[0017] Please refer to Figure 1 - Figure 2, the present utility model provides a technical solution: an adjustable optical waveguide structure for laser micromachining, including a mirror body 1. One end of the mirror body 1 is horizontally and fixedly installed with a first adjusting rod 11. It also includes a mounting seat 12, a large bevel gear 14 and a small bevel gear 17. An adjusting groove 13 is formed inside the mounting seat 12. The first adjusting rod 11 is rotationally connected to the inner walls on both sides of the adjusting groove 13 through bearings. The first adjusting rod 11 horizontally penetrates through the middle of the large bevel gear 14 and is fixedly connected to the large bevel gear 14. Above the mounting seat 12, a motor 15 is fixedly connected by bolts. The shaft end of the motor 15 is fixedly connected with a second adjusting rod 16. The second adjusting rod 16 is rotationally connected to the top inner wall of the adjusting groove 13 through a bearing. The bottom end of the second adjusting rod 16 is fixedly connected to the middle of the small bevel gear 17. The large bevel gear 14 meshes with the small bevel gear 17, and the sizes of the large bevel gear 14 and the small bevel gear 17 are matched.
[0018] In this technical solution, the mounting seat 12 is fixed at a specified position by screws. When it is necessary to adjust the use angle of the mirror body 1, the motor 15 is controlled to work through the controller 22. The second adjusting rod 16 can drive the small bevel gear 17 to rotate. Through the meshing of the small bevel gear 17 and the large bevel gear 14, during the rotation of the small bevel gear 17, the large bevel gear 14 can be driven to rotate. Through the first adjusting rod 11, the mirror body 1 can be driven to rotate stably to adjust the use angle.
[0019] In this embodiment, a magnet 2 is fixedly connected to the outer side of the second adjusting rod 16. The magnets 2 are evenly distributed in a ring on the outer side of the second adjusting rod 16. The upper end of one inner wall of the adjusting groove 13 is fixedly connected with a Hall sensor 21.
[0020] In this technical solution, when the motor 15 works and drives the second adjusting rod 16 to rotate, the magnet 2 on the outer side of the second adjusting rod 16 can be driven to rotate.
[0021] In this embodiment, the Hall sensor 21 corresponds to the magnet 2. The front side of the mounting seat 12 is fixedly connected with a controller 22. The data output end of the Hall sensor 21 is connected to the data input end of the controller 22. The signal output end of the controller 22 is connected to the signal input end of the motor 15.
[0022] In this technical solution, when the permanent magnet 2 rotates to the left side of the second adjusting rod 16, the permanent magnet 2 is horizontally aligned with the Hall sensor 21. Further, the Hall sensor 21 can transmit data to the controller 22, thereby detecting the number of rotations of the small bevel gear 17 and further accurately detecting the adjustment angle of the large bevel gear 14. During the rotation of the large bevel gear 14, the first adjusting rod 11 can drive the mirror body 1 to rotate for adjusting the use angle. When the mirror body 1 rotates to the specified position, the controller 22 can automatically control the motor 15 to stop working, thereby automatically adjusting the use angle of the mirror body 1, which is convenient and fast.
[0023] When an adjustable laser micromachining optical waveguide structure is in use, the mounting base 12 is fixed at a specified position by screws. When the use angle of the mirror body 1 needs to be adjusted, the controller 22 controls the motor 15 to work. The second adjusting rod 16 can drive the small bevel gear 17 to rotate. Through the meshing of the small bevel gear 17 and the large bevel gear 14, the rotation of the small bevel gear 17 can drive the large bevel gear 14 to rotate. When the motor 15 works and drives the second adjusting rod 16 to rotate, the permanent magnet 2 outside the second adjusting rod 16 can be driven to rotate. When the permanent magnet 2 rotates to the left side of the second adjusting rod 16, the permanent magnet 2 is horizontally aligned with the Hall sensor 21. Further, the Hall sensor 21 can transmit data to the controller 22, thereby detecting the number of rotations of the small bevel gear 17 and further accurately detecting the adjustment angle of the large bevel gear 14. During the rotation of the large bevel gear 14, the first adjusting rod 11 can drive the mirror body 1 to rotate for adjusting the use angle. When the mirror body 1 rotates to the specified position, the controller 22 can automatically control the motor 15 to stop working, thereby automatically adjusting the use angle of the mirror body 1, which is convenient and fast.
