The second balance rod 27 is rotationally connected to the surfaces of the second clamping block 28 and the fixed block 2. The placement platform 13 is abutted and connected to the surfaces of the first clamping block 25 and the second clamping block 28.

The two cooperate to clamp and fix the cylinder piston 14 on the surface of the placement platform 13.

[0034] Further, the fixed shafts 3 are symmetrically distributed in two groups on the surface of the press 12. With the arrangement of the two groups of fixed shafts 3, two protective covers 32 are rotatably connected thereto, which are used to protect the tablets on the surface of the press 12. The two ends of the torsion spring 31 are fixedly connected to the surface of the fixed shaft 3 and the inside of the protective cover 32. The arrangement of the torsion spring 31 enables the two protective covers 32 to abut against each other. The protective cover 32 is rotatably connected to the surface of the press 12 through the fixed shaft 3. Rotating the protective cover 32 can open the protective cover 32 so as to use the press 12.

[0035] Further, the connecting blocks 33 are symmetrically distributed in two groups on the surface of the press 12.

The limiting plates 35 are abutted and connected to the surface of the protective cover 32 through the limiting blocks 34. The protective cover 32 is fixedly connected to the surface of the press 12 through the limiting plates 35. After the protective cover 32 is rotated and opened, the torsion spring 31 is deformed. The limiting plate 35 can be rotated so that the limiting plate 35 acts on the surface of the protective cover 32 to limit the position of the protective cover 32. The protective cover 32 is rotatably connected to the surface of the press 12 through the torsion spring 31. When the limiting plate 35 is rotated away from the surface of the protective cover 32, the torsion spring 31 drives the protective cover 32 to reset to its original state.

[0036] Working principle: When using the detection platform 1, first place the cylinder piston 14 to be subjected to strength detection on the placement platform 13, and then start the air cylinder 21 to drive the active rack 22 to move, thereby driving the first driven rack 23 and the second driven rack 26 to rotate, and further enabling the first clamping block 25 and the second clamping block 28 to move on the surface of the placement platform 13 to clamp the cylinder piston 14, thereby fixing the position of the cylinder piston 14 on the surface of the placement platform 13. The settings of the first balance bar 24 and the second balance bar 27 ensure that the first clamping block 25 and the second clamping block 28 always move horizontally. Then, rotate and open the protective cover 32. The torsion spring 31 is deformed. Rotate the limiting plate 35 below the protective cover 32 to release the restriction on the protective cover 32. The torsion spring 31 drives the protective cover 32 to abut against the surface of the limiting plate 35, thereby fixing the opened position of the protective cover 32. Then, the controller 11 can be started to control the use of the press 12. The press 12 presses on the surface of the cylinder piston 14 through the moving tablet to perform a pressure test. The test data is fed back to the controller 11. After the test, rotate the limiting plate 35 so that the limiting plate 35 leaves the surface of the protective cover 32. The torsion spring 31 drives the protective cover 32 to reset to its original state to protect the tablet on the surface of the press 12. Start the air cylinder 21 to make the first clamping block 25 and the second clamping block 28 leave the surface of the cylinder piston 14, cancel the clamping and fixing of the cylinder piston 14, and then take out the cylinder piston 14.
