[0002] As a key component of numerous industrial equipment and mechanical systems, the guide frame plays an indispensable role in automatic production lines, numerical control machine tools, logistics conveying equipment and various precision instruments and meters. It is like a "track guide", providing precise guidance and support for moving parts to ensure their stable and smooth operation on the preset path. The traditional positioning process relies more on manual experience and manual operation. Workers need to observe with their eyes, manually adjust the position and clamping degree of the clamp, which is greatly affected by subjective factors such as visual error, operation proficiency and fatigue. Different workers have different operation methods and judgment standards, resulting in poor consistency of positioning results. Long-term high-intensity manual operation is prone to fatigue and negligence, such as insufficient clamping force and positioning deviation, which has certain limitations in use.
