15 Factors while selecting a Gripper

The most common purpose of a gripper (often called the final effector) is to identify or surround parts for transport, insertion or assembly in automated manufacturing and processing systems. Gripper are also used in environments that are dangerous to a person's presence. To ensure adequate grip, several factors are required for selection and design. The following considerations will help you choose and change the size of the suitable clamp for your application.<br>

  1. Title:- 15 Factors while selecting a Gripper The most common purpose of a gripper (often called the final effector) is to identify or surround parts for transport, insertion or assembly in automated manufacturing and processing systems. Gripper are also used in environments that are dangerous to a person's presence. To ensure adequate grip, several factors are required for selection and design. The following considerations will help you choose and change the size of the suitable clamp for your application. 1. Part shape:- Two jaw clamps are generally used when a product or part has two opposite planes. If the piece is cylindrical, you can use three gripper jaws. The tools can be designed to accommodate cylindrical parts with two clamp jaws. 2. Accessibility and consistency of the piece:- The angular gripper are generally less expensive, but the arc movement of the jaw may require additional space of the tool and is held at various points as the width of the piece changes. It is easier to use parallel pliers to compensate for the size of the piece. 3.Weight of the piece:- The grip must be sufficient to transport the piece safely. 4.Orientation and dimensions: The orientation of the piece and the distance from the face of the gripper influence the selection of the clamp. 5.Size:- Nominal grip dimensions represent the approximate size of the gripper. 6.Deformation:- The minimum jaw movement of the gripper is determined by changes in the grip location or encapsulation. 7.Air pressure:- The air pressure of the gripper affects the size of the gripper, so it must be taken into account. 8.Open or closed grip:- The grip strength varies in each direction due to the effective area of the rod in some types of gripper. When changing the size, the grip direction must be taken into account. 9. Velocity:- Speed and acceleration / deceleration influence caliper selection. 10.Tool Length:- Long tool lengths make bending moments grip to affect size.

  2. 11.Tool configuration:- If the part is encapsulated, the required grip may be less than holding only flat parts. 12.Product maintenance:- if it is necessary to retain parts in case of loss of air, a spring or a locking cam can be assigned to the clamp. 13.Environment:- In hostile environments, special coatings or materials must be specified. 14.Synchronous operation:- Most gripper provide synchronized jaw movement. In special circumstances, an independent jaw travel is required and can be supplied upon request. 15.Exchange options:- Most gripper offer several exchange options.
