Undercarriage automatic return-to-center test device

Abstract

The invention provides an undercarriage automatic return-to-center test device. The device includes an electrical box assembly, a display panel assembly, guide blocks, a position sleeve assembly, a latch, clamping grippers, a chuck assembly, a first transmission assembly, a second transmission assembly and a large pedestal; the position sleeve assembly and the guide blocks are used for supportinga test object; the latch is used to connect the test object and plays a role of limitation; the clamping grippers are used for tightly grasping the test object and fixedly connected to the chuck assembly; and the chuck assembly receives the torque jointly transmitted by the first transmission assembly and the second transmission assembly so that the chuck assembly can be driven to perform torsionin a positive direction or a negative direction. According to the embodiments, the device is laborsaving in operation and convenient; torsion can be accurately realized by only arranging rotation angles and forward and reverse buttons on a display screen, so that efficiency can be enhanced, the quality consistency of products can be guaranteed, and the purposes of digital control and accurate rotational moment value collection can be achieved.

Description

technical field [0001] The invention relates to the technical field of assembly test and adjustment control technology of aviation landing gear, in particular to a test device used for mid-cycle test of each aircraft landing gear. Background technique [0002] In order to simulate the turning of the wheels after the landing gear is installed, the flexibility of returning to the neutral position, and intuitively reflect whether the cam rotation state is normal, it is necessary to perform a functional inspection of the centering test in the landing gear assembly stage in advance. However, the existing centering test uses simple positioning fixtures to install and fix the landing gear, and relies on the cooperation of two people to complete the inspection of the torsional angle and torque. The starting torque is measured by manual pulling of the spring scale. The test is very irregular and the data is inaccurate. Contents of the invention [0003] In view of this, in order t...
