Coaxial radial push rod high-speed dividing mechanism

Abstract

The invention discloses a coaxial radial push rod high-speed indexing mechanism, which includes a box body, an input shaft and an output shaft, the axes of the input shaft and the output shaft are on a straight line, and a driving ring is fixed at the end of the input shaft. At least one pair of symmetrical radial through holes are provided on the driving ring; at least one pair of symmetrical cranks are fixedly connected to the output shaft, and at least one first roller is respectively provided at the ends of the cranks; the inner profile is fixed on the box Line conjugate cam; each pair of symmetrical radial through holes on the driving ring is respectively provided with a push rod, and one end of the push rod is provided with a second roller, which is in contact with the inner profile conjugate cam; The other end of the rod is a flat-bottomed structure, and the flat-bottomed structure is in contact with the first roller at the end of the crank.

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...

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.
