Abstract
The utility model provides a measuring device of a turbine rotor seal ring groove, which can solves problems in the prior art, realize multi-angle measurement and guarantee accuracy. The measuring device comprises a measuring clamping plate and a turbine rotor, and is characterized by further comprising a stepping motor and a frame, wherein a turbine head of the turbine rotor is top-mounted in the frame; a worm end portion of the turbine rotor is connected with the stepping motor through a shaft coupling; and the stepping motor is installed on a fixing block, and after installation, the turbine rotor and the stepping motor are on the same shaft axis.
Description
Technical field
The utility model relates to the technical field that turbine is made, and is specially a kind of measurement mechanism of turbine rotor closure gasket groove.
Background technology
In the turbine rotor process, one technique is arranged for cutting the turbine rotor seal groove, technological requirement is cut a groove that width is certain for the position in the deviation range of distance last item end face certain distance, the groove position measurement instrument that adopts is a kind of measurement clamp, the time hand-held clamp of measuring of measuring, with 2 (drift face and no-go gage face) vertical closure gasket grooves that inject turbine rotor measuring clamp, it is the size conforms technological requirement that feel does not have hard crowded sense.But there is a defective in this structure, owing to adopting hand-held the measurement, if can not guarantee that measuring clamp vertically injects, will cause measuring inaccurate, and if carry out multiangular measurement, must be repeatedly will measure clamp and vertically inject the closure gasket groove of turbine rotor, and must guarantee it all is vertical reeves each time, like this in the practical operation, and be not easy to accomplish, efficient is lower, therefore, accuracy rate can not guarantee.
Summary of the invention
For the problems referred to above, the utility model provides a kind of measurement mechanism of turbine rotor closure gasket groove, can solve the problem that prior art exists, and realizes multiangular measurement, and can guarantee accuracy rate.
Its technical scheme is such, it comprises measures clamp, turbine rotor, it is characterized in that: it also comprises stepper motor, frame, the turbine head of described turbine rotor is mounted on described frame, the scroll bar end of described turbine rotor is connected in described stepper motor by shaft coupling, described stepper motor is installed on fixed block, and after the installation, described turbine rotor and described stepper motor are positioned on the same axial line.
The utility model adopts after the said structure, stepper motor can drive turbine rotor by shaft coupling and rotate, like this, when needs are measured the turbine rotor closure gasket groove, directly inject in the closure gasket groove as long as will measure clamp, then stepper motor drives turbine rotor and turns an angle the continuation measurement, so just realize multiangular measurement, guaranteed the preparation rate.
Description of drawings
Fig. 1 structure of the present utility model;
Whether accurately Fig. 2 measures position that clamp measures turbine rotor closure gasket groove structural representation.
Embodiment
See that Fig. 1 the utility model comprises measurement clamp 1, turbine rotor 2, it also comprises stepper motor 3, frame 4, the turbine head of turbine rotor 2 is mounted on frame 4, the scroll bar end of turbine rotor 2 is connected in stepper motor 3 by shaft coupling 5, stepper motor 3 is installed on fixed block 6, after the installation, turbine rotor 2 is positioned on the same axial line with stepper motor 3.The side that meeting Fig. 2 measures clamp 1 is drift 7, opposite side is no-go gage face 8, end both sides of measuring clamp 1 are with the outer flange 9 of Fixed width, the width of the outer flange 9 of Fixed width equals the width A of closure gasket groove, the outer flange of the both sides of the other end of measurement clamp 1 is divided into the outer flange 10 of drift, the outer flange 11 of no-go gage, the bee-line of outer flange 10 inner faces flange 9 inner faces outside Fixed width of drift is last item end face 12 certain distance D and lower limit of variation b sum, and the bee-line of outer flange 11 inner faces flange 9 inner faces outside Fixed width of no-go gage is last item end face 12 certain distance D and deviation upper limit c sum.
When needs are measured turbine rotor 2 closure gasket groove, drift face, no-go gage face are measured turbine rotor after having cut turbine rotor 2 closure gasket grooves respectively, the outer flange 9 of Fixed width is stuck in the closure gasket groove, then the outer flange 10 of drift, the outer flange 11 of no-go gage are contacted with last item end face 12, if there is hard extruding sense in when contact or can not normally contacts, judge that then the position of seal groove is inaccurate; If without firmly pushing sense and can normally contacting, judge that then the position of seal groove is accurate.Then stepper motor drive turbine rotor turns an angle, and continues to measure, and has so just realized multiangular measurement, has guaranteed the preparation rate.
