Robot annular rail

The invention relates to the field of rails, in particular to a robot annular rail. The robot annular rail comprises an arc-shaped bending auxiliary guide rail, a working guide rail, two rotary guiderails, two pneumatic push rods, two baffles, two mandrels, a wire harness guide device and a fixing support; the working guide rail can be arranged in parallel to the middle section of the auxiliary guide rail; the tail ends of the two rotary guide rails are rotationally arranged on the left side and the right side of the working guide rail through the mandrels; one end of each of the two pneumatic push rods is hinged to the corresponding baffle; and an industrial robot is capable of moving in parallel, and the direction can be unchanged. Central rotary joint devices such as a control wire harness and a pipeline required by the robot are fixed above the annular rail through the support, so that when the robot circularly moves along the annular rail, the control wire harness and the pipeline are enabled to do simil
