The invention relates to a preparation method of a spliced anti-deformation lightweight carbon fiber composite material frame, belongs to the technical field of manufacturing of composite material frames, and aims to solve the technical problems that an existing connection mode is easy to loosen, and the rigidity and strength of joints are relatively weak. The preparation method comprises the following steps: step 1, preparing cylindrical carbon fiber composite material pipes by using a hollow rigid core mold, a sheet-shaped expansion glue film and fiber prepreg; step 2, arranging hole groove connecting structures on the cylindrical bodies; and step 3, building a single-layer frame with a grid structure by using the cylindrical bodies, wherein the cylindrical bodies are in cross connection through the hole groove connection structures to obtain intersection points of the grid structure. According to the technical scheme, the connecting rigidity and strength of the connecting part of the carbon fiber composite
