DETAILED DESCRIPTION

[0023] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0024] Embodiment 1, in combination with the attached Figure 1 , 3 -4, an optical fiber connector end polishing device, comprising a frame 1, a rotatable workbench 2 is provided at one end of the top surface of the frame 1, and a plurality of concentrically arranged annular abrasive belts 3 are sequentially provided on the upper surface of the workbench 2 from the inside to the outside, and the particle size of the annular abrasive belts 3 gradually decreases from the inside to the outside;

[0025] It should be noted that the annular abrasive belt 3 can be bonded to the upper surface of the workbench 2 by bonding, for example, by Velcro; as required, the annular abrasive belt 3 is concentrically arranged with the upper surface of the workbench 2 .

[0026] As required, an eccentric connecting portion 21 is provided on the lower surface of the workbench 2 , and a driving motor 7 having an output shaft drivingly connected to the connecting portion 21 is provided on the frame 1 at a position corresponding to the lower portion of the workbench 2 .

[0027] According to needs, a ball bearing is provided at a position on the top surface of the frame 1 corresponding to the lower surface of the workbench 2, and the workbench 2 is supported by the ball bearing to increase the stability of the workbench 2 and ensure stable eccentric rotation of the workbench 2.

[0028] A rotatable rotating shaft 4 is disposed at the other end of the workbench 2 . As required, a feed motor 10 for driving the rotating shaft 4 to rotate is disposed at a position below the rotating shaft 4 of the frame 1 .

[0029] The shaft body of the rotating shaft 4 is provided with a vertical slide rail pair 5, the sliding portion of the vertical slide rail pair 5 is located above the workbench 2, and is provided with a clamping assembly 6 for clamping and fixing the optical fiber connector;

[0030] As needed, combine with Figure 5 The clamping assembly 6 includes a tooling main board 61 fixedly connected to the sliding part of the vertical slide rail pair 5, and a loading hole is provided in the middle of the tooling main board 61; a locking ring fixed section 62 is provided on one side of the bottom surface of the tooling main board 61, and a locking ring movable section 63 is provided on the other side of the bottom surface of the tooling main board 61, and the locking ring movable section 63 is connected to the tooling main board 61 through an adjusting screw, so that the locking ring movable section 63 can move toward the locking ring fixed section 62 to achieve clamping and fixing of the optical fiber connector.

[0031] Such an arrangement can drive the workbench 2 to rotate eccentrically through the driving motor 7, thereby driving all the annular sanding belts 3 to rotate eccentrically; at the same time, the optical fiber connector clamping assembly 6 and the sliding part of the vertical slide rail pair 5 move downward under the action of gravity, so that the end of the optical fiber connector to be polished contacts the annular sanding belt 3, and the rotating shaft 4 is driven to rotate by the feed motor 10, and the rotating shaft 4 drives the vertical slide rail pair 5 to swing, thereby driving the optical fiber connector to swing, so that the trajectory of the end of the optical fiber connector to be polished on the annular sanding belt 3 is an "8" shape, so that the polishing direction of the end of the optical fiber connector to be polished always changes, thereby improving the polishing quality.

[0032] Since the upper surface of the workbench 2 is sequentially provided with a plurality of concentrically arranged annular sanding belts 3 from the inside to the outside, in conjunction with the rotation of the rotating shaft 4, the end face of the optical fiber connector can be processed continuously through multiple processes, thereby improving the work efficiency;

[0033] Since the contact force between the optical fiber connector and the annular abrasive belt 3 is exerted by the clamping assembly 6 and the gravity of the sliding part of the vertical slide rail pair 5, the grinding pressure of the optical fiber connector is a constant pressure, which can effectively improve the grinding quality and solve the technical problem in the prior art that the friction force between the optical fiber connector and the grinding disk needs to be controlled by a grinder, which requires a very high-precision grinder.

[0034] Embodiment 2, combined with the attached Figure 3, a fiber optic connector end polishing device, based on the first embodiment, the rotating shaft 4 and the fixed part of the vertical slide rail pair 5 are correspondingly hinged through two connecting rods 8 spaced apart from each other, so that the rotating shaft 4, the fixed part of the vertical slide rail pair 5 and the two connecting rods 8 form a parallelogram structure; in this way, under the action of the gravity of the clamping assembly 6 and the vertical slide rail pair 5, the end of the fiber optic connector to be polished contacts the annular sanding belt 3, ensuring that the polishing pressure of the fiber optic connector is constant. At the same time, when the fiber optic connector is disassembled, the clamping assembly 6 and the vertical slide rail pair 5 can be lifted upward to separate the fiber optic connector from the annular sanding belt 3, preventing the friction movement between the polished end of the fiber optic connector and the annular sanding belt 3 from being in an uncontrollable pressure during the disassembly process, which affects the quality of the polished end of the fiber optic connector.

[0035] Embodiment 3, in combination with the attached Figure 1-2 , a fiber optic connector end grinding device, which is different from the second embodiment in that the upper end of the rotating shaft 4 is threadedly matched with a handle 41 coaxial therewith, and the handle 41 is rotatably connected to the T-bar 42; the fixed part of the vertical slide rail pair 5 is hinged with a lever 51, and the lever 51 is provided with a U-shaped hole for inserting the wing of the T-bar 42 at one end corresponding to the T-bar 42, and the other end of the lever 51 is provided with a waist-shaped hole along its axial direction, and the sliding part or the clamping assembly 6 of the vertical slide rail pair 5 is provided with a pin shaft 9 that matches and is inserted into the waist-shaped hole.

[0036] According to the needs, the upper end surface of the rotating shaft 4 is provided with a threaded hole coaxial therewith, and the lower end of the handle 41 is provided with a threaded portion matching the threaded hole;

[0037] Specifically, the cross section of the wing of the T-shaped rod 42 is circular, which can ensure that the wing of the T-shaped rod 42 can move and rotate relative to the U-shaped hole.

[0038] It should be noted that in this embodiment, the fixed portion of the vertical slide rail pair 5 is fixedly connected to the rotating shaft 4 .

[0039] This arrangement allows the handle 41 to be turned downward when the optical fiber connector is disassembled, so that the handle 41 drives the T-bar 42 to move downward, and the T-bar 42 drives the lever 51 to rotate, and the sliding portion of the vertical slide rail pair 5 or the clamping assembly 6 moves upward under the action of the lever 51, so that the optical fiber connector is separated from the annular abrasive belt 3, thereby preventing the grinding end of the optical fiber connector and the annular abrasive belt 3 from being in a state of uncontrollable frictional movement under pressure during the disassembly process, thereby affecting the quality of the grinding end of the optical fiber connector.

[0040] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
