Described measuring stick fixture is bolted on claw.
Described measuring stick fixture is provided with U-shaped groove, and bolt passes U-shaped groove the measuring stick fixture is fixed on claw.
A kind of measuring method of vacuum booster nominal diameter measuring instrument, described measuring method comprises the following steps:
1), the claw at claw two ends is placed on the vacuum booster periphery;
2), by the measuring stick test to and the vacuum booster Surface Contact, and screw bolt the side length bar be fixed on the measuring stick fixture;
3), from claw, unload measuring stick fixture and measuring stick secured together;
4), measure the distance of termination, measuring stick bottom to the measuring stick fixture;
5), calculate or table look-up and draw the vacuum booster nominal diameter.
The present invention compared with prior art, has the following advantages:
1, the data of measuring by measuring stick, then can be calculated vacuum booster nominal diameter parameter through conversion, data are accurate;
2, easy to use, the operating space demand is little, is applicable to vacuum booster spatial character on every side;
3, disassemble under state vehicle is non-, can measure, can guarantee that vacuum booster is harmless;
4, measuring instrument is simple in structure, is convenient to manufacture.

Embodiment
Below contrast accompanying drawing, the description by embodiment, be described in further detail the specific embodiment of the present invention.
As depicted in figs. 1 and 2, this vacuum booster nominal diameter measuring instrument, comprise measuring stick 1 and the claw 4 and the measuring stick fixture 3 that are provided with two claws, during measurement, two claws are stuck on vacuum booster 6 peripheries, distance between two claws of claw 4 is definite value, claw top is provided with measurement datum, has the through hole suitable with measuring stick at the measurement datum middle part, and measuring stick can be slided in through hole; Side at through hole has threaded hole, and measuring stick fixture 3 is provided with U-shaped groove, by hand-tight bolt I 2, passes U-shaped groove and coordinates with threaded hole, and measuring stick fixture 3 is fixed on claw, and U-shaped groove is convenient to the measuring stick fixture and is taken off from claw; Measuring stick fixture 3 is provided with the open slot slid through for measuring stick, by the hand-tight bolt II 5 on the measuring stick fixture, can tighten up open slot and clamp measuring stick.
Wherein, measuring stick 1 is circularity, linearity pole preferably, and is carved with scale mark thereon; Face and measuring stick axis that claw matches with the measuring stick fixture are perpendicular, and namely measuring stick axis and measurement datum are perpendicular.
The geometrical principle of this measuring instrument:
The circle of two different-diameters is in the situation that the identical bow of its chord length height is different, and the high value of the less bow of diameter is larger.
The distance of claw two claws of measuring instrument is fixed, while measuring the vacuum booster of different-diameter, the measurement datum of measuring instrument claw is different to the distance L of vacuum booster circle, and the L of the high larger correspondence of bow is just less, in Fig. 7, L3 is greater than L2, L2 is greater than L1.
The vacuum booster nominal diameter of take is of a size of the example that is of 10 cun, actual booster external diameter is 10 cun left and right, for the continuity of considering parameter is set as (9.5 cun by 10 cun intervals of nominal diameter value, 10.5 very little), the interval of this interval corresponding L value, by measuring the L value that each booster is corresponding, the interval that inquiry L value is positioned at, in Table 1, can obtain the outside dimension of corresponding booster.
In this example, two claw spacings of measuring instrument claw are 100mm, the content of the different tables 1 of the structural correspondence of different characteristic parameter claws.
The content of table 1 can be engraved on measuring stick in advance according to several relations, needn't unload like this measuring stick measurement and table look-up, namely can directly observe between the scale area of exposing on measuring stick fixture top and read the nominal diameter parameter.
Table 1 is the nominal diameter question blank
As shown in Figures 3 to 6, for measuring operation chart, this measuring method comprises the following steps:
1), the claw at claw two ends is placed on the vacuum booster periphery;
2), by the measuring stick test to and the vacuum booster Surface Contact, and screw bolt the side length bar be fixed on the measuring stick fixture;
3), from claw, unload measuring stick fixture and measuring stick secured together;
4), measure the distance L value of termination, measuring stick bottom to the measuring stick fixture;
5), calculate or table look-up and draw the vacuum booster nominal diameter.
The above is exemplarily described the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subject to the restrictions described above; the improvement of the various unsubstantialities that design of the present invention and technical scheme carry out as long as adopted; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
