[0016] Depend on Figures 1 to 3 A surface treatment device for rivet processing is provided, comprising a first trough body 1, a second trough body 2 and a support leg 3, a crossbeam 4 is fixed on the support leg 3, a trolley running mechanism 5 is run on the left and right of the crossbeam 4, a hydraulic cylinder 6 is installed on the trolley running mechanism 5, a cross plate 7 is fixed at the lower end of the hydraulic cylinder 6, side plates 8 are fixed on the left and right sides of the cross plate 7, a first rotating shaft 9 and a second rotating shaft 10 are rotatably connected between the two side plates 8, the first rotating shaft 9 is located above the second rotating shaft 10, a first gear 11 is coaxially fixed to the first rotating shaft 9, a second gear 12 meshing with the first gear 11 is coaxially fixed to the second rotating shaft 10, a roller 13 is coaxially fixed to the second rotating shaft 10, a plurality of first through holes 14 are evenly arranged on the left and right ends of the roller 13, a plurality of second through holes 15 are evenly arranged on the circumference of the roller 13, an arc-shaped cover plate 16 is hinged on the outer edge surface of the roller 13, and a buckle is installed between the arc-shaped cover plate 16 and the outer edge surface of the roller 13.

[0017] The buckle comprises an elastic arc-shaped block 17 and a slot 18 . One end of the arc-shaped block 17 is fixed on the arc-shaped cover plate 16 . The slot 18 is fixed on the roller 13 . A cylinder 19 matching the slot 18 is fixed inside the arc-shaped block 17 .

[0018] An organic solvent is placed in the first tank 1, and the organic solvent effectively removes oil stains on the surface of the rivet.

[0019] An acidic solution is placed in the second tank 2, and the acidic solution can effectively remove rust on the surface of the rivet.

[0020] In order to ensure a suitable rotation speed of the first rotating shaft 9, a motor 20 is fixed on the side plate 8, and the motor 20 is coaxially fixedly connected to the first rotating shaft 9 via a reducer.

[0021] In order to facilitate the opening and closing of the arc-shaped cover plate 16 , a handle 21 is fixed on the arc-shaped cover plate 16 .

[0022] When the utility model is in use, the first rotating shaft 9, the second rotating shaft 10, the first gear 11, the second gear 12, the roller 13, the arc cover plate 16 and the buckle are all made of plastic material. The rivets are first degreased and derusted before electroplating. An organic solvent is placed in the first tank body 1, and an acid solution is placed in the second tank body 2. The arc cover plate 16 is opened, and a plurality of rivets are poured into the roller 13. The diameter of the rivet rod is larger than the diameter of the first through hole 14, and the diameter of the rivet rod is larger than the diameter of the second through hole 15, so as to prevent the rivet rod from being stuck in the first through hole 14 or the second through hole 15. After the rivets are placed, the arc cover plate 16 is closed, and the arc clamping block 17 is pressed by hand to clamp the cylinder 19 in the clamping groove 18, and then the buckle is clamped to realize the closing of the arc cover plate 16 and the roller 13. The roller 13 is moved left and right to a suitable position above the first tank body 1 through the trolley running mechanism 5, and the trolley running mechanism 5 is closed and started. The hydraulic cylinder 6 drives the horizontal plate 7 and the side plate 8 to move downward as a whole, and then the drum 13 descends into the first tank body 1. The organic solvent in the first tank body 1 completely submerges the rivet. The first rotating shaft 9 is located above the second rotating shaft 10. The motor 20 is located above the organic solvent to ensure the safety of the motor 20. The motor 20 is started. The motor 20 drives the first rotating shaft 9 to rotate through the reducer. The first rotating shaft 9 drives the first gear 11 to rotate. The first gear 11 drives the second gear 12 to rotate. The second gear 12 drives the second rotating shaft 10 to rotate. The second rotating shaft drives the drum 13 to rotate. The drum 13 drives the rivet to rotate in the organic solvent. Under the joint action of the first through hole 14 and the second through hole 15, the fluidity of the organic solvent in the drum 13 is increased, and the degreasing efficiency of the rivet surface is improved. The rivets in the drum 13 are in a scattered state, which increases the contact area between the rivets and the organic solvent, and the degreasing effect is good.

[0023] Similarly, after the rivet is degreased, the hydraulic cylinder 6 drives the roller 13 to move upward to a suitable height, starts the trolley movement mechanism, and the trolley movement mechanism drives the roller 13 to move rightward to above the second tank body 2. The hydraulic cylinder 6 drives the roller to move downward into the second tank body 2. The acid solution completely covers the rivet, and the roller 13 drives the rivet to rotate in the acid solution. The acid solution effectively removes the rust on the surface of the rivet, with high work efficiency, time-saving and labor-saving, and a high degree of automation. After the rivet is degreased and rusted, the hydraulic cylinder 6 lifts the roller 13 and opens the cover plate, so that the treated rivets can be collected for the next step of processing.

[0024] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the protection scope of the technical solution of the utility model.
