It is characterized in that：Support leg is fixed on the bottom plate, support leg is fixedly arranged above a pair of parallel horizontally-supported cylinder,
Vertical panel is being installed at horizontal supports；Valve port plug-in unit vertical pole is installed, valve port is inserted on the bottom plate
Part vertical pole is equipped with valve port plug-in unit cross bar by articulated manner, and valve port plug-in unit cross bar end includes valve port plug-in unit.
Round lightening hole is distributed in the preferred aspect of the utility model, the bottom plate.
At the preferred aspect of the utility model, the horizontally-supported cylinder is cylinder.
At the preferred aspect of the utility model, the horizontally-supported cylinder is made of nylon.
At the preferred aspect of the utility model, when the wheel diameter that fixture is applicable in is D, the horizontally-supported cylinder
A diameter of 0.13D-0.17D, the distance between described central shaft of horizontally-supported column are 0.65D-0.72D.
At the preferred aspect of the utility model, when the wheel diameter that fixture is applicable in is D, the horizontally-supported cylinder
A diameter of 0.145D, the distance between described central shaft of horizontally-supported column are 0.685D.
At the preferred aspect of the utility model, the top edge of the vertical panel and the horizontally-supported cylinder it is upper
Edge is concordant.
The advantages of fixture of the utility model, is, realizes the higher stability of fixture, and easy to operate, contributes to
The realization of accurate three coordinates operation.

Specific implementation mode
Embodiment 1
In the present embodiment, a kind of fixture for vehicle measurement and positioning is provided, the fixture includes bottom plate, support
Foot, horizontally-supported cylinder, vertical panel, valve port plug-in unit vertical pole, valve port plug-in unit cross bar, valve port plug-in unit, it is characterised in that：
Support leg is fixed on the bottom plate, support leg is fixedly arranged above a pair of parallel horizontally-supported cylinder, perpendicular to water
Vertical panel is installed at flat supporter；Valve port plug-in unit vertical pole is installed, valve port plug-in unit vertical pole passes through on the bottom plate
Articulated manner is equipped with valve port plug-in unit cross bar, and valve port plug-in unit cross bar end includes valve port plug-in unit.Divide on the bottom plate
It is furnished with round lightening hole.The horizontally-supported cylinder is cylinder, and is made of nylon.When the wheel diameter that fixture is applicable in is
When D, the distance between the central shaft of a diameter of 0.145D of the horizontally-supported cylinder, the horizontally-supported column are
0.685D.The top edge of the vertical panel is concordant with the top edge of horizontally-supported cylinder.
Embodiment 2
In the present embodiment with embodiment 1 difference lies in, when fixture be applicable in wheel diameter be D when, the level
A diameter of 0.13D of support cylinder, the distance between described central shaft of horizontally-supported column are 0.72D.
Embodiment 3
In the present embodiment with embodiment 1 difference lies in, when fixture be applicable in wheel diameter be D when, the level
A diameter of 0.17D of support cylinder, the distance between described central shaft of horizontally-supported column are 0.65D.
Comparative example 1:
The comparative example 1 and embodiment 1 difference lies in, horizontally-supported cylinder is replaced with down to the inclined-plane of isosceles triangle,
The angle of inclined-plane and horizontal plane is 15 degree.
Embodiment 4
In the present embodiment, it is measured using Zeiss three-coordinate instrument, wheel is 20 cun of aluminum-alloy wheels.
In the present embodiment, bottom plate is located in three-coordinate instrument marble platform first, wheel is placed on horizontal branch
On dagger body, and make wheel disc front face close to vertical panel.Then use valve port plug-in unit vertical pole and valve port plug-in unit
The position of cross bar is adjusted, and the valve port plug-in unit of end is inserted into valve port.
Then in the case of the equipment of fixed embodiment 1-3 and comparative example 1, respectively to the same wheel sample to be tested
Outer rim same position close to valve port measures.The measurement difference of individual device is parallel to be carried out 32 times, and will be measured
After value deducts its arithmetic mean of instantaneous value, it is recorded in table 1.
Table 1：Measured value under the conditions of embodiment 1-3 and the fixture of comparative example 1 deducts arithmetic mean of instantaneous value result
It can be seen that, embodiment 1-3 has lower standard for the fixing device of other forms from table 1
Deviation.When this shows using fixture described in the utility model, can to avoid partially due to ambient vibration and the measurement that brings misses
Difference.In particular, under the conditions of finding the setting of embodiment 1, standard deviation smaller shows that the error measured further decreases.
