Mechanical structure of micro-gripping system: the cornerstone of precise control

Material science of gripper: double guarantee of strength and durability
The gripper of micro-gripping system, as the part that directly contacts the operated object, the material selection is crucial. With the continuous progress of material science, grippers are usually made of high-strength and high-corrosion-resistant materials, such as stainless steel or special alloys. Stainless steel has become one of the preferred materials for gripper manufacturing due to its excellent mechanical properties and good processability. It can not only withstand a certain load without deformation or damage, but also maintain stable performance in a variety of harsh environments, such as humid, high temperature or corrosive environments.

For occasions that require higher strength, lighter weight or specific electromagnetic properties, special alloys become a better choice. These alloys often adjust the composition ratio to obtain better comprehensive properties than traditional stainless steel, such as higher yield strength, lower density or specific magnetic permeability, so as to meet the needs of specific application scenarios.

Precision mechanical design: the source of smooth and stable action
In addition to the selection of materials, precise mechanical design is also the key to ensure precise control of micro-gripping systems. The opening and closing action of the gripper needs to be designed to be fast and accurate, while ensuring smoothness and stability throughout the entire operation. This requires designers to not only consider the movement trajectory of the gripper when designing the mechanical structure, but also optimize the layout and parameters of key components such as the transmission mechanism, guide mechanism and locking mechanism.

Transmission mechanisms, such as gears, screws or connecting rods, are responsible for converting the driving force into the opening and closing movement of the gripper. By accurately calculating the transmission ratio and selecting transmission elements with low friction coefficients, energy loss and mechanical wear can be effectively reduced, and the transmission efficiency and accuracy of the system can be improved. Guide mechanisms, such as guide rails or guide shafts, ensure that the gripper moves smoothly along the predetermined path during the opening and closing process to avoid deflection or shaking. The locking mechanism is responsible for stably fixing the operated object in the clamping state to prevent it from falling off or loosening.

Reducing mechanical friction: the key to improving accuracy
Mechanical friction is one of the important factors affecting the accuracy of micro-gripping systems. In order to reduce the error caused by friction, designers need to take a series of measures. For example, choose materials with low friction coefficient as sliding surfaces, such as applying lubricating layers or using rolling friction instead of sliding friction; optimize the geometry of the clamp and transmission mechanism to reduce the contact area and friction resistance; and ensure close fit and stable movement between components by accurately adjusting the preload and clearance.

In addition, regular maintenance and care are also necessary to reduce mechanical friction and maintain system accuracy. This includes cleaning sliding surfaces, checking and replacing worn parts, adjusting lubrication systems, etc.
