A cam is the typical mechanical component used in the rotary-linear motion conversion mechanism. In this volume, we will look into application examples of the cam.

Cams are the excellent choice because of the following characteristics:

Based on these characteristics, cams are adopted in various applications including the terminal press fitting mechanism of a high-speed terminal press fitting machine, as well as the high-speed and complex timing control of an air release valve for an automobile engine. (See [Photo 1].) In the photo below, displacement of the plate cam is enlarged by the link mechanism. In order to ensure the high-speed responses, springs to prevent jumping have been installed.

A cam introduced here as the basics of automation clever mechanisms works as a supportive element that allows for quick attachment/detachment of fixtures by transforming the linear motion displacement into forces, rather than converting rotary motion into linear motion, which was explained earlier as a superior characteristic of cams used in motion control.
In [Fig.1], the rotary-linear motion conversion mechanism using a typical plate cam and a reciprocating follower is shown left and the one-touch clamp mechanism next to it.
