Problems solved by technology

[0003] At present, the most widely used hydraulic cylinder jacking test bench is to measure the push-pull force. By connecting the tested actuator with the jacking cylinder test device, the performance test of the tested actuator is realized by increasing or decreasing the push-pull force on the jacking cylinder. Although this structure can realize the measurement of push-pull force, this structure generally requires hydraulic components such as a separate pump station and a top cylinder. Unable to move freely without experimenting

Embodiment Construction

[0026] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] The invention provides a mobile loading test bench. The actuator is connected to the internal lugs of the test bench through corresponding structural design improvements, the thrust load is displayed through the pressure sensor, the displacement and force changes are realized by the compression and extension of the disc spring, and the adjustment nut and The disc spring can realize the adjustment of the initial installation distance and load force, and the test bench is equipped with eyebolt screws to realize the free movement of the platform and the actuator under test. This structural form is easy to disassemble and assemble, and plays an important role in verifying the performance of the actuator in a specific...

Abstract

The invention relates to a movable loading test bench, and belongs to the technical field of thrust test bench testing tools. Synchronous movement of the tested mechanism and the test bench during self-locking can be achieved, the tested mechanism can generate large reverse thrust during small extension displacement due to the large elastic coefficient of the disc spring, the whole mechanism occupies a small space, and a special environment test can be conveniently conducted on the whole executing mechanism; and the middle sliding plate can realize the adjustment of the thrust and the installation distance of the tested mechanism by adjusting the number of the locking nuts and the disc springs, so that the convenience during installation and the use diversity of the test bed are ensured.

Description

technical field [0001] The invention belongs to the technical field of thrust test bench testing tooling, and in particular relates to a mobile loading test bench. Background technique [0002] The hydraulic top test bench is a performance test device used to measure the performance of electric cylinders and hydraulic cylinders under a certain load, and plays an important role in verifying the performance of actuators such as electric cylinders and hydraulic cylinders. In order to further verify the performance of electric cylinders or hydraulic cylinders in specific environments, it is extremely important to design a small and movable loading test bench. [0003] At present, the most widely used hydraulic cylinder jacking test bench is to measure the push-pull force. By connecting the tested actuator with the jacking cylinder test device, the performance test of the tested actuator is realized by increasing or decreasing the push-pull force on the jacking cylinder. Althoug...
