Description
TECHNICAL FIELD
[0001] The utility model relates to turbine shell detection equipment field, especially a turbine shell gauge. BACKGROUND
[0002] In prior art, when the position degree of the threaded hole at the turbine shell air inlet and the threaded hole at the exhaust port is detected, the hole position detection of multiple threaded holes cannot be carried out simultaneously, which is low in efficiency, and therefore, the structure of the threaded hole at the turbine shell air inlet and the threaded hole at the exhaust port needs to be improved so that multiple hole positions can be detected simultaneously, which is higher in working efficiency and can complete the detection work at one time.

[0010] In order to ensure the accuracy of detection, the calibration of the reference surface is required before detection, and the calibration of the reference surface is realized by the table gauge belt. The value of the table gauge belt is observed to determine whether the horizontal pressing structure pushes the turbine shell air inlet to the position.

[0015] The horizontal threaded push rod can be rotated to move left and right.
[0016] As a further optimization of the utility model, the bottom surface of the detection table top is provided with telescopic support legs at four corners.

[0021] 1、In this scheme, first of all, the turbine hole of the turbine shell is placed in the guide sleeve type turbine hole positioning structure, then the air inlet of the turbine shell is pushed to the horizontal hole detection mechanism by the horizontal pressing structure, then the position degree of the screw hole at the air inlet of the turbine shell is detected by the horizontal hole detection mechanism, and the position degree of the screw hole at the exhaust port of the turbine shell is detected by the inclined hole position detection mechanism.
[0022] 2、The elastic downward pressing part in the shape of "X" can more easily place the turbine shell in the guide sleeve type turbine hole positioning structure.
[0023] 3、In order to ensure the accuracy of detection, therefore, the calibration of the reference surface needs to be carried out before detection, and the calibration of the reference surface is realized by the tape gage, and whether the air inlet of the turbine shell is pushed to the right position by the horizontal pressing structure can be determined by observing the value of the tape gage.
[0024] 4、Before the inclined hole position detection, the reference surface calibration of the plane where the exhaust port of the turbine shell is located also needs to be carried out, and this calibration work is also realized by the tape gage, and whether the plane where the exhaust port of the turbine shell is located is in place can be determined by observing the value of the tape gage.
