[0019] Working principle: The workpiece is rotated by driving the spindle box and the tailstock to clamp it. After the laser cladding head is adjusted to the specified height, it can be clad. During the cladding process, excess metal powder will fall off the workpiece. The L-shaped bellows can move with the support column and is located below the laser cladding position. It can catch the detached metal powder in time, and then suck the caught metal powder into the powder collecting box under the action of the vacuum pump. The metal powder floating around the processing position will be sucked into the powder collecting box through the exhaust holes set on the inner side of the L-shaped bellows under the action of the vacuum pump, so as to collect the metal powder that falls off the workpiece and prevent it from easily entering the machine tool transmission. The moving parts or floating in the surrounding environment ensure the accuracy of machine tool operation and environmental protection; when the laser cladding head performs cladding processing on both ends of the workpiece, the L-shaped bellows is provided with a sliding connection structure with the movable support plate, a fixed support plate, a limit plate and a spring matching structure. When the L-shaped bellows contacts the driving spindle box or the tailstock, the movable support plate can continue to move, which is convenient for the laser cladding head to perform cladding processing on both ends of the workpiece, and at the same time, it is convenient for the L-shaped bellows to have a certain width to increase the powder receiving area. In addition, when the cladding processing is performed on both ends of the workpiece, a hard collision occurs between the L-shaped bellows and the driving spindle box or the tailstock.
