AI Technical Summary
Existing precision machining drilling equipment for hardware parts struggles to achieve uniform support throughout the circumference when handling complex curved surfaces and irregularly shaped workpieces, resulting in problems such as large hole diameter errors, surface ripples, and cracks. Furthermore, traditional hydraulic support devices cannot dynamically adapt to the processing requirements of different hole diameters.
Using a hydraulic telescopic rod and a magnetically driven support, the support is pushed up by magnetic repulsion and liquid is injected to maintain stability. Combined with dynamic radius adjustment and liquid sealing control, it achieves ring-shaped support for the bottom of the workpiece, and the inner wall is polished by a grinding sleeve that expands with an airbag.
It enables stable drilling and dynamic hole diameter adaptation for complex workpieces, reduces hole diameter errors, improves machining accuracy and efficiency, and can automatically match the support radius of different hole diameters to ensure machining quality.

Abstract
Description
Technical Field
[0001] This invention relates to the field of machining technology, and in particular to a drilling and polishing combined machining equipment for precision machining of hardware parts. Background Technology
[0002] Drilling refers to the operation of creating holes in solid materials using a drill bit. This section describes drilling operations in exploration work, as well as the auxiliary tools needed for drilling and some emergency measures. Creating holes in solid materials using a drill bit is called drilling. Aside from some hole machining operations performed by machine tools such as lathes, boring machines, and milling machines, a large portion of hole machining for various parts is done by fitters using drilling machines and drilling tools (drill bits, reamers, etc.).
[0003] Referring to patent application CN119973646B, a drilling apparatus for producing metal parts is disclosed, comprising a frame, a clamping mechanism, a drilling mechanism, a dressing ring, and a transmission mechanism. The clamping mechanism holds the part body, and the drilling mechanism drills the part. During drilling, the transmission mechanism drives the dressing ring to rotate, keeping the dressing ring tangential to the drill bit, thereby straightening the part using the dressing ring. The dressing ring has a dressing blade on its peripheral wall facing the part body; during the rotation of the dressing ring, the dressing blade cuts burrs. Compared with existing technologies, this invention eliminates the need to remove the part from the processing platform before cutting burrs. After drilling thin plate parts, it also eliminates the need to remove them for deformation correction. While ensuring processing quality, it reduces the processing steps, thereby improving drilling efficiency.
[0004] In the field of precision machining of hardware parts, traditional drilling equipment generally uses rigid fixtures to fix the workpiece. This fixing method has significant limitations. When machining workpieces with complex curved surface structures such as turbine blades, rigid fixtures are difficult to provide uniform support for the bottom in the full circumference, which can easily lead to vibration and displacement during drilling. The hole diameter error is usually large. Especially for irregularly shaped workpieces with grooves, the contact surface of traditional fixtures is insufficient, resulting in obvious ripples or even cracks on the machined surface. Although existing technologies have attempted to use hydraulic support devices, they cannot dynamically adapt to the machining requirements of different hole diameters.
[0005] Therefore, it is necessary to provide a drilling and polishing combined processing equipment for precision machining of hardware parts to solve the above-mentioned technical problems. Summary of the Invention
[0006] The purpose of this invention is to provide a drilling and polishing combined processing equipment for precision machining of hardware parts, so as to solve the problems of the prior art mentioned in the background art.
[0007] Based on the above ideas, the present invention provides the following technical solution: a drilling and polishing combined processing equipment for precision machining of hardware parts, including a drilling machine, a hydraulic telescopic rod arranged on the outside of the drilling machine, a processing component arranged at the telescopic end of the hydraulic telescopic rod, and further comprising:
[0008] A drilling support table is disposed below the processing assembly, and a clamping assembly is provided on the top of the drilling support table;

[0014] As a further aspect of the present invention: the driving mechanism further includes a lead screw, which passes through the fixed frame and is rotatably connected to the fixed frame. The lead screw is connected to the moving plate through a ball nut pair. One end of each of the multiple lead screws is fixedly connected to a bevel gear. A bevel gear disk is meshed with the outer side of the multiple bevel gears. A micro motor is fixedly connected to the top of the gear disk. The output shaft of the micro motor is fixedly connected to the bevel gear disk.
[0015] As a further aspect of the present invention: a second gear is meshed with the outer side of the gear disk, the second gear is rotatably connected to the top of the drilling support platform, a first motor is fixedly connected to the outer side of the support frame, and the output shaft of the first motor is fixedly connected to the second gear.
[0016] As a further aspect of the present invention: the injection assembly includes a sealing disc, which is sleeved on the outside of multiple fixed cylinders and slidably connected to the multiple fixed cylinders; an electric push rod is fixedly connected to the top of the inside of the mounting frame, and the telescopic end of the electric push rod is fixedly connected to the sealing disc.
[0017] As a further aspect of the present invention: the injection assembly further includes a mounting frame, with the float slidably connected inside the mounting frame. When liquid is injected into the mounting frame, the float rises along the outside of the fixed cylinder under the action of liquid pressure and is slidably connected to the fixed cylinder. A placement plate for supporting the float is fixedly connected inside the mounting frame. A time-delay switch is provided at the top of the mounting frame, and the time-delay switch is electrically connected to an electric push rod. When the float rises and contacts the time-delay switch, the electric push rod is activated to drive the sealing plate to rise and close the connecting groove. A connecting ring is rotatably connected to the bottom of the mounting frame, and the connecting ring is connected to the external infusion tube.
[0018] As a further aspect of the present invention: a spiral groove is formed on the inner wall of the fixed cylinder; a protrusion is fixedly connected to the outer side of the rotating disk, the protrusion extends into the spiral groove and is slidably connected to the fixed cylinder; an airbag is fixedly connected to the outer side of the support column, and a grinding sleeve is fitted on the outer side of the airbag; a connecting plate is rotatably connected to the bottom of the mounting frame; an infusion tube is fixedly connected to the bottom of the connecting plate and is connected to an external air pump; a flexible tube is fixedly connected to the bottom of the rotating disk, the flexible tube passes through the mounting frame and extends into the connecting plate, one end of the flexible tube is connected to the airbag, and when gas is introduced into the airbag through the flexible tube, the airbag inflates; an external gear ring is fixedly connected to the outer side of the mounting frame, and a first gear is meshed with the outer side of the external gear ring; a second motor is fixedly connected to the outer side of the support frame, and the telescopic end of the second motor is fixedly connected to the first gear.

[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] 1. The drive process uses magnetic force to move and lift the support components. Due to the magnetic effect, multiple support components can fit against the bottom of the workpiece. After the fit is completed, liquid is injected into the mounting frame through the injection assembly, so that the support components can rise and remain stable. For different workpieces, the ring-shaped fit support is used at the location where drilling is required.
[0023] 2. The isolation strip blocks the radius of the drill hole, thereby isolating the magnetic repulsion between the electromagnet and the magnetic disk. Then, by starting the first motor, the output shaft of the first motor drives the second gear to rotate, and the second gear drives the gear disk to rotate. This causes the unblocked electromagnet to push multiple corresponding magnetic disks, thereby causing multiple contact heads to contact and adhere to the bottom of the workpiece. Through dynamic radius adjustment, it can be adapted to complex structures such as turbine blades. During continuous drilling, it automatically matches the support radius of different hole diameters.
[0024] 3. The connecting disc inflates the airbag through the flexible tube on the fixed cylinder, causing the airbag to expand. The expansion of the airbag opens the grinding sleeve, allowing it to fully contact the inner wall of the drilled hole. After the liquid inside the mounting frame is discharged, the mounting frame rotates, and the grinding sleeve fully contacts the inner wall of the drilled hole. The magnetic disc and electromagnet are alternately aligned, causing the magnetic disc to continuously rise and fall, performing multi-angle grinding of the burrs on the inner wall.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0039] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.
[0040] like Figures 1 to 11 As shown, a drilling and polishing combined processing equipment for precision machining of hardware parts includes the following embodiments:
[0041] Example 1: Includes a drilling machine 1, with a hydraulic telescopic rod 101 on its outer side. The telescopic end of the hydraulic telescopic rod 101 is equipped with a processing component, including a switching disc 2. Multiple drilling devices 201 and grinding devices 202 are arranged on the outer side of the switching disc 2. A support plate is provided at the telescopic end. The switching disc 2 is rotatably connected to the outer side of the support plate, and a drive motor is mounted on the support plate. Drilling is performed by the drilling devices 201. After drilling is completed, the drive motor drives the switching disc 2 to rotate and switch to the grinding devices 202. The grinding devices 202 then perform grinding treatment on the workpiece. The example also includes:
[0042] Drilling support table 3 is located below the processing component, and a clamping component is provided on the top of the drilling support table 3.
[0043] Support frame 4 is fixedly connected to the top of drilling support table 3. Support frame 4 is provided with a support mechanism for supporting the bottom of the workpiece. The support mechanism includes mounting frame 5, which is rotatably connected to the inside of support frame 4. Multiple support members are fixedly connected to the bottom of the inside of mounting frame 5, and the multiple support members are distributed in a ring around the center of mounting frame 5. A protective cover 401 is fixedly connected to the outside of support frame 4 for protection.
[0044] Gear disk 7 is rotatably connected to the bottom of the support frame 4, and a drive mechanism is provided on the top of gear disk 7. The drive mechanism is used to push the support member upward by magnetic repulsion.
[0045] The mounting frame 5 is equipped with a pressure injection component. When the support rises, the liquid injection component injects liquid into the support frame 4 to keep the support at the rising height.
[0046] In practice, when drilling a workpiece, the bottom of the workpiece is often suspended. A support device is used to support the bottom of the workpiece to ensure stability during drilling. However, due to the diverse shapes of workpieces, existing support devices cannot achieve a tight fit when the bottom is irregularly shaped, resulting in poor adaptability to irregularly shaped workpieces. Existing support devices are mostly rigid planes or fixed-height structures, unable to adapt to complex bottom contours such as curved surfaces or stepped shapes. There is also the risk of drilling deformation: uneven distribution of support force can easily cause localized stress concentration in the workpiece due to the cutting force of the drill bit, leading to deformation at the bottom of the drilled hole. Therefore, this solution uses a support frame 4 on top of the drilling support platform 3. Multiple support components in the mounting frame 5 inside the support frame 4 support the bottom of the workpiece. Through a driving process, the support components are moved and raised by magnetic force. Due to the magnetic effect, the multiple support components can fit against the bottom of the workpiece. After fitting, liquid is injected into the mounting frame 5 through a pressure injection component, allowing the support components to rise and remain stable. This provides annular fitting support for the drilling location of different workpieces.
[0047] Example 2: The support includes a fixed cylinder 6, which is fixedly connected to the bottom of the mounting frame 5. A magnetic disk 602 is slidably connected inside the fixed cylinder 6. A rotating disk 607 is rotatably connected to the top of the magnetic disk 602. A spring 603 is fixedly connected between the magnetic disk 602 and the bottom of the fixed cylinder 6. A support column 604 is fixedly connected to the top of the rotating disk 607. A contact head 605 is fixedly connected to the top of the support column 604. A connecting groove 601 is opened on the outside of the fixed cylinder 6. The connecting groove 601 is located at the magnetic disk 602. The magnetic disk 602 is used to seal and block the connecting groove 601.
[0048] In practice, when the drive mechanism at the bottom of the mounting frame 5 pushes the magnetic disk 602 inside the fixed cylinder 6 to rise through magnetic repulsion, the magnetic disk 602 drives the rotating disk 607 and the top support column 604 to rise, so that the contact head 605 fits against the bottom of the workpiece. The contact head 605 is equipped with a pressure sensor, which can monitor the pressure changes at various positions during drilling.
[0049] In this embodiment, the driving mechanism includes multiple fixed frames 9, which are arranged in a ring around the center of the gear disk 7. Multiple electromagnets 901 are fixedly connected inside each fixed frame 9. When the electromagnets 901 are energized, they repel the corresponding magnetic disks 602. A movable plate 903 is slidably connected inside the fixed frame 9. An insulating strip 904 is fixedly connected between the movable plate 903 and the end of the fixed frame 9 near the center. The insulating strip 904 is used to isolate the magnetic repulsion between the electromagnets 901 and the connecting groove 601.
[0050] The drive mechanism also includes a lead screw 902, which passes through the fixed frame 9 and is rotatably connected to the fixed frame 9. The lead screw 902 is connected to the moving plate 903 through a ball nut pair. One end of each of the multiple lead screws 902 is fixedly connected to a bevel gear 905. The outer sides of the multiple bevel gears 905 are meshed with a bevel gear disk 906. A micro motor is fixedly connected to the top of the gear disk 906. The output shaft of the micro motor is fixedly connected to the bevel gear disk 906.
[0051] A second gear 701 is meshed with the outer side of the gear disk 7. The second gear 701 is rotatably connected to the top of the drilling support platform 3. A first motor is fixedly connected to the outer side of the support frame 4. The output shaft of the first motor is fixedly connected to the second gear 701.
[0052] In practical implementation, when drilling the workpiece, the required hole diameter varies. To ensure that the support component supports the workpiece and avoids interference during drilling, the radius of the support component needs to be adjusted. Therefore, in this solution, multiple fixed frames 9 are set on the top of the gear disk 7, and multiple electromagnets 901 are fixedly connected inside the fixed frames 9. When the multiple electromagnets 901 are energized, the magnetic disk 602 inside the support frame 4, which is directly above the electromagnets 901, can be raised by magnetic force. When it is necessary to adjust the support radius, the micro motor is started, and the micro motor drives the moving plate 903 away from the center of the gear disk 7. The moving plate 903 causes the isolation strip 904 to unfold, blocking the radius of the drill hole and thus isolating the magnetic repulsion between the electromagnet 901 and the magnetic disk 602. Then, the first motor is started, and the output shaft of the first motor drives the second gear 701 to rotate. The second gear 701 drives the gear disk 7 to rotate, which in turn causes the unblocked electromagnet 901 to push multiple corresponding magnetic disks 602, thereby causing multiple contact heads 605 to contact and adhere to the bottom of the workpiece. Through dynamic radius adjustment, it can adapt to complex structures such as turbine blades with grooves. During continuous drilling, it automatically matches the support radius of different hole diameters.
[0053] Overall adjustment logic:
[0054] Support radius dynamic adjustment mechanism
[0055] Electromagnet array control: The partial lifting and lowering of the magnetic disk 602 is achieved by switching the electromagnet 901 inside the fixed frame 9 at the top of the gear disk 7 on and off. When the electromagnet is energized, it generates a magnetic repulsive force with a magnetic field strength of 0.1~0.3T, which pushes the magnetic disk upward;
[0056] Radius adjustment logic:
[0057] The micro motor drives the lead screw 902 to move the moving plate 903 radially, unfolding the insulating strip 904 to block the target area electromagnet 901 and block the transmission of magnetic force.
[0058] The unobstructed electromagnet continues to drive the support component upward, forming a ring-shaped support area with an adjustment accuracy of ±0.1mm.
[0059] Example 2: The injection assembly includes a sealing disc 504, which is sleeved on the outside of multiple fixed cylinders 6 and is slidably connected to the multiple fixed cylinders 6. An electric push rod 507 is fixedly connected to the top of the inside of the mounting frame 5, and the telescopic end of the electric push rod 507 is fixedly connected to the sealing disc 504.
[0060] The injection assembly also includes a mounting frame 5. A float 505 is slidably connected inside the mounting frame 5. When liquid is injected into the mounting frame 5, the float 505 rises along the outside of the fixed cylinder 6 under the action of liquid pressure and is slidably connected to the fixed cylinder 6. A placement plate 506 for supporting the float 505 is fixedly connected inside the mounting frame 5. A time delay switch is provided at the top inside the mounting frame 5. The time delay switch is electrically connected to the electric push rod 507. When the float 505 rises and contacts the time delay switch, the electric push rod 507 is activated to drive the sealing plate 504 to rise and close the connecting groove 601. A connecting ring 803 is rotatably connected to the bottom of the mounting frame 5. The connecting ring 803 is connected to the external infusion tube.
[0061] In practice, as the contact head 605 rises, liquid is injected into the connecting ring 803 through the infusion pipe 801. The liquid flows into the mounting frame 5. When the magnetic disk 602 inside the corresponding fixed cylinder 6 rises, the magnetic disk 602 exposes the connecting groove 601. At this time, a large amount of liquid enters the fixed cylinder 6 through the connecting groove 601. As the liquid continues to rise, it is continuously injected into the fixed cylinder 6 along with the rising magnetic disk 602. The stationary magnetic disk 602 seals the connecting groove 601, preventing liquid from entering. As the liquid inside the mounting frame 5 rises, it pushes the floating plate 505 to rise. After the floating plate 505 rises, it connects with the mounting frame 5. The time-delay switch at the top of the inner frame 5 is in contact and electrically connected to the electric push rod 507. After a period of contact, the electric push rod 507 pushes the sealing plate 504 to rise. The sealing plate 504 seals the connecting groove 601 on the outside of the multiple fixed cylinders 6, preventing liquid from being discharged from the inside of the fixed cylinders 6. The liquid ensures the rising distance of the magnetic disk 602, forming a stable support. In this scheme, a time-delay switch is used. After the liquid pushes the floating plate 505 to the top, the liquid continues to be injected, which can fully enter the inside of the fixed cylinder 6 and avoid gaps. After the liquid injection reaches a certain time, the gap of the fixed cylinder 6 will inevitably be filled after the magnetic disk 602 moves.
[0062] Additional information:
[0063] Liquid injection and magnetic disk linkage mechanism
[0064] Dynamic sealing control: When the magnetic disk 602 rises, the connecting groove 601 is exposed, allowing liquid to enter the fixed cylinder 6, while the magnetic disk that does not move remains sealed.
[0065] Floating disc trigger delay: The liquid pushes the floating disc 505 to rise to the contact delay switch with a delay range of 0.5 to 2 seconds, ensuring that the liquid fully fills the gap.
[0066] Delay switch function optimization
[0067] Dual protection design:
[0068] The time-delay switch, such as an electronic relay, activates the electric push rod 507 after the floating plate contacts, pushing the sealing plate 504 to close the connecting groove 601;
[0069] The delay parameter needs to be matched with the liquid flow rate of 0.8 to 1.2 L / min to avoid premature sealing and insufficient support.
[0070] Example 4: A spiral groove 608 is formed on the inner wall of the fixed cylinder 6. A protrusion is fixedly connected to the outer side of the rotating disk 607. The protrusion extends into the spiral groove 608 and is slidably connected to the fixed cylinder 6. An airbag 606 is fixedly connected to the outer side of the support column 604. A grinding sleeve 609 is fitted on the outer side of the airbag 606. A connecting disk 8 is rotatably connected to the bottom of the mounting frame 5. An infusion tube 801 is fixedly connected to the bottom of the connecting disk 8. The infusion tube 801 is connected to an external air pump. A flexible tube 610 is fixedly connected to the bottom of the rotating disk 607. The flexible tube 610 passes through the mounting frame 5 and extends into the interior of the connecting disk 8. One end of the flexible tube 610 is connected to the airbag 606. When gas is introduced into the airbag 606 through the flexible tube 610, the airbag 606 inflates. An external gear ring 501 is fixedly connected to the outer side of the mounting frame 5. A first gear 502 is meshed with the outer side of the external gear ring 501. A second motor 503 is fixedly connected to the outer side of the support frame 4. The telescopic end of the second motor 503 is fixedly connected to the first gear 502.
[0071] In practice, after drilling is completed, burrs remain at the drilled area of the workpiece, often requiring targeted grinding. In this solution, the contact heads 605 of multiple supports form a ring support around the drilled hole of the workpiece. At this time, by activating the micro motor, the micro motor drives the bevel gear disk 906, which in turn drives the meshing bevel gear 905 to rotate. This causes the bevel gear 905 to drive the lead screw 902 to rotate, thereby moving the isolation strip 904 on the moving plate 903, exposing the previously blocked electromagnet 901. The electromagnet 901 then pushes the previously unrisen magnetic disk 602 upwards. Because the connecting groove 601 is blocked, the liquid will not enter the fixed cylinder 6. When the magnetic disk 602... 2. When rising, the rotating disk 607 is pushed up. The rotating disk 607 rotates and rises along the spiral groove 608 inside the fixed cylinder 6 through the protrusion on the outside of the rotating disk 607. At the same time, the external air pump delivers gas into the connecting disk 8. The connecting disk 8 inflates the air bag 606 through the flexible tube 610 on the fixed cylinder 6, thereby causing the air bag 606 to expand. The expansion of the air bag 606 opens the grinding sleeve 609, so that the grinding sleeve 609 is in full contact with the inner wall of the drill hole. After the liquid inside the mounting frame 5 is discharged, the mounting frame 5 rotates. The grinding sleeve 609 is in full contact with the inner wall of the drill hole. The magnetic disk 602 and the electromagnet 901 are alternately aligned, so that the magnetic disk 602 continuously rises and falls, and performs multi-angle grinding of the burrs on the inner wall by rotating up and down.
[0072] Working principle of deburring system
[0073] Electromagnet and magnetic disk are linked: a micro motor drives the bevel gear disk 906 to rotate, which in turn drives the lead screw 902 to move through the bevel gear 905, thereby releasing the obstruction of the electromagnet 901 and pushing the magnetic disk 602 to rise.
[0074] Airbag grinding mechanism: The air pump inflates the airbag 606 through the flexible tube 610, causing the grinding sleeve 609 to expand and fit against the hole wall, and cooperate with the spiral groove 608 to achieve rotational lifting and grinding.
[0075] In this embodiment: two bidirectional lead screws 301, each of which is rotatably connected to a support plate on its outer side. The support plate is fixedly connected to the drilling support platform 3. Two clamping plates 302 are provided on the outer side of the bidirectional lead screws 301 and are connected to the clamping plates 302 by ball nuts.
[0076] In practice, when an external motor drives the bidirectional lead screw 301 to rotate, the bidirectional lead screw 301 drives the two clamping plates 302 to rotate relative to each other, thereby enabling the clamping plates 302 to stably clamp the workpiece.
