Description

Technical Field

[0001] The present invention relates to the field of processing and cleaning, and particularly to a cleaning device for high-strength fasteners. Background Technique

[0002] With the rapid development of the high-end equipment manufacturing industry, high-strength fasteners are increasingly widely used. Such fasteners usually adopt materials such as alloy steel and titanium alloy, and are processed through processes such as quenching and tempering heat treatment and surface coating to meet the stringent working conditions requirements such as high load, corrosion resistance, and long service life. However, during the production, transportation, and assembly processes, the surfaces of fasteners are often contaminated with various pollutants such as metal chips, rust preventive oil, etc. If these pollutants are not thoroughly cleaned, they will often directly affect the performance and reliability of subsequent fasteners.

[0003] In the current technology, during the automated cleaning process of high-strength fasteners, the existing cleaning line faces a key technical problem: when the same production line needs to process fasteners with large size differences, the fixed spray pressure and ultrasonic frequency cannot adaptively match the cleaning requirements of workpieces of different specifications. This results in surface damage to small-sized fasteners under excessive pressure or strong cavitation effects, while large-sized fasteners have blind spots and residual pollutants at the thread roots due to insufficient cleaning energy, seriously affecting product consistency and reliability.

[0004] Therefore, a cleaning device for high-strength fasteners is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a cleaning device for high-strength fasteners to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A cleaning device for high-strength fasteners, including a drum sieve and a pre-cleaning device. Inside the drum sieve, there are multiple groups of power drums arranged in a progressive manner. The bottom end of the drum sieve is connected to an inclined channel for distinguishing materials of different specifications. Inside the inclined channel, there is a baffle for separating materials. The discharge end of the inclined channel is connected to a cleaning device, and inside the cleaning device, there are two partition plates forming a cleaning chamber for cleaning materials of corresponding specifications.

[0007] Preferably, one side of the cleaning device is connected to a water delivery pipe, the input end of the water delivery pipe is connected to a pump, and strainers for placing materials of different specifications are respectively placed inside different cleaning chambers.

One side of the driving gear meshes with an intermediate gear. One side of the intermediate gear meshes with a driven gear. One side of the driven gear is connected to a brush. The intermediate gear and the driven gear are both rotatably connected to the outer side wall of the pre-cleaning device. The brush is rotatably connected to the inside of the pre-cleaning device.

[0009] Preferably, a conveyor belt for transporting materials is connected inside the pre-cleaning device. A plurality of conveyor rollers are arranged inside the conveyor belt. One end of one of the conveyor rollers is rotatably connected to both ends of the drive motor and is connected to a support frame.

Two partition plates 19 are connected inside the cleaning device 4 to form a cleaning chamber for cleaning corresponding specifications of materials. After separation, the fasteners fall into the cleaning device 4 through the inclined channel 3 for cleaning.

[0017] In this embodiment, a water delivery pipe 18 is connected to one side of the cleaning device 4. The input end of the water delivery pipe 18 is connected to a pump 16. Fishing nets 7 for different specifications of materials are respectively placed inside different cleaning chambers. Fasteners of different specifications fall into the fishing nets 7 inside the cleaning chamber, which is convenient for taking out the fasteners from the cleaning device after cleaning. A plurality of cleaning holes are provided on the surface of the fishing net 7, and a holding rod 24 is installed inside the fishing net 7 to facilitate taking out the fishing net 7 inside the cleaning chamber.

[0018] In this embodiment, the pre-cleaning device 10 includes a driving motor 11 connected to the outer side wall of the pre-cleaning device 10.
