Description
Technical field
The utility model relates to tire survey instrument technical field, more specifically says a kind of tire outside diameter measurement mechanism.
Background technology
In the 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 not of uniform size after dispatching from the factory, and tire not of uniform size can cause the shakiness of travelling after being arranged on same vehicle, very easily go out security incident.Therefore assembling person in the time of fit a tyre, all can measure under each prepackage tire outside diameter size whether consistent, and as long as conventional measurement is with the tape measure estimation, error ratio is larger.
At present, be designed with a kind of machinery and equipment of measuring the tire outside dimension for tire production producer on the market, as ZL201010563305.5, a kind of by utilizing the size and shape of spatial digitizer detection tire, with the device of identification tyre type.Tire recognition device of the present invention is connected with user terminal with spatial digitizer, and comprises the tire specification database, and it is registered with the 3 d scan data for a plurality of tires in advance; And identification module, the 3 d scan data that the 3 d scan data that transmits with described spatial digitizer of retrieval has identical patterns in described tire specification database, and the corresponding tyre model of the 3 d scan data that retrieves is offered to user terminal.Described 3 d scan data is the data cloud of the meander-shaped for meaning the tyre side end face and any one of line profile data.
Yet such advanced person's tire specification checkout equipment, cost is very huge beyond doubt, so its popularity rate is little.And vehicle production producer still needs each tire of measurement of being responsible in assembling in vehicle tyre, a kind of so easily, easily, cheap, easy-operating tire specification testing tool is just very welcome.
The utility model content
The purpose of this utility model is to overcome the prior art tire specification and detects inconvenient defect, provide a kind of easily, easily, cheap, easy-operating tire outside diameter measurement mechanism.
In order to reach above purpose, the utility model is achieved through the following technical solutions: a kind of tire outside diameter measurement mechanism, it is characterized in that, and comprise a base bar, be connected with a fixed claw on a wherein end of described base bar, be connected with a movable claw on the other end; Be provided with a rule on the end face of described base bar, the scale starting point of described rule is positioned on the tie point of described fixed claw and base bar.
Detection method: the 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, slide and be provided with a positioning block.
In order to guarantee accuracy of measurement, if namely guarantee that two tire outside diameter outer rims that fixed claw and movable claw capture are symmetrical (whether being the external diameters of tire), at base bar middle part, a positioning block is set, locating piece and tire endoporus adapt, while detecting so, what locating piece just can guarantee the rule measurement is the external diameter of tire again.After installing pilot hole additional, need during detection first locating piece to be buckled in the tire endoporus, then from movable claw layback base bar, make fixed claw lean on the external diameter outer rim of a side, finally as long as mobile movable claw reading out data.
As preferably, described locating piece both end sides is a radian setting and tire diameter adapts.
Play positioning action in order to facilitate locating piece to buckle into the tire endoporus, the outer rim shape of locating piece is designed to radian and tire diameter is suitable.
As the alternative of such scheme, be provided with a positioning disk adapted with tire diameter under described locating piece, described positioning disk is coupling on described locating piece.
A kind of more complete positioning block structure of function of replacing such scheme is provided here again, and during said structure is stuck in the tire endoporus because of locating piece when measuring same tire external diameter multi-group data, pivoting friction is larger, so rotate cumbersome.Improved this programme arranges a positioning disk by the pilot hole below, by positioning disk replacement locating piece, is navigated in the tire endoporus and is gone, and then locating piece can easily rotate and just can measure multi-group data with respect to positioning disk.
As preferably, the external diameter of described positioning disk increases in the axial direction from lower to upper gradually.
Here positioning disk has been done to further restriction, mainly that the tire endoporus is diminishing from inboard, axial lateral, so positioning disk, for better laminating tire endoporus, causes each measurement data more accurate, positioning disk has also been made the modification of suitability in the axial direction.
As preferably, rule is arranged in the opening groove on the base rod end surface.
Here rule has been done to further restriction; main cause is easily scratched the rule surface in the moving process of movable claw; in the course of time; rule has not just existed; so an opening groove is set; by rule be arranged on the inside, like this movable claw in moving process, just touch less than, protected rule.
Beneficial effect: (1) whole detection method is very simple, very convenient, easy to operate.
(2) it is the external diameter of tire that the locating piece installed additional is positioned in the tire endoporus what guaranteed that rule measures by device.
(3) improved positioning disk replacement locating piece navigates in the tire endoporus and goes, and then locating piece can easily rotate and just can measure multi-group data with respect to positioning disk.
(4) for better laminating tire endoporus, cause each measurement data more accurate, positioning disk has been made increasing and design gradually from lower to upper of suitability in the axial direction.
(5) rule is arranged on to opening groove the inside, like this movable claw in moving process, just touch less than, protected rule.
