Problems solved by technology

[0016] In order to meet the requirements of the three commonly used indexing cam mechanisms in the prior art that are difficult to achieve greater indexing times and higher indexing speeds, the present invention provides a coaxial radial push rod high-speed indexing mechanism. The indexing mechanism organically combines the characteristics of the cam mechanism and the link mechanism to overcome the shortcomings of the three commonly used indexing cam mechanisms in the prior art, such as small selection range of indexing numbers, large relative volume, and low indexing times.

Abstract

The invention discloses a co-axial type radial thrust rod high speed indexing mechanism, comprising a box body, an input shaft and an output shaft. The axial lines of the input shaft and the output shaft are on a same line; the end part of the input shaft is fixed with a driving cirque which is provided with at least a pair of symmetrical radial through holes; the output shaft is fixedly connected with at least a pair of symmetrical cranks; the end part of the crank is respectively provided with at least one first roller; the box body is fixed with an internal profile conjugate cam; each pair of symmetrical through holes on the driving cirque are internally provided with a thrust rod respectively; one end of the thrust rod is provided with a second roller which is contacted with the internal profile conjugate cam; the other end of the thrust rod is in flat bottom structure which is contacted with the first roller at the end part of the crank. The indexing mechanism of the invention can be widely applied to automatic machines with large indexing number range, compact structure, large rigidity, high bearing force, coaxial input and output and high speed indexing intermittent motion, such as various machines of printing, packaging, foods, ceramics, pharmacy, military industries, etc.

Description

technical field [0001] The invention relates to an indexing mechanism, in particular to a coaxial high-speed indexing mechanism. Background technique [0002] Currently commonly used intermittent mechanism types are: cam indexing mechanism, ratchet, grooved 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 cam-type indexing mechanism has been widely used in various automatic machines such as printing, textiles, medicine and food packaging, electronic component assembly, and military machinery due to its high speed and high precision. [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 mechanisms, such as f...
