Description

Technical Field

[0001] The utility model relates to the technical field of washer cleaning, in particular to an efficient flat washer cleaning device. Background Technique

[0002] A washer refers to a part placed between the connected part and the nut. Generally, it is a flat metal ring used to protect the surface of the connected part from being scratched by the nut and to disperse the pressure of the nut on the connected part. During the production process of the washer, oil substances such as lubricating oil are used for surface treatment. The lubricating oil on the surface of the washer will adsorb impurities such as dust, thus affecting the use of the washer. Therefore, before the washer is officially used or before it leaves the factory, it needs to be cleaned.

[0003] The utility model with the application number CN201921829769.9 discloses a washer cleaning device. By setting a rotating turntable and evenly arranging a plurality of placement racks for placing washers on the turntable, and cleaning brushes are arranged on both sides of the placement rack, more washers can be cleaned at one time, improving the efficiency of automatic washer cleaning.

[0004] The above device places the washers through placement columns, and the washers are stacked from bottom to top, with adjacent washers fitting together and having no gap between adjacent washers. The cleaning brushes cannot contact the front and back surfaces of the washers, and the cleaning brushes can only clean the outer sides of the washers, unable to clean the front and back surfaces of the washers, and unable to clean the impurities thoroughly, resulting in poor cleaning effect.

[0005] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model

[0013] Further, two threaded grooves with opposite spiral directions are provided on the bidirectional threaded screw rod. The two moving sliders are respectively threadedly connected to the two threaded grooves. A rotating handle is installed at one end of the bidirectional threaded screw rod.

[0014] Compared with the prior art, the technical solution has the following beneficial effects:

[0015] By means of the air release valve, the gas is conveyed from bottom to top, and the rubber inflatable rings can be inflated from bottom to top in sequence. The flat gaskets are sleeved on the hollow rod in sequence. At the same time, multiple flat gaskets can be cleaned. The topmost rubber inflatable ring fixes the topmost flat gasket to prevent the flat gasket from falling off. The adjacent flat gaskets can be separated by the rubber inflatable rings. There is an interval between adjacent flat gaskets, and the flat gaskets can be fully cleaned. The cleaning brushes can fully contact the flat gaskets, improving the cleaning effect.

[0016] By rotating the bidirectional threaded screw rod to drive the two moving sliders and the moving side plates to approach each other, the moving side plates drive the outer cleaning brushes to move.

A plurality of air release valves 11 are connected to the U-shaped inflatable pipe 7. The plurality of air release valves 11 are distributed between adjacent inflating nozzles 10.

[0025] Remove the box cover 2 from the cleaning box 1, and sequentially put the flat washers on the hollow rods 6. The lowermost flat washer lands on the limiting disk 8. At the same time, the U-shaped inflatable pipe 7 inflates the rubber inflatable rings 9 through the inflating nozzles 10. The lowermost rubber inflatable ring 9 is first filled with gas. After the rubber inflatable ring 9 below is filled with gas, the air pressure exceeds the set value of the air release valve 11, and the gas is conveyed upward through the air release valve 11 to inflate the rubber inflatable ring 9 above. The rubber inflatable rings 9 can be inflated in sequence from bottom to top. The flat washers are sequentially put on the hollow rods 6. At the same time, multiple flat washers can be cleaned. The uppermost rubber inflatable ring 9 fixes the uppermost flat washer to prevent the flat washer from falling off. The adjacent flat washers can be separated by the rubber inflatable rings 9. There is an interval between adjacent flat washers, so that the flat washers can be fully cleaned. The cleaning brushes can fully contact the flat washers, improving the cleaning effect. The hollow rotating shaft 4 drives the rotating disk 5 and the hollow rods 6 to rotate.

[0026] Refer to the attached Figure 1 、the attached Figure 2 and the attached Figure 3 According to the attached drawings, a fixed column 12 is installed at the center of the bottom of the box cover 2. Inner cleaning brushes 13 are arranged around the fixed column 12. A transverse through groove 14 is provided on the box cover 2. A fixed bracket 15 is installed at the center of the top of the box cover 2. A bidirectional threaded lead screw 16 is rotatably connected to the fixed bracket 15. Two moving sliders 17 are threadedly connected to the bidirectional threaded lead screw 16. The two moving sliders 17 are slidably connected to the transverse through groove 14. Two moving side plates 18 are arranged below the box cover 2. The two moving side plates 18 are respectively fixedly connected to the two moving sliders 17. Outer cleaning brushes 19 are installed on the moving side plates 18.

The fixing column 12 and the inner cleaning brush 13 are located between the two hollow rods 6, and the inner cleaning brush 13 contacts the flat washer. The operator rotates the double-threaded screw rod 16. The rotation of the double-threaded screw rod 16 drives the two moving sliders 17 to move relatively. The two moving sliders 17 slide along the transverse through groove 14. The moving slider 17 drives the moving side plate 18 to move. The two moving side plates 18 approach each other. The moving side plate 18 drives the outer cleaning brush 19 to move. The outer cleaning brush 19 contacts the flat washer, and the outer cleaning brush 19 extends into the gap between adjacent flat washers, which can fully clean the front and back sides and the outer ring of the flat washer, improving the cleaning effect.

[0028] Refer to the attached drawings of the specification Figure 1 and the attached drawings of the specification Figure 4 Inside the hollow rotating shaft 4, there is a rotary joint 20. One end of the rotary joint 20 is communicated with the U-shaped inflatable pipe 7. A fixed bottom plate 21 is installed between the fixed legs 3. An air pump 22 is installed on the fixed bottom plate 21. The air inlet end of the air pump 22 is installed with an air delivery pipe 23.
