The invention relates to an airplane rotary joint durability test bench, and belongs to a test device for testing durability of a rotary joint. The invention relates to an airplane rotary joint durability test bench. The test bench comprises a bench main body, a power mechanism, a rotation limiting mechanism and a signal feedback mechanism, the fixed end of the rotary joint is mounted on the rack main body, and the rotary end is connected with the rotary limiting mechanism; the power mechanism is arranged on the rack main body and is used for providing power for the rotation of the rotary limiting mechanism; the rotation limiting mechanism is matched with the signal feedback mechanism to limit the rotation angle; when the rotation limiting mechanism rotates to a set angle, the signal feedback mechanism feeds back a signal to the PLC, and then the PLC controls the power mechanism to stop and rotate reversely. The device has the following advantages: 1, the durability of the aircraft rotary joint can be tested; 2, different rotary joints can be installed for testing; 3, the limiting mechanism prevents rotation over-limit through a proximity switch and can be freely adjusted; and 4, the device is convenient to move and applicable to different places.
本发明涉及一种飞机旋转接头耐久试验台,属于测试旋转接头耐久性能的试验装置。一种飞机旋转接头耐久试验台,所述试验台包括台架主体、动力机构、旋转限位机构和信号反馈机构;旋转接头的固定端安装在台架主体上,旋转端与旋转限位机构连接;动力机构设置在台架主体上,用于为旋转限位机构转动提供动力;旋转限位机构配合信号反馈机构对其旋转角度进行限位;当旋转限位机构旋转到设定角度,信号反馈机构反馈信号给PLC,进而PLC控制动力机构停止及反转。本发明具有如下优点:1、可以测试飞机旋转接头耐久性能;2、可安装不同的旋转接头进行试验;3、限位机构通过接近开关防止旋转超限,可自由调节;4、移动方便,可适用不同场所。
