Problems solved by technology

However, the contact auxiliary support will cause the workpiece and the bracket to vibrate due to the contour shape and size error of the workpiece. Especially in the case of clamping a heavy workpiece by the spindle of the cladding machine tool, the vibration of the workpiece and the bracket is extremely significant, and it is more likely to cause resonance, which seriously affects Machining accuracy and threats to production safety

Abstract

The invention provides a dynamic adjusting method, device and system for the height of a laser head of a laser cladding machine tool. The current working area is dynamically interpreted through a displacement sensor which is installed to be parallel to the laser cladding head and has forward bias in the feeding direction in the machining process of the laser cladding machine tool, after the lasercladding head moves to the corresponding portion, parameters of a corresponding regional interpolation function are taken out, a deflection compensation error of a workpiece at the current position isgenerated, the height of the laser cladding head is dynamically adjusted, and then the deflection deformation error of the workpiece is eliminated. Therefore, deflection deformation of the workpieceis compensated in real time, the machining quality is improved, and the advantages of being high in precision, real-time property and dynamic property, simple in structure, convenient to maintain andthe like are achieved.

Description

technical field [0001] The disclosure belongs to the technical field of laser heads of laser cladding machine tools, and in particular relates to a method, device and system for dynamically adjusting the height of laser heads of laser cladding machine tools. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Laser cladding is a modification technology that uses a high-energy laser beam to rapidly melt the cladding material and the surface of the substrate, thereby producing a coating surface with completely different composition and properties. Since laser cladding can obtain high hardness, wear-resistant, corrosion-resistant, high-temperature resistant coatings and thermal barrier coatings, it is widely used in national defense, aerospace, mining machinery, petrochemical, automobile and shipbuilding, mold metallurgy and other industries.
