Actuator cylinder intelligent test system

Abstract

The invention discloses an actuator cylinder intelligent test system, which comprises an actuator cylinder fixing seat, a dial-turn mechanism, a torque sensor, a coupling, a jaw clutch, a harmonic gear reducer, a motor, a support and a table board. According to the actuator cylinder intelligent test system, the test bench is vertically arranged to test a product, the additional torque of the connecting plate in the turning mechanism to the actuating cylinder of the product due to the dead weight can be avoided; as the mounting surface of the table surface of the test table is independently processed and is provided with the key slots, and the supports mounted on the table surface are also provided with the key slots, the requirements of mounting flatness and coaxiality are ensured, and the mounting is convenient for workers; and the torque sensor is installed close to one side of the product, and the measured torque value of the actuator cylinder of the product is accurate due to the fact that the additional friction torque value generated in the middle transmission link is reduced. Whether the movable end and the fixed end of the jaw clutch are meshed or not is judged by installing the distance sensor, and it can be guaranteed that the tooth sliding phenomenon cannot be generated in the torque transmission process.

Description

technical field [0001] The invention relates to the technical field of performance testing of actuators, in particular to an intelligent testing system for actuators. Background technique [0002] This kind of actuator is the main part of the landing gear of the aircraft, and a torsion spring is installed inside it (the torsion spring is connected with the external lever), and the hydraulic oil is loaded through the oil nozzle to realize the torque applied to the torsion spring, thereby realizing energy storage effect. [0003] At present, there are certain shortcomings in the testing device test bench for testing the relationship between the angle of rotation of the actuator lever (torsion spring) and the torque: [0004] 1) The test bench is placed horizontally, and the dial mechanism will generate additional gravity torque on the actuator; [0005] 2) The torque sensor is far away from the product actuator, and the measured actuator torque contains the transmission fric...

Problems solved by technology

[0006] 3) The table top of the test bench and the support are welded together, and it is impossible to directly process the table top. When installing each support, copper pads and additionally processed mandrels are required for installation, so as to ensure the coaxiality requirements. Since it is a multi-stage installation, It not only increases the labor intensity of workers, but also makes it difficult to ensure the coaxial requirements of each support;

[0007] 4) The test bench uses a friction plate jaw clutch, and slipping will occur when a large torque is transmitted
