Abstract

The invention provides a parallel machine tool space dynamic accuracy detection method which aims at solving the problems that the partial space position cannot be detected and the difference of detection results is large when the detection is performed at different space positions by parallel machine tool dynamic accuracy detection methods in the prior art. The dynamic accuracy of the integral machining space of a parallel machine tool is monitored in a mode that detection point positions are arranged in the machining space of the parallel machine tool, the dynamic accuracy of every detection point position is detected through a five-coordinate dynamic accuracy detection tool, and the detection blind area is eliminated by a mapping method. According to the parallel machine tool space dynamic accuracy detection method, the dynamic accuracy detection can be completely performed on the machining space of the parallel machine tool and accordingly the machining quality and efficiency of parallel machine tool products is effectively improved, the operation is simple and convenient, and detection data are real and reliable.

Description

technical field [0001] The invention relates to a space dynamic precision detection technology of a parallel machine tool, in particular to a space dynamic precision detection method of a parallel machine tool. Background technique [0002] Due to its unique mechanical structure, parallel machine tools are different from ordinary five-coordinate machine tools in terms of dynamic accuracy inspection. Ordinary five-coordinate machine tools use the fourth and fifth coordinate axes to rotate independently, but parallel machine tools must be carried out under the condition of five-axis linkage, so when testing the dynamic accuracy, using the dynamic accuracy detection method of ordinary five-coordinate machine tools cannot reflect the complete dynamic accuracy . Due to the unique structure of the parallel machine tool, when the deflection angle of the A / B axis is different, the moving range of the parallel axis in the Z direction is also very different. For example, when the de...
