Automatic centering method for end cover of centrifugal compressor

Abstract

The invention discloses an automatic centering method for an end cover of a centrifugal compressor, and belongs to the technical field of centrifugal compressors. The automatic centering method for the end cover of the centrifugal compressor comprises the following steps of placing the end cover on a working table; obtaining the initial position coordinates of the center of the end cover in a machine tool absolute coordinate system; obtaining the position coordinates of the center of the working table in the machine tool absolute coordinate system; determining the quadrant where the center ofthe end cover is located in a working table coordinate system according to the initial position coordinates of the center of the end cover and the position coordinates of the center of the working table; obtaining the distance R between the center of the working table and the initial position of the center of the end cover; obtaining the rotation initial phase angle of the end cover; and obtainingthe actual position coordinates of the center of the end cover in the machine tool absolute coordinate system at the rotation angle B of the working table. According to the automatic centering methodfor the end cover of the centrifugal compressor, the labor intensity of production personnel is reduced, and the alignment time is further shortened; and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of centrifugal compressors, in particular to an automatic centering method for an end cover of a centrifugal compressor. Background technique [0002] When processing the end cover of the centrifugal compressor, the end cover is usually processed in a boring machine processing system with a rotary table. Before processing the end cover, the center of the end cover needs to be adjusted to coincide with the center of the rotary table of the boring machine. [0003] However, to adjust the position of the end cover on the boring machine workbench, since the boring machine workbench does not have claws like the vertical lathe, it is very laborious to adjust the position of the end cover from front to back, left and right, especially for relatively heavy end covers, which is very difficult for the operator. No small burden. Contents of the invention [0004] The invention provides a method for automatic center...
