Description
Technical field
The present invention relates to field of machining, and in particular to rotor of steam turbo generator shaft coupling is to group pin-and-hole processing side
Method.
Background technology
Have on rotor of steam turbo generator shaft coupling one group with turbine rotor to group pin-and-hole, by pin-and-hole load join
Connecting bolt is by generator amature and turbine rotor to group, conjunction.To ensure smooth, the essence of generator amature and turbine rotor
Really assemble, the dimensional tolerance, position degree and surface roughness to pin-and-hole have all done strict requirements, this group of diameter of pin-and-hole is public
Difference is general within according to 0.05mm, position degree within 0.05-0.10mm, surface roughness Ra more than 1.6.
To ensure the machining accuracy of pin-and-hole, the conventional machining process of specific purpose tool drill jig is had been used up in the past.In recent years, respectively
Generator manufacturing firm needs not turning off the new product for sending different size in a short time, to adapt to market needs.New product
Rotor coupling pin-and-hole size is different, needs to obtain through refining various sizes of drill jig if using traditional handicraft.Because of drill jig manufacture
Cycle is long, and manufacturing expense is higher, certainly will take the generator product entirety manufacturing cycle, and improves cost of goods manufactured, special
Be not the product urgent for some durations, the design and manufacture of drill jig can even turn into one of restriction manufacturing schedule it is unfavorable because
Element.
The content of the invention
In order to solve the above problems, the present invention provides a kind of simple to operate, easy to process, and can guarantee that the processing matter of workpiece
Amount and machining accuracy, improve production efficiency reduce the rotor of steam turbo generator shaft coupling of production cost to group pin-and-hole processing side
Method.
Rotor of steam turbo generator shaft coupling of the present invention is comprised the following steps to group using pin-and-hole processing method：
The first step, heavy boring, by each pin-and-hole elder generation's heavy boring to desired size；
Second step, half right boring carries out once half right boring, and diameter tolerance control is within 0.05mm after each pin hole boring；
3rd step, measurement position degree measures each pin-and-hole to beeline, pin-and-hole internal diameter between shaft coupling seam, each pin-and-hole, record
Measured value；
4th step, amendment, according to measurement data, global analysis pin-and-hole offsets relative to the position of seam, adjusts coordinate, then carry out one
Secondary right boring, mono- section of 30-40mm is bored in each pin-and-hole leading portion, can meet the measurement of inside micrometer, and each hole is measured again to only
Mouthful, between each hole, the internal diameter of hole, whether the coordinate after checking adjustment adjustment accurate, it is such as not all right adjust again, measurement, until each measurement
Numerical value meets position degree requirement, i.e., each hole internal diameter dimensional discrepancy within 0.05mm, beeline, each pin between each pin-and-hole
Hole to shaft coupling seam deviation within 0.05mm；
5th step, right boring：Complete last right boring；
6th step, checks, after right boring completion, more than measurement each numerical value, judges that position degree, pin-and-hole internal diameter size are qualified again
Afterwards, record data.
The present invention is simple to operate, easy to process, and can guarantee that the crudy and machining accuracy of workpiece, improves production effect
Rate, reduces production cost.
