Abstract
The utility model relates to an excircle line-marking tool for a rotating propeller type turbine blade, which is characterized by mainly comprising a bracket inserted in a rotating wheel body. The upper end of the bracket is provided with a horizontal bar, the end of the horizontal bar is sleeved with a telescopic rod, the telescopic rod is provided with a screw, the external end of the telescopic rod is fixedly provided with a vertical bar in a downward direction, and the end of the vertical bar is sleeved with a line-marking pen. The line-marking pen can rotate along with the surface of the blade so as to finally achieve the line-marking purpose. Therefore, the utility model can greatly reduce the machining allowance of the blade, shorten the processing time, and reduce the cost of using the machine tool. Moreover, the utility model can realize more accurate follow-up treatment on the blade, and facilitate the future static equilibrium experiment.
Description
Technical field
The utility model belongs to hydraulic turbine manufacturing technology field, particularly relates to a kind of Kaplan turbine blade cylindrical line frock.
Background technology
The blade excircle dimension of Kaplan turbine is to be that the size of runner envelope matches with runner.If blade and runner envelope excesssive gap will cause hydraulic loss, reduce runner efficiency, if the gap is too small, then may rub with runner envelope, damage, therefore need process, reach best effects so that runner blade cooperates with runner envelope to the runner blade cylindrical.And the excircle dimension of runner blade is relevant with a lot of sizes, wherein is made up of a lot of dimension chains, and itself all has the size range of oneself these dimension chains, also has cumulative errors during assembling.Because the size of blade cylindrical has the several factors influence, therefore all needs to leave a lot of allowance at the blade cylindrical in the past,, size processes inadequately in case taking place.This will cause the excessive situation of allowance might occur when machined, waste machining time.
Summary of the invention
The utility model provides a kind of simple in structure, easy to use, Kaplan turbine blade cylindrical line frock of increasing work efficiency for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of Kaplan turbine blade cylindrical line frock, it is characterized in that: this line frock mainly comprises the support that is inserted in the web, the upper end of support is equipped with horizontal cross bar, the end suit expansion link of horizontal cross bar, expansion link is provided with dog screw, the expansion link outer end is the vertical bar of fixed installation downwards, and vertically the end of bar is set with bow pen.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly made a support, this support can be rotated along the web center, a horizontal cross bar and vertical bar are set on support, and horizontal cross bar and vertical bar employing adjustable structure, enlarged the scope of application of the present utility model, in addition when line, vertically the bow pen on the bar can finally reach the purpose of line along the surperficial servo-actuated of blade.Therefore the utility model can significantly reduce the machining allowance of blade, shortens process time, reduces the cost that uses lathe, and can carry out subsequent treatment to blade more accurately, for the experiment of static balance is later on provided convenience.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the utility model user mode structural representation.
Among the figure: 1, web; 1-1, blade; 2, support; 3, horizontal cross bar; 4, expansion link; 5, dog screw; 6, vertical bar; 7, bow pen.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, now exemplify following examples, and conjunction with figs. is described in detail as follows: see also Fig. 1 and Fig. 2, a kind of Kaplan turbine blade cylindrical line frock, this line frock mainly comprises the support 2 that is inserted in the web 1, the upper end of support 2 is equipped with horizontal cross bar 3, the end suit expansion link 4 of horizontal cross bar 3, expansion link 4 is provided with dog screw 5, expansion link 4 outer ends are the vertical bar 6 of fixed installation downwards, vertically the end of bar 6 is set with bow pen 7, and bow pen 7 can carry out servo-actuated up and down according to the curved surface of blade.
User mode: support 2 is installed on the web 1, and suit expansion link 4 on the horizontal cross bar 3 of support 2 can be mediated according to different runner blade diameters like this, as adjust suitable after, be fixed with dog screw 5.Be set with the bow pen 7 with the servo-actuated of blade curved surface on the vertical bar 6 of support 2, this is that telescopic joint can be reconciled automatically according to the height of curved surface, thereby reaches the purpose of line because blade 1-1 is a space curved surface.After adjusting installation, swinging mounting, the uniform line that just can draw on runner blade comes.Therefore the utility model can significantly reduce the machining allowance of blade, shortens process time, reduces the cost that uses lathe, and can carry out subsequent treatment to blade more accurately, for the experiment of static balance is later on provided convenience.
