Abstract
The utility model discloses a device for measuring wave degree of a tubular seat flange face of a hydroelectric generating set. The device for measuring the wave degree of the tubular seat flange face of the hydroelectric generating set comprises a magnetic base and an inside micrometer. The inside micrometer comprises a rod body and a micrometer head connected with the rod body, and the rod body can be connected to the magnetic base. By arranging the magnetic base at the front end of the rod body of the inside micrometer, the inside micrometer can be placed on an inclined surface, does not easily topple and fall and can be absorbed on the flange face under the action of magnetic force, especially on a vertical flange face. The device is matched with a theodolite for use, and the high-precision wave degree can be measured. The device for measuring the wave degree of the tubular seat flange face of the hydroelectric generating set can be used for measurement of the wave degree of flange faces of parts of tubular seats of hydroelectric generating sets.
Description
Technical field
The utility model relates to a kind of survey instrument, particularly relates to a kind of measurement mechanism of hydraulic generator unit cast seat flange face wave degree.
Background technology
In electromechanical installation, generally the flange face to the large scale stressed member all has technical requirement, and the main evaluating of this technical requirement is a wave degree.The flange face wave degree is the stress of decision large-size components, is the important parameter that guarantees installation quality.
The flange face wave degree of in the past measuring the large scale stressed member generally adopts transit to cooperate Steel Ruler.At the reference field of the setting transit of having put on the shelf; And an end of Steel Ruler is fixed on the flange face of unit under test; And the adjustment Steel Ruler is vertical with flange face, on transit, reads scale, and the difference of the relative reading of each point then is the wave degree of this flange face on the flange face.Yet; Because the end face of Steel Ruler is very little; Measure and be difficult to keep Steel Ruler vertical with flange face; And the minimum scale value on the Steel Ruler is 0.5mm; So measuring accuracy can only reach 0.5mm; For some high-precision wave degree requirements, require to be no more than 0.12mm/m like the tubular seat wave degree of part producer Bulb Turbine Units, whole flange face wave degree is no more than
0.2mm.This moment, the measuring accuracy of Steel Ruler can not meet the demands.Micrometer inside caliper can replace Steel Ruler can reach this measuring accuracy; The micrometer inside caliper measuring accuracy reaches 0.01mm; But micrometer inside caliper is difficult to directly fixing on tested surface, therefore micrometer inside caliper is fixed on the magnet base, and magnet base can directly be attached on the flange face; But measure while adjusting, convenient and swift.
The utility model content
The technical matters that the utility model will solve provides a kind of measurement mechanism of hydraulic generator unit cast seat flange face wave degree.
The utility model solves the technical scheme that its technical matters adopted: a kind of measurement mechanism of hydraulic generator unit cast seat flange face wave degree; Comprise magnet base and micrometer inside caliper; Said micrometer inside caliper is provided with shaft and gauge head, and said shaft can be attached to magnet base.
Further as the improvement of the utility model technical scheme, also comprise the joint with upper surface and lower surface, said upper surface is connected with shaft, and the lower surface is connected with magnet base.
Further as the improvement of the utility model technical scheme, said shaft is threaded with the upper surface, and said magnet base is threaded with the lower surface.
The beneficial effect of the utility model: the utility model is provided with magnet base through the shaft front end at micrometer inside caliper; Can make micrometer inside caliper be placed on the dip plane and be not easy topples over; And can under the effect of magnetic force, be adsorbed on the flange face; Especially vertical flange face, the utility model cooperate transit to use, and can record high-precision wave degree.
The utility model can be used in the flange face wave degree measurement of each parts of hydraulic generator unit cast seat.
