AI Technical Summary
Existing salt spray corrosion test chambers cannot ensure that black passivated parts come into complete contact with salt spray, resulting in inaccurate corrosion resistance test results.
A high-precision salt spray corrosion test chamber was designed. The automatic flipping mechanism enables the parts to fully contact the salt spray. The chamber includes a rotating component, a moving component, and a driving component. The first and second reciprocating screws drive the movement of the rotating plate and the movable column, so that the parts can be flipped to different positions to contact the salt spray.
This ensures full contact between all parts and the salt spray, improving the accuracy of corrosion resistance tests.

[0019] The embodiment of the application discloses a high-precision salt spray corrosion test box for black passivation spare parts products. The rotation of the first reciprocating lead screw 711 drives the rotating shaft 30 and the rotating plate 40 to rotate. The second reciprocating lead screw 721 drives the movement of the movable column 60. The spare parts on the rotating plate 40 on one side of the rotating shaft 30 can be turned over to the side of the rotating plate 40. The position of the spare parts in contact with the rotating shaft 30 is exposed to the smoke and fully contacts with the salt spray. The test result is more accurate.
[0020] In order to better understand the above technical solutions, the above technical solutions will be described in detail in combination with the description of the drawings and the specific embodiments.
[0021] Please refer to Figure 1 and Figure 2The embodiment provides a high-precision salt spray corrosion test box for black passivation spare part products, which comprises a box body 10, a plurality of fixed plates 20 arranged in the box body 10, a rotating shaft 30 rotatably connected to one side of the bottom of the fixed plates 20, a rotating plate 40 fixedly arranged on one side of the rotating shaft 30, a plurality of fixed blocks 90 fixedly arranged on one side of the fixed plate 20 close to the rotating plate 40, a plurality of fixed columns 50 fixedly arranged on one side of the top of the fixed plates 20, a plurality of movable columns 60 movably connected to one side of the top of the rotating plates 40, a cavity arranged in the box body 10, and a turnover mechanism 70 arranged in the cavity and used for driving the rotating shaft 30 to rotate and the movable column 60 to move. The bottom of the automobile black passivation spare part is placed on the top of the fixed block 90 in the rotating plate 40, so that the plurality of spare parts are placed on the rotating plate 40, the top of the longer spare part can be placed on the movable column 60, and the contact area between the bottom of the spare part and the fixed block 90 is small. When the rotating plate 40 rotates and the movable column 60 moves, the spare parts placed on the rotating plate 40 and the movable column 60 can be turned to one side of the fixed plate 20 and the fixed column 50, the contact position of the spare part with the inside of the box body 10 changes, so that each position of the spare part can contact the salt spray in the box body 10, and the corrosion resistance of the surface of the spare part can be tested more accurately.
[0022] Please refer to Figures 1-4The turnover mechanism 70 comprises a rotating assembly 71, a moving assembly 72, and a driving assembly 73.

The plurality of gears 714 are meshingly connected to the top of the rack 712 and are fixedly connected to the ends of the plurality of rotating shafts 30 extending into the inside of the cavity. The reciprocating movement of the rack 712 is driven by the rotation of the first reciprocating lead screw 711 in the cavity. The sliding of the first limiting block 713 at the bottom of the rack 712 in the first limiting groove limits the movement of the rack 712 to prevent the rack 712 from rotating with the first reciprocating lead screw 711. The reciprocating movement of the rack 712 drives the gears 714 meshed with the top to drive the rotating shafts 30 and the rotating plates 40 to rotate towards the fixed plate 20 and then reset, so that the spare parts on the fixed plate 20 can be turned over with the rotation of the rotating plates 40, thereby changing the contact position of the spare parts with the inside of the box body 10 and enabling the contact position of the spare parts with the rotating plates 40 and the fixed blocks 90 to be in contact with the salt mist, so as to more comprehensively test the surface corrosion resistance of the spare parts.
