Cam shaft machining device

The utility model discloses a camshaft processing device, which relates to the technical field of camshaft processing, and comprises a processing table and a cam main shaft, the end part of the cam main shaft is connected with a crank, and a lower telescopic polishing mechanism and an upper telescopic polishing mechanism which are used for polishing burrs on the surface of the crank are sequentially arranged above the processing table. A fixed vertical plate is installed on the side face of the end of the machining table. The end portion of a cam main shaft on a crankshaft is arranged between the two opened clamping blocks, then the two clamping blocks are close to each other through the clamping air cylinder, the outer surface of the cam main shaft is rapidly clamped and fixed through the two clamping blocks, clamping efficiency is improved, the driving shaft rotates at a constant speed, and the clamping efficiency is improved. A cam spindle clamped by a clamping air cylinder is driven to rotate, the surface
