What is the function of an air gripper?

Air gripper, which can realize various grasping functions, is a key part of the modern pneumatic manipulator. All the structures of the air gripper are double-acting, which can realize two-way grasping, automatic cendering, and high repetition accuracy. The grasping moment of the air gripper is constant; Non-contact detection switches can be installed on both sides of the cylinder, and there is a variety of installation and connections.

What is the function of the parallel air gripper?

When air is supplied, the parallel air grippers will approach the object and hold the object firmly for other operations, and when the air direction changes, the parallel air grippers will release the object. Typical applications are to change the direction of the object or to move the object during the selection and placement operation. Mainly used for handling, palletizing robot system. This kind of air pin is operated by a crankshaft gone-rod, which has small volume and large grip strength. The air gripper has a unique structure, which can be self-aligned and realize bidirectional grasping. It is an indispensable part of an industrial robot in the process of industrial production. That's what the parallel air grippers do.

How does a parallel air gripper work?

Parallel air grippers work with two pistons. Each piston consists of a roller and a double crank connected to a pneumatic finger to form a special drive unit. In this way, the pneumatic finger always moves axially to the center, and each finger cannot move independently. If the finger moves in the opposite direction, the previously pressurized piston is in the venting state and the other piston is in the pressurized state. Therefore, the parallel air gripper is driven by a single piston, the shaft drives the crank, the two gripper pieces each have a corresponding crank groove. In order to reduce the friction resistance, the gripper and the body are connected with a steel ball slide rail structure.

What is the purpose of the parallel air gripper schematic?

Through the parallel air gripper schematic diagram, we can know that the air gripper is driven by the cylinder driver; Two independent pistons, left and right, are installed in the cylinder block. Each piston is connected to an external air gripper, so that the movement of each piston indicates the movement of a single air gripper. In the application, three groups of piezoelectric valves control the high sensitivity proportional gas grippers. The piezoelectric valve is a servo proportional valve with no leakage and better dynamic performance in essence. One group is connected to the left end of the cylinder chamber, another to the right end of the cylinder chamber, and the third group is connected to the cylinder between the left and right pistons.
