Laser cladding self-adjusting device and method

Abstract

The invention provides a laser cladding self-adjusting device and method. The device comprises a spindle motor, a chuck, an upright column, a Z-axis module, a bracket, a laser cladding head, a first ranging sensor, a control system, a base, a spindle seat, an X-axis module, a second ranging sensor, a tailstock and a cladding material input mechanism, wherein the first ranging sensor is used for detecting a distance between the surface of a workpiece to be cladded and the laser cladding head in real time, and the second ranging sensor is used for detecting a distance between the cladded surfaceof the workpiece and the laser cladding head in real time. According to the device and the method, the automatic fixed height control and accurate time difference control are innovatively arranged, the distance between the cladding head and the workpiece is monitored in real time, the distance between the cladding head and the workpiece is automatically adjusted, and the constant distance betweenthe cladding head and the workpiece is guaranteed; and meanwhile, the height difference before and after cladding is monitored in real time, the execution time is accurately controlled, the process conditions are dynamically adjusted, the constant thickness of the cladding layer is guaranteed, and a problem of development bottleneck of an existing laser cladding technology is solved.

Description

technical field [0001] The invention relates to the technical field of laser cladding, in particular to a laser cladding self-regulating device and a self-regulating method. Background technique [0002] Parts corrosion is the main cause of damage to mechanical equipment. The quality of anti-corrosion ability of parts is directly related to the safe operation of mechanical equipment. Cladding alloy powder or alloy wire on the surface of workpieces by laser is a recently developed anti-corrosion technology. , called laser cladding technology, this technology requires the base material, cladding material, and laser focus to intersect to form a molten pool, changing the distance will change the quality of the laser, limited by the accuracy of the cladding equipment, the cladding process Problems such as thermal deformation in the center and surface defects of the remanufactured old parts may cause the distance between the cladding head and the workpiece to be in a dynamic chang...

AI Technical Summary

Problems solved by technology

Therefore, limited by different types of workpieces, different material utilization rates, or differences in each batch of materials, fluctuations in cladding thickness, etc., the laser cladding equipment in the prior art cannot guarantee the quality of the cladding head because it does not have a self-adjusting function. The constant distance from the workpiece and the constant thickness of the cladding layer hinder the development of laser cladding technology
