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.

Abstract: A brush module for a rotary table includes: a housing, a brush unit, a first pushing unit and a second pushing unit, the brush unit includes a brush disposed in the housing, a conductive wire electrically connected to the brush, and a pushing force for pushing the brush towards the opening of the housing. The first and second pushing units oppositely provided on the housing provide the brush a first and a second pushing forces in opposite directions to resist the lateral thrust generated by friction between the brush and the rotary disk of the rotary table, thereby greatly reducing the vibration, shaking, slipping, line contact and other conditions of the brush caused by high-speed rotation of the rotary disk, avoiding damaging the peripheral surface of the rotary disk, and maintaining good electrical contact between the brush and the rotary disk.
