Centre inclines, and forms afocal " V " word angle, wherein, the angle of two sides (11,12) and track horizontal plane is 70~
85 degree (see the angle in Fig. 5), preferably 80 degree so that the following width of the measurement base 1 is slightly less than the spacing of track, the folder
Angle angle is the acute angle of measurement, and the side of the left and right two (11,12) is not orthogonal to orbital direction, but being formed has certain angle
Angle be in order to adapt to different interorbitals away from demand.Former and later two sides (13,14) of the measurement base 1 are by two
Inclined plane composition with angle (obtuse angle), two inclined planes are symmetrical along center line,.Whole measurement base is along the centering center
Line is to being referred to as two parts.
Refer to again shown in Fig. 1, it is recessed to be respectively arranged with first consistent with the volume of level meter 2 in two measuring surface in left and right
To house the level meter 2, first groove 21 is located in two inclined planes groove 21, the bottom land of the first groove 21 for level angle not
Incline, wherein, two level meters 2 are respectively left and right directions and fore-and-aft direction arrangement, and level meter 2 is cuboid, sets two water
It is preferable that level 2 is placed on left and right sides searching equalization point effect.In specific to the present embodiment, two level meters 2 also distinguish position
In the both sides of graduated scale 3, first level meter 2 is located at centering center line upper right side, and front and rear setting (is put down on two sides long of cuboid
Row is in center line), for measuring the levelness of fore-and-aft direction, another level meter 2 is located at the lower left of centering center line, left
Right setting (two short sides of cuboid are in centerline direction), for measuring the levelness of left and right directions.Certainly, this area skill
Art personnel can also such as set it should be appreciated that the set location of level meter 2 is not limited to the position described in the present embodiment respectively
It is placed in the upper left side and lower right of centering center line.Level meter 2 may be configured as four, such as can on both faces be respectively provided with two
It is individual.
As the utility model one preferred embodiment, on the side of left and right two of the measurement base 1 respectively to
Outer extension forms one section of horizontally disposed support base 4, and the support base 4 is integrally formed with measurement seat, and support base 4 can regard one section as
Cuboid, its length is consistent with the length of the left and right sides of measurement base 1, and the height of support base 4 is not higher than the measurement base 1
Height, two surfaces up and down where support base 4 are punched peace parallel to plane where track respectively at the two ends of the support base 4
Equipped with adjusting screw 5 to adjust the level height of the measurement base 1, and horizontal direction skew and the skew of vertical direction, with
Keep whole machine balancing.Screw 5 in the present embodiment has four, and the height of screw 5 can be equal to, more than or less than support base
Highly.Screw 5 is supported in orbital plane, and the track of different model, regulation measurement base 1 are suitable for by the height of different screws 5
Levelness and equalization point, make its measurement more accurate.Further, since support base 4 is as cuboid, therefore this can also be supported
