Abstract

The invention discloses a novel lifting cylinder. The novel lifting cylinder comprises a cylinder body (2) with a first inner cavity (1), a piston (4) which is arranged inside the cylinder body (2) and can slide along the inner wall of the cylinder body (2), and a base (6) which is connected to the first end of the cylinder body (2) and can input gas to the cylinder body (2). The piston (4) is further fixedly connected with a piston rod (8) which penetrates through the second end of the cylinder body (2). The piston rod (8) is connected with the second end of the cylinder body (2) in a dynamic sealing mode. The novel lifting cylinder achieves fast gas advance and retreat, and can provide larger energy, hoist the height and increase the frequency for an impact test stand when being applied to the field of impact and collision tests.

Description

technical field [0001] The invention relates to a novel lift cylinder. Background technique [0002] The impact test bench is a machine used in the laboratory to simulate the ability of the product to withstand impact damage in actual use. The impact test bench is used to evaluate the adaptability of the product to the impact environment, and then the structural strength of the product is optimized through the test data to correctly evaluate the product. Shock resistance can effectively improve the reliability of product use. [0003] The impact test benches in the prior art usually use mechanical mechanisms such as cams or hydraulic lifts to realize lifting, and cannot perform high-energy, two-way impact tests. [0004] For this reason, it is urgent to provide a kind of impact test equipment with large impact energy and faster impact frequency, and the most important and critical equipment in the impact device is the cylinder. Contents of the invention [0005] The obje...
