Description

Technical Field

[0001] This invention relates to the field of grinding machines, specifically a high-efficiency electroplated grinding wheel grinding machine and a workpiece grinding method. Background Technology

[0002] A grinding machine is a machine tool that uses a grinding wheel to grind the surface of a workpiece. In current technology, a grinding machine mainly consists of two parts: a grinding wheel grinding mechanism and a guide wheel rotation mechanism. The grinding wheel grinding mechanism drives the grinding wheel to rotate at high speed by a motor to grind the workpiece. The guide wheel rotation mechanism drives the guide wheel to rotate at high speed by a motor. It is located on the other side of the workpiece and supports and guides the workpiece to contact the grinding wheel for grinding.

[0003] In current technology, grinding machines use ordinary resin grinding wheels for grinding. However, because the diamond particles on the grinding wheel are fixed by resin, the surface roughness of the grinding wheel is relatively low, resulting in poor grinding ability of the grinding wheel on the workpiece and long processing time. Therefore, in order to address the above problems, a high-efficiency electroplated grinding wheel grinding machine and workpiece grinding method are proposed. Summary of the Invention

This application replaces the commonly used ordinary diamond grinding wheel in the prior art with the electroplated grinding wheel 19. The diamond abrasive layer is directly deposited on the substrate surface using the electroplating process, which significantly improves the abrasive grain bonding strength, dimensional accuracy and contour retention. Furthermore, the electroplated grinding wheel 19 can greatly improve grinding efficiency and surface grinding consistency. Moreover, the weight of the electroplated grinding wheel 19 is lighter than that of the diamond grinding wheel.

[0021] Furthermore, such as Figures 1-5 As shown, the fixing mechanism includes a chuck 21 and a locking plate 22. The chuck 21 is mounted on the first drive shaft 13. The electroplated grinding wheel 19 is sleeved on the chuck 21 and is located between the chuck 21 and the locking plate 22. The chuck 21 and the locking plate 22 are connected by bolts and press the electroplated grinding wheel 19. The first drive shaft 13 is provided with a tapered part 32.

The guide post 62 drives the dressing cutter 54 to move synchronously, adjusting the distance between the dressing cutter 54 and the surface of the electroplated grinding wheel 19. Then, the hydraulic cylinder 52 drives the support 53 to move. The movement of the support 53 drives the guide post 62 and the dressing cutter 54 to move laterally synchronously, thereby achieving the dressing of the electroplated grinding wheel 19. By setting the aforementioned fixing mechanism, this application can significantly reduce the axial runout generated during the rotation of the electroplating grinding wheel 19.

[0025] Working principle: During use, the workpiece is placed between the guide wheel 14 and the electroplated grinding wheel 19. The first motor 15 drives the first transmission shaft 13 and the electroplated grinding wheel 19 to rotate via a belt. The second motor 191 drives the second transmission shaft 18 and the guide wheel 14 to rotate via a belt. The rotation of the electroplated grinding wheel 19 achieves grinding of the workpiece. The lead screw moving assembly is used to drive the second machine base 17 to move, thereby adjusting the distance between the guide wheel 14 and the electroplated grinding wheel 19. This application replaces the ordinary diamond grinding wheel commonly used in the prior art with the electroplated grinding wheel 19. The diamond abrasive layer is directly deposited on the substrate surface using the electroplating process, which significantly improves the abrasive grain bonding strength, dimensional accuracy and contour retention. Furthermore, the electroplated grinding wheel 19 can greatly improve grinding efficiency and surface grinding consistency. Moreover, the weight of the electroplated grinding wheel 19 is lighter than that of the diamond grinding wheel. During installation, the first drive shaft 13 is provided with a tapered part 32, which is embedded into the corresponding tapered cavity of the chuck 21. Then, the chuck 21 is locked and fixed from the side by rotating the pressure ring 31. The electroplated grinding wheel 19 is then fitted onto the chuck 21, and the chuck 21 and the locking plate 22 are fixed together by bolts. The locking plate 22 presses and fixes the electroplated grinding wheel 19 from the side, thereby locking and fixing the electroplated grinding wheel 19, reducing the axial runout of the electroplated grinding wheel 19 during operation. The precise fit between the tapered part 32 and the tapered cavity of the chuck 21 guides and presses, ensuring coaxiality after assembly and reducing the problem of axial runout. In use, the grinding wheel dresser and the guide wheel dresser are used to dress the electroplated grinding wheel 19 and the guide wheel 14, respectively. During dressing, the screw 63 is rotated, which drives the screw barrel 64 and the guide post 62 to move axially along the sleeve 61. The guide post 62 drives the dressing cutter 54 to move synchronously, adjusting the distance between the dressing cutter 54 and the surface of the electroplated grinding wheel 19. Then, the hydraulic cylinder 52 drives the support 53 to move. The movement of the support 53 drives the guide post 62 and the dressing cutter 54 to move laterally synchronously, thereby achieving the dressing of the electroplated grinding wheel 19. By setting the aforementioned fixing mechanism, this application can significantly reduce the axial runout generated during the rotation of the electroplating grinding wheel 19.
