Description

Technical Field

[0001] This utility model relates to the field of bolt cleaning technology, specifically to a high-efficiency bolt cleaning device. Background Technology

[0002] A bolt is a cylindrical threaded fastener that is fitted with a nut. It consists of two parts: a head and a shank (a cylinder with external threads). It is used to fasten two parts with through holes. Bolts are also known as the "rice of industry" because they are widely used in daily life and industrial manufacturing.

[0003] To ensure the long-term safe operation of bolted equipment, it is necessary to regularly replace and maintain the bolts of the connecting parts. This requires cleaning the bolts, especially for some large bolts, such as bolts of model DIN 2510M110×6, whose total length can reach one meter. Currently, there is a lack of corresponding automatic cleaning equipment, which is inconvenient to use.

[0004] Based on this, the present invention designs a high-efficiency bolt cleaning device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-efficiency bolt cleaning device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency bolt cleaning device includes an upper sealing housing and a lower sealing housing. A bolt rotating assembly and a liquid spraying cleaning assembly are installed between the upper and lower sealing housings. The bolt rotating assembly includes a servo motor, a reducer, a coupling, a roller, and a nylon roller. The servo motor is installed at the top of the lower sealing housing. The reducer is connected to the servo motor and the roller via the coupling. The nylon roller is fixed to the side walls of the roller near both ends. The liquid spraying cleaning assembly includes a moving mechanism, a centrifugal pump, a liquid storage tank, a suction pipe, a switch ball valve, a brush cover, a roller brush, and a nozzle. The moving mechanism is installed at the top of the lower sealing housing. The centrifugal pump, liquid storage tank, suction pipe, and switch ball valve are located inside the lower sealing housing.

[0008] Furthermore, the moving mechanism includes a linear module, a mounting base plate, a cable chain, a vertical cylinder, a support plate, a mounting plate, and a horizontal cylinder. The linear module is fixed to the top of the lower sealing box. The mounting base plate is slidably mounted through the linear module. The cable chain is mounted on the side of the mounting base plate. The vertical cylinder is fixed to the mounting base plate. The support plate and the mounting plate are fitted together at the piston rod end inside the vertical cylinder. The horizontal cylinder is mounted on the mounting plate. The brush cover is mounted at the piston rod end inside the horizontal cylinder.

[0009] Furthermore, the lower sealing box is equipped with casters at the four corners of its bottom, and a baffle is fixed at the top of the lower sealing box between the linear module and the roller.

[0010] Furthermore, a one-way valve is installed at the connection point between the liquid extraction pipe and the liquid storage tank.

[0011] Furthermore, it also includes a pneumatic drying component, which includes a fan and a hot air gun. The fan is installed inside the lower sealed housing, and the fan and the hot air gun are connected. The hot air gun is fixed to the side of the mounting base plate.

[0012] Furthermore, a through groove is provided at the top of the lower sealing box at the position of the bolt rotating assembly, the liquid storage tank is located below the through groove and slides inside the lower sealing box, and a filter screen is installed on the inner wall of the liquid storage tank.

[0015] Beneficial effects

[0016] 1. By setting up a bolt rotation assembly and a liquid spraying cleaning assembly, while the nozzle sprays cleaning liquid onto the bolt, the bolt rotation assembly drives the bolt to rotate, so that the cleaning liquid is evenly sprayed onto the bolt surface. At the same time, the rotating bolt is brushed by roller brushes to achieve efficient cleaning of the bolt surface.

[0017] 2. By incorporating a moving mechanism, the position of the brush cover can be adjusted to bring it closer to the bolts for easier cleaning. Casters facilitate device movement. Baffles prevent liquid splashing onto the linear module during nozzle and roller brush operation, protecting it. A one-way valve prevents liquid backflow. A pneumatic drying component, with a fan operating and a hot air gun, dries the bolts, removing residual cleaning fluid. Simultaneously, the bolts rotate continuously under the drive of the bolt rotation assembly, ensuring even heating and thorough drying. A trough and filter allow cleaning fluid to return to the storage tank via the trough and be filtered for reuse. A control panel facilitates control of the electrical components within the device.

Inside the horizontal cylinder 22, at the piston rod end, a moving mechanism is used to adjust the position of the brush cover 12, making it easier to position it close to the bolt for easy bolt cleaning; four casters 23 are installed at the bottom corners of the lower sealing box 2 to facilitate the movement of the device; a baffle 24 is fixed at the top of the lower sealing box 2 between the linear module 16 and the roller 6 to prevent liquid from splashing onto the linear module 16 when the nozzle 14 and roller brush 13 are working, thus protecting it; a one-way valve 25 is installed at the connection between the liquid extraction pipe 10 and the liquid storage tank 9 to prevent liquid backflow;

[0032] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, it also includes a pneumatic drying component, which includes a fan 26 and a hot air gun 27. The fan 26 is installed inside the lower sealing box 2, and the fan 26 and the hot air gun 27 are connected. The hot air gun 27 is fixed to the side of the mounting base plate 17. A through groove 28 is opened at the top of the lower sealing box 2 at the position of the bolt rotating assembly. The liquid storage tank 9 is located below the through groove 28 and slides inside the lower sealing box 2. A filter screen 29 is installed on the inner wall of the liquid storage tank 9. The liquid storage tank 9 is welded from 304 stainless steel, and the filter screen 29 is a 120-mesh stainless steel filter screen.

[0033] In this embodiment of the invention, during use, an external connecting pipe is used to connect the centrifugal pump 8 and the nozzle 14 via the connector 15. The upper sealing housing 1 is opened, and the bolt to be cleaned is placed on the roller 6 so that the threaded part contacts the nylon roller 7. After placement, the upper sealing housing 1 is closed, and the servo motor 3 is started via the control panel 30. With the cooperation of the reducer 4 and the coupling 5, the roller 6 and the nylon roller 7 are driven to rotate, thereby driving the bolt to rotate. During the rotation of the bolt, the spray cleaning assembly uses a moving mechanism to move the brush cover 12 above the bolt, and the centrifugal pump 8...

At the same time, the roller brush 13 scrubs the bolt surface to achieve efficient cleaning of the bolt. The liquid in the cleaning process returns to the storage tank 9 through the channel 28, and is filtered by the filter screen 29 for reuse. After cleaning, the centrifugal pump 8 stops working, the fan 26 runs, and the bolt is dried by the hot air gun 27 to dry the residual cleaning solution on the bolt surface. At the same time, the bolt continues to rotate under the drive of the bolt rotating assembly to ensure uniform heating and thorough drying.

[0034] In this embodiment of the invention, a pneumatic drying component is provided, and the fan 26 operates to dry the bolts using a hot air gun 27, blowing away any residual cleaning fluid on the bolt surface. Simultaneously, the bolts rotate continuously under the drive of the bolt rotating assembly, ensuring uniform heating and thorough drying.
