The manufacturing process of ceramic ferrules includes injection molding, blank separation, blank degreasing and sintering, and end face grinding. However, after the manufacturing is completed and assembled into FBG, it needs to be polished according to the requirements. Traditional equipment uses grinding discs, which are mostly ground individually. This method is inefficient and relies more on manual adjustment operations. In addition, the consistency of the products is poor and the defective rate is high. At the same time, due to the different grinding angles of the ferrules, the grinding discs need to be replaced frequently to meet the grinding requirements.

[0027] like Figures 1 to 6As shown, a FBG ceramic ferrule end face grinding device comprises a workbench 1, a clamping mechanism, a driving mechanism and a grinding mechanism. A supporting platform 2 is arranged in the middle of the workbench 1, and a mounting seat 3 is arranged on the supporting platform 2. A plurality of placement grooves matching the FBG ceramic ferrules 4 are arranged on the mounting seat 3. The FBG ceramic ferrules 4 are placed in the placement grooves one by one. The clamping mechanism is movably arranged on the supporting platform 2. The grinding mechanism is arranged on the workbench 1 and is located on both sides of the supporting platform 2. The driving mechanism is arranged at the bottom of the supporting platform 2, and the driving mechanism is respectively connected to the grinding mechanisms on both sides by transmission, and can drive the grinding mechanisms on both sides to synchronously move toward the supporting platform 2 until they abut against the corresponding end of the FBG ceramic ferrule 4. At the same time, the driving mechanism drives the clamping mechanism to move downward until the FBG ceramic ferrule 4 is clamped in the placement groove, and the grinding mechanism can grind the end face of the FBG ceramic ferrule 4 in the placement groove.

[0028] The FBG ceramic ferrule end face grinding device of the present invention drives the clamping mechanism through a driving mechanism to clamp the FBG ceramic ferrule 4 in the placement grooves arranged side by side in the mounting seat 3, and drives the grinding mechanisms on both sides to synchronously move toward the support table 2 to abut against the corresponding end of the FBG ceramic ferrule 4 through the driving mechanism, and the grinding mechanism grinds the end face of the FBG ceramic ferrule, thereby realizing batch automatic grinding of the FBG ceramic ferrule 4, greatly improving the grinding efficiency, and having strong versatility by replacing the corresponding mounting seat 3 according to the FBG ceramic ferrule 4 of different specifications.

[0030] In practice, in order to facilitate the placement of the FBG ceramic ferrule 4 in the placement groove and facilitate the use of the entire device, the placement grooves are evenly spaced on the mounting seat 3, and the connecting rods 7 on the inner top wall of the lifting frame 5 are also evenly spaced one by one.

[0031] In order to make the slide bar 6 automatically rebound, blind holes are respectively provided at both ends of the mounting seat 3, and a return spring is provided in the blind hole. The lower end of the slide bar 6 extends into the blind hole and is connected to the upper end of the return spring. When the driving mechanism synchronously drives the block 9 to drive the lifting frame 5 to move downward, the lifting frame 5 drives the slide bar 6 to move downward in the blind hole and compresses the return spring.

The four pressing rods 15 are respectively arranged at both ends of the two moving links 13, and an inclined section is arranged at one end of the pressing rod 15 close to the support platform 2.
