Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please refer to Figures 1-6 As shown; this utility model provides a drilling and tapping integrated machine technical solution: a drilling and tapping integrated machine includes a CNC moving machine tool 1, the CNC moving machine tool 1 is provided with a vertical moving end 101, a front-to-back moving end 102 and a horizontal moving end 103 provided on the front-to-back moving end 102, and also includes a processing rotation mechanism 2, a chip adsorption mechanism 3 and a workpiece fixing mechanism 4. The processing rotation mechanism 2 is provided on the vertical moving end 101, and a drilling module 5 and a tapping module 6 are respectively provided on the processing rotation mechanism 2. The processing rotation mechanism 2 can drive the drilling module 5 and the tapping module 6 to switch. The chip adsorption mechanism 3 is located on the horizontal moving end 103 to adsorb the chips generated by drilling and tapping. The workpiece fixing mechanism 4 is provided on the chip adsorption mechanism 3 to fix the position of the workpiece and rotate it.

[0024] The vertical moving end 101, the front-back moving end 102 and the horizontal moving end 103 on the CNC moving machine tool 1 can respectively drive the drilling module 5 and the tapping module 6 to move in the vertical, front-back and horizontal directions, and perform drilling and tapping operations on parts at different positions.

[0025] It should be noted that this device is designed for drilling and tapping parts on round tubes.

[0026] In this embodiment, refer to Figure 2 As shown, the machining rotation mechanism 2 includes a mounting frame 21, a stepper motor 22, a first pulley 23, a second pulley 24, a rotating shaft 25, and a mounting block 26. The mounting frame 21 is connected to the vertical moving end 101. The stepper motor 22 is located inside the mounting frame 21. The first pulley 23 is located on the main shaft of the stepper motor 22. The mounting block 26 is disposed on the rotating shaft 25 and is rotatably connected to the mounting frame 21 through the rotating shaft 25. The second pulley 24 is disposed at the end of the rotating shaft 25. A belt 20 is sleeved on the first pulley 23 and the second pulley 24.

[0027] In this embodiment, refer to Figure 2 As shown, the drilling module 5 and the tapping module 6 are vertically arranged at the top and bottom of the mounting block 26, respectively. A locking cylinder 27 is provided on the side wall of the mounting frame 21, and a locking rod 28 is provided on the telescopic end of the locking cylinder 27. A locking hole 29 (see reference) is provided on the side wall of the mounting block 26 to engage with the locking rod 28. Figure 3 (As shown).

[0028] It should be noted that the stepper motor 22 can be set by configuring the driver parameters and writing the control program so that the stepper motor 22 rotates 180 degrees forward or backward each time it receives a specific number of pulses, and locks itself after it stops rotating.

[0029] During drilling, the vertical moving end 101 moves the position of the mounting frame 21 downward, which in turn moves the drilling module 5 vertically downward to drill the part.

[0030] During tapping, the stepper motor 22 drives the first pulley 23 to rotate, which in turn drives the second pulley 24 to rotate via the belt 20. This causes the rotating shaft 25 to rotate on the mounting frame 21, which in turn rotates the mounting frame 21 180 degrees, positioning the tapping module 6 vertically at the bottom. Subsequently, the vertical moving end 101 moves the mounting frame 21 downwards to tap the part.

[0031] Since the drilling module 5 and the tapping module 6 are vertically positioned at the top and bottom of the mounting block 26, respectively, when tapping is performed after drilling the part, they will be at the same verticality, ensuring that the tapping and drilling are on the same center. This effectively avoids positional deviations caused by human error, minor equipment vibrations, or inaccurate workpiece clamping, thereby improving the coaxiality accuracy of the thread and the hole, ensuring processing quality, and ensuring that the drilling module 5 and the tapping module 6 are always perpendicular to the workpiece surface. This not only makes the drilled holes and tapped threads more regular, but also further improves concentricity and reduces eccentricity problems caused by tilting. Compensation can also be made within a certain range by rotation, thereby reducing the need for complex, high-precision tooling fixtures to ensure concentricity, reducing production costs and the difficulty of designing and manufacturing tooling fixtures.

[0032] After the position of the mounting frame 21 is rotated 180 degrees, the locking cylinder 27 drives the locking rod 28 to move horizontally into the locking hole 29 of the mounting block 26, thereby locking and fixing the position of the mounting block 26. This prevents the drilling module 5 or the tapping module 6 from shaking due to the shaking of the mounting block 26 during drilling or tapping, which would affect the accuracy of drilling or tapping.

[0033] In this embodiment, refer to Figure 4 As shown, the debris adsorption mechanism 3 includes a placement seat 31 disposed on a horizontally moving end, a placement groove inside the placement seat 31, a grid plate 32 on the top of the placement seat 31, and a cyclone debris adsorber 33 disposed in the placement groove.

[0034] During drilling and tapping, debris falls onto the grid plate 32. The cyclone debris adsorber 33 allows the debris-laden airflow to enter the cyclone adsorber tangentially, creating a high-speed rotating airflow. Under centrifugal force, the debris and other particles are thrown against the inner wall of the adsorber and slide down it, while the purified airflow is discharged upwards from the center of the adsorber, thus achieving the separation and collection of debris and airflow.

[0035] In this embodiment, refer to Figure 5 and Figure 6As shown, there are three workpiece fixing mechanisms 4, which are equally spaced on the top of the placement base 31. Each workpiece fixing mechanism 4 includes a first support 41, a second support 42, a moving electric cylinder 43, a mounting box 44, a drive motor 45, and a first rotating frustum 46. The first support 41 and the second support 42 are symmetrically arranged on both sides of the grid plate 32. The moving electric cylinder 43 is horizontally arranged on the first support 41. The mounting box 44 is connected to the telescopic end of the moving electric cylinder 43. The mounting box 44 is provided with a sliding rod 48 that slides with the first support 41. The drive motor 45 is located inside the mounting box 44. The first rotating frustum 46 is connected to the main shaft of the drive motor 45. The second support 42 is provided with a second rotating frustum 47.

[0036] When drilling and tapping the part, firstly, the moving electric cylinder 43 drives the mounting box 44 to move on the first support 41 via the slide rod 48, so that the first rotating platform 46 and the second rotating platform 47 are respectively located at both ends of the workpiece. Then, the moving electric cylinder 43 drives the mounting box 44 to move the first rotating platform 46 to the position of the second rotating platform 47, fixing the workpiece between the first rotating platform 46 and the second rotating platform 47. This achieves the goal of fixing the position of the workpiece when drilling and tapping, preventing the workpiece from shaking or wobbling during processing, which would affect the processing accuracy.

[0037] During processing, the drive motor 45 drives the first rotating platform 46 to rotate, which in turn causes the workpiece to drive the second rotating platform 47 to rotate on the second support 42. This causes the workpiece to rotate axially during drilling and tapping, allowing drilling and tapping to be performed on different positions of the workpiece. During drilling and tapping, the generated chips need to be discharged in time to avoid chip accumulation affecting the processing quality and tool life. When the workpiece rotates axially, it helps the chips to be discharged smoothly along the spiral direction, reducing scratches on the processed surface and improving the surface finish.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
