Background
The diamond grinding wheel is a circular bonded grinding tool with a through hole in the center, which is made of a matrix made of aluminum alloy and the like, by taking diamond grinding materials as raw materials, respectively taking metal powder, resin powder, ceramic and electroplated metal as bonding agents. The diamond grinding wheel is a special-effect tool for grinding high-hardness and brittle materials such as hard alloy, glass, ceramic, precious stone and the like. Among them, the metal bond grinding wheel is widely used due to its remarkable characteristics of high bonding strength, good formability, long service life, and the like. The metal bond diamond grinding wheel mainly has two types of sintering and electroplating according to different manufacturing modes. The sintered metal-bonded grinding wheel is manufactured by a high-temperature sintering method by using bronze and other metals as bonding agents, and has the advantages of high bonding strength, good formability, high temperature resistance, good heat conductivity and wear resistance, long service life and capability of bearing larger load.
When a mandrel of a constant-speed drive shaft is machined, a sleeve groove and a gear groove are respectively ground at two ends, and a required groove is ground on the circumferential surface of the mandrel by using a sheet-shaped diamond grinding wheel.
The abrasive layer of emery wheel has life when using, and the emery wheel is the consumptive material promptly, and in addition, the abrasive layer is still impaired or warp easily, and then leads to the material to be impaired or warp for the emery wheel of aluminium or aluminum alloy itself, and the emery wheel can't continue to use. The existing grinding wheel is integrated, so that the whole grinding wheel needs to be replaced again when the grinding wheel cannot be used continuously due to abrasion consumption of the grinding material layer or damage of the grinding material layer.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model provides a unilateral emery wheel of dismantling, when the abrasive material layer is impaired and lead to emery wheel itself to have the damage, can only change the part that is equipped with the abrasive material layer, save the cost promptly, reduce the influence to production again.
The utility model discloses a following technical scheme realizes:
the unilateral emery wheel of dismantling is equipped with the rigidity ring body including base member and abrasive material layer along the circumferencial direction of base member, and the external diameter of rigidity ring body is greater than the external diameter of base member, and fixed with the base member in order to dismantle the mode, the abrasive material layer is established at least on the rigidity ring body that is located beyond the base member edge.
An annular first step is arranged along the outer circumferential edge of the substrate, the rigid ring body is an annular sheet, the inner diameter of the rigid ring body is slightly larger than the diameter of the vertical ring surface of the first step, the rigid ring body is nested on the first step, and one surface of the rigid ring body is attached to the horizontal ring surface of the first step; the other side of the rigid ring body is provided with a cover ring, the orthographic projection of the cover ring is overlapped with the horizontal ring surface of the first step, and the cover ring and the rigid ring body are fixedly connected with the base body through a plurality of bolts.
The cover ring is provided with a plurality of bolt head grooves, and the bolt head grooves correspond to the bolts one to one.
The sum of the thicknesses of the rigid ring body and the cover ring is equal to the height of the first stepped vertical ring surface.
The parts of the rigid ring bodies, which are positioned on the outer side of the base body, are provided with abrasive layers.
An annular second step is provided along the outer circumference of the rigid ring.
The utility model has the advantages that:
firstly, the rigid ring body provided with the abrasive layer is not easy to deform, so that the probability of deformation of the abrasive layer is reduced, and the durability is improved.
And secondly, the rigid ring body is detachably fixed on the base body through bolts, and after the abrasive layer is seriously abraded, the rigid ring body can be directly detached and replaced. This avoids the need to replace the entire wheel due to damage to the entire wheel.
