Abstract
The invention provides a special blade profile gap detector which improves the prior digital-display detection instrument, can favorably suit the high-precision rapid high-efficiency detection requirements for detecting a small profile gap, replaces the prior manual three-coordinate measuring method and a general feeler detection mode and has the advantages of low production cost, high precision, rapid and flexible operation, small size, high detection efficiency and easy popularization. The special blade profile gap detector comprises a base, a displacement sensor and a guiding device, wherein the guiding device is fixed on the base and connected with the displacement sensor by a fixed block. The special blade profile gap detector is characterized by also comprising a conical feeler whichis connected with the guiding device by an L-shaped girder, and the contact head of the displacement sensor contacts with the positioning surface of the conical feeler.
Description
(1) technical field
The present invention relates to the turbine blade checkout equipment, be specially special blade profile gap detector.
(2) background technology
Turbine blade finished product and the less gap of blade forging profile printing opacity are very little, and be usually about 0.2～3mm, most of between 0.5～1.5mm.China's blade profile size detection mainly contains dual mode at present, one is because blade is spatial warping face, the artificial three-dimensional coordinates measurement of the many employings of finished product blade profile, it is difficult that the blade location is adjusted, and data read many, treatment capacity is large, efficient is lower, and cost is large, is difficult to adapt to the many kinds of blade, short run, the quick manufacturing technique requirent that detects of seriation.Its two forging profile printing opacity gap is many, adopt special framework measuring tool and the large envelope dedicated test of profile model by smooth clearance gauge sample plate and detect workpiece gap and obtain (blade forging), this metering system precision is low, need a plurality of clearance gauge multiple measurement, clearance gauge width measure Accuracy is larger, be difficult to guarantee that a blade has tens grades of cross section molded line usually, each shelves needs again to detect gap, a plurality of position.Profile testing amount is extremely heavy, and working strength is large.
(3) summary of the invention
For the problems referred to above, the invention provides special blade profile gap detector, it shows that to existing numeral detecting instrument improves, can better adapt to the little gap detection of profile, the detection of high precision, quickness and high efficiency needs, and replaces present artificial three-dimensional coordinates measurement method and conventional clearance gauge detection mode.This tool production cost is low, and precision is high, and simple operation is flexible, and volume is little, and detection efficiency is high, is easy to promote.
Its technical scheme is such: it comprises pedestal, displacement transducer, guide piece, described guide piece is fixed on the described pedestal, described displacement transducer is connected with described guide piece by fixed block, it is characterized in that: it also comprises the circular cone clearance gauge, it is connected with described guide piece by " L " ellbeam, and described displacement transducer contact head contacts with the locating surface of described circular cone clearance gauge.
It is further characterized in that:
Described circular cone clearance gauge is the circular cone acicular texture; Described guide piece comprises pilot sleeve and spring, described pilot sleeve is sleeved on the minor face outside of described " L " ellbeam, described spring is inner at described pilot sleeve, and the one end axially is connected with the minor face of described " L " ellbeam, and the other end directly is fixed on the described pedestal; Described displacement transducer afterbody be sleeved on described fixed block inner and can and fixed block between slippage occurs, described fixed block is fixed on described pilot sleeve lateral wall.
The present invention also is provided with reference location device, and it comprises a benchmaring platform, has a benchmark alignment grooves on the described benchmaring platform, described benchmark contraposition groove depth 3mm.
Using blade profile gap digital display of the present invention to detect Vernier clearance gage detects blade profile printing opacity gap, its accuracy of detection is high, simple operation has improved detection efficiency flexibly, greatly, and its volume is little, only need existing numeral to show that detecting instrument improves, production cost is low, is easy to promote.

(5) embodiment
See Fig. 2, Fig. 3, the blade profile gap digital display detects Vernier clearance gage and comprises pedestal 6, displacement transducer 5, guide piece and circular cone clearance gauge 1, guide piece is fixed on the pedestal 6, displacement transducer 5 is connected by fixed block 11 and guide piece, circular cone clearance gauge 1 is the circular cone acicular texture, it is connected with guide piece by one " L " ellbeam 2, and the surface of contact of displacement transducer 5 contacts with the locating surface of circular cone clearance gauge 1; Guide piece comprises pilot sleeve 3 and spring 4 suits, and pilot sleeve 3 is sleeved on the minor face outside of " L " ellbeam 2, and spring 4 is in pilot sleeve 3 inside, and an end of spring 4 axially is connected with the minor face of " L " ellbeam 2, and the other end directly is fixed on its pedestal 6; Displacement transducer 5 afterbodys are sleeved on fixed block 11 inside, and displacement transducer 5 can generating horizontal displacement with respect to fixed block 11, and fixed block 11 is fixed on pilot sleeve 3 lateral walls; The present invention also is provided with reference location device, and it comprises benchmaring platform 7, has a benchmark alignment grooves 8 at benchmaring platform 7, described benchmark contraposition groove depth 3mm.
When special blade profile gap detector of the present invention is carried out origin reference location, such as Fig. 2, pedestal 7 is placed on the benchmaring platform 7, circular cone clearance gauge lower end is inserted in the benchmark alignment grooves 8 and is contacted with bottom land, this moment, the circular cone clearance gauge moved 3mm (benchmark contraposition groove depth) downward vertically, displacement transducer should move 3mm vertically upward with respect to circular cone clearance gauge locating surface, can carry out the benchmark adjustment if any deviation.
When carrying out the blade profile gap detection with special blade profile gap detector, see Fig. 4, Fig. 5, its pedestal 6 places on the large envelope model 9 of circular arc, the workplace of circular cone clearance gauge 1 and blade profile to be detected 10 are fitted, the horizontal long leg of pressing " L " ellbeam divides, then in the vertical slit of inserting blade profile 10 to be detected and the large envelope model 9 of circular arc of circular cone clearance gauge 1 until large envelope model 9 applyings of the locating surface of circular cone clearance gauge 1 and circular arc, in this process, spring 4 in the guide piece is to lower compression, identical vertically upward displacement has occured with displacement transducer 5 with respect to circular cone clearance gauge 1 in pilot sleeve 3, level displacement has to the right also occured with respect to circular cone clearance gauge 1 in simultaneous displacement sensor 5, and this horizontal shift is the blade profile gap of required detection and exports data by displacement transducer.
