Problems solved by technology

Therefore, for hydraulic cylinders of different specifications, different supports need to be processed, and many support mounting holes are processed on the base, and the processed holes will inevitably have deviations, so it is difficult to ensure the concentricity of the hydraulic cylinder installed on the support; The structure is suitable for the installation of earring hydraulic cylinders, and has certain limitations for the installation of hydraulic cylinders of other structures
[0006] (3) The dovetail groove base platform is adopted, and the support, guide trolley and other accessory structures are installed on it. The principle is similar to the structure of (2) above. The difference is that there is no need to process the support mounting holes on the base, which can ensure the concentricity of the hydraulic cylinder. However, this structure also needs to process different supports. At the same time, the bolts need to be manually tightened when fixing the support. This type of support has a small bearing capacity and is not suitable for the installation and testing of hydraulic cylinders with high pressure and large cylinder diameter.
[0007] In short, at present, most hydraulic cylinder test benches are designed for hydraulic cylinders of a certain specification, and the scope of application is limited; although some are designed for hydraulic cylinders of various specifications, the installation and operation are inconvenient and the bearing capacity is limited. Small size, low production test efficiency, and hydraulic cylinders of different specifications are tested on different test benches, which leads to low equipment utilization and waste of test resources

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...
