Oil cylinder test device and method

Abstract

The invention provides an oil cylinder test device and method, and belongs to the technical field of mechanical equipment. A to-be-tested oil cylinder is placed on a supporting table, a pushing cylinder completely pushes a to-be-tested piston rod of the to-be-tested oil cylinder back into the to-be-tested oil cylinder, and the to-be-tested oil cylinder stores pressure; the internal pressure of the to-be-tested oil cylinder is released, then the to-be-tested piston rod is pushed out, and a connecting shaft and a collision plate in a limiting assembly move along with the to-be-tested piston rod; and the first limiting face of the collision plate has areas on the two radial sides of the to-be-tested oil cylinder, at least two anti-collision shock absorbers distributed on the two radial sides of the pushing cylinder are arranged on the supporting table, compression rods of the anti-collision shock absorbers directly face the first limiting face, the compression rods extend out of check blocks, and each check block is provided with a second limiting face parallel to the first limiting face. According to the oil cylinder test device and method, the collision plate and the check blocks limit the position of the to-be-tested piston rod, the accurate maximum stroke of the to-be-tested oil cylinder is obtained, and the movement time is obtained through testing; and the obtained parameters of the stroke and duration of theto-be-tested oil cylinder are accurate, so that the working performance of theto-be-tested oil cylinder can be accurately judged.

Description

technical field [0001] The disclosure relates to the technical field of mechanical equipment, and in particular to an oil cylinder test device and test method. Background technique [0002] An oil cylinder is a common mechanical device for driving. The oil cylinder at least includes a cylinder base and a piston rod, and the piston rod is slidably inserted in the cylinder base. After the oil cylinder is prepared, in order to ensure that the oil cylinder can realize normal piston drive, the stroke of the piston rod of the oil cylinder will be tested. [0003] At present, when testing the stroke of the piston rod of the oil cylinder, it is usually released after the piston rod of the oil cylinder is controlled to shrink to the maximum extent, and then the piston rod moves to the maximum stroke of the piston rod. However, the piston rod of the oil cylinder is easily affected by external factors such as impurities during the movement process, resulting in the displacement of the...

Problems solved by technology

However, the piston rod of the oil cylinder is easily affected by external factors such as impurities during the movement process, resulting in the displacement of the piston rod, or the measurement of the piston rod is not accurate enough, resulting in the inaccurate parameters of the stroke of the piston rod that reflect the performance of the oil cylinder, which is difficult to obtain. Effectively judge the working performance of the cylinder
