As shown in fig. 1 to 11, a grinding device of a furnace roller of the present invention includes: the device comprises a machine tool 1, a furnace roller polishing unit 2, a cooling unit 3 for cooling during polishing, and a rotating speed and rotating speed adjusting unit;
The machine tool 1 is also provided with a three-jaw chuck 61 for clamping the furnace roller before polishing; and a linear module 62 for driving the three-jaw chuck 61 to move transversely along the machine tool 1; the furnace roller to be polished is fixedly arranged on the machine tool 1 through the three-jaw chuck 61 before polishing, the furnace roller fixedly arranged on the three-jaw chuck 61 can move back and forth along the lower part of the polishing piece during polishing through the linear module 62, so that the furnace roller is clamped, and the surface of the furnace roller can be polished more comprehensively through the back and forth movement of the linear module 62 during polishing.
As is known in the art, the goal of the rough grinding stage is to quickly remove large irregularities and contaminants, such as nodules, oxides, etc., from the surface of the furnace roller when the furnace roller is being ground; therefore, a higher polishing speed is generally selected during rough polishing to increase the processing speed and improve the efficiency; the higher polishing speed is beneficial to covering a larger polishing area in a short time, so that the overall polishing time is shortened; however, in the finish polishing stage, the aim is to further improve the smoothness and precision of the surface of the furnace roller and remove the fine flaws left in the rough polishing stage; to achieve finer surface treatments, finish sanding typically reduces the sanding speed; the slower polishing speed is beneficial to better controlling the polishing depth and uniformity and ensuring that the required surface quality is achieved;
therefore, as is known from the above common knowledge, the rotation speed of the motor 41 is required to be different when the finish rough grinding is performed on the hearth roll.
The polishing unit 2 includes: a fine polishing member 21, a rough polishing member 22, and a rough polishing member switched by rotation speed; the device consists of a rotating shaft 231, swing balls 232 which are separated in opposite directions according to the rotating speed of the rotating shaft 231, a fixed disc 233 which is separated along with the swing balls 232 and slides on the rotating shaft 231, a hinge piece 234 and a switching component 235 which controls the opposite movement of the thick and thin polishing pieces when the fixed disc 233 slides; the rotating shaft 231 is fixedly connected with the output end of the motor 41; one end of the hinge 234 is fixedly connected with the swing ball 232; the other end of the hinge 234 is hinged with the fixed disk 233; the middle part of the hinge 234 is hinged on the rotation shaft 231; the rotating shaft 231 is provided with a chute 236; the fixed disk 233 is slidably mounted in the chute 236 of the rotating shaft 231; when the fixed furnace roller is subjected to the first step of rough polishing, the motor 41 rotates according to the rough polishing speed, the rotating shaft 231 is fixedly connected with the output end of the motor 41, the motor 41 drives the rotating shaft 231 to rotate, and the middle part of the hinge piece 234 is hinged on the rotating shaft 231, so that when the rotating shaft 231 rotates at a high speed, the swing balls 232 at one end of the hinge piece 234 are separated from each other under the action of centrifugal force, and when one end of the connecting piece is separated from each other along with the swing balls 232, the other end of the hinge rod is also separated by stretching; since the other end of the hinge member 234 is hinged to the fixed disk 233, the hinge disk is slidably mounted on the rotation shaft 231, so that when the swing ball 232 is separated from each other by centrifugal force, the fixed disk 233 slides along the rotation shaft 231 toward the hinge point between the middle of the hinge member 234 and the rotation shaft 231, thereby providing power for the following switching assembly 235.
The switching component 235 includes: a rack one 2351 fixedly mounted on the fixed disk 233; a drive gear 2352 engaged with rack one 2351; the driving gear 2352 is coaxially connected with the driven gear 2353; the upper ends of the fine polishing piece 21 and the rough polishing piece 22 are fixedly connected with a second rack 2354 and a third rack 2355 respectively; the second rack 2354 and the third rack 2355 are respectively symmetrically meshed with the two sides of the driven gear 2353; when the fixed disc 233 slides along the sliding groove towards the hinging point of the middle part of the hinging piece 234 and the rotating shaft 231, the first rack 2351 is fixedly arranged on the fixed disc 233 and moves along the same direction as the fixed disc 233, when the first rack 2351 moves along the same direction as the fixed disc, the driving gear 2352 is simultaneously driven to rotate, and the driving gear 2352 is coaxially and fixedly connected with the driven gear 2353, so that when the driving gear 2352 rotates, the driven gear 2353 rotates successively, when the driven gear 2353 rotates, the second rack 2354 and the third rack 2355 which are symmetrically meshed with the two sides of the driven gear 2353 move reversely, and the second rack 2354 and the third rack 2355 are respectively fixedly connected with the upper ends of the finish polishing piece 21 and the rough polishing piece 22; so that the coarse grinding member 22 and the coarse grinding member 22 can be sequentially switched when the fixed disk 233 drives the rack one 2351 to move along the rotation shaft 231; thereby realizing the switching between the fine polishing and the rough polishing.
Namely, when the polishing piece is required to be polished roughly, the common knowledge proves that the rotation speed of the polishing piece is required to be relatively high; the worker adjusts the motor 41 to a proper range according to experience, and the rotating speed range of the motor 41 for rough grinding is recommended to be 1500-2500 rpm; the rotation speed range of the motor 41 for finish polishing is recommended to be 800-1500 rpm; when the swing ball 232 is fully opened along with the centrifugal force, the required rotating speed is matched with the rotating speed during rough polishing, so that when rough polishing is required, the swing ball 232 can be fully separated and drive the fixed disc 233 to move during rough polishing operation; when the fixed disc 233 moves, the rough grinding elements 22 are accurately moved to the surface of the furnace roller through the switching assembly 235, so that the furnace roller can be subjected to high-efficiency rough grinding;
When the furnace roller is required to be polished after being polished roughly, only the rotating speed of the motor 41 is required to be reduced, the swing balls 232 are not separated under the influence of heavy centrifugal force, the swing balls 232 gather inwards, and the fixed plate is far away from the hinge point direction of the middle part of the hinge piece 234 and the rotating shaft 231 along the sliding groove, so that the fine polishing piece 21 is accurately moved to the surface of the furnace roller through the switching component 235, and the furnace roller is polished efficiently and accurately; therefore, the rough and fine polishing mode can be automatically replaced by controlling the rotating speed of the motor 41, so that the polishing efficiency is remarkably improved, and the polishing effect is ensured to be excellent.
As a further extension of the patent, because the material of the furnace roller is different, and some materials with poor heat conduction effect cannot be rotationally polished at high speed, the furnace roller of each material needs a specific polishing rotating speed to achieve the optimal polishing effect; although the swing ball 232 is separated by setting a specific rotation speed, so as to realize automatic switching of the rough grinding and fine grinding pieces 21, when coping with furnace rollers of different materials, we propose a further optimization scheme; if the furnace rollers made of different materials are polished, only the swing balls 232 with different masses need to be replaced; due to the mass difference of the swing ball 232, the rotating speed for completely opening the swing ball 232 is also different, so that the switching time and the rotating speed of the polishing piece are accurately controlled, and the furnace rollers made of different materials are polished efficiently.
As is known in the art, the primary purpose of the rough grinding stage is to rapidly remove large imperfections and irregularities of the furnace roller surface, thus generally requiring high rotational speeds and high grinding forces; during this process, frictional heat is rapidly generated, and the surface temperature of the furnace roller is significantly increased; in order to effectively reduce the surface temperature and prevent the thermal deformation or other thermal damage of the material, relatively more water spraying amount is needed during rough polishing; a large amount of water can quickly absorb and take away heat, so that the cooling and protecting effects are achieved;
the fine polishing stage pays more attention to the detail treatment of the surface of the furnace roller so as to achieve higher requirements on smoothness and precision; at this stage, the rotation speed and the polishing force are reduced to reduce further damage to the surface of the material; meanwhile, because the friction heat generated in the fine polishing process is relatively less, a large amount of water spraying is not needed like coarse polishing; excessive water spray may affect the friction of the sanding tool, reduce sanding efficiency, and may even leave water marks or cause other adverse effects on the material surface.
The cooling unit 3 includes: a spray head 31, a volume adjusting mechanism for switching the volume of the spray head 31 by the rotating speed; the volume adjusting mechanism consists of a bag body 321, an extrusion piece 322 for extruding the bag body 321, an annular rack 323 for driving the extrusion piece 322 to extrude the bag body 321, and a half gear 324 meshed with the annular rack 323; extrusion 322 is fixedly connected with annular rack 323; the annular rack 323 is mounted on the machine tool 1 housing by a ball slide 325; the liquid inlet end of the capsule 321 is fixedly connected with an external water source through a pipe fitting; the liquid outlet end of the capsule 321 is fixedly connected with the spray head 31 through a pipe fitting, and when the required cooling liquid spraying amount is not required to be very high during fine polishing, uniform spraying is only required to be carried out through the spray head 31 by an external water source; when coarse polishing is performed, the required spraying amount of the cooling liquid is very high; therefore, the half gear 324 is driven to rotate, the half gear 324 is meshed with the annular rack 323, the annular rack 323 is driven to reciprocate when the half gear 324 rotates, and the extrusion piece 322 is fixedly connected with the annular rack 323, so that when the annular rack 323 reciprocates, the extrusion piece 322 also reciprocates, the bag body 321 is extruded, the water originally flows to the spray head 31 from an external water source smoothly, and the flow and the pressure of water are enhanced due to continuous compression and resetting of the air bag, so that the effective regulation of the water flow is realized; in the rough polishing stage, the adjusting mechanism can automatically adjust the water quantity to be larger so as to meet the requirement on water flow in the rough polishing process.
The half gear 324 is driven to rotate after the fixed disk 233 moves to the fixed position; a follower rod 51 slidably mounted on the machine tool 1, a transmission rod 53 rotatably mounted on the follower rod 51 through a bearing 52, and a gear II 54 fixedly mounted on one end of the transmission rod 53; the other end of the transmission rod 53 is provided with a bump 55 which is convenient to be abutted with the half gear 324; a fourth rack 56 is fixedly arranged along the edge of the fixed disk 233; the second gear 54 is meshed with the fourth gear 56; a reset spring 57 for driving the follower rod 51 to reset is also arranged between the follower rod 51 and the machine tool 1 shell; the rack IV 56 is fixedly arranged at the edge of the fixed disc 233, and when the motor 41 drives the fixed disc 233 to rotate, the gear II 54 meshed with the rack IV 56 rotates along with the fixed disc 233, and the transmission rod 53 is rotatably arranged on the follow-up rod 51 through the bearing 52 because the gear II 54 is fixedly arranged on the transmission rod 53, so that when the gear II 54 rotates, the transmission rod 53 freely rotates on the follow-up rod 51; when coarse polishing is needed, the fixed disc 233 is separated along with the influence of the centrifugal force of the swing ball 232, and the fixed disc 233 moves relatively along with the centrifugal force, so that the other end of the transmission rod 53 is abutted against the half gear 324 and drives the half gear 324 to rotate; since the follower rod 51 is slidably mounted on the machine tool 1, there is no movement interference caused when the fixed disk 233 moves the transmission rod 53 laterally.
Namely, when the rough grinding is needed, the rotation speed of the motor 41 is regulated, and the fixed disc 233 is pushed by the swing ball 232 under the action of centrifugal force, so that the rough grinding and fine grinding pieces 21 are adaptively switched, the corresponding grinding pieces are tightly attached to the furnace roller, and the grinding pieces rotate around the furnace roller to be ground under the rotation of the motor 41; meanwhile, the half gear 324 is pressed by the moving of the fixed disc 233 during rough polishing, and the rotation of the fixed disc 233 is changed into the transverse movement of the pressing piece 322 by the rotating assembly, so that the cooling liquid spraying amount is increased during rough polishing. In the finish polishing process, the rotation speed can not reach the separation of the swing ball 232, so that the fixed disc 233 is reset, the switching component 235 is pushed to switch to the finish polishing piece 21, and meanwhile, the fixed disc 233 is separated from the half gear 324, so that the cooling liquid spraying amount is not required to be increased.
As a further extension of this patent, the specific method of use of the device when no manual intervention is required is as follows:
the rotation speed adjusting unit comprises an information acquisition end for acquiring the rotation speed of the motor 41, a data processing end for processing the rotation speed of the motor 41 acquired by the information acquisition end, and a control instruction I or a control instruction generating end for generating a control instruction according to the processing result of the data processing end.
The specific steps for generating the first control instruction or the second control instruction are as follows:
Step S1, the data processing end compares the acquired rotating speed of the motor 41 with a preset threshold, and the rotating speed of the motor 41 is high if the rotating speed of the motor 41 is higher than the preset threshold, and is low if the rotating speed of the motor 41 is lower than the preset threshold, and the result is sent to the instruction generating end;
and S2, generating a first control command when the command generating end receives the high rotating speed, and generating a second control command when the command generating end receives the low rotating speed.
The preset threshold comprehensively considers factors such as polishing results and the like, and instructions are set manually according to experience.
