Embodiment Construction

[0021] specific implementation plan

[0022] Further description will be given below with reference to the accompanying drawings.

[0023] Such as figure 1 As shown, the "piano wire-photoelectric differential instrument" is mainly composed of a measuring base 1, a differential tube 2, a connecting body 3, and an edge finder 4. One end of the differential tube 2 is fixed on the measuring base 1, and its The other end passes through the coupling body 3 and the edge finder 4 . The above measuring seat 1 is square and adopts 45# quenching material. The bottom surface is provided with a "V" groove 5, which divides the bottom surface into two parts. These two parts are in contact with the surface to be tested. There is a circular boss 6 on the top. There is a blind hole 7 in the middle of the boss 6, which fits with the micrometer cylinder 2. , There are two screw holes on the side wall of the blind hole, and the screw holes are equipped with bolts, which are used for locking.

Abstract

The invention relates to a piano wire-photoelectric differential instrument, which is characterized in that: it mainly consists of a measuring seat, a differential cylinder, a connection body and an edge detector; one end of the differential cylinder is fixed on the measuring seat, while the other is connected with the edge detector through the connection body. The invention achieves the advantages of reasonable structure, high detection speed, high sensitivity, simple operation and high work efficiency.

Description

Technical field: [0001] The technology belongs to the detection field, and specifically relates to a piano wire-photoelectric differential instrument for precise detection of major components such as the concentricity of the major axis of the power equipment hydroelectric generator set of a hydropower station, and the parallelism of the rotor magnetic pole surface. Background technique: [0002] In the current hydraulic turbine equipment manufacturing industry, due to the large test object and limited test equipment, the piano wire-earphone test method is often used when testing the coaxiality of the large shaft and the parallelism of the rotor magnetic pole surface. However, this method usually has low detection accuracy due to the different hearing of the inspectors and the different current of the earphones, and the highest accuracy is above 0.02mm. In addition, the sensitivity of this method is not high, which affects the efficiency of the detection work. . Invention c...
