Gripper Actuation Types

The manufacturing industry has changed quickly during the past few years. Even though the industry used to be focused on a single robot producing one type of product at very high speeds, demands have changed. Therefore, many factories are turning to custom grippers that provide access to gripping automation features that can reduce manufacturing costs and meet customer demands. With numerous gripper actuation types, how can companies choose the best one to meet their needs?

Gripper Actuation

The first thing people need to consider is the gripper actuation. There are several types of gripper actuation, with common examples including manual actuation, pneumatic actuation, electric actuation, and hydraulic actuation. A few key points to keep in mind include:

  • Manual: If a gripper is being actuated manually, this means there is a real, hand crank, or lover involved.
  • Electric: There are also electric grippers that are actuated using a solenoid, electric motor, or another electrical source, controlling the jaws and fingers of the machine.
  • Hydraulic: A hydraulic gripper is actuated using hydraulic fluid that controls the vanes or cylinder of the device.
  • Pneumatic: A gripper that is actuated pneumatically is controlled using compressed air that acts on the vanes or cylinder of the machine.

There are numerous configuration options available. Usually, the number of grips on these machines falls between one and six, but the number can be customized to meet the needs of the user.

A Parallel Gripper

A parallel gripper is one of the most common gripper types available. Parallel grippers usually have a specific set of features that can be customized to meet the needs of the project. A few of the customizable options include the stroke, the gripping force, and the size of the grip itself. A few key points to keep in mind include:

  • The stroke refers to the available motion of each jaw or finger.
  • The gripping force refers to the force of the grip at a specific power. It is usually measured in pounds.
  • The gripping size is the size of the actual gripper attached to the machine. The size can also be specified to meet the needs of the user.

A parallel gripper is one of the most versatile options available, making it very popular.

Angular Grippers

Angular grippers are a bit different. They have a unique set of specifications that make them useful in a variety of settings. A few examples include:

  • The gripping torque refers to the power of the angular gripper and is usually measured in pounds.
  • The angular stroke is measured in degrees and refers to the operational angle of the finger.
  • The gripping size refers to the size of the gripper.

This is another popular option for those looking for a robot gripper.

A 3 Finger Robot Gripper

Another unique option is a 3 finger robot gripper. This is used to center a specific workpiece between the fingers. The fingers are usually 120 degrees apart. Then, the fingers come down, holding the object in place snugly. These robots come in a wide variety of sizes with numerous degrees of gripping force. The fingers can also be customized to close at a specific speed that makes the project faster without damaging the workpiece.

A Linear Gripper

Finally, a linear gripper is a basic option that can be useful in numerous situations. Usually, there is a mounting platform and a slider. The slider can be used to adjust the diameter between the two fingers. Then, there are two fingers that come together to grip the object. The fingers can be customized in terms of their size, strength, and closing speed.
