3D printer planar motion precision measuring device

Abstract

The invention discloses a 3D printer planar motion precision measuring device. The 3D printer planar motion precision measuring device comprises a base, an X-direction guide rail, a Y-direction guide rail, an X-direction sliding plate, a Y-direction sliding block, a Y-direction grating reading head, a Y-direction grating scale, an X-direction grating scale, a data processing system, and an X-direction grating reading head. The 3D printer planar motion precision measuring device is advantageous in that a structure is simple, use is convenient, and production costs are low; during use, requirements on testing environment are low, and the 3D printer planar motion precision measuring device can be used in a production scene for measurement; during actual measurement, the data processing system is used for real-time acquisition of position numbers from the X-direction grating reading head and the Y-direction grating reading head, and the CPU is used for the real-time processing of the acquired data, and is used to output actual motion coordinate data including X-direction positions and Y-direction positions to related data communication interfaces; during the phase, the CPU is used to form a dynamic motion curve chart by the fitting of the actual motion coordinate data, and is used to display the dynamic motion curve chart visually by a display screen, and then a user can be aware of an actual measurement result conveniently.

Description

technical field [0001] The present invention relates to a measuring device, in particular, the present invention relates to a motion accuracy measuring device, in particular to a 3D printer plane motion accuracy measuring device. Background technique [0002] Fused deposition 3D printer is a rapid prototyping device using additive technology. It moves the extrusion nozzle according to the motion trajectory in the XY plane and extrudes the molten molding material. When a layer is completed, the relative position of the extrusion nozzle in the Z direction is changed. , and then carry out another layer of molding operations, and finally form the required three-dimensional model or product through layer-by-layer molding. The above-mentioned XY motion trajectory accuracy determines the molding accuracy, so the measurement of the XY motion trajectory accuracy is conducive to improving the molding accuracy of the 3D printer. There are two states for measuring the accuracy of XY mo...
