After the machining is finished, the motor 3 is controlled to rotate reversely, the top plate 9 is driven to loosen through the transmission mechanism, and the workpiece is taken out.
And a second working mode: in the clamping process, the real-time pressure detection is performed through the pressure sensor 8 to serve as closed-loop feedback, the clamping force is limited, and the clamp is applied to a combined clamp only playing a clamping role. Firstly, after the combined clamp is installed and fixed, a limit switch 7 is set to be larger or not set, after a workpiece is placed, a power supply is switched on, a motor 3 is started, a power assembly II drives an inner wedge block 5 to move downwards along a vertical chute 11 on a base 2, an outer wedge block 6 is extruded to be outwards pushed out along a horizontal chute 10 on the base 1, and a top plate 9 subjected to structural stress clamps the workpiece; when the pressure sensor 8 detects that the clamping force reaches a set value, the clamping of the workpiece is finished by the top plate 9 at the moment, the motor 3 stops, the clamping state is kept by the self-locking characteristic of the integral structure, and the workpiece machining is started. After the machining is finished, the motor 3 is controlled to rotate reversely, the top plate 9 is driven to loosen through the transmission mechanism, and the workpiece is taken out.
