Design and Analysis of Pneumatic Gripper with Two Jaw Actuavation
Authors:GUJJARLAPUDI KRISHNAVAMSI, G.ADI NARAYANA

Abstract: The designed robotic gripper in this paper is a two jaw actuated gripper which is different from the conventional cam and follower gripper in the way that controlled movement of the jaws is done with the help of pneumatic cylinders using air pressure. The force developed in the cylinder is very gentle and is directly delivered to the jaws in a compact way. The design and analysis of the gripper model are explained in details along with the detailed list of all existing pneumatic grippers in market. The force and torque for the gripper have been calculated for different set of conditions. The working of the model is checked for and observation for pay load is recorded at various pressures. The highly dynamic and highly accelerated gripper model can be easily set at intermediate positions by regulating the pressure. Pneumatic grippers are very easy to handle and are generally cost effective because air hoses, valves and other pneumatic devices are easy to maintain.

 INTRODUCTION 

          A pneumatic gripper is a specific type of pneumatic actuator that typically involves either parallel or angular motion of surfaces, A.K.A. “tooling jaws or fingers” that will grip an object. When combined with other pneumatic, electric, or hydraulic components, the gripper can be used as part of a "pick and place" system that will allow a component to be picked up and placed somewhere else as part of a manufacturing system. Some grippers act directly on the object they are gripping based on the force of the air pressure supplied to the gripper, while others will use a mechanism such as a gear or toggle to leverage the amount of force applied to the object being gripped. Grippers can also vary in terms of the opening size, the amount of force that can be applied, and the shape of the gripping surfaces— frequently called "tooling jaws or fingers". They can be used to pick up everything from very small items (a transistor or chip for a circuit board, for example) to very large items, such as an engine block for a car. Grippers are frequently added to industrial robots in order to allow the robot to interact with other objects. Some grippers in the market can move into intermediate positions with the help of a signal transmitter. Force- or position controlled grippers in closed.
