Air gripper is the use of cylinder drive to complete the task, you can work according to the size of the required force to determine the thrust and pull on the piston rod.
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.

l Common problems and solutions when using air grippers?
1. Three groups of piezoelectric valves are used to control the high sensitivity proportional gas grippers. In essence, the piezoelectric valve is a servo proportional valve with no leakage and better dynamic performance. 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.
2. The pressure in the three chambers is monitored and controlled by three pressure sensors. Three sets of piezoelectric valves control the pressure in each chamber. By adjusting the pressure in the cylinder chamber at both ends of the piston (air gripper), the clamping force of the air gripper can be adjusted. In addition, the position of the air gripper is controlled by installing a position sensor.
In the process of designing the air gripper, the design drawing of the air gripper should be reasonably planned according to the actual production situation. First of all, the size, shape and quality of the workpiece should be considered for the purpose of use, and the appropriate flat open and close type or branch grind and close type should be selected. According to the shape of the workpiece, external measurement, use environment and use purpose, set the type of air gripper. The size of the air gripper is selected according to the size of the holding force, the distance of the clamping point, the extension and the stroke. Therefore, a reasonable air gripper design has a very important impact on the product. High quality air gripper is easy to achieve high accuracy, can save the cost of workpiece processing, so that enterprises get more economic benefits.
1. Before using the air gripper, it is necessary to effectively check whether the installation connection points are loose or not, and a safety interlock should be considered in its operation. When sequential control is carried out, each working position of the air claw should be checked.
2. When the air gripper is used in a dusty environment, a dust cover should be arranged on the piston rod. A filter should be installed on the breather hole of a single working air gripper to prevent dust from being sucked from the breather hole. For the air gripper that needs oil mist to be lubricated, the lubricating oil selected should be used to avoid expansion and contraction of the sealing ring, and no emulsification with the moisture in the air.
3. Before the air gripper is connected to the pipeline, the dirt in the pipeline must be removed to prevent debris from entering the air gripper. The working temperature of the air gripper is usually 5 ~ 60℃. When the air gripper is used at the following 5℃, it sometimes has adverse effects on the action of the air gripper due to the condensation of moisture contained in the compressed air.
