Description

Technical Field

[0001] This utility model relates to the field of salt spray testing technology, and in particular to a salt spray testing machine for processing fasteners. Background Technology

[0002] The corrosion resistance of fasteners (such as bolts, nuts, washers, etc.) is a key indicator for assessing their service life. Salt spray test chambers accelerate the testing of the corrosion resistance of fastener surface treatments (such as electroplating, phosphating, coatings) by simulating salt-rich corrosive environments such as the ocean and industrial atmosphere.

[0003] By comparing a fastener salt spray testing device with patent publication number CN222979385U, it was found that in this solution, the screw is supported by a material carrier platform, and each screw to be tested is independently erected by the material hole opened on the platform. However, the screw is always in a vertical position in the material hole. As a result, the sprayed salt spray may not be evenly sprayed onto the screw surface, and the grooves or slots of the screw may not be evenly contacted with the salt spray. This may lead to deviations in the final test results, affecting the accuracy of the test results. Utility Model Content

[0027] In this embodiment: the test mechanism includes a salt spray generator 301 installed at the bottom of the salt spray chamber 100, a salt spray nozzle 302 installed at the top of the salt spray generator 301, a baffle 303 above the salt spray nozzle 302, the baffle 303 being a cone with the small end facing down, collection covers 304 on both sides of the inner wall of the salt spray chamber 100, and heating tubes 305 symmetrically arranged on both sides of the salt spray generator 301 along the front-back direction.

[0028] In this embodiment: the fixing mechanism includes two supports 201 disposed on the upper end of the salt spray chamber 100. The two supports 201 are symmetrically arranged in the front-back direction. The supports 201 are L-shaped. Multiple placement slots are opened on the upper end of the supports 201. A rotating frame 207 is provided between two placement slots. Multiple rotating plates 209 are installed inside the rotating frame 207. The rotating plates 209 are rotatably connected to the rotating frame 207. A rotating handle 210 is fixed to the front end of the rotating plate 209. A connecting frame 211 is fixed to the upper end of the rotating plate 209. A fixing ring 212 is fixed to the upper end of the connecting frame 211. The inner wall of the fixing ring 212 slides upward. Multiple clamping blocks 213 are movably installed, and the multiple clamping blocks 213 are distributed around the center of the fixed ring 212. The clamping blocks 213 are made of corrosion-resistant material. A pre-tightening spring is connected between the clamping blocks 213 and the fixed ring 212. The upper end of the clamping blocks 213 is inclined. Multiple rollers 214 are rotatably installed on the upper end of the clamping blocks 213. A moving groove 208 is opened on the upper end of the rotating frame 207 near the connecting frame 211. A cover door 215 is rotatably installed on the upper end of the salt spray box 100. An adjustment structure for adjusting the tilt angle of the rotating frame 207 is provided between the rotating frame 207 and the bracket 201.

[0029] The adjustment structure includes a connecting shaft 204 disposed between the placement slot and the rotating frame 207. The connecting shaft 204 is rotatably engaged with the placement slot and fixedly connected to the rotating frame 207. A rotating shaft 202 is rotatably mounted on the inner wall of the bracket 201 near the placement slot. A lower gear 203 is fixed on the rotating shaft 202, and an upper gear 205 is fixed on the connecting shaft 204. The upper gear 205 meshes with the lower gear 203. Multiple rotating shafts 202 are driven by belt pulleys. A rotary motor 206 is mounted on the rotating end of the rotating shaft 202. The output end of the rotary motor 206 is fixed to the rotating end of the rotating shaft 202 through a coupling. Multiple clamping blocks 213 in the fixing mechanism clamp and fix fasteners of different diameters.

Then, close the cover 215, add water and salt water to the inside of the salt spray chamber 100, then turn on the heating tube 305 to heat the water inside, and then start the salt spray generator 301 to generate a large amount of salt spray. Use the salt spray nozzle 302 to spray the salt spray upward, so that the salt spray is distributed inside the salt spray chamber 100.

[0031] Then, the rotary motor 206 is started, using a pulley to drive multiple rotating shafts 202 to rotate, which in turn drives multiple lower gears 203 to rotate. The lower gears 203 mesh with the upper gears 205, causing the upper gears 205 to drive the connecting shaft 204 to rotate, which in turn drives the rotating frame 207 to rotate, causing the fasteners in the clamp to swing back and forth, so that the surface of the fasteners can fully contact the salt spray, and the salt spray can evenly cover the surface of the fasteners, especially distributing the salt spray in the grooves and slots of the fasteners, ensuring more uniform contact between the salt spray and the fasteners, and improving the accuracy of the test results.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
