Description
Technical field
The present invention relates to a kind of methods of automatic measurement tire outer perimeter, overall diameter, further relate to a kind of automatic measurement tire
The device of outer perimeter, overall diameter.
Background technique
Tire is at home and abroad required to carry out endurance test, carrying out tire outer perimeter after high-speed test (HST), outer in tire standards
The measurement of the detection projects such as diameter.
Measurement tire outer perimeter specified in national standard " tire physical dimension measurement method " GB/T 521-2012, outer at present
The method difference of diameter is as follows:
The measurement method of tire outer perimeter: with metallic tape rule along crown center line or close to center line highest point around tire one
Measure outer perimeter in week.Measured value unit is millimeter, round numbers.
The measurement method of tire overall diameter: tire overall diameter: D=L/ π is obtained using calculating method, in formula: straight outside D- tire
Diameter, unit are millimeter (mm)；L- tire outer perimeter, unit are millimeter (mm)；π-pi, takes 3.14.The number of tire overall diameter
According to the result revision of the convention to integer.
The measurement work that the above method manually carries out tire outer perimeter, overall diameter is all made of in industry at present.Because of wheel
For tire after the high-speed test (HST) for carrying out long-time, the endurance test of high load capacity or short time, high speed, tire will appear delamination, tire
The defects of side breach, open splice, cords break, there is the risks blown out.Existing measurement method has the disadvantage in that
1. tire after durable, high-speed test (HST), can generate a large amount of glue foams and be attached to tire crown surface, when measurement, glue foam
It can be adhered to the metallic tape rule back side, be not easily cleaned.Cause testing result bigger than normal, detection data is caused to generate deviation；
2. tire is after durable, high-speed test (HST), because crown rubs for a long time, crown, tire shoulder surface temperature are high, and crown is general
78 DEG C or so are maintained, tire shoulder is typically maintained in 88 DEG C or so.Testing crew is when measuring, situations such as easily scald,
Simultaneously because the part chemical substance in high temperature tyre stock decomposes volatilization, threaten to the life and health of testing crew；
3. testing crew measures tire outer perimeter, overall diameter, the tire after test is in explosive state, easily to examination
The life security for testing personnel threatens.
Therefore, it is necessary to propose effective technical solution, solve the above problems.
Summary of the invention
The present invention in view of the above shortcomings of the prior art, provides the device of a kind of automatic measurement tire outer perimeter, overall diameter
And method.Tire may be implemented after endurance test, high-speed test (HST) in the device and method, automatic measurement tire it is outer straight
Diameter, and can get tire outer perimeter.
The technical scheme to solve the above technical problems is that
The device of a kind of automatic measurement tire outer perimeter, overall diameter, including rack, the straight line being installed in the rack are led
Rail, the tire station axis with the removable connection of the linear guide, the displacement sensor being installed in the linear guide, installation
In the optoelectronic switch in the rack and close to institute's displacement sensors lower left side, it is installed in the rack and is located at institute's rheme
Displacement sensor lower right close to switch；Institute's displacement sensors and the tire are arranged in parallel, the optoelectronic switch and described
Tire coaxial arrangement.
The present invention also provides a kind of method of automatic measurement tire outer perimeter, overall diameter, step includes:
(1) tire is fixed on tire station axis, tire, which is moved by tire station axis along linear guide, reaches close
When close to switch, close to closing the switch, optoelectronic switch is opened, displacement sensor record at this time tire centerline point in displacement sensor
On corresponding points at a distance from the zero point of displacement sensor be D1, corresponding points of the optoelectronic switch central point on displacement sensor with
The distance of starting point is D3, and wherein starting point refers to position of the central point of tire on displacement sensor；
(2) the tire station axis is moved along linear guide again and reaches tire front end and blocks optoelectronic switch, optoelectronic switch
Closure is opened close to switch, and corresponding points of the tire centerline point on displacement sensor and displacement pass displacement sensor record at this time
The distance of the zero point of sensor is D2；
(3) diameter of tyres D, D=2* [D3- (D2-D1)] are obtained according to D1, D2, D3 that step (1) and (2) obtain.
It is manually measured the utility model has the advantages that the present invention is alternative, detection accuracy, accuracy are higher than manually measuring, inspection
It is accurate to survey result, while the life and health of testing crew, safety are ensured.
