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 retainer is used for a linear guideway, including a main body, a retaining portion, and a hollow portion. The main body extends along the longitudinal direction of the retainer. The retaining portion extends from a long side of the main body along the width direction of the retaining portion. The hollow portion is abutted between the retaining portion and the main body for allowing a part of the retaining portion to be elastically deformed when the retaining portion is compressed by an external force. Therefore, when balls are assembled, the retainer of the present invention uses the partial elastic deformation of the retaining portion to avoid damage caused by directly collided with the balls, thereby enhancing convenience of installing and removing the balls. In addition, the hollow portion can be used to save lubricating oil for achieving the effect of extended lubrication.

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 seat including a base includes an outer surface, and a composite material layer attached to at least a part of the outer surface. The base also includes a recess for accommodating a turntable and including a first opening on the outer surface. The material of the composite material layer includes fibers and a resin. Therefore, the rotary seat may be more lightweight. A rotary table is also provided and includes the rotary seat, a driving device which drives the rotary seat to rotate, and a turntable which is rotatably disposed in the recess of the base.

Abstract: A miniature linear guideway includes a rail, a slider, two circulation fittings and a retainer. The slider and the circulation fitting are set on the rail, so that a circulation channel is formed between the rail and the slider for the balls to run. The circulation fitting has several turning convex portions. The retainer has a plate portion and two retaining portions. The two ends of each retaining portion are connected to the plate portion by a positioning portion, and the plate portion is adjacent to the slider. The positioning portions of the retainer abut the turning convex portions. The width of the plate portion of the retainer is smaller than the distance between the turning convex portions of the circulation fitting. Thereby, the miniature linear guideway of the present invention can optimize the assembly efficiency, thereby realizing the purpose of automatic assembly.

Abstract: A gripper device includes a base and two gripping assemblies, each including a gripping member, a stand, and an elastic member. The gripping member includes a gripping portion and a supporting portion. The stand is movably disposed to the base and includes a connecter and a supporter. The supporting portion is pivotally connected to the supporter at a position between the gripping portion and the connecter so that the gripping member is pivotable relative to the stand. Two opposite ends of the elastic member are respectively connected to the supporting portion and the connecter. When one of the gripping portions touches an object, the gripping member pivots relative to the corresponding stand. Therefore, gripping a target may not be interrupted by interference objects around the target.
