Abstract
The utility model discloses a gland seal clearance adjustment measurement card, including micrometer measurement handle, and set up the blade that main chi card and body have at the fixed graduated flask top of both handles, another fixed graduated flask top sets up the chi card that moves about that main chi card and body have, installs on the blade, and two main chi cards correspond the end symmetry and set up the fixture of measuring foot card combination. The device is suitable for measuring gland rings with different specifications, and the two bodies can be decomposed and used independently, and the measurement precision can reach 0.01%.
Description
The utility model relates to a kind of Gland Clearance in Steam Turbine adjusting gear, is that card is measured in the adjustment of a kind of labyrinth clearance specifically.
The patent No. of known domestic patent gazette is in the disclosed technology of ZL93204086.1 " labyrinth clearance adjustment measurement mechanism ", and it is installed on the measuring table by measuring dial framework and dial gauge, forms with mold by measuring.To from the turbine steam seal conduit, take out through the labyrinth ring sampling silicon cream of compression moulding during measurement, insert and measure in the mold,, realize that the labyrinth clearance is measured and adjustment with the thickness of dial gauge measurement silicon cream.Through use finding that the every measurement of the first once must be taken out the labyrinth ring of having suppressed the silicon cream of sampling from the packing groove, take on the measuring table and just can finish measurement, for the whether qualified labyrinth ring in gap, all need take off measurement like this, again away from the scene.Therefore, surveying work is more loaded down with trivial details, time-consuming takes a lot of work, and is not easy to improve the adjustment efficiency of measurement; It two is labyrinth rings for different size, measurement mold that must the preparation different size, and therefore, along with the difference of type, the difference of manufacturing, the specification of labyrinth ring is very many also, so this measurement mechanism just can not be satisfied the demand.
The purpose of this utility model provides a kind of working site that both had been applicable to and measures, and can satisfy the labyrinth clearance adjustment that the labyrinth ring of different size is measured again and measure card.
The technical solution of the utility model, finish by following measure: card is measured in the labyrinth clearance adjustment, comprise the miking handle, its handle top installs and measures jig, and measure jig by adopting two miking handles, wherein a fixedly graduated cylinder top of measuring handle is provided with on main scale card and the body and has blade, another fixedly graduated cylinder top of measuring handle is provided with the chi card that moves about that has on main scale card and the body, and the chi card that moves about is installed on the blade, cooperate by the location of the lock-button on it, be equipped with navigation button and sounding rod lock fit on each main scale card, and two main scale card the same sides are arranged with the measurement pin card formation of evagination.
This is novel to have following advantage:
1, card is measured in this labyrinth clearance adjustment, because of having adopted mobile main scale card device, can satisfy the labyrinth ring that is applicable to different size and measure, and makes it reach the function that a jig is used more, and its measuring accuracy can reach 0.01mm.
2, this measurement card has adopted two split structures to form.Can insert labyrinth ring to level after the combination of two bodies and carry out clearance measurement; To also can satisfy independently measurement function after the decomposition of two bodies.
3, measure jig main scale card outboard end wherein and also disposed the dovetail rule card, can insert labyrinth ring and measure the common measurement that realizes two cards on the base, measure 2 adjusted values of a labyrinth ring simultaneously, make its surveying work convenient, quick.
Embodiment is described further below in conjunction with accompanying drawing.
Fig. 1 measures the card structure view for the labyrinth clearance adjustment.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the partial view of another structure embodiment of Fig. 1.
Fig. 4 measures another embodiment of card for Fig. 1.
By Fig. 1, shown in 2, card is measured in the labyrinth clearance adjustment, comprise and measure handle and measure jig two parts composition, two existing standard milscale handles 1 of its employing and 1 ', two handles 1 and 1 ' fixedly graduated cylinder 2 and 2 ' on have the scale of indicating axial displacement, its measure jig by wherein one fixedly the top of graduated cylinder 2 fixedly install the blade 9 that has on main scale card 3 and the body, and being provided with conduit 10, the middle part of blade 9 sees Fig. 2, the main scale card 3 of corresponding blade 9 one sides is provided with measures pin card 6, the sounding rod of measuring in the handle 15 passes main scale card 3, and can be along telescopic displacement on the main scale card 3; Another looking somebody up and down handle 1 ' fixedly graduated cylinder 2 ' the top fixedly install main scale card 3 ' and the trough-shaped body that has of body chi card 7 that moves about, main scale card 3 ' a side be provided with measure pin card 6 ', make its sounding rod 5 of utilize measuring handle 1 ' interior ' be installed in the conduit 10 of blade 9, make the chi card 7 that moves about in blade 9 conduits 10, carry out displacement, main scale card 3 and 3 ' measurement pin card 6 and 6 ' be symmetrical in measure handle 1 and 1 ' the same side, cooperate with the location, side of blade 9, main scale card 3 and 3 ' on be provided with respectively navigation button 4 and 4 ', with sounding rod 5 and 5 ' lock fit, measurement pin card 6 by main scale card 3 and blade 9 and main scale card 3 ' measurement pin card 6 ' and the chi card 7 that moves about cooperate the measurement jig of forming.
Fig. 3 shows the local embodiment that another structure of card is measured in the labyrinth clearance adjustment.It is to be provided with dovetail groove chi card 11 by the outside butt end of a main scale card 3 wherein on above-mentioned integrally-built basis, and two main scale cards 3 and main scale card 3 ' between blade 9 bodies on also be provided with and hold out against butterfly screw 12, be used for two main scale cards 3 and 3 ' two when measuring pin cards 6 and 6 ' ride over ring and colluding workplace, directly hold out against the end face that colludes at ring by holding out against butterfly screw 12.
Fig. 4 has adopted the main scale card 3 of Fig. 1 structure and the blade 9 that body has, and pipe box 13 1 ends of electronic digital indicator fixedly are housed in blade 9 lower ends, and the sounding rod 5 that the other end is introduced has draw ring 15, and pipe box 13 1 sides have a digital display window 14 to constitute.Can have equal measurement effect with milscale.And by the displacement of directly reading sounding rod 5 on the digital display window 14, its measuring accuracy is 0.01mm.
