Example introduction: straight rod cone head locating pin and shouldered bushing in pick and place mechanism
Design summary:
①An example of using a swing cylinder to achieve linear and rotary motion through pneumatic drive, and moving a small substrate through a suction cup.
②In the case of a long pin, if the air vent is not provided, the pin and bushing are not easy to pull out. It is necessary to provide an air vent on the bushing side or the locating pin side.
Intended use of fixture bushing:
The axial structure of the swing cylinder can ensure positioning accuracy while saving space through the coordination of locating pins/shouldered bushings.
