[0038] Since the sizes of the clamps required by different manufacturers are inconsistent according to different production requirements, when the size of the test clamp changes, the installation rod needs to be frequently replaced, the above operation not only increases the test cost, but also increases the time required for the test, thereby causing the problem of low test efficiency.

[0039] In order to solve the above problems, the present application uses the following: when the clamp needs to be tested by salt spray, the clamp can be fixedly placed on the diameter expansion plate 35, then the pump 41 is turned on, the pump 41 draws salt water from the salt water tank and delivers the salt water to the inside of the spray frame 43 through the hose 42, and finally the salt water is converted into spray by the spray frame 43 and sprayed onto the surface of the clamp, at the same time, the motor 5 can be turned on, the motor 5 drives the shell 3 to rotate, the shell 3 drives the clamp on the diameter expansion plate 35 to rotate synchronously, so that the clamp can be tested by changing the surface, when the height of the spray frame 43 needs to be adjusted, the electric cylinder 44 can be turned on, the electric cylinder 44 drives the spray frame 43 to slide in the support frame 2, so that the spray frame 43 can be adjusted to the appropriate height according to the requirements, so that the corrosion condition of the clamp in the actual use process can be simulated;

[0040] When the size of the clamp changes, the first gear 32 can be driven to rotate, the first gear 32 drives the spiral groove 321 to rotate, the spiral groove 321 extrudes one end of the diameter expansion plate 35, so that one end of the diameter expansion plate 35 is synchronous sliding on the surface of the shell 3 and inside the support plate 22, when the diameter expansion plate 35 and the inner wall of the clamp are fitted, the rotation of the first gear 32 is stopped, that is, the supporting and fixing operation after the size of the clamp changes is completed.

[0048] Specifically, after the test is completed, the user needs to remove the tested clamp from the expansion plate 35. During removal, the bolts need to be turned to open the clamp, and then the clamp can be removed from the expansion plate 35. Due to the salt spray, some clamp surfaces rust. When the bolts are rusted, the disassembly becomes more difficult for the staff, resulting in longer disassembly time and a decrease in testing efficiency.

[0049] In order to solve the above technical problems, the device is used as follows: when it is needed to disassemble the completed test clamps, the rotating rod 31 is driven to drive the first gear 32 to reset and rotate, so that the first gear 32 drives the spiral groove 321 to rotate, the expansion plate 35 slides inside the supporting plate 22 and the limiting plate 33, one end of the expansion plate 35 penetrates the inside of the sliding block 331 and the limiting plate 33, and is attached to one side of the limiting block 34, and at this time the roller 343 is in the annular segment 312 of the surface limiting groove 311 of the rotating rod 31, the limiting block 34 limits the limiting plate 33, when the expansion plate 35 moves to the interface between the spiral groove 321 and the annular groove 322, the roller 343 is at the interface between the annular segment 312 and the spiral segment 313, one end of the expansion plate 35 is at the positioning groove 344 of the limiting block 34, and one end of the expansion plate 35 is limited by the magnetic rod 341, then the rotating rod 31 is driven to drive the first gear 32 to rotate, so that one side of the expansion plate 35 slides in the annular groove 322, the roller 343 slides in the spiral segment 313, so that the magnetic rod 341 slides in the positioning groove 344 under the thrust of the first spring 342, when the expansion plate 35 moves to the final segment of the annular groove 322, the roller 343 is in the final segment of the spiral segment 313, the magnetic rod 341 slides out of the positioning groove 344, and one end of the expansion plate 35 slides in the positioning groove 344 under the thrust of the second spring 351, the expansion plate 35 slides to one side of the shell, its one end is separated from the inside of the supporting plate 22, so that there is a disassembly space between one end of the expansion plate 35 and the supporting plate 22, at the same time the magnetic rod 341 moves to the outside of the shell and pushes the magnetic frame 345 to move, the magnetic frame 345 drives the pulley 346 to slide in the inclined groove 211 inside the supporting block 21, so that the supporting block 21 slides upward in the supporting frame 2 and supports the expansion plate 35, then the user can disassemble or install the clamps from the disassembly area, when it is needed to fix clamps of different sizes again, the rotating rod 31 is driven to rotate, so that the spiral segment 313 and the annular groove 322 rotate, the spiral segment 313 drives the roller 343 to move, the roller 343 drives the magnetic rod 341 to reset, the magnetic rod 341 drives the magnetic frame 345 to reset, the magnetic rod 341 drives the expansion plate 35 to separate from the positioning groove 344, then one side of the expansion plate 35 is attached to one side of the limiting block 34, at this time one end of the expansion plate 35 is at the interface between the spiral groove 321 and the annular groove 322, and the subsequent size change can be completed.

[0050] The device can drive the expansion plate 35 to slide transversely by rotating the rotating rod 31 and the first gear 32, so that the connection between the expansion plate 35 and the supporting plate 22 is cancelled and there is a disassembly space, which can conveniently and quickly install and disassemble the clamps for the user without twisting the bolts, reduces the operation strength of the workers, and improves the test efficiency.
