That is to say, if the working range of the mechanical platform changes, it is necessary to replace the calibration plate with a matching size, and it is necessary to remake the calibration plate. As the working range of the mechanical platform further increases, it will not be possible to make a calibration plate of the corresponding size or manufacture A calibration plate of the corresponding size requires a large price

The invention belongs to the technical field of machining and relates to an error correction method and device for a mechanical platform. The method comprises the following steps: 1, a calibration plate of a predetermined specification is used to calibrate the mechanical platform for multiple times, an area, covered by the calibration plate, on the mechanical platform is defined as a calibration area, wherein the calibration area comprises a first calibration area and a second calibration area; the angle deviation of a reference point in the second calibration area relative to a reference point in the first calibration area is calculated; and the coordinate position of the reference point in the second calibration area is adjusted according to the angle deviation; the translation deviationof the reference point in the second calibration area is calculated according to the angle deviation; and the coordinate position of the reference point in the second calibration area is adjusted according to the translation deviation. According to the error correction method and device for the mechanical platform of the invention, the whole mechanical platform is calibrated through one calibration plate; and errors existing in the calibration area are adjusted through the angle deviation and the translation deviation. Therefore, errors brought by the machining errors of the mechanical platform to products needing to be machined are corrected.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an error correction method and device for a mechanical platform. Background technique [0002] At present, all walks of life need to use mechanical platforms to process products. For example, the mechanical platforms can be, but are not limited to, CNC machine tools, 3D printers, laser cutting tools, etc. The current mechanical platforms are all processed according to the set ideal size to ensure the accuracy of the produced products. However, due to the processing technology of the mechanical platform, there is often an error between the size of the actually processed mechanical platform and the ideal state. For example, the ideal mechanical platform takes any corner as the origin, and the entire plane is in the state of a standard rectangular coordinate system. , but due to processing errors, the actual plane of the mechanical platform is in the state of a rectan...
