[0064] In this embodiment, the specific configuration of the movable component 300 is optimized. Specifically, the movable component 300 is configured as a composite component including at least a movable member 310, a second connecting member 320 and a second flexible member 330. The movable member 310 may be a flat plate structure, which is vertically arranged on one end of the track 110. The size and shape of the movable member 310 are equivalent to the size and shape of the fixed member 210. The second connecting member 320 may be a protruding connecting block structure, which is horizontally arranged on the movable member 310.

[0065] See also Figures 1 to 4 In a possible implementation, the movable component 300 further includes a second reinforcing rib 340 that is movably disposed. The second reinforcing rib 340 is disposed between the movable part 310 and the working platform 100 , and the second reinforcing rib 340 is located on a side of the movable part 310 away from the fixed component 200 .

[0066] In this embodiment, the specific configuration of the movable component 300 is further optimized. Specifically, the movable component 300 is configured as a composite component including at least a movable part 310, a second connecting part 320, a second flexible part 330 and a second reinforcing rib 340.

The drive component 700 can be a hydraulic cylinder component, which is used to provide driving force to the movable component 300, realize the intelligent drive of the movable component 300, and facilitate operation. Specifically, when the control component 600 receives a real-time tension value less than a preset tension value, it controls the drive component 700 to drive the movable component 300 to move in a direction away from the fixed component 200, so as to gradually increase the external tension to the workpiece 10 to be tested; after the control component 600 receives a real-time tension value equal to or greater than the preset tension value, it first controls the drive component 700 to stop working, so as to prevent the movable component 300 from continuing to move in a direction away from the fixed component 200 and causing excessive testing, thereby improving the reliability of the test results, and then controls the drive component 700 to move in reverse to reset the movable component 300.

The detection component 500 obtains the tension value and transmits the tension information to the control component 600. The control component 600 receives the tension information and compares the tension information with the preset tension value. When the test requirements are met, the hydraulic station 720 is stopped immediately, and the hydraulic cylinder 710 is no longer filled with fluid and pressurized to complete the pressurization test; then, pressure relief, resetting of the test device and other processes are performed according to relevant test requirements to complete the test operation.

[0073] In this embodiment, the specific configuration of the test bench is further optimized.

At this time, the detection component detects the pressure in the hydraulic cylinder 20 to be tested and transmits the pressure information to the control component 600; the control component 600 receives the pressure information, and compares the pressure information with the preset pressure value. When the real-time pressure value is greater than or equal to the preset pressure value, the pressure-applying component 900 stops working. At this time, it is determined whether there are cracks, crushing injuries and other damages on the hydraulic cylinder 20 to be tested. If not, the hydraulic cylinder 20 to be tested is judged to be qualified; if so, the hydraulic cylinder 20 to be tested is judged to be unqualified.
