Understanding the Anatomy and Function of Different Types of Pneumatic Grippers

Pneumatic grippers offer a powerful and precise way to automate industrial processes. They are cost-effective and can be used in a variety of applications such as manufacturing, assembly, and packaging. As technology continues to evolve, pneumatic grippers have become an integral part of most industrial robots and manipulators.

In this article, we will explore the anatomy and function of different types of pneumatic grippers. By understanding their anatomy and function, you will be able to make an informed decision when selecting the right pneumatic gripper for your application. 

Pneumatic gripper anatomy 

Pneumatic grippers come in a variety of shapes and sizes. Depending on the application, some grippers may have extra components such as a reach extension or an actuator. The most basic components include a gripper body, gripper fingers, and an actuator or control system. 

The gripper body houses the fingers, which are what actually grip the object being gripped. The fingers are made of hardened steel and come in various shapes and sizes to suit a wide range of applications. There is usually a safety catch to prevent unintended operation and prevent fingers from getting caught. 

The actuator is the part of the gripper that controls the movement of the fingers. Depending on the type of gripper, the actuator can be a motor, or pneumatically powered. 

Types of pneumatic grippers 

Pneumatic grippers are available in a variety of configurations to suit a variety of applications. The three most common types of pneumatic grippers are two-finger parallel grippers, three-finger angular grippers, and four-finger angular grippers. 

Two-finger parallel grippers 

Two-Finger Parallel Grippers are the most basic type of pneumatic grippers. They have two fingers that move in parallel and usually employ a rack and pinion system for operation. These grippers have a simple configuration, making them ideal for applications that require basic gripping and holding. They are not suitable for applications that require a greater grip force or a larger gripping range.

Three-finger angular grippers

Three-Finger Angular Grippers have three fingers that open and close collectively in an arc. This type of pneumatic gripper is well-suited for objects that require grasping from different angles. Thanks to the increased force generated by the three-finger configuration, three-finger angular grippers can generate a larger gripping force compared to two-finger grippers. 

Four-finger angular grippers 

Four-Finger Angular Grippers are the most powerful type of pneumatic gripper. The four-finger configuration allows the gripper to exhibit greater gripping force and a larger gripping range compared to the two- and three-finger grippers. 

Pneumatic grippers offer a cost-effective and powerful way to automate industrial processes. By understanding the anatomy and function of different types of pneumatic grippers, you will be able to make an informed decision when selecting the right gripper for your application. Whether you need a two-finger parallel gripper, a three-finger angular gripper, or a four-finger angular gripper, there is sure to be a pneumatic gripper that is suited to your specific needs.
