Description
Technical field
The utility model relates to the machining equipment field, relates in particular to a kind of deep hole boring processing unit (plant) that is used for the Steam Turbine's Main Vaper Valve valve body.
Background technology
Supercritical pressure turbine stop valve valve body material is ZG1Cr10MoWVNiN, and the not only sticking but also hard difficulty of processing of this material is big, and its processing difficulties is the deep and long hole processing of valve body; Its Kongzui small-bore reaches 340mm, the general 2500mm of length, and conventional processing method generally adopts the repeatedly processing method of reaming of holing again earlier; Process knife bar arm length; Vibration is big, and working (machining) efficiency is low, and machining accuracy is difficult for guaranteeing.
Summary of the invention
The purpose of the utility model provides a kind of deep hole boring processing unit (plant) that is used for the Steam Turbine's Main Vaper Valve valve body, realizes that whole deep and long hole processes at one time, and the deep and long hole core can integral body take off, and satisfies requirement on machining accuracy.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
The deep hole boring processing unit (plant) that is used for the Steam Turbine's Main Vaper Valve valve body; It is characterized in that comprise boring instrument, pedestal, guide rail, buncher, bearing block, front rack and tail-bracket, pedestal is provided with guide rail; Be provided with buncher and bearing block on the guide rail successively; Link to each other through power transmission shaft between buncher and the bearing block, power transmission shaft is connected with the boring instrument, is provided with front rack and tail-bracket between boring instrument and the pedestal successively.
Said boring instrument comprises boring bar, cutter head and blade, and cutter head is located at the end of boring bar, and blade along the circumferential direction evenly is arranged on the cutter head, and adjacent knife blades is provided with by positive sword, anti-sword at interval.
Said front rack is provided with oil filler point.
Prior art is compared; The beneficial effect of the utility model is: apparatus structure is simple, and low cost of manufacture can realize that the whole deep and long hole of Steam Turbine's Main Vaper Valve valve body processes at one time; Processing back deep and long hole core can integral body take off; Satisfy requirement on machining accuracy, production efficiency significantly improves, and the converted products quality is good.

The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
See Fig. 1; It is the deep hole boring processing unit (plant) example structure sketch map that the utility model is used for the Steam Turbine's Main Vaper Valve valve body; Comprise boring instrument 1, pedestal 2, guide rail 3, buncher 4, bearing block 5, front rack 6 and tail-bracket 7, pedestal 2 is provided with guide rail 3, is provided with buncher 4 and bearing block 5 on the guide rail 3 successively; Link to each other through power transmission shaft 8 between buncher 4 and the bearing block 5; Power transmission shaft 8 is connected with boring instrument 1 forward, is provided with front rack 6 and tail-bracket 7 between boring instrument 1 and the pedestal 2 successively, and front rack 6 is provided with oil filler point 9.
See Fig. 2, Fig. 3, boring instrument 1 comprises boring bar 10, cutter head 11 and blade 12, and cutter head 11 is located at the end of boring bar 10, and blade 12 along the circumferential direction evenly is arranged on the cutter head 11, and adjacent knife blades 12 is provided with by positive sword, anti-sword at interval, can produce iron filings in small, broken bits.
During the work of this device, first workpiece 13 with Steam Turbine's Main Vaper Valve valve body blank is placed on the workbench 14 before the pedestal 2, and front rack 6 is fitted with workpiece 13 machined surfaces; Cutting oil is injected by oil filler point 9; Flow out along the slit between front rack 6 and the boring bar 10, realize that boring instrument 1 moves axially at the drive lower edge guide rail 3 of bearing block 5 and buncher 4 to the cooling of boring instrument 1 and lubricated; In the middle of boring bar 10, form solid hole core 15; Cutting oil is carried iron filings secretly through boring bar 10 and power transmission shaft 8, is discharged by the chip-removal hole on the power transmission shaft 8 16, realizes uninterrupted chip removal in the boring processing process of big diameter and deep slotted hole.
