The invention discloses a tensioning device of a cylinder driving synchronous belt. The tensioning device comprises a synchronous belt frame, wherein a linear guide rail is fixedly arranged on the inner wall of the synchronous belt frame; a sliding rail of the linear guide rail is connected with a sliding seat in a sliding manner; a synchronous belt driving wheel is fixedly arranged on the surface of the sliding seat; the side of the bottom end of the sliding seat is hinged with one end of a first connection rod through a first rotating shaft; the other end of the first connection rod is rotatably connected with the tail end of a second connection rod and the top end of a cylinder piston rod through a third rotating shaft respectively; and the cylinder piston rod is arranged in a cylinder. The tensioning device of the cylinder driving synchronous belt has the beneficial effects that a polyurethane limiting block is additionally arranged behind the sliding seat to serve as mechanical hard limiting, the movement distance of the cylinder piston rod is indirectly controlled, a cylinder driving connection rod can serve as a force increasing mechanism, and the tensioning state of the synchronous belt can be rapidly controlled.
Description
technical field [0001] The invention relates to a synchronous belt tensioning device, in particular to a tensioning device for a cylinder-driven synchronous belt, and belongs to the technical field of synchronous belt tensioning. Background technique [0002] Synchronous belt transmission is widely used in various production and processing fields of enterprises. However, in some working conditions, the synchronous belt needs to be in a loose state, and the commonly used mechanical adjustment device cannot achieve this effect. In order to realize the automatic control of the tension of the synchronous belt The purpose is to use the cylinder to drive the pulley to control the tension of the timing belt, but there is a problem with the cylinder drive. The cylinder is the actuator and cannot control the movement distance of the cylinder piston rod within the stroke, so an adjustable polyurethane limit block is added behind the slide seat as a The mechanical hard limiter indirect...
