Embodiment
[0060] A kind of hydraulic variable stroke can be fine-tuned positioning locking type hydraulic cylinder test bench according to the embodiment of the present invention is as follows: figure 1 , figure 2 , image 3 As shown, the hydraulic cylinder test bench adopts a frame structure composed of casting plates and optical axes. The distance between the tested hydraulic cylinder mounting plate and the loading hydraulic cylinder mounting plate is realized by the two positioning hydraulic cylinders and the hydraulic control system installed on it. Adjustable for test versatility with this bench.
[0061] In this embodiment, the front plate (2) and the rear plate (11) are fixed on both ends of the optical axis (3) by lock nuts (17), and the middle plate (7) and the guide support plate (4) are installed on the front plate (2) and the rear plate (11), and can slide freely on the optical axis (3), two positioning hydraulic cylinders (9) are installed on the rear plate (11), and its...
