[0017] A method for using a drilling and tapping machine for machining: The specific steps are as follows:

[0018] S1. First, the pneumatic components are activated. Cylinder 1 pushes sealing plug 3. Sealing plug 3 moves within sealing sleeve 2. The hydraulic oil filling sealing sleeve 2 pushes sealing plug 4 to move, which in turn pushes the rotating plate to move. This causes multiple sealing plugs 2 to slide within sealing sleeve 1. The hydraulic oil filling sealing sleeve 1 then drives sealing plug 1 and clamping plate 1 to move towards the sleeve, clamping and fixing the sleeve, thus completing the installation of the sleeve and the drill bit.

[0019] S2, next, place the workpiece on the base plate, start motor two to drive clamping plate two to rotate to a suitable position on the upper end of the workpiece, shorten cylinder three to drive the mounting plate to move down, so that clamping plate two limits and fixes the workpiece, then start motor three, drive the slider to move through ball screw and nut seat, thereby driving the base plate and workpiece to the processing position, finally start motor four, drive the base plate to rotate through drive shaft two, and perform multi-face drilling and tapping work on the workpiece;

[0020] S3. Finally, start motor one, which drives the fixed sleeve to rotate through the transmission assembly, drives the sleeve to rotate through clamping plate one, and then drives the drill bit to rotate. The electric telescopic column pushes the drill bit forward to complete the drilling and tapping work on the workpiece.

[0021] This invention integrates key components for drilling and tapping, such as motor one, transmission components, fixed sleeve, sleeve, and drill bit in the drilling unit, and motor two, motor three, motor four and related moving and clamping structures in the processing unit, into a single machine tool. During equipment operation, all components work together. The transmission components ensure stable power transmission in the drilling unit, and the motors and moving structures in the processing unit cooperate to enable precise workpiece positioning and multi-faceted processing. In different working conditions, it eliminates the need to process workpieces between different devices as in traditional methods, reducing the space occupied by the equipment, as well as the time spent on workpiece movement and installation and debugging. This reduces time loss during workpiece transfer, significantly improves processing efficiency, saves workshop space, and optimizes workshop layout.

[0022] During installation, all components of this invention, such as clamping plate one, sealing plug one, sealing sleeve one, sealing plug two, rotating plate, and pneumatic components including cylinder one, sealing plug three, sealing sleeve two, sealing plug four, and bearings, fit together tightly. When debugging or replacing components, activating cylinder one allows clamping plate one to clamp and release the sleeve. In actual processing, when it is necessary to replace the drill bit, compared to the traditional method of using wrenches and other tools to remove multiple fastening bolts, which is cumbersome and time-consuming, this equipment only requires activating cylinder one, and the action of clamping plate one can be completed within a few seconds, thus achieving rapid replacement of the drill bit. For processing tasks that require frequent tool changes, such as processing workpieces with different thread specifications, this greatly reduces equipment downtime, increases the effective working time of the equipment, and significantly improves production progress.

[0023] The processing unit of this invention features multiple adjustment and movement structures. The clamping plate two, which works in conjunction with motor two and cylinder three, can be adjusted in angle and position. In actual processing, it can firmly clamp workpieces of various shapes, including round, square, and irregular shapes. The moving assembly, consisting of motor three, ball screw, and nut seat, can move workpieces of different sizes to the processing position. Motor four drives the base plate to rotate, enabling multi-faceted processing of the workpiece. When processing parts, the drill bit position can be adjusted according to the size and shape of the part using the adjustment assembly. Utilizing the flexible clamping and movement functions of the processing unit, diverse processing can be achieved. When processing large workpieces, it can withstand the weight and processing forces, ensuring processing stability and reliability, and meeting the diverse processing needs of the machining industry. Whether for single-piece or small-batch production or batch production of workpieces of different specifications, it can efficiently and accurately complete processing tasks.

The motor 24 is slidably installed at one end of the machine tool 1. The motor 24 is linked to the fixed sleeve 26 through the transmission assembly 25. When the motor 24 is started, it drives the fixed sleeve 26 to rotate. The electric telescopic column 21 is installed inside the sleeve 20. The drill bit 23 is threadedly connected to the other end of the electric telescopic column 21 through the threaded column 22.

[0045] And processing unit 3, which is located inside the bottom end of machine tool 1, is used to install and move workpiece 4.

[0046] The replacement component 27 includes a clamping plate 270, a limiting member 271, a sealing plug 272, a sealing sleeve 273, a sealing plug 274, a rotating plate 275, and a pneumatic component 276. A plurality of clamping plates 270 are slidably arranged at one end of the fixed sleeve 26. One end of each clamping plate 270 is connected to a sealing plug 272 via the limiting member 271. The other end of the sealing plug 272 slides within the sealing sleeve 273. A sealing plug 274 is slidably arranged at the other end of the sealing sleeve 273. The sealing sleeve 273 is fixedly installed on the fixed sleeve 276. Inside 6, a rotating plate 275 is fixedly connected to the other end of the sealing plug 274. The rotating plate 275 is horizontally slidably connected to the inner wall of the fixed sleeve 26. Specifically, the inner wall of the fixed sleeve is provided with several limiting grooves 3 that are consistent with the moving direction of the sealing plug 2761. A limiting block that matches the limiting groove 3 is fixedly connected to the outer wall of the rotating plate 275. The limiting block is slidably connected to the limiting groove 3, thereby limiting the sliding position of the rotating plate 275. At the same time, the rotation of the fixed sleeve 26 can also drive the rotating plate 275 to rotate. A pneumatic component 276 is rotatably provided at the other end of the rotating plate 275.

[0047] The limiting component 271 includes an opening 2710 and a limiting plate 2711. The wall of the fixing sleeve 26 has several equally spaced openings 2710. The limiting plate 2711 is slidably connected inside the opening 2710. One end of the limiting plate 2711 is fixedly connected to the clamping plate 270, and the other end of the limiting plate 2711 is fixedly connected to the sealing plug 272.

[0048] The pneumatic component 276 includes a cylinder 2760, a sealing plug 2761, a sealing sleeve 2762, a sealing plug 2763, and a bearing 2764. The cylinder 2760 is slidably mounted on one end of the machine tool 1. The output shaft of the cylinder 2760 is fixedly connected to the sealing plug 2761. The sealing plug 2761 is movably connected to the fixed sleeve 26. One end of the sealing plug 2761 is slidably disposed inside the sealing sleeve 2762. The other end of the sealing sleeve 2762 is slidably provided with the sealing plug 2763. The other end of the sealing plug 2763 is rotatably connected to the bearing 2764. The bearing 2764 is fixedly connected to one end of the rotating plate 275. The cylinder 2760 and the motor 24 are both mounted on the base 2765.

[0049] When in use, start cylinder 2760. The output shaft of cylinder 2760 pushes sealing plug 2761 to slide inside fixed sleeve 26. Sealing plug 2761 squeezes hydraulic oil inside sealing sleeve 2762. The hydraulic oil pressure is transmitted to sealing sleeve 273, pushing sealing plug 274 to move. Sealing plug 274 drives rotating plate 275 to rotate. When rotating plate 275 rotates, it drives clamping plate 270 to slide through limiting component 271. Clamping plate 270 loosens its grip on sleeve 20, and sleeve 20 is taken out. Then, the drill bit 23 can be replaced or maintained. After that, sleeve 20 is placed between clamping plates 270, and cylinder 2760 is operated in reverse to make clamping plate 270 re-clamp sleeve 20, completing the installation of the replaced or maintained drill bit 23.

[0050] The transmission assembly 25 includes a drive shaft 250, a transmission wheel, and a transmission chain 251. The drive shaft 250 is fixedly connected to the output shaft of the motor 24. The drive shaft 250 and the outer wall of the fixed sleeve 26 are both fixedly connected to the transmission wheel. The two transmission wheels are connected by the transmission chain 251. The sealing sleeve 273 and the sealing sleeve 2762 are both filled with hydraulic oil. When the motor 24 is started, the drive shaft 250 is rotated, which in turn drives the fixed sleeve 26 to rotate through the transmission wheel and the transmission chain 251. This causes the rotating plate 275 to rotate, which in turn drives the sleeve 20 to rotate through the clamping plate 270. This causes the drill bit 23 to rotate and perform drilling and tapping work on the workpiece 4. The electric telescopic column 21 can adjust the position of the drill bit 23. The hydraulic oil in the sealing sleeve 273 is filled between the sealing plug 272 and the sealing plug 274, while the hydraulic oil in the sealing sleeve 2762 is filled between the sealing plug 2761 and the sealing plug 2763.

Two symmetrically distributed limiting plates 284 are fixedly connected. One end of cylinder 282 is fixedly connected to the limiting plate 284. Two symmetrically distributed limiting grooves 283 are opened on both sides of the slide plate 281. The two limiting plates 284 are slidably disposed in the limiting grooves 283. When in use, the cylinder 282 is shortened, which can drive the slide plate 281 to slide upward, thereby driving the fixed sleeve 26 and motor 24 to slide upward, completing the adjustment of the vertical position of the drill bit 23, and also increasing the convenience of replacing the drill bit 23.

[0052] The processing unit 3 includes a base 30, a slider 31, a base plate 32, a cylinder 33, a mounting plate 34, a motor 35, a clamping plate 36, and a moving assembly 37. The base 30 is fixedly installed at the bottom of the machine tool 1. A slider 31 is slidably connected inside the base 30. The base plate 32 rotates to the upper end of the slider 31. Two cylinders 33 are fixedly installed on the upper end of the base plate 32. The mounting plate 34 is fixedly connected to the output shaft of each cylinder 33. A motor 35 is mounted on the mounting plate 34. The output shaft of the motor 35 is fixedly connected to the clamping plate 36. The clamping plate 36 limits and fixes the workpiece 4 on the base plate 32. The base plate 32 moves by... The moving component 37 drives the workpiece 4 to move and place it on the base plate 32. The cylinder 33 is started, and the output shaft of the cylinder 33 extends, driving the mounting plate 34 and the clamping plate 36 to descend. The clamping plate 36 limits and fixes the workpiece 4. According to the processing needs, the motor 370 is started, and the motor 370 drives the ball screw 371 to rotate. The ball screw 371 drives the slider 31 to move within the base 30 through the nut seat 372, thereby driving the base plate 32 and the workpiece 4 to move. If it is necessary to adjust the angle of the workpiece 4, the motor 473 is started, and the motor 473 drives the base plate 32 to rotate through the drive shaft 374.

[0053] The moving component 37 includes a third motor 370, a ball screw 371, a nut seat 372, a cavity, a fourth motor 373, and a second drive shaft 374. The third motor 370 is installed on the inner wall of the machine tool 1. The output shaft of the third motor 370 is fixedly connected to the ball screw 371. The ball screw 371 is threadedly connected to the nut seat 372. The slider 31 is fixedly connected to the nut seat 372. The slider 31 has a cavity. The fourth motor 373 is installed in the cavity.

The limiting posts 39 are slidably connected to the limiting groove 38. When the motor 370 is started, the output shaft of the motor 370 drives the ball screw 371 to rotate. The ball screw 371 cooperates with the nut seat 372 to convert the rotational motion into linear motion, so that the slider 31 moves horizontally within the base 30. When it is necessary to adjust the angle of the base plate 32, the motor 4 373 is started. The output shaft of the motor 4 373 drives the drive shaft 374 to rotate. The drive shaft 374 drives the base plate 32 to rotate. During the movement and rotation, the sliding of the limiting posts 39 within the limiting groove 38 ensures that the movement of the base plate 32 is stable and accurate.

[0055] A method for using a drilling and tapping machine for machining: The specific steps are as follows:

[0056] S1. First, start the pneumatic component 276. Cylinder 1 2760 pushes sealing plug 3 2761. Sealing plug 3 2761 moves inside sealing sleeve 2 2762. The hydraulic oil filled inside sealing sleeve 2 2762 pushes sealing plug 4 2763 to move, which in turn pushes rotating plate 275 to move. This causes multiple sealing plugs 2 274 to slide inside sealing sleeve 1 273. The hydraulic oil filled inside sealing sleeve 1 273 then drives sealing plug 1 272 and clamping plate 1 270 to move towards sleeve 20, clamping and fixing sleeve 20, thus completing the installation of sleeve 20 and the installation of drill bit 23. When drill bit 23 needs to be replaced later, simply shorten cylinder 1 2760. Similarly, this causes multiple clamping plates 1 270 to loosen sleeve 20, thus disassembling sleeve 20. Then, drill bit 23 can be separated from sleeve 20 to complete the replacement or maintenance of drill bit 23.

[0057] S2, next, place the workpiece 4 on the base plate 32, start the second motor 35 to drive the second clamping plate 36 to rotate to a suitable position on the upper end of the workpiece 4, and shorten the third cylinder 33 to drive the mounting plate 34 to move down, so that the second clamping plate 36 limits and fixes the workpiece 4. Then, the third motor 370 starts, and drives the slider 31 to move through the ball screw 371 and the nut seat 372, thereby driving the base plate 32 and the workpiece 4 to move to the processing position. Finally, the fourth motor 373 starts, and drives the base plate 32 to rotate through the second drive shaft 374 to perform multi-face drilling and tapping work on the workpiece 4.

[0058] S3. Finally, start motor 24, which drives fixed sleeve 26 to rotate through transmission component 25. The rotation of fixed sleeve 26 drives rotating plate 275 that slides horizontally with it to rotate, and also drives limit plate 2711 to rotate synchronously. Thus, clamping plate 270 drives sleeve 20 to rotate, which in turn drives drill bit 23 to rotate. Electric telescopic column 21 pushes drill bit 23 forward to complete the drilling and tapping work on workpiece 4.

[0059] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
