Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of polishing, in particular to a polishing device and method for high-precision mirror roller. BACKGROUND

[0002] The polishing of high-precision mirror roller needs to be realized through a multi-stage process, precise equipment control and strict environmental management, and usually includes three stages of rough polishing, medium polishing and fine polishing.

[0003] In the rough polishing stage, a wet sand belt polisher is used to perform preliminary polishing with 250-mesh sand belt to remove the micro-distinguishable machining marks on the surface of the roller body. The surface of the roller body after rough polishing is a dark luster surface, but there may be continuous radial grooves. In the medium polishing stage, 500-mesh and 1000-mesh sand belts are used in turn to polish, gradually refining the grooves and reducing surface defects. In the fine polishing stage, 1500-mesh sand belt is used to polish. If the standard is not reached, this step is repeated. Finally, 3000-mesh polishing sand belt is used to basically remove the residual grooves and achieve mirror effect. The key equipment for polishing the roller body includes a polishing machine and sand belts of different mesh numbers. The roller surface also needs to be thoroughly cleaned before polishing. The environment needs to be kept dry and dust-free during polishing to avoid dust and grinding wheel particles adhering to the roller surface, causing scratches or orange peel. When polishing aluminum guide rollers, high-precision stage-by-stage polishing is required. Polishing sand belts of 800-mesh and 1200-mesh are used in turn. Finally, a wool wheel is used in combination with polishing paste to polish the surface of the roller body to mirror effect.

[0004] The wool wheel is a commonly used polishing abrasive material made of high-density wool fibers, which can effectively eliminate shallow scratches on the surface of the roller body and improve gloss. The high density and small porosity of the wool wheel enable it to better retain polishing paste or cooling liquid during polishing, improving polishing efficiency. The wool wheel can quickly remove small scratches and defects on the surface of the workpiece, making the surface of the workpiece achieve mirror effect. However, the polishing effect of the wool wheel gradually decreases with the increase of the use time when it is used for friction polishing of the roller body surface. Therefore, a new wool wheel needs to be replaced regularly to maintain the best polishing effect.

[0005] Currently, the existing technology usually uses a polishing machine in combination with a wool wheel to polish the roller body, making the surface of the roller body achieve mirror effect. The wool wheel is a consumable product. Under normal use, if the wool fibers are observed to be significantly worn or knotted after polishing a certain number of workpieces, the workpiece will lose gloss and the polishing effect will be poor if the wool wheel is continued to be used. Therefore, the wool wheel needs to be replaced immediately. However, the polishing work needs to be frequently paused and the wool wheel needs to be manually replaced, which breaks the continuity of polishing and thus affects the polishing efficiency. Therefore, the existing needs are not met. To this end, the present application provides a polishing device and method for high-precision mirror roller. SUMMARY

[0042] With the above technical solution, the polishing device for the high-precision mirror roller provided in this disclosure, when in use, the motor 130 drives the first gear 140 to rotate. Through the meshing of the first gear 140 and the second gear 160, the second gear 160 drives the first rotating shaft 170 and the polishing wool wheel 180 on it to rotate, so as to perform mirror polishing on the surface of the roller. When the polishing wool wheel 180 is worn, the first electric lifting rod 190 drives the connecting plate 150 to slide, so that the connecting plate 150 drives the second gear 160, the first rotating shaft 170 and the polishing wool wheel 180 away from the first gear 140 and the roller respectively through the fixing rod 151. When the second gear 160 disengages from the first gear 140, the polishing wool wheel 180 stops rotating. The connecting plate 150 drives the first slider 210 to continue sliding within the first groove 221, causing the first slider 210 to abut against the first switch 223, pressing the first switch 223 to disconnect the circuit. This causes the electromagnet 181 to lose its magnetism due to the power outage, releasing the attraction and fixation of the electromagnet 181 on the metal ring 183. At the same time, the electromagnet 181 also loses the repulsive force between the like poles of the magnet 187. Under the action of the rebound force of the first spring 185, the positioning rod 184 retracts into the first rotating shaft 170, releasing the positioning function of the positioning rod 184 on the polishing wool wheel 180. This allows the polishing wool wheel 180 to slide relative to the first rotating shaft 170. Subsequently, the first slider 210 abuts against the baffle 224, and the telescopic rod 200 extends, allowing the first slider 210 to slide along the baffle 224 into the second groove 222. The first slider 210 then abuts against the inclined block 225, pushing the inclined block 225, which in turn moves the connecting rod 226. This causes the connecting rod 226 to push the polishing wool wheel 180, causing the worn polishing wool wheel 180 to fall off the first rotating shaft 170, thus completing the disassembly of the polishing wool wheel 180. While disassembling the worn polishing wool wheel 180, the connecting plate 150 drives the third gear 241 and the second rotating shaft 240 to move synchronously toward the first gear 140. During this approach, the second slider 242 always slides within the corresponding first groove 221. Through the cooperation of the second electric lifting rod 232 and the mounting strip 231, the mounting plate 230 is pushed. At the same time, through the sliding of the protrusion 233 within the inclined groove 2341, the mounting plate 230 drives the straight rod 235 and the spare wool wheel 236 to move closer to the second rotating shaft 240. When the straight rod 235 and the central axis of the second rotating shaft 240 are on the same horizontal line, the protrusion 233 slides within the straight groove 2342, causing the spare wool wheel 236 and the second rotating shaft 240 to move synchronously. At this time, the third electric lifting rod 237 drives the push rod 238, causing the push rod 238 to push the spare wool wheel 236. The spare wool wheel 236 is fitted onto the second rotating shaft 240. Subsequently, the second electric lifting rod 232 drives the mounting plate 230 to reset. The second slider 242 abuts against the corresponding baffle 224, flipping the baffle 224 upward. Then, the second slider 242 presses the second switch 243, which energizes the electromagnet 181 electrically connected to the second switch 242 to generate magnetism that attracts the metal ring 183. At the same time, the electromagnet 181 generates a downward repulsive force on the magnet 187, pressing down the wedge block 186. Through the cooperation of the wedge block 186 and the positioning rod 184, the positioning rod 184 extends outward from the second rotating shaft 240 and abuts against the spare wool wheel 236 to position the spare wool wheel 236, thus fixing the spare wool wheel 236 on the second rotating shaft 240, and the corresponding first spring 185 is compressed. Finally, when the third gear 241 meshes with the first gear 140, the spare wool wheel 236 also comes into contact with the roller surface, causing the first gear 140 to drive the third gear 241 to rotate. The third gear 241 then drives the spare wool wheel 236 to rotate via the second shaft 240, thus allowing the rotating spare wool wheel 236 to continue mirror polishing the roller surface. In summary, this facilitates automatic replacement of the wool wheel during uninterrupted polishing, maintaining the continuity of polishing and thereby improving polishing efficiency.

[0043] It should be noted that when the third gear 241 approaches the first gear 140, if the teeth of the third gear 241 abut against the teeth of the first gear 140, the elastic ring 141 is compressed and undergoes elastic deformation due to the cooperation of the elastic ring 141 and the limiting block 142. When the first gear 140 rotates, the teeth of the first gear 140 move to engage with the tooth groove of the third gear 241. Under the action of the elastic ring 141's rebound force, the first gear 140 moves towards the third gear 241, causing the teeth of the first gear 140 to engage in the tooth groove of the third gear 241, thereby enabling the third gear 241 and the first gear 140 to mesh.
