AI Technical Summary
In existing automobile production lines, the positioning devices of the grippers are difficult to meet the requirements of flexible assembly of multiple models, and the grippers are inconvenient to replace, which affects the accuracy and stability of welding.
A gripper positioning device including a vertical frame and a clamping mechanism is designed. The gripper is accurately positioned and securely connected by the cooperation of the first and second clamping mechanisms and the positioning pin and pin hole. A safety locking mechanism is provided to prevent shaking. The clamping block and cylinder ensure the stability of the gripper on the vertical frame.
It achieves accurate positioning and stable connection of the gripper on the vertical frame, facilitates gripper replacement, improves welding accuracy and stability, and meets the flexibility requirements of automobile production lines.
