Description
技术领域Technical Field
本发明属于开口型陶瓷套管的生产设备领域，尤其涉及一种便于开口型陶瓷套管上膏的装置及其工装。The invention belongs to the field of production equipment for open-type ceramic sleeves, and in particular relates to a device and tooling thereof for facilitating paste application on open-type ceramic sleeves.
背景技术Background Art
开口型陶瓷套管(简称陶瓷套管)主要应用于光无源器件光纤适配器，陶瓷套管的截面为C形，陶瓷套管的内孔要求尺寸较为精准、光滑、高圆度，且同时要求陶瓷套管的内孔与外圆有较高的同轴度，以保证其壁厚较为均匀。传统工艺是对陶瓷套管的内孔进行研磨，即由工人手持陶瓷套管，将其套入到一根转动的扩孔杆中，通过扩孔杆研磨陶瓷套管的内孔，研磨效率低下，同时对陶瓷套管内孔的圆度、内孔与外表面的同心度均无法保证，精度低。Open-type ceramic sleeves (referred to as ceramic sleeves) are mainly used in optical fiber adapters for optical passive devices. The cross-section of the ceramic sleeve is C-shaped. The inner hole of the ceramic sleeve is required to be relatively precise, smooth, and highly round. At the same time, the inner hole of the ceramic sleeve is required to have a high degree of coaxiality with the outer circle to ensure that its wall thickness is relatively uniform. The traditional process is to grind the inner hole of the ceramic sleeve, that is, the worker holds the ceramic sleeve and inserts it into a rotating reaming rod, and grinds the inner hole of the ceramic sleeve through the reaming rod. The grinding efficiency is low, and the roundness of the inner hole of the ceramic sleeve and the concentricity of the inner hole and the outer surface cannot be guaranteed, and the precision is low.
为克服传统工艺中存在的缺陷，应运而生出一种扩孔机，对陶瓷套管的内孔进行扩孔和打磨，扩孔机的申请号为201020273983.3。扩孔机的结构,包括多组扩孔组件，扩孔组件包括扩孔杆，扩孔杆安装于驱动夹头上，驱动夹头安装于驱动装置上；驱动装置上还安装有导轨，导轨与扩孔杆平行，导轨上设置有限位环，扩孔杆的前半部为设置有锥度的圆台部，后半部为圆柱形的圆柱部；扩孔杆前端还设置有载物台，载物台安装于导轨上，载物台可在导轨上沿扩孔杆长度方向移动，载物台的上表面设置有载物槽，载物槽的横截面为半圆形，且与扩孔杆的横截面同心，载物槽的上方设置有压板，压板下表面设置有由尼龙制成的顶块；载物台的后部设置有导向块，导向块上开有导向孔，导向孔的横截面与扩孔杆的横截面同心；导向孔内设置有铜制的耐磨管，导向孔上方还设置定位孔，定位孔内设置有定位螺丝。其中，扩孔杆远离驱动装置的一端为前端，反之为后端。工作时，将载物台向前端平移至脱离扩孔杆，将耐磨管安装入导向孔内，使用定位孔内的定位螺丝固定，将限位环固定于扩孔杆圆柱部的前部；将多个陶瓷套管分别放置于多个载物槽内，将压板压下，在扩孔杆上涂抹研磨膏，打开驱动装置，使扩孔杆开始转动，将载物台沿导轨向后端平移，扩孔杆伸入陶瓷套管内孔开始打磨，当处于载物槽中的陶瓷套管平移至圆柱部时，载物台同时被限位环挡住，此时，陶瓷套管内径被打磨至与扩孔杆圆柱部的外径相等，达到工艺要求，然后向前平移载物台至与扩孔杆脱离，取下陶瓷套管。In order to overcome the defects in the traditional process, a hole expanding machine came into being to expand and grind the inner hole of the ceramic casing. The application number of the hole expanding machine is 201020273983.3. The structure of the reaming machine includes multiple groups of reaming components, the reaming components include reaming rods, the reaming rods are mounted on the driving chucks, and the driving chucks are mounted on the driving device; a guide rail is also mounted on the driving device, the guide rail is parallel to the reaming rod, a limit ring is arranged on the guide rail, the front half of the reaming rod is a truncated cone portion with a taper, and the rear half is a cylindrical cylindrical portion; a loading platform is also arranged at the front end of the reaming rod, the loading platform is mounted on the guide rail, the loading platform can move on the guide rail along the length direction of the reaming rod, a loading groove is arranged on the upper surface of the loading platform, the cross section of the loading groove is semicircular and concentric with the cross section of the reaming rod, a pressing plate is arranged above the loading groove, and a top block made of nylon is arranged on the lower surface of the pressing plate; a guide block is arranged at the rear of the loading platform, a guide hole is opened on the guide block, and the cross section of the guide hole is concentric with the cross section of the reaming rod; a copper wear-resistant tube is arranged in the guide hole, a positioning hole is also arranged above the guide hole, and a positioning screw is arranged in the positioning hole. Among them, the end of the reaming rod away from the driving device is the front end, and the opposite end is the rear end. When working, the stage is translated to the front end to disengage from the reaming rod, the wear-resistant tube is installed into the guide hole, fixed with the positioning screws in the positioning hole, and the limit ring is fixed to the front of the cylindrical part of the reaming rod; multiple ceramic sleeves are placed in multiple loading slots respectively, the pressure plate is pressed down, the grinding paste is applied to the reaming rod, the driving device is turned on, the reaming rod starts to rotate, the stage is translated to the rear end along the guide rail, the reaming rod is inserted into the inner hole of the ceramic sleeve and starts to grind, when the ceramic sleeve in the loading slot is translated to the cylindrical part, the stage is blocked by the limit ring at the same time, at this time, the inner diameter of the ceramic sleeve is polished to be equal to the outer diameter of the cylindrical part of the reaming rod, meeting the process requirements, and then the stage is translated forward to disengage from the reaming rod, and the ceramic sleeve is removed.
申请人使用扩孔机研磨陶瓷套管，发现，由于扩孔杆与陶瓷套管的内孔相配合，研磨膏很难进入到扩孔杆与陶瓷套管之间，导致扩孔杆与陶瓷套管之间存在的研磨膏数量很少，陶瓷套管内壁打磨的光洁度(粗糙度)低，光洁度只能达到Ra0.08，使陶瓷套管的质量等级低，难以卖出高价。而且每个载物槽中只能放置一个陶瓷套管，每根扩孔杆只能对一个陶瓷套管进行研磨，扩孔机上同时进行研磨加工的陶瓷套管数量较少，研磨效率虽然较传统工艺有所提高，但是依然较低。The applicant used a reaming machine to grind ceramic sleeves and found that, due to the matching of the reaming rod and the inner hole of the ceramic sleeve, it was difficult for the grinding paste to enter between the reaming rod and the ceramic sleeve, resulting in a small amount of grinding paste between the reaming rod and the ceramic sleeve, and the polished finish (roughness) of the inner wall of the ceramic sleeve was low, and the finish could only reach Ra0.08, which made the quality grade of the ceramic sleeve low and difficult to sell at a high price. Moreover, only one ceramic sleeve can be placed in each loading tank, and each reaming rod can only grind one ceramic sleeve. The number of ceramic sleeves that can be ground on the reaming machine at the same time is small. Although the grinding efficiency is improved compared with the traditional process, it is still low.
因此，现有的扩孔机用于陶瓷套管的内孔研磨存在陶瓷套管内孔光洁度低和研磨效率较低的缺陷。Therefore, the existing hole expander used for grinding the inner hole of the ceramic casing has the defects of low finish of the inner hole of the ceramic casing and low grinding efficiency.

A screw 25 is provided in each of the long holes 24, and the screw 25 is connected to the block 21 or the shelf 23. The long holes 24 are used to adjust the height of the block 21 or the shelf 23.
工作原理：将模具11放置于搁板23上，模具11的一侧贴靠支架20，模具11的一端贴靠块体21，将多个陶瓷套管一字排列放置在V型槽上，陶瓷套管的开口朝上，此时，陶瓷套管与模具11上的通孔12同轴。将排列好的多个陶瓷套管推入到通孔12中，完成陶瓷套管在模具11上的安装。Working principle: Place the mold 11 on the shelf 23, with one side of the mold 11 against the bracket 20, and one end of the mold 11 against the block 21. Place multiple ceramic sleeves in a line on the V-shaped groove, with the openings of the ceramic sleeves facing upward. At this time, the ceramic sleeves are coaxial with the through holes 12 on the mold 11. Push the arranged multiple ceramic sleeves into the through holes 12 to complete the installation of the ceramic sleeves on the mold 11.
通过正反转装置先使电机8正转，电机8通过螺杆9带动螺母17沿导轨6向外侧移动，螺母17带动载物台7向外侧移动，直至扩孔杆2从凹槽离开。将装好陶瓷套管的模具11放入到凹槽内，通过正反转装置使电机8反转，直至载物台7靠近驱动夹头5。启动驱动装置1，驱动装置1通过驱动夹头5带动扩孔杆2转动，转速2400r/min。然后通过正反转装置先使电机8周期性的正反转，使模具11在圆柱部4上来回移动，移动速度0.25m/s，对陶瓷套管进行研磨。上述参数组合下，陶瓷套管的研磨的光洁度最好，可以达到Ra0.02。The motor 8 is first rotated forward by the forward and reverse device, and the motor 8 drives the nut 17 to move outward along the guide rail 6 through the screw 9, and the nut 17 drives the stage 7 to move outward until the reaming rod 2 leaves the groove. The mold 11 with the ceramic sleeve installed is placed in the groove, and the motor 8 is reversed by the forward and reverse device until the stage 7 is close to the driving chuck 5. Start the driving device 1, and the driving device 1 drives the reaming rod 2 to rotate by driving the chuck 5, with a speed of 2400r/min. Then, the motor 8 is first periodically reversed by the forward and reverse device, so that the mold 11 moves back and forth on the cylindrical part 4, with a moving speed of 0.25m/s, to grind the ceramic sleeve. Under the above parameter combination, the grinding finish of the ceramic sleeve is the best, which can reach Ra0.02.
本发明用于陶瓷套管的内孔研磨具有陶瓷套管内孔光洁度高和研磨效率较高的优点。The invention is used for grinding the inner hole of a ceramic sleeve and has the advantages of high finish of the inner hole of the ceramic sleeve and high grinding efficiency.
