Problems solved by technology

[0002] Traditional processing methods are relatively easy to automate and intelligently polish the plane of metal parts, but it is more difficult to polish metal parts with arbitrary three-dimensional curved surface features. Therefore, most of this type of polishing work still relies heavily on manual work. , poor polishing accuracy, low efficiency, lack of consistency an...

Embodiment 1

[0028] Example 1: See Figure 1-4 , a three-dimensional curved surface laser polishing equipment, including equipment bed 1, an inert gas cylinder 7, an oxygen concentration tester 14 and a built-in QBH collimator 11 with a beam expander, the inside of the equipment bed 1 is equipped with Built-in quasi-flat-top continuous laser 19, the built-in quasi-flat-top continuous laser 19 converts the quasi-flat-top beam into a flat-top beam through beam shaping technology, the diameter of the spot produced by the laser is 1-2mm, and the laser beam passes through the built-in QBH collimator and the beam expander 11, enter the three-dimensional galvanometer 12; the height of the three-dimensional galvanometer can be adjusted by moving the axis 10; the switch box 9 is provided with a laser and a close switch with the galvanometer; the laser output by the three-dimensional galvanometer penetrates through the scanning process. Quartz glass 5 acts on the three-dimensional curved surface of ...

Embodiment 2

[0040] Embodiment 2. On the basis of Embodiment 1, the built-in quasi-flat-hat continuous laser 19 of this design can also be replaced by a Gaussian beam continuous laser, and then the Gaussian beam is converted into a flat-hat beam by beam shaping technology for use in this design.

Abstract

The invention discloses a 3D surface laser polishing method and device. The device comprises a device lathe bed, an inert gas bottle, an oxygen concentration tester, a 3D galvanometer and an internalQBH collimator with a beam expander. An inner quasi flat top continuous laser device is arranged in the device lathe bed, an inert gas seal cabin is arranged above the device lathe bed, an electromagnetic chuck is arranged in the inert gas seal cabin, and the inert gas seal cabin is connected with an inert gas seal cabin air inlet pipe through an inert gas seal cabin air inlet valve. The device has the beneficial effects that firstly, 3D surfaces of a plastic injection molding mold cavity and a blowing plastic mold cavity are subjected to laser polishing; secondly, 3D surfaces of a general anddedicated structural part or metal parts of the device can be subjected to laser polishing; and thirdly, the metal 3D surface for decoration can be mechanically polished.

Description

technical field [0001] The invention relates to a polishing device, in particular to a three-dimensional curved surface laser polishing method and equipment. Background technique [0002] Traditional processing methods are relatively easy to automate and intelligently polish the plane of metal parts, but it is more difficult to polish metal parts with arbitrary three-dimensional curved surface features. Therefore, most of this type of polishing work still relies heavily on manual work. , Poor polishing accuracy, low efficiency, and lack of consistency and stability in polishing quality. What's more, manual polishing work is extremely monotonous and boring. With the development trend of higher and higher integration of manufacturing process automation, fewer and fewer workers are willing to engage in this manual work. Many manufacturing companies are facing the loss of polishing technicians. , followed by the plight of lack of people. This phenomenon occurs in the polishing...
