Embodiment Construction

[0025] Such as Figure 1 to Figure 6 Shown, a kind of fast centering method of the present invention comprises the following steps:

[0026] (1) Transform the centering datum: use the XYZ three-way coordinate system to represent the centered product 10, and use the xyz three-way coordinate system to represent the target product 20, where the X and x directions represent the axial direction, and the Y and y directions Indicates the radial direction, Z direction and z direction represent the vertical direction, that is, the vertical direction. Select the YOZ plane on the centering product 10, select the yoz plane on the target product 20, and then make the first imaginary solid with the YOZ plane as one of the surfaces in the centering product 10, and make the yoz plane on the target product 20 It is the second imaginary three-dimensional of one of the surfaces, and the structure and size of the first imaginary three-dimensional and the second imaginary three-dimensional are ex...

Abstract

The invention provides a fast centering method. The method includes the following steps that (1) benchmark conversion is conducted on the centering benchmark, and a YOZ plane is selected for a centering product, a yoz plane is selected for a target product, and the YOZ plane and the yoz plane are the same in size; (2) parallel adjusting is conducted on the YOZ plane and the yoz plane till the YOZ plane is parallel to the yoz plane; (3) projection overlapping adjusting is conducted on the YOZ plane and the yoz plane till the YOZ plane is completely overlapped with the yoz plane in projection, and centering is finished. The fast centering method is high in measuring accuracy, good in centering effect and high in operation efficiency, accurate positioning of products super-long in length and low in rigidity is achieved, and fast centering is achieved through a closed-loop measuring feedback system, large-load supporting points and a drive device.

Description

technical field [0001] The present invention relates to a digitally controlled program control system characterized by a positioning control device, in particular to a fast centering method. Background technique [0002] A quick centering device is mainly used for the centering of two products. The product centering can generally be divided into two stages, that is, the centering positioning stage and the centering response stage. The rapid centering technology used in previous models first determines the positions of the two centered products through laser irradiation and reception. This is the centering positioning stage, and then the axis centering operation is realized through multi-step small displacement operations. This is the centering response stage . But this method has the following problems: [0003] The first problem is that this method of centering and positioning uses the centering of the axis, whether it directly uses the axis or the parallel line of the ax...
