Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1 、 2 As shown in Figures 3, 4, and 5, the present invention provides a technical solution: a drilling machine with precise positioning, including: a workbench 1, a rotating table 21 is rotatably installed on the top of the workbench 1, four positioning components are arranged equidistantly on the top of the rotating table 21, the positioning component includes a support frame 11 fixedly connected to the top of the rotating table 21, a positioning disk 16 is threadedly connected to the top of the support frame 11, and lifting rods 14 are arranged on both sides of the positioning disk 16 in a lifting manner. The top of the lifting rod 14 is installed with a lifting pressure plate 15 through a fastening bolt for pressing workpieces with different diameters. A V-shaped groove 18 is fixedly connected to the side of the support frame 11 for positioning workpieces with circular and rectangular structures. A rotating pressure plate 19 for fixing the workpiece is rotatably connected to the middle of the V-shaped groove 18; a moving part is placed on the top of the workbench 1, and the moving part includes a first linear module 2 and a second linear module 3 for driving the drilling machine 7 to move along the X-axis and the Z-axis. A drilling machine 7 with adjustable angle is installed on the sliding table on one side of the second linear module 3. The drilling machine 7 is composed of a motor and a drill bit.

[0023] It should be noted that the utility model replaces a suitable positioning disk 16 according to the size of the aperture of the central workpiece. The positioning disk 16 is composed of a disk and a center column. A threaded rod that cooperates with the support frame 11 is provided at the bottom of the positioning disk 16. The positioning disk 16 is threadedly connected to the support frame 11. According to the size of the workpiece, the position of the lifting and pressing plate 15 on the lifting rod 14 is adjusted so that the lifting and pressing plate 15 can press the workpiece tightly. The hollow workpiece is sleeved on the outer side of the center column at the top of the positioning disk 16. The No. 1 cylinder 12 drives the lifting rod 14 to move downward, so that the lifting rod 14 drives the lifting and pressing plate 15 to move downward, so that the lifting and pressing plate 15 presses the workpiece tightly. The driving motor 8 drives the rotating table 21 to rotate, so that the No. 2 linear module 3 drives the punching machine 7 to move downward below the workpiece punching machine 7. To punch holes, when it is necessary to punch holes in a cylindrical or cubic structure, the mounting plate 4 is adjusted so that the punch 7 is perpendicular to the side of the support frame 11, and the position of the No. 2 linear module 3 is adjusted through the No. 1 linear module 2, and the workpiece is placed at the top of the V-groove 18. The cylinder is positioned at two points on the top of the V-groove 18. Since the middle part of the V-groove 18 is a right-angle structure, one corner of the rectangular workpiece is placed in the V-groove 18, and the No. 2 cylinder 17 is extended to support the bottom of the rotating pressure plate 19. Under the action of the lever principle, the rotating pressure plate 19 presses the workpiece, and the driving motor 8 drives the rotating table 21 to rotate, so that the punch 7 corresponds to the workpiece, and the No. 1 linear module 2 drives the No. 2 linear module 3 to move, and the No. 2 linear module 3 drives the punch 7 to move toward the workpiece to achieve punching.

[0024] See also Figure 2 As shown, a driving motor 8 is fixedly connected to the bottom of the workbench 1 , and an output end of the driving motor 8 is fixedly connected to the rotating table 21 .

[0025] It should be noted that the utility model is installed with a PLC controller, and an infrared sensor is installed vertically on the top of the workbench 1. A positioning metal plate that cooperates with the infrared sensor is installed on the outer side of the rotating table 21 corresponding to the position of the support frame 11. When the positioning metal plate corresponds to the infrared sensor, the support frame 11 moves to the specified position, and the sensor measures the environmental parameters, converts them into signals and sends them to the controller. The controller receives and processes the signals and generates corresponding control signals according to the preset control algorithm; the control signal is transmitted to the drive motor 8 through the output module, so as to control the drive motor 8 to rotate or stop, so as to facilitate the next step of punching.

[0026] See also Figure 3 , 5 As shown, a cylinder No. 1 12 is fixedly connected inside the support frame 11, and the output end of the cylinder No. 1 12 is fixedly connected to a lifting rod 14, and a limit block 13 slidably connected to a lifting plate 15 is fixedly connected to the top of the lifting rod 14.

[0027] It should be noted that a long strip-shaped hole is provided at the top of the lifting pressure plate 15 of the present utility model. The limit block 13 slides on the inner wall of the hole. The lifting pressure plate 15 is pressed and fixed on the top of the lifting rod 14 through a fastening screw. The first cylinder 12 drives the lifting rod 14 to lift and lower, so that there is a gap between the lifting pressure plate 15 and the top of the support frame 11. When the workpiece is placed on the top of the positioning disk 16, the first cylinder 12 is controlled by the control switch to pull the lifting rod 14 to move downward, so that the workpiece is squeezed and fixed between the lifting pressure plate 15 and the support frame 11, thereby realizing the fixation of the workpiece.

[0028] Please refer to Figure 1 、 3 As shown in the figure, a second cylinder 17 is installed inside the support frame 11 at a position corresponding to the rotary pressure plate 19, and a return spring 20 is installed between the rotary pressure plate 19 and the support frame 11.

[0029] It should be noted that when the second cylinder 17 of the present utility model extends and abuts against the bottom of the rotary pressure plate 19, one end of the rotary pressure plate 19 is pushed in a direction away from the support frame 11, so that the return spring 20 is stretched by the rotary pressure plate 19. Since the rotary pressure plate 19 is rotatably connected to the V-shaped groove 18, under the action of the lever principle, the other end of the rotary pressure plate 19 presses and fixes the workpiece. When the second cylinder 17 resets, one end of the rotary pressure plate 19 is pulled back to its original position by the pulling force of the return spring 20.

[0030] Please refer to Figure 1 、 2 As shown in Figures 3 and 4, the first linear module 2 is fixedly connected to the top of the workbench 1. The end of the second linear module 3 is fixedly connected to the moving slide of the first linear module 2. A mounting plate 4 is rotatably installed on the moving slide of the second linear module 3. A plurality of positioning holes 9 are equidistantly arranged in the middle of the mounting plate 4, and positioning bolts 10 are installed inside the positioning holes 9.

[0031] It should be noted that the first linear module 2 of the present utility model drives the second linear module 3 to move along the X-axis direction, and the second linear module 3 drives the drilling machine 7 to move along the Z-axis direction. When drilling the workpiece on the top of the support frame 11, the second linear module 3 is adjusted to a position directly opposite to the support frame 11, and the second linear module 3 drives the drilling machine 7 to move downward to drill holes. When drilling the workpiece on the side, the mounting plate 4 is rotated to a vertical state, and the angle is fixed by the cooperation of the positioning bolt 10 and the corresponding positioning hole 9. The height of the drilling machine 7 is adjusted according to the second linear module 3, and the first linear module 2 and the second linear module 3 drive the drilling machine 7 to move in a direction perpendicular to the workpiece, thereby completing the drilling.

[0032] Please refer to Figure 2 、 4As shown, one end of the mounting plate 4 is threadedly connected to an adjusting screw 6. The end of the adjusting screw 6 is rotatably connected to a fixing platform 5. The fixing platform 5 is slidably connected to the mounting plate 4. The drilling machine 7 is installed at the bottom of the fixing platform 5.

[0033] It should be noted that according to different drilling positions, the position of the drilling machine 7 inside the fixing platform 5 is adjusted in the present utility model. The adjusting screw 6 drives the fixing platform 5 to slide on the outside of the mounting plate 4, so as to adjust the position of the drilling machine 7 on the outside of the mounting plate 4, and the position of the drilling machine 7 in the Y-axis direction can be adjusted.
