Lossless and rapid clamping machining clamp for automobile parts

The invention relates to the technical field of machining clamps, in particular to a lossless and rapid clamping machining clamp for automobile parts. The clamp comprises a machining table, a sliding rail, an extrusion mechanism and a clamping mechanism, wherein the clamping mechanism is composed of a fixed clamp, clamping grooves, a bottom plate, part grooves, a clamping block, a baffle, a transverse clamp, an extrusion block and a supporting rod. According to the lossless and rapid clamping machining clamp for the automobile parts, when the automobile parts are machined, the automobile parts are firstly placed on the bottom plate, one ends of the automobile parts are clamped into the part grooves, the bottom of baffle is clamped into the clamping block, one ends of the automobile parts enter the transverse clamp, the automobile parts extrude the extrusion block, under the action of a spring rod in the extrusion block, the automobile parts can be transversely limited, after machining is completed, the automo
