[0002] A tapping machine is a mechanical device used to process threads. It is applied in the field of machinery manufacturing. It forms precise threads on the surface of a workpiece through rotary cutting. It is characterized by convenient operation and high efficiency. It is suitable for machining mechanical parts and producing hardware tools. With the increasing demand for industrial automation, traditional single-station equipment can no longer meet the requirements of mass production. Fully automatic multi-station tapping machines integrate multi-axis synchronous operation functions and are equipped with a control system to realize a continuous feeding, processing and inspection integrated process, which greatly improves production efficiency and product consistency, and has become an important part of modern manufacturing.

[0003] A search revealed Chinese Patent Publication No. CN104708323B, which discloses a fully automatic tapping machine with a variable angle cross shaft body. The machine includes a feeding device, a conveying device, a loading device, a drilling device, and a unloading device. The feeding device, conveying device, and loading device are mounted on a processing platform. The drilling device and unloading device are located to one side of the loading device, and the unloading device is located below the processing platform. This invention achieves automatic feeding, loading, drilling, tapping, and unloading through the integrated design of the feeding device, conveying device, loading device, drilling device, and unloading device. Furthermore, the drilling device has multiple fixed stations, enabling continuous processing and significantly improving production efficiency. However, in actual use, the above-mentioned device generates a large amount of debris during the tapping process, which cannot be effectively cleaned. This debris accumulates on the workbench and the ground, affecting the cleanliness of the working environment and potentially mixing into the workpiece or transmission components, causing equipment malfunctions. Therefore, a fully automatic multi-station tapping machine is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fully automatic multi-station tapping machine, which aims to improve the problem that the tapping process generates a large amount of debris that cannot be effectively cleaned. The debris accumulates on the workbench and the ground, which not only affects the cleanliness of the working environment, but also mixes into the workpiece or transmission components, causing equipment failure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fully automatic multi-station tapping machine, including a frame, with multiple guide grooves and multiple guide holes on the top of the outer wall of the frame, a fixed frame fixedly connected to the top of the outer wall of the frame, a connecting rod fixedly connected to the right side of the outer wall of the fixed frame, a sprayer fixedly connected to the right end of the outer wall of the connecting rod, and multiple water storage bottles fixedly connected to the outer wall of the frame, each of the multiple water storage bottles having two first guide pipes connected to its outer wall. The top of the outer wall of the machine is connected to a second guide pipe, the bottom of the outer wall of the second guide pipe is connected to a bucket lid, the top of the outer wall of the bucket lid is fixedly connected to a filter bucket, the inner wall of the filter bucket is fixedly connected to a filter plate, the top of the outer wall of the bucket lid is connected to a water suction pipe, the bottom of the water suction pipe is connected to a water pump, the top of the outer wall of the water pump is connected to a return pipe, the top of the return pipe is connected to a fixed frame, the top of the outer wall of the machine frame is provided with a tapping assembly, the outer wall of the machine frame is provided with a rotating assembly, and the front side of the outer wall of the machine frame is provided with a transmission mechanism.

[0006] The above technical solution utilizes a box-frame structure as the core load-bearing unit. Thick-walled steel plates are welded to form a high-strength support system, providing a precise assembly benchmark for the cutting mechanism and transmission components. This ensures dynamic rigidity meets standards during high-speed tapping operations. A guide channel is precisely milled on the top surface, featuring a V-shaped cross-section and a specific angle to guide the cutting fluid mixed with metal chips along a pre-defined path into the recovery station. A guide hole connects to the end of the guide channel, with a gradually changing aperture design optimizing fluid dynamics and achieving zero-residue discharge of waste liquid. A fixed frame is vertically welded to the right side of the top of the frame, serving as the base for the spray system. A connecting rod extends from the right side, rigidly connected to the sprayer via an adjustable flange. The sprayer is equipped with wide-angle fan-shaped nozzles, using high-pressure water to cover the cutting area, effectively removing aluminum chips and iron powder generated during thread cutting. Simultaneously, it cools the tool and lubricates the machined surface. This structural design avoids tool wear caused by heat conduction during cutting and, through... To ensure the precision of thread forming during continuous cleaning, the water storage bottles arrayed on the side wall of the frame are made of transparent and corrosion-resistant material. A siphon effect is formed through the first dual-channel guide pipe, continuously guiding the waste liquid collected in the guide channel into the temporary storage container. The second guide pipe connects the water storage bottle and the filter bucket at a certain angle, using gravitational potential energy to promote the initial sedimentation of the waste liquid. The bucket lid is equipped with a quick-release sealing ring and a safety locking mechanism, which allows for quick opening of the lid for filter media maintenance while maintaining the airtightness of the filter chamber. The filter plate uses a multi-layer stainless steel sintered filter screen, which intercepts particles larger than microns through the gradient filtration principle. Combined with the self-cleaning scraper mechanism, a dynamic purification mechanism is formed to ensure that the cleanliness of the coolant meets the standards for recycling. The suction pipe is connected to the water pump inlet through a flange, and the negative pressure generated by the centrifugal impeller pumps the filtered liquid into the return pipe. Finally, it is redistributed to the sprayer through the internal pipeline of the fixed frame, forming a closed-loop liquid regeneration system. The water pump, as the core of the fluid drive, ensures the continuous and efficient operation of the cutting fluid in the flushing, filtering and return process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

A connecting rod 6 is fixedly connected to the right side of the outer wall of the fixing frame 5, which is used to connect the spray system and the fixing frame 5. A sprayer 7 is fixedly connected to the right end of the outer wall of rod 6. The sprayer 7 in the tapping machine cleaning system uses high-pressure spray of coolant or cleaning agent to flush away metal shavings and oil generated during processing, preventing shavings accumulation from affecting equipment operation and thread accuracy. It also assists in cooling and lubricating the cutting tools to extend their service life, ensuring a clean and efficient processing environment. The sprayer 7 in the tapping machine cleaning system uses high-pressure spray of clean water to flush away metal shavings and oil generated during processing, preventing shavings accumulation from affecting equipment operation and thread accuracy. It also assists in cooling and lubricating the cutting tools to extend their service life, ensuring a clean and efficient processing environment. Multiple water storage bottles 8 are fixedly connected to the outer wall of the frame 1 for temporary storage of wastewater. The outer walls of the multiple water storage bottles 8 are connected to two first guide pipes 9. 9 is used to guide the wastewater to the water storage bottle 8. The top of the outer wall of the water storage bottle 8 is connected to a second guide pipe 10, and the bottom of the outer wall of the second guide pipe 10 is connected to a bucket lid 15. The bucket lid 15 seals the filter chamber through a sealing structure, preventing external impurities from entering, while facilitating quick opening for cleaning or replacement of the internal filter media, ensuring the purity of the filter media and the long-term operational stability of the system. A filter bucket 11 is fixedly connected to the top of the outer wall of the bucket lid 15. The second guide pipe 10 guides the wastewater from the water storage bottle 8 to the filter bucket 11. A filter plate 16 is fixedly connected to the inner wall of the filter bucket 11. It physically intercepts metal shavings and impurities generated during processing, ensuring that the coolant or cleaning agent remains clean during circulation, preventing contaminants from flowing back to the processing area, thereby extending equipment life and reducing [the risk of contamination]. To mitigate the risk of pipe blockage, a suction pipe 12 is connected to the top of the outer wall of the bucket lid 15. The bottom of the suction pipe 12 is connected to a water pump 13. The suction pipe 12 draws filtered water into the water pump 13, which pressurizes and delivers coolant or cleaning agent, driving the liquid to flow continuously in the spray filtration and recovery process. This ensures efficient and coordinated debris flushing and media purification. A return pipe 14 is connected to the top of the outer wall of the water pump 13, and a mounting bracket 5 is connected to the top of the return pipe 14. A tapping assembly is installed on the top of the outer wall of the frame 1. The tapping assembly includes a base 17, which ensures the stability of the tapping assembly during operation.

The bottom of the outer wall of the fixed base 20 is fixedly connected to the top of the outer wall of the frame 1. A turntable 19 is fixedly connected to the top of the outer wall of the fixed base 20. This turntable 19 carries and automatically positions the workpiece through multi-station rotation, enabling continuous feeding, tapping, inspection, and unloading in a production line. A transmission mechanism 2 is provided on the front side of the outer wall of the frame 1.

[0041] Specifically, the frame 1, as the core support structure of the equipment, is cast from high-strength materials, providing a stable base and rigid frame for the entire machine. This ensures that each functional unit is in a precise relative position during cutting operations, withstands machining vibrations and load impacts, and maintains the overall dynamic balance of the equipment. Multiple guide channels 3 are opened on the top of its outer wall according to fluid mechanics principles. Through trapezoidal cross-sections and inclined angles, directional flow channels are formed to quickly guide the mixed waste liquid of cutting oil and metal chips to the filtration and recovery unit. The ends of the guide channels 3 are connected to guide holes 4, which use a gradually changing aperture to optimize drainage efficiency and avoid secondary pollution caused by waste liquid residue. The fixed frame 5 is vertically fixed to the top of the machine frame 1 by welding, serving as the installation reference surface for the spray system. A connecting rod 6 extends from its right side and is rigidly connected to the sprayer 7 via an adjustable flange interface. The sprayer 7 is equipped with multi-angle high-pressure nozzles, outputting clean coolant at a certain pressure to form a fan-shaped water curtain covering the contact surface between the tool and the workpiece. This effectively removes aluminum chips and iron powder from the cutting area, simultaneously achieving tool cooling and lubrication of the machined surface. This structural design avoids heat buildup during cutting that could lead to tool annealing, and ensures thread profile accuracy through real-time cleaning. The water storage bottles 8, arranged in an array on the side of the machine frame 1, are made of transparent polycarbonate material. A liquid level gauge is placed, and a siphon effect is formed through the dual-path first guide pipe 9 to continuously guide the waste liquid collected in the guide trough 3 into the temporary storage space. The second guide pipe 10 connects the water storage bottle 8 and the filter bucket 11 at a certain angle, using gravitational potential energy to achieve initial sedimentation and stratification of the waste liquid. The bucket lid 15 adopts a quick-release silicone sealing ring and stainless steel buckle design, which ensures the airtightness of the filter chamber while allowing a single person to complete filter media maintenance within five minutes. The filter plate 16 is made of sintered stainless steel and intercepts particulate matter step by step through a five-layer gradient filter structure. Combined with a self-cleaning scraper mechanism, a dynamic filtration mechanism is formed. (The text abruptly ends here, likely due to an incomplete sentence or missing information.) 12 connects to the inlet of water pump 13 via flange, and uses a centrifugal impeller to generate negative pressure, pumping the filtered liquid to return pipe 14, and finally redistributing it to sprayer 7 through the internal pipeline of fixed frame 5, forming a closed-loop liquid circulation system. The tapping assembly on the top of frame 1 is equipped with servo drive base 17, and tapping drill 18 integrates tool holder interface and torque monitoring module, supporting quick replacement of multiple specifications of taps. Turntable 19 is driven by motor and equipped with a six-station vacuum suction cup clamp, completing the automatic flow of workpieces every minute, and linking with transmission mechanism 2 to form a continuous processing cycle. The whole machine is controlled by PLC to coordinate the operation of each subsystem.

[0042] Reference Figure 1 , Figure 4 and Figure 5 The transmission mechanism 2 includes a fixed block 201, which is used to improve the stability of the transmission mechanism 2. The rear side of the outer wall of the fixed block 201 is fixedly connected to the front side of the outer wall of the frame 1. A sliding plate 202 is slidably connected to the front side of the outer wall of the fixed block 201. A cylinder 203 is fixedly connected to the top of the outer wall of the sliding plate 202, which is used to provide an upward force to the sliding plate 202. The sliding plate 202 is used to connect the main transmission components and the cylinder 203. A pneumatic rod 204 is fixedly connected to the rear side of the outer wall of the sliding plate 202. A push plate 205 is fixedly connected to the rear side of the outer wall of the pneumatic rod 204, which is the core component for pushing the workpiece. The pneumatic rod 204 is used to push the push plate 205 forward, thereby transporting the workpiece to the designated position.

[0043] Specifically, the transmission mechanism 2 serves as the core unit for power transmission, and the integrated fixed block 201 serves as the basic support module. The fixed block 201 is rigidly connected to the front wall of the frame 1 through the rear side wall to form a stable force transmission path. The front wall of this module is equipped with a sliding plate 202 that can slide along the axial direction. The top surface of the sliding plate 202 is rigidly equipped with a cylinder 203. The cylinder 203 serves as a vertical driving force source, providing a continuous lifting force to the sliding plate 202. The rear wall of the sliding plate 202 is fixedly equipped with a pneumatic rod 204. The end of the pneumatic rod 204 is rigidly connected to a push plate 205. The push plate 205 serves as the workpiece contact interface. Through the linear telescopic movement of the pneumatic rod 204, the driving force is converted into the translational kinetic energy of the workpiece, realizing the precise transfer of processed materials between workstations.

[0044] Reference Figure 1 , Figure 2 and Figure 4 Foot pads 21 are fixedly connected to the four corners of the bottom of the outer wall of the frame 1. The surface of the foot pads 21 is rounded. Through elastic buffering and friction adjustment, they can stably support the overall frame of the equipment, absorb the vibration of operation and prevent displacement and slippage. A bracket 22 is fixedly connected to the front of the outer wall of the frame 1. A controller 23 is fixedly connected to the top of the outer wall of the bracket 22. The controller 23 is used to control the start and stop of the device. The bracket 22 is used to support the controller 23. Multiple indicator lights 24 are fixedly connected to the front of the outer wall of the frame 1. They can intuitively display the abnormal alarm of the equipment operation status and the workstation operation readiness status through color or flashing mode, and help the operator quickly grasp the machine operation status. The multiple indicator lights 24 are all arranged at equal intervals. A power cord 25 is fixedly connected to the rear of the outer wall of the frame 1. It can stably transmit external power to the equipment drive system through the cooperation of conductive core and insulating outer layer. A plug 26 is fixedly connected to the rear of the outer wall of the power cord 25. It realizes the physical connection between the equipment and the power supply with a standardized interface structure to ensure stable current conduction.

[0045] Specifically, the frame 1 serves as the basic load-bearing structure of the equipment. Its four corners are rigidly fitted with foot pads 21. These foot pads 21 feature rounded edges and are made of high-damping rubber material. Through elastic deformation, they absorb the multi-directional vibration energy generated during equipment operation. Combined with the anti-slip texture on the bottom, they enhance the adhesion of the contact surface, ensuring the positioning stability of the entire machine under high-speed processing conditions. The front wall of the frame 1 integrates a bracket 22 as a control unit mounting platform. A controller 23 is precisely mounted on the top surface of the bracket 22. This controller 23 integrates a human-machine interface and a logic control module. Through a bus communication protocol, it coordinates the timing of actions of each actuator, achieving intelligent management of the processing flow. Equivalently spaced rows of... Multiple indicator lights 24 are installed, using three-color LED light sources with differentiated flashing frequencies to provide real-time feedback on the three basic states of the equipment: standby operation, alarm, etc., and to simultaneously indicate the loading and unloading preparation status of each workstation, forming a visual monitoring system. The power cord 25 is fixedly laid on the rear wall of the frame 1. Its internal multi-strand tinned copper core conductor and double-layer flame-retardant insulation sheath ensure the safe and stable transmission of three-phase AC power. The end of the power cord 25 is crimped with an industrial-grade plug 26. The outer shell of the plug 26 is made of flame-retardant PC material, and the internal silver-plated pins and socket form a low-impedance path. The high protection level design effectively isolates the intrusion of dust and liquid, ensuring that the equipment can continuously obtain a clean power supply in a humid and oily environment.

[0046] Working principle: First, when the cleaning system is running, the sprayer 7 sprays cleaning liquid at a certain pressure into the processing area, forming a fan-shaped water flow to directionally flush the cutting surface, flushing the metal scrap and oil mixture into the guide channel 3. The guide channel 3 is designed with a certain inclination angle to guide the waste liquid to flow quickly, and enters the water storage bottle 8 through the guide hole 4 for temporary storage. The first guide pipe 9 of the double path transports the waste liquid to the filter bucket 11 by the siphon principle. The filter plate 16 uses a five-layer stainless steel filter screen to intercept particulate matter in a gradient. Solid-liquid separation is achieved through physical sieving. The purified liquid is pressurized by the water pump 13 through the water suction pipe 12 and reinjected into the sprayer 7 through the return pipe 14 to form a closed loop circulation. This system realizes real-time cleaning of cutting waste, effectively avoiding tool wear and processing accuracy reduction and pipeline blockage caused by debris deposition, and ensuring the stability of continuous equipment operation.

[0047] Furthermore, the transmission mechanism 2 drives the sliding plate 202 to perform vertical reciprocating motion through the bottom cylinder 203, precisely controlling the start and stop sequence of the transmission unit. The top surface of the sliding plate 202 is rigidly connected to the air rod 204, which drives the push plate 205 to push linearly through a preset motion cycle, conveying the workpiece to be processed along the guide rail to the tapping station. This design eliminates the motion interference and inertial impact problems of traditional sprocket and rack transmission. The push plate 205 adopts a composite structure of polyurethane buffer pad and guide pin, which not only ensures the repeatability of workpiece positioning, but also avoids scratches on the workpiece surface through flexible contact. The transmission system adopts a modular design, which facilitates maintenance and stroke parameter adjustment, and significantly improves the equipment uptime and production cycle stability.
