[0020] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment: As Figures 1-4 shown, the present utility model provides a drilling machine for PCB circuit boards, including a machine base 1. One side of the top end of the machine base 1 is fixedly connected with a mounting frame 2. A transverse moving component 3 is arranged on one side of the mounting frame 2. A moving seat 4 is arranged on the transverse moving component 3. One side of the bottom of the moving seat 4 is fixedly connected with a mounting plate 6. An electric cylinder 5 is fixedly installed on the top end of the mounting plate 6. The piston rod of the electric cylinder 5 extends to the bottom end of the mounting plate 6 and is fixedly connected with a fixed seat 7. The fixed seat 7 forms a 45-degree inclination angle with the electric cylinder 5. The bottom end of the fixed seat 7 is rotatably connected with a rotating seat 8. The bottom end of the rotating seat 8 is fixedly installed with servo motors 9 distributed symmetrically about the center. The driving end of the servo motor 9 is fixedly connected with a connecting seat 10. A drill bit 12 is arranged on one side of the connecting seat 10. A clamping component is arranged between the drill bit 12 and the connecting seat 10. The middle part of the top end of the fixed seat 7 is fixedly installed with a connecting seat 10. The driving end of the connecting seat 10 is fixedly connected with the rotating seat 8.

[0022] The clamping component includes a slot 11 which is opened at the bottom end of the connecting seat 10. A conical block 13 is fixedly connected to the top end of the drill bit 12. Inside the connecting seat 10 and on both sides of the slot 11, there are sliding grooves 14. A clamping block 16 is slidably clamped inside the sliding groove 14, and the clamping block 16 is mutually clamped with the conical block 13.

[0023] By adopting the above technical solution, when installing the drill bit 12, the conical block 13 at the top end of the drill bit 12 is inserted into the slot 11, and the clamping block 16 is mutually clamped with the conical block 13, so as to vertically limit the drill bit 12.

[0024] A placement plate 21 is slidably clamped at the top end of the machine base 1. Symmetrically distributed sliders 22 are fixedly connected to the bottom end of the placement plate 21. A through groove 23 is opened at the top end of the machine base 1, and the sliders 22 are slidably clamped in the through groove 23. On one side of the inner wall of the machine base 1, an electric telescopic rod 24 is fixedly installed. The piston rod of the electric telescopic rod 24 is fixedly connected to an L-shaped plate 25, and the slider 22 and the L-shaped plate 25 are fixedly connected.

[0025] By adopting the above technical solution, the PCB circuit board is placed on the top end of the placement plate 21. Through the telescopic movement of the piston rod of the electric telescopic rod 24, the L-shaped plate 25 is pushed to move longitudinally, thereby driving the placement plate 21 to move longitudinally and cooperating with the transverse movement assembly 3 to move, which is convenient for drilling operations at different positions of the PCB circuit board.

[0026] On both sides of the clamping block 16 that are far away from each other, telescopic rods 15 are fixedly connected. The ends of the telescopic rods 15 that are far away from each other extend to the outside of the connecting seat 10 and are fixedly connected to a pull rod 18.

[0027] By adopting the above technical solution, by simultaneously pulling the pull rods 18 to both sides, the two clamping blocks 16 are driven to move synchronously, so that the conical block 13 and the clamping block 16 are no longer clamped, thereby releasing the restriction on the vertical movement of the conical block 13, which is convenient for pulling out the conical block 13 from the slot 11 to replace the drill bit 12.

[0028] Between the sides of the clamping block 16 that are far away from each other and the inner wall of the sliding groove 14, a spring 17 is arranged. The spring 17 is movably sleeved on the outside of the telescopic rod 15.

[0029] By adopting the above technical solution, by arranging the spring 17, it is convenient to reset the clamping block 16.

[0030] Two symmetrically distributed guide blocks 20 are fixedly connected to the bottom end of the placement plate 21. Two symmetrically distributed guide grooves 19 are opened on the outside of the drill bit 12, and the guide blocks 20 are slidably clamped in the guide grooves 19.

[0031] By adopting the above technical solution, through the cooperation between the guiding block 20 and the guiding groove 19, it is convenient to guide the installation of the drill bit 12. At the same time, the rotation of the drill bit 12 is limited.

[0032] On one side where the bottom ends of the clamping blocks 16 are close to each other, they are both set as inclined surfaces.

[0033] By adopting the above technical solution, by setting the sides where the bottom ends of the clamping blocks 16 are close to each other as inclined surfaces, it is convenient to better install the drill bit 12.

[0034] Working principle: When drilling holes in the PCB circuit board, by placing the PCB circuit board on the top of the placing board 21, through the telescopic movement of the piston rod of the electric telescopic rod 24, the L-shaped plate 25 is pushed to move longitudinally, thereby driving the placing board 21 to move longitudinally, and cooperating with the transverse movement assembly 3 to move, which is convenient for drilling holes at different positions of the PCB circuit board;

[0035] When drilling holes with different hole diameters, the rotating seat 8 is driven to rotate by the connecting seat 10, and at the same time, the servo motor 9 is driven to rotate, so that the servo motor 9 is in a vertical state, thereby switching the drill bit 12 to meet the drilling requirements for different hole diameters. And when the drill bit 12 needs to be replaced, by pulling the pull rods 18 towards both sides simultaneously, the two clamping blocks 16 are driven to move synchronously, so that the conical block 13 is no longer clamped with the clamping block 16, thereby releasing the restriction on the vertical movement of the conical block 13, and then the conical block 13 is pulled out from the inside of the slot 11 to replace the drill bit 12. During installation, the conical block 13 at the top of the drill bit 12 is inserted into the inside of the slot 11, and the clamping block 16 is clamped with the conical block 13, thereby limiting the drill bit 12 vertically.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these changes and modifications.
