Description
Technical field
The present invention relates to the processing equipment fields of fiber optic telecommunications equipment, more particularly to one kind is for minimizing, multichannel connects
Connect the porcelain bushing inner circle grinding device and grinding method of device.
Background technique
Fiber optic communication has undergone the development in more than 40 years away from the present, with the rapid development of global IT application and internet,
More highlight the importance, urgency and certainty of network fiber.Optical fiber development at present has marched toward the phase III, into net
The miniaturization of network, the development of multichannel connector, as optical fiber connector essential core component, porcelain bushing have positioning,
Centering, fastening, guarantee interchangeability, in drawing repeatedly, a variety of critical functions, the porcelain bushing internal diameter such as retention property stabilization are light
The benchmark of fine centering positioning, dimensional accuracy and surface smoothness requirements are very high, therefore casing tube internal hole grinding is wherein most to close
Key is also most difficult process.Zirconia ceramic sleeve is made of typical high rigidity brittle materials, and its machining accuracy
It is required that very high, wherein inner hole grinds difficult point: first is that aperture is small, draw ratio is big, and traditional milling tool can not contact finished surface, real
Existing dimensional accuracy is extremely difficult；Second is that workpiece material hardness and strength are high, there is high wearability, and must be protected in technique
Demonstrate,prove enough grinding efficiencies；Third is that required precision is high, and detection difficult, it is necessary to guarantee by grinding device.
And be used to minimize, the porcelain bushing of multichannel connector it is smaller compared with conventional FC, SC connector ferrule,
Draw ratio is bigger, at present only manual operations or single grinding operation, and manually operated error is again larger, and yields is low, work
It is inefficient, and single grinding operation support staff is more, casing is by being manually loaded into one by one, and processing is also one by one
Take off, from cleaning, charging, upper cover plate, unload cover board, feeding, a machine will at least be equipped with 2 people's back works, single per capita
Efficiency or lower in the time of position.It gradually adopted vertical lapping machine to be transformed by bench drill later, and carried out bull simultaneous processing, such as
The Chinese invention patent file " Multi-station semi-automatic inner pore digital controlled grinding device " of Publication No. CN200620103891, because by work
The most 10 drill rod simultaneous grindings of limitation for making platform need artificial loading and unloading to be operated although grinding efficiency increases, auxiliary
The personnel that help or more, cost of investment is relatively high.And the Chinese invention patent file " light of 102814728 A of Publication No. CN
The hole abrading machine of fine ceramic insertion core metal assembly porcelain bushing ", using circulation feed unit and pusher unit gradually pusher
Processing, the quality of product is difficult to control, cannot process from both ends because workbench can not be overturn, and abrasive can only from one into
Enter, the precision unevenness dimensional discrepancy processed is larger, therefore qualification rate can only be controlled 60%.
On the other hand, existing porcelain bushing milling apparatus, mostly uses greatly vertical grinding, vertical lapping machine top heavy,
It is difficult to control precision, and because of the unicity of grinding clamp, the variation of all kinds of nonstandard casings can not be coped with, it cannot be according to difference
Demand adjustment carry out nonstandard processing.Furthermore existing grinding technics can not carry out multistage grinding, can not regulate and control the hole of grinding
Diameter size and machining accuracy.
In summary, the prior art still has many deficiencies.
Summary of the invention
Goal of the invention of the invention is to solve the limitation of above-mentioned existing fiber porcelain bushing inner circle grinding device, provides one
, it can be achieved that multi-stage accuracy is ground, qualification rate is high for kind of high degree of automation, easy to operate porcelain bushing inner circle grinding device and grinds
