Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and in particular to a rotary drilling and tapping cleaning device. Background Technology

[0002] In the mass production of hardware, die-cast parts, mechanical parts, and structural components, drilling and tapping are common and continuous machining processes. To improve production efficiency, existing equipment often employs rotary or multi-station circulating structures, allowing workpieces to pass sequentially through different machining stations on multiple fixed fixtures, thus achieving continuous switching between processes such as loading, positioning, drilling, tapping, and unloading. While this type of equipment has significant advantages in improving processing efficiency, after drilling and tapping, metal fragments, chips, and dust usually remain at the hole openings, thread locations, and workpiece surfaces. If not cleaned promptly, this can easily affect thread quality inspection, subsequent assembly, and the appearance of the finished product.

[0003] In existing technologies, some equipment sets up the cleaning process separately outside the machine, requiring manual labor or robotic arms to transfer the processed workpiece to a dedicated cleaning station for blowing, resulting in poor equipment flow coordination. Other solutions, while incorporating simple air-jet devices on the processing equipment, lack effective chip protection structures, allowing chips to be easily blown around the equipment during blowing, causing environmental pollution and secondary chip accumulation inside the equipment. This can also lead to chips re-adhering to the workpiece. Furthermore, insufficient transmission adaptability between conventional drilling or tapping mechanisms and tool clamping structures can also affect the stability of the machining station.

[0004] Therefore, it is necessary to provide a device that enables continuous drilling, tapping, and cleaning of workpieces within the same device, while also taking into account chip protection, nozzle adaptation and adjustment, and overall stability of the mechanism. Summary of the Invention

[0005] To solve the above problems, the present invention provides a rotary drilling, tapping and cleaning equipment that enables continuous drilling, tapping and cleaning operations, and has the advantages of compact structure, good cleaning effect and strong adaptability.

[0006] The technical solution adopted in this invention is: a rotary drilling, tapping, and cleaning device, comprising a frame, a rotary mechanism, a fixing fixture, multiple sets of drilling and tapping mechanisms, and a cleaning mechanism. The rotary mechanism is mounted on the frame, and multiple sets of fixing fixtures are arranged continuously along the rotation direction of the rotary mechanism. The multiple sets of drilling and tapping mechanisms are configured corresponding to multiple sets of fixing fixtures for drilling and / or tapping workpieces on the fixing fixtures. The cleaning mechanism is configured corresponding to the last set of fixing fixtures for cleaning the workpieces after drilling and / or tapping.

[0007] A further improvement to the above solution is that the cleaning mechanism includes a cleaning lifting module, a cleaning connection component, a cleaning protection component, a cleaning component, and a cleaning drive component. The cleaning lifting module is mounted on the frame, the cleaning connection component is mounted on the moving end of the cleaning lifting module, the cleaning protection component is connected to the cleaning connection component, the cleaning component is located above the cleaning protection component, and the cleaning drive component is mounted on the cleaning connection component.

[0008] A further improvement to the above solution is that the cleaning protection component includes a fixed frame and a flexible protective cover, one side of the fixed frame is connected to the cleaning connection component, and the flexible protective cover surrounds the outer periphery of the fixed frame.

[0009] A further improvement to the above solution is that the cleaning lifting module is used to drive the cleaning connecting assembly to move the cleaning protection assembly and the cleaning assembly toward the fixed fixture, so that the flexible protective cover is placed on the fixed fixture. The cleaning driving assembly is used to drive the cleaning assembly to move within the fixed frame. The cleaning assembly is provided with multiple cleaning nozzles for blowing air to clean the workpiece on the fixed fixture.

[0010] A further improvement to the above solution is that the cleaning connection assembly includes a vertical panel and a horizontal panel. The vertical panel and one end of the horizontal panel are connected to form an L-shaped bracket. One side of the vertical panel is connected to the moving end of the cleaning lifting module, and the other side is used to install the cleaning drive assembly. The horizontal panel is used to connect the fixed frame.

[0011] A further improvement to the above solution is that the cleaning drive assembly includes a connecting block, a drive cylinder, a sliding guide rail, and a drive connector. The drive cylinder is connected to the vertical panel through the connecting block. The sliding guide rail is disposed on the vertical panel. The drive connector is slidably mounted on the sliding guide rail and connected to the drive cylinder. The cleaning assembly is provided with a connecting piece that is connected to the drive connector.

[0012] A further improvement to the above solution is that the cleaning component includes a cleaning substrate, the cleaning substrate is provided with a plurality of cleaning grooves, and a plurality of cleaning nozzles are disposed on the cleaning grooves and can be adjusted in position along the cleaning grooves.

[0013] A further improvement to the above solution is that the cleaning nozzle includes a fixing component, a universal joint pipe, a nozzle connector, and a nozzle. The fixing component is installed on the cleaning groove and is used to connect the air supply pipe. The universal joint pipe is connected between the fixing component and the nozzle connector, and the nozzle is disposed on the nozzle connector.

[0014] A further improvement to the above solution is that the nozzle connector is an L-shaped connector and the end face of the nozzle is a spherical surface.

[0015] A further improvement to the above solution is that the flexible protective cover is made of transparent PET material and the thickness of the flexible protective cover is 1-3 mm.

[0016] A further improvement to the above solution is that the drilling and tapping mechanism includes a machining lifting module, a machining drive module, an adjusting frame, a universal joint assembly, and a clamping sleeve. The machining lifting module is mounted on the frame, the machining drive module is mounted on the machining lifting module, the adjusting frame is mounted on the fixed end of the machining drive module, the universal joint assembly is connected to the output end of the machining drive module, and the clamping sleeve is mounted on the universal joint assembly.

[0017] A further improvement to the above solution is that the universal joint assembly includes two universal couplings and an intermediate connecting shaft connecting the two universal couplings, and the two universal couplings are respectively connected to the output end of the machining drive module and the clamping sleeve.

[0018] The beneficial effects of this invention are:

[0019] Compared with the prior art, the present invention arranges multiple sets of fixed fixtures continuously on the turntable mechanism and sets multiple sets of drilling and tapping mechanisms and end cleaning mechanisms at the corresponding workstations, so that the workpiece can be drilled, tapped and cleaned sequentially on the same equipment, reducing the transfer of workpieces between different equipment and improving production continuity and cycle efficiency.

[0020] The cleaning mechanism is set up with the last set of fixed fixtures so that the workpiece can be directly cleaned by air blowing after drilling and / or tapping. This helps to remove residual debris, dust or cutting residue on the surface of the workpiece and near the holes in a timely manner, reducing the possibility of debris adhering to and entering subsequent processes.

[0021] By setting a fixed frame and a flexible protective cover around the perimeter of the cleaning mechanism, the flexible protective cover can cover the outside of the fixed fixture during cleaning, forming an outer barrier against the debris generated by the air blowing, preventing the debris from being blown directly to the outside of the equipment by the high-speed airflow, thereby reducing environmental pollution and reducing the possibility of debris falling into other workstations.

[0022] The cleaning assembly is equipped with multiple cleaning nozzles, which are adjustable via cleaning grooves. Combined with universal joint pipes and L-shaped connectors, the spray direction can be adjusted, thus enabling corresponding arrangements for different workpiece structures, hole distributions, or corner positions, improving the cleaning coverage and targeting.

[0023] The cleaning drive assembly adopts a structure that combines a drive cylinder and a sliding guide rail, which can drive the cleaning assembly to move stably within a fixed frame. This allows the cleaning nozzle to approach the workpiece to be cleaned more systematically, reducing spray position deviation and improving the consistency of the cleaning process.

[0024] The drilling and tapping mechanism is equipped with a universal joint assembly. Two universal couplings and an intermediate connecting shaft connect the output end of the machining drive module and the clamping sleeve. This helps to form a certain transmission compensation capability between the clamping sleeve and the drive end, thereby improving the adaptability of the clamping sleeve to the machining tool.

[0025] The drilling and tapping mechanism and the cleaning mechanism are arranged together on the same frame and around the turntable mechanism, forming a multi-station integrated structure. This saves equipment layout space and facilitates centralized control and unified maintenance, making it suitable for automated batch processing scenarios. Attached Figure Description

Detailed Implementation

[0028] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0029] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] like Figures 1-7 As shown, this invention provides a rotary drilling, tapping, and cleaning device, suitable for automated processing scenarios involving hardware parts, die-cast parts, mechanical structural parts, and other workpieces that require sequential drilling, tapping, and post-processing cleaning. This device arranges multiple processing stations and an end-of-line cleaning station around a rotary mechanism 2, allowing the workpiece to sequentially complete different processes on a fixed fixture 3 along with the rotary mechanism 2, thus forming a relatively continuous automated processing path.

[0032] See Figures 1-3 As shown, the rotary drilling, tapping, and cleaning equipment of the present invention includes a frame 1, a rotary mechanism 2, a fixing fixture 3, multiple sets of drilling and tapping mechanisms 4, and a cleaning mechanism 5. The frame 1 serves as the supporting foundation for the entire machine and is used to install the rotary mechanism 2, the multiple sets of drilling and tapping mechanisms 4, and the cleaning mechanism 5. The frame 1 can be in the form of a welded steel frame, a plate frame, or a profile combination frame, as long as it can meet the requirements for the operational stability of the rotary mechanism 2 and the installation strength of the actuators at each workstation.

[0033] The turntable mechanism 2 is mounted on the frame 1 and is mainly used to drive multiple sets of fixed fixtures 3 to sequentially switch between different workstations. The turntable mechanism 2 can adopt conventional structures such as a disc-type turntable, an intermittent indexing turntable, or a servo indexing turntable. For this invention, the key is that the fixed fixtures 3 can be continuously arranged along the rotation direction of the turntable mechanism 2 and sequentially pass through the corresponding drilling, tapping, and cleaning workstations under the drive of the turntable mechanism 2.

[0034] Multiple sets of fixed fixtures 3 are provided, and these sets of fixed fixtures 3 are continuously arranged along the rotation direction of the turntable mechanism 2. The fixed fixtures 3 are used to position and clamp the workpiece, ensuring that the workpiece maintains a stable position during rotation. Since this invention is mainly used for multi-station continuous processing, the multiple fixed fixtures 3 are preferably evenly distributed around the circumference of the turntable mechanism 2. Of course, the specific number of fixed fixtures 3 can be configured according to the number of stations and equipment cycle time requirements, and does not constitute a limitation of this invention.

[0035] Multiple drilling and tapping mechanisms 4 are configured corresponding to multiple sets of fixed fixtures 3, and are used to drill and / or tap the workpieces on the fixed fixtures 3. That is, along the rotation direction of the turntable mechanism 2, one or more drilling stations, one or more tapping stations, or a combination of drilling and tapping stations can be set sequentially. In this way, when a fixed fixture 3 carries a workpiece to the corresponding station, the drilling and tapping mechanism 4 at that station can perform the corresponding processing on the workpiece.

[0036] The cleaning mechanism 5 is positioned corresponding to the last set of fixing fixtures 3, and is used to clean the workpiece after drilling and / or tapping. The "last set of fixing fixtures 3" refers to the final station after the machining station and before the unloading station; it can also be understood as the final processing station for the workpiece before it leaves the machine's processing flow. By positioning the cleaning mechanism 5 at this location, the workpiece can be directly cleaned with air while still in its fixed state without requiring additional transfer after machining.

[0037] A key feature of this invention is the integration of multiple workstations into a single device via a turntable mechanism 2. After the workpiece is clamped onto the fixed fixture 3 at the initial workstation, it can sequentially enter the drilling, tapping, and cleaning workstations via intermittent or continuous indexing by the turntable mechanism 2. This avoids frequent manual handling of the workpiece and reduces connection errors between different devices.

[0038] In traditional solutions, post-processing cleaning often requires a separate workstation or manual blowing, which not only affects production rhythm but also easily causes debris contamination. In this invention, however, the cleaning mechanism 5 is directly located at the final workstation. The workpiece remains in place on the fixed fixture 3, allowing for air-blowing cleaning, facilitating the timely removal of debris residue from orifices, threaded areas, flat surfaces, and corners. This improves the quality of subsequent products and reduces the probability of chips and dust spreading to downstream processes.

[0039] See Figure 4 As shown, the drilling and tapping mechanism 4 includes a machining lifting module 41, a machining drive module 42, an adjusting frame 43, a universal connection assembly 44, and a clamping sleeve 45.

[0040] The machining lifting module 41 is mounted on the frame 1 and is used to move the entire machining execution component toward or away from the workpiece on the fixed fixture 3. The machining lifting module 41 can take the form of a cylinder lifting structure, an electric slide, a lead screw lifting mechanism, or a guide rail slider lifting mechanism. Its function is to feed the cutting tool or tool head downwards during machining and to raise it away from the workpiece when idle.

[0041] The machining drive module 42 is mounted on the machining lifting module 41. The machining drive module 42 provides rotational power to drive the cutting tool to perform drilling or tapping operations. The machining drive module 42 can be a motor spindle, a tapping motor, a pneumatic spindle, or other rotary drive units suitable for drilling and tapping operations.

[0042] An adjusting frame 43 is disposed at the fixed end of the machining drive module 42. The adjusting frame 43 serves as a mounting and positioning structure for the machining drive module 42, and can be used to adjust the mounting position, height, or angle relationship of the machining drive module 42 relative to the fixed fixture 3 to adapt to the machining needs of different workpiece positions. For different types of workpieces or different machining hole arrangements, the adjusting frame 43 can assist in the pre-adjustment of the mechanism position.

[0043] Universal connector 44 is connected to the output end of machining drive module 42, and clamping sleeve 45 is disposed on universal connector 44. Clamping sleeve 45 is used to clamp drill bits, taps or other machining tools. By setting universal connector 44 between machining drive module 42 and clamping sleeve 45, the drive transmission process can have a certain degree of attitude adaptability.

[0044] Furthermore, the universal joint assembly 44 includes two universal couplings 441 and an intermediate connecting shaft 442 for connecting the two universal couplings 441. The two universal couplings 441 are respectively connected to the output end of the machining drive module 42 and the clamping sleeve 45. Compared with a single rigid direct connection, this structure can compensate for the coaxial deviation or installation error between the clamping sleeve 45 and the machining drive module 42 to a certain extent, making the rotational power transmission more adaptable. This structure is particularly suitable for batch-configured machining heads in multi-station equipment, and helps to improve the transmission adaptation problem caused by the accumulation of assembly tolerances.

[0045] When the workpiece reaches a certain drilling or tapping station, the corresponding machining lifting module 41 actuates, driving the machining drive module 42, universal joint assembly 44, and clamping sleeve 45 to move closer to the workpiece. The machining drive module 42 outputs rotational power, which is transmitted to the clamping sleeve 45 via the universal joint assembly 44. The clamping sleeve 45 drives the clamped drill bit or tap to drill or tap the workpiece. After machining is completed, the machining lifting module 41 rises and resets, waiting for the turntable mechanism 2 to transfer the workpiece to the next station.

[0046] See Figures 5-7 As shown, the cleaning mechanism 5 includes a cleaning lifting module 51, a cleaning connection component 52, a cleaning protection component 53, a cleaning component 54, and a cleaning drive component 55.

[0047] The cleaning lifting module 51 is mounted on the frame 1 and is mainly used to drive the overall up-and-down movement of the cleaning connection assembly 52. ​​Similar to the function of the processing lifting module 41, the cleaning lifting module 51 can take the form of a cylinder, electric slide, guide rail module, etc. Its function is to switch the cleaning protection assembly 53 and the cleaning assembly 54 between the standby position and the cleaning operation position.

[0048] The cleaning connection component 52 is located at the moving end of the cleaning lifting module 51 and serves as the supporting connection base for the cleaning protection component 53, the cleaning component 54, and the cleaning drive component 55. The cleaning connection component 52 is equivalent to an intermediate mounting bracket, which is connected to the cleaning lifting module 51 on one hand and extends outward to support the fixing frame 531 and the cleaning drive component 55 on the other hand.

[0049] The cleaning protection component 53 is connected to the cleaning connection component 52. The cleaning protection component 53 includes a fixed frame 531 and a flexible protective cover 532. One side of the fixed frame 531 is connected to the cleaning connection component 52, and the flexible protective cover 532 surrounds the outer periphery of the fixed frame 531. The fixed frame 531 provides a supporting shape for the flexible protective cover 532, allowing it to form an enclosing space when pressed down onto the periphery of the fixed fixture 3. The flexible protective cover 532 is preferably made of transparent PET material with a thickness of 1–3 mm. Using transparent PET material ensures a certain degree of flexibility while facilitating observation of the workpiece and nozzle position inside the protective cover.

[0050] The cleaning component 54 is located above the cleaning protection component 53. Here, "above" means that when the cleaning mechanism is in its working position, the cleaning component 54 is located in the upper region of the fixed frame 531 and can extend into the area enclosed by the fixed frame 531 towards the workpiece. The cleaning drive component 55 is mounted on the cleaning connection component 52 and is mainly used to drive the cleaning component 54 to move within the fixed frame 531, allowing the multiple cleaning nozzles 544 on the cleaning component 54 to move closer to the workpiece or be adjusted to a more suitable spraying position.

[0051] The cleaning connection assembly 52 includes a vertical panel 521 and a horizontal panel 522, with one end of the vertical panel 521 and the horizontal panel 522 connected to form an L-shaped bracket.

[0052] One side of the vertical panel 521 is connected to the moving end of the cleaning lifting module 51, and the other side is used to install the cleaning drive assembly 55; the horizontal panel 522 is used to connect the fixing frame 531. The advantages of this L-shaped bracket structure are: First, it can distinguish the load-bearing direction of vertical movement from the cantilever direction of the front enclosure structure, making the mechanism layout clear. Second, the vertical panel 521 is suitable as the mounting plane for the drive cylinder and the sliding guide rail, which is conducive to forming a stable drive and guide relationship. Third, the horizontal panel 522 can be used to suspend the fixed frame 531 above the fixed fixture 3, forming an enclosing space for the fixture, and it is not easy to interfere with the drive structure on the vertical panel 521.

[0053] The cleaning drive assembly 55 includes a connecting block 551, a drive cylinder 552, a sliding guide rail 553, and a drive connector 554.

[0054] The drive cylinder 552 is connected to the vertical panel 521 via a connecting block 551. A sliding guide rail 553 is mounted on the vertical panel 521. The drive connecting block is slidably mounted on the sliding guide rail 553 and connected to the drive cylinder 552. The cleaning component 54 is provided with a connecting piece 542 connected to the drive connector 554. Through this structure, when the drive cylinder 552 actuates, it can drive the drive connecting block to move stably along the sliding guide rail 553, and then drive the cleaning component 54 to move. The sliding guide rail 553 improves the linear stability of the cleaning component 54 during movement and reduces sway.

[0055] In practical use, after the cleaning lifting module 51 has completed its overall downward press and the flexible protective cover 532 has been placed over the outside of the fixed fixture 3, the drive cylinder 552 can further drive the cleaning component 54 to a position closer to the workpiece. After cleaning is completed, the drive cylinder 552 reverses its movement, causing the cleaning component 54 to retract, and then the cleaning lifting module 51 is raised and reset as a whole.

[0056] The cleaning component 54 includes a cleaning base plate 541, on which a plurality of cleaning grooves 543 are provided, and a plurality of cleaning nozzles 544 are disposed on the cleaning grooves 543 and can be adjusted in position along the cleaning grooves 543.

[0057] The cleaning base plate 541 serves as a nozzle mounting platform, allowing for the arrangement of multiple nozzle mounting positions according to different workpiece contours and cleaning locations. The cleaning groove 543 provides the ability to adjust the position of the nozzles along the groove direction, enabling different nozzles to be distributed in more suitable positions according to the actual structure of the workpiece. This adjustable structure is particularly advantageous for workpieces with multiple holes, multiple stepped surfaces, or complex edge structures.

[0058] The cleaning nozzle 544 includes a fixing member 5441, a universal joint pipe 5442, a nozzle connector 5443, and a nozzle 5444. The fixing member 5441 is mounted on the cleaning groove 543 and used to connect the air supply pipe; the universal joint pipe 5442 connects the fixing member 5441 and the nozzle connector 5443; the nozzle 5444 is disposed on the nozzle connector 5443. Through the universal joint pipe 5442, the direction of the nozzle 5444 can be flexibly adjusted, allowing the spray to be aimed at a specific area of ​​the workpiece. The nozzle connector 5443 is preferably an L-shaped connector to guide the spray to lateral, oblique, or locally recessed areas. The end face of the nozzle 5444 is preferably spherical, which helps reduce interference problems caused by sharp shapes and facilitates a smoother outer contour when the nozzle tip is close to the workpiece.

[0059] Multiple cleaning nozzles 544 can be arranged at different angles and positions to allow airflow to act on the upper surface of the workpiece, the periphery of the orifice, the thread inlet, and the corners of the workpiece. The air supply pipeline can be connected to the equipment's compressed air system to supply air to the nozzles during cleaning operations.

[0060] When the turntable mechanism 2 brings the workpiece that has been drilled and / or tapped to the final fixed fixture 3 position, the cleaning mechanism 5 begins to operate. First, the cleaning lifting module 51 moves downward, causing the cleaning connecting assembly 52 to move downward as a whole, which in turn causes the fixed frame 531, flexible protective cover 532, and cleaning assembly 54 to move towards the fixed fixture 3 simultaneously. As it moves downward, the flexible protective cover 532 gradually surrounds the outside of the fixed fixture 3, forming a local enclosed space.

[0061] Subsequently, the cleaning drive assembly 55 actuates, and the drive cylinder 552 drives the cleaning assembly 54 to move along the sliding guide rail 553, causing multiple cleaning nozzles 544 to move closer to the workpiece. At the same time, compressed air is delivered to the nozzles 5444 through the fixing member 5441, the universal joint pipe 5442, and the nozzle connector 5443. The nozzles 5444 spray airflow onto the workpiece to blow away debris from the workpiece surface and in the grooves.

[0062] Because the flexible protective cover 532 is positioned around the fixed fixture 3, most of the debris blown up during workpiece cleaning is confined to the vicinity of the fixed fixture 3 or the area surrounding the flexible protective cover 532, preventing it from directly scattering outside the equipment. This not only improves the working environment but also reduces debris accumulation at other workstations. After cleaning, the cleaning drive assembly 55 first drives the cleaning assembly 54 to retract, and then the cleaning lifting module 51 drives the entire mechanism to rise and reset, awaiting the next workpiece to enter the cleaning station.

[0063] This invention integrates drilling, tapping, and cleaning stations around a turntable mechanism 2, enabling continuous processing of workpieces on a fixed fixture 3. On one hand, the drilling and tapping mechanism 4 utilizes a processing lifting module 41, a processing drive module 42, and a universal connection assembly 44 to stably process the workpiece; on the other hand, the cleaning mechanism 5 promptly removes debris with air at the end of the processing. In particular, the structure combining a flexible protective cover 532 with multiple adjustable nozzles ensures that the cleaning process is both highly targeted and able to control the range of debris diffusion.

[0064] Therefore, this invention is suitable for drilling and tapping production lines that require high-speed, multi-station, and automated processing, and has good practicality and promotional value.

[0065] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
