Abstract
The invention discloses a mechanical rotary drawing mechanism and belongs to the technical field of the machine design. The mechanical rotary drawing mechanism comprises a control body, an eccentric shaft, eccentric cavities, eccentric bodies, eccentric springs, arc plates, an elastic band and extension springs. One end of an extension bar penetrates through the upper wall face of an adjusting body and is fixedly combined with the upper wall face of a movable body. The eccentric cavities, the eccentric bodies, the eccentric springs, the arc plates and the elastic band are all arranged in the control body. One ends of the eccentric bodies are arranged in the eccentric cavities and connected with the eccentric shaft through the eccentric springs, and the other ends of the eccentric bodies are of an arc structure and make contact with the arc plates in a sealed mode. The elastic band is arranged on the outer surfaces of the arc plates. When the rotation speed of an engine is high, the movable body moves upwards, and the necking rate of an exhaust manifold is increased; when the rotation speed of the engine is low, the movable body moves downwards, and the necking rate of the exhaust manifold is decreased. The mechanical rotary drawing mechanism is reasonable in design, simple in structure, and suitable for the optimal design of the exhaust pipe volume of a turbine pressurization system.
