Description

Split type grinding wheel of polishing

Technical Field

The utility model relates to the technical field of polishing grinding wheels, in particular to a split polishing grinding wheel.

Background

The grinding wheel is a bonded grinding tool with certain strength and is formed by bonding common grinding materials into a certain shape (most of the grinding materials are round and the center of the grinding materials is provided with a through hole). It is generally composed of abrasive, binder and air holes, which are commonly referred to as the three elements of bonded abrasive tools. According to different classifications of bonding agents, there are ceramic (bonding agent) grinding wheels, resin (bonding agent) grinding wheels and rubber (bonding agent) grinding wheels. The grinding wheel is one of the grinding tools with the largest dosage and the widest use surface, and can rotate at high speed during use, and can perform rough grinding, semi-finish grinding, slotting, cutting and the like on the outer circle, the inner circle, the plane, various molded surfaces and the like of metal or nonmetal workpieces.

The split grinding wheel disclosed in the Chinese patent application publication CN207171837U comprises a base body and a grinding insert, wherein the base body is disc-shaped; the grinding insert is connected to the disk surface of the base body along the circumferential direction and can be detached and fixed with the base body; the grinding insert is supported by the base body, the arc-shaped surface of the grinding insert protrudes out of the base body, the protruding surfaces of the plurality of circumferentially arranged grinding inserts are positioned on the same cylindrical surface, and the grinding is performed through the arc-shaped edge during rotation. The split type grinding wheel adopts a detachable split type structural design, the grinding insert can be replaced, when the grinding insert is damaged, the grinding insert is replaced, the replacement process is simple and convenient, and the processing and material cost can be reduced.

However, the device also lacks protection device, when the grinding wheel is in work, under the condition of lacking protection device, the threaded rod on the fixing ring is easy to loosen, even slide or fall off when rotating, so that the grinding insert flies out, and the injury of staff can be caused. Moreover, several grinding inserts in the device can not be tightly connected on the outer surface, and when the objects are polished, the objects to be polished can not be uniformly polished, and even the substrate can be worn.
