Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: a drill bit switching structure, including: a horizontal double-head drill press 1; a drill bit feed frame 2 is arranged on the top of the horizontal double-head drill press 1; a fixed side plate 3 is fixedly connected to one side of the drill bit feed frame 2; an outer movable sleeve 4 is movably arranged outside the fixed side plate 3; fixed brackets 20 are fixedly connected at equal intervals on one side of the outer movable sleeve 4; a drill pipe 9 is movably arranged inside the fixed brackets 20; a connecting rod 8 is fixedly connected to one end of the drill pipe 9, and the connecting rod 8 is movably connected to the outer movable sleeve 4; storage grooves 19 are opened at equal intervals inside the fixed side plate 3, and the storage grooves 19 cooperate with the connecting rod 8; a rotating cylinder 11 is movably arranged in one of the storage grooves 19; a fixed sleeve 16 is slidably arranged outside the fixed sleeve 16; one end of a driving shaft 18 is fixedly connected to the fixed sleeve 16;

[0031] The drill feed frame 2 converts the rotational motion of the motor into the linear feed motion of the drill feed frame 2 through the ball screw inside the horizontal double-head drill press 1, and drives each drill pipe 9 and the drill bit body 22 to move through the drill feed frame 2 to complete the drilling work.

[0032] It can be understood that in the present utility model, when replacing the drill bit body 22, the output end of the first motor 5 drives the rotating inner disc 6 to rotate. When the rotating inner disc 6 rotates, the outer movable sleeve 4 is driven to rotate and adjust by the cylinder 7. When the outer movable sleeve 4 rotates, it drives each fixed bracket 20, drill pipe 9 and drill bit body 22 on one side to rotate and adjust. The drill bit body 22 and the drive shaft 18 are selected to be in the same horizontal position. The output end of the cylinder 7 drives the outer movable sleeve 4 to move towards the side of the fixed side disc 3. One end of the connecting rod 8 of the drill pipe 9 enters the receiving groove 19, and is pushed against one side of the rotating cylinder 11 through each outer limiting groove 10 on the outside of the connecting rod 8. When the outer limiting groove 10 and the limiting clamping plate 12 are not aligned, the connecting rod 8 cannot enter the rotating cylinder 11 for limit installation. At this time, the connecting rod 8 pushes one end of the rotating cylinder 11, and the rotating cylinder 11 drives the limiting slider 14 to slide in the inner limiting chute 15. At this time, the rotating cylinder 11 presses the spring 17. By manually rotating the auxiliary rotating sleeve 21 on the outside of the drill pipe 9, the rotation of the drill pipe 9 is completed. When the drill pipe 9 rotates, it drives the connecting rod 8 at one end to rotate, and the connecting rod 8 drives the outer limiting groove 10 on the outside to rotate. Manually slightly rotate the auxiliary rotating sleeve 21 and observe the position of the rotating cylinder 11. When the outer limiting groove 10 and the limiting clamping plate 12 are positioned and matched, the spring 17 will reset and drive the rotating cylinder 11 to move towards one end of the connecting rod 8. Stop rotating the auxiliary rotating sleeve 21. The rotating cylinder 11 reaches the outside of the connecting rod 8, and each limiting clamping plate 12 inside the rotating cylinder 11 is fixedly limited with each outer limiting groove 10 on the outside of the connecting rod 8. The drive shaft 18 is driven by the output end of the drive motor on the drill feed frame 2. When the drive shaft 18 rotates, it drives the fixed sleeve 16 to rotate. When the fixed sleeve 16 rotates, it drives the inner limiting chute 15 inside to rotate. When the inner limiting chute 15 rotates, it drives each limiting slider 14 sliding internally to rotate. When the limiting slider 14 rotates, it drives the rotating cylinder 11 inside to rotate. When the rotating cylinder 11 rotates, it drives each limiting clamping plate 12 inside to drive the outer limiting groove 10 to rotate. When the outer limiting groove 10 rotates, it drives the connecting rod 8 to rotate, so as to complete the rotation of the connecting rod 8 driving the drill pipe 9 and the drill bit body 22 after installation. The drill pipe 9 and the drill bit body 22 are moved through the horizontal double-head drill press 1 for drilling treatment.

When the output end of the first motor 5 drives the rotating inner disc 6 to rotate, the rotating inner disc 6 will drive the outer movable sleeve 4 to rotate outside the fixed side disc 3 through the cylinder 7, so as to adjust the positions of the drill pipes 9 and the drill bit body 22.

When the limiting sliders 14 rotate, they drive the rotating cylinder 11 to rotate synchronously.
