[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] Reference Figure 1~Figure 5 , which is the first embodiment of the present invention, proposes a multi-station tapping machine for tapping nut blanks, including: a feed port 110 is provided on a frame 1; a first rotating disk 2 is rotatably arranged on the frame 1; there are a plurality of tapping pieces 3, which are circumferentially spaced and arranged on the first rotating disk 2. When the first rotating disk 2 rotates, different tapping pieces 3 pass through and align with the feed port 110, and the tapping pieces 3 are used to accommodate and tap the nut blanks.

[0023] In this embodiment, the nut blank gradually enters the tapping machine from the feed port 110. When the first rotating disk 2 rotates the tapping piece 3 to the feed port 110, the nut blank is fed into the tapping piece 3 and rotates with the first rotating disk 2. During the rotation of the first rotating disk 2, the tapping piece 3 will tap the blank. The tapping process is a movement process, and it takes time to wait during the tapping process. The nut of this solution will enter the tapping piece 3, and another tapping piece 3 will continue to take over the nut to be tapped. The tapping process is carried out during the rotation of the first rotating disk 2. After one circle of rotation, the tapping piece 3 can continue to take over the next nut to be tapped, which improves the continuity of the tapping process. The efficiency of tapping is greatly improved. The frame 1 provides a stable support structure for the entire multi-station tapping machine, ensuring the stability and reliability of the equipment during operation. The rotation design of the first rotating disk 2 realizes the switching of the workstations, improving the continuity and efficiency of processing. Multiple tapping pieces 3 are arranged at intervals on the circumference, which increases the number of simultaneous processes and greatly improves the production efficiency of the tapping machine. Different tapping pieces 3 can pass through the feed port 110 in sequence and align, realizing the continuous operation of automatic feeding and tapping, reducing manual intervention and labor intensity. This tapping machine can tap multiple nut blanks at the same time, improving the utilization rate and production capacity of the equipment and reducing the production cost of the unit product.

[0024] As a further technical solution, the tapping part 3 includes: a plurality of limit sleeves 210, which are rotatably arranged on the first rotating disk 2, and the plurality of limit sleeves 210 are arranged at circumferential intervals. The limit sleeves 210 have a limit space 211, and the limit space 211 runs through the limit sleeves 210. After the first rotating disk 2 rotates, the limit space 211 is connected to or disconnected from the feed port 110, and the limit space 211 is used to accommodate the nut blank; the tap 220 is slidably arranged on the frame 1, and the tap 220 enters or leaves the limit space 211 after sliding, and the tap 220 is used to tap the nut blank.

[0025] In this embodiment, the provision of multiple limiting sleeves 210 significantly increases the number of nut blanks that can be processed simultaneously. In actual production, this means that more workpieces can be processed in the same time, thereby greatly improving the overall production efficiency. Moreover, this batch processing method can also reduce the interruption and waiting time in the production process, making the production process smoother and more continuous. The limiting sleeve 210 is rotatably arranged on the first rotating disk 2, so that during the rotation of the first rotating disk 2, each limiting sleeve 210 can be aligned or staggered with the feed port 110 extremely accurately. This not only ensures the accuracy and timeliness of the feed, but also makes the entire processing process proceed in an orderly manner, avoiding production confusion and delays caused by inaccurate station switching. The limiting space 211 is used to accommodate the nut blank, and its internal structure can position and limit the nut blank in all directions. During the tapping process, the nut blank can be firmly fixed in the limiting space 211, and there will be no shaking, displacement, etc., thereby effectively ensuring the accuracy and quality of the tapping. At the same time, this stable positioning also helps to reduce the scrap rate caused by the instability of the workpiece, and improves the consistency and reliability of the product. The tap 220 is slidably arranged on the frame 1, so that it can flexibly and accurately enter and leave the limited space 211. This sliding action responds quickly and can accurately perform the tapping operation according to the preset program or control signal. In addition, the sliding design makes it easier to control the force and depth of the tap 220 during tapping, so as to meet the tapping requirements of nut blanks of different specifications and requirements.

[0026] As a further technical solution, it also includes: the ring gear 120 is arranged on the frame 1; the gear 130 is arranged on the limiting sleeve 210, and the gear 130 is meshed with the ring gear 120.

[0027] In this embodiment, the use of the gear ring 120 and the gear 130 can provide additional rotational power for the limit sleeve 210 when the limit sleeve 210 rotates with the first rotating disk 2. This allows the nut blank to not only switch positions with the first rotating disk 2 during the tapping process, but also rotate itself, thereby achieving a more uniform and accurate tapping effect. Since the gear 130 and the gear ring 120 are always in meshing, the stability and continuity of the rotation of the limit sleeve 210 are ensured, and the speed and accuracy of the rotation will not be affected by changes in the rotation speed of the rotating disk or other external factors, which is conducive to improving the quality and consistency of tapping.

[0028] As a further technical solution, it also includes: a second rotating disk 310 is rotatably set on the frame 1, and the second rotating disk 310 rotates with the first rotating disk 2; there are several telescopic parts 4, which are circumferentially spaced and set on the second rotating disk 310, and the telescopic parts 4 have a telescopic end 410, and the tap 220 is set on the telescopic end 410.

[0029] In this embodiment, the second rotating disk 310 is arranged to rotate synchronously with the first rotating disk 2, ensuring that the movement of the telescopic member 4 and the tap 220 is coordinated with the station switching of the limiting sleeve 210 on the first rotating disk 2, thereby improving the synchronization and continuity of the entire tapping process. The multiple telescopic members 4 arranged at circumferential intervals can simultaneously drive the multiple taps 220 to perform telescopic movement, further improving the efficiency of tapping and realizing multi-station synchronous tapping operation. The telescopic function of the telescopic member 4 enables the tap 220 to accurately control the depth and speed of entering and leaving the limiting space 211, thereby adapting to the tapping requirements of nut blanks of different specifications and ensuring the stability and consistency of the tapping quality. The tap 220 is installed on the telescopic end 410 of the telescopic member 4. This structural design enables the position and posture of the tap 220 to be adjusted more flexibly, thereby improving the precision and accuracy of tapping.

[0030] As a further technical solution, the tap 220 has a guide rod 230 at one end away from the limiting sleeve 210, and the guide rod 230 is used to guide the nut that has been tapped to leave the tap 220, and also includes: a connecting seat 420 is arranged at the telescopic end 410 of the telescopic member 4; there are a number of connecting rods 430, which are arranged on the connecting seat 420, and a limiting space 211 is formed between the several connecting rods 430 and the connecting seat 420, and the guide rod 230 is located in the limiting space 211, and the limiting space 211 is used to prevent the guide rod 230 from falling.

[0031] In this embodiment, the guide rod 230 on the tap 220 can effectively guide the nut that has been tapped to leave the tap 220, ensuring that the processed nut can be discharged smoothly and avoid being retained on the tap 220, thereby improving the continuity and efficiency of production. The connecting seat 420 is arranged at the telescopic end 410 of the telescopic member 4, providing a stable installation foundation for the connecting rod 430 and the tap 220, ensuring the stability and reliability of the structure during the tapping process. The limiting space 211 formed between the connecting rods 430 and the connecting seat 420 can reliably accommodate the guide rod 230, prevent the guide rod 230 from accidentally falling during the working process, and avoid production interruption and equipment failure caused by the falling of the guide rod 230. The limiting space 211 ensures that the guide rod 230 is always in the correct position, so that it can continue to play the role of guiding the nut to be discharged, ensuring the smooth progress of the tapping operation.

[0032] As a further technical solution, it also includes: the first rotating disk 2 and the second rotating disk 310 of the rotating connecting rod 140 are both arranged on the rotating connecting rod 140; the rotating driving member 150 is arranged on the frame 1, and the rotating driving member 150 is used to drive the rotating connecting rod 140 to rotate.

[0033] In this embodiment, the rotating connecting rod 140 connects the first rotating disk 2 and the second rotating disk 310 together, realizing the synchronous rotation of the two, ensuring the coordinated cooperation of the tapping station and the telescopic action of the tap 220, and making the entire tapping process more precise and stable. The rotating driving member 150 drives the rotating connecting rod 140 to rotate, providing a unified and stable power source for the rotation of the first rotating disk 2 and the second rotating disk 310, reducing the problem of rotation incoordination that may be caused by different power inputs. This centralized driving method makes the structure of the equipment more compact, reduces the number of transmission components, reduces the probability of failure, and improves the reliability and maintenance convenience of the equipment. The rotating driving member 150 can adjust the rotation speed and rotation angle of the rotating connecting rod 140 through precise control, so as to flexibly adapt to different production needs and process requirements, and improve the production efficiency and adaptability of the equipment.

[0034] As a further technical solution, it also includes: the cooling coil 5 is arranged on the frame 1; there are a plurality of nozzles 510, which are arranged on the cooling coil 5 in an array at intervals, and the plurality of nozzles 510 are all facing the tap 220, and the nozzles 510 are used to spray coolant onto the tap 220.

[0035] In this embodiment, the cooling coil 5 is arranged on the frame 1, providing a stable channel for the delivery of the coolant, ensuring that the coolant can be continuously supplied to the parts that need cooling. The multiple nozzles 510 arranged at intervals in the array can be directed to the tap 220 in all directions, so that the coolant can be evenly sprayed on the tap 220, effectively covering all parts of the tap 220, and achieving a comprehensive and efficient cooling effect. Spraying coolant on the tap 220 can promptly take away a large amount of heat generated during the tapping process, reduce the temperature of the tap 220, reduce the wear and deformation of the tap 220 caused by high temperature, and extend the service life of the tap 220.

[0036] As a further technical solution, the frame 1 has a plurality of blanking holes 160 , and also includes: a collecting barrel 170 is arranged on the frame 1 , the collecting barrel 170 is connected with the blanking holes 160 , and the collecting barrel 170 is used to guide and collect the nuts that have been tapped.

[0037] In this embodiment, a plurality of drop holes 160 on the frame 1 provide a channel for the nuts that have been tapped to be quickly discharged, so as to avoid the accumulation of processed nuts at the workstation and affect the subsequent processing operations, thereby improving the continuity and efficiency of production. The collecting barrel 170 is connected to the drop holes 160, and can effectively guide the nuts that fall from the drop holes 160 to enter the collecting barrel 170 in an orderly manner, preventing the nuts from scattering, and ensuring the cleanliness and orderliness of the working area. The setting of the collecting barrel 170 facilitates the centralized collection of the nuts that have been tapped, facilitates the subsequent sorting, transportation and storage, reduces the workload of manual collection, and improves the overall efficiency of production.

[0038] As a further technical solution, the collecting barrel 170 has a guiding inclined surface 180 and a plurality of water outlet holes 190 located on the guiding inclined surface 180 .

[0039] In this embodiment, the guiding bevel 180 on the aggregate barrel 170 can make the nuts that fall into the aggregate barrel 170 slide to the bottom more smoothly, reduce the jamming and accumulation of the nuts in the aggregate barrel 170, and ensure the efficient collection process. The setting of the water outlet 190 can discharge the liquid in time when the nuts are cleaned or coolant enters the aggregate barrel 170, prevent the liquid from accumulating in the aggregate barrel 170, thereby avoiding the nuts being soaked in the liquid and corroded or affecting subsequent processing. The cooperation of the guiding bevel 180 and the water outlet 190 helps to keep the inside of the aggregate barrel 170 dry and clean, is conducive to the storage and subsequent processing of the nuts, and improves the quality and storage conditions of the product. The water outlet 190 is located on the guiding bevel 180, and the inclination of the bevel can be used to accelerate the discharge speed of the liquid, improve the drainage efficiency, and ensure the normal function of the aggregate barrel 170.

[0040] As a further technical solution, it also includes: a water storage tank 200 is arranged below the material collecting barrel 170, and the water storage tank 200 is used to collect water falling from the water outlet 190.

[0041] In this embodiment, the water storage tank 200 is arranged below the collecting barrel 170, which can accurately collect the water falling from the water outlet 190, avoid water overflow, and keep the working environment clean and dry. The centralized collection of the water falling from the water outlet 190 is conducive to the recycling or unified treatment of water resources, which meets the requirements of energy conservation and environmental protection. It prevents water from flowing directly to the ground and causing safety hazards such as slipping, thereby ensuring the work safety of operators. The existence of the water storage tank 200 can effectively monitor the flow and quality of water, making it easy to promptly discover possible problems, such as coolant leakage, so as to carry out maintenance and repairs in a timely manner.
