AI Technical Summary
In existing technologies, hinge positioning accuracy is low, especially when multiple hinges are positioned synchronously, it is difficult to guarantee relative position accuracy, resulting in long assembly cycles and poor consistency.
A tooling for hinge positioning is adopted, including a mounting bracket and a combination mechanism. Through the combination of a positioning device and a clamping device, the positioning cylinder and the clamping cylinder drive the pin and the Z-shaped pressure arm to achieve precise positioning and angle calibration of the hinge. Combined with the dual constraints of the groove and the calibration block, the accuracy of the hinge opening and closing angle is ensured.
Simultaneous positioning of multiple hinges was achieved, improving positioning accuracy and consistency, shortening the assembly cycle, and enhancing automation and positioning stability.
