Description

Grind locating ring

Technical field

The utility model is about a kind of grinding locating ring, more detailed it, be meant a kind of grinding locating ring that is applied to circle location grinding operation especially.

Background technology

At present, general industry is applied to grind the structure of the grinding locating ring of crystal operation, normally constitute by the grinding ring body of the base portion ring body of metal and the macromolecular material institute that mutually combines, grind locating ring when using, the length in its life-span, abrasion speed except the grinding ring body that depends on this macromolecular material, the base portion ring body of metal and the fastness of grinding integrated structure between the ring body, it also is a key factor, because grind locating ring in the attrition process process, produce the violent rubbing action of continuation between meeting and crystal and the processing parts, the reversal of stress that it produced, then can produce destructive effects to base portion ring body that grinds locating ring and the integrated structure that grinds ring body, in case during the phenomenon that generation is loosening or disengagement is peeled off between base portion ring body and the grinding ring body, mean that also this grinding locating ring scraps, and need change in addition.

The base portion ring body of known grinding locating ring and the fixed form that combines of grinding ring body, roughly adopt as " mode of following of cyrstal sphere grinding ring " of No. the 470690th, tw Taiwan patent announcement as described in content, this patent is mainly carried out flame treatment earlier disclosing the commissure will grind locating ring, handle base portion ring body and the commissure wiping of grinding ring body clean again, and then it is fixing to utilize epoxy resin that the two is adhered, and makes the base portion ring body reach the fixing state that combines with the grinding ring body.

But, because the commissure of aforesaid base portion ring body and grinding ring body, on the whole be planar structure, therefore this combination by adhesion also can't effectively overcome the reversal of stress that is produced when crystal grinds, the vibrations or the high-temperature digestion that are produced during easily because of the grinding crystal, make epoxy resin lose bonding effectiveness, thereby the base portion ring body that causes grinding locating ring produces the phenomenon that comes off or peel off with the grinding ring body, by this bonding mode, this base portion ring body and the bond strength of grinding between the ring body still have weak point like this.

The utility model content

In view of this, main purpose of the present utility model is to provide a kind of grinding locating ring, can the efficient hardening base portion with grind section between combine, prevent to grind locating ring and produce easily and peel off or come off, and then prolong the service life of this grinding locating ring.

In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of grinding locating ring, and it includes:

Base portion, described pedestal is structure ringwise, and first side of described base portion is a locking face, and described locking face is provided with locating hole; Second side of described base portion is a faying face, and described faying face is provided with conjugate foramen, and described conjugate foramen connects to be established locking conjugative component arranged;

Grind section, described grind section is structure ringwise, and first side of described grind section is a faying face, and described faying face is provided with entrance hole; Second side of described grind section is an abradant surface;

On the described faying face of described base portion and described grind section, be coated with adhesion glue respectively, the described conjugative component of described conjugate foramen that is locked on described base portion can clip when described base portion combines with described grind section in the described entrance hole of described grind section, form the double fixed structure.
