[0003] The patent with the patent announcement number CN217914406U relates to the technical field of stainless steel strip fine grinding equipment, and discloses a fine grinding mechanism for the surface of stainless steel strips, including a base. The right side of the upper end of the base is fixedly connected with a mounting frame. The left side of the upper end of the mounting frame is fixedly installed with a mounting plate. The surface of the mounting plate is provided with a fine grinding assembly. The upper end of the base is fixedly installed with an X-axis linear motor. In this fine grinding mechanism for the surface of stainless steel strips, multiple positioning grooves facilitate the simultaneous placement of multiple strips. The lower ends of the strips are snapped into the positioning grooves, and a telescopic cylinder is used to push the limiting plate to move, clamping and limiting the front and rear sides of the pressure, facilitating the synchronous grinding of multiple strips, improving the processing efficiency. At the same time, the position of the fine grinding disc is adjusted by a Z-axis linear motor, so that the fine grinding disc fits the surface of the strip to achieve fine grinding. During grinding, the dust suction head sucks away the powder generated by grinding, preventing the powder from staying on the surface of the strip and affecting the fine grinding effect, greatly improving the practicability.

The rotation of the rotating rod 9 drives the fine grinding mechanism 10 to rotate, thereby realizing the angle adjustment of the fine grinding mechanism 10. By adjusting the angle, the steel can be better aligned, the angle deviation can be reduced, thereby generating errors and reducing the processing accuracy. Reasonable angle adjustment greatly increases the service life of the fine grinding mechanism 10.

[0021] The fixed plate 3 is provided with a fixed groove 301, the screw rod 5 is fixedly passed through the inner and outer walls of the fixed plate 3, the movable plate 6 is slidably installed inside the fixed groove 301, the rotating rod 9 and the rotating shaft 11 are connected by a transmission belt 12, the screw rod 5 rotates to drive the movable plate 6 to move, and the rotating shaft 11 drives the rotating rod 9 to rotate through the transmission belt 12.

[0022] The circular plate 14 contacts the square block 16 , and the connecting plate 19 is slidably connected with the fixing frame 18 on the side away from the circular plate 14 , pushing the fixing rod 15 to move toward the side close to the fixing frame 18 and driving the circular plate 14 to move.

[0023] During the operation of this embodiment: When fine grinding of steel is required, the motor 4 is started. The output end of the motor 4 rotates to drive the lead screw 5 to rotate. The rotation of the lead screw 5 drives the moving plate 6 to move. The movement of the moving plate 6 drives the fixing mechanism 7 to move. The movement of the fixing mechanism 7 drives the steel to move. The movement of the steel can evenly polish the surface of the steel during fine grinding.

The pressing block 208 is fixedly installed at one end of the fixing mechanism 7 away from the equipment frame 2. The upward movement of the oil inlet frame 204 squeezes the oil inside the oil storage frame 203 and sprays it onto the fine grinding mechanism 10 through the spray oil pipe 206 for lubrication. Lubrication can significantly reduce the friction between the grinding tool and the workpiece, reduce wear. Appropriate lubrication can improve the material removal rate, improve the processing efficiency, and shorten the production time.

[0025] An oil inlet groove 207 is formed on the surface of the oil inlet frame 204. The spray oil pipe 206 is fixedly penetrated through the oil storage frame 203. The side of the L-shaped plate 205 away from the oil inlet frame 204 is set as an inclined plane. The upward movement of the L-shaped plate 205 drives the oil inlet frame 204 to move upward. The upward movement of the oil inlet frame 204 drives the oil storage frame 203 to move upward. At the same time, the upward movement of the oil inlet frame 204 closes the oil inlet groove 207.

[0026] The cleaning device includes a long plate 211, a connecting block 212, a receiving plate 213, a scraping plate 214, a sliding block 215, a bump 216, a baffle 217, a pushing plate 218, a moving block 219 and a stacking frame 210. The long plate 211 is fixedly installed below the oil inlet frame 204. The connecting block 212 is fixedly installed below the long plate 211. The receiving plate 213 is hinged inside the connecting block 212. The scraping plate 214 is slidably installed at the bottom of the fuel tank 202. The sliding block 215 is fixedly installed on the side of the scraping plate 214 close to the L-shaped plate 205. The bump 216 is fixedly installed on the side of the scraping plate 214 away from the sliding block 215. The baffle 217 is fixedly installed inside the fuel tank 202. The pushing plate 218 is slidably installed inside the fuel tank 202. The moving block 219 is slidably installed inside the fuel tank 202. A sliding groove 2112 is opened at the bottom of the fuel tank 202. The stacking frame 210 is fixedly installed below the sliding groove 2112. The scraping plate 214 moves to scrape the impurities accumulated at the bottom of the fuel tank 202. Removing the impurities inside the fuel tank 202 can effectively improve the quality of the oil, ensure the performance of the oil product during use, and enhance the lubrication effect.

[0027] One end of the receiving plate 213 away from the connecting block 121 is hinged to the sliding block 215. The pushing plate 218 is fixedly connected to the moving block 219. The rotation of the receiving plate 213 drives the sliding of the sliding block 215, and the movement of the moving block 219 drives the movement of the pushing plate 218.

[0028] A telescopic spring rod 2111 is fixedly installed on the side of the baffle 217 close to the moving block 219. The telescopic spring rod 2111 is fixedly connected to the moving block 219. When the moving block 219 moves and contacts the telescopic spring rod 2111, the telescopic end of the telescopic spring rod 2111 contracts.

[0029] When the fixing mechanism 7 moves away from the motor 4 and drives the extrusion block 208 to move, the extrusion block 208 moves and contacts the inclined plane of the L-shaped plate 205 and moves upward. The upward movement of the L-shaped plate 205 drives the upward movement of the oil inlet frame 204. The upward movement of the oil inlet frame 204 drives the upward movement of the oil storage frame 203. At the same time, the upward movement of the oil inlet frame 204 closes the oil inlet groove 207. As the extrusion block 208 extrudes the inclined plane of the L-shaped plate 205, the upward movement of the oil inlet frame 204 extrudes the oil inside the oil storage frame 203 to be sprayed onto the fine grinding mechanism 10 through the spray oil pipe 206 for lubrication. Lubrication can significantly reduce the friction between the grinding tool and the workpiece, reduce wear. Appropriate lubrication can improve the material removal rate, improve the processing efficiency, shorten the production time. At the same time, the oil inlet groove 207 is closed when the oil inlet frame 204 moves upward, realizing the quantification of oil spraying. Through quantitative lubrication, it can ensure that the lubricant always remains at a certain level, thereby optimizing the fine grinding conditions, helping to improve the cutting efficiency and processing speed, reducing the processing time, and further improving the overall production efficiency.

[0030] When the oil inlet frame 204 moves downward, it drives the long plate 211 to move downward. The downward movement of the long plate 211 drives the connecting block 212 to move downward. The downward movement of the connecting block 212 drives the receiving plate 213 to rotate. The rotation of the receiving plate 213 drives the sliding block 215 to slide. The movement of the sliding block 215 drives the scraper 214 to move. The movement of the scraper 214 scrapes the impurities accumulated at the bottom of the fuel tank 202. Removing the impurities inside the fuel tank 202 can effectively improve the quality of the oil, ensure the performance of the oil product during use, and enhance the lubrication effect. When the scraper 214 moves to the side away from the L-shaped plate 205, it drives the convex block 216 to move. The movement of the convex block 216 contacts and squeezes the moving block 219 to move. The movement of the moving block 219 contacts the telescopic end of the telescopic spring rod 2111 to contract. The movement of the moving block 219 drives the push plate 218 to move and opens the sliding groove 2112, so that the scraper 214 scrapes the impurities inside the fuel tank 202 into the material storage frame 210, concentrating the impurities in the frame for subsequent cleaning. This can prevent the impurities from flowing back into the fuel tank 202 again and ensure the good operation of the equipment, increasing the service life of the equipment.
