Description
Technical field
The present invention relates to fields of measurement, be specifically related to measurement mechanism and the measuring method of the clamping power of wheel cover and wheel rim.
Background technology
In the design process, the clamping power of wheel cover and wheel rim is one of important indicator of designing of wheel cover to plug-in wheel cover.Clamping power specifically comprises wheel cover pressing-in force and wheel cover pull-out force.Pressing-in force judges that wheel cover is installed to the operation convenience on wheel rim, and pull-out force judges the connection reliability between wheel cover and wheel rim.At the beginning of design, usually use design software to carry out the analysis of power, obtain the important parameter such as wheel cover deflection and wheel cover claw size.After design completes, wheel cover needs to carry out bench test and verifies that whether wheel cover clamping power is consistent with design result.
In prior art, the pull-out force of wheel cover and wheel rim is measured as shown in Figure 1, wheel cover 2 is after being assembled to wheel rim 1, with hanging enough 3 through being connected on dynamometer 4 after the air vent of wheel cover 2, operating personnel pull dynamometer 4 and directly measure, and the reading of the dynamometer 4 when wheel cover comes off is denoted as pull-off force value.The measurement of current pull-out force generally direct use dynamometer 4 is simply measured, and the randomness of manual operation is very large to Influence on test result.Meanwhile, realize wheel cover 2 to be difficult to measure with the pressing-in force of the clamping of wheel rim 1.
Summary of the invention
The object of the invention is to realize to measure more accurately the pressing-in force of wheel cover and wheel rim and pull-out force.
For achieving the above object, The embodiment provides following technical scheme:

Embodiment
With reference to figure 2, Fig. 3, in two figure, indicate the wheel rim 14 as measuring object simultaneously.The measurement mechanism of the wheel cover of the present embodiment and the clamping power of wheel rim comprises: rack bracket, dynamometer link 10, dynamometer 12, link up with the pin 17 shown in 13 and Fig. 8 and Fig. 9.Rack bracket has base plate 5, the first relative vertical rod 6 and the second vertical rod 7 be fixed on base plate 5, to be fixed between the first vertical rod 6 and the second vertical rod 7 and the cross bar 9 be positioned at above base plate 5.In the present embodiment, what the first vertical rod 6 and the second vertical rod 7 all adopted is kit form that multiple rod member forms, these rod members form stable triangular shaped.First vertical rod 6 and the second vertical rod 7 all have pin draw-in groove 8.In fact, base plate 5 also can be rod member or plate, or directly using ground or table top as base plate 5, now the first vertical rod 6 and the second vertical rod 7 is directly fixed on ground or table top.Dynamometer link 10 has external thread, dynamometer link 10 through cross bar 9 and with setting nut 11 threaded engagement be placed on cross bar 9.Setting nut 11 can be fixed or be placed in actively on cross bar 9, when setting nut 11 is fixed, the height of dynamometer link 10 can be adjusted by rotating dynamometer link 10, and when setting nut 11 is movable, the height of dynamometer link 10 can be adjusted by rotating adjusting nut 11.Dynamometer 12 is connected to the lower end of dynamometer link 10, and dynamometer 12 lower end is provided with hook annulus 15.Hook 13 can be hung on the hook annulus 15 of dynamometer 12 lower end, or do not adopt hook annulus 15 and adopt such as rivet, be threaded, the alternate manner such as welding connects dynamometer 12.
With reference to figure 4, when measuring the pull-out force of wheel cover 16 and wheel rim 14, wheel cover 16 has been connected on wheel rim 14, now link up with 13 to be connected with wheel cover 16 after pass wheel cover 16 air vent be connected on the hook annulus 15 of dynamometer 12 lower end.
With reference to figure 5, this figure indicates the hook 13 that the present embodiment adopts, and this hook 13 is the annulus composition of many shackles and shackles lower end.But in use also can adopt the hook 13 of other form multiple, such as, adopt the form of the chain of two ends buckle.
With reference to figure 6, measuring the starting stage of wheel cover 16 with the pull-out force of wheel rim 14, need wheel rim 14 to be fixed on base plate 5.Then, be connected on dynamometer 12 after hook 13 being connected with wheel cover 16.Then wheel cover 16 is snapped fit onto syndeton wheel rim 14 formed as shown in Figure 4.Then rotation dynamometer link 10 or setting nut 11 adjust the length that dynamometer link 10 stretches to base plate 5, namely adjust the height of dynamometer link 10, make hook 13 tensioning as shown in Figure 6.Reading now on dynamometer 12 is the reading of the gravity of hook 13 itself, record dynamometer 12 now, or carries out zero setting to dynamometer 12.
With reference to figure 7, continue the height of adjustment dynamometer link 10 until wheel cover 16 is pulled into state shown in Fig. 7 from wheel rim 14 by hook 13.Dynamometer 12 can read to obtain a full-scale reading in the process, in step shown in Fig. 6 when dynamometer 12 zero setting, this full-scale reading is the pull-out force of wheel cover 16 and wheel rim 14, and when dynamometer 12 non-zero setting, the reading deducting the gravity of hook 13 with maximum reading is the pull-out force of wheel cover 16 and wheel rim 14.In the measuring process of pull-out force again, operating personnel rely on dynamometer link 10 to apply stable, that direction is constant pulling capacity with the threaded engagement of nut 11 to wheel cover 16, measurement result more accurate.
With reference to figure 8, when carrying out the pressing-in force of wheel cover 16 with wheel rim 14 and measuring, need to adopt pin 17.When measuring, wheel rim 14 is fluidly placed on base plate 5.Then, hook 13 is connected on wheel rim 14, and through being connected on dynamometer 12 after the air vent of wheel cover 16, now linking up with 13 can be applied with pulling force to wheel rim 14 and not provide upper pulling force to wheel cover 16, and the buckle on wheel cover 16 can keep aliging by hook 13 with the buckle on wheel rim 14.Then pin 17 being snapped in pin draw-in groove 8 makes it be positioned in the first vertical rod 6 and the second vertical rod 7.Pin draw-in groove 8 can leave in the differing heights position of the first vertical rod 6 and the second vertical rod 7 to adapt to the wheel rim of different model.In actual use, pin 17 immovably can also be positioned in the first vertical rod 6 and the second vertical rod 7 by bayonet lock, bolt by technician, or adopts the connection such as slide rail or tooth bar pin 17 it to be positioned at movably in a vertical rod 6 and the second vertical rod 7.Then, the height adjusting dynamometer link 10 by rotating dynamometer link 10 or setting nut 11 makes wheel rim 14, wheel cover 16 is pulled up until wheel cover 16 just and pin 17 fit, now pin 17 does not apply pressure to wheel cover 16, record dynamometer 12 reading, the now reading of dynamometer 12 equal wheel rim 14, wheel cover 16 and hook 13 gravity and.If now will survey the registration zero setting of meter 12, then reading is zero.
With reference to figure 9, continue the height of adjustment dynamometer link 10, hook 13 continues pull-up wheel rim 14, until wheel cover 16 is pressed into wheel rim 14 by pin 17, now record the reading of dynamometer, this reading equal the gravity of wheel rim 14, wheel cover 16 and hook 13 and the pressing-in force that applies of pin 17 pairs of wheel covers 16 and.Two readings of dynamometer 12 are subtracted each other, namely equals wheel cover 16 and the value of the pressing-in force of wheel rim 14, achieve the measurement of pressing-in force.
Although the present invention is described in conjunction with above embodiment, but the present invention is not limited to above-described embodiment, and only by the restriction of claims, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present invention and scope.
