Abstract

The invention provides an active angle driving device and a rotating coupler. The device includes a centering mechanism, which includes a housing assembly, a centering plate pivotally arranged in the shell assembly and a piston assembly pressing against the surrounding wall of the centering plate, and the centering plate is provided with a sleeve, a protrusion, The notch and the cam, the protrusion and the notch are symmetrically arranged on both sides of the cam; the guide plate assembly is connected with the shell component and the sleeve, and is provided with an arc-shaped guide groove matching the cam and the protrusion, and the protrusion Placed in the arc-shaped guide groove; a pivotally installed drive mechanism in the housing assembly, which includes a cam plate assembly provided with a bar-shaped groove and a drive shaft assembly installed in the bar-shaped groove; and connected with the drive mechanism Power components. The power assembly pushes the cam plate assembly to rotate and extrudes the piston assembly, and the drive shaft assembly moves along the guide groove. When it moves to contact with the protrusion, the centering disc is driven to rotate by continuing to move. The centering disc is connected with the mechanical structure, which can realize the automatic rotation of the mechanical structure.

Description

Technical field [0001] The present invention belongs to the technical field of rail train hook slow device, in particular to an active corner drive device and a rotating hook. Background [0002] Generally, tram and subway project hooks are equipped with alignment devices that cannot be automatically rotated, and the automatic horizontal swing of the hook cannot be realized. Prior art has disclosed hook rotation mechanism, which can realize the hook horizontal direction of any angle rotation function. When the hook is required to swing horizontally, first cut off the cylinder intake, the cylinder's reset spring makes the cylinder tappet move backwards, and at the same time drive the roller and the arc notch of the inner gear cam disc to separate, and the inner gear cam disc is in a free state. At this time, the external gear transmission mechanism is rotated by a two-way stepper motor, and the external gear transmission mechanism drives the inner gear cam disc rotation through ge...
