Problems solved by technology

Moreover, when the mechanism needs to change the output swing angle of the driven rod, the length and position of the rod must be adjusted in the parking state, or the cam must be replaced, which is not only cumbersome to operate, but also labor-intensive and time-consuming, and the efficiency is very low; The adjusted mechanism can also only swing at another fixed swing angle

Abstract

The stepless rotation-oscillation converter as one mechanical driving assembly includes a coupling, a crank, a first stage of link rod, a second stage of link rod, a control unit, a lead screw, a shift nut, a parallel rocker, a third stage of link rod, an output rocker, a first stage of rocker, and a frame connected together. The stepless rotation-oscillation converter has the advantages of compact structure, broad swing angle range, on-line adjustability of the output swing angle amplitude and swing regulation, simple operation and high efficiency.

Description

technical field [0001] The invention relates to a rotation-oscillating stepless converter in mechanical transmission, in particular to a rotation-oscillating stepless converter which can convert input rotational motion into swing output, and whose output swing angle can be adjusted online. It can be used in textile, packaging, food and other light industrial machinery and equipment as a transmission component. Background technique [0002] At present, in textile, packaging, food and other light industrial machinery and equipment, the transmission parts that convert the input rotary motion into swing output adopt a four-bar linkage mechanism or a cam mechanism. The above-mentioned mechanisms are all one-stage transmission, and the driven rod ( Also known as the output rocker) the range of output swing angle is small. Moreover, when the mechanism needs to change the output swing angle of the driven rod, the length and position of the rod must be adjusted in the parking state,...
