Abstract

The invention discloses a high-speed dividing mechanism of a back connection type cam connecting rod, which comprises a box body, an input shaft and an output shaft, wherein a conjugate cam is fixedly connected to the box body, axial lines of the input shaft and the output shaft are in one straight line, the transmission between the input shaft and the output shaft is realized by a parallel connection combined cam connecting rod mechanism which comprises the conjugate cam and one or two sets of connecting rod mechanisms, each set of connecting rod mechanism comprises an input rod fixedly connected to the input shaft and an output rod fixedly connected to the output shaft, a first connecting rod and a second connecting rod are sequentially hinged between the input rod and the output rod, the hinge point between the output rod and the second connecting rod is positioned in the middle region of the second connecting rod, and two ends of the second connecting rod are respectively in contact with inner outlines of two cams in the conjugate cam. Two end parts of the second connecting rod in contact with the inner outlines of the conjugate cam are provided with rollers. The two sets of connecting rod mechanisms are symmetrically arranged. The invention can meet the working condition requirement for higher dividing times of a high-speed automatic machine.

Description

technical field [0001] The invention relates to an indexing mechanism, in particular to an indexing mechanism for realizing high-speed intermittent motion. Background technique [0002] At present, the commonly used intermittent mechanism types are: indexing cam mechanism, ratchet, groove wheel and incomplete gear mechanism, etc. As we all know, ratchet, sheave, and incomplete gear mechanisms can only be used in occasions that do not require high operating speed and indexing positioning accuracy due to their shortcomings such as low indexing accuracy and high impact noise. The indexing cam mechanism, due to its high speed and high positioning accuracy, has been widely used in various automatic machines such as printing, textiles, medicine and food packaging, and electronic component assembly. [0003] There are three types of commonly used indexing cam mechanisms, including arc surface indexing cam mechanisms, cylindrical indexing cam mechanisms and parallel indexing cam me...
