[0027] Example

[0028] like Figures 1-4 As shown, this utility model provides a technical solution: an inner ring cleaning device for nut processing, including a cleaning tank 1. Symmetrically distributed support blocks 2 are fixedly connected to both sides of the cleaning tank 1. Servo electric cylinders 3 are fixedly installed on the upper end of the support blocks 2. One end of the piston rods of both servo electric cylinders 3 is fixedly connected to a cover plate 4. The servo electric cylinders 3, as power drive components, have precise stroke control capabilities and can quickly and smoothly drive the cover plate 4 to lift and lower according to instructions. When the cleaning process needs to be started, the piston rod retracts, allowing the cover plate 4 to tightly fit against the upper end of the cleaning tank 1, effectively preventing water splashing during cleaning and maintaining a dry and clean working area. After cleaning, the piston rod extends, promptly lifting the cover plate 4 to facilitate subsequent nut handling.

[0029] The inner wall of the cover plate 4 is provided with a circulating cleaning mechanism, which includes a rotating sleeve 5. The outer side of the rotating sleeve 5 is rotatably connected to the inner wall of the cover plate 4 through a bearing. A worm gear 51 is fixedly sleeved on the upper end of the rotating sleeve 5. A water outlet hole 52 distributed in a ring array is opened on the lower end of the rotating sleeve 5. The water outlet hole 52 is carefully designed so that it can cover all corners of the inner ring of the nut when the water is sprayed, ensuring that there are no dead corners in the rinsing.

[0030] The lower end of the rotating sleeve 5 is fixedly connected to a cleaning brush 53 arranged in a ring array. The cleaning brush 53 is made of tough, wear-resistant and non-deformable bristles, which can not only penetrate deep into the thread gap of the nut to remove dirt, but also maintain a good cleaning effect during long-term use.

[0031] A circulation pump 54 is fixedly installed on the upper end of the cover plate 4. One end of the circulation pump 54 is fixedly connected to a water outlet pipe 55. One end of the water outlet pipe 55 is rotatably connected to the upper inner wall of the rotating sleeve 5 through a sealed bearing. This special connection method can ensure that the water flow is smoothly delivered to the inside of the rotating sleeve 5 without causing any obstruction to the rotation of the sleeve.

[0032] The other end of the circulating pump 54 is fixedly connected to the water inlet hose 56, and one end of the water inlet hose 56 is fixedly connected to the back of the cleaning tank 1, thus creating a complete water circulation loop, allowing the cleaning water to circulate repeatedly and fully exert the cleaning efficiency.

[0033] The upper end of the cleaning tank 1 is provided with symmetrically distributed limiting grooves 57. The inner wall of the limiting grooves 57 is slidably connected to limiting sliders 58. The opposing surfaces of the two limiting sliders 58 are fixedly connected to placement platforms 59. The placement platforms 59 serve as temporary support platforms for the nuts. Their positions can be flexibly adjusted according to cleaning needs. During the cleaning process, the placement platforms 59 can provide stable support for the nuts, ensuring that the nuts will not shift when subjected to water flow impact and brush washing, thus ensuring the consistency and accuracy of the cleaning effect.

[0034] The upper end of the placement platform 59 has a hexagonal positioning groove 510, which can accurately position the nut after it is placed in it, preventing unnecessary rotation or displacement during the cleaning process. The inner bottom wall of the hexagonal positioning groove 510 has a through hole 511, which provides a drainage channel for the sewage generated during the cleaning process and the metal impurities that fall off the brush, so that these wastes can quickly leave the area around the nut and avoid secondary pollution. At the same time, it also prevents the accumulation of impurities from affecting the normal operation of the cleaning brush 53.

[0035] A servo motor 512 is fixedly installed on the upper end of the cover plate 4. The output shaft of the servo motor 512 is fixedly installed with a worm gear 513 through a coupling. The outer surface of the worm gear 513 meshes with the tooth surface of the worm wheel 51. The cooperation between the worm gear 513 and the worm wheel 51 converts the high-speed rotation of the servo motor 512 into the appropriate speed required to rotate the sleeve 5, driving the cleaning brush 53 to clean the inner ring of the nut smoothly and powerfully. Moreover, the transmission process is smooth and the noise is low.

[0036] A drain pipe 6 is fixedly connected to one side of the cleaning tank 1. The drain pipe 6 is equipped with a precisely controlled solenoid valve. After the cleaning process is completed, the wastewater accumulated inside the cleaning tank 1 can be quickly and thoroughly discharged by opening the solenoid valve, preparing for the next round of cleaning operations.

[0037] The front of the cleaning tank 1 is equipped with an observation window 7, which is made of transparent and high-strength material. The operator can clearly observe the working status inside the cleaning tank 1 without opening the device, and keep abreast of key information such as the cleaning progress, water level and the clogging status of the filter screen 82, so as to make timely adjustment and maintenance decisions.

[0038] The front of the cleaning tank 1 is provided with a sealing slot 8, and a sealing frame 81 is movably inserted into the inner wall of the sealing slot 8. The back of the sealing frame 81 contacts the rear inner wall of the cleaning tank 1. The inner wall of the sealing slot 8 and the sealing frame 81 are finely polished to ensure that the sealing frame 81 can be tightly and smoothly inserted into it and maintain good sealing performance.

[0039] A filter screen 82 is fixedly fitted onto the inner wall of the sealing frame 81. The filter screen 82 is made of metal wire mesh with a suitable pore size or high-performance filter material. It can effectively intercept metal impurities in the cleaning water and prevent them from flowing back to the circulation pump 54 and causing damage. It also has good water permeability and will not cause excessive resistance to water circulation.

[0040] A handle 83 is fixedly connected to the front of the sealing frame 81. The handle 83 is convenient for operators to grip and apply force. When it is necessary to collect and clean the metal impurities accumulated on the filter screen 82, the sealing frame 81 can be pulled out from the sealing slot 8 by simply pulling the handle 83. The operation is convenient and efficient.

[0041] The working process of this utility model:

[0042] Step 1: Place the nut to be cleaned in the hexagonal positioning groove 510 for positioning, then start the piston rod of the servo electric cylinder 3 to retract, thereby driving the cover plate 4 to move down and contact the upper end of the cleaning tank 1 to prevent water from splashing out during cleaning. The movement of the cover plate 4 also drives the cleaning brush 53 to move into the inside of the nut through the rotating sleeve 5. Start the circulation pump 54 to work. The circulation pump 54 delivers the clean water filtered at the bottom of the filter screen 82 to the outlet pipe 55 through the water inlet hose 56, and then delivers it to the rotating sleeve 5 through the outlet pipe 55. Then, it sprays water through the water outlet hole 52 to rinse the inner ring of the nut.

[0043] Step 2: Simultaneously start the servo motor 512 to drive the worm gear 513 to rotate. The rotation of the worm gear 513 drives the rotating sleeve 5 to rotate through the meshing worm wheel 51, thereby driving the cleaning brush 53 to rotate and clean the inner ring of the nut. The metal impurities and sewage that are washed off are discharged downward through the through hole 511. After the metal impurities are intercepted by the filter screen 82, the clean water flowing into the bottom of the cleaning tank 1 can be reused.

[0044] Step 3: After cleaning, turn off the circulation pump 54 and servo motor 512, then start the piston rod of servo electric cylinder 3 to extend, driving the cover plate 4 to rise and move until the cleaning brush 53 is separated from the nut. The cleaned nut can then be taken out and replaced. After a period of use, open the solenoid valve on the drain pipe 6 to drain the sewage inside the cleaning tank 1. Then, move the sealing frame 81 with the handle 83 to pull out the sealing slot 8, so that the metal impurities on the filter screen 82 can be collected and cleaned. By replacing the placement platform 59 and the cleaning brush 53, the inner ring of nuts of different sizes can be cleaned.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
