Like huge revolving spare interior admission water ring is a vitals of guide mechanism in flow-through turbine; It and outer gate barrel and be distributed in the main body that stator between inside and outside ring sparger has been formed water distributor jointly; The machining accuracy in the hole of installation stator, the five equilibrium property in hole and hole all can influence the sealing of assembling rear guide vane and the flexibility of motion in the position in space.
Summary of the invention
The purpose of this invention is to provide a kind of easy to operate, machining accuracy is high, cost of manufacture is low a kind of method of utilizing gear-hobbing machine machining large revolving meber halving hole.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of method of utilizing gear-hobbing machine machining large revolving meber halving hole, this method is installed the boring unit head on gear-hobbing machine, utilize the boring unit head to process huge revolving spare halving hole, and the concrete steps of this method are:
1. the hobboing cutter head of a bed on the gear-hobbing machine is laid down, boring unit head support is installed in gear-hobbing machine head of a bed position;
2. on gear hobbing machine worktable, place some parallels high, equidistance, centering parallels of waiting; On parallels, place huge revolving spare, with huge revolving spare by the endoporus of having processed look for circle just, the upper surface levelling just;
3. after confirming the centering leveling,,, guarantee boring bar axis and halving hole dead in line in revolving meber spherical outside surface centering boring bar position according to the huge revolving spare halving hole pitch circle groove of vertical lathe portrayal;
4. utilize the boring unit head that halving hole is carried out roughing;
5. after confirming that roughing everywhere is qualified, carry out fine finishining again;
6. tool changing, the counter counter sink of scraping the halving hole back side.
The boring unit head is made up of milling cutter, boring bar, axial feed mechanism, variable-frequency motor, and the variable-frequency motor connecting axle is to delivering gear, and axial feed mechanism connects boring bar, the anterior milling cutter that connects of boring bar.
Compared with prior art, the invention has the beneficial effects as follows:
1, the high precision numerical control vertical turning and boring mill of original method employing involves great expense, and the present invention adopts gear-hobbing machine machining large revolving meber halving hole, has greatly reduced cost of manufacture.
2, the indexing accuracy of gear-hobbing machine is high, can guarantee the machining accuracy of machining large revolving meber halving hole.
Description of drawings
Fig. 1 is a kind of apparatus structure sketch map that utilizes the method for gear-hobbing machine machining large revolving meber halving hole;
Fig. 2 is the structural representation of boring unit head.
Among the figure: the 1-interior admission water ring 2-boring unit head 3-gear-hobbing machine sliding carriage 4-parallels 5-support 6-gear-hobbing machine 7-milling cutter 8-boring bar 9-axial feed 10-of mechanism variable-frequency motor
The specific embodiment
The inventive method is utilized the high performance of gear-hobbing machine indexing accuracy, and lathe is transformed, and makes it process stator axis hole on the high interior admission water ring of precision 1.
16 stator axis holes that with the processing dimension are Φ 155H7 below are example, narrate the concrete steps of this method:
1. the hobboing cutter head of a bed on the gear-hobbing machine is laid down, the boring unit head is installed, boring unit head 2 and support 5 are installed in gear-hobbing machine head of a bed position, boring unit head 2 is installed on the support 5, and support 5 is installed on the gear-hobbing machine sliding carriage 3; Boring unit head support 5 is weldments, and machined behind the elimination welding stress guarantees that angle is 60 ° to the milling head lower margin between face and gear-hobbing machine column guide rail closing.Wire cutting machine tool capable of using is made high accuracy, large scale angular templet, and the angular error after guaranteeing to process is 10 " in.
2. eight equal parts is placed eight blocks of contour pad iron 4, parallels 4 upper surface levellings, the iron filings or the burr of peace and quiet interior admission water ring 1 bottom surface on gear hobbing machine worktable; Interior admission water ring 1 is placed on the parallels 4, with interior admission water ring 1 by the endoporus of having processed look for the circle just, the upper surface levelling just; The centering ERROR CONTROL is in 0.05mm.
3. after confirming the centering leveling, with reference to the stator axis hole pitch circle groove of vertical lathe portrayal, interior admission water ring 1 spherical outside surface centering boring bar position guarantees that the boring bar axis overlaps with the stator axially bored line.Specific practice is: at first in the boring bar axis hole, adorn higher top of a precision, start lathe, through moving forward and backward the gear-hobbing machine mountain, moving up and down sliding carriage 3, make top aligning stator axis hole pitch circle groove; On boring bar, place the magnetic support amesdial then, gauge outfit is beaten on interior admission water ring 1 spherical outside surface.Rotate boring bar, beat the manufactured SR2100.6 sphere of vertical lathe with amesdial, boring bar return circle in, amesdial is beated and will be controlled in the 0.03mm.At this moment, the boring bar axis is vertical with interior admission water ring 1 spherical outside surface, the boring bar axis promptly is the normal of sphere, and also promptly: the boring bar axis overlaps with the stator axially bored line.
4. utilize the boring unit head that the stator axis hole is carried out roughing;
5. after confirming that roughing everywhere is qualified, carry out fine finishining again;
6. tool changing, the counter counter sink of scraping the stator axis hole back side.
The boring unit head is made up of milling cutter 7, boring bar 8, axial feed mechanism 9, variable-frequency motor 10, and variable-frequency motor 10 drives axial feed mechanism 9, drives boring bar 8 feeds through axial feed mechanism 9, the anterior milling cutter 7 that connects of boring bar.The boring unit head is the commercially available prod.
