Abstract
The utility model relates to a propeller pitch measuring instrument which includes a screw vertical shaft which is provided with an upper cone seat and a lower cone seat. The propeller pitch measuring instrument is characterized in that the screw vertical shaft is sleeved with a seat sleeve which is connected with a cantilever ruler above the upper cone seat; the cantilever ruler is perpendicular to the screw vertical shaft and drives the seat sleeve to rotate along the screw vertical shaft; the lower edge of the seat sleeve is provided with an angle pointer; an angle disc is arranged below the seat sleeve; the cantilever ruler is provided with a slide block which slides back and forth along the cantilever ruler; and the slide block is provided with a measuring needle which moves up and down along the axis of the screw vertical shaft. The propeller pitch measuring instrument is simple in structure, is low in cost, is accurate in parameter measurement, and is rapid and light.
Description
Technical field
The utility model relates to pitchometer, especially a kind of airscrew pitch measuring instrument.
Background technology
Hanging clamp screw propeller after new system or repairing must carry out the measurement of standard pitch, judges whether to reach the designing requirement of canonical parameter with it.Boats and ships are unavoidable in long-term navigation process unexpected state occurs, cause blade usually deform, damaged, tear and the bad defective such as curling.It is main that present hanging clamp propeller material is selected aldary, and the screw propeller after damage also is convenient to repair, therefore, corresponding ship survey requirement, pitch measurement is a kind of normality sex work.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of airscrew pitch measuring instrument for the above-mentioned state of the art, and it is simple in structure, measurement is convenient and accurately.
the utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of airscrew pitch measuring instrument, comprise that one is arranged with the screw mandrel vertical pivot of epicone seat and lower cone seat, it is characterized in that: described screw mandrel vertical pivot be positioned at the epicone seat above be arranged with the cover for seat that is connected with cantilever chi, described cantilever chi is perpendicular to the screw mandrel vertical pivot and can drive cover for seat and rotate along the screw mandrel vertical pivot, the lower edge of described cover for seat is provided with an angle indicator, the below of described cover for seat is provided with an angle scale, be provided with a slide block that can slidably reciprocate along cantilever chi on described cantilever chi, be provided with a metering pin that can move up and down along the axis of screw mandrel vertical pivot on described slide block.
As improvement, described epicone seat and lower cone seat are relative position to be installed, and under the taper ratio of epicone seat, the tapering of cone seat is large.
As improvement, described angle indicator be tilted down and the orientation angle dish on numeral.
As improvement, the head of described metering pin is arranged to needle point shape.
compared with prior art, the utility model has the advantage of: because the lower edge of described cover for seat is provided with an angle indicator, the below of cover for seat is provided with an angle scale, and angle indicator is tilted down and is directed to numeral on angle scale, this structural design is the reading angular parameter easily, and be provided with a slide block that can slidably reciprocate along cantilever chi on described cantilever chi, and also being provided with one on slide block can be along the axis of screw mandrel vertical pivot metering pin up or down, this structure can be convenient to measure the different radii position and with the variation of Radius differing heights, this utility model is not only simple in structure, and cost is low, light and fast and measurement parameter are accurate.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
as shown in Figure 1, a kind of airscrew pitch measuring instrument, comprise that one is arranged with epicone seat 2 and lower screw mandrel vertical pivot 1 of boring seat 3, under the taper ratio of epicone seat 2, the large and epicone seat 2 of the tapering of cone seat 3 and lower cone seat 3 are relative position installation, screw mandrel vertical pivot 1 be positioned at epicone seat 2 above be arranged with the cover for seat 12 that is connected with strip cantilever chi 5, cantilever chi 5 is perpendicular to screw mandrel vertical pivot 1 and can drive cover for seat 12 along 1 rotation of screw mandrel vertical pivot, the lower edge of cover for seat 12 is provided with an angle indicator 8, and also be provided with an angle scale 4 below cover for seat 12, angle indicator 8 is tilted down and is directed to numeral on angle scale 4, cantilever chi 5 has also driven the rotation of the angle indicator 8 on cover for seat 12 when rotating, thereby can be according to the data variation on angle scale 4 and the reading angular parameter, be provided with a slide block 6 that can slidably reciprocate along cantilever chi 5 on cantilever chi 5, and a metering pin 7 that can move up and down along the axis of screw mandrel vertical pivot 1 also is installed on slide block 6, the head of metering pin 7 downwards and be arranged to needle point shape.
When measuring pitch, screw propeller 11 is lifted and flatly is positioned between epicone seat 2 and lower cone seat 3, and make as much as possible the dead in line of axis and the screw mandrel vertical pivot 1 of screw propeller 11, lock nut 9 by angle scale 4 belows fixes screw propeller 11 with coordinating of screw mandrel vertical pivot 1, makes screw propeller 11 be in relatively firm state; The sheathed cover for seat 12 that is connected with cantilever chi 5 again, rotate the angle-data on cantilever chi 5 reading angular dishes 4, slip by the slide block 6 on cantilever chi 5, make metering pin 7 be in the position of different radii, and the variation that moves up and down to satisfy blade 10 differing heights on Radius by metering pin 7, thereby can accurately measure the pitch of screw propeller 11.
