Abstract
The utility model relates to a kind of frame-type stator blade two ends round drill jig, described stator blade two ends round to be coordinated with drill bit by the drill jig be placed on drilling machine and processes, described drill jig is a C font frame plate, is made up of upper bushing plate, middle connecting plate and lower molded lines heel installing plate; The two ends of described upper bushing plate are provided with some boring corresponding with stator blade two ends round and some compression screws for compressing stator blade, and are all inlaid with drill bushing in each boring; The inner surface of described molded lines heel installing plate installs molded lines heel, and this molded lines heel and upper bushing plate form one and hold the die cavity that stator blade embeds.The utility model has the advantage of: surplus stator blade overall length being left 5mm, by placing this drill jig on the workbench of drilling machine, then processing is coordinated by drill bit, last gap and the blade head factory being milled out round again by milling machine, it is easy to process, and effectively improve production efficiency, this kind of mould may be used for the round processing of N220-4 level, N132-3 level, Z552-7 level stator blade.
Description
Technical field
The utility model relates to a kind of machining equipment, and more particularly, the utility model relates to a kind of frame-type stator blade two ends round drill jig that can improve stator blade production efficiency.
Background technology
Dividing plate inside stator blade i.e. steam turbine, it is fixing in the cylinder, a lot of stator blade is had in a cylinder, a stator blade and a movable vane composition one-level, superheated steam enters first stage stator blades sheet from porthole, and stator blade water conservancy diversion steam enters moving vane, drive rotor, be mechanical energy by thermal power transfer, the steam through the first order enters second level stator blade and movable vane again, and principle is equally main is exactly the effect playing water conservancy diversion steam.
As shown in Figure 1, the edge of stator blade 1 has some for hard-wired round 11 of casting, and each round 11 all has gap, direct slotting cutter milling efficiency is too low, be all add related overall length with Linear cut to cut off together with chamfering at present, although the capability and performance of product is good, production efficiency is low.
Therefore a kind of hole drilling die that can enhance productivity of research and development is badly in need of imperative.Through retrieval related documents, do not find the same or analogous technical scheme with the utility model.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of frame-type stator blade two ends round drill jig that can enhance productivity.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of frame-type stator blade two ends round drill jig, described stator blade two ends round to be coordinated with drill bit by the drill jig be placed on drilling machine and processes, its innovative point is: described drill jig is a C font frame plate, is made up of upper bushing plate, middle connecting plate and lower molded lines heel installing plate; The two ends of described upper bushing plate are provided with some boring corresponding with stator blade two ends round and some compression screws for compressing stator blade, and are all inlaid with drill bushing in each boring; The inner surface of described molded lines heel installing plate installs molded lines heel, and this molded lines heel and upper bushing plate form one and hold the die cavity that stator blade embeds.
Further, described compression screw has two, is symmetricly set on the two ends of bushing plate respectively.
The utility model has the advantage of:
1. stator blade overall length is left the surplus of 5mm, by placing this drill jig on the workbench of drilling machine, then processing is coordinated by drill bit, last gap and the vane overall length being milled out round again by milling machine, it is easy to process, and effectively improve production efficiency, this kind of mould may be used for N220-4 level, N132-3 level, Z552-7 level stator blade.
2. be inlaid with drill bushing in boring, this drill bushing has certralizing ability, has positioning action during boring descending to drill bit, and when dismantling rear replacing after drill bushing wearing and tearing;
3. compress screw and have two, be symmetricly set on the two ends of bushing plate respectively, its compressing structure is simple, and stator blade can be made to be pressed in drill jig.
Accompanying drawing explanation
Fig. 1 is the structural representation of stator blade.
Fig. 2 is the top view of a kind of frame-type stator blade two ends of the present utility model round drill jig.
Fig. 3 is the side view of a kind of frame-type stator blade two ends of the present utility model round drill jig.
Detailed description of the invention
Embodiment 1
For Z552-7 level stator blade in this example, as shown in Figure 1, Figure 2 and Figure 3, the utility model discloses a kind of frame-type stator blade two ends round drill jig, drilling machine coordinate with drill bit by boring film, round processing is carried out to stator blade 1 two ends,
Above-mentioned drill jig is a C font frame plate, is made up of upper bushing plate 21, middle connecting plate 22 and lower molded lines heel installing plate 23; The two ends of upper bushing plate 21 are provided with some boring corresponding with stator blade 1 two ends round 11 and some compression screws 28 for compressing stator blade, and are all inlaid with drill bushing 24 in each boring; The inner surface of molded lines heel installing plate 23 installs molded lines heel 25, and this molded lines heel 25 and upper bushing plate 21 form the die cavity 26 that an appearance stator blade embeds.
In the present embodiment, in order to make stator blade 1 be pressed in drill jig, compressing screw 28 has two, is symmetricly set on the two ends of bushing plate 21 respectively.
During use, first the molded lines heel 25 that the inner arc molded line with stator blade 1 coincide is fixed on the molded lines heel installing plate 23 of drill jig, then in the die cavity from side stator blade 1 being embedded in drill jig in 26, finally the drill jig assembled and stator blade are placed on the workbench of drilling machine, open drilling machine and process.
Claims (2)
1. a frame-type stator blade two ends round drill jig, described stator blade two ends round to be coordinated with drill bit by the drill jig be placed on drilling machine and processes, it is characterized in that: described drill jig is a C font frame plate, be made up of upper bushing plate, middle connecting plate and lower molded lines heel installing plate, the two ends of described upper bushing plate are provided with some boring corresponding with stator blade two ends round and some compression screws for compressing stator blade, and are all inlaid with drill bushing in each boring; The inner surface of described molded lines heel installing plate installs molded lines heel, and this molded lines heel and upper bushing plate form one and hold the die cavity that stator blade embeds.
