[0020] The present invention provides a device for cleaning the internal threads of a bolt. Figure 1-3As shown, the device for cleaning the internal threads of bolts includes: a workbench 1 fixedly mounted with a gantry 2; a drain outlet 3, the drain outlet 3 being fixedly opened on the workbench 1 and arranged corresponding to the gantry 2; a support seat 4, the support seat 4 being fixedly mounted on the gantry 2, and the support seat 4 being arranged corresponding to the drain outlet 3; a brush 5, the brush 5 being fixedly mounted on the support seat 4; a mounting plate 6, the mounting plate 6 being fixedly mounted on the gantry 2; a movable opening 7, the movable opening 7 being opened on the mounting plate 6; a positioning plate 8, the positioning plate 8 being fixedly mounted in the movable opening 7; a lifting screw 9, the lifting screw 9 being rotatably mounted on the positioning plate 8; and a cleaning mechanism, the cleaning mechanism being arranged on the lifting screw 9 for cleaning impurities on the bolts.

[0021] In this embodiment, the workbench 1 and gantry 2 serve as the basic support structure. The workbench 1 firmly supports the entire cleaning apparatus, while the gantry 2 spans across it, providing a stable platform and mounting base for subsequent cleaning operations. This design enhances the overall stability and load-bearing capacity of the apparatus. A drain outlet 3 is fixedly located on the workbench 1, corresponding to the gantry 2, to facilitate the collection and discharge of impurities generated during the cleaning process, maintaining a clean working environment. A support base 4 is fixedly mounted on the gantry 2, corresponding to the drain outlet 3, to support and secure a brush 5, ensuring that the brush can accurately target the threaded portion of the bolt for cleaning. The brush 5, mounted on the support base 4, initially removes impurities from the bolt thread surface through physical friction, preparing for subsequent in-depth cleaning. A mounting plate 6 is fixed to the gantry 2, with a movable opening 7 provided for the lifting and positioning of the cleaning mechanism. This design allows the cleaning mechanism to be flexibly adjusted to accommodate the cleaning needs of bolts of varying sizes. A positioning plate 8 is secured within the movable opening 7, providing a stable mounting base for the lifting screw 9. The lifting screw 9 rotates up and down, driving the cleaning mechanism to precisely align with the bolt threads for deep cleaning. This mechanized lifting method improves cleaning accuracy and efficiency. The cleaning mechanism, mounted on the lifting screw 9, is the core of the entire device. It uses a meshing scraping method to remove impurities from the bolt threads. By working in conjunction with the lifting screw 9, the cleaning mechanism enables rapid and efficient cleaning of the bolt threads.

[0022] In a further preferred embodiment of the present invention, the cleaning mechanism includes a connecting block 10, two cleaning rods 11, two fixed blocks 12 and a bidirectional screw 13. The connecting block 10 is threadedly mounted on the lifting screw 9, and the two cleaning rods 11 are respectively slidably arranged on both sides of the connecting block 10. The two cleaning rods 11 are corresponding to the support seat 4 and the brush 5. The two fixed blocks 12 are respectively fixedly mounted on the two cleaning rods 11, and the bidirectional screw 13 is threadedly mounted on the two fixed blocks 12.

[0023] In this embodiment, a connecting block 10 serves as a bridge between the cleaning mechanism and the lifting screw 9. The connecting block 10 is threadedly mounted on the lifting screw 9 and can move up and down as the lifting screw rotates. This design allows the cleaning mechanism to precisely locate the threaded portion of the bolt, providing a foundation for subsequent cleaning operations. Two cleaning rods 11 are slidably mounted on either side of the connecting block 10, corresponding to the support base 4 and the brush 5. The sliding design of the cleaning rods 11 allows them to be adjusted according to the depth and width of the bolt threads, ensuring a close fit on the threaded surface, thereby more effectively removing impurities. A fixed block 12 is fixedly mounted on the cleaning rods 11, providing a mounting base for the bidirectional screw 13. The fixed position of the fixed block 12 ensures that the bidirectional screw 13 can stably act on the cleaning rods 11 during adjustment, enabling precise control of the spacing between the cleaning rods. The bidirectional screw 13 is threadedly mounted on the two fixed blocks 12. By rotating the bidirectional screws, the spacing between the two cleaning rods 11 can be simultaneously adjusted. This design allows the cleaning mechanism to adapt to the thread widths of bolts of different specifications, improving the versatility and flexibility of the device. At the same time, by adjusting the spacing between the cleaning rods, it can be ensured that the cleaning rods can fit closely to the bolt threads, thereby improving the cleaning effect.

[0024] In a further preferred embodiment of the present invention, a slide groove 14 is provided on the workbench 1, and the slide groove 14 is arranged corresponding to the gantry 2. A slider 15 is slidably installed in the slide groove 14, and a support block 16 is fixedly installed on the slider 15. A positioning mechanism is provided on the support block 16 for fixing the bolts to be cleaned, and the positioning mechanism is arranged corresponding to the support seat 4.

[0025] In this embodiment, a chute 14 is provided on the workbench 1, corresponding to the gantry 2. The chute 14 provides a sliding track for the slider 15, allowing the support block 16 and its bolts to move along the chute. This design increases the flexibility of the device and facilitates moving the bolts to the optimal cleaning position. The slider 15 slides within the chute 14, serving as a connecting component between the support block 16 and the workbench 1. The sliding performance of the slider 15 ensures smooth and stable movement of the support block 16, improving the accuracy of bolt positioning. The support block 16 is fixedly mounted on the slider 15 to carry and support the bolts to be cleaned. The design of the support block 16 should take into account the shape and size of the bolts to ensure that the bolts are firmly positioned on it to prevent them from shaking or falling off during the cleaning process. A positioning mechanism is provided on the support block 16 to secure the bolts to be cleaned. The specific form of the positioning mechanism can be designed according to the shape and size of the bolts. The positioning mechanism securely fixes the bolts to the support block 16, ensuring that the bolts do not shift or fall off due to external forces during the cleaning process, thereby improving cleaning efficiency and safety.

[0026] In a further preferred embodiment of the present invention, the positioning mechanism includes a fixed shaft 17, a socket 18 and a rotating motor 19, the fixed shaft 17 is rotatably mounted on the support block 16, the socket 18 is nested on the fixed shaft 17, the rotating motor 19 is fixedly mounted on the support block 16, and the output shaft of the rotating motor 19 is fixedly connected to the fixed shaft 17.

[0027] In this embodiment, the fixed shaft 17 is rotatably mounted on the support block 16 and serves as the rotation center of the holder 18. The design of the fixed shaft 17 should ensure that the holder 18 can rotate stably around it, thereby achieving the clamping and release of the bolt. The holder 18 is nested on the fixed shaft 17 and is used to directly clamp the bolt. The shape and size of the holder 18 should be designed according to the shape and size of the bolt to ensure that it can fit tightly with the bolt and provide sufficient clamping force. The rotating motor 19 is fixedly mounted on the support block 16, and its output shaft is fixedly connected to the fixed shaft 17. The rotating motor 19 serves as a power source and drives the opening and closing of the holder 18 by rotating the fixed shaft 17. This design realizes the automation of bolt clamping, improves work efficiency and reduces the difficulty of manual operation. When the bolt needs to be fixed on the support block 16 for cleaning, the rotating motor 19 starts and drives the fixed shaft 17 to rotate, thereby driving the thread of the bolt to fully contact with the cleaning rod 11.

[0028] In a further preferred embodiment of the present invention, an adjusting screw 20 is rotatably installed in the slide groove 14, and the adjusting screw 20 extends outside the workbench 1. A rotating motor 21 is fixedly installed on the workbench 1, and the output shaft of the rotating motor 21 is fixedly connected to the adjusting screw 20.

[0029] In this embodiment, an adjustment screw 20 is rotatably mounted within the chute 14 and extends outside the workbench 1. The adjustment screw 20 serves as a transmission component, rotating to push the slider 15 within the chute 14. This design makes adjusting the bolt position simple and precise, eliminating the need for manual movement of the slider. A rotary motor 21 is fixedly mounted on the workbench 1, its output shaft fixedly connected to the adjustment screw 20. The rotary motor 21 serves as the power source, driving the slider 15 by rotating the adjustment screw 20. This automated adjustment method improves work efficiency and reduces the complexity of manual operation. To adjust the bolt position within the chute 14, simply start the rotary motor 21, which rotates the adjustment screw 20. Due to the threaded fit between the adjustment screw 20 and the slider 15, the rotating adjustment screw pushes the slider 15 along the chute 14, thereby moving the support block 16 and the bolt to the desired position. This adjustment method is not only fast and accurate, but also ensures the stability of the bolt during movement.

[0030] In a further preferred embodiment of the present invention, a fan 22 is fixedly installed on the gantry 2, an exhaust pipe 23 is fixedly installed on the exhaust end of the fan 22, a nozzle is fixedly installed on the exhaust pipe 23, and the nozzle is correspondingly arranged with the support seat 4 for cleaning impurities on the bolts.

[0031] In this embodiment, a fan 22 is fixedly mounted on the gantry 2 and serves as an airflow generator. The fan 22 rotates to generate a powerful airflow, providing power for subsequent impurity removal. An exhaust pipe 23 is fixedly mounted on the exhaust end of the fan 22 to direct the airflow generated by the fan in a specific direction. The design of the exhaust pipe 23 should ensure smooth airflow and precise targeting of the area to be cleaned. A nozzle is fixedly mounted on the exhaust pipe 23 and serves as the airflow outlet. The shape and size of the nozzle should take into account the airflow's diffusion and cleaning effects to ensure efficient removal of impurities from the bolts. The nozzle's alignment with the support base 4 means that during the cleaning process, the nozzle can be directly aimed at the bolts and their surrounding area for precise impurity removal. During the bolt cleaning process, the cleaning mechanism performs a preliminary cleansing of the bolts. Subsequently, the fan 22 is activated, generating a powerful airflow that is directed through the exhaust pipe 23 and the nozzle toward the bolts and their surrounding area. The airflow from the nozzle creates a powerful impact force, blowing any remaining impurities off the bolt surface, thereby achieving thorough impurity removal. This cleaning method is not only fast and effective, but also prevents impurities from reattaching to the bolts during the cleaning process, thereby improving the cleaning effect.

[0032] In a further preferred embodiment of the present invention, a movable groove 24 is opened in the connecting block 10, and the movable groove 24 is arranged corresponding to the cleaning rod 11. A limit block 25 is fixedly installed on the cleaning rod 11, and the limit block 25 is slidably connected to the movable groove 24.

[0033] In the present embodiment, the movable groove 24 is provided in the connecting block 10 and is arranged corresponding to the cleaning rod 11. The movable groove 24 provides space for the sliding of the cleaning rod 11 and ensures its stability and directionality during the sliding process. The shape and size design of the movable groove 24 should take into account the cross-sectional shape and sliding range of the cleaning rod 11 to ensure that the two can fit closely. The limit block 25 serves as a connecting component between the cleaning rod 11 and the movable groove 24, which not only limits the sliding range of the cleaning rod 11, but also ensures its stability during the sliding process. The shape and size of the limit block 25 should match the movable groove 24 to avoid generating excessive gaps or friction during the sliding process. When the cleaning mechanism is working, as the bidirectional screw 13 rotates, the cleaning rod 11 will slide on both sides of the connecting block 10 to adapt to the width of different bolt threads. At this time, the limit block 25 slides in the movable groove 24, ensuring that the sliding direction of the cleaning rod 11 is correct and stable. At the same time, the stopper 25 also limits the sliding range of the cleaning rod 11, preventing it from disengaging from the connecting block 10 or damaging other components due to excessive sliding. This improves the stability and reliability of the cleaning rod 11's sliding within the connecting block 10. This design not only enables the cleaning mechanism to adapt to a wider variety of bolt cleaning needs, but also reduces the failure rate caused by poor sliding or disconnection. Furthermore, stable sliding ensures that the cleaning rod 11 maintains a close fit with the bolt threads during the cleaning process, improving cleaning effectiveness.

[0034] In summary, compared with related technologies, the cleaning mechanism adopts an engaging scraping method, combined with the precise control of the lifting screw, which can penetrate deep into the bolt thread, effectively scrape off impurities, and achieve efficient cleaning. Through the design of the positioning mechanism and the adjusting screw, the device can accurately locate the bolt and adjust its position, ensuring that the cleaning mechanism can accurately align with the bolt thread, thereby improving the accuracy of cleaning. By integrating automatic equipment such as rotating motors and rotary motors, the device realizes the automation of operations such as bolt fixing, position adjustment, and cleaning, reducing the difficulty and intensity of manual operation. The cleaning rod in the cleaning mechanism adopts a sliding design, combined with the adjustment function of the bidirectional screw, which can flexibly adapt to the thread width of bolts of different specifications, thereby improving the versatility and flexibility of the device. The impurities are cleaned by the airflow generated by the fan, which avoids the waste of water resources and environmental pollution problems in traditional high-pressure water gun cleaning methods, and is more environmentally friendly and energy-saving.
