Abstract
The utility model relates to an asymmetric large-stroke tensioning device, which comprises a centering seat, an upper piston hole, a lower piston hole and centering chutes, the lower piston hole is positioned below the upper piston hole, and the centering chutes are arranged in an annular array manner; the centering piston is movably arranged in the upper piston hole and provided with pushing sliding grooves which are obliquely formed, and the pushing sliding grooves are formed in an annular array mode and correspond to the centering sliding grooves in a one-to-one mode; the reset piston is movably arranged in the lower piston hole and is connected with the centering piston; the tensioning rod is provided with a pushing sliding block, the tensioning rod is arranged in the centering sliding groove in a sliding mode, and the pushing sliding block is inserted in the pushing sliding groove in a sliding mode; the centering piston is used for driving the reset piston to move towards the top of the centering base, and the pushing sliding groove pushes the tensioning rod to stretch out synchronously. The reset piston is used for driving the centering piston to move towards the bottom of the centering base so that the pushing sliding groove can push the tensioning rod to retract synchronously. According to the asymmetric large-stroke tensioning device, large-stroke centering and tensioning are achieved through the tensioning rod which is eccentrically arranged and can stretch out and draw back, and the asymmetric large-stroke tensioning device is simple in structure and low in cost.
