Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of polishing and grinding consumables, and more particularly to a diamond polishing wheel with elasticity. BACKGROUND

[0002] The fillet transition surface and the rim plate area of the blade leaf basin are difficult points in the manual polishing process of the blade, and are also difficult points in the automatic polishing process. The existing blade rim plate and fillet transition surface are mainly shaped, ground and polished by manual polishing, mainly using superimposed wheels and hard grinding heads. The blade leaf basin is generally first polished with a hard grinding head to remove surface sand points and other casting defects.

[0003] The existing electroplated grinding and polishing wheel or brazed grinding and polishing wheel has a rigid structure design. When the blade root fillet is ground and polished, the outer surface of the grinding and polishing wheel cannot change flexibly with the blade root fillet. The hard grinding head has strong removal capacity, but the polished surface is uneven, and secondary processing is required after polishing. Some grinding heads also have trimming problems. When a batch of blades have errors, the surface of the workpiece polished by the rigid diamond grinding and polishing wheel cannot meet the design requirements. The superimposed wheel has weak surface sand point removal capacity, and because it is a leaf basin area, the contact area between the grinding head and the workpiece is large during polishing, and the heat generated during polishing is not easy to dissipate, which can easily burn the workpiece and the polishing wheel. Therefore, the polishing surface quality and polishing efficiency are affected during use. The flexible abrasive belt wheel can meet the self-adaptive requirements of blade root fillet grinding and polishing, but the service life of the abrasive belt is low and needs to be replaced frequently, thereby affecting the work efficiency of automatic grinding and polishing. During abrasive belt wheel grinding and polishing, overcutting is easily caused at the blade leading and trailing edge cut-in or cut-out positions due to the deformation of the abrasive belt, thereby affecting the grinding and polishing quality.

[0004] Therefore, a diamond polishing wheel with elasticity is provided to solve the above problems. SUMMARY
