DETAILED DESCRIPTION

[0025] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0026] As shown in Figures 1 to 7 The utility model provides a positioning tool for optical fiber amplifier, including assembly station 1, the top of assembly station 1 is provided with positioning plate 2, the inside of positioning plate 2 is opened with fixed groove 4, the inside of fixed groove 4 places shell 3, the inside of fixed groove 4 swingly installs transmission plate 5, the rear side of positioning plate 2 is opened with transmission bin 7, the rear side of transmission plate 5 is fixedly installed with two groups of ratchet 6, two groups of ratchet 6 are penetrated to the inside of transmission bin 7 and are fixedly installed with pressing plate 9, and the inside wall between pressing plate 9 and transmission bin 7 is elastically connected through spring 8;

[0027] The bottom of transmission bin 7 is opened with first moving groove 17, and the bottom of pressing plate 9 is penetrated first moving groove 17 and is fixedly installed with transmission frame 18, one end of transmission frame 18 is fixedly opened with gear tooth 19, the inside of positioning plate 2 is rotatably installed with gear wheel 21, gear wheel 21 and gear tooth 19 are mutually engaged, and the left and right sides in the inside of fixed groove 4 are opened with second moving groove 22, the inside of second moving groove 22 swingly installs moving block 23, the bottom of moving block 23 is rotatably installed with connecting rod 24, the other end of connecting rod 24 is rotatably connected with gear wheel 21, and the top of left and right groups of moving block 23 is penetrated to the top of fixed groove 4 and is fixedly installed with clamping block 25, and two groups of clamping block 25 are located at the left and right sides of shell 3 and clamp and fix shell 3.

[0028] When the shell 3 and the internal components of the optical fiber amplifier need to be assembled, the worker first prevents the shell 3 in the fixed groove 4, and then pushes the shell 3 backward, so that the shell 3 and the transmission plate 5 abut against each other, the transmission plate 5 pushes the ratchet bar 6 into the transmission bin 7, and the pressing plate 9 moves backward along the first moving groove 17. When the pressing plate 9 moves, the transmission frame 18 moves synchronously along the limiting block 20, so that the gear teeth 19 in the transmission frame 18 drive the gear 21 to rotate. The rotation of the gear 21 drives the moving block 23 to move through the two groups of connecting rods 24. However, the movement path of the moving block 23 is limited by the second moving groove 22, so that the two groups of moving blocks 23 drive the connecting rods 24 to move synchronously to the center of the gear 21, so as to clamp and position the shell 3. It is worth noting that when the ratchet bar 6 moves into the transmission bin 7, the stop block 10 slides on the top of the ratchet bar 6, and the convex block 12 always applies a rotating force to the rotating rod 11 through the elastic potential energy of the movable groove 14. Further, the stop block 10 always abuts against the ratchet bar 6 to ensure the braking of the stop block 10. After the shell 3 is fixed, the worker releases the shell 3. At this time, the cooperation of the ratchet bar 6 and the stop block 10 makes the ratchet bar 6 unable to reset, so as to ensure the firmness of the fixing. When the worker needs to disassemble the shell 3, the worker rotates the knob 15 to lift the stop block 10.

[0029] When the shell 3 is pushed, the transmission plate 5, the ratchet bar 6 and the pressing plate 9 move synchronously. When the pressing plate 9 moves, the gear teeth 19 in the transmission frame 18 drive the gear 21 to rotate. The rotation of the gear 21 drives the moving block 23 to move through the two groups of connecting rods 24, so that the clamping block 25 clamps the shell 3.

The disassembly efficiency of the shell 3 is improved, the positioning accuracy is ensured, and the work burden of the worker is reduced.

The output shaft of the locking motor 28 is fixedly connected with the rotating shaft of the supporting plate 27.

[0031] After the fixing is completed, the worker needs to lower his head to perform the assembly work, and long work will damage the neck, at this time the worker starts the locking motor 28, the output shaft of the locking motor 28 drives the rotating shaft of the supporting plate 27 to rotate, further lifting the supporting plate 27 from the inside of the storage slot 26, and lifting the positioning plate 2 to a suitable angle, then the worker stops the locking motor 28, and the supporting plate 27 is fixed, it is worth noting that the locking motor 28 contains a locking mechanism inside, which can automatically lock the output shaft after stopping working.

[0032] The supporting plate 27 is lifted from the inside of the storage slot 26 by the operation of the locking motor 28, and the positioning plate 2 is further lifted to a suitable angle. Compared with the traditional device, the device can lift the positioning plate 2 to an angle suitable for the worker to assemble when the worker is assembling, which improves the comfort of the worker to a certain extent, thereby reducing the labor burden of the worker and avoiding neck injury.

[0033] Among them, the transmission bin 7 is rotatably installed with a rotating rod 11, the outer wall of the rotating rod 11 is fixedly sleeved with a brake block 10, the brake block 10 and the ratchet 6 abut each other, and one end of the rotating rod 11 penetrates to the outer wall of the positioning plate 2 and is fixedly installed with a knob 15.

[0034] The worker can control the rotation of the rotating rod 11 and the brake block 10 through the knob 15, thereby realizing the disassembly function.

[0035] Among them, the inner wall of the transmission bin 7 is fixedly installed with a fixed sleeve 13, the fixed sleeve 13 and the rotating rod 11 are mutually sleeved, and the inside of the rotating rod 11 is provided with an arc-shaped spring 16.

[0036] Through the provision of the arc-shaped spring 16, the protrusion 12 can rotate in the arc-shaped spring 16, thereby limiting the rotation range of the brake block 10.

[0037] Among them, the outer wall of the rotating rod 11 is fixedly installed with a protrusion 12, and the protrusion 12 and the arc-shaped spring 16 are elastically connected through the movable groove 14.
