Abstract

The invention discloses a single-drive intermittent pushing device based on a double-cam mechanism. The single-drive intermittent pushing device is composed of a double-cam movement component, two groups of pushing components and a mounting frame component. The outer contour of the cam is composed of arcs with large and small radiuses and non-arc curves connected to both sides. The two cams are fixedly connected to each other and perform circular motion with rotation driving. Each of the two groups of pushing components comprises a pulley, a spring, a guide shaft and the like. The pulley is inrolling contact with the cam. One cam drives the pushing components to perform the first-stage pushing motion, and then maintains intermittently stationary to achieve primary positioning. The other cam drives the pushing components to perform the second-stage pushing motion to achieve accurate pushing. Then the two groups of pushing components are simultaneously reset to complete a pushing motioncycle. One drive drives the two cams to rotate to realize two-stage intermittent pushing motion. The device is reliable in operation, easy to control, and can realize intermittent pushing of small equipment.

Description

technical field [0001] The invention relates to the field of automatic machinery, in particular to a single-drive intermittent pushing device based on a double-cam mechanism. Background technique [0002] In the general equipment manufacturing industry, electrical equipment manufacturing industry, machinery and electronics industry and national defense industry and other equipment manufacturing industries, automatic assembly of multiple electronic components is usually required, which requires a large number of two-stage or multi-stage intermittent push motion mechanisms, The primary positioning is completed by the first level of push, and then the second or more levels of push are used to achieve precise push. In the existing mechanism, multiple drives are required to realize the pushing action at each level, the reliability is low, the control is complicated, and due to the limitation of the structural size of the drive itself, it is difficult to realize the application in...
