Coaxiality alignment method

Abstract

The invention relates to a coaxiality alignment method which is characterized by comprising the following steps: manufacturing a tool which consists of a standard core bar, a dial gauge stand and a lever indicator which are connected together; feeding the standard core bar into a standard hole of a combined workpiece, adhering the support end of the dial gauge stand on the end surface of a bracket of the standard core bar; rotating the standard core bar, moving the dial gauge stand to an inner hole to be detected; aligning the center of the combined workpiece with a processing hole to be just aligned to the center of the standard core bar, namely, the center of the combined workpiece with the processing hole is concentric with the standard hole; and roughly boring the hole to be processed, and finely boring the hole to be processed till the design size. By adopting the coaxiality alignment method provided by the invention, the alignment tool is simple in structure, easy to manufacture and simple and convenient to use and operate; due to the dial gauge and a fine tuning coordinate system, high alignment accuracy and precision can be achieved, the assembling and disassembling times of the combined workpiece can be reduced, the assembling and disassembling working intensity can be alleviated, the processing efficiency and the processing quality of the combined workpiece can be improved, the reliability is good, the processing cost is lowered, the economical efficiency is high; influence of artificial factors is reduced, and the processed combined workpiece is good in quality stability consistency.

Description

technical field [0001] The invention relates to a process method, in particular to a coaxiality alignment method. Background technique [0002] The difficulty in the processing of large-scale transmission gearboxes is mainly due to the high requirements for shape and position tolerances in combined processing, especially the very high requirements for the coaxiality of the bearing holes at both ends. Due to the influence of equipment precision and human factors, it is difficult to ensure the same axis requirements. The existing alignment method is: the center of the mandrel is set as the coordinate system of the hole system at one end of the workpiece, and the rough boring is carried out, the table is rotated 180°, and the center of the mandrel is set as the hole at the other end of the workpiece Coordinate system, in this coordinate system rough boring, repeated many times to achieve the required coaxiality. The disadvantage of this alignment method is that it takes a lon...

Problems solved by technology

The disadvantage of this method of alignment is that it takes a long time to align, and the labor intensity is high. Secondly, there are many human factors, and the processing is performed while the watch is being played. The quality of the processed parts is unstable and the consistency is poor.
