The invention relates to a high-precision, easily-assembled and easily-disassembled steering surface connection structure which is arranged on an electric steering engine. The connection structure comprises a steering shaft and a steering fork. One end of the steering shaft is connected with a steering engine
rocker arm, and the other end of the steering shaft is provided with a steering shaft
flange surface; one end of the steering fork is of a fork-shaped structure and is connected with a steering surface, the other end of the steering fork is provided with a steering fork
flange surface; and the steering fork
flange surface and the steering shaft flange surface are connected through a clamping groove and are firmly mounted through a fixing
assembly, so that the steering engine
rocker arm, the steering shaft, the steering fork and the steering surface are connected to be a whole. When the electric steering engine receives an instruction to drive the steering engine
rocker arm to rotate, the steering shaft and the steering fork drive the steering surface to achieve deflection to complete predetermined actions. According to the steering surface connection structure, the disassembling and assembling process is easy to operate, the
assembly manufacturability is good, the size is small, positioning precision is high, connection reliability is high, and the steering surface connection structure is suitable for connection between the electric steering engine which is small in size and large in load and the steering surface.
