 is detachable, and can be directly removed for cleaning or replacement in the later period, so that the maintenance operation is more convenient. The bottom of the filter box 11 is inclined, and when the screw sleeve 34 needs to be reset, the impeller of the air suction box 12 connected with the worm 38 also reversely rotates synchronously, and blows air to the inside of the filter box 11; the air can reversely flush the plurality of filter plates 13, and the impurities attached to the filter plates 13 are washed down, and then enter the collecting column 14 through the one-way valve at the bottom of the filter box 11. The inclined bottom of the box can also assist the filtered debris to slide to the collecting column 14 under the action of gravity, so that the debris is prevented from being accumulated and blocked in the filter box 11. The filter column 15 in the collecting column 14 can filter and collect the entering debris. The scraping ring 16 at the top of the collecting column 14 is in sliding connection with the filter column 15. When the exposed part of the filter column 15 is blocked by the debris, the filter column 15 moves downward under the action of air pressure, and the unblocked part continues to work, and the scraping ring 16 can scrape the debris attached to the inside of the filter column 15 during the movement of the filter column 15, so that the filter column 15 is prevented from being blocked, and the collecting column 14 is kept unobstructed, so that the debris can be collected and treated in a centralized manner. With reference to the accompanying drawings Figures 2-7 The support switching assembly 6 comprises a positioning ring 61, and the positioning ring 61 is elastically connected with the polishing clamping ring 31 through a spring. An inner part of the support ring 32 is provided with a storage groove 62, and the storage groove 62 is in sliding connection with the positioning ring 61. The storage groove 62 is in communication with a storage ring 63 through a hose, and the storage ring 63 is fixedly connected with the inner part of the support ring 32. The storage ring 63 is in sliding connection with a switching ring 64, and the switching ring 64 is fixedly connected with a connecting ring 65 on the outer side through a movable rod, and the connecting ring 65 is located on the inner side of the screw sleeve 34. When the screw sleeve 34 moves, the connecting ring 65 on the inner side is pushed to move, the connecting ring 65 pushes the switching ring 64 to slide in the storage ring 63 through the movable rod, the sliding of the switching ring 64 can generate suction force, and the hydraulic oil in the storage groove 62 can be sucked, and the positioning ring 61 is pushed by the spring, so that the positioning block 7 slides and moves in the storage groove 62 and pushes the hydraulic oil. The positioning ring 61 is elastically connected with the polishing clamping ring 31 through a spring and is fixed with the polishing clamping ring 31 through the telescopic rod. The movement of the positioning ring 61 can drive the polishing clamping ring 31 to switch from the rigid clamping state of the continuous casting roller to the elastic pushing state. The state switching can enable the polishing clamping ring 31 to continuously polish the end face of the continuous casting roller in a progressive manner during the rotation, so that the end face is prevented from being unevenly polished due to too tight clamping, and the polishing quality of the end face of the continuous casting roller is ensured. The inner side of the polishing clamping ring 31 is provided with a plurality of groups of flow grooves 17, and the outer side of the polishing clamping ring 31 is fixedly connected with the positioning ring 61 through the telescopic rod; the plurality of groups of flow grooves 17 provided on the inner side of the polishing clamping ring 31 can smoothly flow the debris or cooling medium generated in the polishing process, which can not only assist in removing the heat generated in the polishing process to prevent the polishing clamping ring 31 and the continuous casting roller from being damaged due to high temperature, but also can avoid the accumulation of debris between the polishing clamping ring 31 and the continuous casting roller, which affects the polishing effect; the outer side of the polishing clamping ring 31 is fixedly connected with the positioning ring 61 through the telescopic rod, and the telescopic rod can provide guidance for the movement of the polishing clamping ring 31, so as to ensure that the polishing clamping ring 31 always moves in a straight line when the positioning ring 61 pushes the polishing clamping ring 31, and to avoid deviation; It is worth noting that the transmission members (such as the screw rod 36 and the worm wheel 37) in the technical solution are all connected, fixed and protected through existing standard support structures such as bearing seats and shaft sleeves (not shown in the figure) to ensure the stability and reliability of the transmission process. It is worth noting that the connection of all gas flow paths is sealed by a sealing structure to prevent leakage and form a reliable dynamic or static sealing system to effectively prevent gas leakage and ensure the normal use of the gas and liquid systems.

[0024] Working principle: when the continuous casting roller machining and polishing device is used, first, the driving source on one side of the polishing device body 1 is started, which drives a group of worm gears 38 fixed thereto to rotate. The worm gears 38 drive the screw rods 36 to rotate through the meshing with the worm wheels 37 on one side, and drive the transmission rods 39 to rotate through the bevel gears on the other side, which further drive the other group of worm gears 38 and the corresponding screw rods 36 to move synchronously, so as to ensure that the two groups of polishing clamping rings 31 can move synchronously towards the continuous casting roller. Since the screw rod 36 is threadedly connected with the screw sleeve 34, and the screw sleeve 34 is limited by the outer telescopic limiting plate 35 and cannot rotate, the screw rod 36 rotates to push the screw sleeve 34 to slide along the telescopic limiting plate 35. The screw sleeve 34 slides to move the support ring 32 and its connecting components through the fixed block 19 cooperating with the positioning plate 18 and the guide plate 33. The support ring 32 further pushes the two groups of polishing clamping rings 31 to approach and clamp the continuous casting roller at both ends, so as to realize the preliminary positioning and fixing of the continuous casting roller. After the screw sleeve 34 moves to the appropriate position, it is separated from the telescopic limiting plate 35 and is connected with the guide plate 33 in a sliding manner. It is worth noting that when the polishing clamping ring 31 contacts the continuous casting roller, the polishing clamping ring 31 can move the positioning ring 61 through the telescopic rod to push the hydraulic oil in the storage tank 62 to move. The hydraulic oil is delivered to the inside of the storage ring 63 through the hose for storage, so that the polishing clamping ring 31 rigidly clamps the continuous casting roller; When the screw sleeve 34 moves to the appropriate position, it will extrude and push the plug-in block 45, so that the plug-in block 45 compresses and pushes the push block 44 and the spring connected thereto to shrink. When the screw sleeve 34 continues to move to the appropriate position, the push block 44 is pushed by the spring pushing force to extrude the plug-in block 45, so that the plug-in block 45 is pushed out to the outside and inserted into the insertion slot, so that the screw sleeve 34 is fixed with the screw rod 36. At this time, the screw sleeve 34 can rotate synchronously with the screw rod 36. The screw sleeve 34 rotates through the guide plate 33 to drive the supporting ring 32 to rotate, and the supporting ring 32 drives the polishing clamping ring 31 and the continuously cast roller clamped thereby to rotate. The polishing device body 1 can polish the surface of the continuously cast roller, and preferentially polishes the two end regions of the surface of the continuously cast roller. When the polishing of the two ends of the surface of the continuously cast roller is completed and it is necessary to switch to end face polishing, the electromagnetic block 41 in the clamping and polishing mechanism 3 is started. After the electromagnetic block 41 is electrified, a magnetic repulsion force is generated to push the moving ring 42 to slide. The push block 44 on the moving ring 42 moves and no longer extrudes the plug-in block 45. The plug-in block 45 shrinks to the inside under the action of the spring and is separated from the insertion slot, so that the screw sleeve 34 is separated from the screw rod 36. At the same time, the repulsion force of the electromagnetic block 41 also pushes the positioning block 7 inside the guide plate 33 to slide to the outside. The positioning block 7 is inserted into the telescopic limiting plate 35 to limit the guide plate 33. When the electromagnetic block 41 is started, a magnetic attraction force is also generated to the positioning plate 18, so that the positioning plate 18 moves downward, and the positioning plate 18 no longer supports and positions the bottom of the fixed block 19. At this time, the screw sleeve 34 can only push the fixed block 19 to move when moving, and cannot push the guide plate 33 to move. Subsequently, the screw rod 36 continues to rotate to push the screw sleeve 34 to move along the guide plate 33 to the continuously cast roller. The push plate 56 on the surface of the screw sleeve 34 will contact the supporting plate 53 in the sliding switching assembly 5 and push the supporting plate 53 to move. The supporting plate 53 drives the extrusion ring 52 in the cavity of the fixed box 51 to slide through the connecting rod. The extrusion ring 52 delivers hydraulic oil in the cavity to the inside of the supporting plate 53 through the hose. The hydraulic oil pushes the moving plate 54 to move. The moving plate 54 drives the anti-slip clamping block 55 to extend and clamp the surface of the continuously cast roller through the connecting rod, so as to replace the polishing clamping ring 31 to stably fix the continuously cast roller. Meanwhile, the movement of the screw sleeve 34 also pushes the inner connecting ring 65, which drives the switching ring 64 in the storage ring 63 in the support switching assembly 6 to slide through the movable rod, and the suction force generated by the sliding of the switching ring 64 makes the hydraulic oil in the internal storage groove 62 of the support ring 32 flow into the storage ring 63 through the hose, the positioning ring 61 slides along the storage groove 62 under the action of the spring, and the polishing clamping ring 31 is driven by the telescopic rod to switch from the rigid clamping state to the elastic pushing state of the continuous casting roller, then the electromagnetic block 41 is closed under the action of the timing module, the positioning block 7 is reset and separated from the telescopic limiting plate 35 under the action of its connecting spring, the moving ring 42 is reset under the action of the spring, the pushing block 44 re-presses the plug-in block 45, the plug-in block 45 pops out and is inserted into the slot on the other side of the screw sleeve 34, so that the screw sleeve 34 is fixed with the screw rod 36 again and rotates with it, the screw sleeve 34 rotates to drive the support ring 32 and the polishing clamping ring 31 to rotate, and the polishing clamping ring 31 in the elastic pushing state can progressively polish the end face of the continuous casting roller, ensuring the uniformity and integrity of the end face polishing; and during the entire polishing process, the rotation of the worm 38 also drives the impeller in the air suction box 12 to rotate, and the negative pressure generated by the impeller makes the air suction groove 9 in the support plate 53 adsorb the polishing debris through the hose, the debris is sucked into the filter box 11 and then filtered by the internal multiple filter plates 13, the clean air after filtration enters the air suction box 12 through the pipeline, and then is transported to the air outlet groove 10 of the support plate 53 from the air suction box 12 through the hose and is discharged, forming air circulation, which can not only collect debris but also cool the polishing area, and the bottom of the filter box 11 is inclinedly arranged; When the surface and end face of the continuous casting roller are polished, the electromagnetic block 41 is started again, the electromagnetic block 41 pushes the positioning block 7 to insert and fix the guide plate 33 with the telescopic limiting plate 35, then the driving source is reversed, the driving source drives the worm 38 and the screw rod 36 to rotate reversely, the screw rod 36 reversely rotates to make the screw sleeve 34 start to reset and move, the worm 38 reversely rotates to drive the impeller to reverse, the reverse airflow flushes the impurities on the filter plate 13, the impurities enter the collection column 14 through the one-way valve along the inclined bottom of the box, the filter column 15 in the collection column 14 can intercept the impurities, and when the filter column 15 moves downward under the action of the airflow pressure, the scraper ring 16 scrapes the debris inside the filter column 15, ensuring the smoothness of the collection column 14, the pushing plate 56 no longer pushes and fixes the support plate 53 during the resetting of the screw sleeve 34, the support plate 53 resets under the action of the spring, the pressing ring 52 resets with the support plate 53 and draws the hydraulic oil in the support plate 53 back to the cavity of the fixing box 51 through the hose, the air valve 8 transports air into the support plate 53 to assist the resetting of the moving plate 54 and the anti-slip clamping block 55, when the screw sleeve 34 resets to the initial position, the micro switch 46 at the top of the screw rod 36 is triggered, the micro switch 46 closes the electromagnetic block 41, the positioning block 7 separates from the telescopic limiting plate 35 under the action of the spring, and the guide plate 33 restores the rotatable state, at this time, the polishing clamping ring 31 can be loosened to take out the polished continuous casting roller, and the entire polishing operation process is completed.
