Description

Performance test mechanism for actuator Technical Field The utility model belongs to the technical field of performance detection of hydraulic mechanisms, and particularly relates to an actuator performance test mechanism. Background In the field of hydraulic mechanism performance detection, conventional test equipment is generally designed for a specific assembly specification or connection mode, and has significant limitations. In the prior art, the performance test mechanism of the actuator mostly adopts a single detection mechanism, and the structure of the performance test mechanism is only suitable for a single connection form (such as only supporting hinged connection or only supporting fixed connection), so that the test application range is severely limited. For example, a test device designed for an articulated single-cylinder hydraulic mechanism cannot be compatible with the test requirement of a multi-cylinder hydraulic mechanism requiring rigid fixation by an articulated detection assembly, whereas a test device designed for fixed connection is difficult to simulate the dynamic working condition of the articulated mechanism. In addition, the single detection mechanism has limited load capacity, is difficult to cover from a low-pressure normal working condition to a high-pressure heavy-load working condition, and needs to be additionally provided with detection equipment for performance verification of a high-pressure hydraulic mechanism (such as a master cylinder of engineering machinery, a three-cylinder hydraulic mechanism and the like), so that equipment cost is increased. In a word, the limitation design of the existing detection equipment forces the detection party to configure a plurality of sets of test equipment to meet the test requirements of different hydraulic mechanisms, so that the equipment cost and the occupied area are greatly increased, and the problem that the performance data standards are not uniform due to the difference of the test platforms is easily caused.
