Rams horizontal test bench

Abstract

The application discloses an oil cylinder horizontal test bench and belongs to the technical field of oil cylinder testing. The oil cylinder horizontal test bench comprises a test frame, a mounting plate and a lifting assembly. The test frame comprises a bottom plate, a vertical plate and a top plate. A sliding groove is formed in the vertical plate in the vertical direction. The mounting plate is mounted on the vertical plate through the sliding groove. A calibration hole is formed in the mounting plate. The calibration hole is provided with a plurality of types of fixing plates. The fixing plates can be rotated and calibrated in the calibration hole under stress. The output end of an oil cylinder to be tested is connected with the fixing plates. One end of the lifting assembly is connected with the mounting plate. The other end of the lifting assembly is connected with a hand wheel. The hand wheel is rotated to drive the mounting plate to move up and down. The application has the advantages of simple overall structure, high flexibility and convenient operation.
