Machining clamp for aviation complex molded surface workpiece

The invention relates to a machining clamp for an aviation complex molded surface workpiece, and relates to the field of aerospace machining. A machining clamp for aviation complex profile workpieces comprises a supporting transmission frame, two sets of oppositely-arranged flexible clamp modules and an auxiliary positioning device, the flexible clamp modules are installed on the supporting transmission frame, and the auxiliary positioning device is connected with a base of the supporting transmission frame through bolts. The flexible clamp module is mainly composed of an ejector pin body, a flexible clamp upper shell and a spring. The ejector pin body is partially exposed out of the flexible clamp upper shell; a spring is mounted at the lower end of the ejector pin body, the spring is fixed in a lower shell of the flexible clamp, and the ejector pin body can be locked through a self-locking bolt after sliding for a certain distance; and a space is reserved at the rail shell for supporting the transmission fr
