Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connector shell processing, in particular to an auxiliary positioning device for optical fiber connector shell processing. Background Art

[0002] Fiber optic connectors are devices that are detachable (movable) connections between optical fibers. They precisely connect the two end faces of the optical fiber so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent possible, and the impact on the system caused by its involvement in the optical link is minimized. This is the basic requirement of fiber optic connectors. Fiber optic connectors need to be positioned and locked during processing to ensure their stability and facilitate subsequent operations.

[0003] The publication number is CN218396271U, and the name is a positioning structure for cutting processing of a coaxial connector shell. It mentions that "the clamping rod 4 pushes the movable clamping block 7 to squeeze and clamp the side wall of the shell until it is tightened, and then the clamping rod 4 on the other symmetrical side of the stabilizing body 2 is tightened, and the clamping plate 13 and the second return spring 15 cooperate with each other to achieve the locking or loosening of the clamping rod 4". It can be seen from the attached figure of the specification that there are four clamping rods 4, which correspond to the four outer sides of the stabilizing body 2 respectively. When locking the shell, the four clamping rods 4 need to be pushed to press the movable clamping block 7 against the shell, which is more troublesome to operate. Secondly, in the loosening process, the corresponding clamping plates 13 need to be pulled in turn to loosen the corresponding clamping rods 4, resulting in low efficiency in loosening the shell, which in turn affects subsequent processing and has poor practicality.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 The utility model provides an auxiliary positioning device for processing an optical fiber connector shell, including a lower seat 2 and an upper seat 1 connected to the top of the lower seat 2. A clamping mechanism for clamping the shell is connected inside the upper seat 1. The clamping mechanism includes a plurality of pressure blocks 7, a plurality of push-pull plates 9, a screw sleeve 10, and a rotating rod 11. Three pressure blocks 7 and push-pull plates 9 can be provided, and the adjacent angles are 120°. The shell can be placed between the three pressure blocks 7. The synchronous movement of the three pressure blocks 7 can not only achieve the positioning purpose, but also make the shell be in the center position of the upper seat 1, which is convenient for subsequent processing. The pressure block 7 is movably connected to the upper seat 1, and the two ends of the push-pull plate 9 are connected to the pressure block 7 and the screw sleeve 10. The rotating rod 11 is used to drive the screw sleeve 10 to rise and fall. The screw sleeve 10 is threadedly connected to the rotating rod 11, and the rotating rod 11 is connected to a driving mechanism for driving the rotating rod 11 to rotate.

[0022] When positioning the shell, place the shell in the upper seat 1, pull the rotating handle 5 to separate it from the limit seat 3, at this time the spring 17 is compressed, and then rotate the rotating handle 5 to drive the driving rod 15 to rotate, the conical tooth 12 matches the conical tooth 2 14, which can drive the rotating rod 11 to rotate, and the screw sleeve 10 applies an upward thrust or a downward pull to multiple push-pull plates 9 simultaneously, which can drive multiple pressure blocks 7 to move synchronously away from or close to the center direction of the upper seat 1, thereby realizing the positioning and locking of the shell, improving the stability of the shell, and facilitating subsequent processing.

[0023] The clamping mechanism also includes a plurality of sliding blocks 8, which are used to guide the corresponding pressing blocks 7. The two ends of the push-pull plate 9 are connected to the sliding blocks 8 and the screw sleeve 10. The sliding block 8 plays a good guiding role for the pressing block 7, so that the pressing block 7 moves steadily. Secondly, a rubber pad is arranged on the inner side of the pressing block 7 to prevent the pressing block 7 from directly contacting the shell and damaging the shell surface due to excessive pressure. When the screw sleeve 10 moves up, an upward thrust is applied to the three push-pull plates 9, so that the three pressing blocks 7 move synchronously away from the center direction of the upper seat 1, which is convenient for loosening the shell; when the screw sleeve 10 moves down, a downward pulling force is applied to the three push-pull plates 9, so that the three pressing blocks 7 move synchronously toward the center direction of the upper seat 1, which is convenient for positioning and fixing the shell.

[0024] A plurality of sliding holes 6 are arranged in the upper seat 1 , and the sliding blocks 8 are slidably connected to the corresponding sliding holes 6 , and the sliding holes 6 are rectangular holes.

[0025] The top of the rotating rod 11 is rotatably connected to the upper seat 1, and the bottom of the rotating rod 11 is connected to a connecting rod 13, and the end of the connecting rod 13 is rotatably connected to the lower seat 2, which can improve the rotation stability of the rotating rod 11 and make the screw sleeve 10 rise and fall stably.

[0026] The driving mechanism includes conical tooth 2 14, a driving rod 15, a limit seat 3, a limit groove 4, a rotating handle 5, a guide groove 16, a spring 17, and a guide block 18. The two ends of the driving rod 15 are connected to the conical tooth 2 14 and the guide block 18. The limit seat 3 is connected to the outer side of the lower seat 2. The limit groove 4 is arranged in the limit seat 3, and the limit groove 4 matches the rotating handle 5. The guide groove 16 is arranged in the rotating handle 5. The guide block 18 is slidably connected to the guide groove 16. The spring 17 is located in the guide groove 16, and the two ends of the spring 17 are connected to the rotating handle 5 and the guide block 18. The conical tooth 2 14 is used to drive the rotating rod 11 to rotate. When the rotating handle 5 is rotated, a pulling force is applied to the rotating handle 5 to separate the rotating handle 5 from the limiting seat 3, and the guide block 18 slides in the guide groove 16, and the spring 17 is gradually compressed. The rotation of the rotating handle 5 can synchronously drive the rotation of the guide block 18 to realize the rotation of the driving rod 15, and the driving rod 15 drives the cone-shaped tooth 2 14 to rotate. The cone-shaped tooth 2 14 cooperates with the cone-shaped tooth 1 12 to drive the rotating rod 11 to rotate, which is convenient for locking or loosening the shell. When the shell is in the locked state, the rotating handle 5 is directly released, and the compressed spring 17 drives the rotating handle 5 to return to its original position, so that the end of the rotating handle 5 is connected to the limiting groove 4, thereby realizing the rapid locking of the rotating handle 5, and preventing the rotating handle 5 from loosening due to vibration during processing of the shell, which affects the stability of the shell.

[0027] The rotating rod 11 is connected with the conical tooth 12, and the conical tooth 2 14 is meshed and connected with the conical tooth 12, so the transmission efficiency is high.

[0028] The cross-sections of the rotating handle 5 and the guide block 18 are regular polygonal structures.

[0029] Working principle: Place the shell in the upper seat 1, apply tension to the rotating handle 5, separate the rotating handle 5 from the limiting seat 3, and the spring 17 is in a compressed state. Then rotate the rotating handle 5 to drive the guide block 18 to rotate, and the guide block 18 drives the driving rod 15 and the conical tooth 2 14 to rotate. The conical tooth 2 14 cooperates with the conical tooth 1 12 to drive the rotating rod 11 to rotate, so that the screw sleeve 10 moves downward, and the screw sleeve 10 simultaneously applies a downward pulling force to the three push-pull plates 9, so that the three pressure blocks 7 move synchronously toward the center direction of the upper seat 1, until the three pressure blocks 7 are pressed against the outside of the shell, stop the rotating handle 5 from rotating, and realize the positioning and locking of the shell, which is convenient for subsequent processing. Furthermore, the rotating handle 5 can be directly loosened, and the compressed spring 17 drives the rotating handle 5 to return to its position, so that the rotating handle 5 is connected to the limiting groove 4, and then the rotating handle 5 is locked and limited to prevent the rotating handle 5 from loosening due to vibration during processing, which affects the stability of the shell. When the shell is processed, pull the rotating handle 5 to separate it from the limit seat 3, and then turn the rotating handle 5 to drive the rotating rod 11 to rotate, so that the screw sleeve 10 moves up, and the three push-pull plates 9 are simultaneously applied with an upward thrust, which can drive the three pressing blocks 7 to move synchronously away from the center direction of the upper seat 1, that is, the pressing blocks 7 are separated from the shell, so that the shell is loosened and it is easy to take it out from the upper seat 1.
