What are the differences between hydraulic grippers and mechanical grippers?

[DIG-DOG]

First of all, from the structural point of view, the hydraulic gripper is a grasping device that uses a hydraulic system to achieve opening and closing movements, usually composed of components such as a hydraulic cylinder, a hydraulic pump, and a control valve. The hydraulic gripper has a large grasping force and flexible operation, and is suitable for occasions with high grasping force requirements or harsh grasping environments. The mechanical gripper is a grasping tool that uses a mechanical structure to achieve opening and closing movements, usually composed of mechanical arms, connecting rods, gears and other components. The structure of the mechanical gripper is relatively simple and the cost is low, which is suitable for occasions where the grasping force requirements are not high.

Secondly, from the principle point of view, the action principle of the hydraulic gripper is to press the hydraulic oil into the hydraulic cylinder through the hydraulic pump, so that the piston of the hydraulic cylinder produces linear motion, thereby driving the grasping fixture to achieve opening and closing movements. The hydraulic gripper has simple operation and fast response speed, and can achieve high-precision grasping. The action principle of the mechanical gripper is to achieve opening and closing movements through the connecting rod transmission and gear transmission of the mechanical structure, which is suitable for occasions where the precision requirements are not high.

From the application point of view, the hydraulic gripper is suitable for occasions that require large grasping force and high precision, such as automobile manufacturing, ship assembly and other fields. Mechanical grippers are suitable for occasions where the gripping force is not high and the operation frequency is low, such as simple parts assembly, warehousing and logistics, etc.

In general, hydraulic grippers and mechanical grippers have their own advantages, and appropriate gripping tools should be selected according to specific gripping needs and working environments. Hydraulic grippers are suitable for occasions with large gripping force and high precision, while mechanical grippers are suitable for occasions where the gripping force is not high. In practical applications, the characteristics of both can be comprehensively considered and suitable gripping tools can be selected to improve production efficiency and product quality.
