Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The utility model is specifically related to a kind of engine crankshaft corner measurement apparatus, realizes with simple structure, accurately
The measurement angle data of bent axle 8 simultaneously intuitively shows that device detachable maintaining is convenient with cloud atlas, and service life is high.As shown in figure 1, passing through
The different angle position of glory disk 7 rotated with bent axle 8 sends different color of light, using color sensor 4 to 7 turns of glory disk
The color of light sampling analysis irradiated during dynamic, judges to send the color of light, with reference to default different face in computer 5
The corresponding different angle-datas of color, calculate the corner situation of analysis bent axle 8, and the situation for having Radial Perturbation to bent axle 8 is carried out
The amendment of the angle data of bent axle 8, obtains the accurate angle data of bent axle 8, judges the time of ignition of engine 1, while can be through D/A
Converter and A/D converter are handled the corner situation that bent axle 8 is shown with cloud atlas.
Glory disk 7 is used to be detachably fixed and is connected with bent axle 8, is rotated with bent axle 8, the different annular angles of glory disk 7
Degree is to that should have different color of light, and same color of light in the radial direction is identical, and the color of light foundation three primary colors on glory disk 7 are not
Same radix is mixed, successively along the annular spread of glory disk 7, and the color of light on glory disk 7 vertically its end face can irradiate, in face
Coloured light does not dissipate when irradiating.Three primary colors red, green, blue has 255 radixes, and the achievable color of light of glory disk 7 has 255 × 255
The color of × 255 kinds of light, the corresponding outer corner measurement precision of bent axle 8 is 360/（255×255×255）Degree.Wherein, the corner of bent axle 8
Measurement accuracy it is also relevant with the operating efficiency of computer 5 with color sensor 4.
In the corresponding annular radius region of ring shaped color light of glory disk 7, colored is set to pass perpendicular to the end face of glory disk 7
Sensor 4, color sensor 4 is provided with suitable distance with glory disk 7, and color sensor 4 is removable by mounting frame for sensor 3
Unload and be fixedly connected on stand 2, color sensor 4 is connected with computer 5, in the different angles of the glory disk 7 that is stored with computer 5
The rotational angle data of correspondence glory disk 7.
As shown in Fig. 2 two dividing plates 9 of the end face of glory disk 7 are provided perpendicular between sensor probe 6 and glory disk 7,
Two dividing plates 9, which use to be detachably fixed, to be connected on stand 2, is produced gap between two dividing plates 9, is adopted for color sensor 4
Collection glory disk 7 goes to the solid color light of some angular illumination, further prevents the diverging of color of light and influences the corner of bent axle 8 to survey
Amount.
If Radial Perturbation in the rotation process of bent axle 8, it can be gone out by rotating a kind of color of light in one week angle in bent axle 8
Existing number of times, by correcting numerical value, is modified to disturbance situation discriminatory analysis to the corner situation of bent axle 8, obtains accurate
The angle data of bent axle 8.
As shown in figure 3, glory disk 7 is rotated with bent axle 8, prized vertical its end face irradiation face of CD 7 in rotation process
Coloured light, color sensor 4 collects the color that glory disk 7 turns to the light irradiated during with 6 correspondence position of sensor probe, warp
D/A converter, data signal is converted to by the color analog signal of light, and the mixed radix of three primary colors red, green, blue, judgement is adopted
Light color and the corresponding relation of the angle of glory disk 7 in the color collected, with the glory disk 7 of the memory storage of computer 5, to glory disk 7
Rotational angle calculate, obtain the angle data of bent axle 8.By A/D converter, the three primary colours blended data of color is switched into specific face
Color, can be shown the situation of the corner of bent axle 8 collected with cloud atlas.Meanwhile, angle position correspondence is selected on glory disk 7
Color be the time of ignition of engine 1 demarcation, after the angle data of bent axle 8 is collected, for analyze judge that engine 1 is lighted a fire
Moment.
The utility model goes out the color of different three primary colors radix mixing using vertical irradiation in the different annular angles of glory disk
Light, glory disk calculates bent axle with crank rotation, the rotation situation of the color of light on color sensor collection analysis glory disk
Corner.When bent axle has Radial Perturbation, it can be modified by correction factor crank angle data and obtain accurately crank angle
Data.According to the color of light in the selected a certain annular angle of the corresponding glory disk of engine igniting time, engine is judged
Time of ignition.While crank angle situation, the processing that may be calculated machine is intuitively shown with cloud atlas.The utility model is simple in construction,
Detachable maintaining is convenient, and measurement apparatus service life is long, can be achieved to thanks for your hospitality bent axle crank angle DATA REASONING during emotionally condition, right
Crank angle data are intuitively shown with cloud atlas.
The utility model can also judge disturbance situation when bent axle has certain Radial Perturbation and correct bent axle
Angle data, is more accurately measured crank angle, and less demanding to the mounting distance of sensor and glory disk, is improved
The service life of measurement apparatus.
