Abstract: A rotary table includes a housing having a first groove, a second groove and a drainage channel connecting the first groove and the second groove, a motor, a shaft located in the housing and provided with a guide portion, and a leak detection belt set in an accommodation chamber in the housing and embedded in the second groove. In this way, if liquid enters the housing, the guide portion of the shaft guides the liquid into the first groove, so that the liquid reaches the second groove along the drainage channel. At this time, the leak detection belt can be used for leakage detection to protect key components.
