Description

Tire outside diameter measurement mechanism
Technical field
The present invention relates to tire survey instrument technical field, is more particularly a kind of tire outside diameter measurement mechanism.
Background technology
In finished car making-up shop, especially special vehicle making-up shop, the tire of each car is many, as special purpose vehicle 8*8-2 vehicle just has 8 wheels, the model of tire differs, and size is just different, the more important thing is that the tire of same model also has after dispatching from the factory not of uniform size, and tire not of uniform size is arranged on to cause after on same vehicle and travels unstable, very easily go out security incident.Therefore assembly operator under all measuring when fit a tyre each prepackage tire outside diameter size whether consistent, as long as and the measurement of routine tape measure estimation, application condition is large.
At present, be designed with a kind of machinery and equipment measuring tire outside dimension on the market for tire production producer, as ZL201010563305.5, a kind of size and shape by utilizing spatial digitizer to detect tire, to identify the device of tyre type.Tire recognition device of the present invention is connected with spatial digitizer and user terminal, and comprises tire specification database, and it is registered with the 3 d scan data for multiple tire in advance; And identification module, in described tire specification database, retrieve the 3 d scan data that the 3 d scan data transmitted with described spatial digitizer has identical patterns, and the corresponding tyre model of the 3 d scan data retrieved is supplied to user terminal.Described 3 d scan data is any one in the data cloud of meander-shaped for representing tyre side end face and line profile data.
But so advanced tire specification checkout equipment, cost is very huge beyond doubt, so its popularity rate is little.And vehicle manufacturers still needs each tire of measurement be responsible for when assembling vehicle tyre, a kind of so easily, easily, cheaply, easy-operating tire specification testing tool is just very welcome.
Summary of the invention
The object of the invention is to overcome prior art tire specification and detect inconvenient defect, provide a kind of easily, easily, cheap, easy-operating tire outside diameter measurement mechanism.
In order to reach above object, the present invention is achieved by the following technical solutions: a kind of tire outside diameter measurement mechanism, is characterized in that, comprises a base bar, wherein one end of described base bar is connected with a fixed claw, the other end is connected with a movable claw; The end face of described base bar is provided with a rule, and the scale starting point of described rule is positioned on the tie point of described fixed claw and base bar.
Detection method: base bar leans against on tire axle side, fixed claw fastens tire one external diameter outer edge side, mobile movable claw fastens the external diameter outer edge side of tire offside, then the size read on rule is write down, detect each tire and do lower record, detector for outer diameter error all can think qualified within 0.5cm, installs in the lump.Whole detection method is very simple, very convenient, easy to operate.
As preferably, on the middle part of described base bar, slip is provided with a positioning block.
In order to ensure accuracy of measurement, if namely guarantee that two tire outside diameter outer rims that fixed claw and movable claw capture are symmetrical (being namely whether the external diameters of tire), in the middle part of base bar, a positioning block is set, locating piece and tire endoporus adapt, when detecting so again, the external diameter of what locating piece just can ensure that rule measures is tire.After installing pilot hole additional, need during detection first locating piece to be buckled in tire endoporus, then from movable claw layback base bar, fixed claw is leaned in the external diameter outer rim of side, as long as last mobile movable claw reads data.
As preferably, described locating piece both end sides is that a radian arranges and adapts with tire diameter.
Conveniently locating piece buckles into tire endoporus and plays positioning action, the outer rim profile design of locating piece is become radian and tire diameter suitable.
As the alternative of such scheme, be provided with a positioning disk adapted with tire diameter immediately below described locating piece, described positioning disk is coupling on described locating piece.
Here reoffer the positioning block structure that a kind of function of replacing such scheme is more complete, said structure is when measuring same tire external diameter multi-group data because locating piece is stuck in tire endoporus, and pivoting friction is comparatively large, so rotate cumbersome.This programme improved, then by arranging a positioning disk below pilot hole, being navigated in tire endoporus by positioning disk replacement locating piece and going, and then locating piece easily can rotate relative to positioning disk and just can measure multi-group data.
As preferably, the external diameter of described positioning disk increases in the axial direction from lower to upper gradually.
Here further restriction has been done to positioning disk, mainly tire endoporus is diminishing inside axial lateral, so positioning disk is in order to tire endoporus of better fitting, cause each measurement data more accurate, positioning disk has also made the amendment of suitability in the axial direction.
As preferably, rule is arranged in the opening groove in base rod end surface.
Here further restriction has been done to rule; main cause easily scratches scale surface in the moving process of movable claw; in the course of time; rule has not just existed; so arrange an opening groove; rule is arranged on the inside, such movable claw just to touch in moving process less than, protect rule.
Beneficial effect: (1) whole detection method is very simple, very convenient, easy to operate.
(2) it is the external diameter of tire that device is positioned in tire endoporus what ensure that rule measures by the locating piece installed additional.
(3) the positioning disk replacement locating piece improved navigates in tire endoporus and goes, and then locating piece easily can rotate relative to positioning disk and just can measure multi-group data.
(4) in order to tire endoporus of better fitting, cause each measurement data more accurate, what positioning disk had made suitability in the axial direction increases design from lower to upper gradually.
(5) rule is arranged on inside opening groove, such movable claw just to touch in moving process less than, protect rule.
