[0031] Furthermore, in order to facilitate the entry of the grinding liquid between the grinding paper and the grinding main disc 2, a liquid inlet hole 201 is arrayed on the grinding main disc 2 located at the outer periphery of the pressurizing column 1. The liquid inlet holes 201 are evenly distributed in an annular array on the grinding main disc 2 at the outer periphery of the pressurizing column 1. During the grinding process, the grinding liquid can enter through the liquid inlet hole 201. At the same time, when cleaning the grinding fixture, the cleaning liquid can be quickly removed through the liquid inlet hole 201.

[0035] Further, if Figure 4 - Figure 8 The quick locking mechanism 4 comprises a wrench 401, a telescopic column 402, a fixing seat 403, a locking block 404, a rotating shaft 405 and an outer spring 406. The outer spring 406 is sleeved on the outer periphery of the telescopic column 402. Both the outer spring 406 and the telescopic column 402 are slidably nested in the inner periphery of the locking block 404. The locking block 404 is movably embedded in one end of the fixing seat 403. One end of the wrench 401 is hinged to the other end of the fixing seat 403 through the rotating shaft 405. One end of the telescopic column 402 is hinged to one end of the locking block 404. The other end of the telescopic column 402 abuts against one end of the wrench 401. The outer spring 406 is sleeved on the outer periphery of the telescopic column 402 and one end abuts against the other end of the telescopic column 402.

[0036] Specifically, the outer periphery of one end of the telescopic column 402 close to the wrench 401 has a flange, and one end of the outer spring 406 abuts against the flange. The outer spring 406 provides a resetting elastic force for the telescopic column 402, so that one end of the locking block 404 can loosen the MPO optical fiber connector after the wrench 401 is pulled downward. When the wrench 401 is pulled upward, the wrench 401 rotates to squeeze the spring 406 and the telescopic column 402 to drive the locking block 404 to flip and realize the locking of the MPO optical fiber connector. When the wrench 401 is pulled downward, the outer spring 406 resets to resist the telescopic column 402 and drives the locking block 404 to reset and loosen the MPO optical fiber connector.

[0037] Furthermore, a locking block 404 is embedded in one end of the inner periphery of the MPO socket 202 and is used to lock the MPO optical fiber connector. A fixing seat 403 is arranged on the grinding main disk 2 and one end is adjacent to the MPO socket 202. One end of the wrench 401 is hinged to the other end of the fixing seat 403 away from the MPO socket 202. One end of the telescopic column 402 is hinged to the locking block 404, and the other end of the telescopic column 402 is against one end of the wrench 401.

[0038] Specifically, the locking block 404 has an arc-shaped surface at one end close to the mpo optical fiber connector, and the upper end of the locking block 404 is a barb head extending toward one side of the mpo optical fiber connector, and a slot 4042 is provided on the barb head for resisting the top of the mpo optical fiber connector, and the slot 4042 can be embedded in one side of the top of the mpo optical fiber connector to match the top of the mpo optical fiber connector. The fixing seat 403 is a triangular cavity structure, and a through hole is provided in the fixing seat 403 to penetrate the front and rear ends thereof for accommodating the telescopic column 402, and a front notch is provided at one end of the fixing seat 403 for embedding the locking block 404, and a rear notch is provided at the other end of the fixing seat 403, and one end of the wrench 401 is embedded in the rear notch, and the upper end of the rear notch is hinged to the L-shaped wrench 401 through the rotating shaft 405, and the lower part of one end of the wrench 401 resisting the telescopic column 402 has a convex plate supporting one end of the telescopic column 402, and the other end of the telescopic column 402 is hinged to the other end of the locking block 404. One end of the wrench 401 that resists the telescopic column 402 is an arc surface, and the upper end of the wrench 401 has a plane. When the wrench 401 is pulled downward, the arc surface flips so that the telescopic column 402 drives the barb head of the locking block 404 to deflect toward the wrench 401 side, and the slot 4042 is away from the MPO socket 202. The MPO optical fiber connector to be ground is inserted into the MPO socket 202, and then the wrench 401 is pulled upward, and the plane flips to resist one end of the telescopic column 402. The other end of the telescopic column 402 squeezes the locking block 404 to deflect the barb head in the opposite direction, and the slot 4042 on the barb head is buckled on one side of the upper end of the MPO optical fiber connector. The plane on the upper side of the wrench 401 rotates and resists one end of the telescopic column 402 to achieve the clamping and locking of the MPO optical fiber connector.

[0039] Furthermore, the telescopic column 402 includes a telescopic rod, a blind cylinder and an inner spring. One end of the telescopic rod is hinged to one end of the locking block 404, one end of the blind cylinder is abutted against one end of the wrench 401, an inner spring is sleeved in the blind cylinder, and the other end of the telescopic rod is embedded in the blind cylinder and abutted against one end of the inner spring.

[0040] Specifically, an annular flange is arranged on the periphery of the closed end of the blind barrel, and the lower end of the flange is supported on the convex plate of the wrench 401. The inner spring is nested in the blind barrel and located on one side of the closed end, and the inner spring resists the end of the telescopic rod extending into the blind barrel. The inner spring provides buffer pressure when the telescopic rod squeezes the locking block 404, so as to prevent the locking block 404 from crushing the mpo optical fiber connector.

[0041] Furthermore, in order to facilitate the hinge connection between the locking block 404 and the telescopic rod, an arc-shaped notch 4041 is provided at one end of the locking block 404. The arc-shaped notch 4041 is provided at the end of the locking block 404 near one end of the telescopic rod, and the arc-shaped notch 4041 passes through the front and rear sides of the locking block 404. The cross section of the arc-shaped notch 4041 is a C-shaped opening larger than a semicircle, and a sphere is provided at one end of the telescopic rod, and the sphere is embedded in the arc-shaped notch 4041 and cooperates with the arc-shaped notch 4041 to achieve hinge connection.

[0042] The grinding fixture provided by the utility model is used in conjunction with an automatic grinding machine, and the clamping manipulator provided on the automatic grinding machine is used to grab the pressurized column 1 to move the grinding fixture. Before grinding, the MPO optical fiber connector is manually clamped in the MPO jack 202 of the grinding fixture, and the MPO optical fiber connector is locked after clamping before grinding and removed after grinding through the quick locking mechanism 4.
