The invention relates to the technical field of rectifier cooling shell processing, in particular to a rectifier cooling shell manufacturing and processing equipment, including a processing table and a positioning device, the upper end of the processing table is fixedly installed with a positioning device, and the positioning device includes an inverted U-shaped plate, positioning cylinder, extruding plate, electric telescopic rod, moving frame, grinding frame and cleaning frame, the grinding frame includes moving plate, L-shaped frame, motor one, sprocket one, bracket, sprocket two, toothed chain belt , the grinding belt and the grinding plate, the present invention coordinates the processing table with the positioning device to position the heat dissipation shell, grinds the heat dissipation shell through the positioning device, and can clean the debris on the surface of the parts in time during the grinding process. During the process, workers are not required to perform processing operations, which improves the processing efficiency of the equipment for processing the heat dissipation shell, and at the same time ensures that the surface quality of the heat dissipation shell is uniform.
