Ultrasonic electric spark composite working platform

The invention discloses an ultrasonic electric spark composite working platform, and relates to the technical field of mechanical equipment. The number of the connecting frames is two, and each connecting frame is of an L-shaped structure. The two connecting frames are symmetrically fixed to the bottom of the right side of the workbench body front and back. The connecting block is arranged on the right side of the workbench body, and a lifting assembly is arranged between the connecting block and the connecting frame. A transverse air cylinder is arranged on the right side of the connecting block, and a limiting block is fixedly arranged after the pushing end of the transverse air cylinder penetrates through the connecting block; the two clamping plates are symmetrically arranged on the left side of the limiting block front and back, and clamping connecting assemblies are arranged between the clamping plates and the limiting block; according to the workpiece machining device, a workpiece can be clamped, and a
