Abstract
The utility model provides a steam turbine semiring drainage hole drill plate, which relates to a tool of drilling a hole and solves the problems that the processing charge is high, an inclined hole and a vertical hole can not cross because the deviation easily occurs, and the product quality is seriously influenced in the prior art. One end of a vertical drill plate (3) of the steam turbine semiring drainage hole drill plate is fixedly connected with the lower end of an end face drill plate (1), and the other end is fixedly connected with the lower end of a side plate (8), an inclined hole (1-1) is arranged on the end face drill plate (1), an inclined hole drill bush (2) is embedded on the inner wall of the inclined hole (1-1), a vertical hole (3-1) is arranged on the vertical drill plate (3), a vertical drill bush (4) is embedded on the inner wall of the vertical hole (3-1), a hole (6-1) is arranged on the side plate (6), and a compression screw (5) is arranged in the hole (6-1). The steam turbine semiring drainage hole drill plate saves the processing charge, causes the deviation of the inclined hole and the vertical hole of a steam turbine semiring drainage hole to be less than 0.10 mm, and improves the product quality.
Description
Technical field
The utility model belongs to a kind of instrument of drawbore.
Background technology
The steam turbine semi-ring belongs to large-scale lopps parts, diameter is more than 4 meters, its outer shroud is a taper seat, interior ring is the face of cylinder, in its endface position the inclination angle being arranged is 30 ° of inclined hole 20-φ 46 * 334, and the hole of 20-φ 46 * 133 is also arranged on the interior ring face of cylinder of corresponding same radiation, intersect in ring body in two holes.Traditional diamond-making technique is to use the angular milling head on the large-sized gantry milling machine, earlier the inclined hole end face is milled a plane with slotting cutter, and then with bit drills inclined hole and upright opening.Processing charges height in the prior art, and deviation appears easily, cause inclined hole and upright opening not to intersect, have a strong impact on product quality.
The utility model content
The purpose of this utility model is in order to solve processing charges height in the prior art, and occurs deviation easily and cause inclined hole and upright opening not to intersect, and has a strong impact on the problem of product quality and then a kind of steam turbine semi-ring weep hole drill jig is provided.The utility model is made up of end face bushing plate 1, inclined hole drill bushing 2, vertical bushing plate 3, vertical drill bushing 4, housing screw 5 and side plate 6; One end of vertical bushing plate 3 and the lower end of end face bushing plate 1 are affixed, the other end of vertical bushing plate 3 and the lower end of side plate 6 are affixed, on end face bushing plate 1, be provided with inclined hole 1-1, inclined hole drill bushing 2 is set on the inwall of inclined hole 1-1, on vertical bushing plate 3, be provided with straight hole 3-1, vertical drill bushing 4 is set on the inwall of straight hole 3-1, is provided with hole 6-1 on side plate 6, and housing screw 5 is installed in the 6-1 of hole.
The utlity model has following beneficial effect: the utility model has been saved processing charges, and the deviation that makes steam turbine semi-ring weep hole inclined hole after the drilling and upright opening has improved product quality less than 0.10mm.
Description of drawings
Fig. 1 is overall structure master's pseudosection of the present utility model, and Fig. 2 is the left view of Fig. 1.
The specific embodiment
The specific embodiment one: in conjunction with Fig. 1 and Fig. 2 present embodiment is described, present embodiment is made up of end face bushing plate 1, inclined hole drill bushing 2, vertical bushing plate 3, vertical drill bushing 4, housing screw 5 and side plate 6; One end of vertical bushing plate 3 and the lower end of end face bushing plate 1 are affixed, the other end of vertical bushing plate 3 and the lower end of side plate 6 are affixed, on end face bushing plate 1, be provided with inclined hole 1-1, inclined hole drill bushing 2 is set on the inwall of inclined hole 1-1, on vertical bushing plate 3, be provided with straight hole 3-1, vertical drill bushing 4 is set on the inwall of straight hole 3-1, is provided with hole 6-1 on side plate 6, and housing screw 5 is installed in the 6-1 of hole; On end face bushing plate 1, be provided with centering window 1-2.During processing vapor turbine semi-ring weep hole, can earlier the steam turbine semi-ring be placed on the contour pad case, on the end face of steam turbine semi-ring and the endoporus face of cylinder, draw the weep hole center line then, drill jig is placed on the steam turbine semi-ring, end face bushing plate and steam turbine semi-ring upper surface are adjacent to, then breach about the centering window is alignd with the weep hole center line, tightening housing screw fixes drill jig and steam turbine semi-ring, start full universal drill and earlier drill bit is imported inclined hole drill bushing rat holing, again drill bit is imported vertical drill bushing and bore upright opening, bore the back and guarantee that two holes are crossing in hemizonid.
