Centering system and method for three-dimensional printing equipment jetting head and numerical control equipment tool

Abstract

The invention belongs to the fields of three-dimensional printing techniques and numerical control machining and discloses a centering system and method for a three-dimensional printing equipment jetting head and a numerical control equipment tool. A clamp support is mounted on an equipment Z shaft through mounting holes. The equipment Z shaft is provided with a laser device through a fastening bolt in a second containing hole. A two-dimensional high-precision position sensing device (PSD) is fixed to the center of an equipment C shaft working rotary table. A high-precision position sensing device (PSD) signal acquisition and processing plate is used for processing signals acquired by the position sensing device (PSD) and converting the signals into recognizable digital signals, arranged on an equipment plane and connected with the two-dimensional high-precision position sensing device (PSD) and an upper computer. By means of the centering system and method, the printing jetting head Z-direction centering problem existing in 3D ink-jet printing and the XOY plane center calibration problem in numerical control machining are effectively solved; the centering system is simple in design, ingenious in structure, good in application effect and long in serve life and serves as a PSD centering device for Z-direction centering of the 3D ink-jet printing jetting head and XOY plane tool setting in numerical control machining.

Description

technical field [0001] The invention belongs to the field of three-dimensional printing technology and numerical control processing, and in particular relates to a centering system and method for nozzles of three-dimensional printing equipment and tools of numerical control equipment. Background technique [0002] Three-dimensional printing technology is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. With the development of 3D printing technologies such as material science, laser technology, manufacturing science and information technology, 3D printing systems and equipment are becoming more and more perfect. In the 3D printing process, there are many factors that affect the accuracy of the product, such as the accuracy of the printer itself, the performance of the material, the process parameter settings during the printing...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: ①When the working platform of the equipment is movable or detachable, the origin or center of the working platform often needs to be calibrated multiple times; The method in the middle method is complicated to operate, not only takes a lot of time and energy, but also the accuracy is not very high; ③At the same time, because the print nozzle itself is fragile and cannot directly contact the workpiece and the turntable, the ordinary tool setting instrument cannot be used directly
