Zusammenfassung:The invention discloses a parallel mechanism with two degrees of freedom. The mechanism comprises an operating deck, a driving motor, a guide rail, guide sleeves, sliding blocks and synchronous belts, wherein two reversing shaft sleeves are respectively mounted on the two sliding blocks and serve as upper-lower two layered guide sleeve structures; driving sleeves are mounted at the other ends corresponding to belt pulleys, on the two sides of the operating platform in the Y direction; synchronous belts are respectively connected with the both ends of a working sliding blocks; each synchronous belt sequentially bypasses the reversing shaft sleeves, the belt pulleys, the driving sleeves, the driving sleeves on the different sides, and the reversing shaft sleeves on the different sides from one end of the working sliding block, and then is fixed at the other end of the working sliding block; the first synchronous belt and the second synchronous belt are mounted on different horizontal planes. The single reversing shaft sleeves with the upper-lower guide sleeve structures are used to substitute the existing two reversing shaft sleeves, so as to improve the layout of the synchronous belts in the parallel mechanism, and greatly increase the occupancy of the X-Y driving platform in a work space.
