Abstract
Hole distance measuring device on a kind of wind-driven generator, including main scale, one end of main scale is fixed with fixed ruler pawl, main scale is equipped with vernier scale pawl, the ruler pawl end of fixed ruler pawl and vernier scale pawl is equipped with crossover sub, and the crossover sub is equipped with mounting hole and bolt hole, fixing bolt is equipped in bolt hole.Hole distance measuring device on a kind of wind-driven generator described in the utility model, overall structure is simple, to vernier caliper clawed end portions by being simply transformed, vernier caliper measurement aperture of the measurement range in two meters can just be allowed to be less than 10mm once, the distance between two distant apertures, easy to operate, accuracy is high.
Description
Technical field：
The utility model belongs to generator small-bore drilling ranging field, is specifically related to pitch-row on a kind of wind-driven generator
Measuring device.
Background technology：
Have many drillings on the casing of the generator of wind energy, these drillings often all very littles, diameter mostly all 10mm with
Under, and casing itself is larger, and fuselage is longer, although volume is big, precise requirements are higher, and common tape measure is used for surveying
Accuracy of measurement is not achieved, although and can be reached with existing vernier caliper precision, since bore diameter is too small, existing card
The clawed end portions of ruler can not be put into hole greatly very much, can not be measured, and can put the slide calliper rule in hole into since main scale is long
Degree is inadequate, can not measure.
Utility model content：
Above-mentioned in order to overcome the shortcomings of, the utility model provides hole distance measuring device on a kind of wind-driven generator.
The utility model solves technical solution used by its technical problem：
Hole distance measuring device on a kind of wind-driven generator, including main scale, one end of main scale is fixed with fixed ruler pawl, main scale
Equipped with vernier scale pawl, the ruler pawl end of fixed ruler pawl and vernier scale pawl is equipped with crossover sub, and the crossover sub is equipped with solid
Determine hole and bolt hole, fixing bolt to be equipped in bolt hole.
The mounting hole runs through the upper and lower surface of crossover sub, and spiro keyhole position is on the side wall of crossover sub.
One end triangular structure of the mounting hole, the other end are square structures.
The bolt hole is through the side wall of crossover sub and the rectangular side wall of mounting hole.
Due to using technical solution as described above, the utility model has following superiority：
Hole distance measuring device on a kind of wind-driven generator described in the utility model, overall structure is simple, to vernier caliper
Clawed end portions are by being simply transformed, it will be able to vernier caliper measurement aperture of the measurement range in two meters be allowed to be less than 10mm mono-
Under, the distance between distant two apertures are easy to operate, and accuracy is high.

Specific embodiment：
The utility model can be explained in more detail by example below, open the purpose of this utility model is intended to protect
All changes and improvements in the scope of the utility model, the utility model are not limited to the following examples；
Hole distance measuring device on a kind of wind-driven generator with reference to described in attached drawing, including main scale 1, one end of main scale 1 is fixed
Equipped with fixed ruler pawl 2, main scale 1 is equipped with vernier scale pawl 3, and the ruler pawl end 7 of fixed ruler pawl 2 and vernier scale pawl 3 is equipped with conversion and connects
First 4, the crossover sub 4 is equipped with mounting hole 8 and bolt hole 9, and fixing bolt 5 is equipped in bolt hole 9.
The mounting hole 8 runs through the upper and lower surface of crossover sub 4, and bolt hole 9 is located on the side wall of crossover sub 4.
One end triangular structure of the mounting hole 8, the other end are square structures.
The bolt hole 9 is through the side wall of crossover sub 4 and the rectangular side wall of mounting hole 8.
Ruler pawl end 7 is inserted into mounting hole 8, is close to rectangular side wall, the diameter of pin 6 is selected according to pore size, than
If aperture is 8mm, then the round pin of 6mm diameters can be selected, pin 9 is inserted into mounting hole 8, close to triangular structure
One end, why be designed as triangular structure, be consider have better package to pin 9, if pin is circular configuration, that
When being close to the hole of square structure, an only line contact, one side fixation will not be too strong, to pin after on the other hand screwing
Son generates extruding, may influence precision, pin 6 and ruler pawl end 7 are fixed on crossover sub 4 i.e. by rotary fixing screw bolt 5
Can, pin, which is inserted into, treats the aperture i.e. readable of gaging hole, and the distance between two apertures are equal to measured length and subtract two pins
Radius.
Part is not stated in more than content carefully as the prior art, therefore does not run business into particular one and states.
