The invention relates to the technical field of the wire harness stripping machine, and discloses a stripping machine for automobile wire harness processing. The stripping machine comprises a base, the stripping machine disclosed by the invention is characterized in that one side of an upper end of the base is fixedly connected with a support plate, the center of one side of the support plate is fixedly connected with an air cylinder, an output end of the air cylinder penetrates through the support plate and outward extends and is fixedly connected with a mobile plate; a fixed plate is fixedlyconnected to a location, corresponding to the mobile plate, of the upper end of the base; one side, far away from one end of the air cylinder, of the mobile plate is fixedly connected with a mobile cutter; a fixed cutter is fixedly connected to the location, corresponding to the mobile cutter, of the fixed plate, the other side, corresponding to the mobile cutter, of the mobile plate is connectedwith a mobile clamp splice through a buffer mechanism; and a fixed clamp splice is fixedly connected to the location, corresponding to the mobile clamp splice, of the fixed plate. The processing speed is obviously improved, the wire harness cannot be damaged due to the influence of the subjective factor in the stripping, the product quality is improved, and the product is stable and reliable.
