Problems solved by technology

At present, the most commonly used sensor for feedback linear displacement is the redundancy linear displacement sensor. The axial linear displacement of the hydraulic actuator can be directly and synchronously transmitted to the redundancy linear displacement sensor, but the redundancy linear displacement sensor has a long axial length. Disadvantages, and multiple sets of coils are integrated in one sensor, which is easy to form a single point of failure, and the reliability is low. For products with multi-sensor configuration, short axial size requirements and hydraulic actuators that do not have the conditions of a built-in linear sensor in the center hole not applicable

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] The transmission structure of the four-corner displacement sensor layout is as follows: figure 1 shown. The figure shows the installation method of the four-corner displacement sensor layout transmission structure. The double-ring groove joint 2 is tightly connected with the hydraulic actuating rod 1 through the nut 6, so that the double-ring groove joint 2 can receive the linear displacement of the hydraulic actuating rod 1 synchronously. The ball head of the rocker arm 7 is put into the ring groove of the corresponding part of the double-ring groove joint 2 to ensure that the double-ring groove joint 2 can drive the rocker arm 7 to deflect after the linear displacement occurs. The other end of the rocker arm 7 is connected to the rotor of the angular displacement sensor 4 and fastened by tightening the gap with the screw one 5 to ensure that the de...

Description

technical field [0001] The invention belongs to the field of hydraulic engineering, and is a structure with four-corner displacement sensor layout and high-precision and reliable displacement feedback transmission. Background technique [0002] In the control of hydraulic servo products with multiple electrical redundancy, it is necessary to receive the displacement signal of the hydraulic actuating rod for linear displacement in each electrical redundancy channel to realize servo control. Sensor-like electrical components are usually used to complete the feedback of the displacement signal during design. At present, the most commonly used sensor for feedback linear displacement is the redundancy linear displacement sensor. The axial linear displacement of the hydraulic actuator can be directly and synchronously transmitted to the redundancy linear displacement sensor, but the redundancy linear displacement sensor has a long axial length. Disadvantages, and multiple sets of ...
