Quick replacement method and replacement error adjustment method for impeller part

Abstract

The invention discloses a quick replacement method and a replacement error adjustment method for an impeller part. In the quick replacement method, a universal sub-board structure is adopted and connected with different tools to form a combination for clamping different parts, the combination as a carrier is first subjected to part clamping and alignment outside a machine, and then all-process transfer of the parts from the outside of the machine to a machine tool is achieved through quick replacement of a sub-board and a mother board. The replacement error adjustment method compensates for aninfluence value of the end face runout on the circumferential runout by adjusting the circumferential runout of a single mother board. According to the quick replacement method and the replacement error adjustment method for the impeller part, high-precision, fast and automatic clamping positioning of the impeller part can be achieved, the replacement efficiency is improved, and the device utilization rate is improved.

Description

technical field [0001] The invention relates to a method for quick replacement of impeller parts, and also relates to a method for adjusting errors generated during quick replacement of impeller parts, which belongs to the technical field of tooling design. Background technique [0002] The impeller parts belong to the key products in aerospace engines, such as figure 1 As shown, it has the characteristics of complex structure, high design index requirements, high processing difficulty, and long processing cycle. Among them, the CNC blade milling process of the impeller is the key process of the part, and it is also the process with the longest working hours in the whole process, and the processing accuracy of this process is Key design indicators that directly affect the product. [0003] Due to the high profile requirements of the blades of impeller parts, in the CNC blade milling process, it is generally required that the runout of the end face of the part is not greater...

AI Technical Summary

Problems solved by technology

[0005] (1) In order to ensure the high clamping accuracy of the impeller parts, the time for clamping and alignment is very long, and the process needs to be repeated for each piece, which is time-consuming and laborious;

[0006] (2) Conventional clamping and alignment are all carried out on the machine tool, which leads to too long non-processing time of the parts, a corresponding increase in the time of the CNC milling process of the parts, and a longer manufacturing cycle of the product; and the utilization rate of the equipment is not high, and the economic benefits needs improvement
