Laser coaxial powder feeding composite manufacturing machine tool and workpiece composite manufacturing method

Abstract

The invention discloses a laser coaxial powder feeding composite manufacturing machine tool which comprises a cradle type workbench, a spindle, a material additive manufacturing mechanism, a material reducing machining mechanism and an online defect detection mechanism. The material additive manufacturing mechanism comprises a nozzle and a powder feeding device connected with the nozzle. A laser head is arranged at the position of the nozzle and connected with a laser generator. The material additive manufacturing mechanism is clamped by a nozzle bracket. The material reducing machining mechanism comprises a tool, a tool magazine and a tool changing bracket. The online defect detection mechanism comprises a defect detection head and a detection signal collection and analysis system. The invention further discloses a workpiece composite manufacturing method. The process of the workpiece composite manufacturing method mainly comprises the steps that material additive manufacturing, online defect detection and material reducing machining are carried out cyclically, and finally composite manufacturing is completed. By means of compounding of material additive manufacturing, material reducing machining and online defect detection, one-time forming of workpieces high in size precision and surface quality and low in internal defect is guaranteed, the production period is effectively shortened, and the part manufacturing quality and precision are guaranteed.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a laser coaxial powder feeding compound manufacturing machine tool and a workpiece compound manufacturing method. Background technique [0002] With the increasing demand for precision and complex parts in the aerospace, nuclear energy, and ocean engineering manufacturing industries, the emerging additive manufacturing technology has developed rapidly in the manufacture of complex parts due to its flexibility and high efficiency. However, the dimensional accuracy and surface quality of complex parts manufactured by additive manufacturing are often lower than the actual requirements. After additive molding, secondary material reduction (such as cutting, etc.) processing is required on traditional machine tools. Due to the need for secondary clamping and datum repositioning, the dimensional accuracy and shape accuracy of the workpiece are not high, the production efficiency i...
