Variable four-bar linkage swing mechanism

Abstract

The invention provides a variable four-bar linkage swing mechanism. One end of a column is hinged to a base, one end of a swing rod is hinged to one end of a swing rod seat, one end of a lifting arm is adjustably and slidably connected with one side of the column, the other end of the lifting arm is hinged to one end of a connecting rod, one end of a swing rod upper sliding seat is adjustably connected with one side of the swing rod in a sliding manner, the other end of the swing rod upper sliding seat is hinged to the other end of the connecting rod, one end of a swing rod lower sliding seat is adjustably and slidably connected with the other side of the swing rod, and the other end of the swing rod lower sliding seat is hinged to an output end of a swing power mechanism. According to the mechanism, the reciprocating linear motion of a power unit can be converted into periodic rotation motion and then transmitted to the column so that the column swings left and right around a fixed hinge point in a reciprocating mode, the regular change of the motion track of the column is achieved through local adjustment of the relative position between adjustable components in the column, and the process requirement of synchronous linear adjustment of the inclination angle of the column is met.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a variable four-link swing mechanism. Background technique [0002] In the process of industrial production and manufacturing, we often use four-bar linkages. At present, most of the existing four-bar linkages are fixed planar linkage structures. The length and distance between the components in the existing four-bar linkages The connection position of the machine is fixed, and the regularity of its own motion trajectory cannot be changed, which cannot meet the differentiated process requirements on site. Contents of the invention [0003] The object of the present invention is to provide a variable four-link swing mechanism, which can convert the reciprocating linear motion of the power unit into periodic rotary motion and then transmit it to the variable four-link swing mechanism. Upright column, make upright column reciprocate swing left and right around fixed hinge p...
