Manual vises are more common on machine tools. During operation, the workpiece is clamped mainly by manually turning the screw handle to push the clamping block to move linearly. The operator adjusts the clamping force of the workpiece by understanding the physical properties of different materials and observing and analyzing the shape of the workpiece. Pneumatic vises and hydraulic vises are convenient and quick to clamp, but there are problems such as the clamping force is not easy to adjust and needs to be equipped with related auxiliary equipment such as air source and hydraulic source.

In addition, it can be seen from the above technology that a servo motor direct drive is used, and its driving torque is also limited, which makes it difficult to adapt to occasions with higher demands on clamping force. Therefore, an electric drive torque converter is urgently needed to solve the above problems. Utility Model Content
