[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the embodiment, Figure 1-4 A salt spray machine for testing cavity filling raw materials is provided, comprising a box body 1, an atomizing chamber 2 is arranged inside the box body 1, an atomizing nozzle 3 is arranged inside the atomizing chamber 2, a water injection tank 4 is arranged inside the box body 1 and located on the right side of the atomizing chamber 2, a box cover 5 is arranged on the top of the atomizing chamber 2, placement seats 6 are symmetrically arranged on the left and right sides of the atomizing chamber 2, placement covers 7 are arranged on the tops of the two placement seats 6, a plurality of test racks 8 are arranged inside the placement seats 6, and a loose-tight component 9 for driving the placement cover 7 to open and close is arranged on the inner side wall of the atomizing chamber 2.

[0025] Reference Figure 1 , wherein a sealing groove 10 is provided at a position where the surface of the box body 1 contacts the box cover 5;

[0026] With the above-mentioned structural arrangement, when the salt spray machine is working, clean water is injected into the sealing groove 10 after the box cover 5 is closed, so as to improve the sealing effect of the box cover 5 and prevent the salt spray from seeping out of the gap of the box cover 5 and corroding the equipment housing.

[0027] Reference Figure 2-4 , wherein the placement seat 6 includes a moving groove 61, the inside of the two placement seats 6 are each provided with a moving groove 61, and the opposite side of the placement seat 6 is provided with a limiting groove 62 connected to the moving groove 61, and a plurality of springs 63 are installed in parallel and equidistantly at the bottom end of the inner side of the moving groove 61, and a lifting plate 64 is fixedly installed at the top of the plurality of springs;

[0028] Through the above-mentioned structural arrangement, after the placement cover 7 rises to release the fixation of the placement seat 6, the spring 63 resets to lift the lifting plate 64, so that the test frame 8 and the sliding plates 81 at both ends thereof leave the movable groove 61 and the limiting groove 62. At the same time, it is also convenient for workers to move and adjust the position of the test frame 8 on the lifting plate 64 through the sliding plates 81 on both sides as needed. When the placement cover 7 is separated from the placement seat 6, the spring 63 resets to push the test frame 8 out through the lifting plate 64 for workers to take and replace.

[0029] Reference Figure 2-4 , wherein the interior of the placement cover 7 is provided with a moving groove 61 and a limiting groove 62 symmetrical to those on the placement seat 6, and the moving groove 61 and the limiting groove 62 on the placement cover 7 and the placement seat 6 are opposite in position;

[0030] Through the above-mentioned structural setting, after the position of the test frame 8 is adjusted, the elastic component 9 is used to control the downward movement of the placement cover 7. After the placement cover 7 and the placement seat 6 are closed, the moving groove 61 and the limiting groove 62 inside the two cooperate to fix the sliding plate 81 on the test frame 8 to prevent it from moving.

[0031] Reference Figure 2-4 , wherein the test frame 8 includes a sliding plate 81, the size of the test frame 8 is adapted to the limiting groove 62, the sliding plates 81 are fixedly installed at both ends of the test frame 8, and the length of the sliding plate 81 is equal to the moving groove 61 formed by the placement cover 7 and the placement seat 6;

[0032] Through the above-mentioned structural setting, the rectangular sliding plate 81 is fixed inside the movable groove 61 when the placement cover 7 and the placement seat 6 are closed, preventing the test frame 8 from rotating and affecting the placement of items. The limit groove 62 is used to limit the displacement of the test frame 8 when the placement cover 7 and the placement seat 6 are closed.

[0033] Reference Figure 2-4 , wherein the tension component 9 includes an electric telescopic rod 91, the electric telescopic rod 91 is installed inside the atomizing chamber 2, and lifting grooves 92 are opened on both the front and rear sides of the atomizing chamber 2, and the telescopic end of the electric telescopic rod 91 is connected to the placement cover 7, and the front and rear ends of the placement cover 7 are both located inside the lifting grooves 92;

[0034] Through the above-mentioned structural arrangement, the placement cover 7 is driven by the electric telescopic rod 91 to move up and down inside the lifting slot 92 to control the opening and closing of the placement cover 7 and the placement seat 6.

[0035] Working principle:

[0036] The first step to implement the innovation point:

[0037] Step 1: When preparing to conduct a salt spray test on a part, install a suitable number of test racks 8 to the corresponding positions on the placement seat 6 according to the size and shape of the part, then start the electric telescopic rod 91, and drive the placement cover 7 to move downward inside the lifting slot 92 through the electric telescopic rod 91. After the placement cover 7 and the placement seat 6 are closed, fix the rectangular sliding plate 81 inside the moving slot 61 to prevent the test rack 8 from rotating and affecting the placement of the test part. The limit slot 62 is used to limit the displacement of the test rack 8 when the placement cover 7 and the placement seat 6 are closed;

[0038] Step 2: After the fixing is completed, close the box cover 5 and inject clean water into the sealing groove 10 to improve the sealing effect of the box cover 5 and prevent the salt mist from seeping out from the gap between the box cover 5 and the box body 1. Then pour the test solution into the water injection tank 4, start the atomizing nozzle 3 to spray the atomized solution into the inside of the atomizing chamber 2, and test the parts;

[0039] Step 3: After the test is completed, wait for the internal salt spray to be cleaned, open the box cover 5, take out the parts, start the electric telescopic rod 91, and when the placement cover 7 is separated from the placement seat 6, the spring 63 is reset to push the test frame 8 out through the lifting plate 64 for workers to take and replace.
