Technical Field

The utility model relates to the technical field of laser cladding, in particular to a dustproof tailstock of a laser cladding machine tool.

Background

In recent years, the laser cladding technology is rapidly developed, and the technology becomes one of hot spots for research on laser processing technology at home and abroad. The laser cladding technology takes a high-energy laser beam as a heat source, and the powder material is clad on the surface of the part in a pneumatic or gravity powder feeding mode to prepare the high-performance protective coating, so that the performances of the surface hardness, abrasion resistance, corrosion resistance, oxidation resistance, high temperature resistance and the like of the material are improved, and the service life, the production efficiency and the product quality of the part are improved.

At present, a machine tool for cladding processing of shaft parts, such as a follow-up powder receiving device for a laser cladding machine tool, disclosed by publication No. CN214004787U and publication No. 2021, month 08 and day 20, is provided with a tailstock on a machine tool body for tightly propping up a workpiece, and meanwhile, the rotation center of the workpiece and the rotation center of a main shaft can be ensured to be concentric. Because the utilization rate of the powder of the laser cladding machine tool in the current market can not reach 100%, redundant metal powder can fall off and splash in the laser cladding processing process. The tail seat of the existing laser cladding machine tool often has non-cladding metal powder entering the tail seat of the machine tool in the use process, and particularly the metal powder is easier to attach to the center sleeve close to a workpiece, friction is generated between the center sleeve and the tail seat in the moving process of the center sleeve, so that the center sleeve is worn, and the tail seat cannot be normally used.

Therefore, the development of a dustproof tailstock of a laser cladding machine tool is an urgent problem to be solved aiming at the current situation that metal powder splashes and adheres to a top sleeve to cause abrasion in the cladding process of the tailstock used on the existing laser cladding machine tool.
