Abstract
The invention relates to a method for coaxially processing the large and small axial holes of rotator, to confirm the coaxial degree. Wherein, it comprises that first processing large axial hole, then inserting boring main axle 2 into small axial hole to fine the jump of large axial hole via gage 3 at the part that boring axle is near to the end; via said jump. Increasing the boring main axle for 1/2 jump. The invention uses gage to test the jump Delth, to increase 1/2 Delth of main axle, with simple process and low cost.
Description
Technical field
The present invention relates to a kind of hydrogenerator rotary wheel body big and small axle holes coaxially processing method.
Background technology
Web is the core part of whose turbine generator group, and whether the axiality of web size axis hole directly has influence in blade assembling and the unit operation blade rotation flexible.Certain web size axis hole degree of depth is 793mm, and big or small axis hole axiality 0.02mm is when processing axis hole, because the rigidity of machine tool chief axis tends to occur big-eared phenomenon when deep hole processing on boring machine.
Summary of the invention
The objective of the invention is to for overcoming the critical technological point of hydrogenerator rotary wheel body big and small axle holes coaxially processing, a kind of hydrogenerator rotary wheel body big and small axle holes coaxially processing method is provided, overcome big-eared phenomenon of web size axis hole deep hole machining, guarantee the axiality of big or small axis hole.
Goal of the invention of the present invention is achieved through the following technical solutions: rotary wheel body big and small axle holes coaxially processing method, be used to guarantee the axiality of web size axis hole, its procedure of processing is: process big axis hole earlier, then boring spindle is stretched into little axis hole, find out the jerk value of big axis hole at the boring proximal head place frame dial gauge that is coupling, according to jerk value with artificial 1/2nd jerk values that rise of boring spindle.
The present invention uses dial gauge to measure the be coupling jerk value of the big axis hole in proximal head place of boring, and with artificial 1/2nd jerk values that rise of boring spindle, processing method is simple, practical, saves processing cost according to jerk value.
Description of drawings
Fig. 1 a uses dial gauge to find out the jerk value of big axis hole
Artificial 1/2nd jerk values that rise of Fig. 1 b boring spindle
Among the figure, 1-web, 2-main shaft, 3-dial gauge, Δ h-jerk value.
The specific embodiment
Further describe technical scheme of the present invention below in conjunction with accompanying drawing: as Fig. 1 a, comprise web 1, boring spindle 2, rotary wheel body big and small axle holes coaxially processing method is: process big axis hole earlier, then boring spindle is stretched into little axis hole, at the boring proximal head place frame dial gauge 3 that is coupling, find out the jerk value Δ h of big axis hole by dial gauge 3.
As Fig. 1 b, find out the jerk value Δ h of big axis hole after, according to jerk value Δ h with artificial 1/2nd jerk values, i.e. the Δ h/2 of rising of boring spindle.
Claims (1)
1, rotary wheel body big and small axle holes coaxially processing method, be used to guarantee the axiality of web size axis hole, it is characterized in that its procedure of processing is: process big axis hole earlier, then boring spindle is stretched into little axis hole, find out the jerk value of big axis hole at the boring proximal head place frame dial gauge that is coupling, according to jerk value with artificial 1/2nd jerk values that rise of boring spindle.
