Description

Technical Field

[0001] This utility model relates to the technical field of product testing equipment, and in particular to a salt spray corrosion testing machine. Background Technology

[0002] Salt spray corrosion is a common and highly destructive form of atmospheric corrosion. The main corrosive component is sodium chloride from the ocean, originating primarily from marine and inland saline-alkali regions. The corrosion of metal surfaces by salt spray is caused by chloride ions penetrating the oxide and protective layers of the metal surface and reacting electrochemically with the internal metal. Simultaneously, because chloride ions contain a certain amount of water and energy, they are easily adsorbed in the crevices of the metal surface, replacing oxygen in the oxide layer and converting insoluble oxides into soluble chlorides. This activates the passivated surface, causing damage to the product. Therefore, after the metal products are manufactured, they must undergo salt spray corrosion testing. Currently, salt spray corrosion testing is generally conducted using a salt spray corrosion testing machine.

[0003] However, in existing salt spray corrosion testing machines, the distance between the device fixing platform and the bottom of the machine casing, and the distance between the device fixing platform and the nozzle, are fixed. Therefore, when conducting salt spray corrosion tests on metal products with a volume much smaller than the test chamber volume, it will result in an excessive spraying distance of the nozzle, causing waste and incomplete spraying, which is quite troublesome. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a salt spray corrosion testing machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A salt spray corrosion testing machine, comprising:

[0007] The machine body has a test chamber for testing products.

[0008] A control panel, located on one side of the machine body, is used to control the start-up or shutdown of the machine body;

[0009] A test bench, movably mounted within the test chamber, is used to place the product;

[0010] A lifting and adjusting mechanism is provided inside the test chamber and is used to move the test platform up and down to adjust the relative position between the test platform and the test chamber. The test platform is movably connected to the lifting and adjusting mechanism.

[0011] Several salt spray nozzles are movably disposed within the test chamber for treating products placed on the test bench;

[0012] A nozzle adjustment mechanism is located inside the test chamber and is used to adjust the relative positional relationship between the salt spray nozzles. The salt spray nozzles are connected to the nozzle adjustment mechanism.

[0013] As described above, in a salt spray corrosion testing machine, the lifting adjustment mechanism includes vertical adjusting screws and multiple vertical guide rods respectively located at the four corners of the test chamber, and an adjustment knob located at the upper end of the vertical adjusting screws. The test platform is sleeved with the multiple vertical guide rods and threadedly connected to the vertical adjusting screws.

[0014] As described above, in a salt spray corrosion testing machine, the four corners of the test platform are respectively provided with threaded connection parts and multiple guide parts. The threaded connection parts are threadedly connected to the vertical adjusting screw, and the multiple guide parts are respectively sleeved on the corresponding vertical guide rods.

[0015] As described above, in a salt spray corrosion testing machine, the nozzle adjustment mechanism includes fixed rods symmetrically arranged on both sides of the upper end of the test chamber along the length direction, and several adjusting crossbars slidably sleeved between the two fixed rods, with several salt spray nozzles slidably mounted on the corresponding adjusting crossbars.

[0016] In the salt spray corrosion testing machine described above, a first locking structure for locking the relative positional relationship between the fixed rod and the adjusting crossbar is also provided.

[0017] As described above, in a salt spray corrosion testing machine, the first locking structure includes a first sliding collar disposed at both ends of the adjusting crossbar and respectively sleeved on the fixed rod, and a first locking screw screwed onto the first sliding collar and capable of pressing against the fixed rod.

[0018] In the salt spray corrosion testing machine described above, a second locking structure is also provided between the adjusting crossbar and the salt spray nozzle for locking the relative positional relationship between the two.

[0019] As described above, in a salt spray corrosion testing machine, the second locking structure includes a second sliding collar disposed at the upper end of the salt spray nozzle and sleeved on the adjusting crossbar, and a second locking screw screwed onto the second sliding collar and capable of pressing against the adjusting crossbar.

[0020] In the salt spray corrosion testing machine described above, there are two adjusting crossbars, and a number of salt spray nozzles are equally distributed on the two adjusting crossbars.

[0021] As described above, a salt spray corrosion testing machine is further provided with a cover hinged to the machine body for covering or exposing the test chamber.

[0022] The beneficial effects of this utility model are: the structure of this application is simple. Through the coordinated setting of the lifting adjustment mechanism and the nozzle adjustment mechanism, during the test, the lifting adjustment mechanism can be used to adjust the moving test platform to a suitable height according to the size of the test product. This ensures that the test product is placed in the center of the test chamber when placed on the test platform. At the same time, the nozzle adjustment mechanism can be used to adjust the moving salt spray nozzle to the periphery of the test product. This is practical and convenient, avoiding waste and incomplete spraying caused by excessive spraying distance of the salt spray nozzle, reducing production costs and ensuring the stability of the test.
