Description

Technical Field

[0001] The present invention relates to the technical field of grinding wheel processing devices, and particularly to a diamond roller dressing device. Background Art

[0002] As a key component in grinding processing, grinding wheels are widely used in fields such as mechanical manufacturing and the automotive industry. The grinding wheel cuts, grinds, and polishes the workpiece through a large number of abrasive grains on its surface, and its shape accuracy and surface quality directly affect the accuracy and surface finish of the machined workpiece. However, during long-term use, the abrasive grains on the surface of the grinding wheel will gradually wear and become dull, resulting in a decrease in the cutting ability of the grinding wheel. Therefore, regular dressing of the grinding wheel is a necessary means to ensure its processing performance.

[0003] In the prior art, diamond roller dressing technology has been widely used in grinding wheel dressing processing due to its high precision and high efficiency. The diamond roller is made of high-hardness diamond particles and a metal binder, and can quickly and accurately remove the dull abrasive grains on the surface of the grinding wheel, restoring the geometric shape and sharpness of the grinding wheel. Compared with traditional dressing tools, diamond roller dressing has significant advantages such as fast dressing speed, high dressing accuracy, and long service life, and is particularly suitable for large-batch and high-precision grinding processing scenarios.

[0004] During the actual processing, due to the high-speed friction between the diamond roller and the grinding wheel, a large amount of heat is easily generated on the surface of the diamond roller. Generally, cooling means are used to cool it to prevent thermal damage and thermal deformation, and to flush away the grinding debris to avoid clogging. Since there are chip pockets on the diamond roller and it is difficult to clean the grinding debris remaining therein, cleaning materials are also used to assist in cleaning the chip pockets. However, the positions of the chip pockets on different diamond rollers are different, resulting in the difficulty of comprehensively cleaning the chip pockets with conventional cleaning materials, and the remaining grinding debris will affect the dressing quality of the grinding wheel.

[0032] Rotate the fixing nut 8 and remove it from the loading shaft 6. Install the diamond roller 27 on the left loading shaft 6 and the grinding wheel 28 on the right loading shaft 6 respectively. Then, install the fixing nut 8 back on the loading shaft 6 and reverse the fixing nut 8 to stably fix the diamond roller 27 and the grinding wheel 28 on the two loading shafts 6. Start the motor 10. Through the transmission between the connecting shaft 19 and the universal shaft 18 and the transmission between the synchronous pulley 20 and the synchronous toothed belt 21, control the rotation of the two loading shafts 6. Set a speed difference between the two synchronous pulleys 20 between the two loading shafts 6, and control the rotational speed of the left loading shaft 6 to be greater than that of the right loading shaft 6, that is, control the rotational speed of the diamond roller 27 to be greater than that of the grinding wheel 28. By increasing the friction force of the diamond roller 27 on the grinding wheel 28, improve the dressing effect of the diamond roller 27 on the grinding wheel 28. Start the electric cylinder 9, control the moving block 5 to move to the left, control the grinding wheel 28 to move towards the diamond roller 27, and perform dressing processing on the grinding wheel 28. During the process, the moving block 5 controls the top plate 14 to move downward, and the transmission control processing part 12 rotates towards the diamond roller 27, so that the soft belt 1204 contacts the diamond roller 27, and the first spring 1208 is compressed. The soft belt 1204 and the cleaning block 1205 thereon corresponding to the chip groove position on the diamond roller 27 can be inserted into the chip groove to achieve adaptive adjustment with the diamond roller 27. At the same time, the sealing plate 24 opens the channel between the connecting pipe 11 and the delivery pipe 23, so that the coolant can flow in the connecting pipe 11 and the delivery pipe 23, and the pump body in the liquid tank 22 automatically opens. Therefore, the nozzle 1202 can spray the coolant onto the diamond roller 27 and the grinding wheel 28 to cool them, reduce high-temperature damage, and the electric roller 1203 rotates to control the cleaning block 1205 to clean the residual grinding chips in the chip groove, improving the dressing quality of the diamond roller 27 on the grinding wheel 28. By bringing the processing part 12 close to the diamond roller 27, the coolant can be sprayed onto the diamond roller 27 at a short distance, thereby reducing the splashing distance of the coolant by the diamond roller 27 and keeping the use environment clean. And not directly setting the processing part 12 near the loading shaft 6 is to avoid the position of the processing part 12 affecting the installation of the grinding wheel 28 for easy operation. Finally, after completing the dressing processing of the grinding wheel 28, turn off the motor 10, control the grinding wheel 28 and the diamond roller 27 to stop rotating, and the electric cylinder 9 controls the moving block 5, the right loading shaft 6 and the grinding wheel 28 to move to the right. The moving block 5 disengages from the top plate 14, and the second spring 15 resets the top plate 14 upward, and controls the connecting pipe 11 and the processing part 12 to reverse. At this time, the sealing plate 24 closes the channel between the connecting pipe 11 and the delivery pipe 23, and the pump body in the liquid tank 22 automatically closes. In this way, a complete dressing processing flow of one grinding wheel 28 is completed, and then the next grinding wheel 28 can be replaced for dressing. After the coolant is sprayed onto the diamond roller 27, while cooling the diamond roller 27, it will also carry away the chips generated when the diamond roller 27 dresses the grinding wheel 28, reducing the influence of the chips on the dressing processing;Subsequently, the coolant drives the debris to fall, and the filter screen 25 separates the coolant and the debris for subsequent separate treatment of the two; finally, the plug plate 26 is opened to discharge the coolant, and after the discharge is completed, the debris can be cleared along the inclined filter screen 25.;

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
