Abstract
The utility model discloses a polar coordinates tire profile measurer comprising a measuring instrument and a computer. The polar coordinates tire profile measurer is characterized in that the measuring instrument is mainly composed of an angle sensor, a shaft, a bearing, a crank arm, and a range finding sensor, the shaft is fixedly connected with the bearing, one end of the crank arm is connected with the shaft, the other end of the crank arm is connected with the range finding sensor, the crank arm can be rotated about a fixed axis, and the angle sensor is arranged on the other end of the shaft. The range finding sensor scans the profile of a tire according to a sequence of tire bead, tire crown, and tire bead such that the polar coordinates tire profile measurer obtains a profile curve graph of the tire. The polar coordinates tire profile measurer has characteristics of simple structure, non-contact measurement, convenience and practicality, and high measurement precision.
Description
Technical field
The utility model relates to measurement mechanism, specifically a kind of polar coordinates tyre contour outline measuring instrument.
Background technology
In the development and production of tire, conventionally need to the profile of tire be measured and be analyzed and researched, the most direct method of one is that tire is dissected, and observes its transversal section; Another kind method is that use two or three-dimensional coordinates measurement instrument are measured, two or the probe of three-dimensional coordinates measurement instrument move along tyre contour outline migration, measure the volume coordinate of each point of tyre contour outline and input computing machine, computing machine synthesizes the pattern of tyre contour outline according to the coordinate of input.
It is comparatively coarse that tire postmortem method seems, measuring accuracy is poor; Two or three-dimensional coordinates measurement instrument measuring accuracy high, but surveying instrument is expensive, measurement range is limited, measures impracticable to tyre contour outline.
Measure requirement in order to meet all size model tyre contour outline, Chinese patent CN201083492 and CN201322614 disclose respectively " tire outline measuring instrument " and " easy tyre contour outline measuring set ", they are all to use planar linkage mechanism, between connecting rod, hinge fills mutually, front bar and support hinge dress, foot piece, with probe, is recorded the information of mechanism kinematic according to probe migration tyre contour outline, finally according to these information, tyre contour outline is restored again.But decorate manyly due to the hinge in these two kinds of measuring methods, in record and the process of processing mechanism information, can introduce unavoidably multiple error, make the contour curve data precision of measurement not high.
Summary of the invention
The limitation of measuring tyre contour outline for prior art, the utility model discloses a kind of simple in structure, economical and practical polar coordinates tyre contour outline measuring instrument.
The technical scheme that realizes the utility model object is:
A kind of polar coordinates tyre contour outline measuring instrument, comprise measuring instrument, unlike the prior art: measuring instrument is mainly made up of angular transducer, axle, bearing, connecting lever and distance measuring sensor, axle is fixedly connected with bearing, connecting lever one end is connected with axle, the other end is connected with distance measuring sensor, and connecting lever can rotate around fixed axis, and angular transducer is arranged on the other end of axle.
Described connecting lever is square connecting lever or round connecting lever.
Described distance measuring sensor is laser range sensor.
Advantage of the present utility model: the utility model is the outline from tyre bead-crown-tyre bead scanning tire according to laser range sensor, obtains tire outline curve map, has simple in structure, non-contact measurement, the feature that convenient and practical, measuring accuracy is high.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model polar coordinates tyre contour outline measuring instrument;
Fig. 2 is the measuring principle figure of the utility model polar coordinates tyre contour outline measuring instrument.
In figure: 1. angular transducer 2. axle 3. bearing 4. connecting lever 5. laser range sensor 6. tires
Embodiment
Referring to Fig. 1, a kind of polar coordinates tyre contour outline of the utility model measuring instrument is made up of angular transducer 1, axle 2, bearing 3, connecting lever 4, laser range sensor 5.The right-hand member of connecting lever 4 is connected with the left end of axle 2, and axle 2 is arranged on fixing bearing 3, and connecting lever 4 can rotate around fixed axis, and the right part of axle 2 is provided with angular transducer 1, can measure the angle of rotation.Connecting lever 4 left ends are provided with laser range sensor 5, can measure laser range sensor 5 to the distance between surface of tyre.
With reference to Fig. 2, when measurement, first adjust the relative position of measuring instrument and tire 6, the laser beam of laser range sensor 5 is in the tire section that needs to measure, rotating connecting lever 4 makes laser range sensor 5 do the section outline scanning of tyre bead-crown-tyre bead to tire 6, and continuous coverage goes out the anglec of rotation of connecting lever 4 and the profile each point distance to laser range sensor 5, then this distance is converted to the radius of point to connecting lever 4 rotation centers.Finally, with polar coordinates, angle and radius two column datas are depicted as to continuous curve on computers, this curve is exactly the measured tyre contour outline line arriving.
Claims (3)
