Embodiment Construction

[0031] The technical idea of ​​the present invention is based on the laser cladding technology. The powder feeding device is used to clad the powder on the worn surface of the inner hole of the waste spindle, and at the same time, it is melted by laser to combine with the thin layer metallurgical combination of the surface to be repaired in the inner hole of the main shaft, and solidifies rapidly. Finally, a surface coating with extremely low dilution and metallurgical combination with the inner hole thin layer material is formed, so as to repair the inner hole of the machine tool spindle and achieve the original performance of the matrix.

[0032] Below in conjunction with the attached in the embodiment of the present invention figure 1 , figure 2 and image 3 , to describe the technical solutions in the embodiments of the present invention;

[0033] The invention proposes a repair device based on the method of repairing the inner hole of the main shaft of a machine tool, ...

Abstract

The invention discloses a repair device and a repair method for a main shaft inner hole of a machine tool, and the repair device and the repair method are based on a laser cladding technology. Powdercovers a worn surface of a waste main shaft inner hole through a powder feeding device, the worn surface of the waste main shaft inner hole is in metallurgical bonding with a thin layer of a to-be-repaired surface of the main shaft inner hole through laser cladding, and a surface coating which is extremely low in dilution and is in metallurgical bonding with a thin-layer material of the inner holeis formed after rapid solidification, so that the main shaft inner hole of the machine tool can be repaired to achieve the original performances of a base body. The device consists of parts such as alaser unit, a laser cladding head, a powder feeding system, a cooling system and the like.

Description

technical field [0001] The invention relates to the technical field of devices matched with laser cladding and remanufacturing equipment, in particular to a method for repairing the inner hole of a machine tool spindle and a repair device for its application. Background technique [0002] At present, my country has more than 2 million traditional old machine tools, and most of the machine tools are in overdue service. The spindle is a typical machine tool component with high potential for recycling and remanufacturing value. The main shaft of the machine tool is responsible for transmitting torque and motion to the cutting tool. Once the inner hole on the main shaft is damaged, worn, or corroded by iron cutting, its geometric accuracy (such as end runout and radial runout) will be seriously affected, thus affecting Precision. Therefore, how to repair the inner hole of the main shaft has become the key to repairing the main shaft. [0003] At present, the processes for rep...
