Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder testing equipment, in particular to an oil cylinder testing bracket. Background Art

[0002] After the hydraulic cylinder is assembled, it is usually necessary to conduct factory tests to check its performance. However, the strength assessment of the various components and welds of the cylinder, especially the strength assessment of the piston rod component, cannot be met by general factory tests, which requires an external loading test on the cylinder. Now; Another problem is that in the test of the internal leakage value of the cylinder top loading detection, the data of the leakage value of the tested cylinder is inaccurate due to the influence of the internal leakage of the loading cylinder itself. The more conventional loading method of the existing cylinder test bench is to load the cylinder and the tested cylinder top to top. The disadvantage of this method is that the manufacturing cost of the cylinder is relatively high, and the full stroke test cannot be performed for some long-stroke cylinders, and the test stability cannot be guaranteed, which is easy to affect the test accuracy. In addition, when testing hydraulic cylinders with eccentric loads, the test process is not smooth enough. To this end, we propose a cylinder test bracket. Utility Model Content
