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.

Abstract: A normally closed disc clamp system includes a housing with a rotating disc, a brake ring and a pressure-enhancing ring arranged therein. When only a first chamber is supplied with fluid, the fluid pushes the brake ring to release the rotating disc. When only a second chamber is fed with fluid, the fluid pushes the brake ring to keep the rotating disc in the braking state, and pushes the pressure-enhancing ring to compress an elastic unit. The energy generated by the compression of the elastic unit acts on the brake ring through the fluid, so that the brake ring achieves a double pressurization effect. If the action of the fluid fails, the brake ring can still provide a braking effect to the rotating disc through the elastic unit to improve operational safety. Further, the present invention further provides a rotating table using the normally closed disc clamp system.

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 pushing force-actuated braking device includes an annular housing that houses a brake disc, a braking piston, plural braking elements, and a brake-releasing piston. When only the braking piston is under the action of a fluid, the braking piston applies an axial pushing force to the brake disc such that the brake disc is kept at a braking position jointly by the braking piston and the braking elements. When only the brake-releasing piston is under the action of a fluid, the brake-releasing piston applies an opposite pushing force to the brake disc to keep it at a brake-releasing position. Should the fluid acting on the braking piston fail, the force of the braking elements still enables the brake disc to produce a braking effect. The pushing force-actuated braking device has a modular design to facilitate assembly and disassembly. A rotary table using the braking device is also provided.
