Mechanical displacement coupling and decoupling mechanism

Abstract

The invention provides a mechanical displacement coupling and decoupling mechanism. In the mechanism, an input slideway is in a groove shape, an input point is fixed to the side edge of the input slideway, two sets of side rails are arranged on the two sides of the input slideway, and the input slideway can linearly move along the side rails. A first input rod is parallel to the two sets of side rails, a rod body penetrates in a casing pipe of a cross-shaped sleeve, one end of the first input rod is arranged in cooperation with the input slideway and can slide along the input slideway, and the other end of the first input rod is hinged to a first middle connecting rod and a second middle connecting rod. The other end of the first middle connecting rod is hinged to a first output rod, and the other end of the second middle connecting rod is hinged to a second output rod. The other two ends of the cross-shaped sleeve are arranged on core rails in a sleeving manner respectively and can horizontally move along the core rails, the first output rod and the second output rod penetrate two output pipe rails respectively and can horizontally move along the output pipe rails, and a second input rod penetrates an input pipe rail and is fixedly connected with a cross-shaped pipe rail. The motion direction of the first input rod is always perpendicular to that of the second input rod, and the input pipe rail, the core rails, the output pipe rails and the side rails are all fixed rails. The mechanism is simple in principle, clear in work process, easy to implement and precise in design.

Description

technical field [0001] The present disclosure relates to mechanism design in the field of mechanical design, in particular to a mechanical displacement coupling and decoupling mechanism. Background technique [0002] In the current field of mechanical design, the traditional mechanism is considered to be the easiest to use and also the most reliable and safe mechanism. Especially for the mechanism of connecting rods, the elements of the connecting parts of each unit have incomparable advantages in terms of manufacturing accuracy and manufacturing cost. The link mechanism is generally used in mechanical transmission, especially in planar or spatial bar system motion mechanisms, and is widely used as mechanical displacement transmission. It is generally a single-input or single-output type, that is to say, one input point corresponds to multiple output points, or multiple input points correspond to one output point. [0003] However, it is difficult to implement the link mec...

Problems solved by technology

[0004] For the mechanical displacement coupling and decoupling of the dual-input and dual-output type, there are many problems: 1. The mutual interference between the two inputs. For the multi-input and single-output mechanism, generally between multiple input points There will be forces, mutual constraints, and disputes will appear; 2. The linear superposition problem between the outputs. Between the two output terminals, it is necessary to strictly control the output displacements corresponding to each input signal to be linearly superimposed and not affect each other. of
