How to Use a Locating Pin and a Locating Bushing in a Pair

Locating pins and locating bushings are used in pairs for the following purposes:

	1.	Locating pin and a Locating bushing in a pair
	2.	This lecture introduces examples of locating pins and locating bushings used in pairs.

Explanation 1

Free flow type automatic machines use many carriers. To reduce their weight and maintain their precision for over long periods of time, insert locating bushings into aluminum substrates.

Explanation 2

[Fig. 1] shows an example of item <3>. With a twist cylinder, linear and rotary motion can be obtained using an air drive. In this example, a small-size substrate is transferred using a vacuum pad. The locating pin and the locating bushing reduce the backlash (play) of the shaft structure of the twist cylinder. When a long pin is inserted, the pin and the bushing will become difficult to separate if there is no air release groove present. Make a relief hole in the bushing or a groove in the pin.

Explanation 3

[Photo. 1] shows a game machine comprised of a transfer robot employing an X-Y axis direct-acting unit and a rotary mechanism. These two units are mounted on independent base plates so that unit modification following a design change can be completed in a short period of time. Each unit is fastened to the frame of the machine body with a locating pin and a locating bushing.1. In order to reduce deterioration in positioning precision attributed to wear, and maintain stable precision over long periods of time by making locating bushings (or locating pins) replaceable. 2. In order to increase positioning precision of actuators (e.g. twist cylinders for pick and place), and reducing the sizes of pin and bushing pairs.
