The grinding miller is better than domestic and overseas grinding millers with same equipment in manufacture quality at present. In correct use, a steel wire cannot rupture in the grinding process, the production efficiency is high, and the labor cost is saved.

Description

Technical field [0001] The invention relates to a ceramic ferrule grinding device, in particular to a ceramic ferrule inner hole grinding machine, belonging to the technical field of optical fiber equipment. Background technique [0002] Optical fiber ceramic ferrule is a high-precision cylindrical special ceramic component that is precisely aligned in the optical fiber connector plug. It is used to fix the optical fiber. Because the packaged component product has extremely high requirements on size, form and position tolerance and reliability In the stainless steel (or other materials) precision parts used in its packaging, the tolerance of the aperture size is usually 0.5~1um, and the shape tolerance such as coaxiality is usually less than 1um. In order to meet the strict requirements of its products, the various parts of the finished product The processing accuracy requirements are also extremely high. In order to meet this requirement, the shape and size of the ceramic ferru...

Problems solved by technology

For a long time, the processing and production of this type of ceramic ferrule has been basically produced by Japanese companies or processed by Japanese high-end equipment such as CITIZEN, STAR, SUMGAMI, KEYENCE and other companies. Its price is very high, thereby affecting the production cost of the metal component of the optical fiber ceramic ferrule, and the processing of the inner hole of the ceramic ferrule using the above-mentioned equipment in the prior art mainly relies on manual grinding; the specific method is to make the grinding steel wire into It is well known in the industry that it includes a tapered shape at one end. Apply abrasive paste on the grinding steel wire, and then manually put the ceramic ferrules to be ground on the grinding steel wire coated with abrasive paste one by one. Up to 20 pieces can be set at a time. Then use the grinding fixture to clamp the ceramic ferrule. During the high-speed rotation of the ceramic ferrule in the fixture, the grinding steel wire is continuously moved left and right by hand. The grinding steel wire moves back and forth in the inner hole of the ceramic ferrule to grind the steel wire. The tapered part carries the abrasive and the inner hole of the ceramic ferrule relative to the reciprocating and rotating friction to realize the grinding of the inner hole. During the grinding process, it is necessary to manually add the abrasive to the grinding steel wire. After the manual judgment is completed, when the grinding is completed, Remove the ceramic ferrule by hand

Due to the small volume of the ceramic ferrule, the processing equipment and process operations of the prior art require manual operation, and the error of manual operation is relatively large, resulting in poor grinding quality, and the aperture and true roundness indicators are often out of tolerance. Especially in the case of a set of multiple ceramic ferrules at one time, the yield rate is low; at the same time, the efficiency of manual grinding is also very low, but the labor intensity is high, and the production cost is also significantly increased under the condition of increasing labor costs. , Grinding steel wire during high-speed rotation will also pose a greater safety hazard to the operator

In order to overcome this situation, the industry has developed different forms of ceramic ferrule inner hole grinding machines. For example, China Application No.: 201420027042. The automation of the inner hole grinding of the ferrule improves the production efficiency, but there are defects such as complex structure, cumbersome operation, and easy breakage of the grinding steel wire, which needs further improvement and improvement
