Since the inside of the box body is a gear structure, after power-on testing, the position where the pin hole of the shaft stays when stationary is random, and it is difficult to directly move it with external force. Summary of the Utility Model
[0003] The purpose of the utility model is to provide an optical fiber positioning device for a gearbox shaft with a simple structure and automatic operation in view of the above-mentioned deficiencies of the prior art.
[0004] The technical solution of the utility model is realized as follows: an optical fiber positioning device for a gearbox shaft includes a base, a positioning seat is arranged on the base, and an electric control component is arranged on the base; an installation seat is arranged on one side of the positioning seat, and an installation cylinder is horizontally arranged on the installation seat; a positioning shaft matched with the gearbox shaft is arranged in the installation cylinder through an elastic component, and opposed optical fibers are arranged on the upper and lower side walls of the installation cylinder.

[0008] After the utility model adopts the above structure, the gearbox shaft is matched with the positioning shaft to make the pin hole located at the opposed optical fiber and start to rotate slowly. When the pin hole rotates to be perpendicular to the bottom surface of the box body, the opposed optical fiber passes through the pin hole, and the electric control component cuts off the power supply of the gearbox to stop the rotation and keep the pin hole in a vertical state. Description of the Drawings
[0009] The following further elaborates on the present utility model in conjunction with the embodiments in the accompanying drawings, but it does not constitute any limitation to the present utility model.

Specific embodiments
[0013] Refer to Figure 1-2 As shown, a fiber optic positioning device for a transmission shaft of the present utility model includes a base 1, a positioning seat 2 is provided on the base 1, and an electronic control assembly 3 is provided on the base 1; a mounting seat 4 is provided on one side of the positioning seat 2, and a mounting cylinder 5 is horizontally provided on the mounting seat 4; a positioning shaft 7 adapted to the transmission shaft is provided in the mounting cylinder 5 through an elastic component 6, and opposed fiber optics 8 are provided on the upper and lower side walls of the mounting cylinder 5. The transmission shaft cooperates with the positioning shaft to make the pin hole located at the position of the opposed fiber optics and start to rotate slowly. When the pin hole rotates to be perpendicular to the bottom surface of the box body, the opposed fiber optics pass through the pin hole, and the electronic control assembly cuts off the power supply of the transmission to stop the rotation so that the pin hole remains in a vertical state.
[0014] In the initial state, the front end of the positioning shaft is blocked between the opposed fiber optics, cutting off the opposed signal of the opposed fiber optics. When the transmission shaft cooperates with the positioning shaft, the positioning shaft is pushed into the mounting seat, making the shaft located between the opposed fiber optics. When the transmission is removed, the positioning shaft rebounds to the initial position under the action of the elastic component, cutting off the opposed signal of the opposed fiber optics.
[0015] In this embodiment, the elastic component 6 includes a guide groove 6a provided on the mounting seat 4, and a piston ring 6b adapted to the guide groove 6a is provided on the positioning shaft 7; a return spring 6c is sleeved on the positioning shaft 7 between the piston ring 6b and the inner bottom surface of the guide groove 6a, and a limit ring 6d adapted to the piston ring 6b is provided at the front end of the guide groove 6a.
[0016] In this embodiment, preferably, the positioning seat 2 includes a guide rail 2a provided on the base 1. A sliding seat 2b for placing the gearbox is provided on the guide rail 2a, and a positioning component for fixing the sliding seat 2b is provided on the guide rail 2a. A placement groove adapted to the base of the gearbox is provided on the sliding seat. In order to maintain the stability of the gearbox during operation, a corresponding quick-lock component can be provided on the sliding seat. With this structure, it is convenient to move the gearbox so that the rotating shaft contacts and cooperates with the positioning shaft.
[0017] In this embodiment, the electric control component 3 includes a control host 3a provided on the base 1. A control main board and a power supply are provided inside the control host 3a, and a buzzer 3b connected to the control main board is provided on the control host 3a; a power plug 3c for supplying power to the gearbox is connected to the control host 3a. When the pin hole rotates to be perpendicular to the bottom plate surface of the box body so that the opposed optical fiber passes through the pin hole, the control main board receives the signal of the opposed optical fiber to make the buzzer alarm to remind the operator, and at the same time cuts off the power supply of the gearbox to make it stop running.
[0018] During use, place the gearbox on the sliding seat with the rotating shaft of the gearbox facing the positioning shaft. Push the gearbox until the rotating shaft cooperates with the positioning shaft and the position where the pin hole is located is between the opposed optical fibers. Plug the power plug into the gearbox, start the power supply to make the rotating shaft rotate slowly. When the pin hole rotates to be perpendicular to the bottom plate surface of the box body, the opposed optical fiber passes through the pin hole. The control main board receives the signal of the opposed optical fiber to make the buzzer alarm to remind the operator, and at the same time cuts off the power supply of the gearbox to make it stop running, so that the pin hole remains in a vertical state.
