Description
Technical Field
The utility model relates to a supporting detection tool field of gas turbine blade, in particular to gas turbine allies oneself with guide vane throat and detects anchor clamps more.
Background
The Gas Turbine (Gas Turbine) is an internal combustion type power machine which takes continuously flowing Gas as a working medium to drive an impeller to rotate at a high speed and converts the energy of fuel into useful work, and is a rotary impeller type heat engine. At present, gas turbines are roughly divided into large gas turbines and small gas turbines by volume, wherein the large gas turbines include power generation gas turbines and ship gas turbines, and the small gas turbines include aviation gas turbines, but the blades of the gas turbines are all in a severe working environment, and extremely high requirements are imposed on the quality and dimensional accuracy of the blades.
At present, a gas turbine multi-connected guide blade 8 shown in fig. 1 needs to detect the distance between blade throats, and at present, workers generally find detection positions by visual inspection, and the deviation of the detection positions is large, so that the blade throat detection error is large, and the precision is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a gas turbine allies oneself with guide vane throat and detects anchor clamps more, its advantage is in the precision that further improves the detection, reduces the error.
The above technical purpose of the present invention can be achieved by the following technical solutions:
the throat detection clamp for the multi-connected guide blade of the gas turbine is installed on the multi-connected guide blade and comprises a detection tool body, wherein a detection groove is formed in the detection tool body, and a first positioning column, a second positioning column, a third positioning column, a fourth positioning column, a fifth positioning column and a sixth positioning column are arranged on the detection tool body.
Further, the detection groove is arranged along the length direction of the detection tool body, and the detection groove is arc-shaped.
Furthermore, a positioning point a1, a positioning point a2, a positioning point A3, a positioning point B1, a positioning point B2 and a positioning point C1 are marked on the multi-connected guide vane, and the first positioning column, the second positioning column, the third positioning column, the fourth positioning column, the fifth positioning column and the sixth positioning column respectively correspond to the six positioning points.
To sum up, the utility model discloses following beneficial effect has:
1. the throat detection clamp for the multi-connected guide blade of the gas turbine is accurately fixed on the blade to be detected in a six-point contact positioning mode, gaps are reserved between the two sides of the detection tool body and the outline of the blade at the moment, and a worker inserts the stop-go gauge into the throat from the gaps on the two sides and the detection groove respectively, so that the throat can be quickly and accurately detected;
2. when the blade is detected, a worker only needs to install the detection clamp and insert the go-no go gauge, and the operation is simple.

In the drawing, 1, a gauge body; 11. a detection tank; 2. a first positioning column; 3. a second positioning column; 4. a third positioning column; 5. a positioning column IV; 6. a fifth positioning column; 7. a positioning column six; 8. and (4) multiple guide vanes.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
Example 1: a throat detection clamp for a multi-connected guide vane 8 of a gas turbine is shown in figure 2 and comprises a detection tool body 1, wherein the detection tool body 1 is installed on the multi-connected guide vane 8 to be detected (shown in figure 3), and auxiliary workers carry out detection work.
As shown in fig. 1, positioning point a1, positioning point a2, positioning point A3, positioning point B1, positioning point B2 and positioning point C1 are marked on the multi-connected guide blade 8, wherein positioning point B1 and positioning point B2 are located on the outer contour of the multi-connected guide blade 8, positioning point a1, positioning point a2, positioning point A3 and positioning point C1 are all located on the blade, and positioning point a1 and positioning point a2 are located on the same blade.
Referring to fig. 1 and 2, a first positioning column 2, a second positioning column 3, a third positioning column 4, a fourth positioning column 5, a fifth positioning column 6 and a sixth positioning column 7 are arranged on the checking fixture body 1, the first positioning column 2 corresponds to a positioning point a1, the second positioning column 3 corresponds to a positioning point a2, the third positioning column 4 corresponds to a positioning point A3, the fourth positioning column 5 corresponds to a positioning point B1, the fifth positioning column 6 corresponds to a positioning point B2, and the sixth positioning column 7 corresponds to a positioning point C1. When detecting, each reference column contacts corresponding setpoint, examines utensil body 1 and adopts the mode of six point location to accomplish accurate positioning, reduces the error.
As shown in fig. 2, the detection groove 11 is arranged along the length direction of the detection tool body 1, the detection groove 11 is arc-shaped, and the radian of the detection groove 11 is matched with the outer contour radian of the multi-connected guide blade 8. When the multi-connected guide vane works, a worker inserts the go-no go gauge into the throat of the multi-connected guide vane 8 through the detection groove 11, and the detection groove 11 plays a role in accurately determining a detection position.
The specific implementation process comprises the following steps: when detecting, at first will examine a body and install the guide vane that ally oneself with that waits to detect, six reference columns contact corresponding setpoint respectively this moment, and the body is examined in accurate positioning, reduces the error because examining a body position deviation leads to. At the moment, gaps are reserved between the two sides of the checking fixture body and the outline of the blade, workers insert the stop gauges with different specifications into the throat from the gaps on the two sides and the detection groove respectively, the detection position of the throat is accurately determined, and the detection work can be accurately and quickly completed.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
