In order to guarantee that the measurement and positioning device in the general measuring instrument places steadily on tested high-pressure compressor wheel disc, mass screw can be set, described mass screw is installed on the crossbeam, and its installation site placement location of tested high-pressure compressor wheel disc when measuring is corresponding.
In order better to realize goal of the invention, following version that relevant member in the above-mentioned general measuring instrument and parts are preferred:
1, the two ends of described location-plate are separately installed with first register pin.
2, the described first measurement assembly comprises that the 4th shows folder, first sleeve that is connected with the 4th table folder and be inserted into the first interior measuring staff of first sleeve, and the described second measurement assembly comprises the 5th table folder, presss from both sides second sleeve that is connected and be inserted into the second interior measuring staff of second sleeve with the 5th table.
3, the cross section of the described first table folder be " door shape " structure, and a side wall lower ends be extended with lug, the two side lower section of described " door " is separately installed with second register pin, the 3rd register pin, described lug is provided with the dial gauge mounting hole.
4, the cross section of the described second table folder is " door shape " structure, and the two side lower section of described " door " is respectively arranged with the dial gauge mounting hole.
The general measuring instrument use-pattern of high-pressure compressor wheel disc tongue-and-groove described in the utility model: breakout box is inserted in the tested high-pressure compressor wheel disc dove-tail form tongue-and-groove, by standard component (the standard component structure is seen Figure 12 and Figure 13) dial gauge of installing on the measurement and positioning device is checked, then the measurement and positioning device is placed on the tested high-pressure compressor wheel disc, by breakout box is transferred out in position that tongue-and-groove is surveyed and measure.
The general measuring instrument of high-pressure compressor wheel disc tongue-and-groove described in the utility model has following beneficial effect:
