Abstract

This utility model relates to the field of machining, specifically to an automatic mechanical clamp with adaptive function. It includes a base, a first clamping block structure on one upper side of the base, and a second clamping block structure on the other upper side of the base. Two positioning plates are fixedly connected to the base, and a hydraulic cylinder is mounted on the base. The hydraulic cylinder is fixedly connected to the base via a base plate, and its output shaft is fixedly connected to the first clamping block structure. The first clamping block structure includes a movable block, with both sides slidably connected to the positioning plates. A first groove is formed inside the movable block, and an adaptive component is disposed within the first groove. In this utility model, the holding process does not require frequent manual intervention or chuck changes. The adaptive component automatically adjusts to adapt to various workpieces, improving efficiency and safety. Flexible clamping avoids damage to the workpiece, making it suitable for precision or fragile parts. After machining, the workpiece can be released and removed by reversing the hydraulic cylinder operation, simplifying the process and increasing efficiency.
