The invention has good structural strength stability and universality, high integration, modularization and intelligence, can effectively meet the requirements of different machining equipment and the machining matching operation of camshafts with different diameters in the aspect of , can realize the auxiliary supporting and positioning of the camshaft workpiece while performing cooling and lubricating operation on the camshaft workpiece, avoids the condition that the coaxiality of the workpiece is influenced due to the feeding action force of a cutter and the gravity factor of the camshaft workpiece in machining, and improves the machining operation precision, can accurately realize the high-efficiency cooling and lubricating operation on a machining operation surface, a workpiece surface and a machining cutter in the aspect of operation, greatly improves the machining operation quality and efficiency of the workpiece, effectively prevents the condition that the structural strength and the service life of the workpiece and the cutter are seriously influenced by the damage of the workpiece surface caused by high temperature in the machining operation, annealing of the workpiece and the cutter caused by high temperature, and the like, and further realizes the accurate control of the use amount of the cooling agent and the lubricant, greatly reduces the use amount of the cooling agent in the cooling and lubricating operation, thereby reducing the use cost of the coolant and the equipment, the environmental pollution caused by overlarge use amount of the coolant, and the machining efficiency of the camshaft in the .
