Description

A kind of measurement apparatus of the blast tube area of gas turbine static blade
Technical field
It the utility model is related to a kind of measurement apparatus, and in particular to a kind of blast tube area of gas turbine static blade Measurement apparatus.
Background technology
At present, gas turbine is widely used in power industry, the blast tube between static blade on gas turbine Size directly influences the efficiency of gas turbine complete machine.Therefore in manufacturing and repairing gas turbine work, its static leaf The measurement of the blast tube area of piece just seems extremely important.Because the blast tube shape between static blade is trapezoidal, and And need the venturi position for measuring area very big in the inside of blast tube, measurement difficulty;The survey of blast tube area in the past Amount leans on common slide calliper rule, micrometer even three coordinates to carry out mostly, and these metering systems are inaccurate and unstable and repeated Property it is poor, manufacture and repair gas turbine precision do not improve all the time.
Utility model content
The utility model provides a kind of measurement apparatus of the blast tube area of gas turbine static blade, can accurately survey Blast tube area is measured, metering system is stable and reproducible, improves production efficiency.
The technical solution of the utility model is as follows:A kind of measurement dress of the blast tube area of gas turbine static blade Put, including mainboard, bushing, guide pin bushing, positioning pipe, guide pillar, transmission rod, connecting plate, gauge head, spring, support bar, side locating piece and hundred Dividing table, the mainboard is provided with two bushings, two guide pin bushings and a support bar, and the positioning pipe is arranged in the bushing, The front end of the positioning pipe is provided with chuck;The guide pillar is vertically set on one end of the connecting plate, and the transmission rod is vertically set Put on the connecting plate, the gauge head is arranged on the other end of the connecting plate;The guide pillar is placed in the guide pin bushing, institute State transmission rod to be placed in the positioning pipe, the spring is provided between the transmission rod and the positioning pipe;The mainboard Side is provided with side locating piece;The dial gauge is placed in the bushing and contacted with the transmission rod.
The beneficial effects of the utility model are:The utility model can accurately measure blast tube area, and metering system is steady It is fixed and reproducible, improve production efficiency.
Brief description of the drawings
Fig. 1 is the measurement apparatus front view of the blast tube area of gas turbine static blade;
Fig. 2 is the measurement apparatus side view of the blast tube area of gas turbine static blade;
Fig. 3 is the measurement apparatus working state schematic representation of the blast tube area of gas turbine static blade.
Embodiment
As shown in Figure 1, 2, a kind of measurement apparatus of the blast tube area of gas turbine static blade, including mainboard 1, lining Set 2, guide pin bushing 3, positioning pipe 4, guide pillar 5, transmission rod 6, connecting plate 7, gauge head 8, spring 9, support bar 10, side locating piece 12 and percentage Table 11, the mainboard 1 are provided with two bushings, 2, two guide pin bushings 3 and a support bar 10, and the positioning pipe 4 is arranged on the lining In set 2, the front end of the positioning pipe 4 is provided with chuck;The guide pillar 5 is vertically set on one end of the connecting plate 7, the power transmission Bar 6 is vertically set on the connecting plate 7, and the gauge head 8 is arranged on the other end of the connecting plate 7 vertically downward;It is described to lead Post 5 is placed in the guide pin bushing 3, and the transmission rod 6 is placed in the positioning pipe 4, the transmission rod 6 and the positioning pipe 4 Between be provided with the spring 9;The side of the mainboard 1 is provided with side locating piece 12;The dial gauge 11 is placed in the bushing 2 Contacted with the transmission rod 6.
As shown in figure 3, the course of work is as follows:According to qualified blast tube shape processing criterion model, according to the standard sample Two dial gauges 11 are zeroed by plate;The chuck of two positioning pipes 4 is stuck on the exhaust side of first static blade 13, side positioning Block 12 is leaned against on the supramarginal plate of gas turbine, and support bar 10 is placed on the adjacent back side middle part of second static blade 14; Gauge head 8 is pressed on second back side of static blade 14 by spring 9 by transmission rod 6, and guide pillar 5 and connecting plate 7 ensure that transmission rod 6 It will not be deflected with gauge head 8 and gauge head 8 is located at the venturi position of blast tube;Record the reading of dial gauge 11, dial gauge 11 Rotate counterclockwise numerical value is negative, and dial gauge 11 turns clockwise numerical value as just;After record reading compared with standard jig just The precision of blast tube area can be calculated.
