Embodiment Construction

[0032] The dynamic correction method of the three-coordinate measuring machine can be used to eliminate the Abbe error of various existing three-coordinate measuring machines, such as three-coordinate measuring machines that require double Y-axis guide rails, such as mobile bridge type, single-side elevated type, and gantry beam type three-coordinate measuring machines. measuring machine.

[0033] First, a corresponding displacement measuring device needs to be installed on the three-coordinate measuring machine, and the displacement measuring device can adopt a grating measuring device including a grating ruler and a scanning head. The two parallel Y-axis guide rail sides and the X-axis moving beam are respectively provided with displacement measuring devices.

[0034] When performing three-coordinate measurement on a measuring point, in addition to using the measuring probe to obtain the displacement data in the Z-axis of the measuring point, the displacement measuring devic...

Abstract

The invention relates to a dynamic revising method of a three-coordinate measuring machine, and the method comprises: displacement measuring devices are respectively arranged at the side of the two parallel Y-axial guide rails of the three-coordinate measuring machine; when the measurement is carried out by the three-coordinate measuring machine, the displacement measuring devices respectively obtain the data of the two displacements of an X-axial movement beam on the Y-axial guide rails and the displacement measuring device on the X-axial movement beam also synchronously obtains the data of the displacement of a measuring probe on the X-axial movement beam; and the calculation is carried out through the three-coordinate measuring machine according to the data of the three displacements to obtain the real-time displacement data of the measuring probe on a Y-axial guide plane. The dynamic revising method of the three-coordinate measuring machine provided by the invention has the advantages of reasonable design and low application cost, can be suitable for the improvement of the existing three-coordinate measuring machine and the manufacture of a new three-coordinate measuring machine, and can be used for effectively eliminating the influence of Abbe errors on the measuring result and also effectively improving the speed and efficiency of the measurement.

Description

technical field [0001] The invention belongs to the error correction technology of a three-coordinate measuring machine, in particular to a dynamic correction method for effectively eliminating the Abbe error of a three-coordinate measuring machine. Background technique [0002] The three-coordinate measuring machine is a high-precision measuring instrument. The coordinate measuring machine in the prior art can not only complete various complex measurements under the control of the computer, but also realize the control of processing by exchanging information with the CNC machine tool, and can also According to the measurement data, reverse engineering is realized. The coordinate measuring machine in the prior art is mainly composed of a host mechanical system (X-axis, Y-axis, Z-axis mechanism), a probe system, an electrical control hardware system and a computer data processing software system. Existing three-coordinate measuring machines mostly use two parallel horizontal...
